Introduction

The development of any region is reflected in its quantum of energy consumption. With a view to keeping the pace we have to grow our energy resources at a rate that commensurate to sustainable development. There is already shortage of electricity, reflected in power cuts notwithstanding enhancement of electricity production of several folds in the country. The problem is more severe in context with rural areas in India where some 70% of population live and have agriculture as the main occupation. Although statistically few thousand villages are yet to be electrified, the availability of regular supply in far off places has been a problem and the farmers are unable to derive benefits of electricity. The fast depleting kerosene is used for lighting and diesel oil for running agricultural machinery including pumps. In addition people burn firewood, agricultural waste and cow dung cake for cooking food causing irreparable damage to the ecosystem. According to Lester Brown there will be plenty of food to eat but no fuel to cook. The burning of cow dung deprives farmers the use of potential source of organic manure. Further, due to shortage of energy resources, farmers are unable to process the agricultural products to enable them to accrue more benefits. The situation is still worse in arid region where bio mass is scarce and there is no hydro electricity. In addition, farmers are unable to generate additional income due to lack of energy resources to run appropriate device in cottage industries. In this context, solar energy utilization has a tremendous potential for providing needful energy to the farmers for domestic, agricultural and allied applications leading to a sustainable development.

1. Introduction
Early childhood (0-6 years) is the most important period in a child’s life; it is during this period that the foundations for the child’s cognitive, social, emotional, physical and mental development are laid. As a result, the Ministry of Women and Child Development implemented several programs aimed at the welfare, development and protection of children and pregnant women. One such program is The Integrated Child Development Services (ICDS) program, which began on October 2, 1975. In India, ICDS is the most important government intervention for reducing maternal and child malnutrition and it has grown to become the world’s largest program of its kind. The ICDS aims to provide an integrated package of early childhood services in order to lay a solid foundation for the development of the nation’s human resources. The ICDS scheme is intended to be both preventive and developmental in nature. ICDS gives hope to millions of vulnerable women and children by assisting and supporting them during times of food insecurity and rapid growth. Because of its nationwide coverage, this program has all of the necessary structures in place and provides nutritional safety for the most vulnerable and poorest of the poor. This is a one-of-a-kind program with no counterpart anywhere in the world, in terms of scope and coverage.
Objectives of the ICDS Program
The following are the objectives of the ICDS scheme:
1. To improve the nutritional and health status of children in the age group of 0-6 years
2. To lay the foundations for the proper psychological physical and social development of the child
3. To reduce mortality morbidity, malnutrition and school dropout
4. To achieve an effective coordination of policy and implementation among the various departments working for the promotion of child development
5. To enhance the capability of the mother and the nutritional needs of the child through proper nutrition and health education.

Introduction 
Sustainable development is one of the most important concepts in a business organization. In order to satisfy all the needs of the present without compromising the ability of future generations to meet their own requirements, sustainable development is a comprehensive strategy to growth. In order to build a stable and equitable future, it incorporates social inclusion, economic progress, and environmental conservation. The “three pillars” or “three dimensions” of sustainability—economic, social, and environmental—are frequently used to frame the idea of sustainable development. The North East Indian state of Assam’s cultural and economical legacy has an intricate connection to the long and prosperous past of the Assam Silk Industry. From the very ancient times, the production of silk from silkworm and weaving into beautiful garments can be seen in this part of the region.Evidence indicates that the cultivation of silk and weaving were well established in the region by the first millennium BCE, incorporating thousands of years to the cultural heritage of silk weaving in Assam.The indigenous communities of Assam, particularly the Bodo-Kacharis, have been identified for spreading sericulture to the area. Assam produces three types of silk, namely Muga Silk which is also termed as Golden Muga, Pat Silk and Eri or Endi Silk. Also known as the “Golden Silk”, Muga Silk is unique only to Assam and hugely popular because of its natural sheen which increases with each wash. The silk is produced by a special silkworm Antheraea assamensiswhich is endemic to Assam. The town of Sualkuchi, in the Kamrup district of Assam, India, is home to the well-known traditional silk-weaving industry. Sualkuchi, dubbed the “Manchester of Assam,” is well-known for its superior silk goods, especially those crafted from Assamese-only Muga, Eri, and Pat silk(Ghosh, 2021; (Rajesh et al., 2020) The Assam Silk is considered as one of the finest in regional, national and international market because of its superior quality, bright colors and attractive designs. It has a good amount of potential to boost the economic development of Assam. Despite having such importance, it has been observed that the silk industry is facing a lot of problems which is causing a major setback in its growth. The Silk Industry of Assam is highly unorganized because there are less or no educated laborers which results in shortage of agricultural laborers ultimately leading to production shortage. The Assam silk industry, known for producing exquisite silk varieties like Muga, Eri, and Pat silk, faces several marketing challenges that hinder its growth and global competitiveness. Despite being geographically unique particularly Muga Silk, its brand identity is not widely recognized in outside the market. Its reach is restricted to premium and high-end fashion markets due to this lack of worldwide awareness. The majority of Assam’s silk output is limited to local and regional markets. The industry’s minimal web presence and inadequate marketing infrastructure make it difficult for it to penetrate larger domestic and international markets. Silk from Assam is not sufficiently promoted in international forums. There are government initiatives; however, there is a lack of consistency and broad audience reach in marketing activities. In marketplaces where there is competition, this causes the silk to be less visible.Producing Assam silk, particularly Muga silk, requires a lot of work and money. The final product’s high cost of manufacture restricts its customer base to a premium market niche. This lowers total sales and narrows the target market.

2.1 Overview of the CDM Project Cycle

The ultimate governing body of the CDM is the Conference of the Parties/Meeting of the Parties to the Kyoto Protocol (COP/MOP). The COP/MOP is the annual meeting of the signatories to the Kyoto Protocol and is responsible for managing the CDM Executive Board and for overseeing its work. The Executive Board supervises the CDM process under the authority and guidance of the COP/MOP; it is fully accountable to the COP/MOP. The Board decides on rules for the implementation of the CDM, as well as making the final decisions about acceptance of methodologies, registration of projects and issuance of CERs. The Board is composed of 10 members and 10 alternates. The CDM Executive Board created an A/R Working Group to specifically oversee LULUCF under the CDM. The A/R Working Group provides guidance to LULUCF project developers and, using expert reviewers, makes recommendations on acceptance or rejection of LULUCF methodologies.

Introduction

The Himalayan Moutains that is relatively a younger formation and geologically a very complex occupies most of the Arunachal Pradesh. The mountain terrain covers an area of about 86000 sq. km with elevation ranging from 400 to 6000 m above mean sea level (Satapathy and Dutta 1999). The wet tropical and sub-tropical climate which prevails in most part of the Arunachal Pradesh, there is usual phenomenon of erosion and land degradation by the action of water. It is estimated by the application of USLE for Arunachal Pradesh that the total amount of about 669.35 million tones of soil is eroded annually with an average rate of 90.7 tonnes /ha/year (Singh, 1999).

Arunachal Pradesh falls under upper Brahamaputra river system constituted by 10 major river basins. They are Tawang, Kameng, Dikrong, Subansiri, Siang, Sesseri, Dibang-Tellu, and Tirap-Tiso. In Arunachal Pradesh, Dikrong river is named after joining of two main rivers Pachin and Para . In the catchments of Dikrong river light textured unstable soils with the prevalent practice of Jhum Cultivation makes the entire catchments susceptible to erosion. In every monsoon the river Dilrong carries tremendous amount of silt, gravel, small boulder and causes flood in some parts of the catchments susceptible to erosion. Singh (1999) observed that loss rate through Dikrong River was 100.98 tones/ha/year. This indicates serious threat to soil resources and there is need for urgent treatment for sediment control in Dikrong river bash.

The acts for Environment Protection are :

The Environment (Protection) Act
In 1986, the Environment (Protection) Act was introduced. Concern over the environment’s declining condition grew, leading to the passage of this act to safeguard it. The goal is to plan, organize, and carry out the long-term requirements for environmental safety as well as to oversee and coordinate the development of an effective system for responding to environmental emergencies.
If we want to protect our environment, we must move far more quickly to execute this legislation. Food cycles are disrupted and species are lost when dangerous substancesare present in the atmosphere and aquatic environments in excess.
The Environment Act of 1986 has a Global Context in Addition to Aignificant Constitutional Ramifications.
• This act put into practice the spirit of declaration approved by the United Nations Conference on Human Environment, held in Stockholm in June 1972.
• In the 1970s, environmental protection gained national priority because to the significant growth in damages.
• Food chains are disrupted and species are lost when there are excessive quantities of dangerous substances in the atmosphere and aquatic habitats.
• Goals
• Clearly defining what environmental conservation is.
• Determining the generally acknowledged regions that pose a threat to the life support system.

Additive manufacturing is increasingly important for developing resource-efficient and customized products while reducing material waste associated with conventional manufacturing. This chapter examines the role of additive manufacturing in supporting green and sustainable production systems. It covers environmental benefits, economic and operational advantages, additive manufacturing technologies, sustainable applications, life-cycle assessment, environmental impact analysis, challenges, and design strategies. Industry trends, case studies, sustainability standards, and future research directions are also considered. In the context of green composites, additive manufacturing can support flexible fabrication and potentially improve material utilization and product customization. The chapter emphasizes the need to evaluate manufacturing technologies across their complete environmental and economic life cycle.

Biofuel crops play a crucial role in the global transition towards renewable energy. With increasing concerns about climate change and energy security, biofuels have emerged as a viable alternative to fossil fuels. However, their economic viability is influenced by various factors, including production costs, market demand, government policies, and environmental implications. The United States has been the most prominent fuel ethanol producer since 2007, followed by Brazil. Together the United States and Brazil account for 84% of the global ethanol production. European Union, China and Canada are the other leading fuel ethanol producers. Fuel ethanol production and consumption continue to rise, regardless of variations in crude oil prices. The United States is the largest producer, generating 60 billion liters primarily from corn, while Brazil follows with 33 billion liters, mainly derived from sugarcane (https://www.statista.com.) Ethanol production in India started in 1938 with recommendations to convert molasses into alcohol, eventually resulting in the enactment of the Power Alcohol Act in 1948. The Ethanol Blending Programme (EBP), introduced in 2003, mandated a 5% ethanol blend (E5). However, due to supply shortages in 2004-2005, the blending requirement was made optional. In the 2013-14 period, a total of 38 crore liters of ethanol was procured for blending with petrol. This amount significantly increased to 567 crore liters in the Ethanol Supply Year (ESY) 2022-23, achieving an ethanol blend level of E11.7. Acknowledging the substantial progress in the ethanol fuel blending initiative for a greener transition and Atmanirbhar Bharat, the government revised the target to E20 by 2025–26 and set an E30 goal for 2030 (NAAS, 2024). The proposed share of E20 is from sugarcane-based ethanol 10%, maize 7% and other damaged food grains 3.0%. The recently reported data during Jan 2025 showed the achievement of 19.6% blending in petrol (PIB, GOI, 2025)

Introduction 
Fossils fuel resources are crucial for producing and distributing other goods, making them one of the most important global commodities. Fossil fuels account for more than 75% of total energy consumption in society. It is critical to recognize that the fossil energy problem and anthropogenic climate change problem are inextricably linked and must be addressed as two intertwined challenges requiring a comprehensive solution. The features of coal, oil and gas which are employed as fossil fuels for power generation, have different classification of characteristics (Shindell & Smith, 2019). Fossil fuels are natural fuels and derived from the decompositions, heating and pressurization, of buries phytoplankton (plants) and zooplankton (animals). Over time, these waste materials get decomposed to produce carbon rich deposits that are now used to create energy products (Holechek et al., 2022). They are essential for the synthesis of steel and polymers in addition to energy. Fossil fuels fall into three main categories: coal, oil, and natural gas (Singh et al., 2023). Biofuels are produced from plants and animals waste materials and considered as a renewable source of energy. The sources are key components to overcome the issues related to greenhouse gas emission. Due to rapid change in climatic conditions, demand of renewable energy sources has increased. There are some drawbacks for fossil fuels due to presence of high carbon footprints and environmental impacts. On the other way, biofuels offer two major benefits first they reduce carbon emissions and modify waste management method, the other paving the way for a sustainable future. The carbon neutrality of biofuels is among their most alluring features. Biofuels only release the carbon dioxide that plants consume during growth, as opposed to fossil fuels that release old, stored carbon into the atmosphere. They are an eco-friendly choice because of this balance(Jeswani et al., 2020). Bioethanol, biodiesel, and biogas are among the several types of biofuels(Esmaeili & Tamjidi, 2021). Bioethanol is used in transportation and produced by using crops like corn and sugarcane. Waste management and sustainable energy production are further enhanced by biogas after producing with the help of anaerobic digestion of organic waste and is a great source of energy for heating and power generation. We can take a comprehensive approach to sustainability, improving energy efficiency and lessening our environmental impact, by combining the production of biofuel with waste management and the use of organic fertilizers. Significance environmental benefits of biofuels include lower GHG emission, reduced dependency on the fossil fuels and better air quality. By diversifying energy sources and possibly stabilizing prices, they also lessen exposure to changes in the world's oil markets, which promotes energy security. Nonetheless, it is essential to evaluate the wider ramifications of biofuel production and make sure that its advantages exceed any potential disadvantages in order to completely match with sustainability goals(Jeswani et al., 2020).

Introduction

Solar energy could be converted to electricity both through thermal route and photovoltaic cells but the latter is more advantageous as it has no moving part, it doesn’t require water, a rare commodity specifically in arid regions. Moreover, the maintenance of PV systems is easy, it can be installed right at the place of utility, the system is modular and these are reliable having life more than twenty years and of course eco-friendly.

In photovoltaic cells, generally known as solar cells, charge carriers are generated by the incoming irradiance (energy greater than band gap) and these are separated and swept away by an internal electric field, which is created by either making metal semiconductors contact (Schottky barrier) or p-n junction or MIS (Metal Insulator Semiconductor) or SIS (Semiconductor Insulator Semiconductor) devices. The height of potential barrier at the junction determines the voltage and the flowing charge carriers contribute to the current when connected externally. The choice of material depends on its band gap, absorption coefficient, diffusion length, mobility of charge carriers, ease in contact formation, type of junction with thermal and electronic compatibility, availability of material, toxicity and several other fabricational opto-electronic and practical aspects. PV cells based on single crystal and polycrystalline silicon, amorphous silicon, CdS, CdTe, CuInGaSe, InP, GaAs etc. have been much studied. PV modules of efficiency above 16% on silicon and 10% on CdTe, CuInGaSe and 8-9 % on amorphous silicon are commercially available. Dye sensitized TiO₂ devices have also been receiving more attention with coloured panels for windows. Organic semiconductors are explored and more recently perovskite solar cell has been studied. Flexible solar cell panels based on thin film devices are in use. The applications have gone from solar lighting to operation of pumps, small and medium size equipment, stand alone and grid connected solar power plants, roof top and building integrated PV and now even energizing cars and aero planes. With technological advancement and enhanced production (233 GW in 2015) the cost of commercially available PV modules, which used to be high at one time has been brought down from 30 $/Wp in seventies to about $0.5/Wp at present.

The recent earthquake in Nepal brings back memories of 26th January 2001. While the nation was busy in celebrating Republic Day, an earthquake shattered Gujarat especially Kutch and Saurashtra regions. A large number of buildings and houses collapsed within moments. Thousands were injured and many lost their lives and many more became homeless.

Kutch received quick responses from all over the world and a large number of individuals, institutions, government and semi-government bodies, professional experts, religious and social organizations etc. sprang into action to bring back some normalcy in the lives. However, long-term rehabilitation program based on scientific planning is most vital after such disasters.

Introduction 
The evolution of health care since 1950s has been attributed to artificial intelligence (AI). Remarkable advances in the health sector are being made particularly after the years, following 2010, thanks to AI technology. The significance of AI as a game-changer in healthcare has tremendously grown together, with its accompanying range of challenges, opportunities, and reward. There is increasing utilization of AI across public health activities including biomedical research with its capacityto reduce medical errors and improveaccess to care. The efficiency and ability of AI to analyse large volumes of data in different medical fields so as to identify diseases and guide treatment plans has turned it into an area of significant impact in clinical decision-making. Machine learning as well as data analytics are examples of AI technologies employed in monitoring, diagnosis, treatment and measurement of risks/benefits thereby transforming various healthcare processes. It is revolutionizing medical practices in several areas such as diagnosis, treatment, rehabilitation and surgical operations [Tagliaferri et al., 2020]. Studies have found that, the use of AI has improved patient outcomes and simplified management duties, resulting to an efficient health service delivery system. As the influence of AI continues to grow, understanding its implications, benefits, and challenges becomes essential for healthcare professionals and policymakers alike.

Selection is an important activity in all the breeding programmes. Different types of selections i.e. mass selection, progeny selection and cyclic selection etc. are used depending on the mode of pollination of the crop species, the predominant gene action and the breeding objectives. The efficiency of selection largely depends on the extent of genetic variability present in the population and the heritability of the character. Selection is more effective for character with high heritability than those having low heritability. Breeding for higher or better yield is the breeding objective for most of the breeding programmes, but it has low heritability. Yield is considered to be complex or super character which is influenced by many components or contributing traits both in positive and in negative directions. Due to the fact that it has low heritability, selection is done for the yield contributing traits so that yield may be increased through selection. Prior to selection for yield contributing traits, it is always beneficial to study the extent and type of relationship between the character and yield. There are different procedures which aid in the isolation of superior yielding genotypes from genetically variable populations by providing information on indirect selection for yield. These methods are discussed in the following content.

Air or atmosphere constitutes one of the integral components of the environment. Among all the environmental components, the air has the highest fluidity. Therefore, the entry of a foreign substance into the air imparts a quick and severe effect on the health of the organisms. Air in the biosphere has a mixture of various gases in a dynamic proportion which is conducive to maintaining the health and sustenance of all living organisms. An alteration in the composition of the atmosphere beyond a certain limit adversely affects organisms’ health, and might even be of more serious consequences for life.

Air pollution, thus, is defined as the occurrence of undesirable gases (e.g., carbon monoxide, sulfur dioxide, etc.) or particles (e.g., suspended particulate matter) in such concentrations that are deleterious to terrestrial life (vegetation, animals, and human beings) and some physical assets, like buildings, statues, and monuments. Air pollution especially affects the health of human beings living in highly modified (anthropogenic) ecosystems, e.g., cities and industrial areas.

Air is one of the most important constituents of man’s environment. It is calculated that a roan breathes about 22,000 times a day inhaling about 16 kg of air by weight. Air is present everywhere and its entrance from one place to another cannot be checked. Clean and pure air is very essential for the health and survival of man.

Introduction 
The increase in the concern over the climatic changes as well as the dwindling fossil fuels reserves have intensified the search for the sustainable energy sources. The algal biofuels garnered the attention because of their fastest growth rates, as well as their capability to grow in a non-arable land, higher lipid content, as well as the capability to absorb the CO2. Therefore, the larger scale implementation of the algal biofuels can face a lot of environmental, economic, as well as the technological challenges which needs further investigations (1). One of the current green energy and renewable alternative answers to the world’s current energy problems is the development of algal biofuel (2). Because algae biofuels are environmentally beneficial, they have been seen as a clean energy source (3). An integrated biorefinery strategy could be applied to bio transform algal biomass into many biofuels, including bioethanol, biobutanol, biogas, biohydrogen, and biodiesel, in order to fulfil the energy requirement. Nonetheless, a lot of an obstacles stand in the way of the development, manufacturing, as well as use of microalgal biomass technology. (4). These problems include the creation of affordable microalgal production systems, efficient microalgal growth systems, effective microalgal harvesting techniques that save energy, effective microalgal extraction methods, and economical and environmentally friendly microalgal conversion procedures. Many microalgal technologies are examined in this chapter, along with their applications, difficulties, case studies, and prospects. (5). Algae are appealing feedstock sources for the manufacturing of biofuels. Algae may be applicable to produce important goods like as nutraceuticals, biodiesel, biogas, as well as bioethanol (6). Biofuels are benign to the environment, renewable, and biodegradable. Algae are very valuable because of their higher lipid content as well as fast development. The largest class of algae, known as chlorophytes, includes both macro- and microalgae and is used in bioremediation, the water treatment, the food production, the medicine, as well as the energy production. We discussed many techniques for planting, harvesting, and processing in this chapter. The selection of high lipidcontaining algae strains, commercial harvesting, high infrastructure, operation, and maintenance expenses, and water evaporation problems seem to be the main obstacles. It will take creative and effective methods to make the manufacturing of algae-based biofuels desirable. Increasing the production of biofuels will contribute to the preservation of natural resources, which will protect the environment (7).

1. Introduction
Metals pollution in water particularly in wastewater has become a center ofconcern due to social changes such as industrialization and urban development(Blaszczak-Boxe et al., 2023). It is in this context that most of the conventionalwastewater treatment fails to remove the heavy metals in question satisfactorilyand that there is a pressing need for new ideas that would be sustainable. Thischapter aims to discuss algal bioremediation as an environmentally suitableprocess for the decontamination of wastewater containing toxic metals.

8. Introduction

The idea of sustainable development stands on the concept of maintaining the best possible environment within the availability of minimal resources and for the convenience of the society. Now-a-day the term “sustainability” gained a lot of attention due to challenges and problems faced in tackling the current situation of global pollution. One of the vital areas of research needs to be addressed in concern with sustainable development is the new innovations to enhance sustainability (Silvestre and Silva, 2014).
