Climate Change: Food Supply Hangs in the Balance
Uxbridge, Canada – 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.

This means extremes like droughts or floods will happen more often or last longer, and extreme temperature shifts are more likely. The past is no longer a reliable guide for farmers because the fundamental conditions in the atmosphere have been altered – far more heat is being trapped in the atmosphere today because of carbon dioxide and other greenhouse gases than at any time since the dawn of agriculture.

The enormous glacier system of the Himalayas-Hindu Kush and high-elevation Tibetan Plateau are the main source of water for 1.3 billion people in Asia. Recent studies as reported by IPS revealed that these glaciers are shrinking faster than anywhere on the planet and could melt away by 2035, according to the International Commission on Snow and Ice in Kathmandu, Nepal. … A similar situation is now evident in South America, where massive glaciers that provide water for tens if not hundreds of millions of people are melting away.

“Agriculture is extremely vulnerable to climate change because farming is so weather-dependent. Small-scale farmers in developing countries will suffer the most,” noted report co-author Mark Rosegrant, director of IFPRI’s Environment and Production Technology Division.

IFPRI’s call for a seven-billion-dollar investment will not guarantee that all negative impacts can be overcome, acknowledged Nelson, “But business as usual will guarantee disastrous consequences for the human race.”
