An interactive website that delivers essential components to ensure adequate, sustainable food production and food security through satellite based maps was relaunched by the International Food Policy Research Institute (IFPRI) and the International Institute for Applied Systems Analysis (IIASA) recently.
Called Spatial Production Allocation Model (SPAM), the website includes maps that were produced using satellite images and then improvised by a global crop mapping community on ground. The community through the evaluation of remote sensing imagery ensured the accuracy and made changes accordingly.
The satellite maps direct locations of cultivations of 42 crops such as rice, cassava, potatoes, wheat and maize down to a resolution of about 10 km at the equator. With it showing where in the world individual crops are cultivated, their production patterns, and whether they are irrigated or rain fed. The maps can be overlaid with other geospatial datasets to help with other aspects of food security as well, such as crop productivity, climate change, ecosystem services and social welfare.
