3. Results and Discussion
The land cover maps of Pasir Mayang area in 1993, 1995 and 1999 were indicated in Fig. 3. Estimation of above ground carbon stock was calculated by multiplying the unit value by total area of each land cover using the land cover maps of Pasir Mayang area. The same method was applied for calculating the total emission of GHG. These results are shown as table 1, 2 and 3. Forest was the most dominant land-cover in Pasir Mayang, followed by rubber/secondary vegetation, bush/shrubs, grassland and bare land (clear cut area) (Fig. 4).
Between 1993-1995, forest area decreased of about 5,000ha, while rubber/secondary and bush/shrubs land increased. Due to this, above ground carbon stock of the area decreased from 10.2 million ton to 9.6 million ton, or have loss of about 0.7 million ton. Between 1995-1999, forest area decreased of about 12,000ha, and also rubber/secondary and bush/shrubs land increased. Due to this, above ground carbon stock of the area decreased from 9.6 million ton to 7.8 million ton, or have loss of about 1.8 million ton.
