College of Agriculture, Engineering
and Science (CAES)


Staff and students within the College of Agriculture, Engineering and Science have been busy during the time of lockdown contributing towards the fight against COVID-19. Read about some of the research being undertaken, initiatives that have been introduced and opinions expressed.


“Congratulations to the men and women of CAES for standing up to the values and principles of the University of KwaZulu-Natal.”

The culture of linking our research to community engagement is not new in the College of Agriculture, Engineering and Science. When the COVID-19 pandemic forced the university and the nation to join the world to comply with the lockdown regulations of the country, we agreed to continue our good work under protected and safe environments. We agreed to join the efforts of our government as well as national and international organisations. Our staff invested time, existing knowledge and skills to establish new grounds for long-term collaborations with partners in research and social transformation. These efforts will be part of our big plan to turn the challenges of COVID-19 into opportunities. Congratulations to the men and women of CAES for standing up to the values and principles of the University of KwaZulu-Natal.

CAES academics have been at the forefront of research being conducted in South Africa into the spread of COVID-19 and mitigation strategies to contain the spread of the disease.  Read about their findings.


A number of initiatives have been put in place by College staff and students to help the university community cope with the unusual circumstances brought about by the COVID-19 pandemic.  Read about their interventions here.

UKZN Pro Vice-Chancellor for Big Data and Informatics, Professor Francesco Petruccione, has turned to the online world so as to continue with his monthly data@breakfast seminar series during the national COVID-19 lockdown.  With the use of the online “Zoom” webinar tool, participants can tune in at 07h30 sharp to listen to top specialists from the comfort of their own homes.   To date expert sessions have been presented by COVID-19 war room members Dr Richard Lessells, Professor Tulio de Oliviera, Professor Salim Abdool Karim and Professor Mosa Moshabela.  Topics have covered local and global responses to the pandemic; the science behind South Africa’s particular response; COVID-19 genomics and epidemiology; and the national debate on smoking and COVID-19. Cybersecurity issues have also been covered by Dr Brett van Niekerk. To watch these presentations visit the Data@Breakfast page or  YouTube channel.

The CAES Student Support Services team has been hard at work and have developed a video and resources for UKZN students and staff on mental health issues during the lockdown. The video examines various overwhelming feelings which students and staff may feel during this time of uncertainty and fear.  It focuses in particular on anger, grief, depression and anxiety. The team did not have access to sophisticated studios and editing equipment as they did this from home, but have done a great job in spite of limited resources. The video unpacks each of the four commonly-experienced emotions and provides viewers with a range of possible coping strategies and skills.

UKZN’s Employee Wellness Programme for staff members and their immediate families is operational during the national COVID-19 #lockdown period. The service includes 24-hour telephonic counselling with a qualified counsellor; guidance on legal, financial, and family care matters; and trauma and manager support.  The service is available 24/7/365 to staff and their immediate families living in the same household by dialing 0800-254-255 (toll-free).  Download the ICAS On-the-Go app from the Google Play Store or the App Store. After installing this free app, open it to register. Your company code  is UKZ001.

Dr Tanja Reinhardt, Coordinator of UKZN’s Science and Technology Education Centre (STEC@UKZN) has used the time of lockdown to come up with some innovative online materials and workshops for little (and big) people stuck at home and needing some scientific stimulation.  Apart from a weekly newsletter with mathematical and science teasers and experiments aimed at young learners (find them here), Reinhardt is also offering weekly online workshops via zoom, where children can experiment with scientific principles using common household items and ingredients. Email to find out more.

With staff and student access to campus restricted by COVID-19 and online learning being the modus operandi at UKZN for the foreseeable future, the College Dean for Teaching and Learning (T&L), Professor Naven Chetty, has created a useful Teaching and Learning website to act as a point of reference and repository for relevant information. Training materials for staff and students as well as for general communication regarding Teaching and Learning in the College can be accessed here.  Staff are encouraged to routinely visit the T&L  webpage to view the available resources.

SARChI Chair in Waste and Climate Change, Professor Cristina Trois has been tasked by UKZN Vice-Chancellor Professor Nana Poku to lead a ‘GreenUKZN-COVID-19 Free’ task team post lockdown.  Their aim will be to plan and implement clean projects, waste awareness campaigns and health and safety guidelines for the safe disposal of waste on campus, when normal University activities resume.  The team will also develop guidelines to avoid the future spread of the virus in laboratories when research activities recommence.   The team’s brief is to ensure best practice waste management in times of COVID 19 on a multi-campus environment.

SAEES staff member Dr Alfred Odindo has been  working closely with Vulindlela community members to co-design safe, cost-effective and socially acceptable waste management and sanitation innovations to establish a circular economy.  The project, RUNRES: ‘The rural-urban nexus: Establishing a nutrient loop to improve city region food system resilience’ is working in Vulindlela to implement sanitation innovations to recover waste in order to strengthen the resilience of smallholder agriculture in the community. Several community workshops and focus group discussions have been conducted with the support of traditional leadership and ward councillors to define challenges and provide solutions. However, the project has had to adapt with  changing times precipitated by the COVID-19 pandemic and is using ICT tools to reach out to the community. This has proved to be immensely successful with the farmers who are able to connect seamlessly and join meetings using Zoom and WhatsApp.

A student in the School of Mathematics, Statistics and Computer Science (SMSCS), Mr Sibonelo Mhlongo, is working with his mother’s small clothing manufacturing business to arrange for the manufacture and provision of fabric masks to the University when staff and students return to campus.  Mhlongo, who is a third year student studying applied mathematics and statistics, is originally from Mtubatuba near St Lucia in northern KwaZulu-Natal. When UKZN issued a challenge to students to contribute ideas for the facilitation of continued teaching and learning under pandemic conditions, Mhlongo and his family decided to propose the manufacture of masks for UKZN, in the UKZN colours.  This initiative will not only provide much needed employment to ladies in Mtubatuba but also contributes practically to the welfare of the UKZN community.


Leading College academics have contributed to the COVID-19 debate in the press.  Read about their opinions here.


Professor Brij Maharaj from the discipline of Geography on the Howard College campus appeared in the Cape Times, Mercury and Daily Maverick on 21 April with an opinion piece arguing that COVID-19 gives us a chance to plot a new global path – and to give planet Earth a breath. Read his piece here


A group of researchers linked to UKZN’s Centre for Transformative Agricultural and Food Systems (CTAFS) and the uMngeni Resilience Project (URP) and led by Dr Tafadzwa Mabhaudhi have pointed to the fact that as the COVID-19 pandemic takes hold in South Africa a crisis within a crisis is looming. Years of apartheid have left behind a very dualistic system that serves very distinct social groups. The spread of the virus is likely to devastate further these marginalised groups who already face challenges such as poor health, low food and nutritional security, and limited access to resources and services to mitigate risk. A big part of efforts must also be focused on stemming the spread of COVID-19 itself. Crucial preventative measures will be essential to slowing the impacts of the virus, including informal food systems and smallholder producers.


Professor Suna Kassier from Dietetics and Human Nutrition at UKZN has provided some advice to maintain healthy consumption habits while dealing with added stress under the COVID-19 lockdown. Kassier explains that the uncertainty of this global pandemic can exponentially increase the daily stress most people experience. She encouraged people to be mindful about their stress coping mechanisms, which on its own, she said, is a positive step in the right direction. She advised against dipping into alcohol stockpiles and drinking more than one would under normal circumstances, saying that alcohol contributes to weight gain and a depressed mood. Kassier also advised against killing extra time by snacking absent-mindedly but rather suggested various cost-effective, healthy snack options, as well as regular meals, even small ones, to avoid the headaches, anxiety and nervousness that can result from fluctuating blood sugar levels.  In a separate opinion piece, Kassier recommended the value of laughter to lessen stress levels in the current time of uncertainty, saying that laughter was one contagion that added value to one’s life!


Postdoctoral researcher in the School of Life Sciences, Dr Yvette Ehlers Smith, presented her views in a Mail and Guardian opinion piece on how protecting nature can protect us in a time of COVID-19.  Ehlers Smith argues that as South Africa grapples with the tragic effect of the coronavirus on people, the economy and society it’s increasingly clear that our status as a megadiverse country is a blessing, but that our reliance on nature tourism is a risk. If South Africa were to establish a nature conservation philosophy that is less dependent on tourism and benefits public health, people and the economy, the advantages would be enormous in the long run. That is why it is imperative that we do everything we can now, before it’s too late, to ensure our biodiversity doesn’t become a casualty of the pandemic.
