Climate change likely to raise wheat prices in food-insecure regions and exacerbate economic inequality

Wheat is a key source of nutrition for people across the globe, providing 20% of calories and protein for 3.4 billion people worldwide. Even if we meet climate mitigation targets and stay under 2°C of warming, climate change is projected to significantly alter the yield and price of wheat in the coming years. Researchers predict that wheat yield is likely to increase at high latitudes and decrease in low latitudes, meaning that prices for the grain are likely to change unevenly and increase in much of the Global South, enhancing existing inequalities.Wheat is a key source of nutrition for people across the globe, providing 20% of calories and protein for 3.4 billion people worldwide.
