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.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.

Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.

The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).

According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.

In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.

“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.

H.E.S.S. has issued a complete statement about the paper published in Nature.
