South Africa has established itself as a regional higher education hub, which has until the recent COVID-19 pandemic been hosting increasing numbers of international students. The vast majority hails from the neighbouring countries in the Southern African Development Community and includes increasing numbers of postgraduate students, specifically doctoral students. The country has become one of the global epicentres of the pandemic. We argue that while the country is grappling with combating the virus, its higher education system and stakeholders must keep focusing on the post-COVID-19 future. The way the country and its higher-education system treat international students in the present crisis may determine whether it will be able to retain its position as a regional higher education hub, and whether it will be able to be a driver for PhD capacity development in the SADC region and Africa following the pandemic.

South African higher education has promoted ethical practices that govern their engagements with international students. The Code of Ethical Practice – accepted by all South African universities, guide the university’s actions for all phases of study, including the phase where students would be required to go home and return for studies. The common obstacles influencing international student mobility to and from the country caused by the lack of cooperation by government departments, should not have been a problem in this case, as all activities are coordinated by the South African National Coronavirus Command Council (NCCC). According to South Africa’s President, Cyril Ramaphosa, “the NCCC coordinates government’s response to the coronavirus pandemic. The NCCC makes recommendations to Cabinet on measures required in terms of the national state of disaster. Cabinet makes the final decisions”. (Written response by the President to written question NW 725 by Adv. G Breytenbach dated 5 June 2020.)  

International Students in the Initial Phase of the COVID-19 Crisis
The lockdown that the country imposed in March 2020 to combat the pandemic, resulted in a large part of its international student population returning home, particularly those hailing from neighbouring countries for whom travel was easy to organise. At the time, it was anticipated that students would be able to return after a three-week lockdown of the country. Most universities expected that their international students would come back to campuses after an extended recess in April 2020. At many universities, international offices assisted international students with travel arrangements and organised for those unable to travel, mostly students from other regions of the world, to remain in university residences until campuses would reopen. International students expected to be able to return to their universities soon, resulting in many travelling light and leaving essential learning, research, and personal items behind in residences.

However, controlling the COVID-19 pandemic proved far more complicated than anticipated, and the lockdown was replaced by a risk-adjusted strategy that provides for five alert levels, of which level five has the most severe restrictions on public life. As the country progressed to level four on 1 May 2020, South African universities were permitted to resume face-to-face classes for final-year medical students. On Wednesday (13/5), directions were gazetted that “allow for the once-off travel of final-year medical students studying at a public higher education institution to travel from their homes to the university campus where they are registered for study during the period 8-31 May 2020” (GG No. 43319 of 13 May 2020). No clarity was provided on whether this would include international students; the wording was at least wide enough to allow for this. Stakeholders interpreted the regulations in different ways, but at least a limited number of international final-year medical students returned from Lesotho. 

Preparation for the Resumption of Select Face-to-Face Classes 
When the South African Minister of Higher Education and Training, Dr Blade Nzimande, charted the way forward for South African higher education during the COVID-19 pandemic, he enunciated the principle that “all students should be given a fair opportunity to complete the academic year 2020” (speech on 23 May 2020). In this political announcement, he stated that final-year students in programmes requiring clinical training (e.g. nursing, and dental sciences) would begin from 1 June 2020. He postulated that other critical groups of students, including final-year and postgraduate students who require access to laboratory equipment, should be allowed to return to the country’s campuses. He did not refer in any way to a planned exclusion of international students, and at least some universities included international students in their planning for the resumption of select face-to-face classes in June 2020. 

International Students in Basic Education
When the teaching of select grades in basic education resumed in South Africa in June 2020, students from neighbouring countries were allowed to resume their daily commutes across the South African border according to regulations gazetted on 28 May 2020 (GG No. 43364 of 28 May 2020). It appears from individual reports received from border posts that boarding school students are returning from Lesotho and Botswana.

International Students in Higher Education   
As the country moved to alert level three on 1 June 2020, some stakeholders in South Africa’s higher education system anticipated that at least international students from neighbouring low-risk countries such as Lesotho or Botswana would be allowed to return when their face-to-face classes would resume. Directions issued by the South African Department of Higher Education and Training on 8 June 2020, however, unequivocally stated that ‘international students who returned to their home countries during the lockdown will only be permitted to return to campuses when Level 1 of the strategy is announced’ and explained, without elaborating on detail, that ‘these international students will be supported through remote learning until they return. Tailored catch-up plans will be implemented when they return.’ Consequently, many international students are likely to return after face-to-face classes in their modules have recommenced, and it is left to individual higher-education institutions to ensure that they are not ‘left behind’. Core challenges to ensure this include the cost of data in the main source countries of international students, as well as limited internet speed. Some universities are trying to alleviate this by providing data allowances for international students; however, this is not yet practised uniformly throughout the sector. 

Core Challenges 
To avoid harm to South Africa’s reputation as a preferred destination for international students, the country and its higher-education system will have to find satisfactory answers to critical questions:

• How can the South African higher-education system ensure that no international student is left behind in modules for which face-to-face classes resume, especially considering those who require clinical/laboratory training? A recent webinar between Vice-Chancellors from six SADC countries highlighted the fact that connectivity and data availability throughout Southern Africa is still one of the biggest challenges facing all higher-education systems. Not only the South African system, but all other SADC universities will have to be innovative to resolve this problem, especially where all have committed themselves to not leave any students behind.

• Who will bear the considerable cost for necessary interventions, such as the provision of data to international students abroad?

• How can the training of critical professions for combating COVID-19 in Southern Africa be sustained at South African higher-education institutions when degrees such as medicine (MB ChB degree) require clinical training and examinations through a practical component?

• How can reputational damage to South Africa as a destination for international students be avoided when, apparently, high school students from (at least) Lesotho are allowed to enter the country and return to boarding schools, but students in critical health science degrees are not allowed to return to classes?

Way forward
We posit that careful balancing of the often conflicting priorities of combating COVID-19, ensuring that no international students are left behind, and sustaining the training of professionals who are critical in the fight against COVID-19 in Southern Africa, is necessary to ensure that South Africa contributes optimally to the fight against the pandemic in Southern Africa and sustains its position as a preferred destination for international students post-COVID-19. It will be important to demonstrate to the world that the country is living up to its world-renowned Constitution, which entrenches equality as a fundamental right. Any differentiation between international and local students, as well as between secondary and tertiary education students, which does not have a rational connection to a legitimate government purpose such as protecting public health, may infringe the country’s internationally celebrated Constitution, taint South Africa’s standing as a higher education hub, and jeopardise its existing reputation as a preferred destination for international students. Moving forward, thoughtful action is required to ensure that future generations of international students choose to study in South Africa following the pandemic, and to encourage those who left in haste when the COVID-19 crisis intensified, to return to complete their studies.

Mushrooms have so many medicinal applications that humans have a substance in hand to promote long healthy lives. And it is not only humans who benefit from these macrofungi growing mostly in dark spaces.

“The substrate applied for growing the mushrooms can be used as animal fodder. Keeping all the medicinal values intact, these are transferred to feed goats as a supplement to their daily diet,” said Prof Bennie Viljoen, researcher in the Department of Microbial, Biochemical and Food Biotechnology at the UFS.

Curiosity and a humble start
“The entire mushroom project started two years ago as a sideline of curiosity to grow edible gourmet mushrooms for my own consumption. I was also intrigued by a friend who ate these mushrooms in their dried form to support his immune system, claiming he never gets sick. The sideline quickly changed when we discovered the interesting world of mushrooms and postgraduate students became involved.

“Since these humble beginnings we have rapidly expanded with the financial help of the Technology Transfer Office to a small enterprise with zero waste,” said Prof Viljoen. The research group also has many collaborators in the industry with full support from a nutraceutical company, an animal feed company and a mushroom growers’ association.

Prof Viljoen and his team’s mushroom research has various aspects.

Growing the tastiest edible mushrooms possible
“We are growing gourmet mushrooms on agricultural waste under controlled environmental conditions to achieve the tastiest edible mushrooms possible. This group of mushrooms is comprised of the King, Pink, Golden, Grey, Blue and Brown Oysters. Other than the research results we have obtained, this part is mainly governed by the postgraduate students running it as a business with the intention to share in the profit from excess mushrooms because they lack research bursaries. The mushrooms are sold to restaurants and food markets at weekends,” said Prof Viljoen.

Natural alternative for the treatment of various ailments
“The second entity of research encompasses the growth and application of medicinal mushrooms. Throughout history, mushrooms have been used as a natural alternative for the treatment of various ailments. Nowadays, macrofungi are known to be a source of bioactive compounds of medicinal value. These include prevention or alleviation of heart disease, inhibition of platelet aggregation, reduction of blood glucose levels, reduction of blood cholesterol and the prevention or alleviation of infections caused by bacterial, viral, fungal and parasitic pathogens. All of these properties can be enjoyed by capsulation of liquid concentrates or dried powdered mushrooms, as we recently confirmed by trial efforts which are defined as mushroom nutriceuticals,” he said.

Their research focuses on six different medicinal genera, each with specific medicinal attributes:
1.    Maitake: the most dominant property exhibited by this specific mushroom is the reduction of blood pressure as well as cholesterol. Other medicinal properties include anticancer, antidiabetic and immunomodulating while it may also improve the health of HIV patients.
2.    The Turkey Tail mushroom is known for its activity against various tumours and viruses as well as its antioxidant properties.
3.    Shiitake mushrooms have antioxidant properties and are capable of lowering blood serum cholesterol (BSC). The mushroom produces a water-soluble polysaccharide, lentinan, considered to be responsible for anticancer, antimicrobial and antitumour properties.
4.    The Grey Oyster mushroom has medicinal properties such as anticholesterol, antidiabetic, antimicrobial, antioxidant, antitumour and immunomodulatory properties.
5.    Recently there has been an increased interest in the Lion’s Mane mushroom which contains nerve growth factors (NGF) and may be applied as a possible treatment of Alzheimer’s disease as this compound seems to have the ability to re-grow and rebuild myelin by stimulating neurons.
6.    Reishi mushrooms are considered to be the mushrooms with the most medicinal properties due to their enhancing health effects such as treatment of cancer, as well as increasing longevity, resistance and recovery from diseases.

Valuable entity for the agricultural sector
Another research focus is the bio-mushroom application phenome, to break down trees growing as encroaching plants. This research is potentially very valuable for the agricultural sector in the areas where Acacia is an encroaching problem. With this process, waste products are upgraded to a usable state. “It is therefore, possible to convert woody biomass with a low digestibility and limited availability of nutrients into high-quality animal fodder. By carefully selecting the right combination of fungus species to ferment agro-wastes, a whole host of advantages could become inherently part of the substrate. Mushrooms could become a biotechnological tool used to ‘inject’ the substrate that will be fed to animals with nutrition and/or medicine as the need and situation dictates,” said Prof Viljoen.
