Livestock densities • • • • • •

Gridded Livestock of the World (GLW) Global coverage 5 km resolution GIS data All major livestock species Predicted densities, standardised to 2000 and 2005 (FAOSTAT) Freely available in graphic, GIS (ESRI) and Google Earth formats

Wint and Robinson (2007)

Livestock densities • • • • Modelled cattle density

AGAL

• • •

Collect sub-national statistics Geo-register (link to shape file) Convert to densities, adjusted for area ‘suitable’ for livestock Compile predictor variables and stratification layers Derive statistical models of livestock densities for each stratum Apply models to predictor variables Adjust density maps to match official, time-standardised FAOSTAT totals

Livestock production systems •

Ruminant systems: based on land use and agro-ecological potential

•

Monogastric systems: based on scale and intensification
