A study published in the ‘Journal of Environmental Economics and Management’ revealed that exposure to extreme heat increases both chronic and acute malnutrition among infants and young children in low-income countries. The study included more than 32,000 children from West Africa between the ages of 3–36 months. The study found that the average heat exposure increased the prevalence of stunted growth from chronic malnutrition by 12% and of low-weight from acute malnutrition by 29%.

The researchers from Cornell University estimated that if the average global temperature rose by 2 degrees Celsius, the average effect of heat exposure on stunted growth would nearly double. The effects of acute and chronic malnutrition in early childhood were also linked to high mortality rates, lower educational qualifications, and low income in adulthood. Dr. Sylvia Blom, PhD., stated that the strategies to reduce child nutrition should include rehabilitation programs during periods of prolonged heat exposure. On the other hand, improved incomes, infrastructure, and childcare practices during the study period helped in reducing the rate of stunting by 5.8% across the five West African countries.

Dr. John Hoddinott, a professor of Food and Nutrition Economics and Policy at Cornell University, stated that though the progress during the study period was a relief, it occurred against the backdrop of rising temperatures and an increased likelihood of extreme weather conditions.
