2011 was the first year of operation of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). CCAFS brings together the work of all 15 international Centres in the CGIAR, and is a joint programme between the CGIAR and the Earth System Science Partnership (ESSP).

Addressing these challenges requires a combination of good science, integrated research-for-development approaches, and effective partnerships.
