Research paper thumbnail of Inventory of Active Landslides and Landslide Hazard Assessment Using Field Techniques and Remotely Sensed Data: A Case Study from Balkhila Sub-Watershed (Uttarakhand, Himalaya)

Journal of Geography, Environment and Earth Science International, 2018

IRS-IC LISS III, RESOURCESAT LISS-IV remote sensing data products along with Survey of India (SOI) topographical sheets accompanied by field investigations were used to generate a landslide inventory map of the study area. Such type of information on slope stability of the area could be useful for explaining the known existing landslide, helping to make emergency decisions and relieving the efforts on the avoidance and mitigation of future landslide hazards in the area.

Research paper thumbnail of Assessment of status and biomass of Swertia angustifolia : a high value Himalayan medicinal plant

Studies on population assessment and biomass variation in selected populations of Swertia angusti... more Studies on population assessment and biomass variation in selected populations of Swertia angustifolia were undertaken in west Himalaya. Low population density across the surveyed populations indicates poor availability of the species in study area. Species showed random distribution and higher frequency of occurrence in most of the population, which is the indicator of better potential of the spe-cies in these sites. Density was positively correlated with biomass. The biomass showed peak value in senescence phase and thus has positive consequences of harvesting for the survival of the species.

The present study analyzes variability in reproductive characters of A. glauca. The reproductive parts were found having significant positive correlation with altitude (e.g., number of umbellets /umber r= 0.857, p<0.05; umbel diameter r=0.735, p<0.05).

However, the present scenario shows a decline in these traditional, plant-based health-care practices. These age-old practices are conservation-oriented and have tremendous potential to uplift the state economy. The excessive extraction of medicinal plant resources for use in the pharmaceutical industry has resulted in ruthless destruction of natural populations of medicinal plants. This work attempts to assess the current status of knowledge of medicinal plant resources of the state. It also focuses on the importance of documenting traditional knowledge and practices related to conservation and sustainable utilization of medicinal plants in Uttaranchal. A collaborative work plan involving scientists, government institutions and nongovernmental organizations is suggested for preserving the traditional knowledge system and practices, conservation of medicinal plants and upliftment of the rural economy of this mountain state.

An approach is set up for prioritization grading of the importance of medicinal plants that is based upon the knowledge of local communities about the species. The study of Himalayan medicinal plants in general and Angelica glauca Edgew. in particular reveals that the utilization pattern, traditional knowledge base and trade of medicinal plants show trends that are not ideal for sustainability in the Indian Himalaya. The research attempts to integrate the analysis of several aspects of Himalayan trade in medicinal plants to reveal the threat to the plants and to suggest ways to overcome the problem.
