The Food and Agriculture Organization of the United Nations (FAO) and the International Institute for Applied Systems Analysis (IIASA) have been continuously developing the Agro-Ecological Zones (AEZ) methodology over the past 30 years for assessing agricultural resources and perspective studies.  The GAEZ modelling framework for crop potential assessment uses detailed agronomic-based knowledge to assess land suitability, potential attainable yields and potential production of crops for specified management assumptions and input levels, both for rain-fed and irrigated conditions. GAEZ database outputs include thousands of global datasets. The tabular outputs are aggregated for current major land use/cover patterns and by administrative units, and land protection status. These outputs provide key data, knowledge and information related to availability of natural resources used in a number of applications including land evaluation, agricultural production potentials, sustainable management of natural resources, ecosystem services and ecologic and economic modeling. The GAEZ data portal aims at making available to the public the GAEZ database
