Identification of the agricultural land conversion rate in Sleman regency using remote sensing

Abstract

Lack of information concerning the conversion rate of agricultural to non-agricultural land in the last decade has become an important issue in Sleman Regency. The aim of this study was to determine the changes in land use and the land conversion rates in five years for three periods of 1990-1995, 2000-2005, and 2010-2015. The study was conducted using descriptive methods which were analyzed spatially using Landsat imagery of 1990, 1995, 2000, 2005, 2010, and 2015. Identification of the land conversion rate covered 17 districts by comparing the land use classification data. The results showed that land use in Sleman Regency cover paddy fields, moorlands, yards, forests, barren land, and other land uses. The highest rate of land conversion occurs in groundwater bodies, paddy fields, and plantation area in different periods. The highest rate of land conversion in Sleman Regency in period 1 (1990-1995) was in paddy fields, which was 8,953.04 ha or 1,790.61 ha/year. In period 2 (2000-2005), the highest land conversion rate was in groundwater bodies, which was 3,471.44 ha or 694.29 ha/year. Meanwhile, in period 3 (2010-2015), the highest land conversion rate was in plantation areas, which was 7,767.33 ha or 1,553.47 ha/year.

Assessment of Land Use Change Impacts on Land Capability in Ngadirojo, Indonesia

“…Landowners convert their land to expect more profits (Sianipar, 2016). Aini et al (2019) stated that three factors influence the conversion of agricultural land, which is more common in paddy fields. First, the development of housing, shops, offices, and industrial areas is easier to do on flatter paddy fields.…”

“…Population growth and increasing economic development have led to an increase in land demand. The availability of land that is fixed but needed for all sectors causes land conversion, especially on agricultural land (Aini et al 2019;Widhiyastuti et al 2023). Developmental factors, either economic or demographic, have an impact on the conversion of agricultural land (Egidi et al 2020;Kumar and Agrawal 2019;Kocur-bera and Pszenny 2020).…”

Urban Development Project Evaluation Using Multi-Stakeholder Cost–Benefit Analysis

“…Second, urbanization and its concomitant physical development were followed by intense socio-environmental conflicts. In Sleman, physical development is associated with the problematic rapid conversion of natural land (Aini, Dewi et al, 2019). As released by the local government, the conversion of agricultural land in Sleman has reached more than 100 ha per year.…”
