Micro spatial planning approach for effective peat restoration concept in Kahayan-Sebangau Rivers Peat Hydrological Units

Abstract

Abstract Peatland ecosystems play a pivotal role in supporting a diverse array of organisms and offer multiple benefits, encompassing functions as habitats, food sources, regulators of water systems, contributors to biodiversity, and carbon storage. Nevertheless, the degradation of peat can yield substantial consequences, including forest fires and floods. Although government regulations predominantly emphasize peat management on a larger scale, there is a noticeable absence of guidance for planning at meso and micro levels. The objective of this research is to bridge this gap by introducing a micro-scale planning approach for peat restoration. The methodology involves employing spatial analysis to create a micro Peat Hydrological Unit model. Official spatial data from various sources is meticulously processed using Geographic Information System (GIS) and categorized based on multiple factors, including elevation, depth, land cover, ecosystem function, hydrological network, and land management authority. The findings reveal the existence of 44 KHG micro-units, encompassing a total of 523 characteristics and covering an area of 451,081.54 hectares. Furthermore, the study identifies areas with varying levels of damage, with 938.33 hectares experiencing heavy damage, 95,657.21 hectares reflecting moderate damage, and 91,901.94 hectares showing light damage. Drawing on extensive experience in peatland management, the research presents strategic approach to enhance the effectiveness of peat restoration efforts.
