Estimasi Stok Karbon di Kawasan Penambangan Akibat Perubahan Luas Penutupan Lahan Terkait dengan REDD

Abstract

Deforestation and forest degradation caused by mining has had very great impact to global climate
change, because one of the functions of forest vegetation is very important is capture and storage
CO2 emissions. Revegetation activities in the area of mining is done in order to restore the forest
vegetation. Research to estimate absorbtion CO2 as a result of carbon stock by forest vegetation
needs to be done . Remote sensing technology through radar imagery can be applied to estimate
forest vegetation carbon stock more quickly and efficient. The research was conducted in the gold
mining area of PT . JResources Bolaang Mongondow. Main objective of this research is to estimate
changes in forest covered land due to mining activities, estimation amount of carbon stored in 2008 ,
2009, and 2010 and the economic value that can be obtained from stored carbon, using the
estimated price based REDD schemes. The methodologies for measurements of the variables used in
the calculation variable of above ground biomass using allometric and ALOS PALSAR image analysis
of 2008, 2009, and 2010 to estimate the carbon stock in forests. The results showed there were
widespread changes in forest land cover due to mining activities, and based on image analysis of
2008 , 2009, and 2010 , the amount of carbon stock in the research area respectively are
32,695,253.57 ton C, ton C 50,146,772.71 and 79,420,248.55 ton C. The economic value of carbon
stock in 2010 are Rp.7,538,299,190,029.09 with price estimates and assumptions based on REDD
scheme BAU Carbon savings in 2008.
