DYNAMICS OF LAND COVER CHANGE AND CARBON STOCK IN PAGARALAM CITY, SOUTH SUMATRA PROVINCEIfran D. Imanda, Sabaruddin Kadir, M. Umar Harun and Wijaya Mardiansyah
The City of Pagar Alam and its protected areas have experienced degradation and decreased carbon stocks due to periodic anthropogenic activities. However, the availability of information on this matter is still very limited. This research was conducted to assist in providing the intended information through a series of analyses of land cover change and carbon stock estimation using a remote sensing approach. The dynamics of land cover change have experienced an increasing trend or a decreasing trend in each period of the observation year. Meanwhile, the estimated carbon stock shows the highest carbon emission occurred in2000 - 2005 with emission values reaching 3,126,680.86 tons CO2-eq and the lowest carbon emission values reaching 759,508.44 tons CO2-eq occurred in 2010-2015. On the other hand, the highest sequestration value was the addition of carbon stock, which reached 2,026,747.63 tons of CO2-eq occurred in 2010-2015. The highest annual carbon emission rate in Pagar Alam city with a value of 6.54 tons CO2-eq/ha/year only occurred in the 2000-2005 period and the lowest emission rate occurred in the 2010-2015 period with a value of -3.97 tons CO2-eq/hectare/year. However, the emission rate for the 2015-2019 period is 1.52 tons CO2-eq/hectare/year. The triggers factor of land cover change that cause carbon emissions came from conversion activity of forest to shrubs. To assist and support the determination of climate change mitigation and adaptation strategies in a region, it is necessary to monitor periodically of land cover change and carbon stock in a certain area.
