ROME - "The poorest countries where food is scarcest will find it increasingly difficult to feed themselves as global warming exacerbates desertification and drought, a United Nations food agency expert said on Wednesday. With climate change and poverty at the top of the agenda of a Group of Eight summit which opens on Wednesday, the Food and Agriculture Organisation (FAO) said the two issues would be increasingly intertwined in the coming years.
"Climate change will have a tremendous impact on food security, especially in Africa and also in some parts of Asia and Latin America," said Wulf Killmann who chairs a working group on global warming at the Rome-based food agency.

The UN Intergovernmental Panel on Climate Change has predicted global temperatures could rise by up to 5.8 degrees Celsius this century. In the developing world, global warming is likely to reduce the amount of rain-fed land where crops could be grown by 11 percent by 2080, according to a study by the FAO and the International Institute of Applied Systems Analysis (IIASA).
Killmann stressed there were many uncertainties in the scenarios mapped out in the research, but the general conclusion was clear. "Those who are already suffering from hunger will be suffering even more." Sixty-five developing countries will lose about 280 million tons of potential cereal production, equivalent to about 16 percent of agricultural output."
