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.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
