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.

Thousands of pests and diseases affect our major livestock species, with impacts on livestock production varying in space and time.

To improve our collective capacity to model and measure the economic costs of pests, weeds and diseases of the major food crops of the world, CSIRO and HarvestChoice-UMN are delivering a series of ecological modeling workshops.

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

Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and HarvestChoice are now working together to apply innovative, “bio-economic” approaches to improve the food security of poor people in sub-Saharan Africa and South Asia. Together, our organizations will merge biological, environmental and economic tools to track global food pests and better target strategic investments to improve global food security.

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.

Crop systems models can help researchers estimate the future of food security under climate scenarios. Many crop models are known to exist around the world - for different crops with varying complexities, yet it is not easy to find the right model for the right problem. To better understand the global extent of crop model development and to identify gaps in capabilities, HarvestChoice participated in an initiative to conduct a rapid meta-analysis of crop models using on-line survey to the crop modeling community in the world. Here are the key findings.
