The charity has identified how climate change may impact eight key crops produced for the food industry. “This issue is especially troubling in countries with less food diversity and where people rely on one or two staple foods for their nutrition,” she warned. Higher temperatures and increased concentrations of CO2 in the air will lead to lower levels of nutrients like iron, zinc and protein in crops like soy, wheat and rice.
The climate crisis is also expected to increase malnutrition by reducing nutrient availability and the quality of food, while increasing prices at the same time. Food storage may also become more challenging as rising temperatures make it more likely that insects or mould will destroy crops that are stored outdoors or in protected, but not cooled areas. As the climate warms and changes, pests and diseases are spreading more widely – adding another layer of unpredictability to farming. “It’s not just weather that will impact crop yields,” continued Escribano. For example, a 2019 study found that yields of crops like rice and wheat are already on the decline, while harvests of sorghum, which is more drought-resistant, rose during the same period. While researchers warn that overall crop yields will decrease due to the warming climate, surprisingly changing rainfall patterns and severe weather may see some crop yields increase.
“Not all crops are equally at risk,” explained the charity’s assistant director of communications at Action Against Hunger, Judith Escribano.
