Introduction

Nanopesticides are pesticides that use nanomaterials or nanotechnology to improve their effectiveness and safety in agriculture. Nanomaterials are materials that have at least one dimension between 1 and 200 nm. Nanomaterials have different properties than their bulk counterparts, such as higher surface area, reactivity, and mobility. Nanopesticides can be formulated in various ways, such as nanosized active ingredients, molecular active ingredient nanocarrier complexes, or active ingredients encapsulated or coated by nanomaterials (Deka et al., 2021; Xu et al., 2022).

The hazardous toxic metals like cadmium (Cd), arsenic (As), mercury (Hg), lead (Pb), and chromium (Cr), which have detrimental health effects, are naturally discharged into the atmosphere in various ways viz., industrial wastes, anthropogenic sources, etc. Heavy metal pollution of the atmosphere has become a frightening ecological concern that has created serious threats to the ecosystem. These metals have been identified as group I, human carcinogens due to their persistence in the surroundings and bio-magnification in biological systems. Thus, the removal of heavy metals from the atmosphere becomes a serious matter from the biological and environmental point of view. In the past following techniques adoptedfor toxic heavy metals remediation were classified are bioadsorption, ion exchange, membrane filtration, flotation, and solvent extraction techniques.

Introduction 
Modern energy policies place a strong emphasis on developing low-carbon energy sources while also ensuring that society has enough energy security. However, because fossil fuels play such a vital part in the global energy system, measures to reduce GHG emissions from fossil fuels must be found. Researchers and scientists are examining the characteristics of materials at the nanoscale level to identify compounds that might boost the efficiency of the energy sources we now use. The physical properties of several materials (such as strength, heat conductivity, and reflectance) alter at the nanoscale in comparison to their bulk properties. When compared to their bulk properties, several materials have distinct physical properties at the nanoscale (such as strength, electrical and thermal conductivity, and reflectance). several materials on a nanoscale. Additionally, materials with nanostructures are more suited for material-to-material interactions due to their higher surface to unit weight volume ratio. This is a useful characteristic as many chemical and electrical reactions take place at surfaces and are greatly impacted by the chemical composition of the reactant and the surface’s structure. The goal of nanotechnology research in the fossil fuel industry is to create novel catalysts that will improve the energy efficiency of the fossil fuel breakdown process. Given that heavy crude oil contains sulphur. The transformation of coal into liquid fuels for use in transportation requires the employment of several kinds of catalysts. Furthermore, because of their structure and the presence of electrons in their outer orbitals, which increases the potential for chemical reactions, the majority of typical catalysts used in cars today rely on valuable metals like platinum. Concerns about the supply of precious metals are raised by the industrialised world’s transport networks’ explosive expansion. Finding more affordable and readily available substitutes is imperative given the scarcity and high cost of these materials, and this will be emphasised in the researchers’ upcoming work. Additionally, because of their unique qualities that relate to the phenomena of corrosion resistance or their exceptionally strong qualities that are advantageous in turbomachinery components, nanomaterials are also helpful in power systems (1) . The application of nanotechnology in the production of resistant ceramics for use as insulators in gearbox lines results in smooth coatings that reduce the likelihood of fouling in cooling water intakes. Additionally, nanotechnology can improve a material’s conductivity and produce a superconductor at ambient temperature rather than a superconducting characteristic at very high temperatures. Renewable energy sources—also known as “green energy”—such as solar, wind, and ocean energy— allow countries to reduce their reliance on petroleum and address environmental problems related to the use of fossil fuels. In these technologies, nanotechnology is also employed. Mao and Chen concentrated their research efforts on developing nanotechnologies for a select group of renewable energy sources, including fuel cells, solar cells, hydrogen storage, and hydrogen generation. This research aims to provide a comprehensive comparative analysis of nanotechnology’s application to the development of sustainable energy systems, including nanomaterials, nanofluids, and nanostructures.

Introduction 
The creation of molecular-scale machinery and gadgets at a few nanometers (10^-9 m), known as nanotechnology, has a substantial impact on this topic and dramatically reduces the size of a cell. To assess how nanoparticles affect the synthesis and production of biofuels, particularly biodiesels, a variety of nanomaterials, including nanofibers, nanotubes, and nanometals, are being used (1). Research on biodiesel has shown that utilizing nanotechnology and nanomaterials can be a useful approach to implementing low-cost techniques that improve manufacturing quality. Because of their tiny size and special qualities, such as a high surface area-to-volume ratio, catalytic activity, considerable crystallinity, adsorption capacity, and stability, nanoparticles (NPs) are useful in the generation of biodiesel (2). Because of their high potential recovery properties, metal oxide nanoparticles and carbon nanotubes are frequently used as nanocatalysts in the synthesis of biofuel and biodiesel (3, 4).This chapter critically evaluates the application of nanotechnology in the manufacturing and enhancement of biodiesel, addressing key challenges and potential advancements. Microalgae have been identified as a potentially useful feedstock for biodiesel production. The process of harvesting microalgae can be made much more efficient by employing a range of nanoparticles. Additionally, cost-cutting is facilitated by the recycling of nanomaterials and their incorporation into procedures including cell disruption, extraction, and harvesting. Furthermore, an array of nanocatalysts holds promise for enhancing the efficiency of biodiesel conversion (5). Classification of nanoparticles based on physical attributes as shown in (Fig.1). However, there is a growing emphasis on improving combustion efficiency and reducing harmful emissions in the engine industry and its associated fields. Several studies indicate that the introduction of nanoadditives into blends of diesel and biodiesel fuels has yielded significant results.

Nanotechnology has been successfully applied in various fields such as agriculture, biochemistry and medicine. However, its application in food systems has been new and is yet to be scrutinised. It offers a range of physical and chemical benefits that can be employed in production, development, fabrication, packaging, storage and food distribution systems. These novel nanomaterials such as nanocapsules, nanocomposites, nanoemulsions, nanoencapsulation, nano packaging, nanotubes and nanosensors have been used to improve food quality with better shelf life. However, there is concern about the safety of these nanomaterials, especially because of partial knowledge about the effects of these materials on human health.

Despite substantial advances in the diagnostics and treatment of diseases, parasitic infections are a major global health issue causing significant mortality and morbidity. Currently, chemotherapeutic antiprotozoal drugs, anthelmintic and anti-ectoparasitic agents are used to treat, but resistance to these drugs has developed due to overuse. In this scenario, nanoparticles are proving a major breakthrough in the treatment and control of parasitic diseases. In the last decade, there has been enormous development in the field of nano medicine for parasitic control. Gold and silver nanoparticles have shown promising results in the treatments of various types ofparasitic infections. These nanoparticles are synthesized through the use of various conventional and molecular technologies and have shown great efficacy. 

Agriculture serve as a backbone in improving economic growth of a country as well as it provides a base in meeting various needs of people in direct and indirect ways. The recent advancement in nanotechnology has shown a path to develop traditional agriculture into a sustainable practice. Several nanochemicals emerged as promising agents for better plant growth, used as fertilizer, pesticides, control weeds and also used as antimicrobial agents in food packaging. Nanotechnology may act as sensor for checking soil health of agriculture fields.

Nanotechnology epitomizes one of the most dynamic and transformative fields in modern science and technology. This multidisciplinary domain bridges chemistry, physics, biology, along with engineering, enabling the creation of materials and devices with extraordinary properties and applications. The book chapter reflects the research and patenting trends in nanotechnology. USA leading the global share for most patents granted followed by South Korea, Japan, China and Germany for the top five spots contributing more than 76% of all the granted patents by EPO & USPTO related to nanotechnology. Nanotechnological products in relation to sub-industrial areas of medicine, food, agriculture, cosmetics, environment, and renewable energies are also highlighted in chapter. 

Introduction
Education and Its Evolution
Education is a process of learning, which involves both formal and informal modes of learning, which transforms the behaviour, skills, knowledge attitudes, and beliefs of the learner. For this reason, it is more deliberate than other education activities since it is a deliberate effort to create learning in a bid to achieve set goals and objectives. Ordinarily, education is characterized by a systematic learning system that is complemented by curricula and instructional materials in different disciplines. This includes talking and explaining, discussing and questioning, performing and observing so as to reach individual students. Communication is also considered as necessary as education is a process of interconnecting people, exchanging information, and learning how to deal with society members. It also develops critical skills such as analysis and developing insights, due to its capacity to offer information to be analyzed, find solutions and then make sound decisions. Education implies character building and it shapes people into responsible members of society. Education also fosters a construct of perpetuity learning which in this case is strengths toward self and career. There is the principle of non-selectiveness as one of the basic principles of education, as education must be provided to all so that all students should be given an equal opportunity. Learners’ understanding and progress can be measured therefore, assessment and evaluation were part of the program to ensure that teaching strategies can be improved. In addition, it has a 96 | Sustainable Development Goals, Health & Education sociocultural function of passing on a culture from one generation to another, and thus preserving social and cultural development and growth. In its strictest sense education is learning as it is getting acquainted with information as well as has the added dimension of moulding positive character in the learners so that they and society can be the better for it. From antiquity to the present, education has undergone tremendous change, having a huge impact on the advancement of society. When education was first developed in ancient communities, it took the form of apprenticeships, oral traditions, and storytelling to impart cultural values, religious convictions, and useful survival skills. For the elite, it was frequently reserved, preventing access for the general public and preserving social hierarchies. A teacher-centered approach limited student interaction and critical thinking, and the curriculum prioritized memorization and rote learning with a focus on mythology and societal responsibilities. In comparison, the goal of contemporary education is to develop students’ ability to think critically, be creative, and solve problems in a formal, structured manner. Regardless of one’s background, access to it is considered a fundamental right that fosters inclusivity and social fairness. The curriculum’s diversity promotes inquiry and discovery by including technology, the arts, and the sciences. A variety of student-centered, modern teaching techniques are used to improve critical thinking and participation. Education is now a key factor in social and economic development as a result of this change, encouraging creativity and producing knowledgeable citizens who take an active role in solving global issues. After all, if education in the past served to uphold hierarchical institutions, education today aims to dismantle obstacles and promote equality in society.

INTRODUCTION

The discipline of Agrometeorology, an applied science is less than fifty years old. Its services are operationally used by individual farmers in developed countries, and by agricultural or development services in more than half of the countries of the world. Its contribution to agricultural production by examining forecast is sought in virtually all countries. In many countries, the respective governments have expressed the desire to use meteorological information to a much larger extent in day-to-day farm planning and operations. The climate database is used for the development of practical criteria in planning and management of irrigated and rainfed crop production system (Martin Smith, 2000).

Though a huge set of Agromet data exists in India, its utility has not been effective due to the scattered location of these data sources and the impediments for free flow of data to the users to analyze and interpret for real-time decision making in agriculture. There is also a considerable time lag between the actual observation and data availability. In view of the importance and the immediate exigency to centralize the database system for helping the researchers and planners, a central agrometeorological databank facility funded by DST from 1998 to 2003 and later by ICAR with the following objectives was established at Central Research Institute for Dryland Agriculture (ICAR), Hyderabad.

Definition of Disaster

A disaster can be defined as a sudden or catastrophic event that causes significant damage, destruction, and disruption to human life, property, or the environment. Disasters can be natural, such as earthquakes, hurricanes, floods, wildfires, or they can be human-made, including industrial accidents, terrorist attacks, or technological failures.

Disasters often result in the loss of lives, injuries, displacement of people, infrastructure damage, and the interruption of essential services like electricity, water, and communication systems. They can have long-lasting impacts on communities, economies, and the environment.

Governments, organizations, and communities implement disaster preparedness, response, and recovery strategies to mitigate the effects of disasters, protect lives and property, and facilitate the rebuilding and restoration of affected areas.

It is a well known fact that natural disasters strikes countries, both developed and developing, causing enormous destruction and creating human sufferings and producing negative impacts on national economies. Due to diverse geo-climatic conditions prevalent in different parts of the globe, different types of natural disasters like floods, droughts, earthquakes, cyclones, landslides, volcanoes, etc. strikes according to the vulnerability of the area. India is considered as the world’s most disaster prone country. It has witnessed devastating natural disasters in recent past like droughts, floods, cyclones, earthquakes, landslides, etc. 

Introduction

The natural hazards like floods, cyclones, droughts, landslides and earthquakes are not rare or unusual phenomenon. India is among the world’s most disaster prone areas and a large part of the country is exposed to such natural hazards, which often turn into disasters causing significant disruption of socio-economic life of communities leading to loss of life and property. It would not be considered as a disaster unless it resulted in actual damage to human life or property. According to data accumulated over past 25 years, natural disasters in Asia accounts for about 40% of the world’s total disasters while the death toll ratio is about 50% and the number of people affected is about 90%. The latter figure is about 2.2 times the ratio of number of occurrences in Asia. The figures vary widely over the decades, a result that can be attributed to a few particularly terrible disasters. Such as the 1976 Tangshan Earthquake in China, which killed about 250,000, and a series of severe cyclones that hit Bangladesh in 1970 with a death toll of about 500,000. The death toll resulting from wind and flood disasters jumped by an order of magnitude in the 1990s. But this sudden increase affected Asia’s ratio to the world total by about 15 percentage points because there was a worldwide surge in this type of disaster. Clearly, there is an extreme concentration of victims of such disasters in Asia, Another substantial increase is clear in the value of damage caused by typhoons and cyclones; it is now running at 10 times the level of the 1980s. Again, however, the ratio has remained almost unchanged, at about 40%, because hurricanes in Central and North America account for more than 50% of the world total (51.2%, 58.5%, and 54.4% in the 1970s, 1980s, and 1990s,respectively). It is sadly worth noting that there has been conspicuous growth in the absolute value of damage in both Asia and the Americas.

Introduction
A natural disaster refers to a significant and harmful occurrence caused by the Earth’s natural processes. Examples of natural disasters include floods, storms, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic phenomena. A natural calamity can result in fatalities or destruction of property, and usually leads to economic harm, the extent of which is determined by the afflicted population’sability to bounce back and the availability of infrastructure.
Categories of Natural Disasters/ Catastrophes
Floods
A flood is the result of water overflowing and covering land. According to the EU Floods Directive, a flood is defined as the temporary  inundation of territory that istypically not submerged in water. Flooding can occur when the amount of water in ariver or lake exceeds its  capacity, causing the water to overflow and breach its normal borders. The size of a lake or other body of water may alter due to seasonal variations in precipitation and snow melt. However, it is not considered a substantial flood unlessthe water submerges land that is utilized by humans, such as villages, cities, populated areas, highways, and farms.

Introduction

Since the dawn of the civilization when mankind started agriculture, soil erosion has been the single largest environmental problem and has remained so till date (Sullivan, 2004). This is so because removal of the topsoil by any means has, through research and historical evidence, been severally shown to have many deleterious effects on the productive capacity of the soil as well as on ecological wellbeing. Doran and Parkin (1994) captioned the impact of soil erosion in their popular maxim that “the thin layer of soil covering the earth’s surface represents the difference between survival and extinction for most terrestrial life”. Soil degradation implies decline in its capacity to provide ecosystem services (ESs) of interest to humans and useful to nature’s functions. Principal processes of soil degradation are erosion, salinization, nutrient and carbon (C) depletion, drought, decline in soil structure, and tilth. Examples of ESs provided by soil include ecological/supporting (biomass production, nutrient cycling), regulating (water purification and flow, C sequestration, temperature fluctuations), provisional (food, fiber, fuel, and forages), and cultural (aesthetical, spiritual, and cultural). Erosion-induced degradation diminishes soil’s capacity to provide ESs, and support ecosystem functions.

Although fertile top soils could be lost when scraped by heavy machineries (Ngwu et al., 2005), the key avenues of topsoil loss include water erosion and wind erosion. Sometimes erosion can be such gradual for so long a time as to elude detection in one’s lifetime, thus making its adverse effects hard to detect. Eswaran et al., (2001) propose an annual loss of 75 billion tons of soil on a global basis which costs the world about US $400 billion per year. A review of the global agronomic impact of soil erosion identifies two severity groups of continents and reveals that Africa belongs to the more vulnerable group (Biggelaar et al., 2004). Soil erosion by water seems to be the greatest factor limiting soil productivity and impeding agricultural enterprise in the entire humid tropical region. This is evident in many regions of Africa (Dregne, 1990), mainly in the humid and subhumid zones of Sub-Saharan Africa (SSA) where population pressure and deforestation exacerbate the situation and the rains come as torrential downpours, with the annual soil loss put at over 50 t ha⁻¹ (FAO, 1995).

In simple words natural resources can be defined as any part of our environment such as land, air, minerals, forest, rangeland, wild life, fish and human beings.

The sum total of all physical, chemical, biological and social factors which compose the surroundings of man is referred to as environment and each component of these surroundings constitute a “resource”.  The natural resources are land, water, air, minerals, forests, rangeland, wild life or even human beings known as natural resource.

The five basic natural resources are energy, matter, space, time and diversity.

Conservation has always been one of the most important applications of ecology.Unfortunately, the term “conservation” suggest “hoarding”, as if the idea were simply to ration static supplies so that there would be some left for the future. In the eye of the general public the “conservationist” is too often presumed to be an antisocial person who is against any kind of “development”. What the real conservationist is  against  is unplanned  development  that breaks  ecological  as  well as human laws. The true aim of conservation, is two fold–
    
(1)     To ensure the  preservation of a  quality  environment that considers esthetic and recreational as well as product needs; and  
    
(2)     To ensure as continuous yield of useful plants, animals and materials by establishing a balanced cycle of harvest and renewal.

Forests are valuable renewable resources for humanity on Earth. The country’s forest cover has been estimated to comprise 19.39% of its entire geographical area. Forests consist primarily of trees that offer wood that can be transformed into solid, liquid, and gaseous fuels. Forests play a crucial role in regulating the Earth’s temperature by serving as carbon dioxide filters. They provide habitats and shelters for numerous species and also contribute to the visual beauty of the environment. Forests supply the necessary resources for a range of wood related industries, including pulp and paper, composite wood, rayon and other synthetic fibers, sporting goods, furniture, boat
construction, and matches. Timber plays a crucial role in the construction of buildings.Various products, such as bamboos, resins, gums, oils, fibers, medicines, katha, lac, shellac, etc., are derived from forests.
The country’s forest cover has been calculated to be 637,293 square kilometers, accounting for 19.39% of the country’s total geographic area. This falls short of the stipulated requirement, which is 30% of the entire land area. The geographic region is comprised of 11.48% dense forest, 7.76% open forest, and 0.15% mangrove. World Forest Day is observed on March 21st, while National Forest Day is celebrated on September 11th.

“Natural” means an ecosystem not influenced by man and resources means that reserve stock of supply which living things can take from nature for sustenance of life. In reference to man, natural resources can be defined as those natural reserve stocks of supply which man utilizes for his sustenance and welfare. The reservoirs of natural resources are the sun,  the  atmosphere,  the  lithosphere  and the  hydrosphere.  Natural resources include energy, air, water, soil, minerals, plants and animals. The nature of resource depends upon many factors such as scientific and technological development of the society, profession of that particular society, and culture.

Natural resources are the resources present naturally in the environment. These resources are used by human being for their survival. Minerals, building stones, forests, and various energy resources are known as natural resources. Natural resources have been extracted and utilized since ancient times but as the population increased, the demand of natural resources are increasing day by day.

The sun is a hot ball of glowing gases at the heart of the solar system. Its radiant energy is practically the only energy source to the earth. Very small and insignificant quantities of energy are available from other sources such as the interior of the earth, the moon, and other stars. Without the sun’s intense energy and heat, there would be no life on earth.

PROPERTIES OF SOLAR RADIATION

The mean distance of the sun from the earth, also known as one astronomical unit (1 AU), is approximately 1.496 × 10⁸ km, though the distance varies as the earth revolves round the sun in an elliptical orbit. At this average distance, light travels from the sun to earth in about 8 minutes and 19 seconds. The energy of the sunlight supports almost all life on earth by photosynthesis, and drives earth’s climate and weather. The minimum sun-earth distance is about 0.983 AU and the maximum is approximately 1.017 AU. The earth is at its closest point to the sun (perihelion) on around January 3 and at its farthest point (aphelion) on around July 4.

The sun makes up about 99.86% of the mass of the entire solar system. The visible disk or photosphere has a radius of 6.599 × 10⁵ km, and the solar mass is 1.989 × 10³⁰ kg. The sun is a completely gaseous body. The chemical composition (by mass) of the outer layers of sun is 71% hydrogen, 26.5% helium, and 2.5% heavier elements like oxygen, carbon, neon, and iron among others. Since the sun is not a solid body, different parts of the sun rotate at different rates. At the equator, the sun spins once about every 25 earth days, but at its poles the sun rotates once on its axis every 36 days.

5.1 The Need

In spite of the considerable experience and quite a few facilities available in the country, the growth of application of isotope techniques is not commensurate with India’s size, its climatic and hydrogeological diversity and the sheer range of its water resources problems.

The situation may not be unique to India and other developing countries. Australia also appears to be facing a similar problem. A recent publication [1] says ‘the limited uptake of the method may be due to a number of factors. Until relatively recently, isotope hydrology has remained a largely academic pursuit, or measurements were the domain of national atomic energy agencies. A large fraction of information lies buried in the grey literature or in arcane technical journals. Interaction with local or regional water resources agencies has been the exception rather than the rule’

India has probably a stronger case for a more effective use of isotope techniques. A large portion of groundwater occurs in hard rocks in India. Normal hydrogeological and geophysical methods cannot fully describe such groundwater regimes to effectively plan their exploitation. It is essential to apply tracer hydrology methods, especially isotope geochemical techniques, for a comprehensive understanding of the systems. The examples of Manikaran geothermal springs, seepage studies in Salal tunnel and in some dams, given in the earlier chapters come under this category. Studies on percolation tanks in basaltic terrain and on recharge processes need isotope support.

It will not be long before we would be planning to exploit very deep ground waters (>500 m), both in the hard rock terrains of peninsular India as well as in the Ganga plains to meet our ever growing need for water. We would need good understanding of the recharge processes to these deep ground waters. Isotopes will have a large role in such investigations.

Arid zone hydrology is yet another area where the potential of isotope techniques has been effectively demonstrated for the characterization of the recharge processes, both palaeo and modern, and including the role of ancient rivers.

Abstract

Water scarcity and soil erosion are the two most severe problems in arid region of Gujarat, particularly in Kachchh district being entirely under hot arid climate. Present study examines need of soil and water conservation measures in Kachchh district utilizing topographical details and 34-year (1980-2013) annual rainfall data for ten rainfall gauging stations. The impact of three factors, i.e. rainfall, topography and drainage pattern, on the water scarcity and soil erosion was studied. The rainfall characteristics in the study area were explored by computing basic statistical properties, plotting rainfall bar charts and drawing box-whisker plots. Furthermore, topographic features are examined by using Google Earth image and available topographical details. Drainage characteristics and pattern are explained and usefulness of farm pond for water conservation is demonstrated.

Abstract

Satellite imagery interpretation has shown the existence of a major Palaeochannel system in the Great Indian desert. These palaeochannels belong to the mythological Sarasvati river, which seems to have flowed southwesterly close to the Aravalli hill ranges and joined the sea in the Great Rann of Kutch. Subsequently it seems to have shifted northwesterly, and more precisely in an anti-clockwise direction and got buried in the desert in Anupgarh plains. While its oldest course is the now misfit Luni river, its final trace is now represented by Ghaggar river. Whereas its overall northwesterly migration is attributed to NE-SW trending cymatogenic arching along the Great Rann of Kutch in the southwest to the Siwalik hills in the northeast, its multivariate palaeodrainage is attributed to block faulting and land subsidence in the Bikaner sector.

Introduction

Introduction

Pulses belong to the taxonomic family Fabaceae, containing over 18,000 species divided into the three sub-families Mimosoideae, Caesalpinoideae and Papilionoideae. Pulses are commonly cultivated for several decades in all over the world because of the nutritional value of their seeds. Among different pulses, soybean, chickpea, common bean, cowpea, green gram, black gram and pigeon pea contribute significantly to serve the major protein source for the diets of large numbers of people living in Asia, Africa, and South America.

Production and Productivity of Pulses in india

In India, the production of pulses has not been able to keep pace with their domestic demand, resulting in import of 4-5 million tonnes of pulses per annum, especially from the countries like Canada, Myanmar and Australia to meet its domestic requirement (Kumar et al., 2018). India is the largest producer (around 25% of global production), however it consumes 27% and imports around 14% of its pulses requirements. The yield of pulses in India is quite low at 781 kg/ha which might be due to various factors. Pulse crops does not show any significant increase in area and production during 1950-51 to 2009-10, however, significant growth in area and production has been recorded during the last five years (i.e., 2010-2011 to 2016-17), with the adoption of high yielding varieties, increased usage of agricultural inputs like fertilizers and manures etc. The pulses under irrigation are cultivated in about 37% of the area while 63% of pulses are grown under rainfed conditions.

The productivity of pulses has increased about 77% at 779 kg/ha during 2016-17 from the level of 441 kg/ha during 1950-51. It is imperative to mention that the New Agriculture Technology (NAT) introduced during mid-sixties has increased the production of food-grains from 50.82 million tonnes during 1950-51 to 275.68 million tonnes during 2016-17 with the increase in area from 97.32 million hectares to 128 million hectares. In order to achieve self- sufficiency in pulses, the projected requirement by the year 2025 is estimated at 27.5 MT and to meet this requirement, the productivity needs to be enhanced to 1000 kg/ha.

It is important to reflect on the path we have traversed throughout this book. We embarked on a journey tracing the evolution of how weather and climate insights are applied to the intricate world of agriculture. From rudimentary observations to the sophisticated analyses of modern agrometeorology, we‘ve witnessed a growing understanding of the critical interplay between atmospheric conditions and crop production. We‘ve explored the groundbreaking integration of remote sensing technologies, offering an unprecedented bird‘s-eye view of agricultural landscapes, and the power of Geographic Information Systems to contextualize this data within specific spatial boundaries. The emergence of advanced data analytics, including the transformative capabilities of Artificial Intelligence and Machine Learning, has been a recurring theme, demonstrating how vast datasets can be harnessed to extract meaningful patterns and drive predictive insights.
• This progression has culminated in the central concept of precision agrometeorological advisory services – the focus of our in-depth exploration. We‘ve examined how moving beyond generalized recommendations towards tailored guidance, customized to the unique characteristics of individual farms and fields, represents a paradigm shift in agricultural support. This precision approach, underpinned by accurate, localized data and scientifically validated models, holds the key to addressing some of the most pressing challenges faced by today‘s farmers. From navigating the increasing unpredictability of weather patterns and the growing threats posed by climate variability to optimizing the use of increasingly scarce and expensive resources like water and nutrients, precision agrometeorology offers practical and impactful solutions. It empowers farmers to make timely and informed decisions, minimizing risks, maximizing efficiency, and ultimately enhancing the productivity and sustainability of their agricultural endeavors. This empowerment is not just about boosting yields; it‘s about fostering greater economic stability, promoting environmental stewardship, and ensuring food security for a growing global population.
This final chapter, „Next Generation Agrometeorology: Empowering Farmers with Precision,“ is designed to consolidate the wealth of knowledge and insights we‘ve gathered. We will synthesize the key findings and highlight the practical implications of embracing these next-generation approaches. Beyond a simple summary, we aim to provide a clear understanding of how the principles

The most oxidizable form of nitrogen is nitrate nitrogen (NO3 -N), which is found in minimal amounts in surface waters but can reach considerable concentrations in some aquifers. An essential plant nutrient, nitrate also contributes to eutrophication in receiving water bodies.
Principle
Nitrate reacts with phenol disulphonic acid and produces a nitro-derivative which in alkaline solution develops yellow colour due to rearrangement of its structure. The yellow colour follows Beer’s law and is proportional to the concentration of nitrate present in the sample. Ultraviolet (UV) technique measures the absorbance of nitrate at 220 nm, which is suitable for screening uncontaminated water (low in organic matter). A second measurement made at 275 nm, may be used to correct the nitrate value (because 275 nm is not absorbed by nitrate, but absorbed by other matter). The nitrate calibration curve follows Beer’s law up to 11mg NO3 -N /L.
Reagents
1. Stock nitrate solution (1ml=100 µg NO3 -N): Dry potassium nitrate (KNO3) in an oven at 105 oC for 24 h. Take 360.9 mg potassium nitrate and dissolve in distilled water and dilute to 500 ml. Preserve it with adding 1 ml of chloroform in per 500 ml stock nitrate solution. This solution will stable for at least 6 months.
2. Intermediate nitrate solution (1 ml = 10µg NO3 -N): Take 100 ml of stock nitrate solution and dilute it to 1000 ml of distilled water. This solution can be preserve by adding 2 ml of chloroform per 1000 ml. This Intermediate nitrate solution will stable for at least 6 months.
3. Hydrochloric acid (HCL) solution, 1N: Take 83 ml of hydrochloric acid and dilute it to 1000 ml of distilled water

Nitrite (NO2-) is formed in waters by oxidation of ammonia compounds (by aerobic nitrifying bacteria, e.g. Nitrosomonas) or by reduction of nitrate (by facultative anaerobic denitrifying bacteria, e.g. Pseudomonas). Such oxidation and reduction may occur in wastewater treatment plants, water distribution system, and natural waters. As an intermediate stage in nitrogen cycle, it is unstable. Very high nitrite levels are usually associated with waters having unsatisfactory microbiological activity.
Principle (Colorimetric method)
When nitrite (NO2 -) as nitrous acid (HNO2) mixes with sulfanilamide in an acidic environment (pH 2-2.5), a diazonium salt is created. This salt then combines with N-(1-naphthyl)-ethylenediamine dihydrochloride (NED dihydrochloride) to make a vivid pinkish red azo-dye. The amount of nitrite in the sample directly correlates with the colour that is created. At 543 nm, the colour follows Beer’s law up to 180 µg/L with a 1 cm light path. By diluting a sample, a higher nitrite concentration can be determined. Sulfanilamide + HNO2 + HCl ? Diazonium salt + H2O.
Diazonium salt + NED-dihydrochloride ? Red colouredazo dye

12.1 Introduction-Nitrogen

Nitrogen is a chemical element which has the symbol N and atomic number 7. Elemental nitrogen is a colourless, odourless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.1% by volume of Earth’s atmosphere. Nitrogen is a constituent element of all living tissues and amino acids. Many industrial important compounds, such as ammonia, nitric acid, and cyanides are made up of nitrogen.

12.1.1 History

Nitrogen (Latin nitrogenium, where nitrum (from Greek nitron) means “native soda”and genes means “forming”) is formally considered to have been discovered by Daniel Rutherford in 1772, who called it noxious air or fixed air. That there is a fraction of air that did not support combustion is well known to the late 18th century.

Argon was discovered when it is noticed that nitrogen from air is not identical to nitrogen from chemical reactions. Compounds of nitrogen were known in the Middle Ages. The alchemists knew nitric acid as aqua fortis (strong water). The mixture of nitric and hydrochloric acids is known as aqua regia (royal water), celebrated for its ability to dissolve gold (the king of metals). The earliest industrial and agricultural applications of nitrogen compounds involved uses in the form of saltpeter (sodium- or potassium nitrate), notably in gunpowder, and much later, as fertilizer, and later still, as a chemical feedstock.

14.1. Determination of Total Nitrogen in Soil (Modified Kjeldahl Method)

Nitrogen mostly present in soil in organic form. Relatively small amount of nitrogen usually occur in ammonium and nitrate form, the available form. The Kjeldahl method of total N determination includes both organic and ammonium form and with modification nitrate form of N can also be included.

Abstract

Nitrogen is an important nutrient for growth and development of plants. Presence or absence of nitrogen often affects the amino acid composition of proteins, which may in turn change its nutritional quality. Increase in the elevated CO₂ concentration and temperature associated with future climates are expected to affect the nitrogen use efficiency (NUE), growth and grain yield of wheat (Triticum aestivum L.). Atmospheric CO₂ is steadily rising from the current level of approx 384 µLL^-1 and is expected to rises upto 550 µLL^-1 by 2050. It is predicted that the global temperature would increase by 1.5- 4.5^oC. The main future challenge is to feed nine billion people under an altered climate, as this increase in global temperature would affect, negatively or positively the future crop productivity including wheat depending upon the geographical location. The present book chapter summarizes the potential impact of elevated CO₂ and temperature on NUE of Triticum aestivum L.

Greek scientist Theophrastus (300 BC) advocated legume rotation. As early as 1750 AD it was known that plants require Nitre. Louis Pasteure in 1860 AD stated the possibility of atmospheric nitrogen fixation by microorganisms. Hellriegel and Willfarth (1886) strengthened the views of Louis Pasteure by his observations on the irratic behaviour of legumes to nitrate nutrition. Beizerink (1890) isolated the organism involved in nitrogen fixation. The systematic field experiments conducted at Rothemstead experimental station showed that the plants respond to inorganic nitrogen.

ROLES OF NITROGEN IN CROPS

Plants contain 1-5 per cent nitrogen by weight. It is a structural component of chlorophyll, aminoacids and proteins. Plant proteins contain 16 per cent nitrogen (6.25 × %N = protein). Plants are dependent on protein for their propagation. Cereals possess a threshold protein level below which grain will not form.

For the hundreds of thousands of years that we lived on earth,there were few rapid changes in the atmosphere. It is only in recent times, particularly since the Industrial Revolution, that our activities on earth began to modify our environment in a significant manner.  Industrial pollution has affected the water we drink, the air we breathe, and in general,the biosphere itself.Now noise has joined the bandwagon of pollutants.

Noise certainly comes within the scope of definition of a pollutant that “..... any undesirable change in the physical, chemical or biological characteristics of our air, land and water that may or will harmfully affect human life or that of any other desirable species or industrial process, living conditions or cultural assets, or that may or will waste or deteriorate our raw material resources.”

A sound is a form or energy. Therefore, it has to have an impact on life in one way or the other. Most of the organisms of Kingdom Animalia communicate with each other creating a peculiar sound. Creating sound is inevitable for performing various life activities. Every animal species has the characteristic sound it reflects through its behavior. Whatever all the animals communicate through creating specific sounds is all-natural. Nature, as such is a stupendous repository of a diversity of sounds, all being specific characteristics of life.

Human behavior, however, is highly evolved in terms of creating a variety of sounds. Communication, entertainment, and many behavioral activities are expressed through creating distinctive sounds. There is a difference between natural sounds and the ones human beings create or can create. Humans often generate sounds, not just in a natural manner, but also with various technical aids, that often become unpleasant what we call noise. Creating noise, or noise pollution, seems to be an exclusive characteristic of the human species. Of course, there could be some natural sounds that might occasionally cause havoc to life. Examples are the sounds generated at the time of the volcanic eruption, during an earthquake

Introduction
The term “noise” originates from the Latin word “nausia.” There are negative repercussions of noise pollution on our bodies and minds. In general, the amount of noise and the length of exposure determine how much noise pollution there is. These
days, noise is a constant in our lives due to the advancements in industry, technology, and machinery.
Definition
Unwanted sound released into the atmosphere that poses a health risk is referred to as noise pollution.
The term “unwanted or unpleasant sound that causes discomfort” refers to nose pollution.
Another definition of noise pollution is “wrong sound, in wrong place at wrong time.”
Distinction Between Noise Pollution and Sound Pollution:
Sound is defined as the lowest level of 50 dB that is pleasant to listen to. Noise pollution is defined as any sound that is louder than 95 dB and bothersome to listen to.
Sources of Noise Pollution
1. Factories and industries, community and religious activities, and modes of transportation (air, train, and road) are the primary sources of noise pollution.
2. In metropolitan regions, automobiles, factories, industries, railroads, and airplanes are the main man-made sources.

Introduction

Soil is a vital, complex, and firm layer of the land surface that provides a source of minerals and organic matter interacting with air and water to harbor life forms. (Lobmann et al., 2022). Versatile micro and macro living organisms, i.e., bacteria, fungi, and actinomycetes, inhabit soil and contribute to its quality, health, and inevitable role in serving the environment (Elsakhawy et al., 2022). Soil roots for a variety of crucial functions which involve ecosystem services or socioeconomic activities, e.g., biomass production, climate gas fluxes of CO2 , N2 O, and CH4 , water cleaning, storage and supply, foundation of construction and provision of construction materials, or provision of habitats etc. The responsibility of soil in sustaining life on earth by providing and conserving resources is not negotiable.

This chapter introduces non-timber forest products (NTFPs) as important biological resources supporting rural livelihoods, local economies, and forest-dependent communities. It examines the definition, scope, classification, diversity, and importance of NTFPs in India. The chapter also discusses value chains, market dynamics, trade, sectoral challenges, and constraints affecting their sustainable utilization. Particular attention is given to conservation, policy frameworks, community livelihoods, and a case study of NTFPs in Maharashtra. The chapter emphasizes the need to balance resource utilization with sustainable forest management and biodiversity conservation.

7.1. Developing Sector in Scientific and Technological Approach of Waste Management

From the very past, many traditional practices have been put into use for waste management like landfilling, composting, and recycling, which are practiced even today. However, the boundless upsurging waste compels the modern world to modify the traditional methods or to introduce innovative techniques with the grace of technology

The study of soil organic matter is becoming increasingly important by the day as world agriculture attempts to ensure sustainability of soils, while at the same time striving to enhance food production to feed an ever-burgeoning population. The use of green manures and pasture leys, the return of residues and additions of organic amendments to the soil are often resorted to in an attempt to increase soil organic matter which immensely benefit the physical, chemical and biological make-up of the soil.

Abstract

Groundwater flow modeling in hydrological sciences is one of the main tools used to assess the resource potential in terms of quantity and to predict the future impacts under different stresses/scenarios. This case study is prepared to present the  groundwater flow model for the Osian-Mandore pilot area with 12 villages of Mandore Block and 21 village of Osian Block in Jodhpur district of Rajasthan. The spatial model parameters and spatio-temporal fluxes were acquired and processed using remote sensing, GIS and Groundwater flow modeling interfaces. MODFLOW software was used to model the groundwater flow system in three interfaces PMWIN 5.3.0, Groundwater Modeling System and Visual MODFLOW. 

11.1 Introduction
Having explored the sophisticated statistical methods for analyzing meteorological data and the powerful visualization techniques for interpreting it, we now turn our attention to the very engine that drives modern weather forecasting: Numerical Weather Prediction (NWP). This chapter delves into the intricate science and technology behind predicting the future state of them atmosphere using mathematical models and supercomputers. The challenge of weather forecasting is immense. The Earth’s atmosphere is a chaotic, non-linear fluid system, constantly in motion, with interactions occurring across vast scales, from global circulation patterns to microscopic cloud droplets. For centuries, weather prediction relied heavily on empirical rules, human experience, and the interpretation of synoptic charts. While these methods achieved some success, they were inherently limited in their ability to accurately forecast beyond a day or two, especially for complex or rapidly evolving phenomena.
The visionary idea of predicting weather mathematically was first conceived by Lewis Fry Richardson in the early 20th century. He envisioned solving the fundamental equations governing atmospheric behavior using numerical methods. However, the sheer volume of calculations required made his manual attempts impractical, famously taking him weeks to produce a 6-hour forecast that had already passed. It was only with the advent of the electronic computer in the mid-20th century that Richardson’s dream began to materialize, marking the birth of modern NWP (Fig. 11.1).

Concept of nutrient availability: The ions in the soil solution are available to plant provided they can reach an active root or it can reach them. The concentration of ions in the soil solution at any given moment is however; usually low, except immediately after the application of water soluble fertilizers.

Most of the nutrients are taken up by the plant in the form of cations which are positively charged. Available cations either in the soil solution or held against leaching by negatively charged clay or humus particles are easily taken up by the plants. Other plant nutrients notably phosphorus, boron and molybdenum are taken up by the plant as anions which are negatively charged. The concentration of anions in the soil solution is usually low because they become converted to new less soluble forms e.g., soluble phosphate ions forms less soluble iron or aluminium phosphates. Minerals upon weathering and organic matter upon mineralization release nutrient ions.

Physical factors

However, much readily available nutrients a soil may contain various physical features of the soil make it impossible for the plant roots to absorb it. It then becomes positionally unavailable. These features include hard pans, undesirable soil structures, presence of hard clods, dry soil horizons and water logged situation.

Low soil cation exchange capacity leads to less retention of calcium, magnesium, potassium, copper and zinc.

Introduction

Increase in population in our country with decrease in cultivable land is putting the challenges to the scientists and policy planners for increased food supply. There is very little scope for horizontal increase in cultivable land. Hence, the way to meet the need for providing food to ever increasing population is to increase the production of food per unit area of cultivable land.

Farmers, generally apply fertilizer to soil on blanket recommendation. Sometimes, the addition of nutrients is inconsistent. Sometimes, the application of fertilizer is much higher than the recommended dose. Imbalanced application of fertilizer to soil results in low nutrient use efficiency and low crop yield. There is need of site specific nutrient management for increased crop yield and for achieving higher nutrient use efficiency. Proper care should be taken for selection of fertilizer, method of application of fertilizer, rate of fertilizer application and also time of nutrient supply to the soil. Excess application of fertilizer has an adverse effect on soil health.

Traditional tillage may affect physico-chemical as well as biological properties of soil. Change in tillage practice from conventional tillage to conservation agriculture method may have an impact on soil properties and nutrient dynamics. Conservation agriculture affects soil health, proper fertilizer application, both rate and time, along with efficient use of soil moisture improves nutrient use efficiency. For obtaining a good crop yield nutrient should be available for plants in adequate quantity and in right proportion. Nutrients removed by the crop should be replenished by application of inorganic fertilizers alongwith incorporation of organic manures. Soil test is an important tool for determining the quantity of nutrients available in the soil. Based on soil test values and nutrient requirement of the crop rate of fertilizer to be applied in the soil for the plant is determined. Ample quantity of farm yard manure is not available nowadays. Hence, other organic manure such as town waste, green manure etc should be used.

Salt affected soils occupy 962.2 m ha globally which accounts for 33% of the arable land. In India 8.373 m ha is affected with salts. Of which 2.359 m ha are alkali soils, 3.829 m ha are saline soils and 2.185 m ha coastal saline soils. Reclamation of these soils provides additional area for food grains production and employment.
