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.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
