Abstract:
The economic size of the Indian economy and its status as one of the major global emitters of carbon emissions makes the country a good place to study the determinants of environmental degradation in India. The study aims at analyzing the impact of energy, export variety, and foreign direct investment (FDI) on environmental degradation in India in the context of environmental Kuznets curve (EKC) hypothesis. The long run relationship was found between variables of the study through a cointegration test, whereas long run estimates were obtained through cointegration and dynamic ordinary least squares (DOLS). Results of the study reveal that energy consumption, export variety, FDI, and income positively contributed to environmental degradation in India. Results also unveil that the EKC hypothesis does not exist in India. Causality analyses document unidirectional causality from income and FDI to environmental degradation, and bidirectional causality was witnessed between energy consumption and environmental degradation and between export variety and environmental degradation in the long run. The long run and the short run causality highlight that India has to forego the short run economic growth in order to improve its environmental quality and reduce global carbon emissions; however, it will not affect its long term economic development process.

Abstract:
The problem of rapid environmental degradation is one of the major issues which demands serious attention and response from almost every discipline of knowledge. The canon of environmental history has been formulated particularly to address this issue. Political, topographical and colonial histories have undoubtedly acted as major resources on the environmental history of South Asia. In recent years the pike in environmental degradation triggered by human actions have prompted to unearth environmental historicity in sources offering a critique of modern life and living and sources which act as documentations on such modern uprisings and its consequences. The present paper attempts to read Modern Indian poetry in English as documentation on the environmental historicity of Modern India. The paper attempts to assess the possibility of Modern Indian poetry in English with all its unconventionality to speak for the implicit and unarticulated aspects of human personality and society which necessarily remains implicit in the environmental discourse or narrative.

Abstract: Human rights not only in India but also around the world environment is intrinsically linked: safe, clean, healthy. A sustainable environment is essential to the enjoyment of our human rights; even though a polluted, dangerous and otherwise unhealthy environment potentially violates our human rights. Environmental rights are not abstract, distant and irrelevant concepts; are measurable, distinctive and functional aspects of society and its ecology. When environmental rights are violated, people and the planet suffer from reduced health and well-being. According to the Article 21 of the Indian Constitution that everyone on the country has the right to a healthy environment. This major decision is the result of decades of mobilization of various stakeholders. States must now meet their commitments and step up their efforts. This article aims to list relevant information, research, data and press releases and other institutions

Abstract:
This paper examined the dynamic linkages between tourism development, energy consumption, environmental degradation and economic growth in the context of the Indian economy. The short-run findings establish a chain-link between tourism development, economic growth, energy consumption and environmental degradation. Foreign tourist arrivals positively contribute to economic growth which in turn increases per capita energy use thereby raising CO2 emissions – a major cause of environmental degradation and consequential adverse effects on tourism development. The long-run findings, although inconclusive, are only indicative of short-run observations. Therefore, the policy focus should be on devising promotional strategies for encouraging the extensive use of clean energy for environmental protection. Such a policy base can be instrumental in fostering the development of India tourism and also, be pivotal for achieving sustainable economic growth.

Abstract:
This research paper explores the beginnings, significant turning points, and effects on policy and public awareness of the historical development of environmental movements in India. In India, environmental movements have arisen in reaction to several issues such as land degradation, climate change, industrial pollution, deforestation, and water scarcity. With protests against exploitative forestry practices and dam construction projects during the colonial era, modern environmental activism emerged. Its roots are in India’s rich cultural past, where reverence for nature has been engrained for millennia. Following independence, attention turned to projects fuelled by development, which created tensions between industry and conservation. Notable campaigns against environmental degradation and displacement include the Chipko Movement in the 1970s, in which peasants embraced trees to stop deforestation, and the Narmada Bachao Andolan in the 1980s, which protested against massive dam projects. To fully appreciate the intricacies, motivations, and consequences of environmental movements in India, it is imperative that we first grasp their historical trajectory. This will help us to better shape sustainable development paths for the twenty-first century.

Abstract:
The problem of environmental degradation due to deterioration of natural resources has become an important issue and is one of the burning problems in the 21st century in northeast India, especially in Mizoram. It is clear that deforestation, ground water depletion, soil erosion, decline in rainfall, river water pollution and volume decreases in dry season are the major threats to environmental degradation in this fragile terrain. Anthropogenic activities by land use changes due to settlement expansion, over exploitation of land and forest resources for intensive agriculture appear to be the major causes for the fast depletion of resources. Therefore, it is necessary to protect natural resources in order to mitigate multi-dimensional environmental degradation. This study is an attempt to analyze the causes and consequences of environmental degradation in this area based on the resources of land, water and forest. Implementation of appropriate measures like judicious use of natural resources, utilizing education to minimize economic backwardness and inclusion of community participation helps to mitigate environmental deterioration to great extent.

Full text
Abstract:
There is concern for the environmental protection of coastal zones throughout the developed and developing world. The major strategy against environmental degradation is the widespread introduction of the Coastal Zone Management (CZM) and Integrated Coastal Managment (ICM) regulatory processes. A great deal of effort is spent introducing, developing and refining the various ICM processes and structures that should reduce the likelihood of man made environmental catastrophe. ICM itself takes a functional view of management. An alternative and broader set of paradigms as presented by Burrell and Morgan (1979) provide a richer illustration of the process. Applying Burrell and Morgan's multi paradigm approach to the analysis of four case studies of environmental degradation on the Tamil Nadu coast in southern India, the regulatory framework is shown not only to be inadequate, but in fact adding complexity and exacerbating the sociological pressures that led to degradation in ways that will not be overcome by recent refinements of the existing process. An attempt has been made to identify the key issues that are crucial to identifying coastal projects that are 'at risk' of environmental degradation in India and a generic conceptual model is proposed. In the light of the results of this research study, a critique of ICM recommendations that have been commissioned by the Indian government's Ministry of Environment and Forests (MoEF) has been attempted and these are shown to be inadequate in terms of preventing environmental degratation.

Abstract:
Over the last two decades, there have been increasing concerns about environmental degradation and its consequences on the long-term sustainability of socio-economic systems around the world. The publication of the report of the Club of Rome in 1972, (Meadows et al. 1972) focused on the issue of limits to growth. Since then, there has been a profusion of literature and general models have been developed to address the causes of environmental degradation and the unsustainability of current patterns of growth (Ehrlich and Ehrlich 1970; 1990). Essentially these models used parameters that included population growth, consumption levels and aspects of technology, and their effects on the environment. While these models and studies were at a macro level that helped focus attention on the patterns of growth and their unsustainability, they did not provide insights into the mechanisms that were driving ecological change, nor suggest alternative models of growth. An entry point into the current study is to understand the mechanisms that drive ecological change. Motivated by concerns for environmental degradation, and the need to understand the mechanisms that drive ecological change, the study is situated in the academic domain of studies on human-nature interactions. The complex nature of interactions between human groups with their environment and their dependence on the situational context, requires that such studies be at a regional and local scale for which sufficient detail is available. This particular study is situated in the Nilgiri hills in the Western Ghats of Southern India for which such detailed information is available. The study reconstructs the ecological history of the Nilgiri area during the last 200 years, and from this laboratory of human-nature interactions, attempts to derive general patterns.

Abstract:
Cette recherche porte sur les origines et les effets de la dégradation de l’environnement dans le désert de Thar, au Rajasthan en Inde. Elle expose les processus politico-économiques qui conditionnent la gestion des ressources naturelles dans la région du Marwar depuis l’indépendance de l’Inde à aujourd’hui. Les modes de gestion des ressources environnementales et agraires dans le contexte du système jagirdari, un système foncier domanial qui prévalait dans la région avant l’indépendance de l’Inde, sont d’abord présentés. S’en suit une analyse de la manière dont les diverses idéologies liées au développement postcolonial ont reconfiguré le paysage socio-administratif et environnemental de la région. Ces transformations ont engendré des désordres écologiques qui ont donné lieu à une crise environnementale et agraire qui connaît son paroxysme avec les nombreux déficits pluviométriques qui sévissent depuis la dernière décennie dans la région. À partir d’une recherche de terrain effectuée dans la communauté de Givas, l’impact – au plan physique et métaphysique – de ces problèmes environnementaux sur la population locale est examiné. L’étude porte également sur les réponses à ces changements, soit les stratégies de subsistance adoptées par la population locale, de même que les interventions déployées par une organisation non gouvernementale et par l’État indien – à travers le National Rural Employment Guarantee Act (NREGA). L’analyse démontre que l’expérience de la dégradation de l’environnement, à travers ses effets et les stratégies d’adaptation qui s’en suivent, est tributaire de facteurs politiques, économiques et socioculturels et donc différenciée selon le genre, la classe et la caste.
This research focuses on the origins and the consequences of environmental degradation in the Thar Desert in the State of Rajasthan, India. It outlines the political and economic processes that have influenced how natural resources are managed in the region of Marwar since Indian independence. First are presented the modes of agrarian and natural resources management that were current during the jagirdari, the pre-independence land tenure system that prevailed in this region. This is followed by an analysis of how different ideologies of postcolonial development have reshaped the social, administrative and environmental landscape of this region. These changes have led to ecological disruptions which have given rise to an environmental and agrarian crisis that has now reached a critical point with the rainfall deficits of the past decade in this region. Based on field research conducted in the community of Givas, the implications – physical and metaphysical – of these environmental problems are analyzed. The study also looks at the responses generated in order to cope with these changes, namely the livelihood strategies adopted by the local people, as well as the interventions from a non-government organization and the Indian state – through the National Rural Employment Guarantee Act (NREGA). The analysis reveals that the experience of environmental degradation, through its effects and responses, is conditioned by political, economic and sociocultural factors, and thus differentiated by gender, class and caste.

Abstract:
Noise pollution in urban areas is recognized as a major environmental concern in India. The lack of infrastructure and fast paced life in major metropolitan cities of India has made the urban environment extremely crowded, busy as well as noisy and as a result the millions of people living in the major metropolitan areas are suffering from the impacts of noise pollution. Noise levels are escalating at such a rate that it has become a major threat to the quality of human lives. Direct links between noise and health have been established by research conducted over the past few decades. There are several causes for urban degradation such as population migration, environmental considerations not adequately being incorporated into master plans, uncoordinated and haphazard development, weak implementation of plans and laws and inadequate institutional competences and resource crunch. This paper discusses the causal factors, impacts and the different approaches adopted by the Central Government as well as some major State Pollution Control Boards to curb the urban noise problem and the need for looking into non-conventional solutions such as Ecocity programme to bring in visible environmental improvement.

Full text
Abstract:
Power generation in south Asia has witnessed a steep fall due to the shortage of natural gas supplies for power plants and poor water storage in reservoirs for low hydro power generation. Due to the current economic scenario, there is worldwide pressure to secure and make more gas and oil available to support global power needs. With constrained fuel sources and increasing environmental focus, the quest for higher efficiency would be imminent. Natural gas combined cycle plants operate at a very high efficiency, increasing the demand for gas. At the same time, countries may continue to look for alternate fuels such as coal and liquid fuels, including crude and residual oil, to increase energy stability and security. In over the past few decades, the technology for refining crude oil has gone through a significant transformation. With the advanced refining process, there are additional lighter distillates produced from crude that could significantly change the quality of residual oil used for producing heavy fuel. Using poor quality residual fuel in a gas turbine to generate power could have many challenges with regards to availability and efficiency of a gas turbine. The fuel needs to be treated prior to combustion and needs a frequent turbine cleaning to recover the lost performance due to fouling. This paper will discuss GE’s recently developed gas turbine features, including automatic water wash, smart cooldown and model based control (MBC) firing temperature control. These features could significantly increase availability and improve the average performance of heavy fuel oil (HFO). The duration of the gas turbine offline water wash sequence and the rate of output degradation due to fouling can be considerably reduced.

Full text
Abstract:
The construction industry is crucial to the global economy, significantly contributing to local economies and their overall productivity. This is evident in India also, where the construction sector has substantially driven economic growth and development. However, as this industry grows, it poses a significant risk to environmental degradation. While sustainability in construction industry is often investigated from the perspective of design and planning phases, there is also growing recognition of the importance of addressing sustainability during construction phase. A quantitative approach was utilised to investigate the degree to which sustainable practices during construction phase (SPCPs) are implemented in India. Data was gathered from clients, contractors, and consultants, and 40 responses were obtained from 147 respondents contacted. The level of implementation of SPCPs was ranked, and analysis of variance (ANOVA) was conducted to test the significant difference in perceptions among the three groups of respondents. The results indicated that five most frequently implemented SPCPs are: (i) health and safety inspection and auditing; (ii) health and safety training and education; (iii) preservation of archaeological sites, vegetation, and trees; (iv) construction equipment/machinery handling and utilisation strategy and (v) quality management systems. Some of the other fundamental sustainable practices that are under-implemented are: (i) construction noise/ vibration reduction measures; (ii) preassembly or off-site fabrication; (iii) sustainability assessment and recognition program and (iv) stormwater and greywater management plan. Findings of this study can provide guidance to construction industry practitioners in identifying areas that require enhancements, thereby fostering a collaborative approach towards advancing sustainable development goals

Abstract:
A mechanical device such as an aircraft gas turbine engine will in its lifetime of service show the effects of damage and deterioration. The damage to (and deterioration of) an engine has an adverse effect on the engine’s overall performance. It is therefore vitally important to predict the effects of deterioration on the performance of an engine and on the economic (fuel burn and engine life) implications from an operator’s perspective. Engine component degradation leads to performance deterioration and change, which requires the engine to run hotter and faster so as to meet the required thrust and aircraft performance. Increasing engine operating temperatures and engine speed result in increased creep and fatigue damage to the hot section components and increases the engine life cycle costs. One way of reducing life cycle costs is by better usage of the engine and involves being certain about the life potential of the engine and its components and how this life evolves with use. A sound understanding of how the engine life evolves and to predict remaining life requires understanding the engine’s operating environment and how component damage is sustained and accumulated. Knowledge about the engine condition and the likely stresses to which it will be subjected is required to analyse engine component usage and reduce degradation, raise safe-life limits of components and reduce maintenance requirements. This paper lays the foundation for the development of a prognostic tool that will capture and model the mechanisms of degradation, and predict levels of degradation based on engine deployment. The mechanisms that will cause degradation are assessed and integrated to establish the requirements of the tool. The paper discusses how degradation will affect component and engine performance and also the life of the engine.

Abstract:
Abstract The bearing prognostic analysis plays a critical role in improving the reliability of any rotational engine. In data-driven methods, used in such bearing prognosis, real time bearing vibrational data can be acquired from a set of sensors. In literature, many supervised learning techniques have been proposed to analyze this data. However, the labelled training data required for such a supervised technique is not always available in real life. Therefore, in this work, an unsupervised learning technique based on adaptive resonance theory 2 (ART2) has been used for bearing vibrational signal analysis. The benefit of this method is that no separate training is required for the prognosis purpose. The gas turbine is studied in this work is a GE MS 3002 used in natural gas transportation in Algeria. This method is used to study the bearing vibrational signal emitted at the high-pressure turbine side. The use of online method helps us updating the model, as new observations are available. This method also offers better performance under noisy environment.

Abstract:
India does not have large reserves of crude petroleum and spends a huge amount of foreign exchange for importing crude petroleum. The environmental degradation caused by burning of petroleum derived fuels is also causing an ecological imbalance. Research is carried world over on renewable fuels which could either be used as an extender or substitute to petroleum origin fuels and in this context alcohols such as ethanol and butanol have an immense potential. The earlier work on use of alcohols as a blend with diesel in the compression ignition engine has suggested reduction in emissions, however, problems such as phase separation and increase in fuel consumption has also been encountered while utilizing ethanol in diesel engines. To alleviate this problem, isobutanol has the potential to be used along with ethanol to make a homogenous blend without any phase separation and simultaneous advantage of alcohol being an oxygenated fuel which shall improve the combustion and reduce emission. The present study was carried out to explore the potential utilization of ethanol-isobutanol-diesel blends (containing up to 20% ethanol-isobutanol mixture in equal proportions) in compression ignition engine. Three blends were prepared having 5%, 10%, 20% ethanol-isobutanol mixtures respectively and calorific value, kinematic viscosity; specific gravity and density of blends were found to decrease with increase in ethanol-isobutanol percentage. The engine trial was conducted on an unmodified diesel engine to evaluate the performance and emission characteristics on ethanol-isobutanol-diesel blends and results were compared with baseline data of diesel. The results obtained from the engine trial suggested that brake thermal efficiency (BTE) increased and brake specific energy consumption (BSEC) decreased for the blends and considerable reduction in carbon monoxide (CO) and carbon dioxide (CO2) was observed with blends with a small increase in unburnt hydrocarbon (UBHC). The nitrogen oxide (NOx) and smoke emissions were also found to reduce for the ethanol-isobutanol-diesel blends.

Abstract:
Abstract Gas turbine degradation significantly impacts the operation, maintenance, and lifecycle cost of gas turbines. Multiple components within the gas turbine contribute to the overall degradation of gas turbine-based combined cycles, with the compressor component being the primary contributor. The compressor degradation is predominantly influenced by the quality of the intake air. Airborne particles tend to deposit on the compressor blades and vanes, increase surface roughness and potentially alter the blade shape, which can result in additional aero losses. Nowadays, customers are seeking gas turbines that exhibit less degradation, increased reliability, and greater availability. To meet these demands, many Original Equipment Manufacturers (OEMs) are focusing on improving the quality of intake air through the incorporation of highly efficient filters. Such filters reduce the deposition of air particles on the compressor blades, which leads to improved long-term compressor performance, increased gas turbine parts life, and reduced water wash cycles, thereby improving availability. However, the high cost of these filters and the increased compressor inlet pressure drop can reduce the overall performance of the Gas Turbine-based Combined Cycle (GTCC). Thus, it is essential to consider the impact on the overall lifecycle cost when selecting an appropriate filter class, which can guide the customer in making an informed decision. The first section of this paper discusses various classes of filters, their efficiency, and the resulting pressure drop. It also examines the degradation of Gas Turbine-based Combined Cycle (GTCC) associated with different air intake filters. The second section of the paper conducts a life cycle cost analysis of different filters using Siemens Energy’s in-house cost analysis tool called the Power Value (PV) tool. Although currently exclusive to Siemens Energy, the tool will be available to third-party users in the future. The analysis includes Levelized Cost of Electricity (LCOE), calculations for a 25-year period of GTCC plant operation. The analysis takes into account appropriate capital, fuel, maintenance, and electricity costs. This life cycle cost analysis provides valuable benefits to both customers and OEMs by comparing different air intake filter options and quantifying the total cost of each option, including capital, operational, and maintenance costs. This analysis enables customers and OEMs to identify the most cost-effective solutions during the project proposal and bidding phase. Additionally, this paper offers guidance on selecting suitable filters for various environments and highlights the impact of highly efficient filters on the decarbonization.

Abstract:
Pharmaceutical industries are experiencing a steady increase in both their numbers and demands, leading to a significant rise in the amount of waste they generate. This waste comprises various components such as organic compounds, excipients, and plastic containers. Unfortunately, a major portion of this waste is discharged into aquatic bodies through pipes, eventually reaching canal systems and ultimately the seas. This practice poses a severe threat to aquatic life, as it significantly impacts their habitat in a hazardous manner. One of the primary deleterious effects caused by pharmaceutical waste discharge is the elevation of the Biological Oxygen Demand (BOD) in the affected aquatic areas. This increase in BOD results in reduced oxygen availability for aquatic creatures, leading to mortality and ultimately causing a disruption in the natural balance of the ecosystem. Moreover, the accumulation of organic compounds from pharmaceutical waste leads to eutrophication, which accelerates the aging process of lakes, ultimately converting them into land. Another harmful consequence is biomagnification, wherein the concentration of toxicants increases as they move up the food chain through successive trophic levels. The continuous contamination of aquatic ecosystems by industrial waste is exacerbating the degradation of these fragile environments. However, the growing recognition of this issue has prompted research and implementation of various water treatment methods. These methods aim to mitigate the degradation rate and protect aquatic ecosystems from further harm. By employing advanced treatment techniques, it is possible to reduce the negative impact of pharmaceutical waste discharge and preserve the integrity of aquatic ecosystems. Efforts must be made to raise awareness among pharmaceutical industries about the importance of responsible waste management. By adopting sustainable practices and investing in environmentally friendly technologies, such as improved waste disposal systems and more efficient water treatment methods, the industry can significantly reduce its ecological footprint. Collaboration between regulatory bodies, environmental organizations, and pharmaceutical companies is essential to address this pressing issue effectively. With concerted efforts and a collective commitment to environmental stewardship, it is possible to mitigate the detrimental effects of pharmaceutical waste on aquatic ecosystems and safeguard the future of our planet's delicate aquatic habitats.

Abstract:
"The marsh represents a rare natural environment of its kind for a number of reasons. First, the marshes were the cradle of the Sumerian civilization and an environment that embraces a unique biodiversity. Its geography and vast area, which is equivalent to the size of a country like Lebanon, made it a resting place and provided food and reproduction for migratory birds. It is worthy of being included in the World Heritage List as one of the treasures of the world that must be preserved, but unfortunately, the Iraqi marshes have not been subjected throughout history to extensive and systematic drying operations, which reached 95% of their total area, as they were exposed to during the era of the previous dictatorial regime in the nineties of last century, which led to the emergence of a number of environmental problems that collectively led to the disruption of natural ecological balance through the loss of the ability to achieve the environmental balance and causing biological diversity damage . This is as a result of the lack of incoming water resources and the high percentage of salinity and pollution, which caused the death of huge numbers of wildlife and aquatic life, as well as the extinction of large numbers of them, causing a mass migration of the population of those areas to other areas that provide them with a minimum standard of decent living after they lost their main sources of livelihood represented by fishing and raising animals. The paper aims to present a study on the impact of the widespread and systematic drying stages that began after the Iran-Iraq war in the eighties of last century and culminated in the nineties, bringing the percentage of the remaining water from the marshes to 5% in 2002, and the extent of its impact on the destruction of the environment and biodiversity, which includes humans and animals, as well as migratory birds from Siberia to the Indian subcontinent, which lost their habitats and places for laying eggs and breeding. It will also present a number of solutions that will help reduce the environmental degradation that the marshes have been exposed to."
