households and small industries and as poles for housing constitute another major cause of deforestation. Moreover, this induces selective cutting: most valuable species are cut first, which results in degraded forests and scrub. The need for fodder also contributes to largescale destruction of vegetation cover within forest areas. Forest degradation has reached proportions beyond the capacity and potential of the existing forests (Atmosoedarjo & Wahjoedi 1983). Reforestation efforts encounter numerous obstructions. The consequent deterioration of the environment has disturbed the water balance, resulting in floods, siltation of dams and canals, land erosion, losses of material and life, crop failures, and disturbance of fisheries activities. Forest management on Java requires a regional approach, involving the forest and its surrounding ecosystem. The study presented here is a tentative regional analysis of the importance and determinants of change in a typically degraded forest area (27,000 ha) of Central Java (cf. Fig. 1). A Geographic Information System (CIS) with a raster data structure (Burrough 1986) was designed in order to manipulate the large volume of data used for this study. 11.
