Introduction

Assam is one of the eight states of north-east, India having great cultural as well as both floral and faunal biodiversity. This state is located between 24044’N to 27045’N Latitude and 89041’E to 96002’E Longitude, covering 2.4% of the geographical area of the country i.e.78,538 sq km. The annual rainfall ranges between 305 cm. max to 178 cm min. with an average of 211.76 cm. The temperature recorded in summer is 37°C maximum and 18°C minimum, and 26°C max. and 7°C min. in winter. The average humidity is 83.00%. The forest area of Assam is 28,748 sq.km. out of which 359 sq.km. come under water bodies and the total forest area covers around 32% of the total geographical area of the state. On the other hand, forest and tree cover is 36.67% of geographical areas including homestead forestland. Out of the total forest area, 3555 sq.km. are under various types of encroachment [1]. Assam is a region of diverse cultures and traditions, races, and ethnicities. The folk culture is still vital in this region. Most tribal communities still largely depend on non-timber forest products for their traditional system of medicine, household material, cultural need etc. Because of their scattered and far-flung settlements and problems arising due to transportation and communication, traditional medicine has remained as the most affordable and easily accessible source of treatment [2].

The NTFPs are the products of forest which include valuable food, fodder, fiber, medicinal plants, bamboos and canes, tannins and dyes, oils, gums, resins and leaves and many products of animal origin. Forest contributes to the environment climate, conservation of soil and regulation of water supplies, control of draughts and floods, improvement of landscapes, recreation etc. [3]. The NTFPs are an important source of income for the poor in many countries. In India, 50 million people are dependent on NTFPs for their subsistence and cash income [4]. The use of Non-Timber forest products is an age-old practice of human beings. In the upgradation of rural economics, the role and contribution of NTFPs are crucial because of their richness in biodiversity as source of food, fodder, fiber, fertilizers, herbal products, construction materials, cosmetics and cultural products of perfumes, medicines, paints etc. [5-8]. About 80% of the populations of the developing countries depend on NTFPs for their primary health and special nutritional needs. These are the direct benefits of forest. There are also some indirect benefits of forest as it protects the environment and trees maintain the fertility of the soil in many ways. They maintain a symbiotic relationship between the fungi and a higher plant root and also prevent soil erosion. It also contributes to reducing greenhouse gasses and associated global temperature rise by converting into carbohydrate through photosynthesis.

The non-timber forest products are also called minor forest products because they have minor significance. These are categorized as edible products, grasses and grazing, fodder trees and shrubs, bamboo and canes, fibers and flosses, animal products, leaves, miscellaneous products etc. Gathering NTFPs from the local forest for getting cash income or used by indigenous people can be traced back thousands of years ago [9]. Forest is an inseparable part of the tribal people. They are almost completely dependent on forest for food, shelter, medicine and clothing. They collect NTFPs like roots, tubers, flowers, fruits, fibers, gums, resins, dyes, tannins, honey and wax etc. to fulfill their day to day requirements. A little work has been carried out for the tribal people regarding upliftment of their economic status through the selling of NTFPs.

The present study attempts to document on the diversity and usage pattern of NTFPs among the different tribal groups of Upper Brahmaputra valley, Assam, India. This Paper also helps to understand the role of NTFPs in livelihood and economy of the tribal people in the study area.

Materials and Methods

The study was carried out in the Upper Brahmaputra Valley Agro-Climatic Region of Assam. This region is consisting of four districts namely Golaghat, Jorhat, Sibsagar, Dibrugarh and Tinsukia covering an area of 12,692 square km. (Figure 1). The region is bounded by hills and Brahmaputra River which flows down gradually from the hills of Arunachal Pradesh and Nagaland. Soil is mostly alluvial and having the characteristic of deciduous tree, evergreen and semi-evergreen forest. The climatic condition of the region is damp and cool with annual rainfall more than 2600 mm. It is one of the most important tea growing areas of the world. The region is also showing both cultural and socioeconomic diversity with various indigenous ethnic/tribal communities. The major ethnic groups of this region are Tai-Ahom, Sutiya, Sonowal kachari, Muttock, Mishing, Moran, Deori, Tea tribes (Adivasi) etc. Moreover, many minority communities like Taiphake, Khamti, Turung, Aiton, Tiwa, Konayak, Singpho, Nocte etc. are also part of the socio-economic and cultural diversity of this region. All these indigenous groups of people of these regions have their own unique culture and tradition where they use different plant resources for their livelihood in their day to day life for different purposes. In the present study extensive field survey was conducted during 2014-2015 in the above mentioned region. The detailed household surveys were done using semi-structured questionnaire regarding the used pattern of NTPFs. From each selected village 30% households were sampled randomly. Further detailed information on NTFPs, plant species and their utilization patterns were collected through personal interview and group discussion with village headman and other knowledgeable villagers of different ages, groups and sex. The villagers were asked that what plant species were used as NTFPs, in what purposes and how they used them etc. Authentic identification was done with the help of different flora and monograph [10,11]. The collected specimens were preserved as herbarium and voucher specimens were kept in the department of Botany, D.R. College, Golaghat, Assam.

The people of this region are mainly dependant on agriculture for their food and economy, and these NTFPs play a key role in agriculture where people use this NTFPs as a raw material for constructing different materials which help in agricultural system. Moreover, the people of the study area use NTFPs as fire wood, house construction materials, edible food and as Medicinal Plants, insect repellents, Broom etc. The NTFPs used for medicinal purposes generally are used to cure diseases like fever, pain, stomach problem, ring worm etc. Sometimes the people use the whole plant while sometime only leaves, roots, fruits, stem and latex according to their needs and use. In the study the highest use of NTFPs recorded is as edibles like fruits (32.65%), followed by Leaves (30.62%), Whole plant (18.37%), Stem (12.24%), Roots (4.08%) and Latex (2.04%) (Figure 2).

Mostly poor and unemployed people collect and sell NTFPs in large quantities. They retain a large part of the product for their own use and sell the remaining part in the market. The income generated by the sale of NTFPs is utilized for buying cloths, shelter and other necessary items. Forest provides employment to the large population including Tribal people. During 1985 forest provided employment to about 10 million people in the primary sector. Forest and various forest activities help tribal people to improve their socio-economic condition by being employed for the collection, processing and marketing of various forest products.

Conclusion

The increasing demand for medicinal plant and other NTFPs threats the natural resource management for sustainable utilization [2,12]. Mainly, extraction of medicinal plants from the wild sources and destruction of forest for human settlement causes ecosystem imbalance and extinction of many important plant species. Therefore, now-a-days it is vital to cultivate or to domesticate wild species and practice their sustainable use. Transfer of technologies and adaptive research are needed to give adequate emphasis on the development of the NTFPs. Co-operation in research among the people and collaborative programs can help to avoid duplication and speed up the process of development of NTFPs. Along with it we must create interest among the people and specially the younger generation to conserve and to cultivate the non-timber forest product for the future earth and people otherwise these NTFPs will be extinct from this beautiful earth.
