Mandela Day
The DiMTEC team marked Mandela Day by planting indigenous trees on campus, promoting sustainability and community resilience through nature-based solutions.

The University of the Free State’s (UFS) Centre for Disaster Management Training and Education Centre (DiMTEC) commemorated Nelson Mandela International Day on 18 July by planting trees that help embed nature-based solutions at the heart of disaster risk reduction and climate change adaptation.

“It’s a simple act, yet deeply symbolic – a commitment to sustainability, climate resilience, and future generations,” said Dr Tlou Raphela-Masuku, a Senior Lecturer at DiMTEC. “Nature-based solutions, such as planting indigenous trees, are not just theoretical strategies; they are practical tools to reduce disaster risk, restore ecosystems, and build community resilience.” 

One of the trees planted, the indigenous, resilient Wild Olive (Olea europaea subsp. africana), known locally as Mohlware, embodies the drive to place nature-based solutions at the forefront of disaster risk reduction. “This tree is drought-tolerant and well-adapted to Bloemfontein’s semi-arid climate,” Dr Raphela-Masuku explained. “It stabilises soil, prevents erosion, supports biodiversity, and cools urban spaces. Its thick canopy shelters birds and small mammals, while its deep roots nourish and protect the earth. In a warming world, every Wild Olive planted is a small act of resistance against climate change.” 

 

Collaborative programme

Dr Raphela-Masuku said the tree-planting programme, a collaboration with UFS Protection Services and University Estates, ties directly into the principles the centre teaches in its Master's of Disaster Management module Ecosystem-Based Disaster Risk Reduction (ECO-DRR). 

“From the viewpoint of the African Union’s Science and Technology Advisory Group, it is befitting that as part of the work dedicated to disaster risk reduction initiatives in the African continent, this day is a reminder that we promote community service, resilience and social justice in the ‘Africa we want’. Furthermore, Mandela Day activities align with the Sendai Framework for Disaster Risk Reduction (SFDRR)’s priorities of understanding risks and strengthening disaster governance at all levels,” remarked Prof Alice Ncube, an Associate Professor at DiMTEC.

She added that, “In a city like Bloemfontein, which is not exempt from drought accelerating frequently and temperatures rising yearly, choosing to plant climate-resilient, indigenous species isn’t merely wise, it’s necessary. Trees like the Wild Olive don’t just provide shade and beauty; they help cool urban environments, support biodiversity, and protect our university community from floods and storms. They represent a forward-thinking investment in a sustainable, climate-adapted future. Mandela Day reminds us that service should be continuous, not confined to a single day. A tree planted today will outlive us, offering shade, shelter, and hope to those who come after. As Mandela himself said, ‘The true meaning of life is to plant trees under whose shade you do not expect to sit.’”

 

Commitment to change

Mandela Day also fits in with the UFS’ Vision 130 strategic intent. It is a day that reminds us that everyone has the power to make a difference. In the spirit of Madiba’s legacy, we can commit to fostering social justice, human dignity, and sustainable development through academic excellence and meaningful community engagement. In the face of climate change, biodiversity loss, and environmental degradation, each seed we plant becomes an act of defiance as well as an act of hope.

Prof Samuel Adelabu, Vice-Dean: Postgraduate and Research in the Faculty of Natural and Agricultural Sciences, applauded the team’s efforts. “We are planting trees that represent sustainability, things that can stay for long. I believe we are all practising sustainability in this initiative we are doing today to show that the university, as well as the faculties, are in line with sustainability.”

The field of Nuclear Medicine in South Africa and the rest of the world are expanding rapidly due to the development of hybrid cameras and new radiopharmaceuticals. These developments have a huge impact on the diagnosis and therapy of cancer.

The most advanced of these cameras, Positron emission tomography combined with normal CTs (PETCT), are not yet widely available in South Africa due to the cost of the cameras and the radiopharmaceuticals. A more cost-effective alternative can be of great benefit. To achieve this, the focus should be on developing new radiopharmaceuticals that can be used with the current cost-effective gamma cameras, according to University of the Free State researcher, Dr Je’nine Horn-Lodewyk from the Department of Nuclear Medicine.

Fluorodeoxyglucose (18F-FDG), a radiolabelled glucose analogue, is currently the radiopharmaceutical most commonly used in PET/CT imaging for mainly oncology indications. Although it is considered the gold standard for imaging in several malignancies, it does have certain disadvantages. An 18F-FDG PET/CT diagnostic imaging study can cost between R25 000 and R35 000 for a single patient in the private sector. The 18F-FDG is also more radioactive, which requires much stricter handling and shielding to avoid high radiation dosages to staff and patients.

Successful research potential innovative solution
In the search for the ideal radiopharmaceutical for tumour detection, the South African National Nuclear Energy Corporation (Necsa) developed a local synthesis process for ethylenedicysteine-deoxyglucose (EC-DG). EC-DG is also a glucose analogue similar to FDG. They succeeded in labelling the compound with Technetium-99-metastable-pertechnetate (99mTcO4-), the most common nuclear medicine isotope used for approximately 95% of nuclear medicine procedures, creating 99mTc-EC-DG.

In partnership with Dr Horn-Lodewyk, this compound was successfully used in various animal models and clinical scenarios, resulting in approval by the Medicine Control Council to use it in a human study. Research is also planned in order to investigate diagnostic accuracy in other cancers like lymphoma.  The end result of this research can produce a radiopharmaceutical that is cost effective, does not require the use of costly specialised equipment, has no significant side-effects, no special patient preparation, renders late imaging possible, and has decreased radiation risks.

Dr Horn-Lodewyk is grateful for the support of her mentor, Prof Anton Otto, as well as Dr Gert Engelbrecht, Head of the Department of Nuclear Medicine, Prof Jan Rijn Zeevaart from North-West University’s Preclinical Drug Development Platform and Necsa, and Judith Wagener from Necsa. This innovative research would also not have been possible without the financial assistance of Dr Glen Taylor and Eleanor van der Westhuizen in the Directorate of Research Development.
