The board of the Suid-Afrikaanse Akademie vir Wetenskap en Kuns (SAAWK) recently (22 April) announced the winners of the 2022 prizes. The academy, which was established in 1901, aims to promote the use of Afrikaans in science and the arts.

Havenga Prize for Physical Sciences

Prof Hendrik Swart, NRF B1-rated researcher, SARChI Research Chair in Solid-state Luminescent and Advanced Materials, and Senior Professor in the Department of Physics at the University of the Free State (UFS), received the prestigious Havenga Prize for Physical Sciences.

He says it is an honour to receive this award. “When I look at the list of names that have received the award in the past, I am very humbled and surprised to receive such an award.”

The Havenga Prize, for which candidates are specifically judged on research publications and evidence of their promotion of Afrikaans, has been awarded annually for the past 77 years for original research in the natural sciences or a technical field. 

A collaboration with researchers from the Nelson Mandela University (NMU) on semiconductor materials that improve the efficiency of solar cells, resulted in Prof Japie Engelbrecht (Emeritus Professor, NMU) nominating Prof Swart for this award. He is involved in an NRF collaborative research project with NMU and Linköping University in Sweden.

Prof Swart has played an important role in the acquisition of numerous research devices for analysing the thin layer of phosphor, and the semiconductor devices that can be made from such materials. His research and zeal for his work led to the establishment of the national nano-surface characterisation facility (NNSCF) containing state-of-the-art surface characterisation equipment. 

The PHI Quantes XPS system, for instance, is the first in Africa and one of only 20 in the world. The Quantes XPS system uses X-rays to determine the chemical composition of molecules on the surface of a sample. The system is unique in the sense that it also has an extra X-ray source that can determine the chemical state below the surface, which was not possible in the past. This will help to dictate the position of defects in phosphor materials, which will consequently enable the department to create better phosphor for solid-state lighting as well as solar cell applications.

The most meaningful for him, however, was the production of several well-trained postgraduate students and the generation of high-impact, well-cited scientific publications.

This award, one of several awards he has received during his career, does not signify the end of the road. On the contrary, he is looking forward to improving solar cells by using the phosphor materials they have manufactured, applying it on glass windows doped with phosphors to generate electricity.

NP van Wyk Louw Medal and Alba Bouwer Prize for children's literature

The NP van Wyk Louw Medal was awarded to Prof Hennie van Coller, a researcher who is also affiliated to the UFS. Prof Van Coller, currently an emeritus outstanding professor and research fellow at the university, was a former Head of the UFS Department of Afrikaans and Dutch, German and French, as well as Chairperson of SAAWK. He is known for his impact on the literary world, both locally and internationally, through the quality of his scientific articles and books. 

According to SAAWK, the body awards the NP van Wyk Louw Medal for a person’s creative contributions to the exploitation, organisation, and continuous development of a section of the humanities, significantly contributing to the advancement of the humanities.

Jaco Jacobs, the children’s author of more than 170 books who recently presented the 35th DF Malherbe Memorial Lecture at the UFS, was also awarded for his work. Jacobs, also a UFS alumnus, received the Alba Bouwer Prize for children's literature. The prize, which is awarded every three years, was presented to Jacobs for the book Die boekwinkel tussen die wolke, written during the COVID-19 lockdown period. 

SAAWK will present the awards later this year during two virtual award ceremonies in July.

Space-based information plays vital role in disaster-risk reduction
2017-02-28

Africa is one of the continents most affected by disasters triggered by natural hazards. The result of climate change is a reality that affects every human being, whether it is extreme heat waves, cyclones, or the devastation of drought and floods. Climate change can provoke injuries or fatalities and affects the livelihoods of people in both rural communities and urban areas. It triggers damage and losses in various sectors of development, such as housing, road infrastructure, agriculture, health, education, telecommunications, energy, and affects routine economic processes leading to economic losses.

According to Dr Dumitru Dorin Prunariu, President of the Association of Space Explorers Europe, space programmes have become an important force defining challenges of the 21st century. “Space observation is essential for climate-change monitoring,” he said.

Dr Prunariu was the keynote speaker at a two-day symposium on climate resilience and water that was hosted by the Disaster Management Training and Education Centre for Africa (DiMTEC), at the University of the Free State (UFS). He participated in the Soviet Union’s Intercosmos programme and completed an eight day-mission on board Soyuz 40 and the Salyut 6 space laboratory, where he and fellow cosmonaut Leonid Popov completed scientific experiments in the fields of astrophysics, space radiation, space technology, space medicine, and biology. He is the 103rd human being to have travelled to outer space.

The focus of Dr Prunariu’s lecture was: Space activities in support of climate change mitigation and climate resilience.

Space-based information, an extra eye that can detect a way out during disasters
“For governments to support communities affected by any disaster, precise and up-to-date information on its impacts is essential as a way to respond in a timely and effective way,” said Dr Prunariu.

Space-based information (derived using Earth observation, global navigation satellite systems, and satellite communications) can play a vital role in supporting disaster-risk reduction, response, and recovery efforts, by providing accurate and timely information to decision-makers.

“With space-based information, disaster management teams will be able to take note of recently established roads that may not appear in typical maps produced by National Geographic Institutes, but which could be used as emergency evacuation routes or as roads to deliver humanitarian assistance to those who require it in remote areas."

Space-based tools help decision-makers to improve planning
“Space-based tools and spatial data infrastructure is also crucial for policy planners and decision-makers in increasing the resilience of human settlements. Using geographic data and information collected before the occurrence of major disasters in combination with post-disaster data could yield important ideas for improved urban planning, especially in disaster-prone areas and highly-populated regions.

“In the recovery process, information on impact is used by governments to provide assistance to those affected, to plan the reconstruction process, and to restore the livelihoods of those affected,” said Dr Prunariu.

“Space observation is
essential for climate-
change monitoring.”

The symposium was attended by representatives from Liberia, Nigeria, Kenya, Ghana, Namibia, and Zimbabwe, with various international scientists from Europe imparting their expert knowledge on water and global resilience. The presence of these international experts strengthened global networks.

It isn't important in which sea or lake you observe a slick of pollution, or in the forests of which country a fire breaks out, or on which continent a hurricane arises, you are standing guard over the whole of our Earth. - Yuri Artyukhin: Soviet Russian cosmonaut and engineer who made a single flight into space.
