Estimated value of crop and livestock production by agricultural domain (US$ million), 2003–2005. Source: authors. (Value of production is computed from the average annual production of FAO crop and livestock commodities/products for the period 2003–2005 and international prices for the period 1989/91—the most recent time for which a full set of compatible prices for all commodities was available. *Other includes extensive grazing lands that fall outside of the global extent of agriculture as defined using satellite and climate data as well as areas where satellite and climate data are not available (e.g. islands, some coastal areas). Afghanistan, Iraq and Somalia are not included due to lack of data for 2003–2005.)
