This week on Womanity, Dr Amaleya Goneos-Malka speaks with Prof Lee-Ann Sadè Modley, from the Department of Geography, Environmental Management and Energy Studies at the University of Johannesburg. With a background spanning zoology, environmental management, sustainability, and community engagement, Prof. Modley shares her journey, shaped by perseverance, purpose, faith, her father’s soft persistence, and an unwavering commitment to creating opportunities for others. A major driving force throughout her journey was her father, who strongly believed in the transformative power of education. From her very first graduation, he continually encouraged her to pursue a doctorate, instilling in her the belief that education was not only a personal achievement but also a responsibility to uplift others in her community. Effective Solutions Require Stakeholder Buy-In One of the most pivotal moments in Prof. Modley’s career came while conducting water monitoring research in the Kaalspruit River in Tembisa. While scientists were focused on measuring pollution levels, she witnessed a resident casually throwing rubbish into the river. She realised that environmental science alone could never solve environmental problems without engaging the people living within those environments. The experience moved her from being purely laboratory and field-science focused into a more community-centred approach, where understanding human behaviour became just as important as understanding ecosystems. Prof. Modley explains how difficult this transition was for her as a “thoroughbred scientist,” but it ultimately taught her that sustainability depends on trust, participation, and community ownership. Building Trust in Communities Throughout the discussion, Prof. Modley shares insights from her work in communities such as Tembisa, Soweto, Eldorado Park, and rural Limpopo. Her projects focus heavily on water quality, water security, and environmental stewardship, but always through a collaborative lens. She highlights that, contrary to popular assumptions, communities often want to participate in environmental solutions. The challenge lies in building trust and ensuring people feel heard, respected, and included in decision-making processes. Rather than imposing solutions, her approach centres on co-creation, which includes asking communities what they believe will work best in their own environments. Communities are different. For example, in rural Limpopo, communities tend to see themselves as custodians of their water resources, protecting and preserving them collectively. In urban spaces, however, people frequently view environmental management as solely the government’s responsibility. Prof. Modley explains that one of the key challenges is helping communities reclaim a sense of ownership over their local environment. Climate Change Is Personal The conversation reinforces that climate change and environmental degradation are not distant abstract issues, they directly affect people’s homes, health, safety, and futures. Prof. Modley discusses how improper waste disposal and poor environmental practices contribute to flooding, water contamination, and worsening infrastructure problems. She advocates strongly for integrated water resource management, where everyone, from government and scientists to ordinary residents, plays a role in protecting water systems. Even small behavioural shifts, such as proper waste disposal, can collectively create meaningful environmental change. Empowering Girls Through Education and Mentorship Prof. Modley engages in several community initiatives, including the I Am Girls Programme and Eco Scouts. These initiatives aim to empower girls and young children through mentorship, environmental education, and personal development. Driven by her father’s vision of “lifting another girl up,” she invests her time in helping young women from underserved communities believe in broader possibilities for their lives. Her programmes seek to challenge cycles of poverty, substance abuse, and limited opportunities by changing mindsets and exposing girls to education, science, and leadership pathways. Making Science Accessible and Exciting Prof. Modley speaks passionately about changing perceptions around science careers, especially for girls from underrepresented communities. She notes that many learners are discouraged from pursuing science because it is viewed as difficult, inaccessible, or reserved for a select few. She actively works to make science feel exciting, relatable, and achievable by exposing learners to the university environment and demonstrating the diverse possibilities within scientific fields. Her mission is to show girls that science extends far beyond laboratories and microscopes; it can be creative, impactful, and transformative. Women Leading Sustainability Conversations As the discussion turns to gender, Prof. Modley reflects on her career experience. Interestingly, she describes how working in zoology often meant being treated equally to her male peers, which ultimately strengthened her confidence and resilience. Prof. Modley also opens up about balancing an intensive academic career with motherhood, marriage, and community engagement. She credits her strong support system, including her husband, extended family, and faith, for enabling her to pursue her ambitions while maintaining family stability. She believes women are increasingly leading sustainability conversations because of qualities such as empathy, collaboration, community-mindedness, and holistic thinking. Sustainability, she explains, is not only about ecosystems and data; it is also about people, relationships, and care. Her message to women entering the field is to be true to yourself. Women do not need to imitate men to succeed. Instead, their authentic perspectives and leadership styles are essential to building more sustainable futures. A Message of Limitless Possibility Drawing from her own experiences of being underestimated, Prof Modley encourages young women to view barriers and doubt as opportunities to prove what is possible: never allow other people’s limitations or labels to define your future.

Prof Lee-Ann Modley: Geography, Environmental Management & Energy Studies, University of Johannesburg – Limitless Possibility

In this episode of Womanity-Women in Unity, Dr. Amaleya Goneos-Malka speaks with Professor Darelle Van Greunen Director of the Centre for Community Technologies (CCT) at Nelson Mandela University, this year’s recipient of the Science Diplomacy for Africa Award. We explore how the CCT drives social development through smart, needs-driven technology in low-income communities. A Personal Journey to Purpose Professor van Greunen’s journey began in 1990, when she introduced one of South Africa’s first school computer literacy classes amid scarce resources. Her path — from teaching to leading global user experience at SAP Research — revealed the deep divide between tech creators and users, shaping her belief that technology must serve people, not the other way around. This conviction led to founding the CCT in 2014. Co-Creation and Community Impact The CCT builds solutions with communities, not for them. Needs-driven design: Teams spend time in the field listening, learning, and co-developing. Ownership and empowerment: Communities shape the design, language, and look of tools — making them “their solutions, not ours.” A powerful example is the School Health Assessment Tool, a mobile app that digitizes screenings for learners in rural Eastern Cape. It replaces paper forms, enables offline use, and has transformed care — even helping detect a child’s serious hearing issue early enough to change their learning journey. For Africa, By Africans Professor van Greunen champions the philosophy “ICT solutions for Africa, by Africans in Africa.” CCT designs tools adapted to Africa’s realities — from low connectivity to linguistic diversity. She stresses that technology designed elsewhere cannot simply be "copied and pasted" due to the continent's unique context, including intermittent connectivity, limited infrastructure, and linguistic/cultural diversity. Contextual relevance: Offline-first systems, visual and voice interfaces, and multilingual support. Respect for Behaviour: The aim is not to make people change their behavior to use a tool, but for the tool to adapt to the behaviour of the people.(part of in Africa, for Africa by Africans – design for inclusion of real people) Empowerment: Building local capacity and innovation instead of importing solutions. Opportunities for Women in Science Professor van Greunen believes it’s an exciting time for women in ICT — diversity is now seen as a strength. Yet, barriers remain: funding gaps, limited mentorship, and a weak school-to-industry pipeline. She calls for intentional ecosystems, targeted mentorship, and early confidence-building for girls in STEM. Legacy and Motivation Professor van Geunen's vision is for women to be seen not as an exception, but as an essential part of science. She hopes the next generation will lead research that transforms communities. For her, success equals impact—not titles or awards—and her desired legacy is one of hope and possibility for young women to dream and have an impact as scientists. Her final message to women is: "Don't wait for the moment. Create the moment. Don't wait for opportunity to knock on the door. You create the opportunity. Use your knowledge to make the world kinder, smarter and more just. never underestimate the power of your light as a woman” Tune in for more…

This week on Womanity-Women in Unity, Dr. Amaleya Goneos-Malka talks to Dr. Bethany Foster, who is a Professor of Paediatrics, Chair of the Department of Paediatrics at McGill University and Paediatrician-in-Chief at the McGill University Health Centre. She also serves as acting Division Director of Paediatric Nephrology. Additionally, she is Chair of The Transplantation Society’s Women in Transplantation Initiative. She shares some of the factors that contributed to choosing paediatrics and nephrology, such as how kidney disease affects the person as a whole. Her research interests extend to studying immunosuppressive medication adherence, graft outcomes in adolescent and young adult kidney transplant recipients, who tend to be at particularly high risk of graft loss. Additionally, her research addresses recipient and donor sex difference in graft outcomes. She shares that male tissues have a specific protein that is not present on female tissues, which may trigger an immune response against the graft. Prof. Foster is chair of The Transplantation Society’s Women in Transplantation Initiative (WIT), which aims “to advance and inspire women transplant professionals and champion issues of sex and gender in transplantation”. She notes that men still outcome women in transplant medicine and views WIT as an initiative to encourage more women to pursue the field. We discuss the value of mentorship and sponsorship to support women, and emphasis that women need to step up and put themselves forward for leadership roles, thus becoming role models for the women coming up behind them. In closing Prof. Foster encourages women to believe themselves, be open to constructive feedback, and continue to improve. In your career, as you develop into a self-assured individual, people should accept you as you are, and if you demand it and give them no choice they might just follow your lead. Tune in for more

This week on Womanity-Women in Unity, Dr. Amaleya Goneos-Malka talks to Prof. Kathryn Chu, who is a Professor of Global Surgery and is the Director of the Centre of Global Surgery at the University of Stellenbosch. Prof. Chu specialises in colorectal procedures and is a general surgeon. Her academic journey began at Stanford University, where she earned her undergraduate degree. Following this, she pursued her medical degree and underwent residency training in general surgery at the University of California- San Francisco. She obtained a Master's degree in Public Health and Developing Countries from the London School of Hygiene and Tropical Medicine. She currently holds positions as an adjunct professor at the University of Botswana's Department of Surgery, serves as a Board member of the Consortium of Universities for Global Health, and leads as the inaugural director of the Centre of Global Surgery. The need for surgery is time sensitive. Unfortunately, many people around the world don’t have access to surgical care when they need it. According to a 2015 report from the Lancet Commission for Global Surgery two thirds of the global population i.e. five billion people don’t have access to safe, affordable surgical care and the majority lived in low- and middle- income countries. Global surgery concerns developing health systems so that people can receive surgical care when they need it. Prof. Chu discusses some interventions to make health systems more equitable, specifically surgical access. These include policy reform, developing co-ordinated surgical plans, establishing more facilities, increasing the number of qualified personnel, upskilling people to perform specific procedures, integrating with indigenous health care practitioners. A few of Prof. Chu’s former roles include working with the health and humanitarian organisation, Medicins Sans Frontieres (Doctors without borders), who are renowned for operating in disaster and conflict zones. She also spent two years training surgeons in Rwanda, helping to rebuild their surgical training process. Through these experiences she recognised how useful surgeons are in under resourced regions. Prof. Chu has a passion for her field and highly recommends medicine for anyone that feels a calling. She shares the responsibility and privilege that doctors experience in caring for people, who are sometimes at their worst and being a critical part of people’s lives. She also encourages women to retain their femininity; empathy and care makes people better doctors and surgeons. Tune in for more.
