Chapter
From 1979 Rustenburg’s economy was driven by platinum mining, but since 2007, despite some booms, it has gone into decline. This chapter, based on the stories of four respondents from Freedom Park, a low-income area of Rustenburg Local Municipality, reflects on the fickle nature of mining. We argue that the ordinary people of this city have shown r...

Wild-sourced foods are entrenched among African women as a survival resource, with the potential to be expanded. Instead of optimising food security, current linear economic growth models in South Africa favour large environment-degrading projects, such as special economic zones and mining, that increase the gap between the wealthy and poor sectors...

Indigenous knowledge systems encapsulate place-based truths and cultural wisdom that apply to education for sustainable development. The integration of indigenous knowledge systems into education for sustainable development school practice in South Africa and Japan was compared during exchange visits between researchers. Although the two countries...

This article describes our use of an online Future Creating Workshop (FCW) as a planning strategy to support our Global Climate Change Education Initiative (GCCEI). The GCCEI is an Educational Action Research project designed to provide the opportunity for students to discover how climate change acts to affect weather, health, economy, politics, an...

Worldwide, agroforestry has been shown to provide farmers and communities with a range of direct services such as food, livestock feed, wood and medicine as well as indirect ecosystem services such as pollination, pest and weed control, and soil formation and enrichment. These multiple benefits suggest that woody perennials, such as trees and shrub...
Article
The Eco-Schools programme in South Africa is the longest-running Education for Sustainable Development (ESD) initiative in Africa, which aims to enhance environmental literacy amongst students. This paper reports on a qualitative study involving a focus group of environmental educators working for a non-profit organisation. Through a Rapid Appraisa...
Chapter
Throughout sub-Saharan Africa wild-sourced foods, like edible insects, have been a way of life improving nutrition and providing a potential source of income. Unfortunately, natural areas are increasingly altered as time progresses through natural and anthropogenic factors that directly or indirectly alter ecosystems. Previously sacred places that...

The implementation gap between science, policy and practice has led to loss of biodiversity and ecosystem services throughout Africa and is described in a case study from Limpopo Province, South Africa. In 2006, the South African National Biodiversity Institute first highlighted the Woodbush Granite Grassland (WGG) in the Greater Tzaneen Local Muni...
Article
Full-text available
Underprivileged communities rely on beneficial plants for medicinal and cultural purposes as well as income generation. They are marginalised by land use planners, politicians and municipalities, resulting in biased integrated development and increased poverty. A case in point, is the Critically Endangered Woodbush Granite Grassland (WGG) in Limpop...

Article
Full-text available
The edible stinkbug Encosternum delegorguei is an obscure commodity derived from the cuisine of at least five ethnic groups in three sub-Saharan African countries. Derisive names and the obnoxious stench produced by stinkbugs belie the fact that they are nutritious and, once the odorous alarm pheromone is removed, a high demand delicacy. Annually a...

Indigenous knowledge systems began as the first humans used plants and animals for food, medicine, fuel and other uses. Particularly for animals, this inter-generational ethnozoological knowledge was transmitted orally and has not been thoroughly documented and checked. Yet indigenous knowledge is crucial to assess sustainability of bio-resources a...

: Insects, such as stinkbugs, are able to produce noxious defence chemicals to ward off predators, nevertheless, some ethnic groups have recipes to render them delicious. We provide an example of edible stinkbugs (Encosternum delegorguei) used by two locally separate ethnic groups in South Africa, the Vhavenda and Mapulana, with a third group, the...
Article
Full-text available
The use, processing, cultivation and trading of indigenous edible fruits was recorded across a rainfall gradient in the Mpumalanga lowveld. Three transects, each consisting of one village in a relatively high rainfall zone, one village in a low rainfall zone, and one intermediate, were sampled by means of 20 households per village. Nearly all house...

Little is known of the life history of the edible stinkbug, Encosternum delegorguei, although it is an important food for people living in north-eastern South Africa and southern Zimbabwe. The present study aimed to establish key elements influencing long-term sustainable harvesting. Outdoor insectaries of two sizes were constructed to observe: dai...

In the Bushbuckridge region of South Africa host preference and density of two woodrose-forming mistletoes, Erianthemum dregei (Eckl. & Zeyh.) V. Tieghem and Pedistylis galpinii (Schinz ex Sprague) was quantified in relation to land-use (harvested or unharvested), rainfall (high > 660 or low < 660="" mm="">–1) and catenal position (top or lower slo...

The Abe Bailey Nature Reserve, South Africa has been identified as a potential community resource reserve compatible with biodiversity conservation. As part of the planning and public participation phase this study investigated the potential for sustainably harvesting medicinal plants. Medicinal plant use data on local species, parts used and harve...
Article
Full-text available
Pedistylis galpinii and Erianthemum dregei produce woodrose outgrowtks at attach-ment points with host trees. In some rural areas of southern Africa, woodroses are sold as curios. The socio-economics related to woodrose harvesters were investigated via interview schedules and jield survey. Harvesting is not detrimental to hosts as only branches inf...
Article
The mistletoe Erianthemum dregei (Eckl. & Zeyh.) V. Tieghem produces a woodrose type haustoriurn on host trees. In some rural areas of southern Africa woodroses are harvested for their unique ornateness and prepared for sale as curies. Concern for the sustainability of mistletoe populations led to this study. Sclerocarya birrea (A. Rich.) Hochst ho...
Article
The use, processing, trading, cultivation and nurturing of wild edible herbs was recorded across a rainfall gradient in the Mpumalanga lowveld. Nine villages, in three transects across the prevailing west-east rainfall gradient, were sampled by means of 20 households per village. All households made use of wild edible herbs to some extent, with hou...

The formation of woodroses in Scierocava birrea (A. Rich.) Hochst, and Combretum collinum Fresen. in reaction to the parasitic mistletoes Erianthemum dregei (Eckl. 8 Zeyh.) Tiegh. and Pedisfyiis galpinii (Schinz ex Sprague) was investigated. Eight woodroses of varying sizes, and by implication age, were sectioned with the freeze microtome and the s...
Article
The use of Corchorus tridens for food and medicine is popular among rural communities in the Eastern Transvaal lowveld of South Africa. its prolific seed production, spontaneous germination, and distribution in water stressed regions suggest that cultivation of this species could be feasible. A study was initiated to investigate this. Seed coat sca...
