9 minutes to read
n this episode of Tangelic Talks, we sit down with Professor Sylvester Mpandeli, a leading voice in the Water-Energy-Food (WEF) Nexus, to unpack how these three systems are deeply intertwined—and why understanding their connections is key to building climate resilience in Southern Africa. Drawing on over two decades of research, policy engagement, and on-the-ground work, Professor Mpandeli explains the WEF Nexus in clear, accessible terms, showing how climate change is disrupting resource flows and creating compounding risks for communities. We explore practical pathways for adaptation, from integrating traditional knowledge into agricultural innovation to scaling decentralized renewable energy systems that link water access and food production.
From Limpopo to Leadership
Professor Mpandeli’s roots are in rural Limpopo Province, South Africa, where he grew up in a farming community directly impacted by water scarcity, erratic rainfall, and limited resources. Those early experiences shaped his career path, inspiring him to pursue hydrology and agricultural water management.
After years of academic study and fieldwork, he emerged as a leading voice in climate adaptation—serving on national and continental advisory panels, contributing to African Union climate resilience frameworks, and leading programs that connect research with real-world impact.
Today, he is recognized not only for his scientific expertise but for his commitment to ensuring farmers, policymakers, and local leaders can access and apply critical climate knowledge.
The Climate-Water-Food Nexus
As Professor Mpandeli explains, climate change is already here—and nowhere is this more visible than in Africa’s agricultural systems. Droughts, floods, shifting rainy seasons, and rising temperatures are putting unprecedented stress on farmers.
“If we cannot secure water, we cannot secure food. If we cannot secure food, we cannot secure livelihoods.”
In Sub-Saharan Africa, agriculture employs 60–70% of the population and contributes significantly to GDP. Yet the sector is also the most vulnerable to climate extremes.
Key pressures include:
- Increased frequency and severity of droughts
- Unpredictable rainfall patterns affecting planting seasons
- Competition for limited water resources among households, industry, and farming
- Soil degradation due to overuse and climate stress
This interconnectedness—known as the climate-water-food nexus—means solutions must be holistic, addressing not just environmental challenges but also social and economic dimensions.
Smallholder Farmers: The Frontline of Climate Change
Smallholder farmers produce the majority of Africa’s food, yet they are often excluded from decision-making processes and lack access to adaptation resources.
Professor Mpandeli stresses that these farmers are first responders to climate change impacts. However, many still farm with outdated tools, have limited irrigation options, and rely solely on rainfall.
Challenges they face include:
- Limited access to climate data and seasonal forecasts
- Financial barriers to adopting modern irrigation or drought-resistant seeds
- Weak supply chains that hinder market access for their produce
Practical Climate-Smart Agriculture Solutions
Through his work at the WRC, Professor Mpandeli champions climate-smart agriculture (CSA)—a set of practices that boost productivity, enhance resilience, and reduce emissions.
Examples of CSA in action:
- Conservation agriculture: Minimal soil disturbance, crop rotation, and organic fertilization to preserve soil health.
- Drought-resistant crops: Varieties that can survive water stress and still produce stable yields.
- Rainwater harvesting: Low-cost systems to capture and store water for irrigation.
- Efficient irrigation technologies: Drip systems that minimize water loss.
These practices are adapted to local conditions, ensuring farmers can integrate them without over-reliance on expensive imports or complex infrastructure.
Bridging Science and Community Knowledge
A recurring theme in this episode is the translation of science into actionable guidance.
“We need to speak the language of the farmers,” Professor Mpandeli emphasizes.
Scientific research often remains locked in academic journals or policy briefs. The WRC works to make data accessible—simplifying climate models, producing user-friendly tools, and training extension officers who can deliver tailored advice directly to farmers.
Policy, Cooperation, and the Regional Picture
Climate change is not confined by borders, making regional cooperation essential. Professor Mpandeli advocates for:
- Joint water resource management across shared river basins.
- Regional knowledge exchanges to share best practices.
- Coordinated investment in infrastructure that supports resilience.
He also highlights the importance of aligning adaptation strategies with economic development goals—ensuring that resilience measures create jobs, reduce poverty, and strengthen local economies.
Youth and Innovation: The Next Generation of Solutions
Professor Mpandeli is particularly passionate about engaging young people in climate adaptation.
Young entrepreneurs and scientists bring fresh perspectives, technological skills, and the drive to innovate. Empowering them with funding, mentorship, and research opportunities can accelerate progress in water and agriculture resilience.
Involving youth also ensures intergenerational continuity—passing knowledge from experienced farmers to emerging leaders who will shape Africa’s agricultural future.
Thought Provoking Q&A Session with Professor Mpandeli
I’m happy to share this with colleagues because, for me, my belief is that we need to move from theory to practice.
We can’t keep on talking and making promises—we need to deliver and ensure that we are truly assisting our people. If we take a purely linear approach, it’s going to harm us, because climate change doesn’t just affect South Africa; it also affects our neighboring countries.
If you look at Africa in general, in terms of emissions, we aren’t emitting a lot—apart from South Africa, which is the highest emitter on the continent. Yet, in terms of vulnerability, Africa is the most at risk compared to other continents. This means we have a responsibility to work with our governments and say, “We need to change the way we’re doing things.” Otherwise, one day, an entire community could be wiped out.
We must invest in early warning systems and cross-reference the impacts and challenges we face across the African continent. This means that those in North Africa need to engage with those of us further south. For example, rainfall distribution in South Africa varies from 460 to 800 millimeters per year—already below the global average. In North African countries like Egypt or Morocco, rainfall is less than 100 millimeters per year, yet they manage to feed more than a million people in each country.
So, behavior also needs to change. For example, in South Africa, non-revenue water losses—water lost through leaks or inefficiencies—are more than 35% within the value chain. That’s a huge loss.
I’m happy to share an example. If you look at the projects we are driving as an organization, the results from those projects are transferable. What does that mean? It means you can run a project in Limpopo province, and the results can also benefit communities in Gauteng or the Eastern Cape.
In other words, you can’t just demarcate research activity and say, “This only suits this particular province.” As long as your activities are aligned with the agroecological zone, you can provide solutions that work across various spatial and temporal scales. That’s our approach as an organization—and it works very well.
We’re a small organization in terms of staff numbers, but if you look at our footprint and impact, we can compete with any institution at a global level.
For us, the guiding principle is to produce more while using fewer resources. That’s our philosophy. Over and above that, we need to draw from various sources of funding—you can’t rely on just one. For example, the Water Research Commission doesn’t receive a parliamentary grant, unlike other institutions such as the Agricultural Research Council. Instead, we get a small percentage from each liter of water sold, collected on our behalf by large water utilities.
But for us, the most important thing is to ensure that our research produces results that address the socio-economic challenges we face. We need to generate outcomes that stimulate the country’s economy and create opportunities for entrepreneurs. That’s exactly what we are doing. We collaborate with organizations across the globe, and so far, we’re happy with the impact.
As I mentioned earlier, we have joint collaborations with commodity groups such as the avocado association, table grape producers, and pecan nut growers. In these partnerships, the funding is typically split 50/50 between the Water Research Commission and the commodity group.
By the end of the project, the vast majority of these groups tell us, “Sylvester, we are happy with the results.” Why? Because the work helps them earn foreign currency, export high-quality products to international markets like Europe, the Middle East, and South America, and create employment opportunities for local people.
We don’t want to conduct research just for the sake of producing knowledge that sits on a shelf. That’s why we partner with them—especially for implementation and knowledge uptake.
Collaboration also expands the range of ideas and solutions. When the private sector sees tangible, practical benefits from these projects, it sparks broader adoption. This, in turn, drives real change in the economy.
Working with the private sector also pushes us to work smarter and more efficiently. These are profit-driven organizations—they don’t delay decisions or drag their feet. And whatever they invest, they expect a strong return. If they put in 10 pounds, they want to see 1,000 pounds in value. That’s not a bad thing—it keeps everyone focused and accountable.
A few years ago, we completed projects exploring the use of solar systems for irrigation. For us, this approach is an important part of the energy mix. We can’t continue relying solely on coal for power generation—we must also look seriously at renewable energy. That’s why solar, wind, and other clean energy sources are so important.
Africa is blessed with abundant sunshine. While the intensity varies from province to province, the advantage is that renewable energy can help farmers—especially smallholder farmers—reduce dependence on expensive electricity.
That said, one of the main challenges with renewable energy infrastructure is theft and vandalism. Solar equipment in particular is often targeted. We’re addressing this by advising farmers and communities to secure their systems and by encouraging a shared sense of responsibility for protecting infrastructure.
For example, institutions that collect weather data have faced similar issues. Automatic weather stations contain SIM cards in their modems, and in the past, people have vandalized them to take the SIM cards for use in cell phones. One strategy we adopted was to install these stations at police stations or primary schools, where there is more security.
We must always stay one step ahead of criminals. But above all, raising awareness is key—people need to understand that these systems are installed to help communities grow food and adapt to the threats posed by climate change.
