Mapping of Agricultural Land Conversion in Temon Sub-district after the Development of Yogyakarta International Airport

Abstract

Yogyakarta International Airport (YIA) and supporting infrastructure in Kulon Progo Regency, Yogyakarta, aims to encourage economic growth and support the tourism, industrial, trade, and education sectors. This study aimed to monitor the pattern of changes in land use that occurred after the construction of the YIA, especially in the agricultural sector. The quantitative method with spatial analysis through overlay was chosen to produce multitemporal land use change maps (2018 and 2022). The preparation of the land use map was carried out through the visual interpretation of Pleiades satellite imagery with a spatial resolution of 0.5 m. The results of the study showed that there had been a very massive change in land use in the Temon Sub-district, especially in relation to the decrease in the area of agricultural land. The impact of the construction of the airport and its supporting infrastructure in the Temon Sub-district had resulted in a reduction of 21.24 hectares of rice fields. Land use from agricultural land had mostly changed to the construction of YIA, infrastructure development, and built-up land (settlements, hotels, restaurants, trade, and services). The increasingly massive decrease in the area of agricultural in the study area needs attention from the government so that the existence of agricultural land remains sustainable, considering that most people depend on the agricultural sector for their lives.
