GAEZ - Global Agro-Ecological Zones

About GAEZ Data portal Partners

GAEZ database and GAEZ data portal v3.0 is prepared and maintained by the Food and Agriculture Organization (FAO) of the United Nations (UN) coordinated by Land and Water Division (NRL) of the Natural Resources and Environment Department (NR) and International Institute for Applied Systems Analysis (IIASA).

About the Land and Water Division (NRL)

The Land and Water Division (NRL) aims at enhancing the agricultural productivity and advancing the sustainable use of land and water resources through their improved tenure, management, development and conservation. It addresses the challenges member countries face in ensuring productive and efficient use of land and water resources in order to meet present and future demands for agricultural products, while ensuring the long-term sustainability of the land and water quantity and quality. It promotes equitable access to these natural resources with a view to enhancing productivity, livelihoods and ecosystem services. It provides assistance to member nations in developing policies, programmes, best practices and tools in the fields of irrigation and drainage, soil conservation, drought mitigation, water rights, access to natural resources, and improvement of land markets.
Integrated land and water management is promoted through the development and improvement of irrigated and rainfed agriculture and through a river basin management approach, paying particular attention to enhancing the quality of the land and water resources and to reducing the impact of extreme climate events.


Founded in 1972, the International Institute for Applied Systems Analysis (IIASA) is an international research organization that conducts policy-oriented research. It has contributed to finding solutions to global problems by conducting independent and interdisciplinary systems analysis across a wide spectrum of environmental, social, technological and economic issues.

  • problems like climate change that have a global reach and can be resolved only by international cooperative action, or
  • problems of common concern to many countries that need to be addressed at the national level, such as energy security, population aging, and sustainable development.
