Abstract
A study was carried out in the Mounts Mandara to assess the diversity of edible plant species, to identify the use of the edible products, and to determine their socio-economic value. Interviews of a sampling population were conducted randomly in 5 zones with 5 villages each and in rural and urban markets; a sample of 1020 persons was interviewed to evaluate and quantify the various products and determine their flows. The results showed that the edible plant products used in the area were: fruits, leaves, flowers, seeds, tubers, roots, barks and stems. These products were harvested from 61 plant species belonging to 29 families in which 54 species were fruit trees, 11 species produced leaves and / or flowers, 4 species produced seeds. The total annual quantity of products harvested was 1080.9 t in which: fruit (725.62 t); leaves (97.5 t), flowers (1.96 t), and seeds (255.82 t). The seeds of Parkia biglobosa were the most useful part by the populations of Mounts Mandara making “dawa-dawa†some traditional aromatic for a sauce. Exploited products were an important source of food and income for the people. Annually, exploited products generated at whole of 60 783 975 F CFA. The fruits were sold for 17 542 375 F CFA, the seeds yielded 36 676 900 F CFA, the contribution of the leaves was 5 452 820 F CFA and that of the flowers was 724880 F CFA, dawa-dawa brought, very popular, bring in a modest sum of 787 000 F CFA. Local people were developing interest in exploiting different bush products. The exploitation activities of the various products were intensifying; the requested species must be domestication to ensure the sustainable management.
Highlights
In the sub-Saharan African countries, most of the populations lives in the rural zones and are characterized by an ambient poverty
The present study generally aims to determine the diversity of edible plant species and their socioeconomic value for sustainable management
Edible plant products exploited in the Mounts Mandara In the Mount Mandara region, there was enumerated various edible wild plant products exploited as far as fruits, leaves, flowers, seeds, tubers, barks, roots
Summary
In the sub-Saharan African countries, most of the populations lives in the rural zones and are characterized by an ambient poverty This population is confronted to the insufficiency of the agricultural production to satisfy their daily requirement out of food and to ensure their well been. Non-timber forest products refer to biological resources other than timber and industry that are harvested from natural or man-made forests (Aubé 1996, Peters 1997) In plants, they include various organs such as: leaves, stems, bark, roots, bulbs, rhizomes, tubers, fruits and seeds, edible fungi (Tabuna, 1999). They include various organs such as: leaves, stems, bark, roots, bulbs, rhizomes, tubers, fruits and seeds, edible fungi (Tabuna, 1999) They provide rural populations with the products they need to survive (Ndoye and Perez 1998, Tabuna 2000).
