The impacts of SRM on seasonal and intra-seasonal climate variability over East Africa

Host institution

Uganda National Meteorological Authority (UNMA)

Grant year


Project summary

Millions of people across East Africa rely on rain-fed agriculture for their survival, and are under increasing stress due to the effects of climate change. The deployment of SRM would offset an increase in global temperatures, and potentially reduce the risks of global warming, but its impact on East Africa’s seasonal and intra-seasonal climate is unclear. A team led by Dr Bob Alex Ogwang, from Uganda’s National Meteorological Authority, will explore how SRM might affect seasonal and intra-seasonal rainfall and temperatures, compared to the changes brought about by a shifting climate. Their results will bolster the region’s scientific contribution to global SRM policy discussions, whilst also encouraging further regional interdisciplinary scientific research in general.

He is also a visiting researcher at the University of Reading in the United Kingdom. His interests include sub-seasonal to seasonal climate variability, extreme climate events, and regional climate change. His current work includes understanding of the role of equatorial waves in influencing extreme precipitation over Equatorial Africa. He is the winner of the 2021 Ian James Award.
Makerere University
Catherine Mulinde is a climate and environment scientist, and for the last 15 years, she has been a lecturer at Makerere University. Catherine holds a PhD in climate science and adaptation, and her research interests also include geography, environment sciences, and agriculture. She is widely published across these topics and has developed her expertise in climate change modelling, weather forecasting, climate extremes and farming systems analysis, econometrics, community adaptation and environmental impact assessments. She has collaborated with several funding agencies, national and international institutions, and research projects and consultancies, including with Makerere University, the Government of Uganda and non-governmental organisations.

Alex Nimusiima is a senior lecturer at Makerere University. He was a team member of the adaptation and vulnerability group that produced the Third National Communication of Uganda to the United Nations Framework Convention on Climate Change (UNFCCC). He has also participated in a FAO-funded project on climate change modelling in Uganda, which produced a climate atlas for the country. He is also a member of the CORDEX Africa Analysis Group that has published extensively on climate dynamics and their impacts on the African continent. He has also published over 21 research articles in peer-reviewed journals.
