Ranaivo Rasolofoson: Forests Moderate the Effectiveness of Water Quality Improvement Efforts at Reducing Childhood Diarrhea
Environmental degradation has been associated with increased burden of diseases such as malaria, diarrhea, and malnutrition. As a result, some have argued that continuing ecosystem change could undermine successes in global health investments. Here we conduct one of the first empirical studies to investigate this concern. Child deaths due to diarrhea have more than halved since the year 2000, partly due to increased access to improved water, sanitation and hygiene (WASH). We examine how the effectiveness of WASH efforts may vary as a function of upstream watershed condition. We use data on occurrence of diarrhea, types of household drinking water sources, and point-of-use water treatment methods from the Demographic and Health Surveys for six low and lower-middle-income countries.
Ranaivo is a Gund Affiliate and a Postdoctoral Associate at Cornell University. He interested in investigating the impacts of environmental programs and environmental changes on different human well-being and environmental outcomes. He has looked at the impacts of community forest management and protected areas on deforestation, economic, and subjective human well-being in Madagascar. Ranaivo has also examined the links between forests, child nutrition, and health in developing countries. At Cornell, Ranaivo explores links between fishery and child development in the areas around Lake Victoria, Kenya.
