Dr Tafadzwa Maramura: Leading the Fight for Clean Water Access in Africa
Dr Tafadzwa Clementine Maramura has dedicated her academic career to tackling one of the continent’s most urgent challenges — sustainable water governance
As Africa grapples with deepening water insecurity, a trailblazing researcher at the University of the Free State (UFS) is stepping into the global spotlight with a mission: to ensure every African has access to clean, safe water.
Dr Tafadzwa Clementine Maramura, a Senior Lecturer and NRF-Rated Researcher in the Department of Public Administration and Management at UFS, has dedicated her academic career to tackling one of the continent’s most urgent challenges — sustainable water governance. Her commitment was recently recognised with a historic appointment as the first black African woman to serve as Secretary of the Institutional Governance and Regulations Framework, a specialist subgroup within the International Water Association (IWA).
“Water is a basic human right, you can survive without electricity and other luxuries, but not without water. Each time you brush your teeth or flush your toilet with at least 15 litres of clean water or you are watering your garden with clean water, there are people that actually don’t have access to basic drinking water,” said Dr Maramura in a statement emailed to EdPublica.
“My research focuses on water governance and sustainable service delivery, public policies, and the green economy in the African, as well as the South African, context
The statistics underscore the urgency. According to Greenpeace, more than 1.34 billion Africans — over 90% of the continent’s population — face some form of water insecurity. The United Nations World Water Development Report 2024 also reports that 2.2 billion people worldwide lack access to safely managed drinking water.
Dr Maramura’s research is rooted in understanding how governments, particularly in Africa, can bridge this glaring gap. “My research focuses on water governance and sustainable service delivery, public policies, and the green economy in the African, as well as the South African, context,” she explained. “What I found is interesting and really saddening at the same time. When you break it down, you realise that one in every three people in Africa don’t have access to potable water.”
But for Dr Maramura, this issue is more than a policy problem — it’s a deeply personal and gendered one. “Access to clean water is not just a basic need; it is a matter of dignity, equality, and survival. As a young African woman, through my research, I see first-hand how the burden of water scarcity falls disproportionately on women and girls, robbing us as women, of education, economic opportunities, and health.”
“But we are not just victims – we are leaders in this fight. By empowering women and investing in sustainable water solutions, we can transform our communities and break the cycle of poverty. The time for action is now because water is life, and every African deserves it.”
Her upcoming book chapters, to be released in June, explore the water-health nexus in fragile states — aligning two of the Sustainable Development Goals (SDGs): Goal 3 (Good Health and Well-being) and Goal 6 (Clean Water and Sanitation). She stresses the interconnectivity of these issues.
“You cannot solve problems in isolation; you cannot look at the water problem in isolation. If you have a water problem, you have a health and education problem because kids can’t go to school if there is no water. Hospitals can’t function when there is no water,” she said. “How can we ensure that we merge the two together and ensure researchers working on health and water can find common ground to address any challenges arising from the lack of water so that we don’t have these health issues?”
Despite being an upper-middle-income country, South Africa continues to face major water delivery issues, especially in rural and impoverished areas. Millions still rely on ventilated pit latrines due to lack of access to modern sanitation.

Dr Maramura believes there is no one-size-fits-all solution but emphasizes a collaborative, inclusive approach. “There is work that needs to be done. The government, private sector, the communities, as well as other role players need to work together. South Africa is a water-stressed country with rainfall below the global average. We realised that we have scarce groundwater resources.”
She calls on communities to become more informed and involved. “The community needs to understand, participate, and be aware of how much damage we can do by just drilling boreholes and digging wells.”
On the role of the private sector, she notes: “They need to know what it is that they can do to ensure that they also play a part through their corporate social responsibility and philanthropic dimensions in assisting the community.”
And for government, she adds: “The policies are there. The government needs to consult with the communities, the private sector, and all other relevant stakeholders. They need to involve affected communities and after consultations, they need to engage these communities because they understand their problem best.”
Through her research, advocacy, and international leadership, Dr Maramura is not only asking the hard questions about water governance — she’s working to reshape the answers for the future of Africa

Rewriting cancer: Ankita Bansal’s quest to decode tumour metabolism
From aging research to precision cancer therapeutics, Ankita Bansal’s work sits at the intersection of metabolism, technology, and patient-centred science—seeking to transform how cancer is detected and treated in India
Scientist Ankita Bansal is investigating cancer metabolism to uncover new pathways for precision cancer therapies and early detection. Her research aims to make cancer treatment more personalised, accessible, and effective for Indian patients.
In the evolving landscape of cancer research, where breakthroughs increasingly depend on understanding the invisible workings of cells, metabolism is emerging as one of the most powerful frontiers. At the centre of this shift is Dr Ankita Bansal—scientist, educator, and one of the new voices shaping India’s precision medicine ecosystem. As part of Education Publica’s ‘Women in Science’ series, Bansal represents a generation of researchers redefining not just what science discovers, but how it translates into real-world impact. An Assistant Professor at Jio Institute, Mumbai and recipient of the prestigious Ramalingaswami Re-entry Fellowship, her work focuses on decoding how cancer cells reprogram their metabolism—and how these hidden dependencies can be turned into targeted, patient-specific therapies. Trained across leading global institutions, Bansal’s scientific journey spans aging biology to cancer metabolism, united by a single question: how do we move from understanding disease to meaningfully improving lives? Her research now centres on identifying metabolic signatures unique to Indian patients, with the aim of building scalable, accessible precision therapeutics. At a time when India is positioning itself as a hub for translational science, Bansal’s work sits at a critical intersection—where biology meets technology, and where discovery is measured not just in publications, but in its potential to reach patients.
From Cells to Systems: Rethinking Cancer with Ankita Bansal
Ankita Bansal is exploring how cancer cells rewire their metabolism – unlocking new pathways for precision therapies tailored to Indian patients

What first sparked your curiosity about biology – and was there a moment when you knew research was the path you wanted to take?
It started with simple observations and asking “why?” Over time, that curiosity deepened into a desire to understand why living systems behave the way they do. I began tinkering with home experiments to tease things apart, though I never actually set out to become a researcher. I simply followed my instinct to test ideas and see what happens when you change a variable. It was only much later that I realized what I had been doing all along had a formal name: research.

During your PhD, your work showed that living longer and living healthier are not necessarily driven by the same genes. How did that discovery change the way you think about aging – and about what science should aim for?
Longevity without quality of life is not worth aspiring to. Healthspan is about independence, resilience, and the ability to engage with the world—it isn’t just a fixed number of years on a chart. This philosophy carries directly into my cancer work, where improving how people live, staying in remission, and catching cancer early matters as much as extending survival.
Science operates the same way. It is not just about metrics—publications, h-index, or grants—but the broader ecosystem: the people, the communities it touches, and how it shapes society.
Decoding Cancer Metabolism for Better Care
You’ve worked across systems from C. elegans to cancer cells. How has this shaped you as a scientist?
Training in C. elegans grounded me in systems biology and metabolism, constantly reminding me that disease is rarely a single-gene or single-pathway problem. Moving into cancer research reinforced the complexity of biological networks and the importance of thinking at the level of the whole organism. This journey shaped me into a scientist who views disease as a dynamic interaction between metabolism, environment, and time, rather than an isolated molecular event.

What fascinates you most about targeting cancer through its metabolism rather than more traditional approaches?
Cancer cells are highly adaptable, yet they remain dependent on specific metabolic sources. That paradox is what fascinates me; that dependency is a vulnerability we can exploit. Metabolism fuels growth. A cancer cell can carry every genetic mutation imaginable, but without access to specific metabolic building blocks, it cannot sustain itself.
It also opens questions beyond treatment: Why do some cancers stay in remission while others metastasize? What metabolic signatures appear early enough to catch a tumor before it becomes a clinical problem? Understanding these dependencies allows us to build early detection approaches that are scalable and accessible to broader populations.
Are there experiences from your global training that influence how you mentor students or run your lab?
If you cannot explain your science to a ten-year-old or a ninety-year-old grandmother, the project might not be good enough. In my lab, I want to train scientists who communicate well, take ownership, and think like mavericks—be the goat, not the sheep.

It is okay to fail, provided you learn during the process. I want people who question assumptions and feel safe doing so. This culture can be difficult to implement in India, where deference runs deep in academic structures, but that makes it all the more important to try.
Why is the gap between academic discovery and patient-ready products still so wide – and what needs to change?
The biggest misconception is that academia and patient-ready products exist in separate silos. They don’t; they exist on a continuum. While this is a global problem, it is particularly acute in India. Academia rewards novelty, while translation requires scalability and collaboration. You cannot simply license a ready technology and call it translation; you have to be part of the process from day one. Academia must take real ownership in nation-building, with the patient’s needs as the starting point, not an afterthought. Scientists, clinicians, industry, and policymakers need to be in the room together far earlier than they currently are.
Building a research lab from the ground up is no small task. As a woman leading a lab, what challenges have surprised you the most?
The juggling act that no one adequately prepares you for: running a competitive research program while raising a family. In India, the lack of high-quality childcare and reliable after-school programs is a significant challenge. It is a major hurdle that directly affects productivity and well-being. Being open about these realities matters, because pretending they don’t exist helps no one.

Gender disparities in science are still very visible in India. Where do you see genuine opportunities for change?
Every day is better than the last. Things are genuinely improving, and I don’t want to paint a picture darker than reality. The most persistent barriers remain inadequate childcare infrastructure and the “two-body problem.” Beyond that, there are no impossible bottlenecks. The trajectory is positive. The key is to keep making the case that these structural issues are solvable through dialogue and goodwill.
How can Indian institutions better support women in science?
We need childcare infrastructure, flexible timelines, and open communication channels. These should be framed not as “accommodations,” but as essential investments in retaining top-tier talent.
Did role models play a part in your journey?
My grandmother pursued a double MA after marriage and showed me that learning has no expiration date. My mother embodied the resilience required of a working woman, and my father taught me that success comes through sacrifice. My PhD mentor ignited my passion for research, even while facing her own health challenges, shaping my approach to science with both rigor and empathy. I also value the scientific dialogue I share with my husband, a scientist-entrepreneur whose translational outlook broadens my perspective.
Visibility matters. When women scientists share not only their achievements but also their doubts and unconventional paths, the journey becomes more accessible. There is no single template for success.

What excites you most about building a precision therapeutics lab in India right now?
Our time has begun. India is at a unique point in its trajectory—our Amrit Kaal. We have growing technological capacity, vast patient populations, and massive unmet clinical needs. Out-of-the-box thinking is now highly sought after. Translating discoveries into affordable, scalable solutions that directly impact patients is what motivates me every morning.
Looking ahead a decade, what legacy do you hope your work leaves behind?
I hope to leave behind frameworks that integrate metabolism, technology, and clinical insight to revolutionize early cancer detection. More importantly, I hope to foster a culture where science is patient-centered first—where we start with the patient’s needs, not the publication, and build everything outward from there.

In this edition of Women in Science, Education Publica introduces Prof. Le Roux, a leading behavioural ecologist and Assistant Dean in the Faculty of Natural and Agricultural Sciences, and Associate Professor in the Department of Zoology and Entomology at the University of the Free State. Her work spans biodiversity, mountain ecosystems, and the escalating threat of wildlife mortality on roads. In this conversation, she discusses what’s driving rising roadkill risks in Africa’s mountains, how vulnerable species are being affected, and why conservation planning must rapidly evolve to protect these fragile ecosystems. Women in Science is a recurring Education Publica column profiling women scientists from around the world — their work, journeys, and impact.
You’ve dedicated your career to behavioural ecology and zoological sciences. What inspired you to pursue this path, and how has your journey shaped the way you approach issues like wildlife conservation and mountain biodiversity?
I’ve always loved being out in nature, ever since the first time my father took me for a hike up Table Mountain. Growing up, I experienced first-hand how wild animals and wilderness can be good for the soul (not just for the planet and for our physical health) – and then, as an adult, I saw in Europe and North America how very little wildness remains over there. This has really driven it home to me that we, on this continent, have very precious, living resources that we need to protect – and these resources are particularly unique in mountains. Disregarding this in favour of mining and other capitalistic ventures is really just speeding us along to a dystopian future.
Your research highlights the growing risk of roadkill in mountainous regions, particularly for endangered and vulnerable species. How is the expansion of road networks affecting wildlife in these areas?
Quite simply, these areas were previously less accessible to humans and vehicles, and the expanding road networks are changing that equation. Species at high altitudes now become more exposed to potential invasive species (which humans transport deliberately or accidentally) and collisions with vehicles. Our vehicles move far faster than natural predators do, so escaping the risk of oncoming traffic is not something any species is particularly adapted to. Populations will need to learn to avoid traffic and/or roads, if at all possible. This is not usually possible.

You mentioned that certain species, such as African wild dogs, lions, and elephants, are particularly vulnerable to roadkill. How do IUCN categories help frame the urgency of this problem?
The IUCN sets the global standard for us to understand which species to focus on in terms of conservation efforts. Knowing that nearly 8% of the mammals killed in mountains were of conservation concern, we must realise that we cannot simply ignore the risk. We are not just killing common species—we are killing species already at risk because of hunting pressure, climate change, and other threats.
Your findings show that amphibians are killed at the highest rate in mountainous regions, while mammals face greater risk in low-lying areas. What explains this difference?
It is difficult to answer because there is very limited data on population sizes of amphibians and mammals at different altitudes. Mountains provide more variation in microhabitats, so there may be pockets of ideal amphibian habitats with more freshwater and cooler microclimates. When a road cuts through such a pocket, a single car could kill dozens of amphibians at the “right” time. This should be studied further. These microclimates do not affect large mammals in the same way. It is also unclear whether mammals are killed more in low-lying areas because of more vehicles or more mammals.
Many small species are killed simply because they are less visible. Is there a broader societal or policy bias that undervalues smaller species?
Humans have an affinity for larger, charismatic species. However, the patterns are not only due to our personal biases—it is also practical. Drivers see larger animals more readily and avoid collisions because of potential damage to vehicles. Small animals are easier to disregard. Some drivers even deliberately kill snakes, but this did not create a large spike in the dataset. With effective communication, we could make drivers pay more attention to small but “special” species. We can change our behaviour.

Unpredictable weather patterns and the topography of mountain roads contribute to wildlife-vehicle collisions. How can infrastructure or road design help?
Mitigation often involves wildlife crossing structures—overpasses or underpasses—and warning signs in high-risk zones. For this to work in mountains, planners need to identify these high-risk zones and determine which structures or traffic-calming interventions are feasible. This will be a unique challenge in mountain environments.
Your study, covering 10 countries and spanning more than five decades of data, reveals major gaps in data collection. What are the most pressing gaps?
There are vast gaps in our information on population sizes and densities of vertebrate species in most African countries. If you look at the Map of Life, you’ll see how little biodiversity data we have from central and west Africa. We also found no roadkill studies in these large regions. We need to support scientists in those countries to investigate the challenges and potential solutions.
Mountain regions host unique biodiversity. How does roadkill threaten these rare or endemic species?
Because of the topography and history of mountains, they frequently host critical, unique biodiversity. Many are biodiversity hotspots. These endemic species cannot easily escape climate or anthropogenic change because physical barriers limit movement. There is also only so far “up” they can move. This is different in lowlands. Roads bring a new threat to species already vulnerable due to climate change.

Data collection on roadkill is often inconsistent. What needs to change to get a more accurate picture of the crisis?
It would be helpful if we had an international body to coordinate monitoring of roadkill risk, but I am not aware of such a body. It is not a methodological issue.
How can governments and conservation groups balance infrastructure development with protection of vulnerable species?
City planners, municipalities, and ecologists need to collaborate. Rather than relying solely on Environmental Impact Assessments, ideas for green spaces, wildlife corridors, and ecological connectivity should be included at the design stage of new developments. Such planning benefits environmental health and human wellbeing. Architects and engineers should also be encouraged to “think green” from the start.
What urgent actions are needed from both the scientific community and the public?
Identifying roadkill hotspots is essential as a first step. There are many areas where roadkill risk is lower, so we need to know where to focus mitigation measures.

Women in STEM Need Systemic Change
Stay committed, stay curious, and never underestimate the impact your work can have on the world
Despite notable gains in women’s participation in science careers in South Africa, women remain underrepresented across STEM fields. While more women are graduating from universities, studies continue to show that men dominate science, technology, engineering, and mathematics careers — a gap that is even more pronounced among Black women. Although women form the majority of young university graduates nationally, only about 13% of STEM graduates are women, and Black women remain significantly underrepresented in senior academic and research leadership positions.
These disparities stem from systemic barriers including gender bias, limited access to mentorship, and inconsistent availability of resources. Such obstacles continue to hinder the full and equitable participation of women in scientific careers.
At the University of the Free State (UFS), where I work, there is a growing institutional commitment to support emerging researchers — particularly women — through mentorship and research development initiatives. This aligns with Vision 130, which aims to foster research excellence and increase societal impact. I am fortunate to be part of the university’s Transformation of the Professoriate Mentoring Programme, designed to build a strong cohort of emerging scholars. The programme provides academic and research mentorship, supports access to networking and funding opportunities, and nurtures candidates toward assuming senior academic and research roles. It also helps lay the groundwork for future centres of research excellence.
Those of us who benefit from such opportunities carry a responsibility to extend mentorship to more women researchers, especially from underrepresented groups. Expanding women’s participation in science requires addressing the barriers that continue to limit progress. Key interventions include expanding mentorship and networking opportunities, increasing financial support and scholarships for women in STEM, and promoting national policies that support work–life balance and the needs of working mothers.
There is also an urgent need to raise awareness about women’s contributions to science and challenge persistent stereotypes that discourage girls from pursuing scientific careers. Building inclusive, diverse work environments where women feel valued and supported is essential to increasing both participation and retention. Progressive policies that promote the employment of Black women academics in STEM leadership roles are also critical. A diverse cohort of women in authority can provide gender-sensitive mentorship and create pathways for future scholars.
Pursuing a career in science demands hard work, resilience, and a commitment to continuous learning. It is a challenging journey, but deeply rewarding for those passionate about contributing to the advancement of humanity through research. It requires uncovering new insights, developing innovative solutions, and sharing knowledge that can transform lives. Marie Curie captured this spirit beautifully when she said, “I am among those who think that science has great beauty… like a fairy tale.” This sense of wonder should fuel every aspiring researcher.
Science is also fundamentally collaborative. Seek mentors, build networks, remain humble, and embrace learning from others. Your contributions — even those that seem small — form part of a larger scientific story that future generations will build on. If you are driven by curiosity, purpose, and a desire to contribute to the greater good, a career in science may be the path for you…
