Abstract
Dipterocarpus alatus (Dipterocarpaceae) is native to the mainland of Southeast Asia, where its oleoresin is used by indigenous people for illumination and for waterproofing baskets and boats. In modern society it is used for paint, varnish and lacquer and the essential oil is used as a fixative in perfumes. This species is also important for its timber. Tapping, marketing and economic importance of this non-timber forest product in a Laotian village, is described here. Annual production of oleoresin per tapped tree is between 22.5 and 31.0 l and the price received by the tappers is US $0.30/1. The product represents a main source of cash income to many villagers and the recent approach by businessmen could indicate an increased demand. There are good possibilities to enhance revenues for the tappers by adding value to the product at the source.
Résumé
L’espèceDipterocarpus alatus est originaire de la zone continentale de l’Asie du sud-est, où l’oléorésin est utilisée par les populations indigènes pour l’éclairage et pour le calfatage des embarcations et des paniers. Dans la société moderne elle est utilisée dans la peinture, le vernis et la laque. L’huile essentielle est utilisée comme élement de base des parfums. Cette espèce est aussi importante pour son bois. La saignée, la vente et l’importance économique pour un village Laotien sont traités ici. Le rendement moyen atteint de 22.5 á 31.0 litres par arbre et par an, et les collecteurs recoivent 0.30 dollars par litre. L’oléorésin représente une source économique considérable pour de nombreux villageois et la recente interêt que les commerants apportent à l’oléorésin pourrait signifier une augmentation de la demande. Il y a des possibilités considérables d’accroitre le revenue des collecteurs, si la valeur du produit á la source est augmentée.
