Dr Tafadzwa Clementine Maramura is a Senior Lecturer and NRF-Rated Researcher in the Department of Public Administration and Management at the UFS.

With roughly half the world’s population experiencing severe water scarcity for at least part of the year, according to the UN World Water Development Report 2024, a researcher from the University of the Free State (UFS) seeks to understand how South Africa and the rest of the African continent can ensure that every person has access to water.

Besides Dr Tafadzwa Clementine Maramura, Senior Lecturer and NRF-Rated Researcher in the Department of Public Administration and Management at the UFS, research focusing on service delivery, especially delivery of water to the most vulnerable and poorest households, her work also focuses on the water-health nexus. In February she was appointed the Secretary for the Institutional Governance and Regulations Framework – a sub-specialist group for the International Water Association (IWA), becoming the first black African female to be appointed to this position.

According to statistics quoted by Greenpeace, 5.52 billion people out of a population of 7.78 billion in 186 countries face water insecurity, of which, 1.34 billion are Africans, accounting for more than 90% of the continent’s population. The United Nations World Water Development Report 2024: water for prosperity and peace; facts, figures, and action examples state that as of 2022, 2.2 billion people were without access to safely managed drinking water.

 

Research focus

With this, and with the Sustainable Development Goals (SDGs) – especially Goal 6 (clean water and sanitation) – in mind, Dr Maramura seeks to understand how South Africa and the rest of Africa can ensure that everyone gets access to this particular resource. “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. 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.

“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,” says Dr Maramura.

She is also investigating what the government is doing to ensure it delivers on this service it is mandated to, as South Africa has all the policies in place, and the best constitution in the world, but still the poor and most vulnerable communities do not have water.

“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.”

 

The water-health nexus

Dr Maramura has book chapters coming out in June this year that focus on the water-health nexus in failed states, thereby merging SDG 3 and 6 on health and water respectively. Water plays an indispensable role in the world as it is important for accomplishing several other SDGs, such as zero hunger, poverty eradication, good health and well-being, and affordable and clean energy. It all depends on the achievement of goal 6.

Says Dr Maramura: “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.

“SDG 3 speaks to health and SDG 6 speaks to water and that is where the nexus is, nexus meaning connection between water and health. 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?”

South Africa is an upper-middle-income country but still struggles to deliver potable water to everyone and many communities in the country still rely on ventilated pit latrines due to limited access to modern sanitation facilities. With the deadline for achieving the 17 SDGs only five years away, South Africa is at risk of failing to achieve the SDGs.

 

Solving the water problems

According to Dr Maramura, there is no magic wand that can be used to solve all the country's water problems, but a collaborative and comprehensive effort is needed. “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.

“The community needs to understand, participate, and be aware of how much damage we can do by just drilling boreholes and digging wells. The private sector needs 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.”

From the government side, she says, the policies are there so 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.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
