Landsat 8 OLI imagery based mapping of agricultural land change in 2014 to 2020 in Karawang Regency

Abstract

Land use change is a phenomenon that needs special attention, especially concerning the planning and development of a region. Agricultural land is the most vulnerable form of land use to change. Agricultural land was transformed or converted into other forms of land use for the industrial zone. Changes in agricultural land occur in various regions even in areas known for their rice productions, namely Karawang Regency. Information about changes or conversion of agricultural land, especially information with spatial references, is very important and needs to be kept up to date. This information is very useful as input in regional development planning. This study aims to map and analyze changes in agricultural lands in Karawang Regency. The study period was between 2014 and 2020. The method used was a combination of remote sensing image interpretation and spatial analysis. Interpretation of imagery was done using multispectral classification methods called maximum likelihood. The results showed that during the 2014-2020 period, agricultural land in Karawang Regency decreased by 27,659.57 hectares.
