High risk that water demand in Gauteng will exceed available resources

DrSophie-Biskop_ProfFrancois-Engelbrecht — Dr Sophie Biskop from the Department of Geography at the Schiller University Jena, Germany, and Prof Francois Engelbrecht, a Professor of Climatology at the Global Change Institute (GCI), University of the Witwatersrand, at the Southern African Mountain Conference (SAMC).

The severe El Niño drought of 2015/16, which culminated in the Vaal dam reaching an alarming low water level (~25%), prompted scientists to try and predict whether climate change could bring a drought so severe and long lasting that Gauteng could run out of water.

Prof Francois Engelbrecht, a Professor of Climatology at the Global Change Institute (GCI), University of the Witwatersrand, is one of the scientists working on this project and says though they cannot predict a Day Zero drought with certainty, he thinks it is possible that Gauteng might run out of water in the 2030s or 2040s.

“This is the biggest climate change risk South Africa faces”, he said.

Prof Engelbrecht and Dr Sophie Biskop from the Institute of Geography at the Friedrich Schiller University Jena, Germany, together with other scientists are working on a project involving hydrological modelling to predict and prevent a Day Zero from happening. Dr Biskop presented their research paper titled ‘Projected hydrological futures of South Africa's mega-dam region’ at the second Southern African Mountain Conference (SAMC2025) in March, indicating there is a high risk that the water demand in Gauteng will exceed available water resources within the Integrated Vaal River System (IVRS) under future climate change.

Gauteng may be severely compromised

The IVRS, a large, complex water system comprising water resources of different river basins, and several mega-dams within, has been constructed to secure the water supply of the Gauteng province, the economic hub in South Africa.

According to the researchers, Southern Africa is a water-stress hot spot and is projected to become significantly warmer and likely also drier under global climate change, increasing the risk of devastating hydrological droughts. The IVRS, Dr Biskop told the attendees, is vulnerable to the occurrence of multi-year droughts as experienced between 2012 and in 2016. The alarming low water level of the Vaal dam after a period of drought of 2015/16 provided early warning that water security of Gauteng may be directly and severely compromised in a changing climate. Potential evapotranspiration will increase as a consequence of strong regional warming.

Answering questions

“There is consequently a high risk that the water demand in the Gauteng province will exceed available water resources within the IVRS under future climate change. This raises the question if under ongoing climate change the natural hydrological system (without considering water transfers between dam catchments) can maintain dam levels in South Africa’s eastern mega-dam region, and particularly within the Lesotho Highlands,” explained Dr Biskop.

“To answer this question, the aim of our study is to quantify future water balance changes of several dams under changing climate conditions using the Jena Adaptable Modelling System (JAMS), a software framework for component-based development of environmental models. For this purpose, we build process-based hydrological models for several dam catchments.”

She said an ensemble of high-resolution regional climate change projections is subsequently used as forcing, to generate future hydrological projections. The analysis of projected changes in hydrological system components (precipitation, evapotranspiration, run-off) provides probabilistic estimates of the occurrence of a regional climate change tipping point - when the natural water supply can no longer achieve the full storage capacity of the mega-dams which supply the Gauteng region.

Working to prevent Day Zero

According to Prof Engelbrecht, they are working with the City of Johannesburg, the National Department of Water and Sanitation and Rand Water on this project. Their hope for this research is to create awareness in order to try and prevent Day Zero from happening. They also hope to assist these role players in building resilience and help them prepare for Day Zero. Their work with the City of Johannesburg also includes helping the city to reduce water wastage and change water users’ behaviour as well as formulating a disaster management plan should Day Zero happen.

The Southern African Mountain Conference (SAMC) series is unique as it seeks to integrate science, policy and practitioner sectors for sustainable interventions in southern African mountains. SAMC events are conceptualised by the Afromontane Research Unit (ARU) of the University of the Free State (UFS), the African Mountain Research Foundation (AMRF) and Global Mountain Safeguard Research (GLOMOS), a joint initiative between Eurac Research and the UNU Institute for Environment and Human Security. These three organisations form the Primary Partners, with the SAMC series being implemented by The Peaks Foundation (a non-profit company). SAMC2025 is being held under the patronage of UNESCO.

Alumni are the heart and soul of a university, a legacy that lives on for generations, bringing pride to the alma mater. Each year, the University of the Free State (UFS) through the Chancellor’s Distinguished Alumni Awards, celebrates its outstanding alumni, who have stood out among their peers, making waves in their careers, at home and abroad. The UFS Chancellor, Dr Khotso Mokhele, said the university plays a pivotal role in ensuring that students enjoy a life-long relationship with their alma mater. He encouraged the UFS management to create opportunities to engage students during their years of study, in order to create this mutually-beneficial relationship into the future.

The Chancellor’s Distinguished Alumnus of the Year Award, the highest honour accorded to an alumnus, recognises the distinguished national or international achievements of its recipient. The award was presented to Vian Chinner, chief executive officer at Xineoh, a performance marketing company he founded in 2014. The company, based in Bloemfontein, with offices in Cape Town, Oregon in the US, and Vancouver in Canada, specialises in applying mathematical modelling and machine learning to optimise conversion in industries including real estate, mortgage banking and e-commerce. It has generated more than $30 million in revenue for its clients.

The Young Alumnus of the Year Award acknowledges the achievements of alumni who graduated within the past decade and was presented to Leah Molatseli, founder and managing director of Lenoma Legal, who graduated with an LLB at UFS in 2010.

The Cum Laude Award is bestowed upon an alumnus in recognition of excellence in any field, whether vocational or voluntary. The awards in this category were presented to three alumni:

David Abbey, Acquisition and Leveraged Finance Deal Maker at Rand Merchant Bank. David graduated with a BCom Accounting (RU) 2007 and a BCom Hons Accounting (UFS) in 2008.

Johan Eksteen, Agricon Pelleting, graduated with an MSc in Sustainable Agriculture in 1998, and received an MBA in 2005, both at the UFS.

Zola Valashiya, Co-founder and director: Debate Afrika and Schools Projects and Campaigns Manager at Corruption Watch. He graduated with an LLB (UFS) in 2014, and Masters of Public Administration (Central European University, Hungary) in 2016. He is a Mandela Rhodes Scholar (2015) and a Young African Leadership Initiative Mandela Washington Fellow (2017) and is presently featured on the Mail & Guardian list of top 200 young South Africans.

The Executive Management Award: this service award is presented to an individual who has delivered exceptional service to the UFS and is not limited to alumni of the institution, current students and the community at large. The award was presented to Sarina Cronje, Head of Athletics at KovsieSport.

She graduated with a Bachelor of Science (UFS) in 1977 and a Postgraduate Diploma in Higher Education (UFS) in 1983. She is a mother and career woman, whose family carries the same passion and drive for sports that champions are made of.

The Kovsie Ambassador Award is bestowed upon a current student whose achievements have brought him/her distinction, benefited his/her community, and brought credit to the UFS.

Crystal-Donna Roberts graduated with a BA Drama and Theatre Arts (UFS) in 2005. She is an active television, theatre and film actress who has appeared in a multitude of theatre productions in addition to starring in Afrikaans soap opera “7de Laan, Getroud Met Rugby, Montana” and “Vallei van Sluiers” in which she won public favour. She is currently playing the lead role in the internationally acclaimed film, “Krotoa” which has won numerous awards including Best Film at the Harlem International Film Festival in New York. It also won the Award of Excellence at the International Film Festival for Women: Social Issues and Zero Discrimination, and many more.

Franco Smith, Director: Free State Rugby and Assistant Coach: Springboks. He graduated with a BA Human Movement Sciences (UFS) in 1996 and began his career in rugby in 1999 when he was selected for the Free State Under-18 Craven Week team. He became a regular on the Free State Under-20 and the UFS Shimlas teams prior to his Free State Cheetahs debut in 1992. Franco was reappointed backline coach of the Cheetahs and head coach of the Shimlas in 2015. With many accolades to his name an illustrious career in coaching and management over the years, the name Franco Smith should not be foreign to true rugby connoisseurs.

The Rector and Vice-Chancellor, Prof Francis Petersen, congratulated all the award recipients: “I applaud all alumni; you have made the city of Bloemfontein and the whole province proud.” The National Executive Alumni Chairperson, Dr Pieter du Toit, congratulated the award recipients and thanked the leadership of the university as well as the event organisers.
