REGIONAL SPECIALIZATION AND INDUSTRIAL CONCENTRATION IN THAILAND, 1996-2005
Pansuwan, Apisek
trade liberalization, industrial location policy, industrial concentration, regional specialization, regional development
This paper provides a descriptive analysis of the changes in the industrial and spatial concentration that occurred in Thailand from 1996 to 2005. Based on the data from the Department of Industrial Work of the Ministry of Industry and using the Hirschman-Herfindahl index of concentration, the geographical concentration of industries in the study regions was measured. The Hirschman-Herfindahl index has the useful property of being decomposable into sources of changes in the concentration. Moreover, location quotient was also used to measure the regional specialization of the manufacturing industries in Thailand. Results of the analysis indicated that from 1996 to 2005, the decrease in the spatial concentration of manufacturing as well as in the regional specialization in manufacturing in Thailand remained stable to a lesser extent. The results have also indicated that most factories continue to be concentrated in Bangkok and its neighboring areas. It can therefore be best argued that in the case of Thailand, the effect of its trade liberalization policy has been more powerful than its industrial decentralization policy.

Pangaribowo, Evita Hanie
Harini, Rika
comparative, advantage, agricultural, sector
Comparative advantage is measured using economic and social values. Comparatively superior commodities mean that they are produced in an economically efficient way. Agricultural sector is the one that is prioritized in Kulon Progo Regency and, thus, purposively that region is employed as the sample of this study. Research is based on the analysis of secondary and primary data collected through interviews with 60 respondents. The respondents consist of 2 groups of rice field farmers in Lendah Sub-district, Kulon Progo Regency, which constitutes the predominant crop field area. The analysis is conducted descriptively using the Policy Analysis Matrix method. Based on the cost-benefit analysis, rice commodity agribusiness in Kulon Progo regency has privately generated average financial profit amounting to Rp. 2, 18 million per season. Meanwhile, it is socially and economically generating relatively large profit amounting to Rp. 4.58 million per season. The level of rice field economic efficiency amounts to 0.747. These values demonstrated that rice agribusiness has comparative advantage which means that producing rice commodities in Kulon Progo Regency is more cost effective than importing them.

FLOW PATTERNS OF VEHICULAR TRAFFIC ALONG HIGHWAY TOLL PLAZA IN OGUN STATE
Raji, Bashiru A.
Muse, O. Solanke
flow pattern, vehicular traffic, toll plaza
Congestion on our highways, freeways and arterials are increasing at an alarming rate. This occurs because there is an increase in vehicular growth without a corresponding increase in road size, and this has made free flow of traffic a preponderant problem in our highways. Toll plaza causes delay on our highways and results are formation of queue. This paper examined how simple queuing model can be used to determine traffic intensity and the flow pattern of car traffic at a toll plaza. The study was carried out with twelve field assistants at Ogere toll plaza in Ogun State. Findings show a significant variation in the degree of hourly traffic intensities at the four pay points for cars at the toll plaza. However, variation in the daily traffic intensities at the four pay points for cars showed no significant variation. The study also revealed that bumps constructed to check vehicles speed, hawker’s trading activities are among other factors that constitute hindrance to free flow of traffic other than service time and inter-arrival time of cars at the toll plaza. It is therefore recommended that appropriate authority should look into these factors and take necessary steps towards ensuring free flow of traffic at the plaza.

LAND DEGRADATION ASSESSMENT, IN THE PERI-URBAN AREA OF KADUNA METROPOLIS, NIGERIA
Oluwafemi, Adewuyi Taiye
Conservation, Degradation, Environment, Land use, Land cover
This study assessed land degradation in the peri-urban area of Kaduna metropolis from the perspective of land use and land cover with the aim of ascertaining the role of these variables and to suggest on how to manage their existing nature and characteristic. Random sampling method was used to collect data from field observation, measurement and semi-structured interview which are summarized and analyzed using descriptive statistics and presented in the form of tables and photographs. The results indicated that the existing nature and characteristic of land use and land cover cannot be exonerated from contributing to ongoing land degradation in the area for the following reasons: first, 6% of the area is already degraded, second, low average values for surface cover index (12.7%), leaf cover index (11.4%) and tree density (101 per 25,000m2), third, lost of vegetation biodiversity, fourth, absent of adequate conservation techniques to reduce the effects of crop farming and animal husbandry and lastly, evidence of problems already created by soil mining and refuse dumping. The situation in the study area calls for adequate land use and land cover planning, monitoring and management.

FARMING PRACTICE IN A FLOODPLAIN VILLAGE OF ASSAM (INDIA): CONTINUITY AND CHANGE
Deka, Nityananda
Bhagabati, A. K.
farming practice, floodplain village, traditional farming, sustainability, cropping technology
Farming practice in a floodplain environment holds great ecological,economic and social significance. In many cases, agriculture is modernizedwithout caring much for the local environmental conditions. The traditionalfarming practices, although relatively less productive, are more often than not ecofriendlyand sustainable. This paper attempts to study the farming practicesfollowed in a floodplain village of the Brahmaputra valley, Assam, India in termsof cropping practice, inputs and crop protection measures, methods of harvestingand threshing and changes in cropping technology. The study is based on (i)primary data collected from all the 408 households of the village through apurposively designed survey schedule, (ii) interviews with selected farmers andother local knowledgeable persons, and (iii) field observation made by the authors.The data and information thus generated have been summarized using simplestatistical and cartographic tools. The study reveals that the farming practice in thevillage is still traditional in nature with little application of modern inputs andimplements. The small size of landholding and scattering of plots and very limiteddiversification of the rural economy hinder the process of modernization of thefarming practice.

This research is carried out within two caves with underground river andone karst spring, which is located in Gunung Sewu karst area, Gunung Kidul. Theobjective of this research is to recognize some flood hydrograph properties of karstaquifer characterization in order to compare the comportment of aquifer to releaseits flow components between underground river and karst spring. Water level dataloggers are installed within two caves and one karst spring represent upper,middle, and lower elevation of karst topography, which are Beton, Seropan, andToto Cave, respectively. In addition, time series discharge measurement incorrespond to minimum, average, and maximum flow events is conducted toformulate the Annual Stage Discharge Rating Curve. Thereby, the full year riverhydrograph may be defined. Afterwards, by selecting several flood hydrographevents, the recession constant in each cave including diffuse flow (Kb), and fissureflow (Ki), and conduit flow (Kc) recession constant, is then calculated andcompared in every location. The result shows that Beton Spring that represents theupper part of research area confirms the quickest respond towards rainfall events.Also, this point specifies the medium number of diffuse recession constant(Kb=0.983), compared to Seropan (0.996), and Toto (0.937), means that theaquifer surrounding Toto Cave release its groundwater storage faster than BetonSpring and Seropan Cave. On the contrary, Seropan Cave performs the highestvalue of diffuse recession constant (0.996) and this situation is confirmed by its dryseason discharge that still above 810 lt/second.

THE INTERMEDIATE CITYY CONCEPT REVIEWED AND APPLIED TO MAJOR CITIES IN SUMATRA, INDONESIA
Withington, William A
A concept of "the intermediate city" has had various definitions as an analytically valuable tool in studying urban systems, particularly those in Less Developed Countries. The Intermediate City concept is reviewed and a flexible usage recommended through application of the concept to major cities in Sumatra, Indonesia. The nine major cities identified are examined for the 1961 – 1980 years in terms of their qualities as intermediate or major cities; distinctive changes during the period; and the extent to which these Sumatran intermediate cities may be representative of major cities in the broader urban system of Indonesia, Southeast Asia, and Monsoon Asia

Population in urban development and the practical problems of urban planning policy in Africa
Uyanga, Joseph
The paper analyses the pattern of recent growth in African towns, examines the population component in this growth process and discusses the attendant urban planning problems. The contention in the study is that there are problems of definition. policy enunciation, and organisational co-ordination in the conceptualization. planning. orchestration and implementation of urban development and service systems. The magnitude of African urban developmental problems, and its multi-faceted nature demands that the latest in scientific knowledge and technological innovations should be integrated and incorporated into the urban planning and implementation processes.

Geography with the environmental satellites
Etchegorry, J.P. Gastellu
Coarse spatial resolution, high temporal frequency data from the earth polar orbiting (NOAA. HACMM, Nimbus, etc.) satellites and from the geostationary (GOES. Meteosat, and GMS) satellites are presented to demonstrate their utility for monitoring terrestrial and atmospheric processes. The main characteristics of these ,satellites and of the instruments on board are reviewed. In order to be useful for environmental assessments. the remotely sensed data must be processed (atmospheric and geometric corrections, etc.). The NOAA Center provides a wide range of already processed data. such as meteorological. oceanic, hydrologic and vegetation products; o rough description of these preprocessed data is given in this article. Finally, some examples of applicotions in Southeast Asia and especially in Indonesia, are described, i.e.: agroecosystem, drought and oceanic monitoring. The paper concludes that coarse resolution, high temporal frequency ,satellite data are very valuable for environmental studies. the emphasis being laid on the improve. ment of the crop and drought assessment programmes.

Spot simulation for urban study
Dulbahri, Dulbahri
This paper discusses the SPOT simulation performances with Toulouse area as an example. An Overflight of the Toulouse area was made; resampling of 10 m and 20 m resolution combining with XS/ and XS2 in the creation of the simulation image was used in an effort to study Toulouse urban area. Manual interpretation without fieldchecks is used in this study. Toulouse urban land use can be distringuished and is easily delineated. Based on spectral characteristics, roof reflectance, road pattern, texture, and shape analysis the relative urbanization can be known. The relative network density can be measured so that the building and population density can be estimated using the SPOT simulation image.

Urban environment assessment: special reference to terrestrial and aerial photographic approaches
Yunus, Hadi Sabari
environment, urban
The following discussion particularly stresses the techniques or research methodologies concerned with urban environment assessment. Given the fact that monitoring the quality of the urban environment is prime, some practical approaches to that problem are seriously needed. Due to the complex nature of the urban environment in terms of the elements, interrelationships of elements, and dynamic nature of their interactions, the author devises a model in the form of a combination approach to assess the urban environmental condition.The variety of urban environments reflects the social, economic, cultural, political, technological and demographic background of the nation and accordingly there should be a wise selection of the applied techniques and the environmental criteria used for assessing the urban environmental condition.The combination approach is an integration of terrestrial and aerial photographic approaches. Since each of the aforementioned approaches has its own weaknesses, the combination approach is expected to cover those weaknesses and can give more effective, accurate and reliable data on the urban environmental assessments.

Environmental change and household livelihood strategies: preliminary observations from field work in different locations
Preston, David A
environment, farming
The theoretical framework and objectives of a study of environmental change and evolving household livelihood strategies, which will include field work in Central Java, are outlined. Preliminary results of previous, related field work in Luzon (Philippines) and highland Ecuador (South America) are reported. Two changes that seem of importance in both areas so far studied are the increasing importance of commercial farming in central locations (near to village centres) and the decreasing intensity of use of land on the periphery of rural communities. Preliminary observations in Central Java suggest that household livelihood strategies are more diversified than in either case study area in Luzon or Ecuador and that such diversification has increased through time. The relative importance of farming and the use of natural resources does not seem to have diminished.

SIR-A views our environment An Experiment in the Batu Angkal Area, West Kalimantan, Indonesia
Sutanto, Sutanto
Zuharnen, Zuharnen
Cloud cover is a serious problem for remote sensing in Indonesia. Some areas, around 10% to 20% of the land territory, are almost never cloud-free. The only system of remote sensing capable of overcoming cloud cover problem is that applying microwave energy. This article deals with a radar system being operated by the Columbia shuttle imaging radar A in 1981 in the Batu Angkal area, West Kalimantan, Indonesia. The choice of the study area is due to the availability of collateral material such as topographic map. land use map, and false color photographs.The study is aimed at learning the interpretability of SIR-A image of 1:500,000 which is blown up to 1:250,000 for the study of the.environment of this area. The method used in the identification of environment is applying the physical characteristics of objects (tone, texture, shape, size, direction in relation to the illumination, surface roughness, and dielectric constant) to trace it.The discernable elements of the environment of the study area are listed sequentially based on the ease of identqicaiton: rivers and dissected hills, unpaind forest and lowland forest, wetfields, and road and settlement.Factors affecting the ease of identification are. mainly tonal contrast, shape, size, surface roughness, direction in relation to the illumination, and dielectric constant. Due to the future availability of SIR-B image of Kalimantan, further study is recommended.

An annotated bibliography on geographic information systems applications in developing countries
Martha, Sukendra
Geographic Information Systems (GIS) are needed to assist national development because GIS can manipulate and analyze geographically-referenced data to support the decision making process of an organization. A problem faced in developing countries is that decision making is not always based on integrated information.This annotated bibliography is compiled for three reasons:1. The lack of GIS research in developing countries.2. Although GIS are potentially useful, because of the limited amount of publish ed research, there is little information available about GIS applications. Thisbibliography presents relevant publications to remedy this deficiency.3. It is believed that geographic information systems in developing countriesneed to be improved to facilitate the use of the integrated, comprehensive in formation to assist the country's development.This bibliography summarizes GIS procedures in general and GIS on selected countries: Costa Rica, Argentina, India, Bangladesh, Sri Lanka, and Indonesia.

Geography and regional development planning:linking understanding to action
Huisman, Henk
Mangunsukardjo, Karmono
The interest in regional development planning in Indonesia as well as in many other Third World countries is growing rapidly since the early 1970s. However, the subject matter of regional development planning is still in the process of taking shape. As a consequence, considerable differences exist regarding the interpretation of this field of enquiry and action. The present article aims at addressing three basic questions, i.e.: (i) What is the rationale for the introduction of planning for development on a regional basis? (ii) What types of regional development planning do exist and what are their respective characteristics? and (iii) What are the various implications of the spatial dimension of regional development planning for professional practice? As the understanding of the dynamic situation in an area in a holistic way is a sine qua non condition for the planning of effective development intervention, the input of geography in the regional planning process is indispensable.

New towns as growth centres A Case Study in Nigeria
George, E. Sokari
This paper criticizes the selection of seven new towns as growth centres in Rivers State. However, based upon financial constraint and other variables, it suggested only two locations suitable for growth centres. These centres are integrated with rural development policies to function as alternative destinations for rural migrants to the state's capital city and to strengthen the service hierarchies in the rural region, The general arguments are illustrated with a case study of Rivers State of Nigeria.

Population distribution and population growth in Yogyakarta special region
Mantra, Ida Bagus
The Sultanate of Yogyakarta which, during the struggle for independence and subsequently has been known as the Special Region of Yogyakarta, is located in the southern part of Central Java. It constitutes much of the heartland of Javanese culture, for Yogyakarta was the center of the pre-colonial Kingdom of Mataram.Within Yogyakarta Special Region, there is a marked contrast in the population density between Bantu! and Sleman regencies on one hand, and Gunung Kidul and Kulon Progo on the other hand. The basic reason for this difference is the fact that the soil of Bantul and Sleman regencies is primarily young and vulcanic, while there is also a good water supply and intensive irrigation network.The annual rate of population growth in Yogyakarta Special Region is much lower compared with other provinces in Java. During 1961 and 1971 the rate of population growth was 1.1 percent, for the period 1971— 1980 became 1.09 percent. This region experienced a net loss of population through migration, and that the losses were greater in the poor areas of Gunung Kidul and Kulon Progo

Marketing patterns of agricultural commodities in an upland area of Central Java
Ommeren, Caroline M. van
Palte, Jan G.L.
farming, agricultur
In the uplands of Central Java a wide variety of dry cultivated crops are produced for subsistence as well as for cash. The marketing channels for these crops are also diverse. The producers can choose between selling at the market place or at their farms; either to consumers or traders; or they can sell their products to wholesalers in the towns. However, this freedom of choice is not absolute and is determined by the quantity of the merchandise. Farmers/who can sell large amounts of produce are able to bypass some steps in the hierarchical order of market places or traders. Thus, producers with relatively large farmlands can sell their commodities in more profitable ways compared to those with /smaller farms. Moreover, the latter are often forced to sell their produce below market value to traders who provided them with advance or who bought the crop before harvest (tebasan), because of their need for cash

Evaluation of Gola River annual discharge: An Experience of Spring Fed Siwalik Mountain River
Pande, R. K.
river, mountain
The stream character as such and its discharge behavior are the gross results of a range of events and functions of nature. The word 'stream flow', as used in the present text, is referred to 'catchment yield'. This yield is obviously discharge, q, which has dimensions of volume, L3, and time, T, expressed here onwards in cumec (one cubic metre per second) which will ultimately be converted into a single voluminous unit litre (1) and hence referred to as Q. As the_ Gola River is a spring fed river,, its discharge behaviour is absolutely dependent on the sub-surface flow of Siwalik{ Ranges. It has been noticed that the sub-surface flow fluctuates according to the monsoonal and non-monsoonal precipitation intensity. Hence, an interesting seasonal rhythm is noticed in the monsoonal and non-monsoonal discharge with the changing values of stream magnitude and velocity.

Identifying settlements on the SIR-B images of Rimbobujang and the surrounding areas, Sumatra, Indonesia
Sutanto, Sutanto
electromagnetic spectrum, remote sensing
The use of remote sensing techniques is indispensable for Indonesia due to the large size of its territory, most of which is of difficult access and of little known regional potential. Some areas are covered by clouds almost all the year round so that remote sensing systems using visibilities up to the thermal portion of the electromagnetic spectrum fail to record them. There is no other way but to apply the microwave energy for such areas, the passive as well as the active one.This paper deals with the data extraction from Sir-B image of Rimbobujang area and its surroundings, in Sumatra, Indonesia, with special reference to the identification of settlements. It is a result of image interpretation followed by a three-days fieldchech in the study area. Comparison is also made with SPOT and La.ndsat MSS images.SIR-B image proves to be a reasonably good tool to identify rural settlement in an open area, especially for that with high density of houses. Its use to identify towns and cities is more recommended.

monthly probabilities for acquiring remote sensed data of indonesia with cloud cover less than 10 , 20 and 30 percent
Etcregorry, J.P. Gastellu-
The Indonesian spatiotemporal cloud cover distribution was quantified with the aid of GMS, Landsat and SPOT data. Iterative interactive factorial analyses grouped pixels with similar profiles into 18 classes for all land areas. For each class, statistics of Landsat and SPOT images, grouped by class, were used to verify, calibrate and improve class profiles. This led to quantified temporal profiles of probability of acquiring remotely sensed data with 10 , 20 and 30 percent cloud cover, for any Indonesian land area.

Water resources of the Chad Basin Region
Kaloko, Franklyn R.
River basin development is seen as a very effective means of improving agricultural productivity. In the Chad Basin area of the Sahelian Zone of the West African Sub-Region, the water resources have been harnessed to ensure viable agricultural programmes for Nigeria. However,the resultant successes have met by many problems that range from physical to socio-economic and of which water losses have been the most threatening. The study has called for the use of Hexa.deconal (C1-OH) film on the water surface of the Chad as a means of reducing evaporation.

Population mobility and the links between migrants and the family back home in Ngawis Village, Gunung Kidul Regency, Yogyakarta Special Region
Mantra, Ida Bagus
The total population of Yogyakarta Special Region was 2,966,549 persons in 1985, while the population density was 931 persons/sq.km. The Yogyakarta Special Region is one of the poor areas of Java in an economic sense.The annual rate of its population growth is much lower than those of other provinces in Java. The region experienced a net loss of population through migration. The losses were greater in the poor areas of Gunung Kidul, one of its regencies.This study aims at developing the knowledge on the nature and incidence of population mobility from the rural to the urban areas, and investigating the extent and nature of the links established and maintained between the area of origin and the area of destination, by temporarily returning migrants in Ngawis Village of Gunung Kidul.The main reason for migrating out of the village is an economic one. Although the greater part of returning migrants stated that their economic conditions improved after moving out, the income they receive monthly is still low. The link between migrants and their relatives back home is very intensive. They maintain contact by visiting, sending letters, money and goods, and exchange views and ideas on developmental issues.

Geomorphological approach to surficial material evaluation in the Serang River Basin Kulonprogo, Yogyakarta, Indonesia
Sutikno, Sutikno
This study deals with the evaluation of surficial material characteristics, based on landform units in the Serang River Basin. The approach concentrates on the use of geomorphological mapping by using aerial photo interpretation and field investigations. The landform units, as defined by geomorphological mapping, was used as sample areas to determine the surficial material characteristics. These characteristics include grain size, sphericity and roundness coefficient. The measurement of the material characteristics in the river bed was based on 100 gravel pebbles systematically sampled along the length profile of the river. During the survey, 14 cross sections were chosen. The potential of the alluvial material resources was estimated by their areal distribution, thichness sedimentary and characteristics.Among landform units in the studied area which contains a large amount of the materials are: natural levees, river terraces, river bed and hill foot slopes. Generally, the river bed materials decrease in grain size downstreams and increase in sphericity and roundness coefficient. In some cross sections a reversal was found to the general tendency. This situation might be due to human activities for getting material for construction. Due to human activities some environmental impacts occur.

Geomorphological analysis for assessment of coastal recreation sites in the coastal area of Trisik, Kulon Progo Regency, Yogyakarta Province
Woro, Suratman
Yunianto, Tukidal
The sand dunes and beach ridges area along the south coast of Yogyakarta Special Region are partly potential for a recreation site. The development of the Trisik Coast in Kulon Progo as a recreational area, is feasible for its natural landscape condition and its location, close to the outlet of Progo River. For this purpose, a basic survey shoal be carried out, in which case, a geomorphological survey may be a part of the survey that contributes to the study of landforms and their processes. Relevant geomorphological aspects, such as morphodynamics of the tidal zone, wind-erosion and flood hazard in the assessment of physical potential of the Trisik coast for recreation have been analysed. Aerial-and ortho-photo interpretation proved to be a useful tool in delineating landforms.

Remote sensing techniques for interpretation of landsurface physical variables related to hydrological phenomena in Lembang Area, West Java, Indonesia
Gunawan, Totok
The variables related to the hydrological processes within a watershed are considered in four categories: climate, landsurface physical processes, and output variables. Based on the properties of the image of the remotely sensed document, landsurface physical variable is one of these categories which is directly visible on the image, in a broad sense, they may vary from landform to geometrical aspect of channel. On the other hand, features that are not visible on the image, such as, underlying formation, can be deduced from related features that are directly visible.The principal methods of aerial photographic interpretation based on the pattern analysis of the landscape features and the division to the smaller features, are characterized by local pattern elements. The aims of the study are: (i) to get appropriate information about landsurface physical variables through aerial photographic interpretation, (ii) to determine and describe the interrelationship between selected landsurface physical variables and the hydrological processes.The geologic structure of•fault of Lembang area changes the landsurface physical condition, such as, surface drainage pattern, drainage density, landform and local slope, and land use. This fault and the landsurface physical changes appear on the image clearly. The development of the surface drainage is shown quite differently between

Determinants of fertility levels in Kafanchan, Nigeria
Ogbonnas, D. O.
Mamman, M.
This study is an attempt to investigate the general level of fertility in Kafanchan, a town in Kaduna State of Nigeria: The main concern is to examine the individual and group behaviour of the population with specific reference to the prevailing fertility rates.The paper examines some of socio-cultural factors that relate to fertility history, attitude related to fertility and knowledge and use of contraception.On the average, fertility in this community is high. A woman experiences a total life time fertility of 7 live-births and least one of the children die in childhood. Marriage is universal and every young man and woman aspires to satisfy this social obligation. The mean age at marriage is 17 years. A lot of importance is attached to having children, for social and cultural reasons. Knowledge and use of contraception is still very low. Government interest in population matters has been mainly restricted to population data collection for the purpose of soda- economic and political planning. These factors have a positive bearing on average family size which is relatively large.Fertility is high while mortality is low. However, as a measure towards demographic readjustment, a further reduction in the level of mortality may lead to decline in fertility. Some future planning implications of the existing fertility' evels are discussed in the light of the current population policy and development planning in the country.

The contribution of river murray tributaries to the flooding of barman forest
Bran, Leon J.
Asdak, Chay
The Barmah River Red Gum forest are part of a larger tract of such forests along the River Murray. It is known that river flooding provides an important source of water for the sustenance of these forests. The contribution of River Murray tributaries to the flooding of these forest was examined. The main stem of the River Murray above lake Hume was the single most important source. Removal of this would lead to a 55 percent decrease in forest flooding. Removal of either the Ovens or the Mitta Mitta would lead to a 30 percent reduction in flooding, while removal of the Kiewa river would lead to a 15 percent reduction in flooding. No particular tributary can be regarded as a source of extreme forest floods since all tributaries more or less act in concert. A backwater influence of high water levels at the down strewn confluence of the Goulburn and Murray Rivers leads to high water levels in the River at Barmah. However, because of the short-lived nature of such high, water levels it is unlikely that such floods penetrate very far into the forest unless they are also associated with flows in the River Murray.

Tawaghat landslide of Kuman Himalaya, India
Pande, Ravindra K.
Reports of lansdlide and sinking stc., at Tawanghat and its surrounding areas have been reported in past also with noticeable amount of loss of lives properties.A Sizable landslide accured in this region in december, 1962.During august 1977, a major landslide came roaring down the main nala (a local term used for small channels or stream) of Khela village and destroyed sheds and houses, killing 44 persons and 76 heads of cattle.About 150 acres of standing crops were washed out.Geological and geomorphological investigataion showed that a large area was dislocated at the head of the nala moving down the gradient and activating the boulder filled nala.The mass of the mountain scree that moved was perhaps resting already at a critical angle and the torrential rains had triggered the flow.In August, 1979 again a major gravitational slide of the steep mountainslopes between Rauntigad and tawaghat region had accured, seriously affecting Sinsa, gachila and Syankuri village situated on the above slipes.

Searching new strategies for managing and controlling urban land growth: a preliminary outlook on Indonesia
Yunus, Hadi Sabari
This article is a result of an intensive study of literatures concerning urban growth management. It tries to examine the specific character of existing techniques for managing and controlling urban land growth and tries to match them to the Indonesian situation. The techniques can be categorized into two major types, i.e. urban and urral (urban-rural) orientation. Indonesian .urban sprawl can be distinguished into two models, i.e. the Java and Outer Islands model. Java model is characterized by leap-frog (see for example Jakarta, Bandung, Yogyakarta, Surakarta, Surabaya) and ribbon development (see for example Padang in Sumatra, Banjarmasin in Kalimantan, Kendari in Sulawesi). The physical, social, historical background are responsible for this conditions. The urban-rural oriented strategy is highly recommended for managing and controlling urban land growth on the island of Java whereas urban oriented techniques are suggested for managing and controlling urban land development on the outer islands.

Formal rural credit for rural development in bantul district, special province of Yogyakarta : provision, use and needs
Huisman, Henk
Purbo, Ardina
After outlining the shift in interpretation of the concept and objectives of rural development since the mid-1960s, the main consequences of the new role assigned to formal credit in the desired rural transformation process are explored. Againts this background, some general characteristics of rural credit provision in Indonesia are summarized. Subsequently, the study deals with the present-day role of formal rural credit in the process of rural development in a densely populated, but internally heterogeneous district south of Yogyakarta city. The credit supply system in the area, the actual use of credit by . the house holds in the various agro-physical zones, and the appraised needs for credit in these subdivisions are presented The test con dudes with recommendations for a policy of rural credit provision which is better attuned to_ the socio-economic circumstances as present in the geographical setting of this part of central Java, Indonesia.

Rural small scale industries and regional development: A Case Study From Bantul District, Special Province of Yogyakarta
Stoffer, With
Sutanto, Agus
In last two decades, the small scale industrial sector, due to various reasons, has increasingly received attention from Indonesian policy makers. In the research area, rural small scale industrial activities play an important role, yet in a varying way. Production factors like labour and capital as well as the degree of localism are used to illustrate the differences in character.Attention is also paid to the linkages of those small scale industrial units with other units and sectors. Based on the main characteristics and the function of those rural small scale industrial activities, a distinction is made between basic and non-basic activities.A short description is given of the most important government programmes in the sphere of small scale industrial development. It is concluded that policy makers have given insufficient attention to the differences within the sector. As a result, most of the small scale industrial units are deprived of the programmes which are specifically designed for them.

Research note on the social and economic life of village people in central Java: A Case Study of Two Villages in Yogyakarta Special Region
Kuroyanagi., Haruo
This is a tentative research note of the field-work which was conducted under the title of "Research Note on the Social and Economic Life of the Village People in Central Java" in two villages in Bantul Regency, Yogyakarta Special Region for the period of one year September 1989 to March 1990.This research aims at finding the Javanese attributes of the social structure of changing village community and social and economic life of the village people. In general the spread effects of economic development and the process of social change in the rural areas are different between the village communities which are near from the cities or distant. To accomplish the research purpose more efficiently, the research study was carried out in the two villages in Bantu' Regency where is one of the typical Javanese and wet rice areas.But, in this note, objectives and methods of the research, general condition of two hamlets, composition of the households, occupations of the households'heads and farm households by owner ship status are covered. These results of the household survey in the two research sites indicate some emerging trends that the effects of economic development is stronger in the village within easy commuting distance to Yogyakarta City and that the attributes of the village people directed to money economy are also stronger there.

Moisture availability and agricultural potentialities of Mali and Niger
Serpong, E. Ofori-
One of the greatest factors limiting agricultural development in arid and semi-arid regions of Africa is lack of moisture. A country with adequate moisture has a great potential for agricultural development. It is againts this background that this paper focuses on the application of Hargreaves monthly moisture availability index classification to Mali and Niger in West Africa. The two countries are classified into moisture regions on the basis of the index and their relative agricultural potentials are assessed.

The evolving urban planning The Case of The City of Yogyakarta
Yunus, Hadi Sabari
This article is to present the changing urban plans of the city of Yogyakarta and their impacts on its physical appearance. An intensive study of extensive materials is carried out in the library and governmental institutions particularly, the regional planning board of the city of Yogyakarta. By comparing the earlier simplest plan, to the recent one, a pronounced development of the respective plan can be detected. There were five types of Yogyakarta's plan i.e. Mangkubumi's Plan, Thomas Karsten's Plan, Putuhena's Plan, Purbodiningrat's Plan and the present plan which will be reviewed here. Some conclusions are particularly directed toward the present plan because this one is not more than a synthesis of the previous plans and the inputs are expected in order to be used for further elaboration

Monitoring mangrove disappearance by remote sensing: A case study in Surabaya, East Java-Indonesia
Hartono, Hartono
Muljosukojo, Bangun
This study deals with the application of remote sensing in monitoring mangrove disappearance. Color aerial photograph scaled to 1:30.000 of 1981, numerical data of Landsat satellite taken in 1985 and SPOT satellite data of August 30, 1988 were used. The photograph was interpreted manually, while the digital analysis with DIDACTIM software was applied to the Landsat and SPOT data. Barycentric supervised classification procedure was used in clasiffing mangrove and land use classes. Key interpretation of mangrove type was obtained by field check in 1989.Two types of mangrove (Avicennia sp and mixed mangrove) could be identified both on the aerial photograph and on the SPOT data. The extent of mangrove in 1981 was measured manually, while those in 1985 and 1988 were obtained by multiplying the number of pixel (picture element) and the spatial resolution of Landsat and SPOT respectively. During seven years (1981-1988), there were 852 hectares of mangrove in the study area which have been cut.For mangrove reforestation purposes, two mangrove zonations are presented ; one is based on the salinity gradient, while the other is based on the Ciloto formula. It seems that the second zonation is quite good for the study area.

Population and environment in Indonesia
Mantra, Ida Bagoes
The present environmental situation is not compatible with our expectations. Pollution, erosion, floods and droughts have hit many parts of the world, and these disasters give us reflections on how serious are the environmental problems that befalls this planet of ours. In meeting its needs, mankind has exploited the environment to the utmost without caring about environmental conservation. Moreover, with the population explosion after the 1950s and the dependency of life upon the natural processes, the cultivated land to be inherited by future generations has gradually become increasingly barren and fertile.Efforts are absolutely necessary to check increasing population growth rates, to raise the standard of living for all people and to arouse and awareness of sustainable development policies so that a compability between development activities and environment can be achieved.

Settlements' hierarchy and centrality in Bantul District Special Province of Yogyakarta, Indonesia
Huisman, Henk
Staffers, Wim
In this article, the assessment of centrality of settlements in a district in Central Java is discussed This with a view to determine a system of service centres in the area which is functional for regional planning purposes. The study area, Bantu! District, is a densely populated area which boasts a large variety of services. The assumption is tested that both the geographical location of the district, close to the city of Yogyakarta, and the high mobility of the population, due to a well-developed public transportation system, allow for a situation whereby the hierarchical position of a settlement, based on the combination of services provided is not necessarily similar to the centrality of that very settlement, based on the number of incoming interactions. From an analysis of an intensive set of primary data, it shows that although the level in the hierarchy of a settlement largely coincides with its centrality level, the centrality level of some settlements considerably deviates from what might be expected on basis of these centres' service level.

Factors limiting industrial development in peripheral regions of developing countries: a case study of kedah state, peninsular Malaysia
Sirat, Morshidi
Many developing countries, Malaysia included, have relied quite heavily on the policy of industrial decentralization to uplift the lagging economies of their peripheral regions. In Malaysia, the Malaysian Industrial Development Authorithy (MIDA) - a federal agency - plays a major role in persuading foreign enterprises to locate in the periphery. In addition to MIDA there are plethora of state agencies which implement state industrial policy. Development officials, in their effort to attract more industries to their respective regions, work on the premise that certain locational factors are critical to investors locational decision- making process. Obviously, development officials have their own perceptions of the attractions and disadvantages of the periphery. This paper (a) examines whether the officials have a good grasp of the industrialists dominant motives for selecting Kedah as production location, and (b) discusses the implications for industrial development if officials assumptions do not concur with industrialists real reasons for selecting Kedah location.

Routing model of sediment yield for a representative Himalayan drainage Basin, India
Pande, Ravindra K.
For a large watersheds sediment yield can be more accurately estimated if the large watersheds is divided into sub-watersheds to compensate for non-uniformly distributed sediment sources. The effect of drainage basin hydraulics can be included by routing the sediment yield from sub-watersheds to the large watersheds outlet Sediment routing increase prediction accuracy and determines individual watersheds contribution to the total sediment yield.

Some factors attracting new arrivals in the urban fringe areas: A Case Study of Sinduadi, Mlati, Sleman, Yogyakarta, Indonesia
Yunus, Hadi Sabari
In the discussion on any urban development, one can not neglect the so=called centrifugal and centripetal forces causing the flow of either people and functions from and to the inner parts of the city or the fringe. These two forces constitute the dynamic doers for the development of the city concerned. One of the aspects of urban development is a change in physical performance of the city itself and the sprawling process of urban features in the surrounding countrysides. The study is carried out in one of the portions of the fringe areas of the city of Yogyakarta that is receiving many arrivals either from the inner parts of the city or from the more remotely located areas. The discussion is merely focussed on one of these broad scopes, i.e., movement of people either coming from the inner parts of the city and coming from the more remotely located hinterlands. One of the subdistricts located next to the municipal boundaries is chosen as a case study and the respondents are selected randomly among new migrants in the last ten years. The result shows that nine reasons constitute attracting factors to the fringe areas. Centrifugal movement is predominated by those who are looking for more spacious placelspace for living and the lower price of laud whereas centripetal movement is predominated by those who are approaching their place of work.

Rural basic service development: An Operational Approach
Sutanto, Agus
Approach on the study or rural service development is often both development indicators are interchangeable. However, the two studies are closely related and could contribute one to another. A confusion also exists in the setting up of the concepts of social service and economic service function. As such, the study of service development should have a great care of the study implication in which sectoral action planning should follow-up.

The influence of population mobility on human settlements
Lado, Cleophas
This paper examines some of the characteristics of world's population mobility, cultural environment and changing societies. Some of the national and international problems associated with population data collection and enumeration are explored including transient and temporary population movements. In analyzing population mobility and demographic transition, Zelinky's hypothesis is used as a conceptual framework applicable in both Developed and Developing countries. The findings of the study focused mainly on some of government policies and implications essential for rural-orientated and urban-orientated development programmes. It is emphasized that to achieve some of the socio-economic development objectives in any nation, it is important to have a comprehensive understanding of all the processes of mobility to match the various government policies of the redistribution.

Hydrological properties of oak and pine forests in Central Himalaya, India
Pande, Ravindra K
In general, hydrological cycle in forested areas is a complicated phenomenon. In Himalaya the vegetative cover plays a vital role in determining several hydrological characters. For the experimental study of oak and pine forests hydrology, two representative basins are selected in the Central Himalaya. After evaluating the hydrological properties of oak and pine forests, it is decoded that both the vegetation types have different hydrological characteristics. However, with the destruction of vegetation and top soil, rainfall quickly runoff as stormflow instead of soaking into the soils.

Implications of rainfall for agricultural and urban development of Eldoret, Kenya
Sarpong, E. Ofori-
This paper examines the role of rainfall in the urban development of Kenya. The rainfall characteristics have been analysed and their influence on agricultural and urban development assessed. It is noted that since Eldoret is one of the rapidly expanding towns in Kenya located in highly potential agricultural region, variability of rainfall and drought can seriously affect urban development as farmers in the hinterland will abandon their farms and migrate to the town thus creating food shortage. Secondly, in times of drought, the water supply problems in the town will be exacerbated as it depends on surface water source. The tempo of rural-urban migration will be speeded up and this will create more socio-economic problems.

Some Notes on Groundwater As A Domestic Water Supply of The Yogyakarta Municipality
., Sudarmadji
groundwater, water, volcane
Water supply in Yogyakarta municipality is mainly originated from two main sources, the pipe water and groundwater. The pipe water which is operated by the local drinking water authority does not suffice for the water demand of the people in the city. Tire second source is groundwater, which is used by most people in the city by traditional system. The aquifer of the Yogyakarta which consists of volcanic materials erupted by Merapi volcano is fairly good, however the expansion of the city area toward the northern and north eastern area may reduce groundwater recharge. The rapid growth of population and other city facilities such as hotels may cause groundwater supply to decline. Groundwater quality in certain area may subject to pollution by domestic wastes, assigned by the high content of chemical substances such as iron and sulphate, besides high content of coliform bacteria, and nitrite. Heavy metals were undetected in the groundwater of the area

The Use of Spot Image for Mangrove Inventory in Cimanuk Delta West Java, Indonesia
., Hartono
This study deals with an application of SPOT satellite data for mangrove forest inventory in Cimauuk Delta West Java (Indonesia). Mangrove of the area (7100 Ha) has been gradually decreasing by human pressure especially for fisheries purposes. In fact, mangrove here is a result of afforestation since1960, with Rhizophora mucronata and R. apiculata as main planted species. Other species are Lunmitzera racemosa, Excoecaria agallocha, Bruguiera gymnorhiza and Avicennia which grow naturally. SPOT data were digitally analysed using Didactim software. A color composite image was analysed. A barycentric supervised classification and textural analysis were applie.d. As an intermediate data, infrared color aerial photographs at 1130,000 (1981) were interpreted manually.At least two mangrove types of mangrove could be identified from the SPOT image. Dense mangrove was found in Petak 7, Petak 8, Petak 9 and Petak 12. In the other Petaks, mangrove were less than 20% of their surface. Mangrove of Rhizophora in 26 Petaks covered 290 Ha only.

The Volcanoes of Indonesia And Natural Disaster Reduction
Verstappen, Herman Th.
Indonesian volcanism is related to the subduction (genie zones of the Lido-Australian and the Pacific-Philippine plates at the contact with the Asian plate. Rows of volcanoes perpendicular to the plate movement point to steepening of the subduction zone. with time. Strafo volcanoes and also ignimbrite plateaus associated with socalled "volcano-tectonic" depressions Of deep-seated faiths are major features. •Fluvio-volcanic flows and slopes arc common due to the humid tropical climate. Large volcanic landslides and debris flows causing rupture of crater or caldera rims and the collapse of slopes also arc important volcanic geomorphological features.The role of geomorphological survey and the use of aerospace technology in volcanic hazard zoning is emphasized

The Dilemma of Food in Africa
Kaloko, Franklyn R.
Although over 70 per cent of the labour force is engaged in agriculture, Africa is loosing the capacity to feed itself. Drought, a fast growing population, widespread deterioration of the countryside, as well as a chronic undereinvestment in agriculture, have all contributed to declining yields and a vicious cycle of poverty from which the peasant farmer and African countries have increasingly found it difficult to escape.The need therefore is most urgent for African governments to reexamine their food and agricultural policies to tumble them provide more food for their growing population. Encouragement of large and Medium scale commercial farming, land reform, environmental management, reduction of population growth, improvement in storage and transport facilities as well as pursue political stability and a cessation of the violent conflicts that have characterized the continent, will reduce the food problem in Africa.

Contingent Valuation of Watershed Protection in Nigeria: A Case Study
Olokesusi, Femi
The search for appropriate methods for valuing natural resources and monctising externalities is a pressing problem facing many governments, particularly those of the developing countries. While the Nigerian government allocates 2% of its annual gross income for ecological damage restitution (The Ecological Fund), experiences arising from incessant disputes in the oil producing areas, fishing sites, increasing incidence of soil erosion and flooding and other environmental problems, all point to the need to supplement the Ecological Fund with money from other sources.Most environmental degradation resulting from mithropogenic prococcrs in water resource projects can be ascribed to the "common property" perception of water and associated natural resources. Moreover, in deciding which environmental regulations, and water resource projects and programmes are desirable or otherwise, it is imperative to weigh the negative socio-economic impacts, againts the very real beneficial effects. Such a process will entail better monetary quantification of the cost-benefit analysis of the projects and programmes, particularly during environmental impact assessment process.This paper focusses on the use of the willingness-to-pay (WTP) approach for determining the amount of money that people in selected large-scale irrigation and dam project areas in the Sudano-Saludian zone of Nigeria are willing to forego for the sake of environmental protection in the watershed. After a general description of the problems and approaches to valuing and monetising environmental resources and their protection, the details of the study findings and policy implications are discussed.

Spatial Determinants of Import Traffic Distribution At Port Harcourt (Nigeria)
Inyang, Soddy I.
This paper highlights the result of a study carried out to examine the Geographic determinants of import traffic distribution at the Port Harcourt Port. A substantial aspect of the study involved building a regression model to estimate import distribution from the Port. The import function was specified in log-linear form. The adequacy of the model was then tested; this, involved statistical experiments to obtain the R-squared, as well as t and f values. Further test on the adequacy of the nwdel was conducted through diagnostic exercises designed to check for inulticollinedrity and heteroscedasticity, in the data used. Results obtained show that road distance and manufacturing industries are significant Geographic determinants of import Cargo distribution at the study Port. It is therefore important to lake the two variables into account in any policy or planning exercise at Port Harcourt Port.

Indonesia's cultural economy: an economic geography using two secondary data sources
Gibson, Chris
Wiszniewski, Iwona
Indonesian Culture Economy, Cultural Commodities, COMTRADE Database
Economic geographers have become increasingly interested in the importance of the 'cultural economy' to cities and regions, but rarely have results been sought or discussed for Southeast Asia or nations in the developing world. This article responds to this lacuna by charting an economic geography of cultural production in Indonesia, examining two sources ofpublicly available data: the United Nations Statistics Division's COMTRADE database of trade statistics, and DISb2b Indonesia (a commercial database of business location details in Indonesia). Results are discussed for the period 1996- 2002, for which reliable data are available. While both sources are limited (and such limitations are discussed here), they provide enough insight for some conclusions about the character of 1ndonesia's cultural economy to emerge. In contrast to studies of cultural economy in overseas contexts, Indonesia's culture-related exports are dominated by emphasis on hardware and manufacturing output, rather than intellectual property or 'symbolic' content. In keeping with overseas examples though, the geography oflndonesiak cultural economy displays high levels of metropolitan primacy. Results suggest that theories of cultural economies must be re-shaped to include consideration of regional and international flows, in addition to locally-unique class, cultural and economic dynamics in particular cities and regions.

Principal component analysis for identifying period of seasons in Indonesia
Condro Kirono, Dewi Galuh
Principal Component Analysis, Season period, Indonesia.
The seasonal variability of Indonesian rainfall is almost entirely controlled by the Asian monsoon and so displays two distinct seasons, i.e. wet and dry seasons with transition periods in between. The onset of the monsoon varies with places, therefore, when dealing with seasonal rainfall, different researchers/authors have different way referring to the seasons. Hence, one definition may not be appropriate for all places. This problem creates a necessity for identifying the period of the season so that it can be used for Indonesia as a whole.This paper examines the spatial variation of the seasons over the Indonesia region and demonstrates the application of Principal Component Analysis (PCA) to solve the above mentioned problem, namely to identify the period of the seasons in Indonesia as a unity. The analysis is performed using monthly rainfall data from 63 stations spread across the country covering the period of 1947 to 1999 (52 years).The results support the fact that the wet season onset starts early in the northwestern part of Sumatra and propagates eastward and southward. It is not surprising if the north-western part of the country experiences a longer wet season than the east-northern part does. It is also shown that PCA is a useful tool for identifying the period of the season in Indonesia. Through the analysis, it is found that there are three types of rainfalls which have important influence on the year to year variation of the annual rainfall, i.e: the wet season (December to March), the dry season (May to September), and the dry-to-wet transition (October to November).

growth pattern and the industrial development of the lagos region, nigeria
Ajayi, Dickson Dare
Industrial development, industrial spatial pattern.
This paper examines the nature, growth and spatial pattern of industries within the Lagos Region. Industrial activities in this region grew progressively over the year from mere brickwork, palm oil mills, printing press, soap factory, and metal container factory to capital intensive manufacturing. Indeed, the number of industrial establishments increased from 122 in 1962 to 637 in 1993. Lagos developed into Nigeria's leading industrial center; especially following the expansion in its service and administrative sectors. Whereas, chemicals and pharmaceutical; and basic metal, iron and steel and fabricated metal products industry groups dominate in industrial scene, wood and wood products (including furniture); and non-metallic mineral products are rare. The spatial pattern shows that industrial establishments vary amongst the industrial estates/areas, and also among the industry groups. Ikeja/Ogballsheri industrial estate/area dominates the industrial scene.

The present and the Archaic River Valley morphology and groundwater condition in the Plaosan Temple complex Central Java-Indonesia

Edy Y, J. Susetyo
Fauzi, Imam
S, Didik
R, Wahyu Broto
The Plaosan Temple which was built during the eighth and tenth century AD is one of four temple complexes in the Prambanan area, Central Java-Indonesia. On going excavation in the temple complex discloses the occurrence of canals along the outer fences. The canals are eight meters wide and four meters deep. This article aims at reconstructing archaic river course and groundwater condition due to the construction of the canals. Aerial photo interpretation, excavation, ground water level measurement and valley morphology measurement reveal an anomaly of the nearest river in the temple complex. The river had seemingly been bypassed south-eastward to its tributary just before entering Plaosan Temple complex. Groundwater level dropped and its flow direction changed from nearly southward to south-eastward direction. These phenomena indicate that the canals were groundwater-discharged canals.

Vulnerability assessment of groundwater to contamination using drastic method: Study in Ngemplak, Ngaglik and Sleman Districts of Sleman Regency, Yogyakarta Special Province
Widyastuti, M.
Vulnerability, Groundwater, Contamination
This research is based on the assumption that the physical environ-ment may provide some degree of protection to groundwater against the natural and human impacts, especially with regard to contamination entering subsurface environment. Study on groundwater vulnerability to contamination .become important. It can be used as a valuable planning tool to overcome the problem of groundwater quality due to uncontrolled land development and undesirable activities. The aims of this study are : 1) to study the distribution of DRASTIC parameters, which are depth to water table, rainfall, aquifer media, soil media, topography, impact of vadose zone, and conductivity; 2) to analyze the vulnerability of groundwater to contaminationThe stua5, was performed by weighting and rating method of DRASTIC parameters. The degree of groundwater vulnerability to contamination is depicted in DRASTIC Index. DRASTIC Index is determined by overall sum of all multiplication between score and weight number ofeach parameter. Data manipulation and data analysis were all performed using Geographic Information System (Arc/View version 3.2). The vulnerability map of groundwater to contamination has been generated using overlay operation of DRASTIC parameters.The result showed that DRASTIC index varies between 73 to 172 intervals. Hence, the indexes were categorized into five level of groundwater vulnerability, namely invulnerable (73-92), low vulnerable (93-112), moderate vulnerable (113-132), high vulnerable (133-152) and very high vulnerable (153-172). It is found that more than 50 % of the study area is covered by high and very high vulnerability of groundwater to contamination. The vulnerability level and its area as follows : vo• high 92974.63 ha or 28.18%), high (7049.86 ha or 66.79 %), moderate (529.90 ha or 5.02 %). low (0.148 ha or 0.0014 %) and invulnerable (0.003 ha or 0.0003 %).

The challenges of urban management in Uganda
Mukadasi, Buyinza
Nabalegwa, Muhammod
Urban area, population, rural districts, government policies
The urban areas in Uganda are increasingly getting under pressure from a rapidly growing population. The challenge of a growing population has coincided with the central government policies that favour rural districts more than urban areas.The challenges that the urban areas face include the problem of two populations (the night and day time); high generation of garbage; poor revenue base; a growing informal sector; growing squatter settlements; deterioratingwater quality; and the limited institutional capacity to provide the required urban services. Financial resource mobilisation has been inadequate due to high costs oft= administration, low institutional capacity for enforcement, and a general public apathy to tax payment.

Yunus, Hadi Sabari
Harini, Rika
rice fiel4 land use conversion
The research was conducted in Yogyakarta Special Province. The main objective of this research is to find out the main factors influencing the change in agricultural land use especially rice field. The data used in this research is time series from 1980 to 2000. They were obtainedfrom several institutions such as: Central Bureau of Statistics (BPS), National Agency of Land Affairs (BPN) and Department ofAgriculture (Dinas Pertanian). Descriptive analysis and statistical test were performed against those data to find out the influence of geographic factors i.e. the population growth, the road development and the extension of built up area on the change in agricultural land use especially rice field. Distributed lag model is used to analyze the effect of road's length on agricultural land use change. The level and magnitude of relationship between areas of agricultural land use change and built up area, number of people and road length are calculated using linear regression.The research shows that the period of 1980 - 2000 in Yogyakarta Special Province has indicated very significantly the increase in population, the development of road and the extension of built up area. For the time being, agricultural land mainly in Sleman Regency, Bantul Regency and Yogyakarta Municipality has decreased. Sleman regency performed the largest decrease of rice field and followed after then by Bantul regency and Yogyakarta Municipality. The regency of Kulon Progo and Gunung Kidul have experienced reverse phenomenon i.e. the increase of rice field during this period. Individually or simultaneously, three variables used in this research (number of people, road's length and built up area) have significantly influenced the agricultural land use.

a deterministic model for predicting water yield from two different watersheds
Sudira, Putu
deterministic mode4 watershed, water yield, soil water zone
This study was conducted in Pogung-Code sub watershed and Pulo-Opak sub watershed from 1993 to 2002. A deterministic model developed by Haan (1972) was used to determine the amount of water yield from watersheds. The model consists offour parameters, namely: (0 maximum rate of seepage from the soil water zone in mm per day (S), (ii) maximum soil moisture less readily available for evapotranspiration in mm (C), (iii)fraction ofseepage from the soil water zone that becomes runoff(F), and (iv) maximum infiltration rate in mm per hour (f.).The inputs required by the model were the daily rainfall and the estimated potential evapotranspiration which was computed using Penman method. Streamflow records for 10 years of Pogung-Code sub watershed (2,801.77 ha) and Pulo-Opak sub watershed (4,856.37 ha) were used to test the validity of the model. The parameters obtained for Pogung-Code sub watershed were: S = 0.70 mm per day, C = 112.32 mm, F = 0.63, and- 5.38 mm per hour, meanwhile for Pulo-Opak sub watershed were: S = 2.33 mm per day, C = 86.72 mm, F --- 0.26 and f = 5.68 mm per hour.The final test of the adequacy of the model lay in a comparison of observed and simulated runoff The comparison showed that the observed and simulated runoff values are not significantly different. This was based on the results obtained from statistical measures to test the model. The model did a better simulation in the smaller watershed (Pogung-Code sub watershed) than in the larger one (Pulo-Opak sub watershed).

The spatial patterns of Korean investments and their effects on regional development in Indonesia until 1998
Rijanta, R.
Korean investment, Indonesia, regional development
Korean investment in the ASEAN Region has grown tremendously during the last three decades, following the importance of Japanese investment in the same region. This is partly due to a favorable domestic growth in the Korean economy as stimulated by a successful agricultural reform and rural development on which industrialization takes place. Korea transformed itself from an underdeveloped, agricultural-based economy, into an industrialized country in Asia only within a very short span of time.This paper is aimed at assessing the spatial patterns and effects of Korean investment in Indonesian regional development before to the crisis. To achieve this general objective, an account on the general pattern of Korean investment is discussed from global level, Asia, ASEAN and Indonesia. Finally, an account for the spatial patterns and effects of Korean investment on regional development in Indonesia is presented.The paper is based on secondary data analysis. Data are gathered from various websites related to foreign investment in Indonesia as well as publications of various government organization for the spatial patterns and impacts of Korean investment. Data are analyzed using a simple descriptive statistics and thematic mapping.The research reveals that Korean investments in the world are mainly directed to USA, Europe and Southeast Asia. Southeast Asian Region has been the most important destination of Korean investment in the last three decades due to the availability of cheaper labor force, abundant natural resources, and favorable climate for investment and with little exception political stability. Recent investments are also directed to more capital intensive and more advance technology, thus facilitating the transfer of technology_ The distribution of Korean investment in Indonesia as any other foreign investments tends to be clustering in the surrounding areas of Jakarta, known as the Bogor, Tangerang; Bekasi (BOTABEK) Region where some 65 percent of foreign investment is located.. The effects of Korean investment on regional development at national level in Indonesia are very limited, but there is a substantial effect on the regional production structure, economic growth and employment generation at local-regional level, more especially in the main industrial agglomeration of the BOTABEK Region.

Application of inverse modeling technique to describe hydrogeochemical processes responsible to spatial distribution of groundwater quality along flowpath
NugrohoAdji, Tjahyo
Groundwater, Inverse Model, Saturation Indices, Mass Balance
The main objective of this research is to define the mechanism model of chemical reactions, which are responsible to the spatial distribution of water quality along flowpath using inverse modeling technique. in addition, the Saturation Indices (SI) analysis was used to characterize the effect of geological condition toward dissolved constituent within the groundwater: Moreover, Mass Balance Modeling code was employed to describe the stoichiometry and hydrogeochemical processes along flowpath.Field survey was carried out in order to obtain the data of hydraulic head and electrical conductivity to construct flownets and tentatively illustrate the spatial distributions of shallow groundwater quality. Next, the flow line was applied to define the sampling position of groundwater and aquifer mineral. Laboratory analysis was conducted to identify the main phases and constrains of dissolved constituent within the groundwater. Afterwards, the application of NETPATH 2.1.3 and Phreeqc Interactive 2.8 for Windows software aid to model the Mass Balance Calculation in order to account the prevailing hydrogeochemical reactions.The result shows that firstly, the aquifer within the research area can be grouped into several aquifer systems (i.e. denudational hill, colluvial plain, alluvial plain, and beach ridges) from recharge to discharge which generally have potential groundwater resources in terms of the depth and fluctuation of groundwater table. Secondly, flownets analysis gives three flowpaths that are plausible to be modeled in order to describe their hydrogeochemical reactions. Thirdly, the Saturation Indices (SI) analysis shows that there are a positive correlation between the mineral occurrence and composition and the value of SI from recharge to discharge. In addition, The Mass Balance Model indicates that dissolution and precipitation of aquifer minerals is dominantly change the chemical composition along flowpath and the rate of the mass transfer between two wells shows a discrepancy and be certain of the percentage of the nature of aquifer mineral. Lastly, there is an interesting characteristic of mass balance chemical reaction occurs which is the entire chemical reaction shows that the sum of smallest mineral fmmol/litre) will firstly always totally be reacted.

Geomorphological mapping of the San Lorenzo area Sant'arcangelo region Southern Italy
Marfai, Muh Aris
Geomorphologieal mapping, San Lorenzo area
The study area is located in the Sant'arcangelo region, Southern Italy. The area was developed from late Pliocene to middle Pleistocene in the southern part of the Apenines chain. It has also been defined as a piggy back basin filled with siliciclastic deposits, controlled by sedimentary tectonic activity.This article aims to identify the geological condition and generating geomorphological map for San Lorenzo area using aerial photo (scale 1:15000) and Panchromatic SPOT image (Scale 1:66000). Image interpretation was also done to identify morphological, structural and processes.The Sant'Arcangelo region is composed of 4 cycles both marine and continental in origin, all deposited on different environments: The Caliandro, Agri, San Lorenzo and Sauro cycles. The study area consists of Sauro and San Lorenzo Cycle. Sauro Cycle is Comprises of three heterotrophic units deposited in sintectonic discordance over the Agri cycle. San Lorenzo Cycle lying in unconformity over the precedent cycles is consisting of three units, namely conglomerates on the base part as well as on the top part of the sequence, and silty clays in the intermediate part. They form a syncline structure which ax has a NW-SE direction. The main structural features are represented by the San Lorenzo syncline and the Alianello fault. The San Lorenzo area has three principal origins: alluvial, denudation, and structural. Due to the geological-tectonic complexity, the structural landform is normally found as structural denudational landform. San Lorenzo area comprises of 41 landform units, namely 3 units of alluvial landforni, 26 units of denudational landform and 11 units of structural denudational landform.

Hydrological Implication of Bamboo And Mixed Garden In The upper Citarum Watershed
Asdak, Chay
runoff, soil erosion, bamboo and mixed gardens, upper Citarum watershed, West Java
The assessment of important factors affecting runoff and erosion was carried out by collecting runoff and soil loss from four runoff/erosion plots. The runoff/erosion plots were set up in sloping areas of about 40% slope in the upper area of Ciwidey sub-watershed (upper Citarum watershed), West Java. The plots (6 x 10 m) were established in the following four sets of conditions: bamboo plantation, mixed garden, small shrub, and agricultural field with different species and stand structures. After 20 rainfall events, a treatment in the form of removing undergrowth and litter were applied to bamboo and mixed garden plots. The result of this before and after treatment are the following: runoff from bamboo plantation was increased from 0.40 to 1.02 litre/m2 and erosion was increased from 1.47 to 11.65 gr/m2. While the runoff and erosion in mixed garden were increased from 0.36 to 1.65 litre/m2 and from 1.36 to 10.88 65 gr/m2, respectively. When this compared to the runoff and soil loss in the agricultural plot, the soil erosion is much higher, 50.5 gr/m2 (about 50 times higher). Stand/canopy structure appeared to be the important factors that determine the magnitude of soil erosion. While the role of these factors were less significant compared to rainfall in determining the magnitude of runoff.

groundwater withdrawal, GMS version 3.1. software; transient simulations
Simulation of groundwater withdrawal has been conducted with a groundwater modeling system (GMS) version 3.1 software at a regional scale. The simulation was conducted from ten year groundwater withdrawal data in Merapi Aquifer, DIY, Indonesia, for two assumed scenarios, with an emphasis in Sleman area. The result for the ten year groundwater simulation was conducted spatially distributed in the Merapi Aquifer after the steady state simulation was reached. With two different types of transient simulations, the total withdrawal of 28,968 m3/day for the whole Merapi Aquifer is still acceptable with caution, as long as the . recharge is not decreasing. However, less withdrawal as the existing withdrawal condition is recommended until local site investigation is sufficient to avoid the danger of overdraft.

Long Term Rainfall Trend of The Brantas Catchment Area, East Java
Aldrian, Edvin
Djamil, Yudha Setiawan
spatial rainfall trend, Brantas, EOF, climate change
Spatial and temporal rainfall analyses of the Brantas Catchment Area from 1955 to 2002 based on 40 daily rainfall stations has been performed. To identify the climate pattern for the last five decades, we used the Empirical Orthogonal Function (EOF) followed by the Fast Fourier Transform. By using EOF, we found the monsoonal pattern as the most dominant, which explains about 72% of all variances. The interannual pattern shows a negative trend of the monsoonal strength. From the monthly isohyets for each decade, the rainfall amount appears to decrease significantly during the last five decades, indicated by wider low rainfall amount areas and the orographic effect is detected, indicated by always greater amount in highlands. From rainfall data in mountain and coastal areas, dry periods had been increasing, mainly in lowlands. Thus, the continued imbalance of the dry and wet period is one cause of the monsoonal strength decrease during the last five decades.

small industry, technology transfer, inter/intra-enterprise, dessert/palm tree industry
In last decade, the small industrial sector has increasingly received attention from Thai policy makers. This study investigates the relationship between small industries and community in rural area in term of technology transfer. In the research area, knowledge and experience gathered from workplace as an employee and family businesses are the core resources to establish and run busineSses. Technically, technology transfer is divided into 2 characteristics; intra-enterprise and inter-enterprise. Intra-enterprise technology transfer comes from employers to employees, emphasizing production development. Beside, technology transfer of inter-enterprise has two directions. Firstly, direction points from the entrepreneur to material suppliers aiming to secure raw material quality. Secondly direction points from consumers to the entrepreneur aiming to put a great emphasis on product development, quality control and management.

geomorphological approach, natural resources, regional zoning, Merapi volcano
Geomorphologial approach can be used as the basic for identifying and analyzing the natural resources potentials, especially in volcanic landscape. Based on its geomorphology, Merapi volcanic landscape can be divided into 5 morphological units, i.e.: volcanic cone, volcanic slope, volcanic foot, volcanic foot plain, and fluvio-volcanic plain. Each of these morphological units has specific characteristic and natural resources potential. Based on the condition of geomorphology, the regional zoning can be compiled to support the land use planning and to maintain the conservation of environmental function in the Merapi Volcanic area.

social facilities, rural development index, Jos Plateau - Nigeria
The study has measured the levels of social facilities provision in the rural areas of the Jos Plateau Region of Nigeria. Over 60 dependent and independent variables were employed in determining the rural development index (RUDEVI). Social sectors covered include health care, educational, water supply, rural roads, places of worship and other general welfare infrastructure and services. The various levels of rural development indices of the 86 communities studied were subjected to analysis of variances (ANOVA), correlation and regression using population size as the focal variable. It was found that population is not a major factor used in the sitting of social facilities in the rural areas of Jos Plateau, which is not supposed to be the case.

Boicultural diversity, global economic system, holistic development
The emerging concern in the last few decades for conserving 'diversity' is an impetus to conserve not only the whole spectmm of biota i.e. the total sum ofgenes, species and ecosystems but also indigenous culture, traditions, spiritual beliefs and values. This phenomenon is named Biocultural Diversity, which is a synthesis of both Biological Diversity (biodiversity) and Cultural Diversity. 1980 's was considered the decade of biodiversity, 1990's that of cultural diversity and 2000's a new field of Bio-Cultural diversity. In the first half of this paper the. interrelationship and interdependence between biodiversity and cultural diversity is discussed and in the second half how the modern global economic system is engulfing this diversity of life, knowledge, cultural heritage and practices areanalysed The global distribution and patterns of biodiversity coincide with that of cultural diversity, therefore if languages and cultures disappear due to global pressure of homogenization we also lose knowledge about our environment leadingto biodiversity depletion~ It is quite noticeable that the countries with peoplespeaking largest number of languages; and countries with greatest number of traditional livelihoods and indigenous communities obviously have the greatest biological diversity. Thus only a sustainable approach can bridge the gap between modern visions of human beings and traditional cultural aspirations thereby ensuring holistic development.

Misconception Of Run-Up Definition And Its Implication To Tsunami Risk Assessment A Case Study In Pacitan Coastal Area, Indonesia
Mardiatno, Djati

Stotter, Johann
Tsunami, run-up, misconeption, water height, tsunami risk, java, Indonesia
This article aims to build the similar understanding of run-up concept and to review the "map of t,'}iinami risk analysis in Pacitan" released by Balai Pengkajian Dinamika Pantai (BPDP)-BPPT Indonesia. We also propose similar understanding of risk definition related to the natural hazards, such as tsunami. The investigation used comparison method between 2 maps, i.e. tsunami risk map by BPDP and our tsunami risk map. Based on the comparison result, we found a misconception of rim-up in the tsunami risk map produced by BPDP. There is no differentiation between run-up and water-height over the land. It should be revised to avoid it from the incorrect rim-up definition. We also found if it was also mentioned as a "map of t.\imami risk analysis" while the analysis result was not performed in that map. Therefore, it is necessGlY to understand the run-up concept and risk concept first prior to map those phenomena.

The Use Of Remote Sensing For Mangrove Ecosystem.Monitoring In Segara Anakan Central Ja Va
Hartono, Hartono
remote sensing, mangrove forest, ecosystem degradation
The paper deals with an actual condition of mangrove ecosystem in Segara Anakan Central Java by analysing them from remote sensing satellite image such as SPOT XS and Landsat 1M recorded in between 1981 and 2003. Digital and manual image analysis were applied Field checks were conducted in 199 3 and in 2005.The result show that three aspects of mangrove ecosystem can be studied from the remote sensing data, i.e. mangrove zonation, land cover changes and mangrove physical ecosystem changes. In mangrove zonation, it showed that three to four zones in mangrove forest zonation can be identified by satellite digital data analysis, especially in accretion areas. Mangrove of these areas actually suffers from human pressures, mainly for fishery and agriculture activities, and environmental changes. Lagoon morphometric decreased considerably and its influenced the existence of the mangroves. Mangrove extend in Segara Anakan, the mangrove forest covers 8600ha in 1987 and 7500ha in 1998, and in 2008 it decreased considerably. The lagoon of Segara Anakan undergoes to be disappeared by sedimentation processes from its hinterland In consequence mangrove ecosystem in the region is in dangerous condition

Land Conservation Initiatives Around MT. Elgon National Park, Eastern Uganda
Buyinza, Mukadasi
Land Conservation, Farmers, Mt Elgon, Uganda
The goal of this paper is to provide an investigation of the land conservation strategies adopted by farmers to control land degradation around Mt. Elgon National Park, Uganda. Primary data were obtained through household survey conducted in Mutushet and Kortek parishes, Kapc.horwa district between June to December, 2003. The differences between adopters and non-adopters of land conservation practices in terms of contact with extension workers, tribe, size of productive family labour, membership to farmer organization, education level, and participation in communal land management activities and frequency ofnatural hazards on private agricultural landfj were examined Farmers have increasingly adopted different structural measures like terraced farming, construction of waterways, check dams, retention walls, and gull control. Similarly, they have also adopted different biological measures including alley cropping, bamboo plantation in gullies, mulching and applied organic and inorganicfertilizers to control land degradation. However, farmers have not been able to control land degradation to a great extent due to relatively weak technological backup by concerned agencies. It was concluded that severity of land degradation is higher in the parishes with traditional farming methods because farmers are not provided with the necessary technical advisory services.

Micro-Environmental status of a dissected highland (College Tilla) of Agartala city, North East india
Dey, Sudip
Tilla, Micro-environment, Urbanisation, Geomorphology, Plant coverage, Micro-level slopes
This paper assesses the present micro-environmental conditions of a dissected highland", College Tilla of Agartala city of North-East India. Geomorphologically Agartala city is located in a part of the basin of R Haora which consists of two main geomorphic units namely dissected high lands or tilla lands and adjacent flat alluvium lands. The elevated geomorphology of the tillalands play important role for the development and preservation of typical high landenvironment and rich ecological resources in some pockets of flat alluvium of R Haora basin for long time. Since the urban activities started on College Tilla only during early 2dh century the variation of flora and fauna of the tilla land is still.remarkable. During the recent period rapid extension of Agartala city causes theproblem of geomorphic degradation and affects the natural environmentalcondition of the area. Due to the construction of the buildings, roads, boundaries, water pipe lines etc the dense vegetation cover is removed rapidly and as a result of that now soil erosion and medium size land slides are becoming very commonfeatures in the city. Besides that the ecology of this area is now under serious degradation due to desperate human interventions on the tilla lands of Agartala City

Application Of Water Table Fluctuation Method To Quantify Spatial Groundwater Recharge Witidn The Southern Slope Of Merapi Volcano, Indonesia
Adji, Tjahyo Nugroho
Water table fluctuation, Groundwater recharge, Merapi Volcano
The southern slope of Merapi Volcano plays a significant role to Yogyakarta Municipality groundwater resources. Groundwater recharge, herein meant as the effective precipitation that infiltrates into unsaturated zone andpercolates to water table after exceeds the soi/field capacity, is the main subject in this article. The objective of this research is to apply WTF method to spatially define the groundwater annual recharge. Four wells are selected to represent some geomorphologic units. Then, four A WLR installed to record the yearly shallow groundwater table fluctuation. In addition, WTF method requires groundwaterfluctuation and specific yield data. The rate of groundwater recharge in every well confirms the varying value. However, it seems that geomorphologic unit may be principally control to the time series variation of shallow groundwater jluctuationthat results in groundwater recharge characteristic. The volcanic slope unit (above 600 m as!) has the lowest water table fluctuation indicates the resistant comportment to the annual rainfall. Ihis unit is characterized by the relatively high magnitude of recharge of approximately 4270 mm/year.

Analysis of Intra-Urban Traffic Problems in Nigeria: A Study of Lagos Metropolis
Bashiru, A. Raji
Urban Commuters, Metropolis, Traffic Congestion
Problem of trqffic congestion is common in most big cities of the world.Drivers of privately owned vehicles and passengers may experience substantially loss of time while in traffic jam. Also, solutions to causes of this menace are well documented in the literature. In spite of the vast studies and applied measures toreduce these jams, the problem seems to be growing stronger on daily basis. One ofthe o~jectives of this study is to examine (l the intensity of traffic congestions are similar along the routes, and on d(fJerent days of the 'week within the ci~y of Lagos.The paper also examines the traffic pattern along ten selected routes within five metropolitan areas in the state. The study shows that 57% of the commuters and motorists in the study area do spend an average of 30 to 60 minutes in congestedtraffic. Three peak periods of traffic congestion were recognized. Indiscriminateparking, road side trading, flooding, existence o.fpot-holes on these roads, vehiclesbreaking down and absence o.f traffic light at some road intersections are some ofthe identified major causes of traffic congestions. Mondays were recognized as the most congested day by 57% of motorists and commuters interviewed. The analysis o.f variance result shows insign(ficant variation in traffic congestion among the fivelocal government areas. However, the observed spatial and temporal pattern o.l vehicular traffic congestion enabled us to suggest possible measures for the reduction of traffic congestion within the metropolis.

Financing Public Transit Systems In Kuala Lumpur: Challenges And Prospects
Kiggundu, Amin Tamale
large cities, public transit, Kuala Lumpur, funding
Prioritizing public tramjport in large cities requires huge amount of money.In Kuala Lumpur for example, public transport services are relatively poor and inefficient due in part to the inability by the major operators to mobilize ample investment capital. Besides, the new funding systems such as the Public Transportation Trust Fund (PTTF) may not be able to solve the problem because they are still unclear and incoherent. Other key challenges are: lack of a pro-transit policy. rapid motorization. urban decentralization as well as dependence on farerevenue and banks to fund new investments. CrucianF. due to the poor design of private rail concessions, government intervention has been inevitable.

Theoretical Development of Urbanization Study in the Third World and It's Relevance on Rural Urbanization Research
Widyatmoko, M.R. Djarot S.
urbanization studies, rural urbanization
At least.. there are /11.'0 points of concern in the urbanization studies, i.e. to see urbanization as a process of structural change of rural population (and areas) and to give attention to the interrelationships (in terms of economic, demographic,political. cultural, technological, social changes) between two different types ofgeographical areas, i.e. urban and rural. These two points of concern lay afoundation for a further development of recent~v urbanization studies, called rural urbanization. So far. it is indicated there are three main streams of perspectives in urbanization studies, i.e. modernization, dependence, and inter-dependence urbanization. Each of these perspectives gives a special color on rural urbanization process. At least there are three fimdamental questions that can be raised from theoretical discussion of urbanization, i.e. (1) are distinct regions that recentlyemerge different from what conventionally known as rural and urban areas; and ifthese are special regions. (2) what are the underlying factors and forces that encourage the emergence of these distinct regions? (3). what kind of policies needed to effectively to cope the development of these distinct regions? These three questions actually are underlying three main areas of rural urbanization researchin a certain region, i.e.: (1) answering WHAT. WHERE, and HOW of the process of rural urbanization; (2) finding the main factors affecting the process; and (3) what kind of actions can be carried out dealing with rural urbanization 'problems

This study assessed the effectiveness of the existing land conservation techniques in the peril-urban area of Kadoka metropolis with the aim of ascertaining if the existing conservation methods have helped to alleviate land degradation, andprovide sustainable land use. Random sampling method was used to collect datafrom field observation, measurement and semi-structured interview which are analyzed using descriptive statistics. The results revealed that there exist local conservation techniques along with the modern techniques, some are physical and others are biological methods, even though techniques such as agI'o forestry, which is known to be the best method of farming is present but is yet to take root in the area. Some of these conservation methods are not standardized neither are they implemented in a scientific manner to. ensure e.Df!Ctiveness and efficiency without causing further damage to the lalld, as a result, there may be no end to land degradation in Kaduna if the current approaches to conservation are not improved on. it is suggested that improved water management, improved farming techniques, economic empml'ennent and education of the land users be employed in refilling existing techniques, through which poor management practices such as bush burning, monocropping and overgrazing lvill be avoided 'while fanners will easily embraced new practices such as agro forestry, which provides fanners with income and food all year round as well as protect the environmentfrom degradation.

McCall, Michael K.
Kingma, Nanette C.
Flooding has become a serious problem in Jakarta. During floods .of 2007, Kampung Melayu, East Jakarta was the worst hit.by the floods. Community have different perceptions on disaster and have different effort to overcome the hazards. Therefore, local government and relevant institution should investigate this situation and make this information a valuable input in developing and implementing response plans in flood mitigation. This research is to explore the vulnerability of floods based on local people's perception. There were 83 households interviewed using questionnaire. Certain elements at risk related with physical and socio:economic aspects were identified. Physical information concerned the building structure and building contents. Several socio-economic characteristics were used as key indicators to analyze the vulnerability of people. Generally, the result of this research shows that the ability of people to cope with the flooding i$ linked with the capacity of the people itself. The capability of people to deal withflooding was influenced by several indicators.based on their socio- . economic characteristics. For example, lower income people will experience more suffering than the wealthier, because they cannot afford the' costs of repair, reconstruction. Although the wealthier are likely to experience a higher degree of economic damage due to possessions of higher value. Base on the analysis, all coping strategies and flood measures are not enough to cope with flooding in the study area.

Canopy spectral measureme~t using ground-based hyperspectral r;leviceand rice crop variables such as leaf area index (LAI), leaf dry weight (LDW) andSPAD values were done periodically during growth season with involving threerice cultivars (Pandanwangi, Ciherang and IR Jumbo) ahd four nitrogenapplication levels (NO,N80, N92 and NI03 kg/ha). Thestudy is directed to exploreall possible waveband combinations tested in reflectance of vegetation indices(VIs) and to develop a predictive model of relation between hyperspectral-basedvegetation indiceswith rice crop variables. .Analysis of all possible two-pair waveband combinations used in VIs wasinvestigated with 6,786 combinations to gain optimal waveband attributed to cropvariables. To develop.efficient and accurate model, various multivariate regressionmodels were examined with ten-fold cross validations. Accuracy validation ofpredicted model was performed using reflectance and FDR, NDVI, RVI, RDVI andSA VI data. Validation of predictive model using flJR implied better accuracy toestimate LAI using whole season data (R2=0.856). Meanwhile, the model usingSA VI denoted highest values (R2=0.852)for predicting LAI While the validation ofpredictive model using RVI implied the highest values (K=O. 797) for predictingLDW. Moreover, the test of predictive model using SAVI indicated the highestvalue (R2=0.658) for predicting SPAD values. According to overall validationusing VIs, it seems that RVI has the best accuracy to validate the predictive modelof LAI than those of LDW or SPAD values. Meanwhile, the most significant of K tovalidate the predictive model was obtained on FDR data with R2=0.859for LAl

This work aims to estimate Above Ground biomass (AGB) of a tropicalrainforest in East Kalimantan, Indonesia using equation derived from the standvolume prediction and to study the spatial distribution of AGB over aforest area.The potential of remote sensing and field measurement data to predict standvolume and AGB were studied Landsat ElM data were atmospherically correctedusing Dark Object Subtraction (DOS) technique, and topographic corrections wereconducted using C-correction method Stand volume was estimated using field dataand remote sensing data using Levenberg-Marquardt neural networks. Standvolume data was converted into the above ground biomass using available volume- AGB equations. Spatial distribution of the AGB and the error estimate were theninterpolated using kriging. Validated with observation data, the stand volumeestimate showed integration of field measurement and remote sensing data hasbetter prediction than the solitary uses of those data. The AGB estimate showedgood correlations with stand volume, number of stems, and basal area.

Purnama, Setyawan
The objectives of the study are to map the distribution of rainfall in Java, toanalyze its potential and the impact to groundwater storage. To achieve thosegoals, rainfall distribution is mapped using isohyet method. From the averagedistribution of monthly rainfall, the annual potential of rainwater on everywatershed was calculated. Afterwards, the groundwater storage was analyzed andcounted by applying the water balance concept. The results of the study show thatthe mean of the highest annual rainfall is 4082 mm which occurs on Cisadane-Ciliwung watershed and the lowest one is 1421 mm on Citarum Hilir watershed.From the rainfall potential, Cisadeg-Cikuningan watershed has the highest rainfallpotential at the amount of 25342 million m31month and Grindulu Panggulwatershed has the lowest potential at the amount of 3678 million m3lmonth.Meteorologically, Cisadeg-Cikuningan watershed has the highest groundwaterstorage at the amount of 6088 million m31yearand the lowest amount of it occurson Madura watershed at 78 million m3lyear.

THE ENVIRONMENTAL IMPACT OF NATURE BASED TOURISM IN GUNUNG MERAPI NATIONAL PARK
Fandeli, Chafid
The goal of this research is to find out some impacts of tourism activities tothe environmental mainly to the biotic and non-biotic components. The researchalso focuses in finding out importance and performance of the products offered-byGunung Merapi National Park to the tourists. This research is done in fourlocations, consisted of the undisturbed location for controlling (Plawangan) andthe disturbed locations caused by the tourists, which are Kalikuning, Tlogonirmoloand Tlogomuncar. The result shows that the impClcts of tourist activities in somelocations show that the number of .microbial in the controlling location-is thehighest (54.56 cfu/gram) compared with others location. The impact to the numberof actin0mycetes in the controlling location is 32.84 cfu/gram, which is the highest.The infiltration rate with the model Horton in the controlling location is higher(0.983 cm/min) than the infiltration rates of the others. The voice frequencydescribes crowd level that at the controlling location has the lowest voicefrequency (10.15 dB). Some kinds of tree destruction as the impact of touristactivities show that the destructions happen mostly in Tlogomuncar, followed withKalikuning and Tlogonirmo 10. The most severe destruction of all locations isvandalism, and then scratch, spike prickling, branch breaking, and waste burning.Ihe importance and .performance of the products of the tourism objects offereddescribe that the attractions and tourism facilities like waterfall, musholla, shelter,dustbin, and observer tower have a considerable perception and goodperformance. However, some other facilities/attractions such as operational office,security center, gate, health clinique and bridge are not very important and not ina good condition.
