ROME (Thomson Reuters Foundation) - Asian farmers are growing rice and rearing fish in the same fields to increase their income and reduce weeds, while Ghanaians are using crop residues as compost to boost yields.

Such eco-farming techniques could deliver nutritious, environmentally friendly food for a growing world, increase farmers’ earnings and make farms more resilient to climate change, according to campaigners.

“Agriculture is in transition,” Pasquale Steduto, regional program leader for the United Nations Food and Agriculture Organization (FAO) in the Middle East and North Africa told the Thomson Reuters Foundation.

“Climate change is adding new uncertainty as well as increasing uncertainty. By introducing agroecology principles, you can reduce the risks of exposure to climate change.”
