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

It is not every day you get to build a heart
2014-09-17

According to the World Health Organisation, heart disease is the leading cause of death world wide. Heart transplantations substantially outperform any other available treatment and extend life by an average of 15 years, but the shortage of donor organs and organ rejection still remain a challenge.

Getting closer to the day where it will be possible to produce human organs by using human cells, researchers at the University of the Free State (UFS) announced that they have successfully decellularized a primate heart.

Decellularization is the process of taking an organ and stripping its cells, leaving behind a framework of binding tissue. The organ can then be repopulated (recellularized) with the patient's own cells - a process considered to move heart research closer to the day when a patient can become his own donor.

This process was discovered in 2008 by American cardiologist, Dr Doris Taylor of the University of Minnesota, who decellularized and recellularized a beating rat heart in a laboratory.

World wide researchers already used the process of decellularization on rat and pig hearts, but the research team of the UFS is the first to use this on a primate heart.
