G
netum africanum
Welw. is a plant species of Central and Western Africa with high nutritional, medicinal and economic
value. In Cameroon, its leaves are recognized by the forestry administration as a special product. It is one of the most
commercialized non-wood forest products. Strong demand combined with destructive harvesting techniques has resulted in
rarity in its distribution area. The objective of this work is to evaluate the temporal stock in order to assess the economic value
of the agro forest system of
Gnetum africanum
in Massoum boum village, located at some 30 km of Douala town, the economic
capital of Cameroon. An ethno botanical survey was carried out both with the
Gnetum africanum
harvester of the agro forest
system in two markets in the city of Douala. An inventory of
Gnetum africanum
stems was carried out at an overall sampling
rate of 9.52%. A total of 7429 stems of
Gnetum africanum
was inventoried, for an average density of 6190 stems/ha. The height
and the diameter structure were described. A temporal potential consisting of 77994 stems, 1,50,62,985 leaves and 558.9 boots
of
Gnetum africanum
was estimated for a temporal economic value of XAF 447120 for the whole agro forest system.
