To reduce greenhouse-gas emissions from agriculturally used peatlands a new agri-environmental measure for peatland protection through water logging was established. To investigate which factors influence the willingness of farmers to participate in the measure we apply a discrete choice experiment. Measure characteristics such as contract length, assured acceptance of the cut grass, support in the cooperation with neighbours, effort to register and financial compensation are considered. The very new scheme targeted at climate protection could therefore be adjusted and better tailored to different farm types.
