The suggestions from Mourizio is very important because most of the government think biodiversity resources as a source of revenue and issue permits of resource collection to the traders, not to the local and indigenous communities. The traders consider profit rather than the traditional knowledege, culture or beliefs, and collect excess resources illegaly. By the way, resources are denuded and local communities are deprived from their traditional rights.
National policies, acts and guidelines yet to be reviewed from the perspective of livelihood-based collection, not trade-based.
