In a rapidly changing, uncertain and complex world, the role that universities are playing as the engines of social mobility, as drivers of the economy and as generators of new ideas, is now more critical than ever.  Due to the universal nature of knowledge, universities are global in scope – a space that encourages new ideas, controversy, inquiry, and argument and challenges orthodox views, but they are also deeply entrenched in their local environment, influenced by socio-economic and political dynamics.  There is an expectation that universities should exhibit great levels of responsiveness and public accountability, with higher levels of trust in higher education, and between higher education and government, and higher education and the public.  The challenge for both higher education and government is to allow institutional autonomy without oppressive accountability.  

Over the past few years, the purpose of universities has been challenged in relation to their role in society, their advocacy for speaking truth to power, their continuous strive to be great universities without being elitist, and their ability to function in an age of populism. The Trump administration and, more recently, Brexit have demonstrated that there is a decline in the respect for evidence and advice from subject-specific experts.  It seems (as in the case of the Trump administration) as if empirical reality does not matter, nor does empirical reasoning form the basis of public policy – a political place that is becoming increasingly anti-intellectual.  Emotion and personal belief have been shown to carry more weight than objective facts and evidence in terms of influencing public opinion.  Fake news and ‘the alternative truth’ have also challenged the fundamental principles of a university – academic freedom and the generation of new knowledge in the pursuit of truth.

A digitally unequal society
The COVID-19 pandemic has shown deep fault lines in our society – stark poverty and inequality – that universities should engage with (and they do); however, they cannot eliminate it on their own, but can be part of the solution.  South Africa is the most unequal society in the world.  Before the COVID-19 pandemic, the South African economy was already in deep trouble, with sovereign downgrades by all the rating agencies and with an unemployment rate close to 30%.   The national lockdown, in an attempt to ‘flatten the infection curve’ and hence manage the response of the national health system to COVID-19 cases, has added to the pressure on the economy.  It is envisaged that a large number of people (estimated between 3 and 7 million South Africans) will lose their jobs after the national lockdown period, adding to poverty and an already high unemployment rate.  Even during the lockdown period, there are many South Africans living in crowded spaces, hence finding it difficult to practise social distancing, may not have running water and proper sanitation, and possibly do not have regular access to food.  

As schools and the post-school education and training sectors move online with their learning, it further shows how digitally unequal our society really is – access to connectivity, data, and an appropriate digital device is a challenge, and electricity is not evenly distributed or is non-existent in our society.  These institutions, within the environment of digital inequality, are ensuring that digital equity is maintained as far as possible.  Many churches, business leaders, and certain politicians have called for a different social pact between business, labour, and government to address the state of the economy – any such action, however, must be supplemented by concrete measures for social reform.

Regaining trust in universities
But perhaps this pandemic has also created an opportunity for science and evidence to regain credibility in informing government decisions and public trust, and for universities to demonstrate respect for evidence. During the initial stages (early March) of COVID-19 in South Africa, the epidemiologists and virologists have shown through confirmed data from the National Institute of Communicable Diseases (NICD) that South Africa was in the early phase of the infection curve – also interpreted to be the relatively low-risk phase of the curve; this would be the right time to apply the principle of social distancing.  It allowed certain organisations (such as universities) to pro-actively suspend part of their activities so as to minimise the number of people in their operational environment, well before the national lockdown was announced on 26 March – a decision based on science.

Through data and proper analyses, the NICD, other scientific bodies and the Ministerial Advisory Committee on COVID-19 provided evidence-based information to government and the public, from which meaningful decisions could be taken.  The South African government has made it perfectly clear that decisions around COVID-19 will be made based on the science associated with this pandemic – a stance to be applauded.  Hence, the risk-adjusted approach of ‘opening up’ the economy through easing the lockdown measures but constantly monitoring the infection curve is an excellent example of risk management while continuously assessing the risks.

Universities, science laboratories, and pharmaceutical companies around the globe are hard at work to develop an effective vaccine for COVID-19, which is another opportunity to demonstrate how science can assist in protecting people from this terrible virus. Universities are making advances in personal protective equipment (PPE), the development of new technologies for non-ICU provision of oxygen to COVID-19 patients, more advanced methods of testing (for the virus) to reduce turnaround times, and various other scientific studies.  

This platform is giving universities a renewed impetus to use science and scientific developments to advance societal agendas such as climate change, poverty and inequality, public health and social justice (ethics of care) – and more immediate – assisting in re-building a strong South African economy.  It is an opportunity for the public and politicians to regain trust in universities, but it is also an opportunity for universities to profile their public intellectuals so that the value of science and evidence-based output is part of policy debates and informed decision-making.  However, in doing so, universities must strengthen their relationship with society at large, be inquiry-driven, and at the same time be learning and co-creating.

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
