Project Description: There have been intense interests in carbon sequestration and greenhouse gas (GHG) emission reduction in the agricultural sectors recently. Meanwhile, there have been decades of efforts and investment to reduce nutrient loss from agriculture. From a policy standpoint, carbon and nutrient reduction are inseparable for to two reasons: (a) most conservation practices that reduce nutrient loss also sequester carbon; and (b) both government and private incentives can be used to support the same set of conservation practices. By investigating these links, our team of cross-disciplinary researchers and non-governmental organization (NGOs) partners will evaluate how carbon credit programs will affect nutrient loss reduction with a focus on farmers’ decision-making regarding program participation.
