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.

When Water Quality Crises Drive Change: A Comparative Analysis of the Policy Processes Behind Major Water Contamination Events
This paper explore the delayed policy response to the arsenic crisis in Bangladesh through comparison with water contamination crises in other contexts
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.
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.
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.
Modular, adaptive, and decentralised water infrastructure: promises and perils for water justice
This review summarises emerging realities for water insecurity in an era of disruption, and new developments that the authors call modular, adaptive, and decentralised (MAD) water infrastructure. These decentralised models require a justice-oriented framework to unlock the promise of sustainable access to safe, reliable, affordable water supply for a more mobile, just, and resilient world.
Negotiating spaces of marginality and independence: On women entrepreneurs within Ethiopian urbanization and water precarity
This research article analyses how women strive for and negotiate their independence through spatiality, and how services, specifically water, affect their ability to develop their business spaces. Using evidence from five studies conducted in the small town of Wukro, Ethiopia, the paper suggests water struggles should be analysed not only through the evaluation of water shortages and unequal geographical sectorization but also through the perspective of ‘water precarity’ (Sultana, 2020).
July–September rainfall in the Greater Horn of Africa: the combined influence of the Mascarene and South Atlantic highs
This climate dynamics research article investigates the relative influences of the Mascarene and South Atlantic highs on July-September rainfall, a key component of Ethiopia’s annual rainfall and source of variability. A covarying region in the Greater Horn of Africa is analysed using CHIRPS observed rainfall and the ERA5 reanalysis.
Piped water revenue and investment strategies in rural Africa
This article examines how water service delivery approaches impact revenue generated by user payments, and how infrastructure investment strategies can promote revenue and equity goals for rural piped water services.
