Abstract

Land-use change in the Northern Part of Bandung Regency presents a significant risk of soil erosion and contributes to flooding in the city of Bandung. This purpose of this study is to identify the soil erosion risk associated with land-use change using geographic information systems by employing the revised universal soil loss equation (RUSLE) model in Cimenyan and Cilengkrang Districts.

The model requires datasets to be multiplication from various sources, such as Landsat images, Digital Elevation Model (DEM), rainfall data, soil data which are then utilized as factors contributing to erosion. Each of these factors has been represented on a thematic map. Landsat satellite images from 2013, 2018, and 2023 were used to assess the land-use change. From the image analysis indicates a significant increase in agricultural zones (from 7.95% to 22.65%) and uncultivated land (from 4.50 to 13.50%). The erosion rate categorized into five classes which are very low, low, moderate, high and very high. The erosion rate rises from very low to high levels, but it decreases when it reaches the very high level (from 73.68% to 30.72%) from year 2013 to 2023.
