21 June 2021 | Story Dr Patricks Voua Otomo
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.

Inaugural lecture: Prof. Annette Wilkinson
2008-04-16

A strong plea for a pursuit of “scholarship” in higher education

Prof. Annette Wilkinson of the Centre for Higher Education Studies and Development in the Faculty of the Humanities at the University of the Free State (UFS) made as strong plea for a pursuit of “scholarship” in higher education.

She said in her inaugural lecture that higher education has to deal with changes and demands that necessitate innovative approaches and creative thinking when it concerns effective teaching and learning in a challenging and demanding higher education environment. She referred to a recent research report prepared for the Council for Higher Education (CHE) which spells out the alarming situation regarding attrition rates and graduation output in South African higher education and emphasises factors leading to the situation. These factors include socio-economic conditions and shortcomings in the school and the subsequent under preparedness of a very large proportion of the current student population. However, what is regarded as one of the key factors within the sector’s control is the implementation of strategies for improving graduate output.

She said: “The CHE report expresses concern about academics’ adherence to traditional teaching practices at institutions, which have not changed significantly to make provision for the dramatic increase in diversity since the 1980s.

“Raising the profile of teaching and learning in terms of accountability, recognition and scholarship is essential for successful capacity-building,” she said. “The notion of scholarship, however, brings to the minds of many academics the burden of ‘publish or perish’. In many instances, the pressures to be research-active are draining the value put on teaching. Institutions demand that staff produce research outputs in order to qualify for any of the so-called three Rs – resources, rewards and recognition.

“These have been abundant for research, but scarce when it comes to teaching – with the status of the latter just not on the same level as that of research. From within their demanding teaching environments many lecturers just feel they do not have the time to spend on research because of heavy workloads, that their efforts are under-valued and that they have to strive on the basis of intrinsic rewards.”

She said: “It is an unfortunate situation that educational expertise, in particular on disciplinary level, is not valued, even though in most courses, as in the Programme in Higher Education Studies at the UFS, all applications, whether in assignments, projects or learning material design, are directly applied to the disciplinary context. We work in a challenging environment where the important task of preparing students for tomorrow requires advanced disciplinary together with pedagogical knowledge.”

Prof. Wilkinson argued that a pursuit of the scholarship of teaching and learning holds the potential of not only improving teaching and learning and consequently success rates of students, but also of raising the status of teaching and recognising the immense inputs of lecturers who excel in a very demanding environment. She emphasised that not all teaching staff will progress to the scholarship level or are interested in such an endeavour. She therefore suggested a model in which performance in the area of teaching and learning can be recognised, rewarded and equally valued on three distinct levels, namely the levels of excellence, expertise and scholarship. An important feature of the model is that staff in managerial, administrative and support posts can also be rewarded for their contributions on the different levels for all teaching related work.

Prof. Wilkinson also emphasised the responsibility or rather, accountability, of institutions as a whole, as well as individual staff members, in providing an environment and infrastructure where students can develop to their full potential. She said that in this environment the development of the proficiency of staff members towards the levels of excellence, expertise and scholarship must be regarded as a priority.

“If we want to improve students’ success rates the institution should not be satisfied with the involvement in professional development opportunities by a small minority, but should set it as a requirement for all teaching staff, in particular on entry into the profession and for promotion purposes. An innovative approach towards a system of continuous professional development, valued and sought after, should be considered and built into the institutional performance management system.”

As an example of what can be achieved, Prof. Wilkinson highlighted the work of one of the most successful student support programmes at the UFS, namely the Career Preparation Programme (CPP), implemented fourteen years ago, bringing opportunities to thousands of students without matric exemption. The programme is characterised by dedicated staff, a challenging resource-based approach and foundational courses addressing various forms of under preparedness. Since 1993 3 422 students gained entry into UFS degree programmes after successfully completing the CPP; since 1996 1 014 of these students obtained their degrees, 95 got their honours degrees, 18 their master’s degrees and six successfully completed their studies as medical doctors.

Prof. Wilkinson said: “I believe we have the structures and the potential to become a leading teaching-learning university and region, where excellence, expertise and scholarship are recognised, honoured and rewarded.”
