Improving water quality is consistently ranked as a top environmental concern in OECD public opinion surveys. The key challenges for policy makers in addressing water quality issues in agriculture are to reduce water pollution while encourage benefits, such as maintaining aquatic life. This book examines linking policies, farm management and water quality. It looks at recent trends and prospects for water pollution from agriculture and the implications of climate change. It assesses the costs and benefits of agriculture's impact on water systems, and presents a series of case studies. Finally the report provides a set of recommendations for countries for meeting the challenge of improving agricultural water quality.
