From 2007 to 2014, the country experienced an exponential rise in rhino poaching – a growth of over 9,000%. Most illegal activities occur in the Kruger National Park.

 

Contributing to fight this battle is a group of five former students and colleagues from the UFS Department of Chemistry, now in the employment of Wildlife Pharmaceuticals. Situated in the Nelspruit area, Dr Inus Janse van Rensburg, Head of Research and Development; Lizette Janse van Rensburg, Head of Operations; Leo Kirsten, API expert; Dr Rikus Peens, API chemist; and Dr Chris Joubert, Laboratory Specialist, are working at this pharmaceutical manufacturing facility. The company specialises in the development, manufacturing, and end use of wildlife medicines.

 

With the medicines they develop, they are able to immobilise animals. Prof André Roodt, Discipline Head of the UFS Division of Inorganic Chemistry, who attended Indaba 9 with members of his research team in Skukuza, Kruger National Park, said wildlife species are being chemically immobilised for different reasons.

 

Prosecution of poachers

 

One example is of a rhino which was immobilised after a successful dehorning procedure by veterinarians and personnel of Wildlife Pharmaceuticals. As part of a programme to discourage poaching, selective DNA data collection is also conducted by some veterinarian groups for future use in the possible prosecution of individuals who are dealing with rhino horn. As soon as a rhino that was killed during poaching has been discovered, samples of the animal are obtained for a full analysis.

 

These samples are then stored on a database. Wherever rhino horn is confiscated (even internationally), the DNA is analysed, and the database may be consulted to see where the specific rhino was killed. The person in possession of the rhino horn may then be charged with the ‘killing’ of the original rhino.

 

Prof Roodt explained that the foundation of all medicines is based on active pharmaceutical ingredients (APIs) present in the finished pharmaceutical product, be it tablets, capsules, a syrup or a sterile injectable liquid. In accordance with local and international regulations and guidelines, chemists at API facilities are manufacturing these APIs globally.

 

Wildlife conservation

 

The APIs are respectively incorporated into registered finished pharmaceutical products, which are then used by registered veterinarians for chemical immobilisation and reversal of immobilisation in wildlife species.

 

According to Prof Roodt, the importance of developing appropriate chemical agents and the role of chemical manufacturing are crucial for animal conservation, with a scope far beyond the field of animal immobilisation, thus extending it to animal health, treatments, and vaccinations.

 

Besides saving our rhinos, wildlife species require immobilisation for different reasons. This can include, for example, wound treatment, relocation, and surgical procedures. “It is critical that the animals be immobilised to ensure limitation of stress to the animal, mitigate self-harm, allow safe handling of the animal, and for operator safety. These activities will be impossible to execute without chemical immobilisation of the animal,” said Prof Roodt.

 

Dr Janse van Rensburg, who received his PhD in the UFS Department of Chemistry in 2008, said the department, through exposing its students to, among others, complex equipment in labs as well as work in international labs to critically assess and benchmark their work against others, contributed to the success of his career at Wildlife Pharmaceuticals.

Shack study holds research and social upliftment opportunities

When Prof Basie Verster, retired head of the Department of Quantity Surveying at the University of the Free State (UFS), initiated an alternative form of housing for Johannes - one of his employees - a decision was made to base research on this initiative. This research project in Grasslands, Heidedal focused on the cost and energy efficiency of green and/or sustainable shacks.

Esti Jacobs from the Department of Quantity Surveying, together with an honours student in Quantity Surveying, a master’s student in Architecture, and young professionals at Verster Berry, helped with the project.

The physical goals of the project were to create a structure that is environmentally friendly, and maintains a comfortable interior climate in winter and summer, as well as being cost-effective to erect. The structure also had to be socially acceptable to the family and the community.

“The intention was to make a positive contribution to the community and to initiate social upliftment through this project. Structures such as the ‘green shack’ may serve as an intermediate step to future housing possibilities, since these structures are relatively primitive, but have economic value and could be marketable,” she said.

Esti explains the structure of the building, which consists of gum poles and South African pine bearers, with a timber roof and internal cement block flooring. The building is clad with corrugated iron and has a corrugated iron roof finish. Additional green elements added to the structure were internal Nutec cladding, glasswool insulation in walls, internal gypsum ceiling boards with ‘Think Pink’ insulation, internal dividing wall and door, polystyrene in the floors, and tint on the windows. A small solar panel for limited electricity use (one or two lights and electricity to charge a cellphone) and a Jojo water tank for household consumption by the inhabitants were also installed.

Esti said: “Phase one of the research has been completed. This phase consisted of an investigation into the cost of an alternative form of housing structure (comparing traditional shacks with the planned structure) as well as the construction process of the physical housing structure.

“Phase two of the research, commencing in February 2015, will last for two to three years. This phase will include the installation of temperature and relative humidity logging devices inside the existing traditional shack and the new green shack. The logs will be regularly monitored by the UFS Department of Quantity Surveying and Construction Management.

These data will enable the researchers to measure the differences in comfort levels inside the two different structures. The data, together with other information such as building materials and methods, are then processed by software programs. Through the simulation of different environments, building materials, and alternate forms of energy, software models can be used to come up with conclusions regarding more energy-friendly building materials and methods. This knowledge can be used to improve comfort levels within smaller, low-cost housing units.

The UFS will be working with Prof Jeff Ramsdell of the Appalachian State University in the USA and his team on the second phase of the project.

“This research project is ongoing and will be completed only in a few years’ time,” said Esti.

The results of the research will be published in accredited journals or at international conferences.
