This brief lays out options to better monitor and manage groundwater use, and to improve the conjunctive use of surface and groundwater to support sustainability for Addis Ababa’s water supplies.

Effects of chronic exposure to arsenic on the fecal carriage of antibiotic-resistant Escherichia coli among people in rural Bangladesh
Antibiotic resistance is a leading cause of hospitalization and death worldwide. Heavy metals such as arsenic have been shown to drive co-selection of antibiotic resistance, suggesting arsenic-contaminated drinking water is a risk factor for antibiotic resistance carriage. By collecting drinking water and stool from mothers and their children (<1 year), the study aimed to determine the prevalence and abundance of antibiotic-resistant Escherichia coli among people and drinking water in high and low arsenic-contaminated areas of Bangladesh. The positive association detected between arsenic exposure and antibiotic resistance carriage among children in arsenic-affected areas in Bangladesh is an important public health concern that warrants redoubling efforts to reduce arsenic exposure.
Improving the Reliability of Water Service Delivery in Rural Kenya through Professionalized Maintenance: A System Dynamics Perspective
This study applies system dynamics modeling to assess the potential impact of scaling up professionalized maintenance services on piped water systems in Kitui County, Kenya. The study results show that over a
10 year simulation, calibrated with 21 months of empirical data and based on a range of key assumptions, delivery of professionalized maintenance services across the county may increase countywide functionality rates from 54% to over 83%, leading to a 67% increase in water production.
Water policy, politics, and practice: The case of Kitui County, Kenya
This article uses an action-orientated knowledge framework to consider types of knowledge produced through rural water “policy experiments” in Kitui County, Kenya over the past 10 years. Actionable recommendations for the further development of county-level water policy include: 1) ensure local ownership of the policy-making process whilst enabling appropriate technical and legal support; 2) take long timeframes of institutional change into account in donor programming; and 3) establish water, sanitation and hygiene forums that bring diverse actors within the sector together to build cohesion, facilitate knowledge exchange, enable collaborative learning, and deliver action.
Equitable urban water security: beyond connections on premises
This study investigates to what extent urban water security is equitable in a small town in Northern Ethiopia with almost uniform access to piped water services. Development of a household water insecurity index considering issues of quality, quantity, and reliability, demonstrated high spatial variability in water security between households connected to the piped water system.
Evaluation of System-Level, Passive Chlorination in Gravity-Fed Piped Water Systems in Rural Nepal
This article presents a nonrandomized evaluation of two passive chlorination technologies for system-level water treatment in use in western Nepal. Our findings suggest that whilst safe storage, service delivery models, and reliable supply chains are required, passive chlorination technologies have the potential to radically improve rural household access to safely managed water.
Gender gaps in sustainable land management and implications for agricultural productivity: Evidence from Ethiopia
This discussion paper looks at whether a large-scale watershed program promoting sustainable land management (SLM) in Ethiopia increases adoption of SLM in male-headed vs female-headed households. Our findings show that the SLM program significantly increased adoption of SLM practices (soil bunds, stone terraces, mulching) in male-headed households but that adoption was centered on jointly owned plots and male-owned plots, with no significant adoption on women-owned plots.
Key stakeholders and actions to address Lake Beseka’s challenges in Ethiopia: A social network approach
This discussion paper uses a social network approach to examine key actors, challenges and sustainable solutions to manage Lake Beseka, Ethiopia. The study suggests that developing multi-stakeholder partnerships or platforms across most influential and most affected actors could foster the development of more integrated solutions that support the different stakeholders in the lake catchment area and the Awash River Basin.
Observations of the Turkana Jet and the East African Dry Tropics
This article presents research from a field campaign in northwest Kenya on the Turkana Low Level jet, an intrinsic part of the African climate system and principle method of water vapor transport to the African interior from the Indian Ocean. Measured for the first time in 40 years, this dataset presents new evidence on the Turkana jet, and creates an opportunity to better understand regional dynamics in one of the most data-sparse regions in the world.
Incentivizing clean water collection during rainfall to reduce disease in rural sub-Saharan Africa with weather dependent pricing
This article proposes a new pricing mechanism for ‘water ATMs’, made possible with pre-payment and remote sensing, where prices adjust during rainy seasons to incentivise the continued use of clean water sources. The authors estimate cost per capita and cost per disability-adjusted life year averted, resulting in values which compare favourably with other water quality interventions.
