Abstract

Chorabari Glacier (6.6 sq. km) in the Mandakini River basin, a tributary of the River Alaknanda, Central Himalaya, Garhwal (India) has been monitored in terms of its length and frontal area (snout) changes for the period between 1962 and 2012. Global Positioning System, Survey of India toposheet (1 : 50,000) and ground-based measurements were used to obtain the changes in morphology and size of the glacier. The result shows that the frontal area of the glacier has shrunk by 1% and 344 ± 24 m length loss, with an average rate of 6.8 ± 0.5 m a^-1 from 1962 to 2012. The observed terminus records of Chorabari Glacier indicate that the positive mass balance can cause terminus advance in about a 17-year timescale. The lag time of glacier signal transferred from accumulation area to the snout by glacier flow is about 562 years. These observations as well as other studies carried out in the region show a significant reduction in glacier area. The increased retreat rate of the glacier snout is probably a direct consequence of global warming.

Abstract

To reduce the greenhouse gas (GHG) emission from rice and wheat cultivation several mitigation options have been suggested. However, economic impact of these technologies has been poorly documented. In the present study economic analysis of some emerging GHG mitigation technologies for rice-wheat system of the Indo-Gangetic Plains has been carried out. The experiment consisted of six combinations of wheat- rice crop rotation using eight treatments, including conventionally tilled wheat (CTW), zero tilled wheat (ZTW), transplanted puddled rice (TPR), dry direct seeded rice (DSR), intermittent wetting and drying (IWD), application of rice straw (RS) with ZTW and use of neem oil-coated urea (NOCU) in TPR and ZTW. Cost of various inputs and income from grain and straw were used for computing the benefit to cost (B : C) ratio in the different treatments. ZTW showed higher yield and B : C ratio compared to CTW along with reduction in fuel consumption during tillage operation. In spite of lower yield under DSR and IWD, saving of water, labour and energy in these treatments lowered the cost of cultivation and enhanced B : C ratio similar to TPR. Application of rice straw and NOCU also showed positive impact on crop yield. B : C ratio of rice-wheat system ranged from 1.62 to 1.86 in the first year and from 1.86 to 2.16 in the second year. B : C ratio was significantly higher in all the treatments in the experimented rice-wheat system compared to conventional system, i.e. CTW-TPR. The ZTW + RR - DSR (WR5) showed highest B : C ratio followed by ZTW + DSR (WR4) in both the seasons.

Abstract

Situated in the highly elevated areas well above 3000 m, where alpine shrubs and grasses are the dominant vegetation, rangelands provide diverse ecosystem services to local and downstream communities. Spread over more than a third of the globe and about 54% of the Hindu Kush Himalayan (HKH) region, these serve as the main feed resource for traditional livestock rearing systems in many parts of the world and include about 70% of the feed for domestic ruminants.

Abstract

Solar coronagraph mimics total solar eclipse by blocking the solar disk and enabling the observation of extended coronal atmosphere of the Sun. Visible Emission Line Coronagraph (VELC), on-board Aditya-L1 space mission, is an internally occulted solar coronagraph capable of simultaneous imaging, spectroscopy and spectro-polarimetry close to the solar limb. This payload is designed to study the coronal plasma and heating of the solar corona. Studying development, dynamics and origin of coronal mass ejections and measurement of coronal magnetic fields over active regions are other important science goals. VELC is designed to image the solar corona at 500 nm with an angular resolution of 5" over a field of view (FOV) of 1.05-3 R_o. It also facilitates simultaneous multi-slit spectroscopy at three emission lines, viz. Fe XIV (530.3 nm), Fe XI (789.2 nm) and Fe XIII (1074.7 nm) with a spectral resolution of 28 , 31 and 202 mÅ/pixel respectively, over an FOV of 1.05-1.5 R_o. The payload has a dual-beam spectro-polarimetry channel for magnetic field measurements at 1074.7 nm.

Abstract

Microwave technique was applied for the synthesis of Argemone biodiesel from Argemone oil under defined experimental conditions. The method presented has the potential to synthesize quality biofuel in time efficient manner. It also results in higher yield of biodiesel while decreasing the reaction time by almost 75% when compared with conventional heating method. The biodiesel produced was tested for various physico-chemical properties and found to maintain the quality as recommended by various specifications.Reduction in the wear scar diameter of low-sulphur diesel from 432 to 256 μm at a very low concentration of biodiesel (1.0%) was an additional advantage to produce biofuel.

Abstract

The Indian Himalayan Region (IHR), spreading from Arunachal Pradesh in the east to Jammu and Kashmir in the west and covering 530,795 km² of geographical area, holds a special place in the mountain ecosystems of the world. The IHR is also known as the third water tower of the earth and supplies water to a larger part of the Indian subcontinent. Due to the rich water potential of the IHR and the ever-increasing energy demands of the country, the Government of India recognized that hydropower potential needs to be harnessed to the maximum for economic development.

Abstract

A globally threatened and variegated fern, Pteris tricolor Linden, is listed under different threat categories of the International Union for Conservation of Nature and Natural Resources (IUCN)¹. It has a restricted distribution in far North East India, Myanmar and Yunnan province of China^2,3. Its discovery, however, was accidental; Linden⁴ found this species growing spontaneously in the Malaccan orchid consignment at his nursery in Bruxelles (Brussels), Belgium, and described it as a new species with accurate, spectacularly coloured illustration (also reproduced by Fraser-Jenkins⁵). Its Malaccan origin^4,6–9 is rejected because till date it has not been reported from there. Later, it was postulated that it has more likely come from Myanmar¹⁰, or alternatively from China or NE India; but in all three countries it is a rare species.

Abstract

Knowledge of carbon (C) pools in soils is helpful in devising practices for efficient carbon management in intensive cropping systems. Carbon fractions of soil organic carbon are used asan indicator for land-use induced change in soil quality. The present study evaluated carbon pools under Terminalia chebula(chebulic myrobalan) based agroforestry system supplied with different nutrient sources, viz. farmyard manure, poultry manure, vermicompost, wheat straw and inorganic fertilizer (NPK @ 100:80:60). Carbon fractions, viz. very labile (C₁ frac), labile (C₂ frac), less labile (C₃ frac) and non-labile (C₄ frac), were analysed at 0–15 and 15–30 cm soil depth. The higher value of C₁ frac (13.8%), C₂ frac (4.8%), C₃ frac (8.3%) and C₄ frac(11.1%) were recorded under agroforestry as compared to open system. Among the nutrient sources, all the carbon fractions were higher under 100% integrated nutrient sources as compared to controlled treatment. Microbial biomass carbon (MBC) was recorded higher (298.31 μg g^–1 ) under agroforestry system compared to the open system (290.63 μg g^–1 ) at 0–15 cm. Among the different nutrient sources, higher MBC (458.66 μg g^–1 ) at 0–15 cm and lower (340.59 μg g^–1 ) at 15–30 cm soil depth was recorded in 100% integrated treatment.Thus, agroforestry-based land-use types and integrated nutrient management are more efficient for soil health and carbon management in Himalayan foothills.

Abstract

The Himalayan ecosystems are a hotspot of biodiversity; they also regulate climate and provide livelihood to over a billion people. These ecosystems are stressed owing to urbanization, over-exploitation of forest resources including rampant removal of medicinal and aromatic plants, and rapid threat from illegal trade in wildlife and poaching ¹ . Cumula-tive effects of these have resulted in enhanced species extinction and high hazard frequency² . In order to address these threats and conservation issues, the Government of India (GoI) in 2017 initiated the project SECURE Himalaya ‘Securing livelihoods, conservation, sustainable use and restoration of high range Himalayan ecosystems’ – a landscape-based approach towards the holistic con-servation of biodiversity and sustainable utilization of wild resource base. This project is a collaboration between the United Nations Development Program (UNDP), Ministry of Environment, Forest and Climate Change (MoEFCC), GoI and Global Environment Facility (GEF). It focuses on the Greater and Trans-Himalayan landscapes of India encom-passing the states of Jammu and Kashmir, Himachal Pradesh (HP), Uttarakhand and Sikkim. It is well known that these land-scapes are the habitat of snow leopard, wild prey species and their associated habitats as well as various remote agro-pastoral communities.

Abstract

Agroforestry has great potential for carbon (C) sequestration among different land uses of the Himalayan region, India. However, our knowledge of C sequestration in particular, agroforestry system around the world is poor. Therefore, we conducted a study to understand biomass accumulation and carbon allocation in different components of the agroforestry system. The highest stem biomass was recorded in Eucalyptus tereticornis (69.43 ± 0.90 Mg ha^–1), branch biomass in Populus deltoids (5.04 ± 0.35 Mg ha^–1), leaf biomass also in P. deltoids (2.21 ± 0.12 Mg ha^–1), and ischolar_main biomass in Albizia procera (14.01 ± 0.44 Mg ha^–1). The highest (81.01%) C allocation was recorded in the stem of Toona ciliate, branch of P. deltoids (5.73%), leaves of E. tereticornis (2.93%) and ischolar_main of Anthocephalus cadamba (16.83%). The highest CO₂< mitigation (160.5 ± 2.55 Mg CO₂ ha^–1) and C sequestration (45.33 ± 0.60 Mg ha^–1) were recorded in E. tereticornis. The highest wheat crop biomass (11.85 ± 0.23 Mg ha^–1) and C stock (3.59 ± 0.05 Mg ha^–1) were recorded in P. deltiodes. However, soil carbon stock was recorded in E. tereticornis (37.5 ± 3.52 Mg ha^–1). Thus, trees on farmlands with crops are suitable for biomass production and C allocation in different components under changing climatic scenarios.

Abstract

The composition of species can play an essential role in reducing the atmospheric carbon dioxide. Forest trees are an important part of the functioning of the terrestrial ecosystem, predominantly in the cycling of carbon. However, tree physiology is much less studied than crop physiology for several reasons: a large number of species, difficulty in measuring photosynthesis of tall trees or forest species. This study aims to establish the relationship between physiological plant functional traits (photosynthesis rate, transpiration rate, stomatal conductance, leaf chlorophyll and carotenoid content) with soil carbon stock in Pinus roxburghii forest of Garhwal Himalaya. The present findings revealed that photosynthesis rate, chlorophyll a, chlorophyll b and carotenoid content positively correlated to the soil carbon stock. The different regression models also showed that photosynthesis rate with water-use efficiency, stomatal conductance and carotenoid content is a good predictor of soil carbon stock in Pinus roxburghii forest. Physiological plant functional characteristics are thus crucial for regulating the carbon cycle and ecosystem functioning in Garhwal Himalaya.

Abstract

On 7 February 2021 at 10:30 am, a huge amount of slurry material flooded the Rishiganga catchment, resulting in excessive flow along the valley. The main cause of this flood was the dislocation of a huge rock mass approximately 540 m wide and 720 m long from the main rock body, which slipped down towards the Raunthi Gadera valley floor, causing massive devastation in the areas such as Raini, Tapovan, and Vishnuprayag. This event was not expected and was the first event in history when a flash flood occurred in winter. In this study, we tried to answer two major questions which are not been explained so far that are related to this disaster. These questions are (i) why did this event occur in winters? (ii) where did so much debris and water come from?. This study clearly answers these questions based on field observations

Abstract

Nanofertilizers have emerged as an effective alternative to traditional fertilizers. They contribute to increased agricultural production by increasing input efficiency and reducing relevant losses. The present study was carried out at the G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, India, during 2016–17 to study the effect of synthesized zinc oxide nanoparticles (ZnO NPs) on the growth and productivity of wheat and field pea crops. The results of the study revealed that significantly greater wheat and field pea plant height was recorded with 10, 20 and 50 ppm concentration of ZnO NPs, which decreased at 100 ppm concentration. A significantly higher yield of wheat was recorded at 50 ppm ZnO NPs concentration (3.28 ± 0.51 g plant^–1), followed by 20 ppm (3.05 ± 0.43 g plant^–1), which was at par with 100 ppm (3.02 ± 0.45 g plant^–1), and the minimum at 10 ppm concentration (2.70 ± 0.34 g plant^–1) over control. A similar trend in yield was observed for field pea. With respect to the mode of application, a higher yield of wheat was observed in the seed-soaking method (3.05 ± 0.43 g plant^–1); however, in the case of field pea, a higher yield was observed using foliar spray (6.21 ± 0.52 g plant^–1) method of ZnO application. Higher Zn content was observed in 50 ppm concentration for wheat (42.39 mg g^–1) and field pea (26.00 mg g^–1). The higher Zn use efficiency in terms of physiological efficiency was recorded at 20 ppm concentration (1.46) for wheat and 10 ppm (5.51) for field pea. Hence, it can be concluded that the applied ZnO NPs have stimulating effects on wheat and field pea crop growth and yield through increased zinc content in plants, zinc uptake and zinc use efficiency.
