People And Plants: A Survey Of Economic Botanicals On The Kumasi Central Market

Abstract

Plants generally provide valuable functions in livelihood sustenance and indigenous knowledge on their utilization has been applied over centuries. However society So dependence on plant resources is threatened by rising environmental degradation especially in the tropics and the associated loss of indigenous botanical knowledge cannot be underscored. Traditional markets are useful sources on information on plants. This . paper reports on the ethno botany, availability and consumption trends of economic plants sold on the Kumasi Central market in the Ashanti Region of Ghana, as well as challenges encountered in marketing these resources. Structured questionnaire and inventory sheets were employed in a detailed documentation of information on the vendors and their products. Photographs of the products and specimens were also gathered, prepared and preserved in a herbarium at the Forestry Resarch Institute of Ghana. Information on 150 plant species belonging to 55 families was documented along with a taxonomic identification of new species. Nearly all plant species had multiple uses with approximately 57% and 20% usedfor medicinal andfood purposes respectively. Ninety-seven percent of the plants were non-timber forest products collected from the wild, and 30% of these were reported to have declined in supply as a result of degradation of vegetation. Demand has increased for 60% of the products, attributable to increased recognition and values that consumers currently attach to natural products mainly for medicinal and food purposes. With rising demand and declining supply of some plant species, the sustainability of the natural resource base is possibly threatened. This is because the sources from which these prodcuts are collected are usually unmanaged and harvesting methods, although rudimentary, may be destructive. Management interventions that would enable sustained exploitation of plant species collected from the ,wild, as well as the development of cultivation methods for key threatened species are imperative to aid biodiversity conservation and sustain the livelihoods of people relying on these resources for survival.
