Traditional health practitioners' practices and the sustainability of extinction-prone traditional medicinal plants

ABSTRACT

For centuries, traditional health practitioners (THPs) have used their indigenous knowledge (IK) in conserving medicinal plants and environments in order to maintain sustainability. Medicinal plants have played an important role in the healthcare system of Africa. With the rapid environmental, social, economic and political changes occurring in many areas inhabited by rural people, the danger exists that the loss of biodiversity from habitat destruction and unsustainable harvesting practices will cause some species to become extinct, threatening the availability of medicinal plants on a regional level. This article presents the findings of research conducted to investigate the sustainability of the harvesting practices of THPs, with specific reference to extinction-prone traditional medicinal plants in the study areas of the Limpopo province, South Africa. The main aim of the study was to determine the natural habitat of extinction-prone traditional medicinal plants, combining the insight of THPs with the ultimate goal of guiding research for the conservation, propagation and cultivation of traditional medicinal plants. The study adopted a qualitative research approach and data were collected using in-depth interviews. The findings indicate that the THPs’ practices are shaped by historical processes and local cultural values, social norms and their management strategies, which are influenced by a broad range of factors.     

Local plant use and traditional conservation practices in Nhema communal area,Zimbabwe

Abstract

This article is based on a study that was carried out in Nhema communal area in Midlands Province, Zimbabwe, with the main objective of documenting local plant use and traditional conservation practices. Data collected through household semi-structured and open interviews showed that 46 plant species in 40 genera and 24 families were mainly used for firewood, construction wood, food and traditional medicine. Other minor uses included using plant species for making mats, rope and shading. Firewood and construction wood ranked as the most important tree products used. The preferred plant species included: Julbernardia globiflora (Mutondo); Brachystegia spiciformis (Musasa); Terminalia sericea (Mususu); Brachystegia boehmii (Mupfuti); Combretum imberbe (Mutsviri); Combretum molle (Mubondo) and Burkea africana (Mukarati). Some of the highly preferred species, considered to be declining in the local environment, included Adenium obesum (Chisvosve); Azanza garckeana (Mutohwe); Brachystegia boehmii (Mupfuti); Brachystegia spiciformis (Musasa); Burkea africana (Mukarati); Combretum imberbe (Mutsviri); Combretum molle (Mubondo); Dalbergia melanoxylon (Mukonashanhu); Diospyros mespiliformis (Musuma); Elephantorrhiza goetzei (Ntorani); Julbernardia globiflora (Mutondo); Phragmites australis (Shanga; Poulzozia hypoleuca (Munanzwa); Pterocarpus angolensis (Mubvamaropa); Terminalia sericea (Mususu) and Uapaca kirkiana (Muzhanje). Highly preferred and declining species were characteristically large trees and shrubs. Local people are aware of the need to conserve plant resources in order to protect the environment and avoid the extinction of these rare species.Traditional conservation practices have substantially contributed to the conservation of plant species in Nhema communal area. The protection of indigenous timber, fruit trees, trees with social and cultural significance, the use of deadwood for firewood, the use of eucalyptus trees as construction wood and the occurrence of sacred woodland areas represented some of the traditional conservation techniques employed in Nhema communal area. These local practices demonstrate the dynamism and significance of African indigenous knowledge systems.
