Sustainable agriculture is the production of food, fibre, plant or animal products using farming techniques that protect the environment, public health, human and animal welfare.
Sustainable agriculture incorporates many environmentally safe agricultural practices and offers innovative and economically viable opportunities for farmers, laborers, consumers, policymakers and many others in the entire food system. Sustainable farming systems are those that are least toxic and least energy intensive and yet maintain productivity and profitability. E.g. Organic farming.
