Hydrologic Extremes in a Changing Climate: a Review of Extremes in East Africa

This review presents recent research on drivers and typologies of climate extremes across different East African geographies. Droughts and floods remain the major challenges of the region. There are improvements in forecasting these extremes, but further research is required to improve understanding of key drivers and improve information provision for risk-based decision-making.

Global high-resolution drought indices for 1981–2022

Droughts are one of the most complex and devastating natural disasters and high-resolution data has proven essential in helping monitor their characteristics. This study has developed four high-resolution drought records based on the standardized precipitation evaporation index (SPEI) from 1981–2022. These datasets provide greater insight into drought patterns on varying scales, with potential benefits for the development of site-specific adaptation measures.

Story of Change: Turkana Jet research unlocks new understanding of East African droughts

The strength of the Turkana Jet – a wind feature which carries water vapour from the Indian Ocean across East Africa to Central Africa – is underestimated in current weather and climate models. New observations of the jet by researchers from the Kenya Met Department, the University of Nairobi and the University of Oxford have been used as a benchmark for UK Met Office forecasting models for East Africa.

Story of Change: Open source tools and skills for climate information flows

Reducing barriers to sharing and making use of climate information is vital for climate resilience. In Ethiopia’s Awash Basin, REACH partners have been working together to build tools to facilitate the use of climate data from weather and streamflow gauging stations. Weekly collaborative coding sessions form a long-term capacity building interaction.

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.

Participatory water resource management

A para-hydrology initiative in two regions of Ethiopia trained citizen scientists to collect quantitative data on rural hydrological systems. The data has been successfully used in several peer-reviewed studies to predict and assess the impact of sustainable land management interventions.

Protecting groundwater for climate resilience and water security in Turkana

In Turkana County, research by the University of Nairobi around Lodwar’s underlying aquifers is addressing critical data and knowledge gaps. Groundwater quality mapping indicates areas with poor groundwater quality to inform water infrastructure investments. This work contributing to new policy and practice to protect the Lodwar Alluvial Aquifer System and enhance resilience to climate risks.
