Global Citizen Invitation Prof Thuli Madonsela 4 July 2024

The University of the Free State (UFS) and the South African Chamber of Commerce United Kingdom (SACC UK) are pleased to present a Global Citizen Series conversation, South Africa’s Future in Focus: the post-election impact on social justice, service delivery, higher education, and the economy, from the perspective of Prof Thuli Madonsela, Director of the Centre for Social Justice in the Faculty of Law at Stellenbosch University and Professor of Law in the Law Trust Research Chair in Social Justice Studies.

As part of the Global Citizen Webinar Series, Prof Madonsela – a member of the International Anticorruption Advisory Council and Global Justice Leaders – will join UFS Vice-Chancellor and Principal, Prof Francis Petersen, and SACC UK Chairperson, Sharon Constançon, for a conversation that explores what the future holds for social justice, service delivery, higher education, and the economy in South Africa.

After thirty years of democracy, South Africans once again made their mark on 29 May 2024 in one of the most pivotal elections since 1994. Join us in person during the Free State Arts Festival or online as we explore South Africa’s Future in Focus: The post-election impact on social justice, service delivery, higher education, and the economy.

Date: Thursday 4 July 2024
In-person event SA time: 18:00-20:00 SAST, Centenary Complex, UFS Bloemfontein Campus
Webinar SA time: 18:30-19:30 / UK time: 17:30-18:30

About Prof Thuli Madontsela

Prof Thuli (Thulisile) Madonsela is the Director of the Centre for Social Justice (CSJ) in the Faculty of Law at Stellenbosch University and Professor of Law in the Law Trust Research Chair in Social Justice Studies. She is the founder of the Thuma Foundation for Democracy Leadership and Literacy and a member of the African Academy of Sciences. She was recently appointed to the UN Scientific Advisory Board and as Chairperson of Cities Alliance. She is a member of the International Anticorruption Advisory Council and Global Justice Leaders.

The former Public Protector of South Africa and full-time Commissioner in the South African Law Reform Commission was one of the 11 technical experts who helped draft the South African Constitution, and is a co-architect of several constitutionally mandated laws, including the Equality Act, Employment Equity Act, and the Promotion of Administrative Justice Act. She has an extensive background in applied constitutional, social justice, and administrative law principles, mainly based on her years of public service and her investigation of improper conduct in state affairs as Public Protector. A regular sought-after keynote speaker, Prof Madonsela has written, taught, presented papers, and published on these matters and ethical leadership, good governance, and gender mainstreaming for decades.

Prof Madonsela helped draft several international human rights instruments at UN, AU, and SADC levels, as well as country reports on such matters. She currently teaches Constitutional Law, Social Justice Law, Administrative Law, and Constitutional Governance and Ethical Leadership. She holds eight honorary law doctorates, in addition to two law degrees, a Harvard Advanced Leadership Certificate, and other postgraduate qualifications.

Named one of Time’s 100 most influential people in the world in 2014, Prof Madonsela’s global recognition includes more than 70 awards, including Rotary’s Paul Harris award, the Commonwealth Lawyers Truth and Justice award, and the global ACFE’s Cressy award. Prof Madonsela is a mother of two, a philanthropist, and an avid mountaineer who has summited Mt Kilimanjaro twice under the #Trek4Mandela-#Caring4Girls anti-period poverty campaign and the Musa Plan for Social Justice, and regularly hikes for the #Action4Inclusion campaign, a quest to end student debt.

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.
