07 September 2022 | Story Dr Nitha Ramnath

2022 UFS Thought-leader webinar series: What needs to be done to POWER up South Africa?

The University of the Free State is pleased to present its third webinar titled, What needs to be done to POWER up South Africa, which is part of the 2022 Thought-Leader Webinar Series. As a public higher-education institution in South Africa with a responsibility to contribute to public discourse, the University of the Free State (UFS) will be presenting the webinar in collaboration with the Free State Literature Festival. The aim of the webinar series is to discuss issues facing South Africa by engaging experts at the university and in South Africa.

Third webinar presented on 27 September 2022

South Africa’s ageing coal power plants are the cause of massive power outages on a regular basis. A dire need exists to diversify our energy mix and to consider more renewable energy. Renewable energy is regarded far cheaper than coal and the construction of coal power plants. South Africa is well positioned environmentally, with the best wind and solar potential on the entire African continent. Economic viability and benefits accompany the exploitation of renewable energy, which will provide much-needed stability in South Africa.

Date: Tuesday 27 September 2022
Time: 12:30-14:00
RSVP: https://events.ufs.ac.za/e/2022UFSThoughtLeaderWebinarSeries by 25 September 2022.

For further information, contact Alicia Pienaar at pienaaran1@ufs.ac.za.

Some of the topics discussed by leading experts in 2021 included, among others, reimagining universities for student success; corruption in South Africa – the endemic pandemic; South African politics and the local government elections; is South Africa falling apart: where to from here; predications for 2022; and why vaccinate? This year’s webinar series commenced on 31 May 2022 with the topic Crime in South Africa – who is to blame? This was followed by a webinar held in July, which asked the question, Are our glasses half full or half empty?

In her previous roles, Minyuku was the former Corporate Affairs Executive for Shell South Africa, former Chief Economic Planner for the Presidential Infrastructure Coordinating Commission (PICC), former President of the South African Planning Institute (SAPI), and former member of the SA Council for Planners (SACPLAN) appointed by the Minister of Rural Development and Land Reform.

She is currently the Board Chairperson of the South African Maritime Safety Authority (SAMSA) appointed by the Minister of Transport. Passionate about women’s participation in the energy sector, she facilitates the Unleashing Leadership Potential (ULP) Women in Energy Forum.

Steve Nicholls

Steve Nicholls is the recently appointed Head of Mitigation in South Africa’s Presidential Climate Commission. In this role, he works with a range of stakeholders to reach consensus on net-zero pathways for each sector of the economy built on a strong fact base, while supporting capacity building and cooperation within the modelling community in South Africa. Understanding future competitive economies and what kind of investments are required to enhance South Africa’s economic competitiveness while creating employment and reducing inequality and poverty will be his key focus. Nicholls maintains an ongoing advisory role to the National Business Initiative, supporting its Just Transition Pathways project.

Nicholls’ past experience is in connecting climate issues with economic impact, and therefore building the strategic case for integrating climate considerations into economic planning, strategy, risk management, investment planning, policy development and implementation.

Prior to joining the PCC, Nicholls led the Environment and Society programmes at the National Business Initiative. In this role, he ran the programmes that harnessed the collective effort of South African business across the areas of energy, climate change, and water. Nicholls has worked in the consulting industry in the United Kingdom and South Africa and has worked on projects in Europe and Southern and East Africa. He has worked across several sectors, including mining, telecommunications, government, electrical energy, oil and gas, financial services, and retail.

Happy Khambule

Khambule is the former Greenpeace Africa senior political adviser on climate and energy. He studied law at the University of Johannesburg and was recognised by the British Council as a Global Changemaker and International Climate Champion in 2008 and 2010. In 2013, he was selected as one of the Mail & Guardian 200 Young South Africans. Khambule is an official party delegate to the United Nations Framework Convention on Climate Change and negotiates various issues, such as Paris Agreement implementation and response measures. He serves on the Paris Agreement Compliance Committee and is a non-executive director in Mansa Advisory. He serves on various boards, including the Earthlife Africa board and the CleanCity SA board, as an independent non-executive board chairperson.

Khambule is part of the inaugural President's Coordinating Commission on Climate Change (PCC) and is Business Unity South Africa's Head of Environment and Energy.

Louis Lagrange

Louis Lagrange is an agricultural engineer, who is specialised in project management, food process engineering, and energy engineering. Lagrange is currently leading a team at the University of the Free State that has successfully established a new degree in Engineering Sciences. The establishment was followed by new research in energy efficiency. Lagrange is also leading the establishment of a new full Engineering degree in Agricultural and Biosystems Engineering, specialising in energy engineering, food process engineering, and environmental biosystems engineering.

Prior to joining the UFS, Lagrange spent seven years at the University of KwaZulu-Natal as Senior Lecturer in the School of Bio-resources Engineering and Environmental Hydrology. Here he focused on energy conversion through tractors, combine harvesters, and implements and developed the new food process engineering subjects.

Lagrange’s passion for education is also prevalent through the facilitation of strategic and scenario planning for groups and boards of directors, including the facilitation of certified energy manager, certified energy auditor, business efficiency professional, certified lighting efficiency professional, and fundamentals of energy management training over the past 12 years for Energy Cybernetics, the Energy Training Foundation, and currently for the Institute of Energy Professionals Africa.

Is milk really so well-known, asks UFS’s Prof. Osthoff

Prof. Garry Osthoff opened a whole new world of milk to the audience in his inaugural lecture, Milk: the well-known (?) food, in our Department of Microbial, Biochemical and Food Biotechnology of the Faculty of Natural and Agricultural Sciences.

Prof. Osthoff has done his research in protein chemistry, immuno-chemistry and enzymology at the Council for Scientific and Industrial Research (CSIR) in Pretoria and post-doctoral research at the Bowman-Grey School of Medicine, North Carolina, USA. That was instrumental in establishing food chemistry at the university.

He is involved in chemical aspects of food, with a focus on dairy science and technology. He is also involved in the research of cheese processing as well as milk evolution and concentrated on milk evolution in his lecture. Knowledge of milk from dairy animals alone does not provide all the explanations of milk as food.

Some aspects he highlighted in his lecture were that milk is the first food to be utilised by young mammals and that it is custom-designed for each species. “However, mankind is an opportunist and has found ways of easy access to food by the practice of agriculture, where plants as well as animals were employed or rather exploited,” he said.

The cow is the best-known milk producer, but environmental conditions forced man to select other animals. In spite of breeding selection, cattle seem not to have adapted to the most extreme conditions such as high altitudes with sub-freezing temperatures, deserts and marshes.

Prof. Osthoff said the consumption of the milk as an adult is not natural; neither is the consumption of milk across species. This practice of mankind may often have consequences, when signs of malnutrition or diseases are noticed. Two common problems are an allergy to milk and lactose intolerance.

Allergies are normally the result of an immune response of the consumer to the foreign proteins found in the milk. In some cases it might help to switch from one milk source to another, such as switching from cow’s milk to goat’s milk.

Prof. Osthoff said lactose intolerance – the inability of adult humans to digest lactose, the milk sugar – is natural, as adults lose that ability to digest lactose. The symptoms of the condition are stomach cramps and diarrhoea. This problem is mainly found in the warmer climates of the world. This could be an indication of early passive development of dairy technology. In these regions milk could not be stored in its fresh form, but in a fermented form, in which case the lactose was pre-digested by micro-organisms, and the human population never adapted to digesting lactose in adulthood.

According to Prof. Osthoff, it is basically the lactose in milk that has spurred dairy technology. Its fermentation has resulted in the development of yoghurts and all the cheeses that we know. In turn, the intolerance to lactose has spurred a further technological solution: lactose-free milk is currently produced by pre-digestion of lactose with enzymes.

It was realised that the milks and products from different species differed in quality aspects such as keeping properties and taste. It was also realised that the nutritional properties differed as well as their effects on health. One example is the mentioned allergy against cow’s milk proteins, which may be solved by the consumption of goat’s milk. The nutritional benefits and technological processing of milk aroused an interest in more information, and it was realised that the information gained from human milk and that of the few domesticated species do not provide a complete explanation of the properties of milk as food. Of the 250 species of milk which have been studied, only the milk of humans and a few domesticated dairy animals has been studied in detail.
