Climate Change and Hunger - Responding to the Challenge

Climate change is a defining challenge of our times. Its impact and implications will be global, far-reaching and largely irreversible. Climate change is already increasing the risk of exposure to hunger, malnutrition and food insecurity among the poorest and most vulnerable people. Natural disasters are becoming more frequent and intense, land and water are becoming more scarce and difficult to access, and increases in agricultural productivity are becoming more difficult to achieve.

The figures presented in this report reflect recent scientific evidence on the scale of the projected impacts of climate change. By 2050, the number of people at risk of hunger as a result of climate change is expected to increase by 10 to 20 percent more than would be expected without climate change; and the number of malnourished children is expected to increase by 24 million - 21 percent more than without climate change. Sub-Saharan Africa is likely to be the worst affected region.

There is growing consensus amongst the international humanitarian community that adaptation measures are urgently needed to help vulnerable people cope with the changing environments in which they are living. This requires adapting global and local food production methods through investments, technical capacity transfers and technological innovations, while also making existing agricultural production systems more resilient, sustainable and equitable.
