Changes in land use and soil quality, carbon stocks and greenhouse gas emissions

Interactions between land use and soil and land quality is a focal point of several research projects in the group. Land use-soil quality interactions are essential for determining impacts of land use and land cover changes on productivity of agricultural land, as well as environmental impacts, specifically related to greenhouse gas emissions and carbon sequestration.

The main research focus is on highland areas in Southeast Asia, including shifting cultivation systems, oilpalm and other tropical plantation crops, conservation agriculture and general transformation to more intensified agriculture, but also includes work in temperate, intensive agricultural systems.

Our research takes point of departure in biophysical measures of soil quality, carbon stocks and greenhouse gas emissions from various production systems, linking them to farmer practices and decision criteria to analyse drivers of land use change. Focus is both on upland (tropical plantation crops) and lowland (rice) production systems in SE Asia, as well as on temperate, intensive agricultural systems.
