Geoscience Africa
We aim to understand the geology, georesources, climate, hydrology and landscapes of critical regions in Africa, and to analyse how natural resources can be best harnessed for sustainable development.
We bring together African geoscience expertise in the Earth and Environmental Sciences with local partners and collaborators to meet the geoscientific challenges of Africa.
Africa is a very special continent. It features some of Earth’s oldest rocks, largest mineral and hydrocarbon deposits, and most extreme climates and environments. It is the cradle of humankind but has been particularly severely ravaged by colonialism since the 17th century. As a UK institution, we see it as a privilege, but also a particular responsibility, to contribute cross-disciplinary solutions to the continued development of the earth and environmental sciences in Africa. Particular areas of focus for us include sustainable mineral and hydrocarbon exploration, hydrology, paleoclimates, natural hazards and geoscience education and training.
Aims
We aim to understand the geology, georesources, climate, hydrology and landscapes of critical regions in Africa, to analyse how natural resources can be best harnessed for sustainable development, and how to strengthen resilience of people and society at all levels.
Research
Geoscience education and policy
We are working with partners including UNESCO, NEPAD, the African Union, the World Bank and major mining companies to develop and deliver online courses in prospectivity and sustainability mapping, to prepare graduates for roles in the minerals sector, and the development of industrial minerals and gemstones, with a focus on Malawi, Zimbabwe and South Africa. We are analysing sustainability and climate focused strategies across the continent to understand the geoscience skills opportunities and challenges they create. We also work closely with many African universities, including Midlands State University, Zimbabwe and the University of Zimbabwe; Chancellor college, University of Malawi; Stellenbosch University, South Africa and Rhodes University, South Africa.
Economic Geology
We use our state-of-the-art analytical facilities to help unravelling the origin of some of the world’s largest deposits of minerals and hydrocarbons, and to develop improved methods for sustainable and non-invasive exploration. Deposit types of particular focus include magmatic PGE-Ni-Cu and gold deposits, studied in more than a dozen countries within southern, central and west Africa.
Hydrology
We are working with partners across East Africa (including the Horn of Africa) and Central Africa to understand and predict water availability in dryland regions to support community-centred adaptation and resilience to climate change. Our work includes all aspects of the terrestrial water cycle and its interactions with society and ecology. Better understanding of present-day climate-hydrological interactions also enables us to explore how variable water availability influenced human evolution and dispersal in the region.
Paleoclimate
We apply a range of paleoclimate proxies, which tell us about past climatic and environmental variables such as terrestrial temperature, vegetation, precipitation and rainfall seasonality, sea surface temperature, wind patterns, river runoffs and the terrestrial and marine landscape. These coupled marine-terrestrial reconstructions are being used to understand the role climate had in shaping the evolution of new adaptations, the origin and extinction of early hominin species, and the emergence and livelihoods of our species, Homo sapiens.
Natural Hazards
Together with partners in Malawi we study fault systems in the southern East African Rift. These faults have the potential for hosting large and damaging earthquakes, and we map the location, orientation, and extent of active faults to constrain seismic hazard. We are integrating diverse evidence sources to characterise multi-hazard interrelationships in urban contexts (e.g., in Nairobi) and exploring disaster preparedness in the face of multiple hazards.
Medical geology
Looking at the human health impacts of bioreactive clay minerals both as a health hazard when ingested or as a potential natural antibacterial agent when dermally applied to wounds.
