This report reviews current knowledge of the effects of climate change on hunger and provides an overview of actions that can be taken to address the challenge.
The report argues that unless climate change is mitigated by substantial greenhouse gas reductions it will greatly increase hunger, especially in the poorest parts of the world. In this context, the paper expects that the impact of climate change on hunger will be more profound where social inequality in development is maintained (e.g. Africa is expected to be the most affected region).
The document underlines that child malnutrition will be affected by climate change as a result of impacts on food production, prices and consumption. Consequently, the paper concludes that adaptation must be mainstreamed in the national strategies of developing countries. Further conclusions include following.

The need to adapt to climate change will be a fundamental driver of developments in agriculture and food security, which must be seen in the context of a range of risks facing poor people and developing countries.
Adaptation of farming practices could halve the increase in hunger related to climate change and reform of institutions could reduce the impact even further.
Agriculture should adapt not only to the direct impacts of climate change, but also to the impacts that emission reductions will have on the energy systems on which it depends.
Social protection policies relevant to food insecurity and climate change must include cash and in-kind transfers, employment guarantee schemes, mother and child health and nutrition, and weather-indexed crop insurance.
