The FAO Glossary on Organic Agriculture in English, French and Spanish contains 401 concepts and definitions, where appropriate, which have been selected from FAO and international documents and publications on Organic Agriculture, as well as from the proceedings of meetings of experts discussing Organic Agriculture and Food Security issues. The concepts are accessible online through the Organic Agriculture Web site at http://www.fao.org/organicag/en/ with the objective of maintaining the collection through time, with additions and amendments to the concepts as they evolve in FAO's work.
