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.

New world-class Chemistry facilities at UFS
2011-11-22

 

A world-class research centre was introduced on Friday 18 November 2011 when the new Chemistry building on the Bloemfontein Campus of the University of the Free State (UFS) was officially opened.
The upgrading of the building, which has taken place over a period of five years, is the UFS’s largest single financial investment in a long time. The building itself has been renovated at a cost of R60 million and, together with the new equipment acquired, the total investment exceeds R110 million. The university has provided the major part of this, with valuable contributions from Sasol and the South African Research Foundation (NRF), which each contributed more than R20 million for different facets and projects.
The senior management of Sasol, NECSA (The South African Nuclear Energy Corporation), PETLabs Pharmaceuticals, and visitors from Sweden attended the opening.

Prof. Andreas Roodt, Head of the Department of Chemistry, states the department’s specialist research areas includes X-ray crystallography, electrochemistry, synthesis of new molecules, the development of new methods to determine rare elements, water purification, as well as the measurement of energy and temperatures responsible for phase changes in molecules, the development of agents to detect cancer and other defects in the body, and many more.

“We have top expertise in various fields, with some of the best equipment and currently competing with the best laboratories in the world. We have collaborative agreements with more than twenty national and international chemistry research groups of note.

“Currently we are providing inputs about technical aspects of the acid mine water in Johannesburg and vicinity, as well as the fracking in the Karoo in order to release shale gas.”

New equipment installed during the upgrading action comprises:

  • X-ray diffractometers (R5 million) for crystal research. Crystals with unknown compounds are researched on an X-ray diffractometer, which determines the distances in angstroms (1 angstrom is a ten-billionth of a metre) and corners between atoms, as well as the arrangement of the atoms in the crystal, and the precise composition of the molecules in the crystal.
  • Differential scanning calorimeter (DSC) for thermographic analyses (R4 million). Heat transfer and the accompanying changes, as in volcanoes, and catalytic reactions for new motor petrol are researched. Temperature changes, coupled with the phase switchover of fluid crystals (liquid crystals -watches, TV screens) of solid matter to fluids, are measured.
  • Nuclear-magnetic resonance (NMR: Bruker 600 MHz; R12 million, one of the most advanced systems in Africa). A NMR apparatus is closely linked with the apparatus for magnetic resonance imaging, which is commonly used in hospitals. NMR is also used to determine the structure of unknown compounds, as well as the purity of the sample. Important structural characteristics of molecules can also be identified, which is extremely important if this molecule is to be used as medication, as well as to predict any possible side effects of it.
  • High-performance Computing Centre (HPC, R5 million). The UFS’ HPC consists of approximately 900 computer cores (equal to 900 ordinary personal computers) encapsulated in one compact system handling calculations at a billion-datapoint level It is used to calculate the geometry and spatial arrangements, energy and characteristics of molecules. The bigger the molecule that is worked with, the more powerful the computers must be doing the calculations. Computing chemistry is particularly useful to calculate molecular characteristics in the absence of X-ray crystallographic or other structural information. Some reactions are so quick that the intermediary products cannot be characterised and computing chemistry is of invaluable value in that case.
  • Catalytic and high-pressure equipment (R6 million; some of the most advanced equipment in the world). The pressures reached (in comparison with those in car tyres) are in gases (100 times bigger) and in fluids (1 500 times) in order to study very special reactions. The research is undertaken, some of which are in collaboration with Sasol, to develop new petrol and petrol additives and add value to local chemicals.
  • Reaction speed equipment (Kinetics: R5 million; some of the most advanced equipment in the world). The tempo and reactions can be studied in the ultraviolet, visible and infrared area at millisecond level; if combined with the NMR, up to a microsecond level (one millionth of a second.

Typical reactions are, for example, the human respiratory system, the absorption of agents in the brain, decomposition of nanomaterials and protein, acid and basis polymerisation reactions (shaping of water-bottle plastic) and many more.
