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.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
