Until recently we at HarvestChoice had no idea that people live in NUTS. Within the European Union they have switched from administrative entities as the unit of statistical reporting for each country to sub-divisions, or what they call NUTS. What does this have to do with HarvestChoice? SPAM 2005, one of its flagship products, needs to know the statistical reporting unit in each country for accurate spatial allocation of crop production around the globe.

Characterizing global production systems just got easier. IFPRI/HarvestChoice has updated SPAM, from circa 2000 to centering on the year 2005. That’s right; SPAM 2005 is out for release and freely available to the public. That means more accurate and up-to-date spatially disaggregated crop production statistics and more of it.

Capturing the heterogeneity of VoP (Value of Production) across sub-Saharan Africa in a spatially explicit way is another example of what we do at HarvestChoice. Because informed decision making in agricultural development doesn't just rely on knowledge of important indicators, but a geographical context of where.

It may get stuck in your junk folder, confused with a tin of mysterious food, or buried in a Google search (try adding a few more key terms), but for now the name sticks (and sticks in your memory); SPAM (Spatial Production Allocation Model) is not getting a new name anytime soon. That’s just one of the items key players discussed at a recent SPAM workshop.

SPAM2000 (any version) is based on a large set of data which centers as much as possible on the year 2000: land cover / land use (Boston University’s MODIS-derived land cover 2000 and JRC’s GLC2000), crop suitability (Global AEZ Zones 2000 by FAO and IIASA), irrigated areas (FAO and CESR of University of Kassel), population density (CIESIN), and, most importantly, national and sub-national crops statistics for 2000.
