Description
Summary:Serang is one regency in Banten Province which is located near to Jabodetabek, the largest metropolitan area in Indonesia. The economic growth at its periphery has a negative impact on the decreasing of rice field in the regency. Objectives of this research are: (1) to analyze decreasing of rice field in Serang Regency from 2006 to 2018 and to project land-use change in 2030, and (2) to identify spatial distribution pattern of rice field in Serang Regency. Land-use change was conducted by ArcGIS10.3 using Landsat images. Identification of spatial distribution pattern of rice field was conducted by Moran and LISA (Local Indicator of Spatial Autocorrelation). Meanwhile, land-use change projection was conducted using CA-Markov. Results show that during 2006-2018 there has been an increase of built-up area (7,295 hectares) and decreasing of rice field from 60,949 hectares to 54,232 hectares. A larger decreasing rice field occurred at districts located at the eastern part of Serang Regency. The result of land-use change projection shows the increase of built-up area and rice field conversion in Serang Regency in 2030. Decreasing rice field in the long term may threaten food security at the local and regional level.
