Prof Anthony Turton.

History was made in South Africa this week when a commercial laboratory became the first to extract COVID-19 RNA from various sewage samples in the country. This was done as a proof of concept, after the Dutch research agency KWR entered into an agreement with the SA Business Water Chamber on 9 April this year.

It was KWR that first demonstrated the potential of wastewater surveillance to identify the total viral load in a defined population in the Netherlands. This technology breakthrough has opened a new chapter in wastewater epidemiology on a global scale.
 
Prof Anthony Turton from the Centre for Environmental Management at the University of the Free State (UFS) says it is now possible to monitor the total viral load in each of the 824 wastewater treatment works in South Africa. Once the population size within the catchment area of the works is known, a calculation of the total viral load is possible, with a reasonable degree of accuracy. This accuracy will improve over time as the technology becomes more robust. 


Rapid deployment of technology
Prof Turton says this proof of concept is significant, because it took just eight weeks after reaching the agreement with KWR to find a laboratory with the necessary capabilities and to conduct the first tests. This is a rapid deployment of technology necessitated by the urgency of the COVID-19 pandemic. The source of funding for this demonstration was the private sector, so no taxpayer money was used. The proof of concept was deliberately designed to achieve two specific objectives. The main objective was to determine whether the Dutch methodology could be replicated in South Africa without major investment into training and procurement of laboratory equipment. The secondary objective was to understand the logistical complexities of sampling at multiple sewage works in one province, and then safely transporting those samples to the laboratory in another province. This emulates what will be needed if this methodology is adopted by government and rolled out across all provinces as required. 

Taking samples
Samples were taken over a 24-hour period using an automatic bulk sampler provided by a service provider at risk. A number of sewage works were sampled to emulate the complexity of a national operation should rapid implementation be required. The first samples were taken on Thursday 4 June. These were prepared according to a precise protocol and were shipped to the laboratory hundreds of kilometres away. The samples were prepared according to the stringent requirements of the protocol, and COVID-19 RNA was successfully extracted on Monday 8 June. Lessons learned in the first trial are being fed back to the team in preparation for the second sampling run that will take place shortly. 

Prof Turton, who serves in a facilitating role and in different capacities with each of the critical components of the overall value chain, is the man in the middle tying this whole process together. This is also a demonstration of the value of a university working in close collaboration with both government and private sector partners towards a common objective.  It is part of the Public Private Growth Initiative (PPGI), where the private sector works closely with the state to deliver core services needed to create employment opportunities as a matter of growing urgency.

Determining if the total viral load is increasing or decreasing
The second sampling run, which is about to be launched, will be a refinement of the first. Lessons learned during the logistical exercise will be applied to streamline the operation and generate an accurate costing of the service. By comparing the data for each sampling sequence, it will be possible to determine with a considerable degree of accuracy whether the total viral load in a given population is increasing or decreasing. When applied to multiple sewage works, it will be possible to identify hotspots for appropriate government intervention. This technical capability will provide robust information to both government and private sector decision-makers as they navigate their way through the complexity of a shutdown and phased re-opening of the national economy. Rapid upskilling of suitably qualified personnel will be needed, and the UFS will be playing a role in that process.

An education system based on hope is what South Africa needs – Dr Beryl Botman
2016-05-26

Description: Hope revised Tags: Hope revised

Dr Beryl Botman, a postdoctoral research
fellow at the IRSJ, with Dr Willy Nel research associate
at the IRSJ and lecturer at the UFS
Faculty of Education.

HOPE is tangible and concrete construct that should be rooted in the learning and training of teachers,” said Dr Beryl Botman, a postdoctoral research fellow at the Institute for Reconciliation and Social Justice (IRSJ).

She presented her research paper Educators, praxis, and hope: A philosophical analysis of post-apartheid teacher education policy, based on the theoretical ideologies of Paulo Freire’s Pedagogy of the Oppressed. She explores ways in which oppression has been justified, and how it has been overcome through a mutual process between the oppressor and the oppressed, drawing on Paolo Freire’s theories and practices. The presentation was held at the University of the Free State’s (UFS) Faculty of Education, on the Bloemfontein campus on 13 May 2016.

From oppression to hope

Hope should be an educational construct for teacher education in South Africa. Dr Botman asserts that epistemology and ontology should be inseparable, as they are pivotal to an education system that is transformational.

The recent country-wide student protests and demonstrations are an indicant that education institutions need to seek understanding of mechanisms that fuel social conflict. Dr Botman claims that vast social inequalities make the process of democratisation difficult thus hindering transformation. She states that a critical consciousness is important for all South Africans, but more so for educators; it can be used as a tool to understanding the mechanisms of social conflict.

“Self-reflection and self-critique is vital for educators, we need to understand that we do not have all the answers because we ever-evolving beings, working on understanding ourselves and the people around us,” said Dr Botman.

The notion of hope
“I am a farmer. I have no hope for a future that is different from today. This quotation comes from Paulo Freire’s work," said Dr Botman. She said that the South African context and environment is similar. She said that people cannot live for today; one should live for tomorrow if hope is to manifest itself.

South African education environment needs to adopt a progressive consciousness that is future orientated, “You need to be hopeful, if you are radical. You need to be able to envision a new society and a new world,” said Dr Botman.

“You cannot only denounce the present, you need to also announce your hopes for a new society. South Africa needs education systems built on understanding. Although change is difficult, it is necessary for transformation,” Dr Botman added.

What makes hope educational?
“Hope is a vision for a tomorrow that is different, and vital for a transformative education system. To get out of a state of despair, people need to educate their hope. Lately, the issue of white privilege has been brought to the fore. You need to educate your hope, so that you understand the reality of others but, more importantly, of yourself,” said Dr Botman.

Dr Botma added that teacher education needs to adopt a Freirean pedagogy with a strong philosophy based on hope. The agency of teachers can either be hopeful or without hope. It is vital that education promotes hope.

“Teachers need to rely on their existential experience, the experiences of others, and the experiences of the children or students they teach. An understanding of all these experience reinforces the idea that people are life-long learners, always learning and adapting to society’s needs,” said Dr Botman.

Teachers as agents of hope

Dr Botman stated that current South African education policy is directed towards transformation but it does not stipulate means to achieve this objective. Further, she argues that educators need to put greater emphasis on self-knowledge, self-reflection, and self-education. Connecting with teachers, parents, students and the community engages with their self-knowledge and reflection.

Reorientation of teacher education
Dr Botman concluded by mentioning that rethinking ontological and epistemological aspects of education is important, and should be a pivotal point of teacher education. A renewed vision of hope-orientated philosophy and pedagogy needs to be adopted by the education institutions. A praxis, which is an informed action, when a balance between theory and practice is achieved. There is a need for an inclusive exploration of education philosophies and education systems not only European and Western but also African and Eastern as well.
