Land use land cover change in Badung Regency, Bali

Abstract

Demand for land use can cause an undesirable impact. Bali Island has been exploited as the midpoint of tourism activities and altering land use over the last two decades. Badung regency is the hinterland area of Denpasar City, the capital city of Bali Province. Land conversion in Badung was caused by the construction infrastructures related to tourism development. Conversion occurred from agricultural lands to built-up lands. This research analyzed remote sensing data, taking the advantage of abundant, serial data acquisition. This study used Landsat 7 ETM and Sentinel 2 satellite images obtained from 2010 to 2020. Land cover types were identified by visual interpretation and LULC changes were analyzed by overlaying land use maps. Identified land-use types included eight categories, i.e. paddy fields, forests, mangroves, built-up areas, mixed gardens/plantations, upland fields, shrubs, and water bodies. Land use has changed significantly in the past 10 years especially in built-up areas, upland fields, and paddy fields. The trend showed that built-up areas persistently increased from 2010 to 2020. Paddy fields, shrubs, mixed gardens/plantations, and mangroves fluctuated in terms of the acreage; rose from 2010 to 2015, but were reduced in the rest of the period. Water bodies did not change throughout.
