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

The Physics Department at the University of the Free State (UFS) not only recently educated the local community about the mystery of dark matter, but shared its knowledge with a much wider audience.

The first screening of two planetarium full-dome films, The Dark Matter Mystery and Dark, at the Naval Hill Planetarium were concluded with a recording for the radio programme Sterre en Planete. During the discussion, led by Hennie Maas from RSG radio station, the audience asked questions that were answered by Prof Matie Hoffman, Associate Professor at the department, Sakkie van der Westhuizen, a PhD student in astrophysics, and Mariette Erwee from the School of Mathematics, Natural Sciences and Technology Education. The radio show was broadcast on 18 June at 19:30 on RSG.

Shows screened at special event
According to Prof Hoffman the planetarium hosts a movie premiere whenever pre-rendered shows are screened for the first time. The films shown on 10 June 2017 introduced viewers to the quest for dark matter. “Dark Matter makes up a huge part of the Universe, but it is a great mystery. We know very little about it. We cannot see it, and it is an area of enormous interest to scientists,” Prof Hoffman said.

Films sourced from European Southern Observatory
The event was attended by various stakeholders such as loyal planetarium patrons, UFS colleagues, and those interested in astronomy. The films were sourced from the European Southern Observatory, an organisation that makes planetarium content available online.

The Dark Matter Mystery took the audience on contemporary astrophysics’ biggest quest. They saw why astronomers know dark matter exists. Dark, directed by Peter Morse, is an adventure that goes to the very edges of contemporary cosmology and data visualisation, telling a complex scientific story with a touch of humanity.

The films will be screened at the Naval Hill Planetarium from time to time and those interested can visit Computicket for more info.
