Maureen Maisiri - Keynote Speaker PhD Candidate UFS
Delivering the keynote address at the first PhD Colloquium in Disaster Risk Management and Climate Change Adaption, Maureen Maisiri said that it is important to stop taking approaches that do not include people affected by disasters and climate change.

In the midst of South Africa's complex socioeconomic challenges, including poverty, food insecurity, and environmental degradation, a study tiled: Nature-based solutions practices: implications on farm performance, sustainable environment, poverty reduction and food security among South African households? explores the potential of nature-based solutions (NBS) to address these pressing issues. Focused on disaster risk management and climate change adaptation, this study examines the adoption of NBS and its impact on environmental sustainability, agricultural productivity, and community resilience. Collins Okolie aims to offer valuable insights for policy makers, farmers, and communities by investigating the viability of NBS as a strategy for mitigating disaster risk and managing climate change. His work emphasises the importance of raising awareness about NBS and its transformative potential in enhancing farm performance, food security, and poverty reduction.

This study was one of a number of studies discussed during the first three-day PhD Colloquium in Disaster Risk Management and Climate Change Adaptation hosted by the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS).

Becoming a centre of excellence

According to Dr Olivia Kunguma, Lecturer in DiMTEC who acted as chair, the colloquium was inspired by DiMTEC’s vision to become a centre of excellence. It aimed to support PhD candidates and find solutions and recommendations for the increasing incidents and declared disasters in Africa. She added that the colloquium was also the centre’s way of contributing to the achievement of global targets, such as the Sendai Framework for Disaster Risk Reduction 2015-2030 priorities, the Paris Climate Change Agreement of 2015, and the Sustainable Development Goals.

Among the more than 80 delegates who attended the colloquium were key stakeholders in disaster management, including representatives from the National Disaster Management Centre and the Gauteng Provincial Disaster Management Centre, in addition to the PhD candidates. The event also received support from UFS research structures, including the Directorate Research Development represented by its Director, Dr Glen Taylor, and the Faculty of Natural and Agricultural Sciences, represented by the Dean, Prof Paul Oberholster. External stakeholders in attendance included Counsellor Lulama Titi-Odili, the Deputy Mayor of the Mangaung Metropolitan Municipality, and Khotso Tsotsotso, the acting Head of the Old Mutual Foundation. The event was also sponsored by the Old Mutual Foundation, the Gauteng Provincial Disaster Management Centre, and the National Disaster Management Centre. “Having the Old Mutual Foundation as the primary sponsor is exciting for the disaster management fraternity, as it will see insurance companies take a growing interest in disaster risk management, resilience building, and climate change adaptation,” said Dr Kunguma.

Dr Kunguma pointed out the excitement and productive engagement between the audience and the PhD candidates as a particular highlight of the event. She emphasised the rigorous and scientific feedback received by the candidates, allowing them to reflect on their research motivation, perspectives, and future implications. The event provided an invaluable opportunity for PhD candidates to receive practical, social, and scientific feedback from both research experts and industry professionals. Dr Kunguma remarked, “The feedback and engagements have improved their work, and sharpened their presentation skills and confidence in their work and in themselves.”

Additionally, the initiative provoked praise from the Deputy Mayor, who underlined her role in advocating for increased funding for disaster management. Counsellor Titi-Odili stressed the importance of budgeting sufficiently for disasters. She acknowledged that disasters often originate at the local level and advocated for adjustments in the disaster declaration process. She also proposed the involvement of interns or graduates in government disaster management efforts.

Jurgens Dyssel from the National Disaster Management Centre also provided his input on the value of this initiative. He indicated that such a platform brings new knowledge that should be aligned with industry needs for translation into community impact. He suggested that the colloquium be aligned with the National Disaster Management Research Agenda, a repository for all research in disaster and climate studies.

Tshepo Motlhale, Chief Director of the Gauteng Provincial Disaster Management Centre, added that the colloquium is an innovative platform for diversifying all aspects of interventions and creating a space to enhance partnerships and collaborations to come up with solutions.

Blended systematic and sustainable solutions

Giving a voice to the PhD candidates was Maureen Maisiri, who was also appointed as the keynote speaker for this event. According to her, there is a need to create blended systematic and sustainable solutions and to stop taking approaches that do not include people affected by disasters and climate change. Maisiri encouraged fellow PhD candidates to work in teams, to appreciate diversity, and to be disciplined.

In the panel discussion on My PhD journey and contribution to Disaster Risk Management and Climate Change Adaptation, the work of Daizy Nalwamba and Zukiswa Poto investigated critical aspects of disaster risk management and climate change adaptation. Nalwamba's study in Zambia explored the effectiveness of environmental education in promoting sustainable practices, revealing gaps between knowledge and practical application. Meanwhile, Poto's research in South Africa highlighted the need to prioritise economic resilience in disaster management legislation, advocating for proactive measures to support business continuity and community resilience.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
