Discover AGROVOC multilingual Thesaurus of the Food and Agriculture Organization of the UN (FAO)... in Numbers!


1980: AGROVOC multilingual thesaurus was started by FAO, in order to provide access to semantic information (concepts, terms, and relations) covering all of FAO's areas of interest including food, nutrition, agriculture, fisheries, forestry, environment and other related topics.  

To date, AGROVOC is a collaborative international effort, coordinated by FAO, with up to 30 editors from all over the world contributing (active in the area of agriculture and related sectors) to the expansion of the...


  • 36,105 concepts, as at February 2019 (up from 34,576 one year ago)
  • 687,227 terms, as at February 2019  (up from 660,348 one year ago)
  • 33 languages


Since 2010, AGROVOC has been expressed as a Semantic Web concept scheme using Simple Knowledge Organization System (SKOS)

For the past decade, the technical e-infrastructure for AGROVOC has been managed in collaboration with FAO  by the Artificial Intelligence Research group, in Tor Vergata University (Rome). AGROVOC content editing is now in VocBench3 (VB3) - an advanced collaboration web environment for maintaining thesauri, ontologies, code lists and authority resources, providing features such as history, validation, a publication workflow, and multi-user management with role-based access control. 

VB3 supports the multischeme hierarchy approach, i.e. the use of hierarchical relation properties specific to a scheme. VB3 allows that AGROVOC hierarchy is viewed flexibly and edited with its customized relations, or exported with a generic SKOS hierarchy of broader and narrower relations, without changing the hierarchy of AGROVOC itself.
