Africa could be called ‘the continent of mountain archipelagos’ for the unusual fact that most of Africa's mountains are isolated ‘islands’ rather than linear, continuous mountain systems such as those in Asia (e.g. the Himalayas), Europe (e.g. the Alps), and the Americas (e.g. Rockies and Andes). Even in Southern Africa, where we have the linear Great Escarpment (5 000 km long), this system is so old that it has been breached in innumerable places by erosion into a series of independent mountain blocks.

The result of this mountain disconnection is that Africa's mountains display biodiversity patterns more akin to islands than to mountains: rich, exciting, and unique, and full of very localised and interesting species. Likewise, mountain communities have established and evolved unique cultural ways of life and traditions in their particular mountains – isolated from other groups on other mountains. But in some mountains, internecine warfare and tribal conflict caused mountains to become boundaries rather than welcoming places. This was certainly the case during the Mfecane in Southern Africa, ultimately leading to the birth of Lesotho as the ‘Mountain Kingdom’. Colonialism took this to a new level, and – for most of Africa – mountains became international borders between empires, splitting ethnic groups into several nationalities and marginalising large segments of the population in these new countries. This same geopolitical situation continues today, with major implications for the sustainable management of mountain ecosystem services, natural capital, and socio-cultural sustainability in multinational contexts.

The Afromontane Research Unit (ARU) – a continental leader in African mountain research – seeks to explore these socio-ecological complexities in terms of sustainable development, providing research that can help to secure a positive future for the people, biodiversity, and goods and services provided by Africa's mountains. As part of its mission, the ARU is leading the way in encouraging a multidisciplinary community of practice that will drive a science-policy-action interface for Southern African mountains in decades to come. As virtually all of Africa's water comes from its mountains, this is a critical service to a region increasingly at risk from drought and the socio-political implications of rivers and taps running dry. 

Although the Qwaqwa Campus is the home of the ARU, the ARU is welcoming affiliations from across the UFS and beyond. Should you wish to become affiliated to the ARU, please contact the Director, Dr Ralph Clark at ClarkVR@ufs.ac.za. Visit the new ARU's website

UFS to host one of three world summits on crystallography

Prof André Roodt from the Department of Chemistry at the University of the Free State (UFS), co-unveiled a special plaque in Poznan, Poland, as president of the European Crystallographic Association, to commemorate the Nobel prize winner Max von Laue at a special Laue Symposium organised by prof Mariusz Jaskolski from the A. Mickiewicz University in Poznan.

Max von Laue, who spent his early childhood in Poznan, was the first scientist to diffract X-rays with a crystal.

2014 has been declared by the United Nations as the International Year of Crystallography, and it was recently officially opened at the UNESCO headquarters in Paris, France, by the Secretary-General of the UN, Ban Ki-moon. The International Year of Crystallography celebrates the centennial of the work of Max von Laue and the father and son, William Henry and William Laurence Bragg.

As part of the celebrations, Prof Roodt, president of the European Crystallographic Association, one of the three regional affiliates (Americas, Europe and Africa; Asia and Australasia) of the International Union of Crystallography (IUCr), was invited by the president of the IUCr, Prof Gautam Desiraju, to host one of the three world summits, wherein crystallography is to showcase its achievements and strategise for the future.

The summit and conference will take place on the Bloemfontein Campus of the UFS from 12 to 17 October 2014 and is titled: 'Crystallography as vehicle to promote science in Africa and beyond.' It is an ambitious meeting wherein it is anticipated to bring the French-, English- and Arab-speaking nations of Africa together to strategise how science can be expanded, and to offer possibilities for this as nestled in crystallography. Young and established scientists, and politicians associated with science and science management, are the target audience to be brought together in Bloemfontein.

Dr Thomas Auf der Heyde, acting Director General of the South African Department of Science and Technology (DST), has committed some R500 000 for this effort, while the International Union of Crystallography provided R170 000.

“Crystals and crystallography form an integrated part of our daily lives, form bones and teeth, to medicines and viruses, new catalysts, jewellery, colour pigments, chocolates, electronics, batteries, metal blades in airplane turbines, panels for solar energy and many more. In spite of this, unfortunately, not many people know much about X-ray crystallography, although it is probably one of the greatest innovations of the twentieth century. Determining the structure of the DNA was one of the most significant scientific events of the 20th century. It has helped understand how genetic messages are being passed on between cells inside our body – everything from the way instructions are sent to proteins to fight infections, to how life is reproduced.

“At the UFS, crystallography finds application in Chemistry, Physics, Biology, Mathematics, Geology, Engineering and the Medical fields. Crystallography is used by the Curiosity Rover, analysing the substances and minerals on Mars!

“The UFS’s Departments of Chemistry and Physics, in particular, have advanced instruments and important research thrusts wherein X-ray crystallography has formed a central part for more than 40 years.

“Crystallography has produced some 28 Nobel prize winners over the past 100 years and continues to provide the means for fundamental and applied research,” said Prof Roodt.
