Impacts of climate change on the agricultural and aquatic systems and natural resources within the CGIAR’s mandate

The document attempts to distil what is currently known about the likely impacts of climate change on the commodities and natural resources that comprise the mandate of CGIAR and its 15 Centres. It was designed as one background document for a review carried out by the High Level Panel of Experts on Food Security and Nutrition (HLPE) at the behest of the UN Committee on World Food Security (CFS) on what is known about the likely effects of climate change on food security and nutrition, with a focus on the most affected and vulnerable regions and populations. A total of 25 summaries covering 22 agricultural commodities, agroforestry, forests and water resources, present information on the importance of each commodity for food and nutrition security globally, the biological vulnerability of the commodity or natural resource to climate change, and what is known about the likely socioeconomic vulnerability of populations dependent partially or wholly on the commodity or natural resource.
