Dr Mutshidzi Mulondo, an academic in the Division of Public Health within the Faculty of Health Sciences, at the University of the Free State (UFS), has won a prestigious Global Health Award at the margins of the Global Health Summit in London, the UK.

Dr Mulondo, who is a Novartis Reimagining Healthcare Scholar and a Visiting Scholar at the Beaver College of Health Sciences at Appalachian State University, in the US, was a finalist in two categories: ‘Mental Health and Well-being’ and ‘Rising Star’. She won the Zenith Global Health Award under the category ‘Mental Health and Well-being’. The awards ceremony took place on 28 September and saw health professionals and academics gather in Europe for the auspicious occasion.

“This nomination and selection are an honour that bears testament to my dedication and commitment to SDG 3 (Good Health and Well-being). I hope this win serves as inspiration to young people, particularly to young women in academia and in the sciences,” says Dr Mulondo. The awards are an esteemed platform renowned for celebrating global recognition and excellence, fostering collaboration and innovation in the healthcare sector. They further serve as recognition for contributions made through education, research and/or technology and innovation.

Eco-anxiety

Dr Mulondo, who was invited to attend the summit for the first time, joined a panel of speakers on the session theme ‘mental health and climate change’ where she shared insights on eco-anxiety – the intersection of climate change and mental health which was coined by Albrecht as the chronic fear of environmental change.

Research by the McKinsey Health Institute, says Dr Mulondo, a fellow of the UFS Emerging Scholar Accelerator Programme (ESAP) and member of the UNESCO AG for Women in Science, indicates that more than 75% of young people are pessimistic about the future due to climate change. Most young people in the activism frontlines experience activist burn-out from consistent campaigning, while others experience eco-gaslighting from those who feel climate change is a non-issue. These negative emotions are further exacerbated by young people’s exposure to social media of constant images and conversations about environmental degradation due to climate change.

Pact for the future

Dr Mulondo flew to London from New York after participating in the 79th United Nations General Assembly’s Summit of the Future and Science Summit, as well as the New York Climate Week. She further provided insights into the adoption of the Pact for the Future which was adopted during the Summit of the Future. “With only 17% of the Sustainable Development Goals (SDGs) targets on track to be achieved by 2030, 18% stagnant and 17% regressed to pre-2015 when the goals were first adopted (SDG Report 2024), Mental Health still remains among 10 global health issues to track according to the World Health Organisation (WHO),” says Dr Mulondo.

“The Summit of the Future, which is regarded as a once-in-a-generation high-level event,” she continues, “was aimed at establishing a new global consensus to safeguard the present and future generations. Current challenges such as health pandemics, political unrest, and climatic changes were factored into discussions to keep apace with the changing world in the adoption of the Pact for the Future”.

Recommendations and mitigation efforts should focus on encouraging those experiencing eco-anxiety to focus on joining collective action efforts (i.e. campaigns to clean ocean and beach environments (etc,) so that they feel they are doing something towards saving the planet. “This will help alleviate the feelings of ‘hopelessness’ which some experience from not knowing what to do about the environmental degradation. Furthermore, intergenerational collaboration is necessary for young people to voice their concerns and innovative ideas on the issue, while the older generation listens and further shares their lived wisdom. Ultimately, collective support (Ubuntu) is what is needed as part of the mitigation efforts,” concludes Dr Mulondo.

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.
