Mapping of carbon absorption based on land use in upstream of Jeneberang watershed

Abstract

Abstract This study aims to map land cover based on satellite imagery and identify carbon absorption in various land-use patterns. Data is collected by the observation method in the field and direct measurement based on the diameter of the tree to get the value of biomass. Biomass calculations are done using allometric equations, while carbon absorption values are calculated using IPCC GL 2006 software. The results of the study show that the upstream area of the Jeneberang watershed based on Alos imagery is dominated by dry land agriculture 48.94%, paddy 17.79%, shrubs 13.77%, and secondary forests 8.94% of the total area. Primary forest, secondary forest, and plantation forest are the biggest carbon storage areas in the upstream area of the Jeneberang watershed. Based on the IPCC GL 2006 software, primary forests, secondary forests, and plantations have carbon sinks of 42.08, 14.42, and 5.23 tons/ha/year, respectively.
