Introduction 
Inclusive education means including all children in the same classrooms, in the same schools. It means real learning opportunities for groups who have traditionally been excluded – not only children with disabilities, but speakers of minority languages too. The school and classroom operate on the premise that students with disabilities are as fundamentally competent as students without disabilities. Therefore, all students can be full participants in their classrooms, in the local school community and in the societies they live in. Much of the movement is related to legislation that students receive their education in the least restrictive environment (LRE). This means they are with their peers without disabilities to the maximum degree possible, with general education the placement of first choice for all students (Alquraini & Gut, 2012). Inclusive education in India has evolved significantly over time. Initially, education for children with disabilities was largely segregated, with specialized institutions being the primary option. The shift towards inclusion began gaining momentum in the late 20th century, influenced by global movements and national policies. Key milestones include the 1992 National Policy on Education, which emphasized inclusive practices, and the 2009 Right to Education Act, which mandated free and compulsory education for all children, including those with disabilities. Recent initiatives have focused on improving accessibility, teacher training and integrating students with diverse needs into mainstream classrooms, reflecting a growing commitment to equitable educational opportunities for all. Contemporary inclusive education in India is characterized by a growing commitment to integrating students with diverse needs into mainstream schools, supported by various policies and initiatives. The 2016 Rights of Persons with Disabilities Act and the 2020 National Education Policy underscore the importance of inclusive practices, advocating for accessible infrastructure, specialized training for educators, and individualized support for students. Despite these advancements, challenges remain, including inadequate resources, a shortage of trained teachers, and varying levels of implementation across different regions. Efforts are ongoing to address these issues, aiming to create an educational environment where all students, regardless of their abilities, have the opportunity to succeed and thrive. The emerging importance of an inclusive education system in India reflects a growing recognition of diversity and equality in the educational landscape. This shift is driven by the realization that inclusive education not only promotes social justice but also enhances academic and social outcomes for all students. As India progresses towards a more inclusive society, there is increasing emphasis on

Introduction

The sun is an abundant source of solar energy (average value on horizontal surface 6 kW m^-2 day^-1), which is freely available. This huge source of energy is non-polluting and inexhaustible in nature. It has the potential of supplementing the conventional energy sources to a great extent. There is acute shortage of conventional energy sources, which affects the overall development. Work on the utilization of such a huge, non-polluting and everlasting energy source has been carried out at CAZRI, Jodhpur for various domestic, industrial and agricultural applications in order to supplement the energy demand. This includes the development of a lot of solar thermal devices, such as, solar still, solar dryer, solar cooker, animal feed solar cooker, solar candle device and cool chamber. The details of some of these devices are given as following.

Abstract

A majority of the plants studied in natural ecosystems are symbiotic with microorganisms that either reside entirely (endophytes) or partially within plants. These microorganisms express different associations ranging from mutualism to parasitism. These symbiotic relationships appear to impart tolerance to various types of abiotic stresses such as heat, drought, salinity, heavy metals, etc. and sometimes may be responsible for the survival of both plant hosts and microbial symbionts in high stress habitats. The amelioration of the abiotic stresses by the endophytes assumes increasing significance in the light of rapidly changing global climate, which is likely to face frequent incidences of extreme weather conditions like high temperature, droughts, etc.

Introduction

Natural Disasters are inevitable, and Indian subcontinent is prone to all type of Natural Disaster either it is flood, drought, cyclone, earthquakes, tsunami or forest fires etc. Disasters can be classified in several ways. A possible sub-division of disaster is: (i) Natural Disasters; (ii) Human made disasters; (iii) Human induced disasters. Another sub-division is related to the main controlling factors leading to a disaster. These may be meteorological, geomorphological/geological, ecological, technological, global environmental and extra terrestrial. Another useful distinction that can be made between disasters is regarding their duration of impact and the time of forewarning. Some disaster strikes within a short period with devastating outcomes; others have a slow onset period with equally or more serious repercussions. According to the available statistics 60% of the total area of Indian subcontinent is venerable to seismic activity of varying intensities, 16% of the country’s total area is drought prone. In India 68% of total sown area of the country is drought prone. Coastal areas of India is exposed to tropical cyclones, tsunami in recent years and among all the disaster occur in the country, River floods are the most frequent and often the most devastating.

Introduction

Cultivation of crops in greenhouse or protected structure has been increased tremendously in recent times and also has been spread from temperate regions to the warmer regions of tropics and subtropics. Plentiful technologies have been developed for heating the inside environment of greenhouse for optimum plant growth (Sethi et al. 2013). However, in hot arid areas, cultivation in greenhouse is very difficult as the temperature reaches to a very high level to sustain plant growth (Pek and Hayles 2004, Saran et al. 2010). Under such situation requirement for cooling the greenhouse microclimate environment is the necessity, but is very energy and water intensive. Hence, in such regions, reduction of air temperature inside the greenhouse or the regulation of temperature closer to the ambient temperature during summer is necessary for successful crop production. A typical diurnal variation of temperature and global solar radiation during late winter months inside a shade net structure has been plotted in Fig. 18.1. It has been found that global solar radiation has been decreased to almost 1/3 of the radiation received outside by using 75% shade net cover. The temperature inside structure during morning time has also been found higher than outside temperature and in summer such increase is expected to be much higher.

Therefore, cooling is considered as the basic necessity for greenhouse crop production in tropical and subtropical regions to overcome the problems of high temperatures during summer months. Development of suitable cooling system that provides congenial microclimate for crop growth is a difficult task as the design is closely related to the local environmental conditions. Different cooling techniques for greenhouse crop cultivation may be found in Kumar et al. (2009). Fan pad cooling system has been widely used for greenhouse cultivation however, requires large amount of water during evaporation based cooling. Since water resources are becoming scarce in future such fan-pad cooling system may not be viable in future specifically in hot arid region.

The main objective of nanomedicine broadly defined as the comprehensive monitoring, repairing and improvement of all human biological systems, working from the molecular level using engineered devices and nanostructures to achieve medical benefit. Nanomedicine is the nanomachine of diagnosing, treating, and preventing disease and traumatic injury, relieving pain, and of preserving and improving human health, using molecular tools and molecular knowledge of the human body. Nanotechnology applications in medical science can be essential in achieving this goal. These applications involves extensive surveillance, control, creation, repair, and defence of all biological human systems, employing designed nanodevices and nanostructures which works in molecular level.

These three requirements are required to be followed in sequence for getting maximum benefits. However, integrated rural energy concept is a new area of work and not much experience is available in this field as compared to other rural development activities. It is difficult to give any guidelines for planning. One can only recommend approaches and not solutions to planning.

The rural area in developing countries are almost always rich in one or another sources of energy, which could be used separately or in combination with other sources in decentralized small scale units, or even on a household scale. Thus, the problem is one of good planning, management and a strong educational and promotions campaign, rather than the non availability of resources or the lack of technology. Further, after planning, prefect development of device and their effective operation is required.

The purpose of the Integrated Rural Energy Planning project should be clearly defined. It may design either for research and development or demonstration for Popularisation of system, education and training, promotion, health or combination of these.

It is usually better to start with a small size to gain experience and build up confidence before undertaking the large scale project. As defined earlier, one of primary requirement of Integrated Rural Energy Planning is to develop energy demand pattern, energy supply system and optimally match demand with supply.

Abstract

Contamination groundwater and soil due to heavy metals (HMs) has aggravated into a threat not only for people inhabiting the polluted areas but also for the vegetation of the region. Relying on the use of obligate symbionts, arbuscular mycorrhizal fungi (AMF) in remediation of contaminated sites can be a productive approach. These fungi due to high cation exchange capacity have the ability to adsorb heavy metals (HMs) on fungal tissues; they also possess enzymes responsible for reduction of metals to less toxic forms. In areas with high toxicity of various HMs such as lead, AMF extends its extraradical mycelium (ERM) beyond the depletion zone of plant roots increasing the availability of nutrients such as potassium, phosphorus, magnesium, and sulphur resulting in increased plant growth and yield. Production of phenol and organic acids by the fungus have been reported to increase iron diffusion, that is a co-factor for antioxidant enzyme superoxide dismutase. AMF sequester HMs in fungal structures and bind them in their chitin cell walls preventing their translocation to aerial plant parts.

Abstract

Soil salinization is an important factor limiting crop production, mainly in the arid and semiarid regions of the world. Nevertheless, plants naturally have evolved several physiological, biochemical and molecular mechanisms to establish and thrive in salt stressed soils. In addition to breeding crops for salt tolerance, recent emphasis is on exploring the possible role of plant-microbe interactions in amelioration of salt stress in plants. It is now well established that arbuscular mycorrhizal (AM) symbiosis alleviates the effect of salt stress in plants. Further, available evidence does suggest that AM symbiosis regulates many of the plant’s salt stress alleviation mechanisms. However, the molecular basis for many of these mechanisms is yet to be ascertained. In this chapter, we summarize the current knowledge on the role of AM symbiosis in alleviation of salt stress in crop plants, which now appears to be a promising strategy to improve crop yield in salt stressed soils.

Introduction 
In the past, literacy in reading, writing and mathematics was considered the basis of establishment in society. With this knowledge, anyone could run all the businesses of his professional life efficiently because no technical skills other than typewriter and general computer knowledge were required. In present set up, this general knowledge is no longer enough to perform any task smoothly today. In this age of science and technology, the old concept of literacy is no longer applicable. Three other types of literacy or skills have now been added to the past concept of literacy: information literacy, technological literacy and human literacy. In this age of technology, people cannot keep themselves functional in this digitized world by practical knowledge of analog equipment alone. In present days, people live and work on the constant flow of big data, connections, and instant information flowing from every click and touch of a device. Technology is not static. Evernew technological advancement brings tides of data before people, therefore, they need data literacy to read, analyze and use them. Technological literacy gives them grounding in coding and engineering principles, so they know how their machines tick. Ultimately, human literacy teaches them the humanities, communication and design, allowing them to work in human environments. Artificial intelligence (AI) is now a fact of everyday life in our modern hightech societies. There are many definitions of AI and each of those definitions has been revised over time. Presently, most definitions state that AI solves complex cognitive problems associated with human intelligence or that AI helps as many people as possible through smartphones or healthcare, or even that AI recognizes problems and creates solutions for the benefit of technology, people, and society. However, the core concept of AI has continuously been to create machines that were capable of thinking like humans. It took about 200,000 years for human intelligence to evolve from natural to artificial and only 10 years to cut ties with the Earth and move to the clouds. During the creation of AI, mankind learned a lot about what it means to be human, how human intelligence is structured, and how humans learn and acquire expertise. With more predictive power, more efficiency and the ability to deliver better results than humans, AI is rapidly moving aside from humans into the world of expertise. However, it is impossible to imagine that someone else will replace Homo sapiens at this moment, but its probability cannot be ruled out in the days to come. The day, when mankind, in the course of time, will immerse in the world of knowledge, robotics becomes an essential part of the human body and existence, the existence of mankind is sure to be threatened. In October 2017, Saudi Arabia granted citizenship to humanoid Sofia. Perhaps this is a new breed of human being brought about by technology in the 21st century. Just as the message of the first driverless car aroused a lot of curiosity among mankind and now that curiosity has disappeared completely, it is likely that the arrival of many Sophia’s will make the environment very normal in the coming days. So here comes AI – Artificial Intelligence, the driving force behind Sophia or Driverless cars. The very simple definition of artificial intelligence is -the intelligence displayed by machines. Today, in this age of science and technology, we can say that anything imaginable by humans can be done with the help of machines. Sundar Pichai, CEO Google and Alphabet in his article “The promise of AI for India and the World” opined that every technology shift is an opportunity to advance scientific discovery, accelerate human progress and improve lives. AI will do this on an unprecedented scale and India is uniquely positioned to play a leading role.

Introduction 
SDG 3 emphasizes good health and well-being for people globally. In this chapter, we will focuses on the health and well-being of the Indigenous Khasi Tribe living in Meghalaya, India. The Khasi Tribe comprises 7 sub-tribes, commonly known as ‘Seven Huts’ or ‘HynniewTrep, HyniewSkum’ in the Khasi language. The 7 sub tribes are Khynriam, Pnar, Bhoi, War, Maram, Lyngngam and Dikko. Although the culture, tradition, and beliefs are shared among all subtribes, earning them the common name Khasi Tribe, there are slight differences in terms of topography. Some sub-tribes live in sloping or steep mountainous areas, engaging primarily in forestry and horticulture, while others reside in plain areas, where they cultivate agricultural crops. As an indigenous group, the Khasi community follows certain beliefs and practices related to health and well-being. The Khasi tribe is a matrilineal society where women hold great responsibility at home and in the community. Some researchers have acknowledged that the Khasi tribe is one of the tribes in India with a better status in terms of literacy rates and nutritional status. (D Agrahar- Murugkar, 2004). Approximately 83% of the Khasi tribe are agrarian. The main food items that boost their immune system and make them strong and healthy include rice, dal, potato, tomato, bamboo shoot, pumpkin, green vegetables, citrus fruits, and meat (beef, pork, fish, eggs, and dry fish), which they cook in their own indigenous style. The majority of them are non-vegetarian. A common stimulant is betel nut, which has been used since ancient times as a social mediator to connect with others and form friendships. The Khasi people are hardworking; enjoy games and sports, and traditional music. In terms of social well-being, the Khasi tribe has a strong sense of “we feeling”, supporting one another, following ethical and moral instincts, and respecting one another. They believe in the spirits of Mother Nature (ki blei, ki basa). To maintain strong bonding and enhance Khasi Tribe sentiments, various festivals are celebrated every year, such as Shad Suk Mynsiem, Shad Nongkrem, Seng Kut Snem, Pom Blang, and Beh Diengkhlam. They also pay homage to freedom fighters who have died for the Khasi land, such as Tirot Sing, Kiang Nongbah, and Phan Nonglait. Following the legacy of these freedom fighters, various leaders are heading civil groups that monitor the performance of government administration and other welfare states for common social well-being.

Abstract

Climate change is the biggest problem of today, resulting in thawing glaciers, changes in crop yield, and disturbances of water resources not only in India but in the entire world. Crop yield were predicted according mid century (2050s) by using IPCC Scenario A2 and studied impact of climate change. Out of 80 districts of Uttar Pradesh the three were selected for the case study areas namely Meerut, Kanpur and Hamirpur. FAO based model ET₀ Calculator 3.1 and Aquacrop 3.1 Plus were used to estimate reference evapotranspiration and crop yields respectively by using two major food crops rice and wheat. Crop yield were estimated the present climatic conditions (2005) and mid-century condition (2050s). According to the comparison of simulation results for present and future scenarios, crop yield of rice and wheat was predicted to increase in the mid- century (2050s). However, food security was predicted to become a threat in future, because the increase in population till the 2050s is projected, and yield was increases in the major food crops. In order to sustain the growing population, there would be required in the future, a large area for growing rice and wheat in comparison to the area presently, to meet the same food availability per capita. Hence, there would be a need to increase the production of the food crops in order to meet the growing demands of food in the study areas.

Availability of genetic variability and exploitation of this variability are two basic requirements of successful crop breeding programmes. The presence of genetic variation in a character is a must for any improvement in that character. If all the individuals in a population are identical i.e. no variation is there, selection cannot be done, so no improvement will be done. In case of crops, if variation is not present or variation is very small, variations are created through hybridization, mutation, polyploidy etc. Selection is identification and isolation of desirable plants from a variable population. A population consists of large number of heterogenous individuals with different morphological expressions. This variability is contributed by three factors: 1. Genetic constitution of individual, 2. Environmental effect on the individual and 3. Interaction effect between gene and environment. These three factors contribute towards the phenotypic variability among the individuals of the population. Assessment of magnitude of variability present in a crop species is of utmost importance as it provides the evidence for effective selection. Phenotypic variation in a population arises due to genotypic and environmental effects.

The demand for lightweight, high-performance, and environmentally responsible materials is particularly strong in automotive, aerospace, and defence applications. This chapter examines biomass-derived green nanocomposites as potential materials for lightweight systems and energy-storage-related applications. It discusses material fundamentals, design requirements, sector-specific performance expectations, material systems, and performance benchmarks. Green processing and circular economy integration are considered alongside current technological challenges and strategic research gaps. Biomass-derived resources provide opportunities to reduce dependence on non-renewable feedstocks while developing functional composite materials. The chapter emphasizes the need to balance lightweight design, mechanical and functional performance, manufacturing feasibility, sustainability, and end-of-life considerations for demanding engineering applications.

Industrial revolution took place in England during the period of 1760-1830. Accordingly, the production prior to demand was introduced. Many countries all over the world adopted industrial policies favouring industrial sector to achieve the fast development of the nation. Government of India also contributed its efforts in the same direction and issued the industrial policy of 1948, 1956, 1977 and so on making several financial and non financial facilities available to have substantial growth and development of industries in particular and nation in general.

Under the name of globalization and making the economy internationally competent, India took a revolutionary decision to follow new industrial policy 1991 opening the doors for investment from foreign countries and private sector even. In addition to this economic reforms have been adopted and advocated for the sake of national development. Three ‘D’ programme consisting of devaluation, decontrol and disinvestment, were also put on the national agenda, to achieve the set targets.

Introduction

We are blessed with solar energy in abundance at no cost. The solar radiation incident on the surface of the earth can be conveniently utilized for the benefit of human society. Solar energy can be used as thermal energy for water heating, cooking, drying, distillation, space heating, cooling and power generation or it can be converted to electricity through photovoltaic cells, commonly known as solar cells. One of the popular devices that harness the solar energy is solar hot water system (SHWS). Flat plate collectors are used for low temperature applications (below 100^oC) while concentrators are preferred for higher temperatures. The most efficient application of flat plate collector is for getting hot water. Hot water in winter is an essential requirement for domestic uses such as bathing, cleaning of utensils and washing of clothes. In rural areas hot water is also required for softening of animal feed. Generally it is obtained by using firewood and cow dung cake in rural areas or using kerosene, liquid petroleum gas, coal or electricity in urban areas. Therefore, the use of solar water heaters will conserve lot of commercial and non-commercial fuels which are being wasted in merely getting hot water. A solar water heating system (SWHS) is made of several important elements: one or more solar collectors, a pump, a heat exchanger, a storage tank (or multiple tanks) and a back-up storage tank. The Solar heating system can be classified as passive or active. For water heating purposes, the general practice is to use flat plate solar energy collectors (FPC). The evacuated tube collectors (ETC) and evacuated tube heat pipe collectors (ETHP) are more efficient, though, the initial cost is comparatively higher. There are three type of water heaters extensively studied by various workers viz. natural circulation, collector-cum-storage and forced circulation in all over the world.

Introduction

Solar refrigeration technology engages a system where solar power is used for cooling purposes. It offers a wide variety of cooling techniques powered by solar collector-based thermally driven cycles and photovoltaic (PV)-based electrical cooling systems. Cooling can be achieved through four basic methods: solar PV cooling, solar thermal cooling, solar thermo-electrical cooling and solar thermo-mechanical cooling. The first is a PV-based solar energy system, where solar energy is converted into electrical energy and used for refrigeration much like conventional methods. The second method utilizes a solar thermal refrigeration system, where a solar collector directly heats the refrigerant through collector tubes instead of using solar electric power. The third one produce cool by thermoelectric processes. The fourth method converts the thermal energy to mechanical energy, which is utilized to produce the refrigeration effect.

The performance of solar refrigeration systems is determined based on energy indicators of these systems. The COP (coefficient of performance) can be calculated as follows:

Statistics involves procedures for collection, classification, analysis, interpretation and presentation of numerical data (Gupta, 1997). Statistical investigations involves four stages ie. collection of data, compilation of data, analysis of data and drawing inferences. For any statistical analysis, first step is data collection which constitutes the foundation for statistical analysis. The required data may be obtained either through survey or an experiment. Survey is the process of collecting data from a population but have no control over the factors which may affect the population characteristics under study, whereas in experiment, data is collected while control is exercised over the factors which may affect the population characteristics under study. Experiments always and almost provide better information than the survey but surveys are necessary in natural populations. When data is not available, it is collected by any of the two methods i.e. census or survey method. In census method, data are collected for each and every unit of the population whereas in sample method a representative sample is drawn from the population on the basis of which all the conclusions are drawn about the population from that sample.
