The Hertz-Chair Innovation for Planetary Health conducts population-based research into the interrelations of climate change and other planetary systems with dietary behaviour, nutritional status, and human health. The current research program focuses on identifying the impacts of climate change on diet and nutrition, characterizing features of sustainable diets, co-designing and testing approaches for climate change adaptation and resilience in the food system, and developing strategies for nutritional benefits of climate change mitigation. The work also comprises aetiological research into overnutrition-related chronic diseases and their interactions with undernutrition and infectious diseases. The regional focus is sub-Saharan Africa.
