Not your usual SPAM but the Spatial Production Allocation Model
Authors: Ulrike Wood-Sichra
Downscaled production statistics from administrative units to pixel size resolution provide one of the layers to use when striving for food security and sustainable food production. Using a number of data layers from different sources and at different resolutions SPAM solves an optimization function to plausibly allocate area harvested for 42 crops, on a global scale, covering all crops deemed for human consumption and use. The results are presented in a 10x10 km grid.
