She joined the initiative two years ago as part of a consortium applying for ERASMUS+ funding for the e-service learning project.

Dr Marinda Avenant, Senior Lecturer in the Centre for Environmental Management at the University of the Free State (UFS), is working with her master’s students on a project to develop strategies to reduce the volume of solid waste reaching the Mangaung Metropolitan Municipality’s already overburdened landfill sites. 

All this came about through ‘Co-Producing Knowledge on Sustainable Growth through Service-Learning Pedagogy between African and European Higher Education Institutions’ (COPAFEU) – a project focused on ensuring that graduates have the skills they need for employment and entrepreneurship, while also contributing to sustainable local development. To do this, COPAFEU is developing a new approach where students follow the enhanced service-learning (e-service learning) route, working on real-world challenges and producing free, innovative educational resources on sustainable growth.

Dr Avenant became involved in the COPAFEU initiative two years ago when she was invited to be part of a consortium of universities applying for funding for the e-service-learning project from the ERASMUS+ funding programme, an EU funding programme for projects supporting education, training, youth, and sport.

She is leading the COPAFEU project on behalf of the Centre for Environmental Management (CEM) and the UFS.


A first time

Together with Prof Olusola (Shola) Oluwayemisi Ololade, Associate Professor and Director of CEM, and other academics, Dr Avenant is developing the e-service learning component to be incorporated into the structured Master of Science programmes specialising in Environmental Management and Integrated Water Management, respectively. 

“Our postgraduate programmes in Environmental Management and Integrated Water Management are following a blended delivery approach catering to working professionals, with short contact sessions on campus before they return to their jobs.” Dr Avenant says that their curricula have never included a service-learning component due to the limited time students spend on campus as well as their work commitments.

Providing more clarity on the e-service learning concept, she explains that an entrepreneurial component is integrated into the conventional service-learning pedagogy. “As part of the project, students will collaborate closely with lecturers and community partners to co-produce knowledge and develop digital open educational resources.”
 
According to Dr Avenant, the master’s students started with the first phase of the project in January this year, working with the community partner – the Solid Waste Management section at the Mangaung Metropolitan Municipality (MMM). In this phase, they visited a waste recycling pilot project, engaging with various stakeholders, including MMM environmental officers, residents from Mandela View, and waste pickers from the South African Waste Pickers Association, to reduce the volume of solid waste reaching landfill sites. 

Following the visit, students are conducting situation analyses of different aspects of the pilot project and are developing solutions to optimise the recycling initiative. They will present their findings and recommendations to stakeholders in an online webinar in June 2025.

In the second phase of this project, students will use the experiences and knowledge acquired in the first phase to create short videos exploring how civil society can contribute to reducing solid waste. Dr Avenant states that these videos will form part of open-access short-learning courses developed by the students themselves. “The courses will be hosted on a web-based platform, contributing to the creation of several massive open online courses (MOOCs) in the project’s final phase,” she adds.

For Dr Avenant, it is important to make an impact at the local level. “I believe that this is where environmental management truly ‘happens’ and where our students can have the greatest impact. It is also the level where environmental interventions are most urgently needed in South Africa. Real sustainable solutions and growth must happen within local communities,” she comments. 

“By focusing on local actions, our students can help to bring about meaningful and practical change,” she says.


Aligning with Vision 130

Although the Centre for Environmental Management’s involvement in the COPAFEU project has a local impact, it also aligns with Vision 130’s goal of expanding the university’s influence regionally and internationally. By collaborating with a consortium of two European and eight African universities, the project strengthens professional networks and increases the UFS’ global presence.

Just as these partnerships create opportunities for knowledge exchange and capacity building, they also provide a valuable platform for students to gain real-world experience and broaden their perspectives. Dr Avenant’s dream for her students is to see them grow into well-rounded environmental and water managers who can think critically, work across disciplines, and address complex real-world problems with innovative solutions. She hopes that this service-learning component will not only shift their perspectives, but also help them develop a diverse skill set, create a sense of social responsibility, and apply their knowledge in meaningful ways – whether by solving immediate environmental challenges or contributing to an open-access short learning course.

Beyond technical expertise, she believes that perseverance, accountability, resilience, teamwork, and ethical decision-making are just as important, and she is confident that this experience will help to establish these qualities in her students.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
