Emission and co₂ sequestration from land use and land cover change according to spatial planning in banyuasin regency, province of south sumatra

The aim of this study was to determine the carbon balance, emission, and CO₂ sequestration due to land use and land cover change in Banyuasin Regency from 2004-2014. The methods applied in this study included determination of carbon balance using the matrix of land use change and land cover change, calculation of carbon for each carbon pool by allometric and destructive sampling method, calculation of organic C through the method of Walkley and Black, and method of stock difference for analyzing carbon stock change, CO₂ emission and sequestration. Result of this study showed that carbon balance in Banyuasin Regency from 2004-2014 was negative with carbon loss of 22.033.277 tons and average annual carbon loss of 2.203.327 ton. Moreover, CO₂ sequestration, emission, and net emission reached 29.298.966 tons, 118.044.141 tons, and 88.745.175 tons, respectively. Average net emission of CO2 from carbon pool of above-ground, necromass, litter, and below-ground was 7 tons ha-1 year-1, while CO₂ emission from organic C in soil was 0,61 ton ha-1 year-1. It is expected that changes in peat swamp forest, secondary mangrove forest, primary mangrove forest, and secondary peat swamp forest majorly contributed to CO₂ emission in Banyuasin Regency.
