The Faculty of Law at the University of the Free State (UFS) hosted the inaugural Albie Sachs Prestige Lecture on the UFS Bloemfontein Campus on 30 October 2024. The lecture – delivered by Emeritus Constitutional Court Justice Albie Sachs – was titled, ‘Who actually wrote the Constitution, and why they gave eleven unelected judges the power to strike down laws and actions of the democratically chosen parliament and president’?

In attendance at the lecture were Chief Justice of South Africa, Mandisa Maya; acting Vice-Chancellor of the UFS, Prof Anthea Rhoda; Judge of the Supreme Court of Appeal, Justice Nolwazi Mabindla-Boqwana; Senior State Advocate, Antoinette Ferreira; Project Director of the Albie Collection and Chair of the Albie Sachs Trust for Constitutionalism and the Rule of Law (ASCAROL), Vanessa September; as well as the Dean of the Faculty of Law, Prof Serges Kamga, among other high-profile guests.

In his opening address, Prof Kamga indicated that the lecture aimed to provide some responses to the core questions about the constitution and constitutionalism in South Africa. As such, Prof Rhoda echoed this sentiment, highlighting that, “when it comes to the events that preceded, surrounded, and followed the drafting and adoption of our country’s constitution, there are few commentators better placed than Judge Albie Sachs”.

The making of the constitution

As part of his lecture, Justice Sachs gave a detailed account of the making of the South African constitution. According to Justice Sachs, a total of 490 members of parliament came together to draft the constitution, which included members of the National Assembly and the Senate. These members had been mandated by 20 million South Africans who wanted a better future. As such, he described that moment as a “huge accomplishment on the part of the liberation movement”.

However, he highlighted that fulfilling this mandate was not an easy task, as it required an enormous amount of thought and mobilisation of legal technology to enable those in power at the time to surrender control of the army, police, and to some extent the economy and law-making, among other aspects. These negotiations resulted in a two-state process of constitution-making, which included the drafting of an interim constitution and the establishment of a parliament that would draft the final constitution.

Justice Sachs indicated that once the constitutional assembly sent the constitutional text to the constitutional court to ensure its compliance with agreed principles, it was found non-compliant in eleven respects, for which they had to find solutions in order for the constitution to be adopted.

As he concluded his address, Justice Sachs underscored his pride in having been involved in what he describes as a wonderfully rich story.

Forging a partnership

Subsequent to the address by Justice Sachs, the Faculty of Law and ASCAROL signed a Memorandum of Understanding (MoU), formalising the Albie Sachs Prestige Lecture as an annual event and allowing further collaboration. In fact, Prof Kamga highlighted that if Justice Sachs was not available to deliver a lecture, the trust would appoint someone in his place. To further solidify this partnership, the faculty was gifted with some of Justice Sachs’ works, including books and other materials, for its library.

Prof Rhoda expressed gratitude for this collaborative effort, saying, “We are grateful to have found such a partner in Justice Albie Sachs and the Albie Sachs Trust. May this relationship continue to blossom and bear fruit – to the benefit of our young leaders of tomorrow.”

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.
