Assessing the risks of water deficit in Central Africa

Host institution

The National Institute of Cartography (NIC)

Grant year


Project summary

Over recent decades, water availability has become an increasing challenge for west Africa, threatening domestic hygiene, agriculture, food security, and hydropower, and putting the lives of millions of people at risk. Dr Thierry C. Fotso-Nguemo, based at the National Institute of Cartography (NIC) in Yaoundé, Cameroon, will lead a team to evaluate how SRM might alter the effects of climate change on the hydro-climatology of major Central African river basins, including how that might affect irrigation and the filling of dams. Their insights will be essential in helping decision makers better plan, manage and govern water resources in the sub-region, as well as raising awareness of the risks and benefits associated with SRM.

The team

National Institute of Cartography
Thierry C. Fotso-Nguemo is a researcher at the Climate Change Research Laboratory (CCRL) of the National Institute of Cartography (NIC) in Yaoundé, Cameroon, which is a multidisciplinary research institute under the authority of the Ministry of Scientific Research and Innovation. His research focuses on the use of global and/or regional climate models to investigate the impact of anthropogenic global warming on climate variability, including extreme weather events, and their implications on socio-economic development sectors. He is a member of the CORDEX Central Africa analysis group, as well as an associate member of the Abdus Salam International Centre for Theoretical Physics (ICTP). He holds a PhD in atmospheric sciences from the University of Yaoundé.
National Institute of Cartography
Jean Pierre Nghonda is a researcher at the CCRL and a PhD student at the University of Maroua, Cameroon. He read physical geography, then specialised in climatology and tropical hydrology and had his skills enhanced at the International Institute for Geo-Information Science and Earth Observation (The Netherlands), thanks to a grant from the TIGER initiative under the Africa-European Space Agency’s programme. His current research is investigating the ways in which traditional knowledge systems can be used to aid understanding and management of shifts in the Sahel water cycle in Northern Cameroon near Lake Chad, and comparing this to modern scientific understanding of the processes at play.
National Institute of Cartography
Steven Chouto is a researcher with the CCRL. He is currently completing a PhD in physical geography at the University of Maroua (Cameroon). Prior to this, he completed a post-graduate specialisation in space science and technology at the African Regional Centre for Space Science and Technology in Morocco. During this time, he developed skills in statistical methods and geospatial scaling of earth science data. His interdisciplinary research focuses on the analysis of the vulnerability of socio-ecological systems to natural hazards around water resources affected by climate change, through spatial analysis of in situ, and large-scale geospatial and remote sensing data in cloud computing environments.
National Institute of Cartography
Flore Djuidje Kamogne is a PhD student in physical geography, with a specialisation in climatology at the University of Yaoundé 1 (Cameroon), and she is also a researcher at the CCRL. Her research focuses on agro-climatology to explore the impact of climate change on agricultural practices. She is also interested in understanding the dynamics of water resources in the context of climate change.
Institut of Research for Development (IRD)
Arona Diedhiou is the Director of Research at the Institute of Research for Development (IRD). He is based at the Institute of Environmental Geosciences (IGE) at the University Grenoble Alpes (UGA). He is hosted at the University Felix Houphouët Boigny (Ivory Coast) as Co-director of the International Joint Laboratory on the nexus between climate, water, agriculture and energy as part of the Climate Nexus Lab. He specialises in the African climate system and climate change in the tropics, and works within the context of several international programs on climate extremes and their drivers in Africa. He was a Lead Author of the IPCC Special Report on the impacts of 1.5°C of global warming and was also a Reviewer-Editor for the IPCC Assessment Report WG1/AR6.
National Institute of Cartography
Zéphirin Yepdo Djomou is a senior research officer at the NIC. His current research includes understanding the large-scale, spatio-temporal shifts of climatic zones and extreme weather conditions over Africa. He is involved in several research projects such as the Africa Low Emissions Development Strategies (Africa-LEDS) Cameroon, and IVAC, which deals with the production and dissemination of targeted information on climate variability in Cameroon. Prof Djomou holds a PhD in atmospheric sciences from the University of Yaoundé 1.
