Abstract
Carbon dioxide (CO 2 ) budget from tropical peat lands in Indonesia was estimated by using satellite data. Indonesia has many CO 2 sources that related with peat lands. Our previous results have been continued to estimate CO 2 budget from ground water decreasing. The new motivation of this study is to estimate human impact on the peat lands hydrologic environment. The drainage canal is supposed to be artificial in this region. ALOS PALSAR mosaic data was used for detection of drainage canal in Indonesia. Canny edge detection method was used. As the result, daily soil respirations of Jambi and Palangkaraya became 12.63% and 16.84% larger than before consideration of human effect.
