University of California at Berkeley conducted a desk review analysis of the effects of sanitation interventions on population health in Guatemala. By analyzing existing data in new ways, researchers at UC Berkeley are attempting to understand the relationships between population density, sanitation, and health outcomes.
RICE Institute conducted a desk review on the relationship between population density and sanitation interventions. The goal of this research is to more fully characterize the impact of WASH interventions in areas of high population density, given that urban populations are growing rapidly worldwide. RICE’s research compares the effect of sanitation interventions on health impacts across both high and low population density settings in India, Bangladesh, Cambodia, and Nigeria.
TRAction intends to fund an empirical study to assess the relationship between sanitation coverage and population density, within the context of an existing WASH development project. The research will address how varying degrees of access to basic sanitation affect the risk of diarrheal diseases and soil-transmitted helminth (STH) infections among children living in high-density, low-income settlements compared to similar access in lower density, low-income areas.
