Scoping the Need of Mainstreaming Indigenous Knowledge for Sustainable Use of Bioresources in the Indian Himalayan Region.

Globally, Indigenous Knowledge Systems (IKSs), which have evolved through rigorously tested methods and practices, are a testimony of human intelligence and endurance. The diversity of goods such as food, beverages, herbs, etc., and its associated systems, which form an integral part of modern cuisine and healthcare systems, are deeply rooted in IKS and immensely contributing to overall well-being of mankind. The present study is an attempt to document and understand the contribution of indigenous and local knowledge to biodiversity conservation and management. Appreciation to the value of traditional and indigenous knowledge is globally recognized for their principles of coexistence and sustainable use practices. Past studies indicate a strong relationship between indigenous knowledge and sustainable development goals. This knowledge is valuable not only to dependent communities, but also to the modern world for ensuring food security and human well-being. The documentation of such valuable knowledge is therefore fundamentally essential for mainstreaming and strengthening the discourses on sustainable ecosystem management, and to address the preponderance of poverty among indigenous communities. Amid the changing scenario of consumption and the trend of revisiting nature-based solutions, the IKS hold a tremendous scope of engaging the community people in sustainable harvest and utilization of natural resources.

Vegetation dynamics and soil nutrient availability in a temperate forest along altitudinal gradient of Nanda Devi Biosphere Reserve, Western Himalaya, India.

This study examined forest structure, composition, and regeneration patterns of two sites, Tolma-Lata-Raini (TLR) and Bhyundar-Ghangaria (BG). Both sites are located within the temperate zone along the altitudinal gradient between 2,800 to 3,400 m asl of Nanda Devi Biosphere Reserve (NDBR) in the Western Himalayan Region of India. We recorded a total of 223 species of vascular plants (Angiosperm, Gymnosperm, and Pteridophytes) within the study area. Of the recorded species, plants within the family Rosaceae were dominant (17.69%), followed by Asteraceae (14.97%) and Ranunculaceae (12.93%). Betula utilis had the highest tree density (724 and 324 individuals ha-1) and species cover (44% and 36%) at both TLR and BG sites, followed by Pinus wallichiana (24%) and Cedrus deodara (15%), respectively. In BG site, 56% of tree species showed fair regeneration (i.e., seedling density > sapling density ≤ adult density), 22% good (i.e., seedling density > sapling density > adult tree density), 11% exhibited poor (i.e., species survived only in the sapling stage but not in the seedling stage), and the remaining (11%) indicated no regeneration. Comparatively, at TLR site, 40% of the tree species showed fair regeneration, 40% good, and the remaining 20% showed no regeneration. Across the two sites, species richness and diversity significantly decreased as the altitudinal gradient increased. Vegetation structure and soil properties also revealed differences between the southern and northern aspects. The baseline information generated in this study is helpful in designing effective conservation and management measures for these ecologically sensitive and important ecosystems. To effectively monitor changes in vegetation structure, species composition, and regeneration, we suggest that permanent vegetation plots with meteorological stations be established across the region for long-term monitoring of forest dynamics in response to the changing climate and anthropogenic pressures.

Scientific Appraisal and Therapeutic Properties of Plants Utilized for Veterinary Care in Poonch District of Jammu and Kashmir, India.

The importance of traditional and indigenous knowledge is acknowledged on a worldwide scale for its coexistence principles and sustainable use techniques. In view of this, the present study is an attempt to document the ethno-veterinary plants used by the tribal communities of Western Himalaya. This study also provides the scientific validation of herbal medicines used in ethno-veterinary practices through a reverse pharmacological approach. A total of 59 informants were selected through a non-probability sampling method. Detailed information on the medicinal plants used in ethno-veterinary practices along with their habits and habitats, part/s used, remedy preparation methods, additives/ingredients used during preparation and administration, dosages administered, and route of administration was collected. Data was analyzed for the Relative Frequency of Citations (RFC), Use Values (UV), Informant Consensus Factor (ICF), and Jaccard Index (JI). Further, a reverse pharmacological approach was used for scientific validations of the documented herbal knowledge of plant species. During the study, 56 plant species belonging to 54 genera and 39 families were documented. Asteraceae was the dominant family followed by Lamiaceae, Amaranthaceae and Fabaceae. Life forms were dominated by herbaceous species and leaves were the most common plant parts used. The highest Relative Frequency of Citations (RFC) and Use Values (UV) were recorded for Brassica rapa L. (Brassicaceae). The Pearson correlation coefficient between RFC and UV shows a strong positive correlation between the proportion of uses of a plant species within a sample of informants and the number of times that a particular use of a plant species was mentioned by the informant. Studies of the biological activity of ethno-veterinary plants can provide clues of promising leads for the isolation and identification of useful compounds that may be developed into pharmaceuticals for human welfare.

Saturated and Polyunsaturated Fatty Acids Rich Populations of Prinsepia utilis Royle in Western Himalaya.

The study aims to identify the fatty acid composition in Prinsepia utilis seeds collected from diverse populations of Western Himalaya, India. The seeds contained higher saturated fatty acid (SFA-43.09%; Average of all populations) followed by polyunsaturated fatty acid (PUFA - 29.57%) and monounsaturated fatty acid (MUFA - 25.53%), however variations among growing populations was measured. The correlation analysis reveals a significant (p < 0.05) negative connection between 10-Octadecenoic acid methyl ester (FA1), and altitude. Edaphic factors like available nitrogen showed significantly (p < 0.05) but the negative correlation with cis-11-Eicosenoic acid, methyl ester (FA10; p < 0.001), Docosanoic acid, methyl ester (FA11; p < 0.05), Heptadecanoic acid, methyl ester (FA14; p < 0.05), and Tricosanoic acid, methyl ester (FA29; p < 0.05). Antioxidant activity did not show any variation in the seed oil of different populations but varied among the concentrations (5-50 µL) used. IC50 values of DPPH activity was significantly (p < 0.05) varied connect ranged from 11.31-24.21 µL/mL among the different populations. These variations in fatty acid composition and IC50 values of the DPPH activity can be one of the indicators for selecting a promising population that would be harnessed for its potential in nutraceuticals and cosmeceuticals industries.

Source-dependent variation in phenolic compounds and antioxidant activities of Prinsepia utilis Royle fruits.

Prinsepia utilis, a wild-growing Himalayan shrub, is a good source of phytoceuticals, cosmeceuticals, and antioxidants. The present study is an attempt to investigate the effect of altitude and edaphic factors on phenolics and antioxidant activity in fruit pulp of Prinsepia utilis. The ripened fruits and soil samples were collected for detailed investigation. The fruits (pulp) were extracted in methanol for analyzing total phenolics and antioxidant activity using a spectrophotometric method and phenolic compounds by high-performance liquid chromatography (HPLC). Similarly, standard methods for soil analysis were used. Results reveal that altitude negatively correlated with total phenolics and flavonoid contents determined by a spectrophotometric method and with specific phenolic compounds determined by HPLC. For instance, Dwarahat population (PU-1) at lower altitude (1400 m asl) exhibited higher values of total phenolics and flavonoids, while total tannin was higher at Nainital (PU-6) population (2000 m asl). The antioxidant activity measured by 2, 2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) was found higher in Narayan Ashram (PU-9) population (2750 m asl), while ferric reducing antioxidant power (FRAP) was significantly higher in Badechena (PU-2) population (1600 m asl). Soil nutrients (edaphic factors) showed a good correlation among measured parameters. Neighbor-joining and principal component analysis identified phenolics and antioxidant-rich populations that can be utilized for collection of fruits from these populations.

Vibratory cue training elicits anticipatory postural responses to an external perturbation.

Anticipatory postural adjustments (APAs) represent the feedforward mechanism of neuromuscular control essential for maintaining balance under predictable perturbations. The importance of vision as a distal sensory modality in the generation of APAs is well established. However, the capabilities of external cues in generating APAs are less explored. In the present study, vibratory cue was investigated for its reliability among healthy individuals in generating anticipatory response under external perturbation in the absence of vision. Ten participants, in quiet stance, were provided with external perturbation in the form of pendulum impact in anterior-posterior (AP) direction under conditions of: both vision and vibratory cue absent; vision present but vibratory cue was absent; vision and vibratory cue both were present; only vibratory cue is present with vision being absent. EMG activities of the leg muscles and displacement of center of pressure (COP) in AP direction were recorded. The data were later analyzed and quantified in the time frame of anticipatory and compensatory phases. The results showed that with training, participants were able to generate significant APAs relying on the vibratory cue alone. Improvement in APAs was accompanied by minimizing the need for larger CPA and improved stability (COP displacement) under perturbation. The study outcome indicates the possibility of using vibratory cues for APA-based interventions.

Challenges and opportunities under COVID-19 on rural populace in Kailash Sacred Landscape (KSL)-India.

More than just a health crisis, COVID-19 pandemic has stressed across social, economical and emotional dimensions of human well being and health. The sudden enforcement although willful and honest, perpetuated a sense of insecurity and uncertainty as a result of livelihood loss, especially for the people employed in unorganized and private sectors across different urban centers of the country. The unexpected scenario not only caused widespread joblessness but also created varied conditions of psychological stresses foreseeing the less likelihood of returning of pre-COVID conditions. As an outcome of the pandemic, the involuntarily return of youth was seen as a boon for reversing the undesirable and unprecedented trends impacting the traditional rural dynamics. Present study is an attempt to highlights impacts, challenges and opportunities under and after COVID-19 on rural populace of Kailash Sacred Landscape (KSL) amid the sudden halt of remittances and jobless aspiring youth. A systematic approach was followed, where 16 villages in eight Blocks of KSL were assessed and migrants (n=815) were interviewed for compiling the information. Results revealed that COVID-19 has impacted (both positively and negatively) various sectors such as agriculture, tourism, overall family income, etc., as perceived by the respondents. Sectors like restaurants/shops, tourism, and agriculture emerged as potential cash generating avenues, with 30 %, 21 %, and 20 % respondent's perception, respectively. It is also revealed that in the absence of immediate alternatives, and policy intervention, villagers engaged themselves in the time tested traditional sectors of livelihoods or created their own niche by integrating traditional wisdom and acquired skills.

Determination of nutritional and energy value of Viburnum mullaha Buch.-Ham. Ex D. Don (Indian cranberry).

Nutritional and energy value of an underutilized wild edible Viburnum mullaha was determined. Vitamin analysis confirmed that the fruit contains high amounts of vitamin C (122.27 mg/100 g), vitamin B2 (0.14 mg/g), and vitamin E (13.47 mg/g). Macronutrient profile revealed that Viburnum mullaha is a rich source of carbohydrates (18.4 g/100 g), proteins (11.3 g/100 g), and lipids (18.4 g/100 g). It was calculated that 100 g of fruit berries can provide an average of 284.4 kcal (1185.7 kJ) energy. Analysis of magnesium, copper, iron, zinc, and manganese estimated by atomic absorption spectrophotometer confirmed that fruit berries of Viburnum mullaha can be utilized for developing various edible products. This is the first study ever on the biochemical analysis and nutritional value of this species; hence, it will provide nutritional statistics that scientific societies and the pharmaceutical and nutraceutical industries can use for their expanding investigations of the ultrasonically assisted technique described here in food and medicine.
