Sustainable agriculture refers to the ability of a farm to produce food indefinitely, respecting the health of the natural ecosystem and resources, supporting the rural community and offering respect and fair treatment to all involved, from farm workers to consumers to the animals raised for food.

Two key issues are biophysical (the long-term effects of various practices on soil properties and processes essential for crop productivity) and socio-economic (the long-term ability of farmers to obtain inputs and manage resources such as labor).
