Conversion of forests to different land uses
Using satellite images, land use changes were determined at Batang Toru (2001-2009) and Tripa (2001-2009) to calculate overall CO2 emissions. Deforestation in both areas led to different land use transitions, with the pr...

Distribution of benefits under different land use scenarios in the Leuser Ecosystem
Net present value (NPV) is in millions of USD over a 30-year period (2000-2030) at a 4% discount rate. The NPV for local communities under a deforestation scenario would be 3,132 million USD and under a conservation scen...

Above-ground carbon-stock density changes
In Batang Toru, land use changes and deforestation led to an overall loss of around 10 tonnes of carbon per hectare between 1994 and 2009. Due to its exploitation for the cultivation of oil palm, the peat area of Tripa h...
