Adapting the global food system to new climate realities: Guiding principles and priorities

The effects of climate change are increasingly felt among vulnerable populations in many developing countries, particularly those relying on agriculture for their livelihoods, but also the urban poor. Adverse impacts include lower crop yields and crop nutritional values and ripple effects will be felt throughout the entire food value chain unless significant adaptation actions are taken. This paper takes a broad food system perspective and connects the roles and actions of international organi­zations, national governments, local communities and farmers. After an extensive review of the likely effects of climate change and the available adaptation responses, the paper identifies a series of guiding principles to be considered by decision makers as they plan adaptation actions.Non-PRIFPRI2; GCAN; CRP7; UNFSSEPTDCGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS
