This report presents a synthesis of published and ongoing research by REACH which explores the relationship between water security, climate and climate adaptation decisions. The report draws on findings from REACH research conducted in Sub-Saharan Africa and South Asia.

Optimizing rural drinking water supply infrastructure to account for spatial variations in groundwater quality and household welfare in Coastal Bangladesh
This study examines decision-making to invest in drinking water infrastructure in coastal Bangladesh, where increasing saline intrusion in aquifers intersects with high levels of poverty for the 20 million people living in the coastal region
Exploring water access in rural Kenya: narratives of social capital, gender inequalities and household water security in Kitui county
This study uses qualitative methods to examine how values embedded in social capital enable women and vulnerable groups in Kenya’s Kitui County, to cope with household water insecurity.
Natural and anthropogenic sources of salinity in the Awash River and Lake Beseka (Ethiopia): Modelling impacts of climate change and lake-river interactions
This study simulated chloride concentration in Ethioia’s Awash River Basin by taking both natural and anthropogenic sources of salinity into consideration. Future scenarios of climate change and Lake Beseka discharge were examined to assess the impact to the river water quality.
Report on findings from the Awash River basin
This report provides an update on REACH’s work in the Awash Basin up to November 2020, and introduces our programme of research from 2020-2024.
Petrography and Geochemistry of the Rocks in Lodwar, Kenya and their Influences on Groundwater Quality
This paper evaluates the influence of rock chemistry on groundwater quality in the region of Lodwar County, Kenya. Rock geochemistry influences groundwater quality and the aquifer processes of an area. Therefore, this study used conventional petrography and geochemistry techniques to measure the mineralogical compositions of 69 rock samples. The geological study area comprised of quartzo-feldspathic gneiss and biotite gneiss of the Precambrian basement, as well as sedimentary Turkana Grits and Holocene sediments, Tertiary volcanics comprising nepheline phonolites and augite basalts, alluvial deposits along the banks of major Streams and laggas. Quaternary sands also blanket much of the area. The results demonstrate that that geological factors and processes have location-specific influence on groundwater quality. These should be considered in aquifer water-quality studies and supply development across Africa’s vast ASAL regions.
Drinking water services in coastal Bangladesh
This report presents empirical evidence on the existing state of drinking water services in coastal Bangladesh, highlighting challenges and opportunities for reforms in the institutional design, information systems, and sustainable finances under the proposed ‘SafePani’ model.
Policy reform for safe drinking water service delivery in rural Bangladesh
As the Government sets out to revise the 1998 National Policy for Safe Water Supply and Sanitation, the ‘SafePani’ model proposes reforms in institutional design, sustainable finance, and information systems, to advance SDG 6.1.
Policy reform for safe drinking water service delivery in rural Bangladesh
This policy brief presents the SafePani model, a new institutional framework for rural water service delivery in Bangladesh.
Impact of Natural and Anthropogenic Stresses on Surface and Groundwater Supply Sources of the Upper Awash Sub-Basin, Central Ethiopia
A WEAP/MODFLOW model was used to evaluate the impacts of population growth, leakage, expansion of surface and groundwater supply schemes, and climate change scenarios up to the year 2030.
