The impact of land use and land cover changes on ecosystem service value in Aceh Besar Regency, Aceh, Indonesia

Land use and land cover (LULC) have a signifi cant impact on changes in the value of ecosystem services. Therefore, this study investigated the relationship between ecosystem service value (ESV) and LULC in Aceh Besar Regency by calculating nine ESV variables, namely gas regulation (GR), water supply (WS), soil formation (SF), waste treatment (WT), biodiversity protection (BP), food production (FP), raw materials (RM), recreation (RC), and culture (CT) on each type of land cover in Aceh Besar Regency in three years: 2000, 2010 and 2020. The results showed that both decades saw in all three years, there was a decrease in the value of the forest ecosystem in Aceh Besar Regency due to the addition of activities and population needs, resulting in the conversion of forest land into built-up areas. This indicates that there is a relationship between land use and land cover change and human activities that have the potential to negatively affect the value of ecosystem services.
