Prof Serges Kamga, newly appointed Dean: Faculty of Law.

The Council of the University of the Free State (UFS) approved the appointment of Prof Serges Kamga as Dean of the Faculty of Law for a five-year term during its quarterly meeting on 25 November 2022. 

Prof Kamga is a full Professor of Law currently working at the Thabo Mbeki African School of Public and International Affairs (TMS) at the University of South Africa (UNISA).

“Prof Kamga’s excellent research reputation nationally and internationally, his extensive networks and partnerships will contribute to further raising the profile of the Faculty of Law nationally, on the continent and globally.  As an established NRF-rated researcher, he will also be able to enhance the research output of the faculty,” says Prof Francis Petersen, UFS Rector and Vice-Chancellor. 

“Prof Kamga will lead and manage the Faculty of Law in support of the UFS’ Vision 130 and the ultimate intent for the coming years to be a research-led, student-centred, and regionally engaged university that contributes to development and social justice through the production of globally competitive graduates and knowledge, and that impactfully supports societal development,” says Prof Petersen.  

Prof Kamga is co-director of the Cross-Cultural Human Rights Centre at the Free University of Amsterdam in the Netherlands. At times, he has acted as head of the Thabo Mbeki African Leadership Institute currently Thabo Mbeki School at UNISA and has had engagements at the United States Agency for International Development (USAID), the Young African Leaders Initiative, and as managing consultant at African Legal Sources at the University of Pretoria. In 2021, he received the prestigious Ali Mazrui Award for Scholarship and Research Excellence from the University of Texas at Austin in the USA.

He holds an LLD degree in Human Rights Law from the Centre for Human Rights, University of Pretoria. Prof Kamga has also worked as a researcher at the South African Institute for Advanced Constitutional, Public, Human Rights and International Law (SAIFAC). As a researcher, he has published in accredited journals and presented papers at various national and international conferences. 

“Prof Kamga’s experience in these positions, as well as his extensive knowledge and understanding of the South African and global law fraternity, places him in good standing to lead the faculty to become a formidable and impactful force nationally, on the continent, and abroad. He will also lead the faculty to exploit opportunities and deal with the challenges that the rapidly changing higher-education environment has to deal with,” says Prof Petersen.

Prof Kamga will assume duty on 1 February 2023.

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.
