Web spider abundance is affected by sheep farming in the Karoo

Impacts of livestock farming include effects on arthropods and a range of related ecological processes. Grazing by sheep may indirectly affect web spider populations by changing vegetation structures available for web construction, or directly by trampling the spiders or their webs. We tested these two potential impacts by surveying spiders along transects and found that…

Effects of short-term intensive trampling on Karoo vegetation

Plant growth forms likely respond differently to disturbances such as trampling. We investigated the trampling effect of 1 600 sheep encamped at night in temporary enclosures (kraals, corrals or pens), which were relocated weekly. To examine trampling effects and regeneration rates of the various growth forms we compared vegeta- tion composition, canopy cover and foliar…

Spatial, temporal and attitudinal dimensions of conflict between predators and small-livestock farmers in the Central Karoo

Conflict between predators and small-livestock farmers is a global phenomenon adversely impacting the preservation of wildlife, the well-being of livestock and human livelihoods. Such conflict is pervasive in the Karoo region of South Africa but its contemporary history and various causes remain poorly understood. In this study, we interviewed 77 small-livestock farmers in the Central…

The significance of traceability in consumer decision making towards Karoo lamb

As food markets have become more globalized, consumers have become more concerned about the origin of the foods they eat with a decreased confidence in the quality and safety of foods produced outside their local region or country. Traceability systems address this concerns and the importance of establishing a link between a product, producer and…

The food “quality turn” in South Africa: An initial exploration of its implications for small-scale farmers’

This article analyses the way the general turn from mass consumption to the increased qualitative differentiation of products – the “quality turn” – manifests in the South African agro-food system and explores its implications in terms of market access conditions for small-scale farmers in particular. While most retailers’ food quality positioning is in line with…

A Critical Analysis of the South African Mohair Marketing System…

The primary marketing of south Africa mohair has been the topic of much discussions and it has become a contentious issue since producer prices became unusually unstable, producer returns increasingly uncertain, and production consequently began declining. This dissertation has aimed to structure these discussions and issues and to critically analyse the South African mohair marketing…

Gradients in vegetation cover, structure and species richness of Nama-Karoo shrublands…

1. Gradients of animal impact known as piospheres tend to develop around artificial watering points, particularly in arid zones. Such grazing gradients represent a potential opportunity for differentiating the long-term effects of livestock activity from other environmental patterns. In this study, the impact of watering point provision on the plant cover, species richness and community…
