Agri-environmental Programs in the United States and Canada.

Canada and the United States have a rich history of policy interventions aimed at improving environmental outcomes from agricultural production. We review the agri-environmental programs in these two countries as well as the related economic literature. Despite the impacts of agriculture on land, water, and climate quality, the literature on agri-environmental programs has largely focused on a few major programs or the adoption of specific management practices. Far less research evaluates programs on active farmland, environmental regulation of agriculture, and the interactions of these policies and programs. Further research is also needed on how the heterogeneity of environmental characteristics and processes affects the outcomes of management practices and how these outcomes might be affected by climate change. Given the continued substantial impacts of agriculture on environmental outcomes, the increased interest of agricultural processors and consumers in these outcomes, and the potential for new models and data to inform research, we conclude that this is an ideal time to examine and apply lessons learned from past program successes and failures as we seek to improve the performance of the next generation of agri-environmental policy interventions.
