Detailed analyses of the chromosome meiotic behaviour and of mitotic metaphase chromosomes (2n = 32), as well as stainability studies of pollen fertility, were carried out in order to determine the cytological status of amphidiploid Trifolium repens L. (Dutch white clover). In amphidiploid (allotetraploid) Trifolium repens L., diploid-like meiotic behaviour of chromosomes was found, with no multivalent formation, and a normal karyotype with a single pair of chromosome having a secondary constriction was observed. These characteristics indicate favourable genetic and cytological stability in nature, and high pollen fertility further enhances its usefulness in breeding.

The extraordinary knowledge of indigenous people about their immediate environment and natural resource base can be a great asset for conservation of biodiversity. The current study aims to investigate an indigenous method of grazing management through temporary confinement of Mithun (Bos frontalis) of whole village community in a well selected area in the forest during the cropping and growing season. The whole system is called Lura and practiced by Galo tribes of Eastern Himalayan region of India. Every year Lura management committee is formed that selects a new site based on number of Mithuns, forage availability, time period and several other key criteria without affecting flora-fauna diversity and rare medicinal plants. The practice checks continuous, free, random and selective grazing by Mithuns. It prevent continuous disturbance of soil surface due to treading, during growing and rainy seasons that avoid soil erosion and compaction, and facilitate seedling germination and the invasion by plants. Change of site, provide resting period to the forages in the previous Lura site especially during growth stage that allow them to renew and regenerate appreciably within 1-2 months. It also saves resources and time for construction of fencing in each Jhum and other agricultural site of each farmer. The confinement offers easy monitoring, protection and regular health assessment of the livestock. Thus, it is a multifaceted indigenous practice that ensures grazing management, biodiversity conservation, protection of standing agricultural crops and animal health management

The knowledge behind the culture and beliefs of indigenous community needs to be harnessed and should be used to complement the modern technologies and policies for better and sustainable use of biological resources and increase resilience of the sector associated. The main objective of the current research was to study Jhum (Traditional Shifting Cultivation System) and the cycles and culture associated with it. The study was done in northeast Himalayan region of India and phenomenological approach was used. The research reveals that Jhum is the component of traditional agro-ecosystem encompassing diverse set of knowledge and practices of indigenous and local communities embodying traditional life-styles relevant for the conservation and sustainable use of natural resources for their livelihood. The cycle associated with the system reflects the synergy of practices with the natural phenomenon and indicators. Contrary to common modern belief, Jhum is carbon sink, maintain soil health, preserve biological diversity and sustain local climate. Forest clearing during Jhum is not deforestation but forest modification allowing forest regrowth during sufficiently long fallow. Fundamentally, Jhum as a system is an integrated approach to establish agro-ecosystem in the difficult terrains of tropical hill regions that involve forest, soil, biodiversity and livestock management through their culture, tradition and rituals that coevolved with associated ecosystem. Instead of being threat to climate or environment, the system can provide deeper insight into the many different aspects of sustainable and climate resilient development; and the interrelated role of local peoples and their cultures.

Current study was undertaken to highlight the effect of pruning on improving vigor of old orchards and increasing performance in terms of fruit yield and quality under water and nutrient stressed condition of mid hills of Eastern Himalaya. Guava was taken for the case study and all the physical and chemical properties of the fruits and other attributes of plant were evaluated using standard methods under three pruning intensities (light, moderate and severe) and no pruning. The emergence of bud was earliest in severe pruning, number of buds per shoot was highest with light pruning and cumulative lengths of new shoots were found to be highest in severe pruning. Fruit yield, size and weight were found to increase with pruning intensities and lowest in case of no pruning. Regarding chemical properties, total soluble solids and total sugar found to increase with enhanced pruning severity and least in case of no pruning. Acidity was found to be highest with no pruning and decrease with increase in pruning intensities. Overall pruning found to have rejuvenating impact on aged trees due to better light interception leading to better photosynthetic rate, better nutrient and water supply with reduced canopy and better quality yields.

Climate change arising from anthropogenic driven emissions of greenhouse gases has emerged as one of the most important environmental issues in the last two decades. One of the most significant potential consequences of climate change may be alteration in regional hydrological cycle and river flow regimes. Increased temperature is expected to increase the peak flows in snowfed rivers of Himalayas. The changing pattern of regional temperature on flood peaks deserves urgent and systematic attention over a basin which provides an insight view of historical trends. Lower reaches of Satluj River is selected for the present study. Testing the significance of observed trends in flood peaks has received a great attention recently, especially in connection with climate change. The data series available was 48 years (1967-2010). The records were subjected to trend analysis by using both non-parametric (Mann-Kendall test) and parametric (linear regression analysis) procedures. For better understanding of the observed trends, flood peaks were computed into standardised flood peak indices (SFPI). These standardised data series were plotted against time and the linear trends observed were represented graphically. The analysis of flood peaks at different observation stations in lower reaches of Satluj River showed a large variability in the trends and magnitudes. The trend analysis results of flood peaks and gauge heights indicate that the flood peaks at all sites i.e. Rampur, Suni and Kasol show increasing but statistically insignificant trends. The trends in gauge height at all sites are also showing increasing trend but Kasol is statistically significant at 95% confidence level. The fast melting of glaciers, incessant monsoon rainfall and the synchronisation of the discharge peaks are the main causes of river floods. The past flood peaks will help us to observe the frequency of occurrence of floods in certain region and to determine whether the flood peaks in the past have been same with that of the present or whether there is any deviation in the trend in relation to climate change. Such studies will help in designing mitigation and adaptation strategies towards extreme hydrological events.

Subject and purpose of work: The study aims to assess the sustainability of rural areas of Western Himalayas during the year 2019. Materials and methods: Aquestionnaire-based survey was conducted in upper Beas Valley of Himachal Pradesh. A total of 101 individuals were interviewed and the questionnaire was filled by the surveyor. Results: Survey showed that high level of unemployment prevailed in the region with minimal monthly income. However, they engaged in agriculture and allied activities along with collection of non-timber forest products (NTFPs) to supplement their incomes. The proximity to protected areas led to frequent encounter with wildlife and such encounters increased after the commencement of Hydro Power Projects. Respondents believed that construction HPPs and expansion road network in the region has increased the occurrence of landslides; and many of them had lost their cultivated land due to landslides. Conclusions: The study showed rural areas of upper Beas Valley were moderately unsustainable.
