Grid with estimated easily available soil moisture in mm/m with a spatial resolution of 5 * 5 arc minutes. Information with regard to easily available soil moisture was calculated from the "Derived Soil Properties" of the "Digital Soil Map of the World" which contains raster information on soil moisture in different classes.

Based on bovine density (FAO, 1999), livestock systems distribution, system-specific production parameters, calculations of output per animal to obtain milk production density (output per km2) were performed using the Livestock Development Planning System Version 2 model. Part of a study "Cattle and small ruminant production systems in sub-Saharan Africa: a systematic review" (FAO, 2002).

The raster map was originally produced from a multivariate regression predicting animal distribution from census livestock statistics and satellite-derived information (mainly environment and land development). More information about the original layer and its calculation can be provided from Jan Slingenbergh (AGAH) Jan.Slingenbergh@fao.org.The current map is an update of this previous one, based on more recent census data. The regression has not been updated.

Based on bovine density (FAO, 1999), livestock systems distribution, proportion of oxen in the cattle herd structures and system-specific information on the use of bovine draught power to estimate oxen-working days per km2. Part of a study "Cattle and small ruminant production systems in sub-Saharan Africa: a systematic review" (FAO, 2002).

Based on bovine and human population densities (FAO, 1999), livestock systems distribution, system-specific production parameters, calculations of output per animal to obtain milk offtake per capita were performed using the Livestock Development Planning System Version 2 model. Part of a study "Cattle and small ruminant production systems in sub-Saharan Africa: a systematic review" (FAO, 2002).

Based on bovine density (FAO, 1999), livestock systems distribution, system-specific production parameters, calculations of output per animal to obtain beef production density (output per km2) were performed using the Livestock Development Planning System Version 2 model.
