Spatial point pattern of the baobab (Adansonia digitata) in semi-arid savanna, Southeast Zimbabwe
Species distribution modelling based on bioclimatic variables to understand habitat suitability and changes in range dominates studies on the spatial distribution of baobabs, which limits our understanding of how the small-scale plant–plant interactions influence the spatial point pattern of this keystone species in semi-arid regions of sub-Saharan Africa. Here, we investigated the spatial distribution of the baobab in two protected areas, Chipin…
Archetypes of Climate-Risk Profiles among Rural Households in Limpopo, South Africa
More frequent and intense climate hazards, a predicted outcome of climate change, are likely to threaten existing livelihoods in rural communities, undermining households’ adaptive capacity. To support households’ efforts to manage and reduce this risk, there is a need to better understand the heterogeneity of risk within and between communities. The Intergovernmental Panel on Climate Change revised their climate vulnerability framework to incorp…

Aiming for the biodiversity target with the social welfare arrow
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 Limpopo Province, South Africa. The WGG has high plant biodiversity (661 species in 192 ha), which include…
Use of the Stinkbug, Encosternum delegorguei (Hemiptera, Tessaratomidae), for Food and Income in South Africa
The use of Encosternum delegorguei, an edible stinkbug with high nutritional value, is restricted to three distinct groups of people in the northeast of South Africa, the Bolobedu, the Mapulana, and the Vhavenda. The two latter groups consider stinkbugs a seasonal delicacy, whereas the Bolobedu do not enjoy eating stinkbugs but sell them in Thohoyandou and surrounding villages to the Vhavenda. Structured interview schedules with 106 harvesters in…
Comparative ethnoentomology of edible stinkbugs in southern Africa and sustainable management considerations
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 Bolobedu using them for commercial purposes. Structured interview schedules and observations with 106 …
Quantifying the Trade in Cycads (Encephalartos Species) in the Traditional Medicine Markets of Johannesburg and Durban, South Africa1
Plants for Peace? Conflict Management in the Development of Ten South African Outreach Nurseries
Volume and financial value of species traded in the medicinal plant markets of Gauteng, South Africa
The demand for traditional medicinal plants and products in South Africa has created an extensive cross-border industry involving thousands of harvesters and traders. The market values of individual taxa vary considerably. Pricing structures fluctuate between markets and over time as the cost of harvesting species varies depending on a gatherer's access to the resources and the proximity of markets to the harvesting sites. This paper estimates tr…
Factors influencing prices of medicinal plants traded in the Lowveld, South Africa
There has been limited research into pricing and consumer behaviour in the informal sector, an understanding of which is critical to effective management of extensively traded wildlife resources. This paper explores factors influencing prices of wild-collected medicinal plants traded in the Lowveld, South Africa. Resource management decisions relating to medicinal plants are often based on the high price/kg values of certain species, and the assu…
Valuation of communal area livestock benefits, rural livelihoods and related policy issues
Land Cover and Use Changes in Relation to the Institutional Framework and Tenure of Land and Resources in Eastern Tanzania Miombo Woodlands
Monetary valuation of livelihoods for understanding the composition and complexity of rural households
The Fuelwood Crisis in Southern Africa — Relating Fuelwood Use to Livelihoods in a Rural Village
Plant Resources Used for Subsistence in Tsehlanyane and Bokong in Lesotho
Direct use values of communal resources in Bokong and Tsehlanyane in Lesotho
This paper presents a comprehensive assessment of the contribution of communal resources to households in Bokong and Tsehlanyane in Lesotho. It argues that communal resources are an extremely important element in the livelihoods of people in the study area. It uses households as units of analysis in order to gain an understanding of the role that communal resources play at the micro level before any extrapolations are made to the regional and nat…
