Gender disparities in water-related knowledge, perceptions, and governance in rural Ghana
Gender inequalities remain persistent across water-related activities in labor division and decision-making disparities. Yet, our understanding of these dynamics remains limited to generalized narratives. This study examined gender disparities in water knowledge, perceptions, and governance in rural Ghana, drawing from focus group discussions (FGDs) conducted between January and March 2023. Using both qualitative thematic analysis and Natural Lan…
Will Households Invest in Safe Sanitation? Results from an Experimental Demand Trial in Nakuru, Kenya
Unsafe sanitation is an increasing public health concern for rapidly expanding cities in low-income countries. Understanding household demand for improved sanitation infrastructure is critical for planning effective sanitation investments. In this study, we compared the stated and revealed willingness to pay (WTP) for high-quality, pour-flush latrines among households in low-income areas in the city of Nakuru, Kenya. We found that stated WTP for …
Policy Diffusion in the Rural Sanitation Sector
Worldwide, 892 million people practice open defecation, most of whom live in rural areas of South Asia and Sub-Saharan Africa. Community-Led Total Sanitation (CLTS) is the most widely deployed approach to generate demand for, and use of sanitation facilities. CLTS relies on behavioral change and community self-enforcement to end open defecation. Since its genesis in Bangladesh in 1999, CLTS has spread to approximately 60 countries, mostly in Asia…
Measuring the Impacts of Water Safety Plans in the Asia-Pacific Region
This study investigated the effectiveness of Water Safety Plans (WSP) implemented in 99 water supply systems across 12 countries in the Asia-Pacific region. An impact assessment methodology including 36 indicators was developed based on a conceptual framework proposed by the Center for Disease Control (CDC) and before/after data were collected between November 2014 and June 2016. WSPs were associated with infrastructure improvements at the vast m…
Cross-subsidies for improved sanitation in low income settlements
Most residents of the developing world do not have access to safely managed sanitation services, and large financial investments are required to address this need. Here we evaluate surcharges on water/sewerage tariffs as an option for supporting these investments in low-income neighborhoods. We investigated willingness-to-pay (WTP) for a pro-poor sanitation surcharge among customers of two urban water utilities in Kenya. Applying qualitative and …
Can Sanitary Surveys Replace Water Quality Testing? Evidence from Kisii, Kenya
Information about the quality of rural drinking water sources can be used to manage their safety and mitigate risks to health. Sanitary surveys, which are observational checklists to assess hazards present at water sources, are simpler to conduct than microbial tests. We assessed whether sanitary survey results were associated with measured indicator bacteria levels in rural drinking water sources in Kisii Central, Kenya. Overall, thermotolerant …
To What Extent is Drinking Water Tested in Sub-Saharan Africa? A Comparative Analysis of Regulated Water Quality Monitoring
Water quality information is important for guiding water safety management and preventing water-related diseases. To assess the current status of regulated water quality monitoring in sub-Saharan Africa, we evaluated testing programs for fecal contamination in 72 institutions (water suppliers and public health agencies) across 10 countries. Data were collected through written surveys, in-person interviews, and analysis of microbial water quality …
When Are Mobile Phones Useful for Water Quality Data Collection? An Analysis of Data Flows and ICT Applications among Regulated Monitoring Institutions in Sub-Saharan Africa
Water quality monitoring is important for identifying public health risks and ensuring water safety. However, even when water sources are tested, many institutions struggle to access data for immediate action or long-term decision-making. We analyzed water testing structures among 26 regulated water suppliers and public health surveillance agencies across six African countries and identified four water quality data management typologies. Within e…
