Post-harvest losses — which can range between 10-20% in major cereals — cause not only the loss of economic value of the food produced, but also the waste of scarce resources such as labor, land, and water, as well as non-renewable resources such as fertilizer and energy.
“High postharvest losses imply reduced grain yield, but with the same total greenhouse gas emission,” says Rabé Yahaya, a CIM/GIZ Integrated Expert working at the International Maize and Wheat Improvement Center (CIMMYT). “Reducing these losses reduces the yield-scaled global warming potential — total greenhouse gas emission per kilogram of grain — and contributes to climate change mitigation, as well as food security.”
