Global warming is likely to significantly diminish food production in many countries and greatly increase the number of hungry people, the U.N. Food and Agriculture Organization said Thursday. FAO said in a report that food distribution systems and their infrastructure would be disrupted and that the severest impact would likely be in sub-Saharan African countries.
Changes in temperature, rainfall as well as an increase in the number of so-called "extreme weather events" such as floods will bring with them potentially devastating effects. The world suffered 600 floods in the past two and a half years, which claimed the lives of about 19,000 people and caused $25 billion in damages, excluding December's devastating tsunami in southeast Asia that killed more than 180,000.
FAO said scientific studies showed that global warming would lead to an 11 percent decrease in rainfed land in developing countries and in turn a serious decline in cereal production. "Sixty-five developing countries, representing more than half of the developing world's total population in 1995, will lose about 280 million tons of potential cereal production as a result of climate change," FAO said.
The effect of climate change on agriculture could increase the number of people at risk of hunger, particularly in countries already saddled with low economic growth and high malnourishment levels. "In some 40 poor, developing countries, with a combined population of 2 billion ... production losses due to climate change may drastically increase the number of undernourished people, severely hindering progress in combating poverty and food insecurity," the report said.
