Sustainable farming meets environmental, economic, and social objectives simultaneously. Environmentally sound agriculture is nature-based rather than factory-based. Economic sustainability depends on profitable enterprises, sound financial planning, proactive marketing, and risk management. Social sustainability results from making decisions with the farm family’s and the larger community’s quality of life as a value and a goal. This 16-page publication discusses the principles of environmental, economic, and social sustainability, and provides practical examples of how to apply them on the farm.
