Cette étude porte sur l’évolution des politiques d’approvisionnement en eau potable (AEP) en milieu rural en Afrique de l’Ouest francophone et sur les performances de la délégation des services d’eau en milieu rural. Dans de nombreux pays, il existe un fossé entre la théorie et la pratique, avec des modèles alternatifs de fourniture de services d’eau en milieu rural coexistant avec des arrangements informels, alors que les services auraient dû être délégués.

Performance and prospects of rural drinking water services in francophone West Africa
This study looks at the evolution of rural water supply policies in francophone West Africa and the performance of the delegation of rural water services. In many countries there is a gap between theory and practice, with alternative models for rural water services delivery co-existing with informal arrangements, where services should have been delegated.
Story of Change: Fit-for-purpose labs for monitoring and managing rural water supplies
In Nepal, Kenya and Bangladesh, researchers working with practitioners and local governments have established fit-for-purpose (FFP) laboratories to support reliable water quality monitoring and operational management of rural water systems
Hydrogeologic Constraints for Drinking Water Security in Southwest Coastal Bangladesh: Implications for Sustainable Development Goal 6.1
This article analyzes drinking water security in southwest coastal Bangladesh, through an in-depth field investigation. It reveals that the exponential growth of groundwater-based technologies, such as tube wells, does not necessarily indicate the actual safe drinking water coverage in coastal areas, due to complex hydrogeology with the high spatial variability of groundwater salinity risks.
Regional groundwater flow system characterization of volcanic aquifers in upper Awash using multiple approaches, central Ethiopia
This study uses electrical conductivity, temperature and isotope analysis to characterise the recharge, flow and discharge of volcanic aquifers in upper Awash Basin, Ethiopia.
Scaling up results-based funding for rural water services
In 2016, a results-based funding model was developed to improve the reliability of rural drinking water supply services in Kenya. The Water Services Maintenance Trust Fund (WSMTF) has tested a professional service delivery model in two counties and attracted new sources of results-based funds to guarantee water services in rural communities.
Spatio-temporal variability and potential health risks assessment of heavy metals in the surface water of Awash basin, Ethiopia
Increasing urbanization and industrialization in the Awash River basin, Ethiopia, is impacting water quality. Physico-chemical and heavy metal spatio-temporal variability and associated risks to human health and ecology were assessed across twenty sampling stations. Contamination indicators suggest variable but significant health risks to people exposed to untreated water in the sampled area, including cancer risk from heavy metals which enter basin waters due to human activities and natural erosion.
High-resolution synthetic population mapping for quantifying disparities in disaster impacts: An application in the Bangladesh Coastal Zone
In this study, the authors demonstrate how combining various modelling techniques could provide novel insights into the exposure of poor and vulnerable groups, which could help inform the emergency response after extreme events as well targeting adaptation options to those most in need of them.
Intra-seasonal rainfall and piped water revenue variability in rural Africa
Rainfall patterns influence water usage and revenue from user payments in rural Africa. The authors explore these dynamics by examining monthly rainfall against 4,888 records of rural piped water revenue in Ghana, Rwanda, and Uganda and quantifying revenue changes over 635 transitions between dry and wet seasons.
When Water Quality Crises Drive Change: A Comparative Analysis of the Policy Processes Behind Major Water Contamination Events
This study explores the delayed policy response to the arsenic crisis in Bangladesh through comparison with water contamination crises in other contexts (incl. included Escherichia coli O157:H7 and Campylobacter in Walkerton, Canada; lead and Legionella in Flint, Michigan, USA; and chromium-6 contamination in Hinkley, California, USA).
