Dr Julia Mafumo believes the relationship between health-care workers and the community is important. If the health-care practitioners are competent and compassionate, morbidity and mortality could be lessened, as services will be utilised where monitoring and early diagnosis are done.

“Nursing is regarded as one of the pillar professions in the health-care system and it is important that this service is accessible. The community needs to trust the health-care system enough to make use of it,” says Dr Julia Mafumo, Lecturer in the Department of Advanced Nursing Science at the University of Venda (Univen).

She believes that the University Staff Development Programme (USDP) is not only an opportunity for personal development, but that it will equip her to contribute to making health care accessible to every person who needs it. 

Dr Mafumo was selected as one of the ten candidates in the USDP, administered by the University of the Free State Office for International Affairs. The project provides funding for clinicians in global health to achieve a PhD qualification.

Univen has a track record of developing academics who are competent to address global health challenges. In more than a decade of collaboration with the University of Virginia in the United States, these universities have successfully developed global health researchers, some of whom are internationally renowned scientists today.

“Besides networking with personnel from other institutions and learning from them, the USDP is a chance to receive mentorship from academics with a strong international leadership pedigree in global health. The personnel in the programme supported me throughout my academic journey.”

“Being nominated for the staff development programme came as a blessing to me and I am very grateful for the opportunity,” says Dr Mafumo, who shares in an interview what the USDP programme meant to her. 

How has your background shaped the life and academic path that you have chosen?

I have always dreamt of pursuing a career in which I have the chance to share knowledge and information. When the University of Venda employed me, I took it as an opportunity to do just that.

My fulfilment comes from seeing a student who is competent and who can share the acquired knowledge and skills with the community at large.

What drew you to the USDP project’s call? 

The financial support in the programme gave me the opportunity to tend to my research activities. Going to the University of Virginia in February 2020 gave me the opportunity to make friends, but also to attend data analysis and management workshops, which were helpful for my studies.

The university is well established and has many resources that we don’t have. 

Please tell us more about your research 

As a lecturer in the Department of Advanced Nursing Science, I felt that I had an obligation to ensure that health care was accessible to every person who needed it. In the rural areas where I am based, most people depend on public health services, as they are unemployed and living in poverty. Many people often die without visiting the health-care facilities, as they fear the lack of competence and negative attitudes reported in the media about the nurses. 

In my work, I am developing guidelines to facilitate professional interpersonal skills for learners, so that when they graduate, they are competent and compassionate practitioners. 

With competent and caring practitioners, communities throughout South Africa will have trust in the health-care system and make use of public health-care services, resulting in a decrease in complications and early loss of life. 

Global health is one of the critical issues for the future of the human species, especially in Africa, where both infectious and non-communicable diseases threaten development. What will your project contribute to the field?

Globally, health care is a constitutional right, and every person is entitled to it. In many developing countries such as South Africa, non-communicable diseases are now major causes of morbidity and mortality, although they can be prevented and well managed. 

The relationship between health-care workers and the community is important. If health-care practitioners are competent and compassionate, morbidity and mortality could be lessened, as services will be utilised where monitoring and early diagnosis are done.

What are your career plans for the future? How will a PhD qualification assist you in reaching these goals?

Now that I have finished my doctoral studies, I would like to develop as a researcher and publish articles. I would also like to present papers at conferences in order to share information with colleagues nationally and internationally. 

Furthermore, I have also made plans to do what I love, to share knowledge and information; presenting workshops on the guidelines I developed to facilitate professional interpersonal skills for members in the nursing profession.

What is your advice for aspiring PhD candidates?

It is possible to achieve your dreams. With discipline, a positive attitude, and the support of supervisors, you have all you need to make your dream a reality.

Research helps farmers save with irrigation

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.
