The Dynamic of Spatial Extent of Land Use in the Fringe of Jakarta Metropolitan: A Semivariogram Analysis

Abstract

Spatial interaction of land use is one factor which drives land use change. A recent study indicates that in the fringe of Jakarta Metropolitan, the significance of land use externalities creates sprawl. This inefficient development activity leads to premature conversion of some environmentally sensitive sites in the southern fringe. A proper land use policy to protect those sites should be formulated based on precise information about the extent of land use externalities. The development of semivariogram analysis enables the formulation of this distance, which is the aim of this study. Applying the analysis for two years data, this study indicates that, in this area the furthest distance for interaction between developments is between 21-29 km, while the interaction between agricultural uses are still in effect between 29-30 km. Those results will be useful to predict the future land use change in the area.
