Abstract
Improvements in the standard of quality and quantity of living necessities have led to competition for the use of agricultural and non-agricultural land. This has resulted in uncontrolled land use changes. Uncontrolled changes in land use can cause land degradation that threatens food security. Additionally, changes in land use put pressure on the environment. One effort to maintain the sustainability of these land resources is by studying the direction of land change developments that have occurred in the years prior. This study analyzes the spatio-temporal changes in land use in Gunungkidul Regency during the period from 2015 to 2023. Land use data was obtained from Sentinel 2 and Landsat satellite imagery and analyzed spatio-temporally using Geographic Information Systems (GIS). The findings indicate that significant changes occurred in the conversion of agricultural land into residential areas. The most substantial changes occurred in Wonosari Sub-district as the administrative center of Gunungkidul Regency, forming a pattern centered on service centers and spreading linearly along the access to these centers. Land changes also occurred in the northern and southern parts with a dispersed pattern. This research provides important information for better spatial planning and management in the future.
