Agricultural Resources and Environmental Indicators, 2019, describes trends in economic, resource, and environmental indicators in the agriculture sector. Agriculture is dynamic, changing in response to economic, technological, environmental, and policy factors. The indicators covered in this report provide assessments of important changes in U.S. agriculture—the industry’s development, its environmental effects, and the implications for economic and environmental sustainability. The individual chapters track key natural, produced, and management resources that are used in or are affected by agricultural production, as well as structural changes in farm production and the economic conditions and policies that influence agricultural resource use and its environmental impacts. The chapters also direct interested readers to ERS research and data that provide more detailed description and analysis.
