The present study was carried out to investigate the population density, collection pattern and documentation of ethnobotanical knowledge of threatened medicinal plants (TMP) used by the inhabitants of Buffer zone villages in Nanda Devi Biosphere Reserve (NDBR). A total of 36 TMP species belonging to 20 botanical families have been identified that are used in the treatment of various diseases in traditional health care system (THCS). The average population density of TMP species was ranges maximum for Allium stracheyi (0.71–1.64 Ind/m2) followed by Pleurospermum angelicoides (0.52–1.56 Ind/m2) and Arnebia benthamii (0.82–1.41 Ind/m2), respectively in the Biosphere Reserve (BR). Allium stracheyi (0.98), Angelica glauca (0.91), Picrorhiza kurroa (0.89), Arnebia benthamii (0.87), Allium humile (0.82), Pleurospermum angelicoides (0.81), Bergenia stracheyi (0.80) with higher use value (UV) were the most used medicinal plants in the villages of BR. The study could be a pilot to reinforce the conservation measures across the Protected Area Network (PAN) by understanding the traditional knowledge of local inhabitants, dynamics of anthropocentric activities and its resultant impacts on medicinal plant diversity.

This paper examines sustainability of cash crops production systems as compared to traditional cereal cropping patterns in terms of their energy efficiency, ecological suitability, economic profitability, and social acceptability. The consistent supply of labor and energy are the most significant requirements for substantial growth of agricultural productivity in Himalayan region. For output–input ratio in terms of monetary efficiency, cash crops performed better (3.16–3.56) as compared to traditional crops (1.57–3.31), whereas the energy output–input ratio of traditional crops was found more efficient (1.63–4.72) as compared to cash crops (1.26–2.36). The monetary input and output analysis of Rabi crops was estimated to be 23.39% and 25.3% of Kharif crops, respectively; Similarly, variance in energy input (27.3%) and output (32.44%) analysis was observed between Rabi and Kharif crops, respectively. Energy input in the form of manure accounted >90% of total energy input, while other inputs (<10%) are contributed in the form of seeds, and animal and human power for all the crops. The study also highlighted the significance of traditional crops and factors responsible for their declining cultivation in the mountain region.

The paper scrutinizes that the changes in any sub-system (i.e. agriculture, livestock and forest) have direct impact on biophysical and social processes in village ecosystem of the central Himalayan region. In view of this, we studied the changes in spatial patterns of agricultural land use and dependency of agroecosystem on forest and animal husbandry over a period of two decades. Based on data analysis it was found that the cultivation of some traditional crops has either been abandoned in the area or declined by 25%–85% due to introduction of cash crops viz., potato, kidney bean and apple farming with acreage increased up to 51%–72% in the last three decades. Livestock population of different categories has declined drastically by 17%–75%, and has resulted shortage of farmyard manure, deterioration of soil quality and fertility which leads to un-sustainability of agriculture system. The changes in agrobiodiversity have led to the dramatic increase in soil loss and runoff from the croplands together with the increase pressure on forests. The economic evaluation of each crop showed higher monetary benefit from cash crops as compared to traditional crops. Among all the evaluated crops, the monetary output/input ratio was found highest (3.04) for kidney bean and lowest (1.26) for paddy. Changes in land use and management have improved household income but at the cost of forest degradation, less productive animal husbandry and loss of agrodiversity in the region. Therefore, there is an urgent need to bring desirable changes in agricultural policy, research, land use and efficient management of the resources for maintaining sustainability in agro and Himalayan forest ecosystem.

A large section of the population (70%) of Uttarakhand largely depends upon agricultural based activities for their livelihood. Rural community of the mountains has developed several indigenous and traditional methods of farming to conserve the crop diversity and rejoice agrodiversity with religious and cultural vehemence. Traditional food items are prepared during occasion, festivals, weddings, and other religious rituals from diversified agrodiversity are a mean to maintain agrodiversity in the agriculture system. Agrodiversity is an insurance against disease and extreme climatic fluctuations, as a coping mechanism in times of scarcity, as a means to enhance overall productivity of farms, as a source of critical nutrition and medicine in the Himalayan region. The different traditional system of agriculture and indigenous method of maintaining soil fertility, socio-cultural and religious rituals has saved many crops that are under threatened category. But all these system and practices are ignored nauseatingly in hill agriculture policy, where more emphasis was given for plain areas. Less emphasis is being put on local systems that rely on existing natural, human, and social assets such as biodiversity, traditional knowledge, and social capital underpinning collective action to ensure food security. Of late, development planners have realized the importance of appropriate technologies and therefore have stressed the need for on-site training, and capacity building of user groups in rural areas of the region. Rural technology demonstration and training center have been supposed as a means disseminating technologies enabling improvement in the yield potential of farms, income generation from off-farm activities, and conservation and efficient use of natural resources. There is a strong need to bring desirable changes in the agricultural policy, research, and development in reference to mountainous regions. The present paper describe present scenario of agriculture, traditional, and socio-cultural practices of retaining soil fertility and agrodiversity, policy dimensions, and strategies for management of the Himalayan agroecosystems.

The present study aims to document detail information of some of the selected wild edible having enormous potential for livelihood enhancement and socio-economic development by making a variety of value added products. To this end, some of the wild edibles of central Himalaya were selected and prioritized for harnessing their economic potential along with their detail information in terms of distribution, ethnobiology, phenophases and appropriate time of harvesting so as to make communities well aware about the resource availability and their harvesting period round the year. The cost-benefit analysis of each value added product prepared from selected wild edibles was worked out in detail and these analyses revealed that total monetary output, as well as the net return, is very high for all value added products prepared. Since wild edible fruits or other edible parts can be collected from wild free of cost except labour is involved in collection of these wild edibles bio-resources. In addition, information on a participatory action research framework & approaches for promoting participatory conservation of these wild edible species were also highlighted for appropriate management of these resources. The present attempt provides a practical example of sustainable utilization of wild edibles, their potential in livelihood improvement of local people, distribution and phenophases and availability in natural conditions, participatory conservation of these wild edibles may help policy planners at the regional and national levels to link livelihood/socio-economic development with conservation.
