5.1 Locale of Research

Based on the All-India assessment report regarding Climate Vulnerability Assessment for Adaptation Planning in India Using a Common Framework which identifies the most vulnerable states and districts in India with respect to current climate risk and the main drivers of vulnerability, the present study has been conducted in two relatively highly vulnerable states of India namely West Bengal (Vulnerability Indices:0.592) and Jharkhand (Vulnerability Indices: 0.674). It specifically comes under Agro-climatic zone III (Lower Gangetic plain region) and Agro-climatic zone VII (Eastern plateau and hilly region) respectively.

On the basis of Vulnerability Indices (Vis) different district of West Bengal classified into three categories i.e. relatively high vulnerability (0.59-0.69), moderate vulnerability (0.49 -0.59), and relatively low vulnerability (0.38- 0.49). Two districts, Malda (VIs:0.690) and Jalpaiguri (VIs:0.627) from highly vulnerable and three district Murshidabad (VIs:0.524), Dakshin Dinajpur (VIs:0.523) and Burdwan (VIs:0.497) from moderate vulnerable category were selected purposively for the present study. For satisfying the purposes three agroclimatic zones of the West Bengal, viz. Terai Zone (Jalpaigudi), Old Alluvial Zone (Murshidabad and Dakshin Dinajpur) and New Alluvial Zone (Burdwan) districts were taken into account for the assessment. Twenty respondents of two Villages from each Block i.e., Alipurduar-I of Jalpaigudi, Hilli and Gangarampur of Dakshin Dinajpur, Old Malda of Murshidabad and Barabani of East Burdwan were purposively picked for the research study.

The research setting is an important component of the research methodology. Research setting refers to the detailed information of an area where the study was conducted. The research setting can be seen as the physical, social, and cultural site in which the researcher conducts the study. In qualitative research, the participants are observed in their natural environments with a primary focus on meaning-making. The study area generally consists of a particular geographical area viz. a state, district, block, or gram panchayat area selected according to the benefit of the investigator who possesses adequate knowledge regarding the location, communication facility, the period of study, the availability of resources, etc. of the locality so that he can easily approach every corner of the area for data collection. Additionally, to comprehend people’s knowledge, attitudes, and behaviour more easily, investigators must have a fundamental understanding of their socio-demographic backgrounds. It is the environment within which studies are run that has important consequences for experimental design, the type of data that can be collected and the interpretation of results.

In any social science research, it is hardly possible to conceptualize and perceive the data and interpret the data more accurately until and unless a clear understanding of the characteristics in the area and attitude or the behavior of people is at commend of the interpreter who intends to unveil an understanding of the implication and behavioral complexes of the individual who live in the area under reference and form a representative part of the larger community. The socio-demographic background of the local people in a rural setting has been critically administered in this section. A research setting is a surrounding in which input and elements of research are contextually imbibed, interactive and mutually contributive to the system performance. Research setting is immensely important in the sense because it is characterizing and influencing the interplays of different factors and components. Besides the investigators must also have the basic knowledge about the socio demographic background of the people so as to have an easy understanding of their knowledge, attitude and behavior.

Research setting refers to the detail information of an area where the study has been conducted. The study area, generally comprises of a particular geographical area viz. a state, district, block, or gram panchayat area selected according to the convenience of the investigator who possess adequate knowledge regarding the location, communication facility etc. of the locality so that he/she can easily approach each and every corner of the area for data collection. Here. in this study the data collection was done mostly over telephone based on the interview schedule due to Covid-19 pandemic situation.

Introduction
The lives of the local population are disrupted by large-scale projects such as dam construction, mining, highway construction, or the designation of a national park, and they are frequently forced to relocate to a new location. Relocating individuals is a significant challenge as it diminishes their capacity to survive solely on their customary natural resource base and intensifies psychological strain. 33 to 56 million people have been displaced by 54 projects in India over the past 50 years.
Resettlement and Rehabilitation of People
Major projects like dams, mines, expressways, and other industrialization-related projects, as well as some conservation strategies like the creation of national parks, can cause disruptions to people’s lives and force them to relocate to an alternate location. Relocating individuals from their birthplace is a grave concern as it diminishes their capacity to survive only on their customary natural resource base, so adding to their psychological strain. It is difficult for the displaced individuals to adjust to a new lifestyle in a new location. Due to the indirect effects of the Green Revolution—the building of thousands of dams since India’s independence—thousands of people havebeen displaced. These impoverished locals have essentially paid for the construction of the dams. Even if the government has set enough time to relocate these displaced individuals and offer them a sufficient package for rehabilitation, this rarely happens.

Introduction
Food is a basic human need that is necessary for survival. The three main sources of our food are fishing, farming, and animal husbandry. Modern agricultural practices are unsustainable and employ enormous amounts of pesticides and fertilizers, which pollute the environment. October 16th has been designated as World Food Day.
Global Food Issues
• The rate of food production is not keeping up with the increasing demand.
• There are significant differences in the accessibility of wholesome food. Malnutrition is still a major issue for several tribes, particularly for women and children.
• Our rich soils are being depleted more quickly than they can replenish themselves.
• The conversion of wetlands, meadows, and forests to agricultural usage has resulted in significant ecological issues.
• There is an indication of exhaustion in our upland and marine fish resources.

One of the most significant natural resources is water. The water cycle sustains hydrological systems, which give rise to rivers and lakes and a range of aquatic habitats, through evaporation and precipitation. Only 3% of the water on Earth is freshwater, although making up 70% of the planet’s surface. Just 1% of this is useable water found in rivers, lakes, and subsurface aquifers, while 2% of it is represented by polar ice caps. Approximately 25% of water is used for industry globally, 70% of it for agriculture, and only 5% for residential consumption. In India, 7% is used for industry, 90% is used for agriculture, and 3% is used for household use. World Water Day is on March 22nd.
There are five oceans on Earth. oceans: the Pacific, Indian, Atlantic, Arctic, and Southern. One of the main saltwater bodies in the hydrosphere is called an ocean. The average salinity of the ocean is around 35 parts per thousand (ppt), or 3.5%. A river is a naturally occurring waterway that is longer than 18 meters (60 feet), usually freshwater, that flows toward one or more rivers, lakes, seas, or oceans. A component of the hydrological cycle are rivers.
A steam is a current-filled body of water that is contained between the banks of a stream and a bed. Typically, the watercourse’s width is under eighteen meters. It reunites disparate environments. Creeks are tributaries of streams that join rivers or other streams but do not flow into the ocean.
A lake, derived from the Latin lacus, is an inland body of water that receives waterfrom a river and is deeper and larger than a pond.

Retrospection

India is a unique country in the world with many religions and cultural diversity. Indian culture has been continuing through the ages because of its adjustability with others and openness. Unity in diversity is one of the major characteristics of Indian culture. It is a diverse nation where people of many religions live together peacefully. Religion in India is characterized by the diversity of religious beliefs and practices. In Indian history, religion has played an important role in the cultural set up of the country.

Hinduism is the main Indian religion and considered as a universal order, a way of life which is followed by the people. The origin for Hinduism is very old having no exact date of its inception. This is a belief and practices followed by people through the ages and considered as a process of humanity. The earliest known sacred text of Hinduism is ‘Vedas’ which dates back to at least 3000 BCE. However, it is believed that these texts are of divine origin and timeless. Hinduism was more philosophically and theoretically described in Upanishads, written roughly between 800 and 400 BCE. The Mahabharata and Bhagavad-Gita are other best-known book and widely cited on Hinduism. The Ramayana is the other most important epic book on Hinduism which teaches about life, principles, duty, justice etc. through the life-story of Rama.

Dasharatha was a great Hindu king of the Kosala kingdom and Ayodhya was the capital from where He ruled. He was the son of King Aja of Kosala and Queen Indumati of Vidarbha. Dasharatha had three primary queens namely - Kausalya, Sumitra, and Kaikeyi. Unfortunately, the King had no sons to continue his dynasty after him. Despaired Dasharatha summoned Rishyashringa, a forest rishi for a ritual to fulfill his desire of have sons. By that way, the King had four sons. Queen Kaushalya gave birth Rama and similarly, Kaikeyi gave birth Bharata and Sumitra gave birth two sons, namely - Lakshmana and Shatrughna. Lakshmana was very much attached and devoted to Rama while Shatrughna was devoted to Bharata.

Abstract

The rhizomicrobiome plays a vital role in maintaining plant health and is highly influenced by the root exudates of the host plant. Plants select a subset of microbes at different stages of their development, and determine the microbiome community composition in its immediate vicinity presumably for specific functions. The rhizomicrobiome is composed of diversified microbial community with specific functions and is highly influenced by the plant type, soil type and environmental conditions. The rhizomicrobiome communities apart from promoting plant growth also elicit induced systemic tolerance to salinity and drought in stressed plants. Bacterial communities producing 1-aminocyclopropane-1-carboxylate (ACC) deaminase modulate stress ethylene in plants and alleviate the effects of abiotic stress and increases plant adaptability to stressed environment.

Introduction

Global warming needs a shift to automobile solutions that reduces/ do not produce greenhouse gas emissions. Automobile related pollution is the major source for reduction in air quality in Indian cities. India need to reduce dependency on a fossil- fuel and reduced transportation related emissions. People living in some of the Indian cities are being affected by noise pollution and electric vehicles may contribute to a reduction in noise pollution levels in the cities. Energy efficiency and emissions are two important contributing factors in transportation across the globe.

Introduction
The rapid advancement of information technology in recent years has led to an explosion in the awareness of environmental concerns and issues pertaining to human health. UNEP created UNEP net, the green global Internet, as well as the satellite communication system.
Information technology is necessary for environmental management.
The general population, especially in developing nations, and decision- and policymakers still have limited or no access to this information in a readily comprehensible format. Politicians and the general public have not yet been able to personally experience the effects of ozone layer depletion, climate change, or biodiversity loss. These are all new challenges, and scientists strongly advise taking more immediate action than legislators are able to. Thus, it is more crucial than ever to close the knowledge gap between scientists and decision-makers in order to formulate environmental policy.
UNEP created the Global Resource Information Database in 1985 in an effort to close this information gap and give the world’s population access to current, trustworthy environmental data. Telecommunications and geographic information technology were used as strategic tools to do this, with the former being used for information exchange and analysis and the latter for information distribution.

1. Introduction
The world’s ecosystem is facing significant challenges because of risingpopulations, more urbanization, and industrialization (Juwarkar et al.,2014). Significant environmental contamination has been caused by moderncivilizations, industrialization, population increase, intensive agriculturalpractices, human activities, and technological advancement (Lalevic et al.,2016).

1. Introduction
Oil spills are defined as the unintentional release of liquid petroleum hydrocarbons into the environment, predominantly impacting marine ecosystems. This form of pollution, often caused by human activities, can also occur onterrestrial landscapes. Spills typically result from the discharge of crude oilfrom sources such as tankers, offshore platforms, drilling rigs, and wells, aswell as from refined petroleum products like gasoline and diesel (Smith etal., 2019). While such incidents are primarily accidental, they may arise fromvarious circumstances, including inadequate storage or poor maintenance,leading tocontainerleaks. Historically, one of the earliest documented oil spillsoccurred in 1907 in Batum, a region then part of the Russian Empire (moderndayBatumi, Georgia). This incident, involving a collision between an oil-ladenship and another vessel in the Black Sea, marked the beginning of recorded oilspill events, though historical records from that time remain limited (Johnsonet al., 2021). The consequences of oil spills are profound, affecting both theenvironment and the economy. On the ocean’s surface, oil disrupts aquaticecosystems by blocking sunlight penetration and depleting dissolved oxygenlevels, which are vital for marine life. Crude oil compromises the insulating andwaterproofing properties of fur and feathers, leading to hypothermia and deathin oil-coated birds and marine mammals. Additionally, ingesting oil can causeseveretoxicity, while damage to habitats and reproductive systems often delaysthe long-term recovery of affected species. Coastal vegetation, particularly inecosystems such as saltwater marshes and mangroves, is also highly vulnerable

Introduction 
Fossil fuel consumption is associated with a number of grave problems, including economic distress and increased greenhouse gas emissions that cause global warming. The world’s population and environment are deeply concerned about these issues, which are a result of rising greenhouse gas emissions and the depletion of fossil fuels. Furthermore, there has been much discussion about the effects of relying so heavily on petroleum-derived fuels on the environment, the economy, and energy efficiency [1]. According, high process costs, inadequate infrastructure, and other technological challenges impede the manufacturing of second- and third-generation biofuels [2]. The main role of enzymes and other microorganisms during fermentation is as a catalyst to speed up the process of turning saccharides into alcohol. In this kind of biofuel production, lignocellulosic and algal material make up the majority of the biomass used to produce ethanol. The biochemical variety of microalgae is employed in numerous biotechnological and commercial applications [3]. The use of non-usable biomass has been enhanced with each new generation, which lowers production costs and speeds up the manufacture of biofuels. A wide variety of biofuels, such as biogas, bioethanol, biohydrogen, and biodiesel, can now be produced thanks to the application of nanotechnology. In order to convert triglycerides into biofuels, two important chemical events must occur: trans-esterification and esterification [4]. The majority of the nano-catalysts needed to produce biofuel come from microbial fuel cells. Nanoparticles, nanosheets, and nanotubes are examples of these nanocatalysts [5]. The utilization of nanotechnology in the biofuel production process holds promise for enhancing the effectiveness of current procedures. Compared to the production of biofuels, the synthesis of nanoparticles is much more interesting due to the potential applications, challenges, and opportunities that it presents [6]. Here, we review the literature on the application of nanotechnology to improve bioenergy production from algae processing. The different kinds of nanoparticles, including metallic, magnetic, metal oxide-based, and carbon nanotubes that are utilised in the production of bioethanol and biodiesel are covered on this page. A focus is placed on the application of these nanomaterials and how they affect the extraction and transesterification of lipids [7]. This chapter makes the connection between the advancement of nanotechnology and its contribution to the creation of a more efficient and sustainable technique for processing algal biomass to produce bioenergy.

Introduction 
The demand for alternative energy sources is on the rise as a result of global apprehensions regarding the swift exhaustion of fossil fuels, escalating energy usage, and significant environmental challenges (Lijó et al. 2019). Microalgae are regarded as highly favorable raw materials for upcoming energy sources, thanks to their various advantages, including rapid growth rates, elevated lipid contents and resistance to a variation of pH, temperature, light intensity, and salinity (Goswami et al. 2022; Zhang et al. 2022; Wang et al. 2019; Das et al. 2011). As per a recent evaluation of the lipid production efficiency of microalgae biomass, numerous nations could derive their transport fuel (~30%) from microalgae biomass grown on non-agricultural areas (Moody et al. 2014). Apart from their higher lipid production efficiency in contrast to earthly raw materials, microalgae consist of lipids, polysaccharides, pigments, proteins, and nucleic acids, making them versatile raw materials for a range of finalized outcomes, including nutrients, pharmaceuticals, biofuels, and bioplastics (Tang et al. 2020; Kim et al. 2016; Moody et al. 2014; Sharma et al. 2011). Additionally, microalgae are appealing for their efficient sequestration of CO2 during photosynthetic growth (Vargas-Estrada et al. 2020). In contrast to landbased oilseeds, microalgae can be cultivated in freshwater and contaminated or saline locations, eliminating the requirement for substantial nitrogen fertilizer application (Sharma et al. 2022; Rashid et al. 2019; Lam and Lee 2012). The positive attributes of microalgae as raw materials have prompted substantial research endeavours aimed at the commercialization of microalgal biofuels. Regrettably, microalgal biorefineries continue to encounter various technological and economic challenges (Khoo et al. 2020). In essence, nanotechnology involves the invention, creation, and utilization of resources at the nanoscale. Precisely, nanomaterials engineering explores the synthesis and designing of artificial or adorned nanoparticles to drive technological progress and enable applications that would otherwise be impractical. Nanomaterials possess surface areas hundreds of times greater than their weights, significantly enhancing their physico-chemical attributes (Husen and Siddiqi 2014; López-Serrano et al. 2014). Currently, nanotechnology-driven developments, with diverse potential features, have emerged as a burgeoning trend in various industries, including drug delivery, food industry, catalysis, coatings, agriculture, bioremediation, cosmetics, and materials science (Malik et al. 2023). Nanoparticle engineering offers practical and potential solutions to address the problems that arise at different phases of the microalgal biorefinery procedure. For instance, diverse nanomaterials have been proposed as ways to enhance transformation efficacy and the quality of green diesel. The distinctive capabilities of nanoscience and nanomaterial engineering exert a substantial impact on the commercial feasibility of microalgae derived products, including bioactive compounds, oils, lipids, and biofuels (Kumar et al. 2020; Milano et al. 2016). Nanoparticles have the capacity to boost intracellular fatty acid synthesis and complete microalgal biomass, leading to substantial reductions in production expenses. The presence of nanomaterials enhances the efficiency and speed of the microalgae harvesting, and the recoverability and reusability of these materials contribute to improved production efficiency.
