Abstract

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.

Abstract

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.

Abstract

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

Abstract

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

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.
