Poverty in the Thabo Mofutsanyana District (the poorest district in the Free State province) has implications for both the mountain environment and the people in the area. Pictured here is Prof Geofrey Mukwada, Associate Professor in the Department of Geography on the UFS Qwaqwa Campus, also affiliated to the Afromontane Research Unit (ARU).

Poverty, defined by Statistics South Africa as earning less than R300 a month, is a reality that many mountain communities struggle with.

Prof Geofrey Mukwada, Associate Professor in the Department of Geography on the UFS Qwaqwa Campus, also affiliated to the Afromontane Research Unit (ARU), published a number of articles on the mountain population in the Thabo Mofutsanyana District (the poorest district in the Free State province). In a research paper with postgraduate student Solomon Zondo, he specifically focuses on the value-chain analysis of the Witsieshoek conservation area and its environment. 

They looked at the inter-relationship between nature and the rural population and how the environment has changed as a result. For this largely poor community, the income generated from natural resources is an important source of livelihood. 

To earn a living, the community is pursuing several ways to generate an income. This has implications for both the mountain environment and the people in the area. 

Impacting the environment

Whether it is mining for sandstone, herding cattle or selling medicinal plants, all these activities have an ecological and socio-economic impact. 

A large percentage of the population in the Witsieshoek Community Conservation Area derives their income from livestock grazing. Cattle herding often leads to overgrazing – which results in soil erosion in the long term, preventing water from draining into the ground and depriving plants from much-needed moisture. Connected to the excessive removal of indigenous plants, is the spread of invasive species. As invasive trees and vegetation gulp up water, the severe impact of drought in the area is increasing.

Harvesting and selling medicinal plants to generate income for a sustainable livelihood also affect the surrounding environment. The mostly elderly ladies harvest and sell, among others, Arum lily and Pineapple lily for their medicinal properties and ornamental use. Harvesting these plants adds to the spread of invasive species, as they push away indigenous plants.

Small sandstone mining operations are another means to earn a living. Neither the customer, locally or outside the Witsieshoek area, nor the supplier, usually from Witsieshoek, is held accountable for the degradation of the environment. Careless mining not only results in a decline in ecosystem health, with scree from sandstone cutting littering the rangelands and the finer particles causing silt in rivers and dams (damaging any equipment used to extract water from rivers and dams); it also spoils pastures which locals depend on for their livelihood. 

Even with the 15% increase in tourism (2016), a living through the holiday industry is not always keeping the wolf from the door. According to Prof Mukwada, many literature sources have shown that tourism may fail to reduce poverty. During a study, respondents interviewed in the Clarens area indicated that they only receive wages during the busy months of the year (approximately 4–6 months). Many of the workers in Clarens and the Golden Gate Highlands National Park do not have easy access to chain stores, but only to small grocery stores where goods are much more expensive. Travelling to a town where they will pay less for groceries is costly, making it difficult to have the same standard of living as workers elsewhere.

“With the current situation, water insecurity is likely to worsen,” says Prof Mukwada.

Coming up with solutions

Is it possible to look for alternative livelihood sources? It is not easy to come up with simple solutions to the challenges. As Prof Mukwada explained, what might be a solution to one problem could have negative implications on another front. “One needs an integrated approach,” he says. 

In terms of tourism, one could consider training the locals in tourism-related skills, adequately equipping them with skills to increase their value. “Develop tourism that is inclusive and will benefit low-income earners who cannot invest in hotels and restaurants,” Prof Mukwada adds. 

And with a large number of people earning their income from herding, one can suggest that nearby, flatter land is made available to resettle communities, thus providing an alternative area for grazing. In flatter areas there is also less erosion. It is, however, key to determine whether the communities would be prepared to move to a new area.

Having a voice

He also believes that good relationships between industry, government, and the community are important to make a positive difference in the area. A platform is needed where the people’s limited voice will be heard in policy making. 

“The most effective way to find a solution is to listen to the people in the community. Give people the information and find out from them which of these options are possible within their local context. And do not prescribe. One needs to understand the community and its values,” he adds.

When there is understanding between the different role players and when the community has a voice, the park resources, if managed properly, have a chance to provide long-term sustainable benefits to the people of the area.

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
