Most low- and middle-income countries will require a substantial increase in greenhouse gas (GHG) emissions and water use due to their efforts to increase food production as these countries try to fight hunger, finds a new research from the Johns Hopkins Center for a Livable Future based at the Johns Hopkins Bloomberg School of Public Health.

Obesity, undernutrition, and climate change are major global challenges that impact the world’s population. While these problems may appear to be unrelated, they share food production and consumption as key underlying drivers. By recognizing the role of food production in climate change, this study examines the challenges of simultaneously addressing hunger and the climate crisis at both the individual and country levels.
