The neglected and underutilized species in the Northern mountainous provinces of Vietnam

Neglected and underutilized species (NUS) play a pivotal role in the improvement of nutrition, medicine, and income for rural populations in the Northern mountainous provinces of Vietnam. PRA and baseline tools were used to collect the ethnobotany information of the NUS and their practical uses through the traditional knowledge of a local culture and people in the three Northern mountainous provinces of Vietnam. The results showed noticeable values of seventy-seven NUS including 50 leafy vegetables, 9 root and tuber crops, 11 edible wild fruits, 3 legumes and 4 others (some species have defined as NUS, others have not yet defined as NUS). These findings would create a strong promotion for utilizing and conserving of genetic resources of NUS in the Northern mountainous regions of Vietnam.
