Other, less direct linkages exist between climate change and human health. For example, regional climate change impacts on agricultural yields and production are likely to grow over time, with the most negative effects expected in developing countries. This is expected to increase the number of undernourished people globally and consequently lead to complications in child development (IPCC, 2007).

Climate change may also contribute to social disruption, economic decline, and displacement of populations in certain regions, due to effects on agricultural production, already-scarce water resources, and extreme weather events. These issues are likely to be more severe in developing countries, and may worsen human health and well-being in affected regions (IPCC, 2007).
