A new study led by DSI resident faculty member Kyle Davis examined survey data from more than 9,000 rural communities comprising more than 70,000 households in 26 countries in the Global South, a designation given to 134 states from Central and South America, Africa, Asia and Oceania. They then combined that data with global georeferenced datasets on irrigation infrastructure changes and found that dietary improvements vary depending on several factors, and the areas where irrigation expansion occurs do not automatically see an increase in food security simply because that area is growing more crops. This picture was taken during their dry season fieldwork in central Nigeria last March.
