Dr Yolandi Schoeman
Dr Yolandi Schoeman believes the project is directly contributing to the regeneration and conservation of biodiversity, innovating towards creating unique urban biodiversity markets, and creating a thriving natural habitat that supports ecological balance and resilience.

Tim Briercliffe, Secretary General of the International Association of Horticultural Producers (AIPH), recently congratulated the City of Tshwane for the work done on urban greening and nature-based solutions that resulted in its entry: ‘Republic of South Africa City of Tshwane Pretoria East Urban Biosphere Reserve’ being selected as one of 21 finalists in the Living Green for Biodiversity category of the AIPH World Green City Awards 2024.

The list of finalists comprises the three highest-scoring entries in each of the seven categories. The Tshwane project was entered in the Living Green for Biodiversity and Urban Ecosystem Restoration category as well as the Living Green for Urban Infrastructure and Liveability category.

Dr Yolandi Schoeman, Postdoctoral Fellow/Researcher in Ecological Engineering in the centres for Mineral Biogeochemistry and Environmental Management and the Ecological Engineering Institute of Africa at the University of the Free State (UFS), played a critical role in conceptualising and driving the bio-intelligent approach that is integral to the Tshwane SA Biosphere Reserve project.

She states that being part of a project recognised as a finalist for such a prestigious global award is profoundly gratifying. “It underscores the importance and urgency of our work in ecological engineering and biodiversity conservation, validating our efforts to create resilient urban ecosystems that can inspire similar initiatives globally.”

Enhancing urban sustainability

According to her, it is one of the university’s flagship projects in Gauteng. “Our team was pivotal in developing the methodological framework that facilitated the integration of ecological, economic, social, and technological dimensions to effectively address climate change, biodiversity loss, disconnections in coupled human and natural systems, and enhance urban sustainability.”

Dr Schoeman says the project was initiated in the early stages of their investigations into sustainable urban development, with notable developments in 2023, as highlighted during the City of Tshwane Climate Change and Research Conference. She indicates that the project is continuing, with phases that include various baseline research activities, active ecosystem regeneration, continuous monitoring, roll-out of a unique biodiversity citizen science approach, integrated and inclusive stakeholder involvement, creating a unique urban biodiversity market, awareness and capacity building, and moving towards formally applying to the International Union for Conservation of Nature (IUCN) for the formal recognition of the urban biosphere region within the greater Pretoria East area.

She remarks that her inspiration to engage in this project stemmed from a commitment to address the multifaceted challenges posed by climate change and biodiversity loss, particularly in urban settings. “The most remarkable aspect of the project is its innovative approach to integrating urban development with ecological engineering, fostering a sustainable coexistence between humans and nature that serves as a model for cities worldwide,” she says.

She is excited about the impact of the work that has been done. Not only is the project directly contributing to the regeneration and conservation of biodiversity, creating a thriving natural habitat that supports ecological balance and resilience, but it is also impacting the greater Tshwane community. Dr Schoeman believes that the project significantly enhances community engagement and participation, which in turn fosters greater awareness and responsibility towards sustainable living practices.

Crafting practical, impactful solutions

Besides her instrumental role in making an impact, Dr Schoeman also enjoyed the project, particularly the opportunity to collaborate with a diverse group of stakeholders, including local communities, government bodies, and fellow researchers. “This multidisciplinary collaboration has not only enriched the project but has also been instrumental in crafting practical, impactful solutions tailored to the specific needs and characteristics of Tshwane,” she comments.

As a finalist in the Living Green for Biodiversity category of the AIPH World Green City Awards 2024, the city of Tshwane will receive a Highly Commended certificate at an awards ceremony in September in Utrecht, the Netherlands, and will ultimately have the opportunity to win the title of Grand Winner of the 2024 edition of the AIPH World Green City Awards.

Research is being done at the University of the Free State (UFS) to analyse and synthetically imitate the unique milk of various wildlife species. This research is not only of scientific value, but also serves the conservation of South Africa’s wildlife species. At the forefront of this research is Prof Garry Osthoff from the Department of Microbial, Biochemical and Food Biotechnology.

Orphaned rhino calf pulled through with surrogate milk
“There is still a lot of research to be done. Naturally the research is of scientific importance, but with surrogate milk having the same composition as the mother’s milk of a specific species, orphaned calves or cubs of that species could be pulled through during a difficult time of weaning. Bearing in mind that exotic animals fetch thousands and even millions of rands at auctions, it goes without saying a game farmer will do everything possible to provide only the best nourishment to such an orphaned animal. In such a case, synthetically-manufactured milk would be the right choice,” says Prof Osthoff.

The fruits of his research were recently demonstrated in Germany when a rhino calf was left orphaned in the Leipzig Zoo. Prof Osthoff’s article: “Milk composition of a free-ranging white rhinoceros during late lactation” was used as a directive for applying surrogate milk for horse foals (which is already commercially available), since the composition of horse and rhino milk largely corresponds. The surrogate milk was used with great success and the rhino calf is flourishing. He mentions that such an orphan is often given the wrong nourishment with the best intentions, resulting in the starvation of the animal despite the amount of cow’s milk it devours.

Milk formula for baby elephants in the pipeline
With baby elephants left orphaned due to the increase in elephant poaching for their ivory, several attempts have been made to create a milk formula in order to feed these elephants. To date, many elephants have died in captivity from side effects such as diarrhoea as a result of the surrogate formula which they were fed.

Prof Osthoff recently received a consignment of frozen milk which he, together with researchers from Zimbabwe, will use to work on a milk formula for elephants. They are studying the milk in a full lactation period of two years. During lactation, the composition of the milk changes to such an extent that a single surrogate formula will not be sufficient. Four different formulas should probably be designed.

Prof Osthoff says that of the different species he has researched, elephants are the most interesting and deviate most from the known species.

Although his research to develop surrogate milk is adding much value to the wildlife industry, and although he finds this part of his work very exciting, his research focus is on food science and nutrition. “What is currently authentic in milk research is the study of the fat globules with content, the structure and composition of the casein micelle, and the prebiotic sugars. The knowledge which is gained helps to improve the processing, development of new food products, and development of food products for health purposes,” says Prof Osthoff.
