A new United Nations’ report suggests just how climate change will reshape agriculture by 2050.
It says international trade will play an ever larger role in helping to feed people in food-deficit regions as warmer temperatures and less precipitation will damage yields in many tropical areas.
Temperate areas, such as Canada and the United States, are likely to see increases in agricultural production over that time.
That situation is likely to widen the food-supply gap between developed countries and developing nations, the report states.
The report called The State of Agricultural Commodity Markets by the UN’s Food and Agriculture Organization, said international trade will play a pivotal role in moving food from areas of surplus to regions where of shortages.
It says low-altitude areas of Asia, Africa and Latin America are likely to come out losers in terms of the impact of climate change on agricultural production.
It said yields by 2050 in West Africa could fall as much as 2.9 per cent and by as much as 2.6 per cent in India.
Canada could see agricultural production increase 2.5 percent by 2050 and Russian agricultural production could rise 0.9 percent, the report says. Canada could also see its net agricultural exports increase 21.9 percent, based on the FAO’s modelling.
The report also says that by 2050, agriculture on a global scale will have to find a way to increase production by 50 percent while also reducing greenhouse gases.
It suggested subsidies and policies that promote adoption of climate-friendly technologies and practices, as well as hedging tools to guard against extreme weather events.
