Subject: Seasonal variation of wave power potential in the coastal areas of India
Keywords: Coastal areas, power generation, significant wave height, summer monsoon, wave power potential
Abstract: Wave-power generation could be a feasible solution to the huge power requirements of a country like India having a long coastline. The present study provides details of wave characteristics and wave power potential during different seasons along the Indian coast using wave observations. Seasonal average of significant wave height (Hs) was computed near the coastal areas of India from the measured data. Hs varied in the range of 1.62-1.95 m and 1.38-1.39 m along the west and east coastal areas respectively, during summer monsoon. These high waves generate high wave power (>20kW/m) along the east and west coastal areas of India. The seasonal average of wave power obtained was high (12-19 kW/m) off the west coast of India, suggesting that the west coastal areas of India. The seasonal average of wave power obtained was high (12-19 kW/m) off the west coast of India, suggesting that the west coastal areas are suitable for power generation during summer monsoon. This study highlights that the average wave power is high (12-19 kW/m) during summer monsoon along the west coast and insignificant (<2 kW/m) during non-monsoon. Thus, the present study suggests employing a to hybrid arrangement of power generation using solar and ocean wave energies to solve the problem of energy deficit near the coastal areas of India.

Subject: Impact of data assimilation on calibrated WRF model for the prediction of tropical cyclones over the Bay of Bengal
Keywords: Data assimilation, model calibration, multivariate background error statistics, operational forecast tropical cyclones
Abstract: The main objective of the present study is to examine the impact of three-dimensional variational data assimilation utilizing the multivariate background error covariance (BEC) estimates, in combination with the model calibration, for the simulations of seven tropical cyclones over the Bay of Bengal region. The study indicates that the utilization of multivariate BEC in assimilation influences the model forecasts in terms of wind speed at 10 m height, precipitation, cyclone tracks and cyclone intensity. The assimilation experiments conducted with a previously calibrated model combined with a previously calibrated model combined with the control variable option 6 (cv6) of BEC have reduced the overall root mean square error (RMSE) of 10 m wind speed by 17.02 %, precipitation by 11.14 % , cyclone track by 41.93% and the intensity by 25.5% when compared to the default model simulations without assimilation. The best experimental setup is then used for the operational forecast of a recent cyclone Gulab. The results show an RMSE reduction of 18.61% in the cyclone track and 28.99% in intensity forecasts. These results also confirm that the utilization of cv6 BEC in the assimilation of conventional and radiance observations on a calibrated model improves the forecast of tropical cyclones over the Bay of Bengal region.

Subject: Analysing the implications of electrification of public transport buses in Pune city, India
Keywords: Air pollution, electric vehicles, greenhouse gas emissions, public transport, urban roads
Abstract: The urban road transport sector in India currently faces the challenge of increased travel demand, increased use of private vehicles, traffic congestion as well as alarming levels of air pollution. The consequent public health problems, energy insecurity resulting from oil imports and pressure to mitigate greenhouse gas emissions from the sector have also emerged as serious challenges for the country. Many cities in the world are considering electric buses for public transport as one of the potential solutions to address these issues. This article analyses the feasibility of introducing electric buses in the public transport fleet by estimating the financial burden that such a shift may entail, and the corresponding emissions it would mitigate. It also provides a methodology and illustrates the same for a city in India. The results indicate that which electric buses may not be financially viable at present and require state support and subsidies for operation, careful planning and phased implementation would make them a promising option for the future. The cost analysis indicates that for the immediate future, the replacement of air-conditioned diesel buses with similar electric buses in the fleet makes better economic sense. However, it is necessary to determine how the increased cost of using electric buses is to be distributed across the population of the city to avoid disproportionately burdening one section, i.e., bus commuters, with the cost of cleaning up the city’s air.

Subject: Bearing capacity of spatially variable unsaturated fly ash deposit using random field theory
Keywords: Bearing capacity, finite element limit analysis, geotechnical engineering applications, probabilistic analysis, strength nonlinearity, unsaturated fly ash
Abstract: The aim of the present study is to examine the bearing capacity of aseptically variable, unsaturated fly ash deposit, based on finite element limit analyses. Strength nonlinearity of fly ash, arising due to partial saturation, has been modelled based on the well-known van Genuchten (vG) fitting parameters, obtained from the water retention characteristics curve (WRCC). For the probabilistic study. WRCC fitting parameters and angle of internal friction of fly ash deposit have been considered as stationary Gaussian random fields within a practicable range of coefficient of variation and anisotropic correlation lengths. Random field has been generated based on the Karhunen-Loeve expansion method. Adequate numbers of Monte-carlo simulations have been executed to evaluate the probabilistic distribution of the bearing capacity, considering strength nonlinearity as well as random distribution of the input parameters. Influence of stationary spatial variation of WRCC fitting parameters and friction angle on the probability of failure of a footing resting on the fly ash deposit is presented and observations as study duly explained. The results of this study would be useful for practicing engineers to design a safe fly ash fill and therefore offer a sustainable solution for the bulk utilization of fly ash in geotechnical engineering applications.

Subject: Process-based modelling of soil erosion: scope and limitation in the Indian context
Keywords: Conservation measures, natural resources, process-based models, run-off, sediment yield, soil erosion.
Abstract: The conservation and sustainability of natural resources, particularly soil and water, are crucial for agricultural yield and livelihood. Soil erosion models simulate the influence of existing farm management patterns as well as soil conservation interventions affecting soil erosion rates and accordingly recommended appropriate management techniques. The erosion models might be helpful for forecasting soil erosion, sediment load and evaluating the effectiveness of conservation measures. Although numerous empirical, conceptual or physical process-based models are used to study soil erosion, they differ in respect of input data requirements, representation of physical processes, sediment yield, and limitations due to their spatial and temporal variations. Due to limitations in empirical models in describing the erosion process, some process-based models may be used to quantify the state of soil erosion in a region. Before use, the available erosion models must be evaluated and validated for local circumstances. In this respect, the present study has been carried out to provide a critical review of various soil erosion models used worldwide, having different climatic parameters for determining soil erosion rate, run-off and sediment yield status.

Abstract: Vaccines are the only currently available effective means to protect people from COVID-19 and reach herd immunity that restricts further spread of the disease. Vaccines require to be maintained in a cold chain which needs continuous electric power. While even the cities and large townships in the Indian power grid suffer from frequent power outages, a large number of areas are out of the grid and do not have the benefits of electric power. The poor and agrarian communities living in these areas need to be provided with vaccines as much as the urban populations that are being currently served. There are cellphone towers everywhere now, even in the off-grid areas. These towers have excess power which can be harnessed to run the cold chain in the off-grid places, as is being done in some African counties and Myanmar. The background, need and modalities for using power from the cell phone towers to run the vaccine cold chain in the off-grid areas, in the interests of rendering social justice, are discussed in this article.

Subject: Estimating minimum energy requirement for transitioning to a net-zero, developed India in 2070
Keywords: Decent living standards, greenhouse gases, human development index, minimum energy requirement, net-zero emission.
Abstract: Determining minimum energy consumption per capita to support high development is a crucial activity for energy planners and policy makers working within resource, environmental and budgetary constraints. A composite metric like the human development index (HDI) of a nation is positively correlated with its energy consumption .The present study focuses on the estimation of minimum energy requirement for India to attain net-zero and a HDI value of 0.9 by 2070.The final energy requirement for India to attain net-zero and a HDI value of 0.9 by 2070.The final energy requirement is found to be about 18, 900-22,300 Twh/yr, indicating more than three-fold rise from the current consumption. About 30-40% of the final energy may be consumed in the form of hydrogen, whereas the rest will be used directly as electricity. Rapid infrastructure creation for high development and extensive digitalization may require additional 4400-4800 TWh/yr in the initial phases of rapid growth.

Abstract: Natural gas (environment-friendly fuel) plays a critical role in meeting the global energy demand. Thus, an urgent question arises about its efficient storage and transportation. The most common gas transportation method is through pipelines (PNG); this is not always practical due to distance and accessibility restrictions. Compressed natural gas (CNG) technology is transportation and storage approach; yet safety problems and low capacity are the main disadvantages of this method. Although transportation of natural gas in liquefied form (LNG) is considered an acceptable approach for large-scale and long-distance applications, this technology requires cryo-temperature (-162°C) .It faces the problem of constant gas boiling, imposing restrictions on storage time.

Abstract: Fruit and shoot borer (FSB) –resistant Bt brinjal Event 142 with cry 1Fa1 gene have been approved for biosafety research level (BRL) –II field trials by the Genetic Engineering Appraisal Committee (GEAC), the competent authority in India. For regulatory compliance, systematic detection of genetically modified (GM) crop would facilitate monitoring for the presence of a GM event in the supply chain. Polymerase chain reaction (PCR) and real-time PCR are widely used for GM detection globally. Qualitative PCR and real-time PCR assays targeting cry1Fa1 transgene were developed and validated with acceptable specificity and sensitivity up to 0.01%. A multiplex (hexaplex) PCR-based screening assay simultaneously detecting five transgenic elements and endogenous gene was developed for Event 142. Construct-specific PCR reported herein could be employed for more specific detection. These detection assays would facilitate efficient regulatory compliance by checking unapproved Bt brinjal event in the supply chain and also address the concerns of the consumers to an extent.

Keywords: Dielectric surface, high-voltage insulators, leakage current, power lines, service life.
Abstract: High-voltage insulators are the most massive elements of an overhead power line. The task of determining their current state and especially their residual life is crucial to ensure the reliability of the entire line. The issues of high-voltage insulators operation, physical processes occurring in the insulation, as well as factors leading to degradation of the insulation are considered in this study. The possibility of using the leakage current values of insulators for the control of the insulation and prediction of its resource is substantiated. The results of experimental studies of the leakage current of high-voltage insulators depending on their service life are considered.

Subject: Key informant perceptions on wildlife hunting during the first COVID-19 lockdown in India
Keywords: COVID-19 pandemic, food security, illegal hunting, lockdown, wildlife
Abstract: We studied the effects of the COVID lockdown in India on illegal hunting of wildlife using on-line interviews with key informants. Household consumption, and sports and recreation were identified as the main motivations, and logistical challenges for enforcement, disruption of food supply and the need for recreational opportunities as key factors associated with increased hunting during lockdown. These insights were corroborated by the statements made by experts extracted from media articles. Our findings suggest that the lockdown potentially increased hunting across much of India and emphasize the role of livelihood and food security in mitigating threats to wildlife during periods of acute socio-economic perturbation.
