Fracking into the Karoo economy
… the potential for shale gas extraction in the Karoo region of South Africa, every effort must be undertaken to understand what the effects this transformative industry may have. This paper attempts to explore what effects the industry may have on "small" Karoo towns by creating a demographic …

The sedimentary petrology of carbonate nodules in the Elliot Formation, Karoo Supergroup, main Karoo Basin (South Africa)
… part of the Elliot Formation (Stormberg Group, Karoo Supergroup) are often associated with genetically poorly-constrained carbonate nodules. The origin of carbonate nodules i.e., pedogenic versus diagenetic, is important as pedogenic carbonate nodules can be used as palaeoclimate indicators, …

Geochemistry of ferruginous clogging of Karoo wells
The main source of potable water in the Karoo is groundwater and thus any problems resulting from the abstraction of water or from diffifulties in abstractions of water are important. The iron clogging of screens, pumps and filter packs in supply wells is a worldwide problem and the consequences …

The short-term effect of rehabilitation on ecosystem services in the semi-arid succulent Karoo lowlands and the Little Karoo, South Africa
This study has shown that using active rehabilitation in combination with improved management strategies (e.g. rest from grazing) may induce recovery of certain ecosystem services within practically relevant time scales. However, these benefits might not be tangible for landowners or society as of …

The eco-ethology of the Karoo Korhaan Eupodotis Vigorsii
The following study was undertaken as part of the Karoo Biome Project (KBP) and sets out to investigate an aspect of karoo ecology that will contribute to a predictive understanding of both biotic and abiotic processes in the region for the development of meaningful management guidelines (Cowling, …

Micro-seismic observations in Leeu Gamka, Karoo, South Africa
… model was tested by varying the thickness of the Karoo supergroup to investigate the sensitivity of the depths of the earthquakes. An average hypocentral depth of approximately 6 km was calculated for the earthquakes, assuming a depth to the base of the Karoo of 5km. This places the earthquakes …

Land use and its impact on the Succulent Karoo
The Succulent Karoo biome (SK biome) is one of the 25 internationally recognized biodiversity hotspots in South Africa with approximately 1940 endemic species. The SK biome is, however, poorly conserved with less than 5% of the area under formal protection. It is also highly threatened by a range …

Studies of herbivory and vegetation change in Karoo shrublands
… landuse (extensive small stock ranching) in the Karoo against the background of relationships between indigenous plants and animals and to indicate how modification of herbivore regimes might affect this arid environment. Specific objectives were to determine how grazing by domestic livestock …

Karoo-Etendeka Unconformities in NW Namibia and their Tectonic Implications
In north-western Namibia the fills of the Karoo-Etendeka depositories can be subdivided into (1) a Carboniferous-Permian, (2) a Triassic-Jurassic and (3) a Cretaceous megasequence, each recording extensional periods related to successive rifting phases in the evolving South Atlantic. The tectonic …

Vegetation patterns and plant reproductive processes in the succulent Karoo
… and plant reproductive processes at the Tierberg Karoo Research Centre (33°1 0'S, 22°17'E) in the semi-arid southern Succulent Karoo, South Africa. It begins with an investigation into the roles of soil properties and competition in explaining variation in species distributions. The aim was to …

The investment in white benevolence in a small Karoo town
… the investment in 'white benevolence' in a small Karoo (Northern Cape) town and in ways that white residents present themselves, and position themselves discursively, as benevolent whites. Loosely located in social constructionist and postmodernist paradigms, this piece of work also attempts to …

The playful Karoo: digitizing the South African Anthropocene in video games
The Karoo in South Africa, with its distinctive natural landscape, remains an underexplored setting in video games. In this thesis, I reimagine Jane Rosenthal’s novel, Souvenir (2004), as a virtual reality video game, using its speculative, science-fiction vision of the Karoo to immerse the player …

Apophyllite weathering and the aqueous geochemistry of a Karoo breccia pipe
… Kopoasfontein, outside Calvinia in the western Karoo, South Africa. Groundwater abstracted from this breccia is uncharacteristically alkaline (pH 10) and high in fluoride (11 mg/L) for a natural water and the link between the groundwater chemistry and breccia pipe minerals has been investigated.
