Food and Nutrition Security and Climate Change: Strategies for a Sustainable Future

Author: ,       Publication Year:

There is growing acceptance that climate is changing, and will impact ecosystems and food production all over the world; in most cases, irreversibly. Food is an ecosystem service, which is mainly sourced from land and water ecosystems. While its availability and production depends on the health of an ecosystem, access to food depends on sufficiency of production as well as effectiveness of market and non-market distribution systems. Clearly, any change in these, especially decreasing production induced by climate variations or change would lead to food and nutritional insecurity. People living in resource-fragile areas such as arid and semi-arid regions (drylands) in developing and emerging countries, who earn their food and livelihood from the surrounding ecosystem, as also people living in low-lying plains, coasts, deltas, and islands would be particularly vulnerable.
