FAO initiative brings global land cover data under one roof for the first time

A press release from FAO: A new FAO database released today collects previously scattered and unharmonized land cover information from around the globe into one centralized database, marking a major improvement in information regarding the physical characteristics of the Earth's surface.

Up to now, one of the major challenges to getting a good global overview of land cover - e.g. how much land is covered by croplands, trees or forests, bare soils, etc. - has been the fact that different countries and organizations go about identifying, measuring and recording such data in diverse ways.

But for FAO's new Global Land Cover SHARE database (GLC-SHARE), data pulled from multiple sources and partners was quality-controlled and harmonized using internationally accepted definitions and standards, bringing a wealth of country-level information into one consolidated dataset spanning the entire planet.

Applications of the new GLC-share database include monitoring of global land cover trends, evaluating the suitability of land for various uses, assessing the impact of climate change on food production, and land-use planning. "A strong understanding of our planet's land cover is essential to promoting sustainable land resources management - including agricultural production to feed a growing population - that makes efficient use of increasingly scarce natural resources yet safeguards the environment," said John Latham, of FAO's Land and Water Division....
