Changes in global climate are already altering food systems and ecosystems worldwide. The chapter aims to identify the principal linkages between climate change and nutrition, and to elaborate mitigation and adaptation options for addressing the threat of climate change to nutrition security. The warmer average temperatures, increased rainfall volatility, and more frequent droughts associated with climate change have the potential to impact nutrition outcomes through three principal intermediate outcomes: (1) the quality and quantity of crop and livestock production, (2) the stability of ecosystems, and (3) the distribution and survival of disease vectors. These outcomes could adversely affect human nutrition via threats to food security, disruptions to and loss of livelihoods, increased vulnerability to infectious disease, and risk of regional conflicts. Efforts to mitigate and adapt to changing physical, economic, and social environments under climate change, particularly in low-income countries, will be critical to ensuring the progress of human development efforts.
