ARISE: A Catalyst for Change
My name is Dr. Edem Mahu, a marine biogeochemist at the University of Ghana in the Department of Marine and Fisheries Sciences. Over the years, my journey as a researcher has been deeply enriched by the transformative support of the African Research Initiative for Scientific Excellence (ARISE), awarded by the African Academy of Sciences (AAS). This initiative has not only elevated my research but has also empowered me to build a legacy of scientific innovation and capacity-building in Ghana and across Africa.
As an early-career scientist, I faced significant challenges, particularly the lack of infrastructure for advanced research. Before ARISE, I often had to ship samples abroad for analysis, a process fraught with delays and high costs. This hampered my ability to conduct timely and impactful research.
In 2020, my career took a transformative turn when I became one of the principal investigators supported by ARISE. The programme provided funding that allowed me to establish Ghana’s first isotope ratio mass spectrometer laboratory—a groundbreaking achievement for marine science in the region. This state-of-the-art facility has enabled me to conduct advanced research, such as reconstructing climate history and assessing human impacts on marine ecosystems.
ARISE’s investment did not stop at infrastructure. It provided the resources and mentorship needed to scale my research and collaborate with peers across Africa. Today, my lab serves as a hub for researchers from Ghana and neighbouring countries like Nigeria, fostering regional collaboration and advancing marine science on the continent.
Achievements Enabled by ARISE
Revolutionizing Marine Science in Ghana
With ARISE support, I have advanced research into the ecological and human health risks of heavy metal pollution in Ghana’s coastal waters. My work has informed policy discussions on environmental protection and sustainable development.
The isotope ratio mass spectrometer has enabled me to conduct climate reconstruction studies, shedding light on the historical dynamics of marine ecosystems in the Gulf of Guinea. These insights are vital for understanding how to adapt to climate change.
ARISE funding has also supported the training of master’s and PhD students. I have mentored over 10 graduate students who are now contributing to marine science across Africa. This effort is building a pipeline of skilled researchers who will sustain the momentum in scientific excellence.
My lab has become a regional resource, hosting researchers and fostering partnerships with institutions across Africa. This collaborative approach is key to addressing shared challenges such as marine pollution, food security, and climate adaptation.
ARISE’s emphasis on inclusive science has empowered me to mentor young women pursuing careers in STEM. Through this initiative, I have championed efforts to break down barriers for women in marine science and create supportive environments for their success.
Building a Legacy of Impact
The impact of ARISE extends far beyond my individual achievements. ARISE is transforming Africa's research landscape by equipping scientists like me with the tools, funding, and networks needed to excel. The programme has shown that African scientists can lead groundbreaking research addressing local and global challenges with the right support.
Through ARISE, I have contributed to building Ghana’s capacity for marine science, strengthened regional collaboration, and inspired a new generation of researchers. This is not just a personal success—it is a collective victory for Africa’s scientific community.
Looking Ahead
While ARISE has been instrumental in enabling my achievements, the journey is far from over. Africa needs sustained investment in research infrastructure, funding, and talent retention to fully unlock its potential. Programmes like ARISE are a critical piece of this puzzle, but we must continue to expand these efforts.
To policymakers, funders, and fellow researchers: let us work together to build a robust science ecosystem that supports innovation, drives sustainable development, and retains Africa’s brightest minds. With initiatives like ARISE leading the way, I am confident that Africa’s future in science is brighter than ever.
About ARISE
The African Research Initiative for Scientific Excellence (ARISE), led by the African Academy of Sciences (AAS), is transforming Africa's research and innovation ecosystem. Launched in 2020 with €25 million in funding from the European Union and support from the Carnegie Corporation of New York, ARISE empowers African researchers to address pressing socio-economic challenges.
The programme supports nearly 600 early to mid-career researchers in 38 African countries through research grants, state-of-the-art equipment, and training opportunities. ARISE is building a legacy of competitive, pan-African research excellence, transforming the continent into a knowledge-based, innovation-led economy.
