Deforestation, conversion of forest into non forest land use/land cover, especially in tropical forest area has been an international concern. Since forest hold the most carbon in terrestrial ecosystem, such changes give significant impact on the net increase of atmospheric carbon. In addition, land-use and land cover results in changes in greenhouse gases dynamics.
Spatial digital database of Jambi Province, Indonesia from various sources such as map, remotely sensed imagery, field measurement and statistical data were developed using Geographical Information System (Arc/Info) and remotely sensed analysis software (Erdas Imagine). Methodology to combine raster based and vector based data were explored. The database result then were applied to make assessment of historical land-use/land cover changes and its impact on above ground carbon stock and flux of soil carbon dioxide, nitrous oxide and methane.
Comparison result two periods of land-use/land cover data in 1986 and 1992 have showed that the loss of above ground carbon due the land-cover change in the study area (Jambi Province, Indonesia) was 8.3 millions ton annually or equal to 170.4 ton per sq. km. In addition, the loss of above ground carbon stock have influenced green house gases emission of soil surface.
