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.

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.

Picture it. You're working at HarvestChoice processing incoming crop statistics and you come across some figures for harvested area of dolichos in Kenya.

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.

Many of HarvestChoice spatial datasets are organized and released on 10-km grids. To make spatial analyses easier for researchers (even without having access to GIS platform), we put data layers from multiple themes together in one denormalized big table. This post describes the methodology and presents a prototype.
