1.1 Research background
Vietnam is a traditional agricultural country with more than 70% of the population workingin agriculture, of which a large proportion of agroforestry in mountainous areas, agriculture - ruralareas - farmers occupy an important position in the economy and Vietnamese society. Themountainous areas of Vietnam are inhabited by ethnic minorities with resources and livelihoodsdirectly dependent on natural resources, mainly forest resources and land. However, these resourcesare depleted and degraded due to the pressure of population growth, shifting cultivation, timberexploitation for consumption and industrial production. These adverse changes make it even moredifficult for poverty reduction and economic development efforts. The life of the communities istherefore still very difficult, especially the ethnic minorities in and near the forest areas. The majorchallenge for the sustainable management of forest resources and land in the mountainous areas ofVietnam is the protection and development of resources along with the reduction of poverty forlocal people.
Non-timber forest products include products derived from organisms other than timber,exploited from forests, forest land and trees. Many non-timber forest products are used forproduction and people's life. Hundreds of thousands of tons of bamboo are used in pulp and paperprocessing industry, tens of thousands of tons of medicinal plants are used each year. Non-timberforest products are also valuable exports and export value of non-timber forest products. Theexploitation and processing of non-timber forest products has attracted hundreds of thousands oflabors, mainly in rural and mountainous areas, contributing significantly to hunger elimination andpoverty reduction in forested localities. In the off-season, farmers often go to the forest to collectforest products to earn money to buy food and consumer goods, and to pay for children's medicineand education. In addition, non-timber forest products are also a daily source of food for households:bamboo shoots, forest vegetables, etc. Therefore, developing non-timber forest product productioncontributes to hunger eradication and poverty reduction in ethnic minority and mountainous areas,protect and sustainably develop forest resources, improve people's lives and contribute to thenational economy development.
