FAO, in collaboration with the International Institute for Applied Systems Analysis (IIASA) and the Geomatics Unit of the Asian Institute of Technology (AIT) developeda free and open source tool to run Agro-Ecological Zoning (AEZ) at different levels. Powered by Mississippi State University's high-performing supercomputer,PyAEZ generates global layers on land productivity, crop suitability, and water demand, facilitating identification of constraints and yield gaps. FAO and MSU jointly hosted an event on 27 June 2023, showcasing advancements in land evaluation, crop mapping, and agro-ecological zoning for sustainable agriculture.
