FAO published its first global livestock distribution maps in 2007: the Gridded Livestock of the World (GLW). GLW is now in its fourth version and is a peer-reviewed spatial dataset on the global distribution and abundance of livestock species. These data find applications in the fields of food and nutrition security; livelihoods and economic growth; human and animal health and welfare; and natural resources and environment. The fourth version of the GLW has a reference year of 2015 and includes global distributions of cattle, buffaloes, sheep, goats, horses, pigs, chickens and ducks at a spatial resolution of 5 minutes of arc, approximately 10 km at the equator.
