Spatial Production Allocation Model (SPAM) for 2010

Harvested Area - Maize Hectare per pixel
What We Do

This project provides global area, production and yield maps for 40+ major crops at 5 by 5 minutes resolution.

How Satellites Make This Work

Using a variety of inputs, IFPRI's Spatial Production Allocation Model (SPAM) uses a cross-entropy approach to make plausible estimates of crop distribution within disaggregated units. Moving the data from coarser units such as countries and sub-national provinces, to finer units such as grid cells, reveals spatial patterns of crop performance, creating a global grid-scape at the confluence between geography and agricultural production systems. Improving spatial understanding of crop production systems allows policymakers and donors to better target agricultural and rural development policies and investments, increasing food security and growth with minimal environmental impacts.
