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.

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.
Soil moisture spatio‑temporal variability under treated and untreated catchment conditions in a fragile tropical highland environment: implication for water security
This research article presents soil moisture variability as influenced by catchment management in the Blue Nile Highlands, Ethiopia. The authors show that improved catchment management can play a critical role in improving agricultural water security in rainfed systems by improving soil moisture availability and storage.
Assessing the effect of sustainable land management on improving water security in the Blue Nile Highlands: a paired catchment approach
This paper investigates the use of sustainable land management (SLM) practices over a 5 year catchment restoration effort in the Blue Nile Highlands, Ethiopia, analysing run off and soil moisture dynamics. It finds SLM interventions are capable of restoring natural hydrological functionality, and reducing nonproductive freshwater losses.
Geomorphic change in the Ganges– Brahmaputra–Meghna delta
More than 70% of large deltas are under threat from rising sea levels, subsidence and anthropogenic interferences, including the Ganges–Brahmaputra–Meghna (GBM) delta, the Earth’s largest and most populous delta system. This review describes GBM delta dynamics, examining these changes through the Drivers– Pressures–States–Impacts–Responses framework.
Engaging with the politics of climate resilience towards clean water and sanitation for all
In this article, world-leading water specialists from academic and practitioner communities reflect on, and share examples of, the importance of keeping people and politics at the centre of work on climate resilient water security.
Summary Report | Water Security for Climate Resilience
This Summary presents the main findings and recommendations of the Water Security for Climate Resilience Report.
Water Security for Climate Resilience Report
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.
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.
