The goal of this mini-cube is to focus on how water, sanitation and hygiene (WASH), coupled with nutritional conditions related to food access vary across the rural-urban gradient in Eastern Africa, and how each impacts malnutrition as measured by childhood stunting. It appears that malnutrition-induced childhood stunting is compounded by poor sanitation conditions, and that community-scale interventions to achieve improved sanitation can mitigate stunting effects and are more effective than interventions that target individuals. Building on our current work in Ecuador, Kenya and Ethiopia, we will define the components of the WASH-stunting pathway in both urban and rural settings. Products will include a literature review that we hope to develop into a peer-reviewed journal paper, and a field trial in Ethiopia. Preliminary results will serve as the basis for proposals to external funding agencies.
