Former Chief Justice Dikgang Moseneke

With a legal career spanning several decades, former Deputy Justice Dikgang Moseneke painted a picture of the country's legal and political landscape pre- and post-1994 during a webinar session hosted by the Faculty of Law on 7 October 2020. The webinar discussed his new book, All Rise: A Judicial Memoir. The event attracted staff, students, and members of the public who were keen to hear Moseneke – a member of the team that drafted the country’s interim constitution. 

This is his second book, covering his years on the bench, with particular focus on his 15-year term as a judge in South Africa's Constitutional Court, where he rose to the position of Deputy Chief Justice.

Justice Moseneke said his book talks about the political and legal revolution that took place in 1994 when the country moved from a common law jurisdiction to a constitutional jurisdiction. 

"When the constitution came, it made many remarkable changes, and the first of those was to superimpose the constitution on the law that existed at the time. By making the constitution supreme, the message was clear that everything else would have to fall in line with the values of the constitution, and those values were global values around freedom, democracy, equal worth of people," he said. 

He said his multi-layered book is an account of the country's political and legal transition for young people in South Africa and the rest of the continent. 

An ethical framework for the judicial function

"The first of these is just a historical account. What happened, particularly from 1994 to now. The second thing was to say what kind of transition was necessary from the common law jurisdiction to a constitutional jurisdiction, and what was the tensions that emerged, the competing claims for legitimacy; I make it quite clear that the constitution is the most important source of law that we have set in place since 1994. The third layer is telling tales of how the high courts are working, how magistrates’ courts work, how judges are appointed, how they end their service, what they are permitted to do and not to do, and therefore the ethical framework for the judicial function both at magistracy level and at the level of the high courts."

Justice Moseneke donated copies of the book to the faculty as prizes for academic excellence to senior LLB and LLM students. 

" I hope that having read and studied the themes, many people will accept that it is time for all of our excellent people to rise, to find their voice, to find their entitlement, for instance, to demand accountability, openness, good governance, democratic practice, hard work, honesty, and all those wonderful values which go together with our liberation struggle," he said.

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.
