Land Use Change Assessment and Its Demand Projection in Batanghari River Basin, Sumatera, Indonesia

This study covers land use change in the region of Batanghari River Basin. Land use maps were derived from supervised classification of LANDSAT MS/ETM/OLI satellite imagery. The objectives of this study were to observe and analyse the changes of land use and project the temporal demand for each land use. Classification of images was categorized into six classes, namely water body, settlement, agriculture, bush, open land and forest. The validation for classification result using Kappa statistics with average accuracy of 85% -95%. Based on the classification results, the largest extent of land cover change is forest areas into agricultural areas. Changes in the area of certain types of land cover can be seen in the change detection matrix. This change was formulated for land use demands from recent past to near future, generating a dominant land use type of agriculture. The expansion of agriculture areas area about 22% (2015-2040), around 3.148.100 ha. On the contrary, forest areas decrease almost 50% (ha).
