Climate change has multiple pathways to directly and indirectly impact human health. There is a strong connection between global warming and agricultural crops production through low precipitation, high temperatures, and drought. The lower crops production impacts quality and quantity of foods and their availability to low income communities. Our parent grant is leading the field of research in climate change and health through the Global Center for Climate Change and Water Energy Food and Health Systems (GC3WEFH) in rural Jordan. We are bringing together a large and diverse group of scientists to develop solutions and potential policies and interventions to help vulnerable populations cope with climate change health impacts. In this Administrative Supplement we will complement the existing focus of the parent grant on water quality and quantity with new data and focus on dietary quality and quantity. We established a robust team of scientists and community engagement of residents in the municipality of Alkhaldyia in Northern Jordan to address water access through an intervention of water desalination. This supplement will extend this effort to understand diet quality and food security within this same community and its relation to water and noncommunicable diseases in the context of climate change. We will recruit up to 100 homes from the target population and 1) measure nutrient adequacy, sources, and dietary quality of consumed food as risk factors for noncommunicable diseases; 2) determine if farming communities have adequate access to food and the level of food insecurity among these impoverished communities; and 3) include the collected dietary data into the WEFH modeling and tradeoff analysis that is being developed by the parent GC3WEFH project. We will expand our team to include expertise in clinical nutrition and train graduate students to apply methods of food assessment at the population level to be included in the parent grant’s Water-Energy-Food-Health nexus. The supplement will provide insight into the complex climate-agriculture-food-nutrition-health context and in relation to climate change impacts of low quality and quantity of drinking water. We have data collected on water use and access through the parent grant which this diet data will complement to help us understand the Water- Energy-Food-Heath Nexus within rural Jordan.
