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).
