The White-winged Flufftail, a highly endangered bird species, was spotted less than 70 km from the UFS Qwaqwa Campus, home of the Afromontane Research Unit (ARU). In collaboration with BirdLife South Africa, the ARU is conducting a study to find out if this species also made its home in the Golden Gate Highlands National Park.

This rare species has so far only been found at three sites in South Africa.


Study to benefit local community

One of the ARU’s goals is to undertake research that will benefit the local communities, including SANParks. Should it be confirmed that these rare birds are also found in the area, the status of the Golden Gate Highlands National Park in the Important Birding Area (IBA) directory is likely to increase.

Prof Aliza le Roux, Associate Professor in the Department of Zoology and Entomology on the Qwaqwa Campus of the University of the Free State (UFS) and affiliated to the ARU, is conducting the study. She is also involved in other wetland studies.

According to Prof Le Roux, it is very difficult to find the bird. In a study, Prof Le Roux, Dr Sandy-Lynn Steenhuisen (botanist in the Department of Plant Sciences), and Dr Ralph Clark (ARU Director) have been deploying song meters in a rolling grid in the wetland areas, recording all bird noises around dawn and dusk. This is a non-invasive method to record bird sounds and helps to maintain the health of wetlands.

With these song meters they are trying to create a soundscape of the wetlands, recording all the sounds of the area by changing the location of the song meters every two weeks to cover the entire 2 km-long wetland area. Soundscape ecology is a fairly new technique and could be an effective way of measuring wetland health in high-altitude settings.

“In contrast with camera traps, song meters do not need a direct line of sight to record the presence of a specific bird – it can pick up songs from 150 m away in all directions. Camera traps may, however, be useful for adding visual confirmation of any bird’s presence, which is useful for a species that has only been heard a few times. In fact, no recording of the White-winged Flufftail’s call is currently in the public domain,” says Dr Le Roux.


Collaboration with Japanese university

Using these recordings from the soundscape, the team identifies the different bird, frog, and insect sounds recorded. According to Prof Le Roux, they are fairly new to the process and she would like to learn more, specifically about the analysis of the song diversity. She is visiting researchers at the Okinawa Institute of Science and Technology (OIST) in Japan in early December to investigate the variety of tools available to effectively analyse terabytes of acoustic data. Researchers at OIST have done similar studies on soundscapes in Okinawa along an urban gradient, and their expertise as well as access to a supercomputer could boost this research significantly.

The Qwaqwa area is on the border of the White-winged Flufftail’s expected distribution range.

“Because they and their habitat are threatened,
we are not sure if they are in the area;
and whether they may only be here to breed.”

Associate Professor, UFS.


“If we find that they did make the park their home, they will be more protected, as the park is a conservation area.”

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.
