The intersection of climate change, food security, and nutrition is critical given that the growing adverse impacts of climate change threaten food security and nutrition outcomes, especially for the most vulnerable in the global South. Climate is a potential driver of nutritional status, but dietary choices can affect both nutrition and climate. A better understanding of the pathways linking climate change and nutrition is key to developing effective interventions to ensure that the world’s population has access to sufficient, safe and nutritious food. Undernutrition can be exacerbated by the effects of climate change at all stages of the food value chain. In addition, disease is affected by climate and can, in turn, increase the demand
for nutrients, while reducing nutrient absorption.
