Climate change: Food supply hangs in the balance

Rocketing food prices and hundreds of millions more starving people will be part of humanity's grim future without concerted action on climate change and new investments in agriculture, experts reported this week. The current devastating drought in East Africa, where millions of people are on the brink of starvation, is a window on our future, suggests a new study looking at the impacts of climate change. "Twenty-five million more children will be malnourished in 2050 due to effects of climate change," such as decreased crop yields, crop failures and higher food prices, concluded the International Food Policy Research Institute (IFPRI) study. "Of all human economic activities, agriculture is by far the most vulnerable to climate change," warned the report's author, Gerald Nelson, an agricultural economist with IFPRI, a Washington-based group focused on global hunger and poverty issues. The report, "Quantifying the Costs of Agricultural Adaptation to Climate Change", may be the "most comprehensive assessment of the impact of climate change on agriculture to date", as IFPRI claims, but researchers concede that there is no current way to quantify all of the future repercussions of changing weather patterns on the food supply.
