Spatio-Temporal Land Use and Cover Change Analysis in Southearn Region of West Java's Watersheds

Abstract

The regional development in south region of West Java is very slow, unlike in the northern region. There are two watersheds located in southern region, namely Cimandiri and Cibuni watershed which represent the condition in the southern region. Learning from the north region development, Cimandiri and CibUnI:f watersheds should consider the environment aspect in their land development process which can be achieved by studying the land use and cover spatially and periodically in both watersheds. The purposes of this study are to identify the land use and cover change in both watersheds periodically and to analyze the driving forces. The used methods are supervised classification and Logistic Regression Analysis (LRA). The results is land use map of Cimandiri and Cibuni watershed in 1978, 1995/6, and 2012, with their land use change maps and diagrams. Farm field, forest, and bushes field are dominating in both watersheds. Both watersheds are still undeveloped, since the built up area percentage is less than 5 percent. The driving factors for Cimandiri watershed are precipitation, population density, and distance to the city, and elevation, while those in Cibuni watershed are slope, population density, and elevation.
