The Food and Agriculture Organization (FAO) launched a database that centralizes previously scattered and un-harmonized information about land cover from around the world. Until now, FAO said different countries and organizations identified, measured and recorded such data in diverse ways.
The new Global Land Cover SHARE (GLC-SHARE) database uses data from multiple sources that has been quality-controlled and harmonized using internationally accepted definitions and standards. The database will be a "valuable tool in assessing the sustainability of agriculture, and for supporting evidence-based sustainable rural development and land use policy," he said.
The FAO says the new database has 11 layers: artificial surfaces (0.6% of the Earth's surface); bare soils (15.2%); croplands (12.6%); grasslands (13.0%); herbaceous vegetation (1.3%); inland water bodies (2.6%); mangroves (0.1%); shrub-covered areas (9.5%); snow and glaciers (9.7%); sparse vegetation (7.7%); tree-covered areas (27.7%).
