Sustainable Forest and Biodiversity Management in the Heart of Borneo (HoB) of Kalimantan (TA 8331-INO Project) : “Land Cover Change Analysis and Carbon Emission Assessment For district of Malinau and Kapuas Hulu”

17 Mei 2017 | EmailKirim Teman

Land cover changes analysis and carbon emission assessment is part of Plan Vivo requirement to provide deforestation and emission rate from the selected project area (customary forest of PunanAdiu in district of Malinau and village forest of Nanga Lauk in district of Kapuas Hulu).  The works in particular at district level were done as continuation from the previous activities completed by GIZ FORCLIME Project No. 2007.2135.7.  The time frame of this assessment is 2010 to 2016. Yet the analysis will be incorporated with the FORCLIME analysis which covered 2005 and 2010.

The methods are mainly using Spatial Quantitative Analysis based on remote sensing and GIS analysis on the land cover change in the target areas. The following are summary methodology of the works.

  • Land cover change analysis and carbon emission maps and reports of the area of interest (AOI);
  • Assessment of updated reference emission level (REL) data and reports of the AOI;
  • Defining baseline of assessment on 2005, 2010 and 2016
  • Data compilation from satellite imagery taken from Landsat and ESA data portal and historical data of land cover of AOI 2005-2010

The results indicate that there is deforestation in both districts over the observation periods. The deforestation and carbon stock in customary forest of PunanAdiu and village forest  are also presented in the following tables.

The deforestation and emission in customary forest of PunanAdiu was calculated by sub-setting the deforestation data of district of Malinau using similar procedure. The results are presented in Table 3 and 4.
