This paper uses an ensemble of high-resolution global drought datasets to analyse the extent to which a key driver, atmospheric evaporative demand (AED) impacts drought magnitude, frequency, duration and location. It finds that AED has increased drought severity by an average of 40% globally and that AED has an increasingly important role in driving severe droughts. This tendency will likely continue under future global warming scenarios.

REACH Story of Change: SafePani – Public finance to support safe drinking water in Bangladesh
The SafePani model guarantees reliable drinking water services, free from faecal contamination, to rural schools (primary and secondary) and community clinics in rural Bangladesh. SafePani represents a change in National WASH Policy and national planning in Bangladesh. For the first time, safe drinking water services will be ensured in public schools and community clinics with a sustainable funding model to ensure accountable service delivery to 2030.
Climate resilience and water security – Key messages from the REACH Kenya programme 2015-2024
This report from the Institute for Climate Change and Adaptation (ICCA) at the University of Nairobi, Kenya provides a summary of key messages from research conducted under the REACH Kenya programme (2015-2024).
Ten years of REACH Kenya
A brief overview of work by the REACH programme in Kenya on interlinked groundwater systems, institutions, water quality management and reducing inequalities, illustrating milestones in the Kitui and Turkana Water Security Observatories.
Rethinking responses to the world’s water crises
This perspective paper in Nature Sustainability reframes responses to mitigating the world’s water crises using a ‘beyond growth’ framing. Beyond growth is systems thinking that prioritizes the most disadvantaged. It seeks to decouple economic growth from environmental degradation by overcoming policy capture and inertia and by fostering place-based and justice-principled institutional changes.
Unpacking the progression of climate uncertainty into precarity in the urban context of drylands: the case of floods in Lodwar, Turkana
Climate uncertainty has always existed both as a socio-ecological reality for pastoralists living with climate variability in drylands and as a component within climate modelling. Despite this, there is little consideration as to the experiences of poor people in the urban drylands living with intensified hazards. In response, this paper discusses an emerging conceptual nexus of uncertainty and precarity, using the example of flood disaster governance in Lodwar, Kenya.
Assessing flooding extent and potential exposure to river pollution from urbanizing peripheral rivers within Greater Dhaka watershed
This study looked into the water quality and flooding situation of Greater Dhaka for two successive monsoons through extensive river sampling coupled with the estimation of flooded area and exposed population using remote sensing tools.
Climate–water crises: critically engaging relational, spatial, and temporal dimensions
This paper examines the political nature of water crisis discourses and their influence on responses to water and climate challenges. It argues that crisis definitions are not universally agreed upon but are shaped by authority, legitimacy, and the ability to mobilize resources.
REACH Story of Change: Building drought resilience in Ethiopian river basins
Through the BRIGHT programme, REACH partner WLRC will build upon and scale up its research on water resources management, climate science, water quality and inequalities in Ethiopia to benefit an estimated 2.5 million people directly, and over 50 million people indirectly. This Story of Change reflects on the partnerships and processes that have facilitated this success for WLRC and for Ethiopia.
Resolving the Turkana Jet—Impact of Model Resolution in Simulating Channel Flow and Inversions
The Turkana Jet plays a pivotal role in the meteorology of East Africa and owes its existence to both large-scale dynamics and the representation of intricate local-scale processes. However, much of our understanding of the jet relies on reanalysis, and these along with climate models that produce important projections do not represent these local-scale processes. This study systematically investigates the impact of changing model horizontal and vertical resolution in simulating the Turkana Jet, and associated local and large-scale processes.
