Africa’s mountains are being destroyed – not by global warming, but by small-scale farming caused by overpopulation on the continent.

This is according to Dr Willem Daffue, veterinarian, adventurer, explorer, and conservationist who delivered the first plenary keynote address on the first day of the Southern African Mountain Conference (SAMC2025). The conference, which follows a highly successful first conference in 2022, is currently taking place at the Champagne Sports Resort. It ends on 20 March 2025.

Comparing photos that he took 40 years ago in Ethiopia and the Democratic Republic of the Congo with more recent photos, Dr Daffue painted a dire picture of the future of Africa’s mountains and the unique animals found there.

Overpopulation

Dr Daffue works for the Himalayan Wildlife Project, tracks bears in the Karakoram Mountains, documents and photographs endangered species on a global level – such as the Javan rhino and Sumatran rhino. He is also involved in the Giraffe Project of the University of the Free State (UFS).

“Global warming has not yet affected Africa’s mountains. The rainfall in these areas actually increased. So has the population. Humans are destroying the mountains. The small-scale farmers have caused the most destruction. The reason for this is overpopulation.”

“Overpopulation is forcing people to invade national parks where they start farming for survival. These people are poor, uneducated, and is dependent on aid. All the animals in these areas are critically endangered.”

In his presentation, Dr Daffue talked about the Erta Ale, an active basaltic shield volcano in the Afar region of northeastern Ethiopia, the Simien Mountains in northern Ethiopia, as well as the Bale Mountains in the highlands of Ethiopia – with unique animals exclusive to the areas, including the wild ass, baboons, beisa oryx, Soemmerring's gazelle, Walia ibex, the golden jackal, and the Simien wolf.

Endangered animals

“Almost all the animals found in Ethiopia are endangered. It is the total destruction of nature. Only 4% of all mammals are still wild animals. 96% off all mammals on earth are humans and domesticated animals, and 70% of all birds on earth are chickens.”

“So, we are going to lose it. We are already past a point where we could save some of the animals and nature; it is an emergency but if we wake up now, we might still have a few things to save,” said Dr Daffue.

The answer is to curb the population growth, to educate the people, and to lift them out of poverty. Which is extremely difficult to do.

According to Dr Daffue, a conference such as the SAMC is extremely important, as it brings together different role players, including academics, researchers, communities, and policy makers. It helps in making plans, sharing knowledge, and getting policies out to people, the decision makers.

The conference

The Southern African Mountain Conference – conceptualised by the UFS Afromontane Research Unit (ARU), the African Mountain Research Foundation (AMRF), and Global Mountain Safeguard Research (GLOMOS) as a joint initiative between Eurac Research and the UNU Institute for Environment and Human Security – is unique, as it seeks to integrate the science, policy, and practitioner sectors for sustainable interventions in Southern African mountains.

Southern African mountains comprise those situated south of the Congo Rainforest and Lake Rukwa and include the mountainous islands of the western Indian Ocean. Thus, SAMC2025 is targeting Angola, the Comoros, the Democratic Republic of the Congo (southern mountains), Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namibia, La Réunion, South Africa, southern Tanzania, Zambia, and Zimbabwe.

The SAMC series is implemented by The Peaks Foundation (a non-profit company). SAMC2025 is held under the patronage of UNESCO.

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.
