Rapid Assessment of Spatial Variation of Carbon Sequestration in Coastal Landscapes of Bantul Regency, Indonesia: Implications for Land Management and Climate Mitigation

This study investigates the spatial variation of carbon sequestration across the coastal area of Bantul Regency - Yogyakarta, Indonesia, based on rapid assessment of carbon sequestration based on land use data. The land use classification is conducted by utilizing unsupervised classification Sentinel-2 classification data. Each land use is assingned carbon sequestration factor obtained from a number of literature studies. The analysis reveals distinct patterns of carbon sequestration linked to varying land use types and vegetation cover. The southern coastal zone exhibits lower carbon sequestration rates, primarily due to the presence of sand dunes, sparse vegetation, and urbanized areas. In contrast, the central region displays moderate to high carbon sequestration, driven by a mix of agricultural activities, such as rice cultivation and dryland farming, interspersed with natural vegetation and managed forests. The eastern region shows significant spatial variation, with pockets of very high carbon sequestration associated with dense forests and well-preserved natural areas. These findings underscore the importance of targeted land management strategies to enhance carbon sequestration, particularly in coastal areas, while optimizing sustainable land use practices in agricultural and forested regions. © 2025 Institute of Physics Publishing.
