Abstract
The research objective was to study emission rate and carbon sequestration in extin minimg land, with Bangka Belitung Province as the case site. Emission projections are carried out until 2040 based on historical emissions from 2000-2013. The results showed that in the period 2000 - 2013 there was an expansion of the tin mining area in the province covering an area of 22,642 ha, causing a decrease of 19,507,142 t of soil C stock and 10,056,896 t of plant C stock and emissions (sourced from plants only) of 36,908,808 t CO2 eq. There are two scenarios we propose here to reduce emissions: Scenario 1, avoid the opening of primary forest, primary and secondary swamp forests, and reclaim 80% of the tin mined land area by planting perennial crops such as plantation/estate crops or industrial forest. Scenario 2, equals Scenario 1 plus a reduction in the rate of secondary forest clearing for various uses by 50%. Scenario 1 will potentially able to reduce emissions by 8% and carbon sequestration by 8,000,000 t CO2 eq. and scenario 2 reduced emissions by 26.97% with carbon sequestration 32,500,000 t CO2 eq.
