Traditional Utilization of Bamboo in the Central Siwalik Region, Nepal.

Bamboo are the fastest growing perennial woody grasses that have versatile applications. Most of the local people inhabiting the riverine area of the Siwalik region of Nepal rely on bamboo products for economic benefits and medicinal uses. Our objective was to identify the diversity of bamboo species, their ethnomedicinal practices, and economic and ecological importance. Data were collected by direct observation, key informant interviews, participatory rural appraisal, inventory technique, focus group discussions, and a household survey using semi-structured and structured questionnaires. We recorded four genera and nine species of bamboo, of which eight species have been used for agriculture, five for medicine, four for construction, food, fodder, artifacts and religious purpose, three for river embankment, and two for ornamental purpose. As the local people in the study area were deprived of medical facilities, using traditional herbal medicine to cure various diseases was a common practice. The inhabitants responded that they use bamboo-based primary ethnomedicinal care even against snake and scorpion bites. Similarly, they use bamboo young culm for reducing body weight and control diabetes. The value of the informant consensus factor was found to be maximum for the bamboo against snake and scorpion bites (1.0) and minimum for weight loss (0.81). This study concludes that the traditional utilization of all kinds of bamboo in the region is vast despite their less diversity. The recorded bamboo species are used not only for food and fodder but also in preparing artifacts, soil nutrients restoration in the fallow land, construction materials for the rural people, river embankments, and religious and spiritual purposes. Therefore, if grown on a large scale, bamboo can provide sustainable benefits for the local users and ecological aspects. Bambusa tulda and Dendrocalamus strictus have a broad spectrum of pharmacological agents. Considering the multifaceted application of bamboo in the Siwalik area, it is worthwhile to encourage the local people to bamboo plantation, which would contribute to supplement their household requirements and be one of the alternative livelihood options.
