Completed Projects

Research Area: Food security
In the northern region of Benin, in the Sudano-Sahel region of West Africa, the dry season between rains can last six to nine months at a time. Because most of Benin’s smallholder farmers rely on rain-fed agriculture for both their food supply and their income, the dry season can be a time not only of food insecurity but of poverty, illness and malnutrition. Groundwater is often too deep for traditional wells to reach, and the high price of fuel makes it difficult to rely on electric irrigation pumps.
Research Area: Urban service delivery, Sanitation & wastewater
Better understanding of how household and community sanitation affects child exposure to fecal contamination and diarrheal pathogens could improve the design of sanitation interventions in low-income urban communities. This project includes a case-control study to assess observable household and community sanitation characteristics as risk factors for child clinical diarrhea cases. It also includes an in-depth microbial sampling component to measure environmental fecal contamination among households with varying sanitation service levels.
Research Area: Technology development
In Kibera slum in Nairobi, Kenya, clean water is sold, but residents often don’t know in advance where to buy it or how much it costs. Therefore, the time expenditure for finding and fetching clean water can be substantial. M-Maji aims to leverage the power of mobile technology to bypass traditional barriers to clean water – specifically information barriers.
Research Area: Human health & medicine, Sanitation & wastewater
During the first two years of life, children born in low-income countries are at risk for enteric infections due to poor water quality, sanitation conditions, and caregiver handwashing practices (WASH).
Research Area: Sanitation & wastewater
This project used multi-scale modeling of health behavior choices and integrated theoretical frameworks and methodologies from behavioral sciences, epidemiology, and microeconomics to better understand behavior change processes related to water, sanitation, hygiene and health.
