The 2030 Agenda for Sustainable Development puts a strong emphasis on the integrated approach to achieving Sustainable Development Goals (SDGs) that can harness synergies and minimize potential trade-offs, with land and water playing an important part in accelerating the achievement of many SDGs. As the world population is expected to reach 9.8 billion people in 2050, more efforts and innovations are needed to sustainably increase agricultural production, improve the global supply chain, efficiently use irrigation water resources, adapt to climate change, decrease food losses and waste, and ensure that all who are suffering from hunger and malnutrition have access to nutritious food.

The Agro-Ecological Zones (AEZ) methodological approach assesses land and water resources relevant for agricultural production. It was collaboratively developed by IIASA and the FAO over several decades and the AEZ framework principles and outputs contribute directly to a number of SDGs. Rapid developments in information technology have produced increasingly detailed and manifold global databases, which made the first global AEZ assessment possible in 2000. Since then, Global AEZ assessments have been performed every few years.

“The agricultural sector plays a pivotal role in the land-water-energy nexus, amplified by climate change and biodiversity loss. Agro-ecological zoning provides a variety of global data necessary for research and the planning of sustainable land and water use, agricultural production, and climate change adaptation,” explains Sylvia Tramberend, coauthor of the updated GAEZ platform and researcher with the IIASA Water Security Research Group of the Biodiversity and Natural Resources Program.
