"Confronting the double burden of malnutrition generates health and environmental benefits"
by Lopez Barrera, Emiliano and Thomas Hertel

Current food consumption patterns will continue to intensify pressure on the use of natural resources. This coincides with the prevalence of poor nutrition, both at low and high levels of calorie consumption, giving rise to an unprecedented global health challenge. In order to better understand the interplay between these food security, environmental and health challenges, we utilize a fully integrated framework which allows for analysis of the dynamics of the malnutrition double burden and its health and environmental impacts in the long run. We find that excessive caloric intake will play a key role in driving rising BMI levels, particularly in emerging economies. As a consequence of reaching higher levels of BMI at younger ages, future cohorts will increase their exposure to the health risks, including coronary heart disease, stroke, site- specific cancers, and type 2 diabetes. This framework also offers insights into the health, food, and environmental security impacts of changing food demand behavior. A key finding is that reductions in food purchasing (i.e., mitigation of food waste and excessive intake) are more important than changes in dietary composition in increasing food affordability and reducing pressure on cropland expansion, whereas dietary composition is critical in driving GHG emissions from livestock.
