A new version is out of the FAO global livestock density datasets, which we have blogged about before. This is the third iteration (GLW3), and it has a reference year of 2010. There’s a paper to give you all the details.1
But there’s more to come:
Future versions of GLW will differentiate stocks according to production systems for ruminant (meat vs. dairy) and monogastric species (intensive vs. extensive, meat vs. egg production). Higher resolution models2 for individual countries where the census data can support such predictions will also be produced.
The datasets are also available for download from Harvard Dataverse.Footnotes:
