Dr Patricks Voua Otomo
Dr Patricks Voua Otomo is the Head of the Ecotoxicology Research Laboratory and Subject Head: Zoology and Entomology in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS).

The month of June is earmarked for the celebration of National Environment Month, with the South African government and captains of industry leading the way by stimulating awareness on environmental issues and challenging everyone to become agents for change. World Environment Day, the biggest annual event of the United Nations Environment Programme (UNEP), is commemorated on 5 June, with the aim of galvanising positive environmental action. The University of the Free State (UFS) – through researchers from the Afromontane Research Unit (ARU) housed on the Qwaqwa Campus of the UFS – is playing its part in the fight against pollution, and especially water pollution in the eastern Free State.

The ARU initiated a research project in 2021, focusing on the assessment of the quality of local natural water resources in order to foster sustainable development in Phuthaditjhaba, and because of the recurring challenges pertaining to water quality and quantity in the Maluti-a-Phofung (MAP) Local Municipality. For the first such project focusing exclusively on pollution issues in a select Afromontane region – led by Dr Patricks Voua Otomo, Head of the Ecotoxicology Research Laboratory and Subject Head: Zoology and Entomology in the Faculty of Natural and Agricultural Sciences – a vibrant team of ARU scientists and students set out to determine the ecotoxicological and bacteriological state of water resources in MAP. With the permission of MAP, ARU researchers and students were allowed access to municipal wastewater treatment plants in the towns of Phuthaditjhaba and Harrismith, and ethical clearance from the UFS permitted limited environmental sampling and laboratory testing using live organisms such as snails and earthworms.

Focusing on the quality of natural water bodies
In November 2016, Ms Portia Mosolloane (2016 honours student) presented the preliminary findings of the project at an ARU colloquium held in the Golden Gate Highlands National Park. Her work has drawn attention to potential localised incidents of terrestrial contamination linked to sewage sludge management in the region. Those early findings were published internationally, and in May 2018, Ms Mosolloane went on to present her research at the 28th Annual Meeting of the Society of Environmental Toxicology and Chemistry (SETAC) in Rome, Italy.

In an attempt to mitigate sewage sludge-induced soil pollution, Ms Nomasonto Dlamini (master’s student) conducted research from 2018 on the potential beneficial effects of biochar amendment on the sewage sludge as an alternative management strategy. The results revealed that mixing biochar with sewage sludge prior to open-air storage would significantly decrease the toxic effects on terrestrial organisms such as oligochaetes. This work is still ongoing, although in May 2019, Ms Dlamini presented some of her findings at the Fifth World Congress on Risk Development and Resilience in Cape Town.

From the start, an important focus of our research has been the quality of natural water bodies in our region and its ability to support life. In 2020, Ms Mosolloane graduated cum laude with a Master of Science, having successfully established that, particularly along polluted and degraded sections of our rivers, the diversity of riparian invertebrate was heavily skewed and reduced. Her work on water quality has suggested that our failing wastewater treatment plants (due to ageing, capacity overload, and poor management) are contributing to the release of pathogenic bacteria such as Escherichia coli in the local rivers.

Mr Mbuyiselwa Moloi (a 2020 Master of Science graduate from the project) found through his research that wastewater treatment plants only contribute partially to river pollution in the region. His work, focusing on metal pollution in the Elands River (Phuthaditjhaba) and the Wilge River (Harrismith), established that although there is evidence of metal enrichment after wastewater processing by the treatment plants, some of the metal in the rivers emanates from the communities that, due to the lack of adequate refuse removal services, often dispose of their household waste directly into the rivers. Mr Moloi’s research was presented at the 2019 International Mountain Conference in Innsbruck, Austria, and was subsequently published in the International Journal of Hygiene and Environmental Health in 2020.

Ms Matseleng Semase (a 2020 Master of Science graduate from the project) worked on establishing whether the quality of the effluent released from the local wastewater treatment plants was conducive to supporting aquatic life. Using a snail species in the laboratory, she found that although of substandard quality, the effluent released from the treatment plants did not hamper growth and reproduction in her test organism. This pointed to the fact that corrective measures could still be taken to reduce the harmful impact of wastewater management processes on river health in the eastern Free State. Ms Semase’s work was presented at the 9th SETAC Africa Biennial Conference held in Cape Town in 2019, and her findings were submitted for publication in Environmental Science and Pollution Research.

First such project focusing exclusively on pollution issues
Some of our findings infused new life into the project, steering our work in unexpected directions. Early in the project we came to realise that there was a paucity of research focusing on pollution in mountain areas in South Africa and in Africa at large. Mr Hendrik Stander joined the project in 2019 as a master’s student. His task was to work on the development of fast and reliable behavioural testing protocols that could be used in the project. His preliminary findings were presented at the 40th annual meeting of SETAC North America in Toronto, Canada, and were subsequently published in the Bulletin of Environmental Contamination and Toxicology. Ms Sanele Mnkandla, who joined the project as a PhD candidate in 2020, is working on proposing water remediation strategies that could help improve the state of the rivers in the region. She recently submitted a review article on the topic for publication in Environmental Evidence. Another review article in the making and focusing on literature evidence of mountain pollution in Africa, is the brainchild of Dr Ozekeke Ogbeide, a collaborator from the University of Benin (Nigeria), who co-supervised several students and co-authored some of the scientific publications from the project.

This ongoing research, under the auspices of the ARU, is the first such project focusing exclusively on pollution issues in a select Afromontane region. With Ms Dlamini, Mr Stander, and Ms Mnkandla still actively involved in the project, we look forward to finding more answers to the environmental challenges of the eastern Free State and to working together with MAP towards environmental sustainability in the region.

Position statement: Recent reporting in newspapers
2014-10-03

 

You may have read reports in two Afrikaans newspapers, regarding recent events at the University of the Free State (UFS). Sadly, those reports are inaccurate, one-sided, exaggerated and based not on facts, but on rumour, gossip and unusually personal attacks on members of the university management.

Anyone who spends 10 minutes on our Bloemfontein Campus would wonder what the so-called ‘crisis’ is about.

We are left with no choice other than to consider legal action, as well as the intervention of the South African Press Ombudsman, among other steps, to protect the good name of the institution and the reputation of its staff. No journalist has the right to launch personal and damaging attacks on a university and its personnel, whatever his or her motives, without being fair and factual. In this respect, the newspapers have a case to answer.

But here are the facts in relation to the reports:

  1. No staff member, whether junior or senior, is ever suspended without hard evidence in hand. Such actions are rare, and when done, are preceded by careful reviews of our Human Resource Policies, labour legislation and both internal and external legal advice. Then, and only then, is a suspension affected. A suspension, moreover, does not mean you are guilty and is a precautionary action to allow for the disciplinary investigation and process to be conducted, especially where there is a serious case to answer.
  2. At no stage was the Registrar instructed to leave the university; this is patently false and yet reported as fact. We specifically responded to the media that the Registrar does outstanding work for the university and that it is our intention for him to remain as our Registrar through the end of his contract in 2016.
  3. The Rector does not make decisions by himself. Senior persons, from the position of Dean, upwards, are appointed by statutory and other senior committees of the university and finally approved by Council. No rector can override the decision of a senior committee, and this has not happened at the UFS even in cases where the Rector serves as Chair of that committee. The impression of heavy-handed management at the top insults all our committee structures, including the Institutional Forum – the widest and most inclusive of stakeholder bodies at a university – which reports directly to Council on fairness and compliance of selection processes.
  4. In the case of senior appointments, Council makes the final decision. Council fully supports the actions taken on senior appointments, including a recent senior suspension. The fact that one Council member resigns just before the end of his term, whatever the real reason for this action, does not deter from the fact that the full Council in its last sitting approved the major staffing decisions brought before it. The image therefore that the two newspapers try to create of great turmoil and distress at the university, is completely unfounded.

Even if we wanted to, the university obviously cannot provide details about staffing decisions, especially disciplinary actions in process, since the rights of individuals should be protected in terms of the Human Resource Policies and procedures of the UFS. But that does not give any newspaper the right to speculate or state as fact that which is based on rumour or gossip, or to slander senior personnel of the university. For these reasons, we have been forced to seek legal remedy and correction as a matter of urgency.

Make no mistake, underlying much of the criticism of the university has been a distress about transformation at the UFS; in particular, the perception is created that white colleagues are losing their jobs. The evidence points in the opposite direction. Our progress with equity has been slow and we lag far behind most of the former white universities; that is a fact. More than 90% of our professors are white; most of our senior appointments at professorial level and as heads of department are still overwhelmingly white. Reasonable South Africans would agree that our transformation still has a long way to go and only the mean-spirited would contend otherwise. But based on the two Afrikaans newspaper reports, an impression is left of the aggressive rooting out of white colleagues.

In the past few years the academic standard of the university has significantly improved. We now have the highest academic pass rates in years, in part because we raised the academic standards for admission four years ago. We now have the highest rate of research publications, and among the highest national publication rate of scholarly books, in the history of the UFS. We have one of the most stable financial situations of any university in South Africa, with a strong balance sheet and growing financial reserves way beyond what we had before. We now attract top professors from around the country and other parts of the world, and we have the highest number of rated researchers, through the National Research Foundation, than ever before. And after the constant turmoil of a number of years ago, we now have one of the most stable campuses in South Africa. Those are the facts.

The UFS is also regarded around the world as a university that has become a model of transformation and reconciliation in the student body. The elections of our Student Representative Council are only the most visible example of how far we have come in our leadership diversity. Not a week goes by in which other universities, nationally and abroad, do not come to Kovsies to consult with us on how they can learn from us and deepen their own transformations, especially among students.

Rather than focus on what more than one senior journalist, in reference to the article in Rapport of 21 September 2014, rightly called ‘a hatchet job’ on persons and the university, here are the objective findings of a recent survey of UFS stakeholders: 92% endorse our values; 77% agree with our transformation; 78% believe we are inclusive; and 78% applaud our overall reputation index.  Those are very different numbers from a few years ago when the institution was in crisis.

This is our commitment to all our stakeholders: we will continue our model of inclusive transformation which provides opportunities for study and for employment for all South Africans, including international students and colleagues. We remain committed to our parallel-medium instruction in which Afrikaans remains a language of instruction; we are in fact the only medical school in the country that offers dual education and training in both Afrikaans and English for our students - not only English. We provide bursaries and overseas study opportunities to all our students, irrespective of race. And our ‘future professors’ programme is richly diverse as we seek the academic stars of the future.

We are not perfect as a university management or community. Where we make mistakes, we acknowledge them and try to do better the next time round. But we remain steadfast in our goal of making the UFS a top world university in its academic ambitions and its human commitments.
