Climate Change: USDA's Ongoing Efforts Can Be Enhanced with Better Metrics and More Relevant Information for Farmers, Report to Ranking Member, Committee on Energy and Commerce, House of Representatives [open pdf - 3MB]
"In 2012, the United States produced about $395 billion in agricultural commodities, with about half of this revenue from crop sales and half from livestock. According to the Third National Climate Assessment, climate change has the potential to negatively affect agricultural productivity in the United States through warmer temperatures and an increase in weather extremes. In recent years, USDA has taken actions to help U.S. farmers adapt to climate change and reduce greenhouse gas emissions. GAO [U.S. Government Accountability Office] was asked to review USDA's climate change efforts. This review examines (1) USDA's climate change priorities and how these align with national priorities, (2) the status of USDA's climate change efforts, and (3) the challenges USDA faces in implementing its climate efforts and the steps it has taken to overcome these challenges. To conduct this work, GAO analyzed USDA documents and data and interviewed USDA officials and other knowledgeable stakeholders, such as farmers and environmental groups."
