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.

New SRC: Records of support and a victory for women

While campuses across South Africa regularly report falling voter turnout in campus elections of student representatives, the University of the Free State, in its recently completed SRC elections, registered record levels of support across our campuses with a total voter turnout of 44%. At the Bloemfontein Campus 34,4% of students voted (5052 votes) and 53,3% (1583 votes) at the Qwaqwa Campus.

Also, for the first time under the new SRC constitution, students elected a woman to lead the student body – Ms Mosa Leteane was elected as President. Another first was the election of a blind woman to the SRC – Ms Louzanne Coetzee. She will be responsible for student accessibility of our Bloemfontein SRC. This marks a victory for women in student governance.

Mr Tulasizwe Sithole was elected as the President of the SRC at our Qwaqwa Campus.

The election of Ms Leteane as President underscores the progress achieved for gender equality with near half of her SRC consisting of women (48%).

These successes are all the more significant, since this is the 4th year of elections under newly adopted SRC constitutions that allow for broader participation of diverse student constituencies in student governance.

This means that the crucial 3-year mark to test a new approach and method in governance and elections was not only successfully reached, but also in its 4th year shows the constitution as one that sustains its impact to deepen democracy and citizenship among our 30,000-strong student body.

“The results of the SRC elections across campuses show that our students are not only ready to lead our campus communities on issues relating to justice, freedom and democracy beyond our societal legacies of race and gender, but do so also for the student movement nationally. We’re immensely proud of our students, who show courage and resilience to choose leaders not for expediency, but for significance, and to lead not for some, but for all”, the Dean of Student Affairs, Rudi Buys, said.

The Qwaqwa SRC was installed on 2 September 2014, while the Bloemfontein SRC will be installed on 5 September. The Central SRC will be established on 14 September by joint sitting of the two SRCs.
