4.1 Introduction

With the birth of the new millennium and the advent of Information and Communication Technology, the outlook of academia towards research has completely metamorphosed into a more productive and vibrant activity. Digitalization of data, the convergence of new and challenging insights in one’s own research fields at the world-wide-web and technology generation are being made faster and more reliable. With the arrival of Laptops and Smartphones simultaneously with the facility Wi-Fi, the demand for information of any kind has become unquantifiable! The academic world is no exception, indeed! Such a pang of hunger for information led to considerable investments in infrastructure development. The virtual, electronic, automated world became inseparable from academic and research institutions. Small wonder that with these, the pressures on the institutional and specialized and dedicated libraries are on the increase.

Summary
 
ISFM has been defined in a number of ways – but here an emphasis is placed on finding a way to explain ISFM that makes sense to the intended audience. When combined with general good agronomic practices the combination of improved planting material, chemical fertilizer along with the addition of organic mater, increases productivity.  There are, however, constraints at the smallholder level – in terms of access to farm inputs e.g. seed, credit &labour.This section looks at short and long-term approaches to the application of basic nutrients. The issues of recycling nutrients and the impact of erosion on the nutrients in the soil. There is a review of the pros and cons of ISFM – it does increase yield (4 -6 times more production).  There is a brief outline of the role of cover crops, mulching and conservation tillage as forms of agriculture that can help reduce soil erosion.The section locates the idea of ISFM along side integrated pest management and explores the impact of biological control agents in Ghana and the role of micro-organisms.

Introduction

Food being the foremost basic need gets the priority in expenditure of people, especially poor class. Access to food demands affordability, which depends upon the twin factors namely, income of the people and prices prevailing in the country. Slower growth in income than prices would undermine the purchasing power, resulting in inadequate access to food and calorie consumption. Foodgrains account for about four-fifth of the calorie intake of the poor and an increase in cereal prices could significantly reduce the calorie intake of the poor, as it is sensitive to cereal prices.

Abstract

The toxic materials like arsenic, barium, beryllium, cadmium, chromium, lead, mercury, etc. present in Electronic wastes, in short e-wastes are a great threat to mankind since these contaminate soil, water and air of the surroundings. These E- wastes are mainly defective or obsolete parts of computers, audio-visual systems and electronic & electrical machineries used in the houses, offices and factories. These carcinogenic or hazardous toxic materials are root cause of damage of different parts of human body, untimely death as well as health disaster. Every year the manufacturers and assemblers produce around 1200 tons of electronic scraps in India. Collection of computer wastes from developed countries by greedy Indian business people for sorting out in India aggravates the environmental pollution. ‘Reduce, Reuse and Recycle’ are three important principles to be followed by one and all (Manufacturers, Distributors, Sellers, Buyers to Users) for proper scientific management of electronic wastes. Reverse osmosis, Electrolysis, Condensation, Electrolytic recovery, Filtration, Centrifugation, etc. are some of the important e-waste management technologies used to reclaim different toxic materials. Buyback policy should be made compulsory since Manufacturers can afford to build up infrastructure for reusing and recycling electronic wastes.  More and more use of bio-based plastics, toners, glues, inks will reduce the environmental pollution considerably and save the mankind from extinction.

Abstract

The normal human microbial flora comprises of both aerobes and anaerobes at various sites. Anaerobes are recognised as pathogens causing simple abscesses to life threatening human infections like gas gangrene. They are also incriminated in a large number of mixed bacterial infections and their diagnosis and specific therapy is important for better patient outcomes. The emergence of Clostridioides difficile as an important pathogen causing antibiotic associated diarrhoeas and its emerging resistance to antimicrobial agents has brought anaerobic microbiology into the forefront. Unfortunately, anaerobic clinical microbiology is difficult to practice with long turnaround time, difficult to grow pathogens, new genera and species being discovered based on 16S rRNA sequencing methods and increasing incidence of antimicrobial resistance being reported in anaerobes. This chapter delves into the important aspects required to improve utilization of anaerobic microbiology services and the variety of human infections we encounter in clinical practice due to anaerobic bacteria.

4.1 Defining erosivity and erodibility

Rainfall erosion is the interaction of two items - the rain and the soil. The amount of erosion which occurs in any given circumstances will be influenced by both, and our study of the processes of soil erosion is simplified by considering the two aspects separately.

We know from observation that one storm can cause more erosion than another on the same land, and we also know that the same storm will cause more erosion on one field than on another. The effect of the rain is called erosivity and the effect of the soil is called erodibility. The way they differ is best explained by examples.

Let us imagine an experiment station which has over its whole area exactly the same soil type and slope. Assume also that the whole of the station is covered by a completely uniform crop. If the amount of erosion taking place during each storm were measured, the amount would be influenced only by the nature of the rain. Comparing the effect of one storm with that of another storm would provide a relative measure of the power of each storm to cause erosion, and that is what is meant by erosivity. This will enable us to say that on this imaginary experiment station, storm A caused a soil loss of X kilograms per hectare and storm B caused a soil loss of Y kilograms per hectare. If Y is half of X, then the erosivity of storm B is half of the erosivity of storm A.

To most of us Prof. Swaminathan was a great Scientist, humanist and true global leader. I am blessed to have been associated with Prof. Swaminathan. From a brilliant scholar to a visionary global leader, he had continuously moved to higher and higher level of achievements. The nine decades of his life can be divided in 4 phases – Brilliant & dreamy student, devoted scientist and Science Manager, a visionary and missionary solving the hunger problem and a global citizen and humanist. The vision and drive had taken him to extraordinary heights – Like Maharshi Patanjali has said in Yoga Sutra– “When you are inspired by some great purpose, some extraordinary vision, all your thoughts break their bond. Your mind transcends limitations, your consciousness expands in every direction and you find yourself in a new, great wonderful world.” Among many things, I also recollect his inspiration when I was planning GSFC Science Foundation and later the activities of Gujarat Agricultural University.

Introduction 
There is a significant transformation undergoing in the health insurance sector, driven by technological advancements, shift in the regulatory frameworks and uplifting the consumer expectations towards the sector. There is a rise in the healthcare costs in recent times and as a result the insurers are increasingly Assistant Professor, Department of Business Administration, Girijananda Chowdhury University, Assam challenged to provide sustainable and equitable coverage to ensure the quality of treatments of the patients. This evolving landscape health insurance claims a comprehensive understanding of the upcoming patterns and trends to shape the future of health insurance. The digital health technologies have evolved recent developments in the form of telemedicine, artificial intelligence and blockchain etc are continuously contributing as how insurance providers assess risk, deliver services, and engage with policyholders. These innovations not only enhance operational effectiveness but also empower consumers to play a more vital role in their healthcare decision making. Thereafter, the importance of the value-based care becomes more remarkable and the insurers are exploring new models that focus upon patient outcomes over volume, aligning incentives between providers and payers. Additionally, the technological advancements along with the demographic shifts that includes aging population and the increasing rate of chronic diseases are changing the direction of health insurance. The service providers must transform their plans and policies to meet the diversified needs of a changing population that significantly prioritizes personalized and accessible care solutions. Since the emergence of alternative insurance models such as on-demand coverage, direct primary care, and self-insured employer plans etc., the industry navigates these changes and results a shift away from traditional insurance practices. Health insurance significantly plays a vital role achieving Sustainable Development Goal 3 (SDG 3), aiming to secure healthcare and encourage well-being along with poverty reduction and economic growth of the country. By providing financial safeguard against high-cost medical treatments, health insurance minimises the risk of destructive health expenditures which may lead to positioned the individuals and their families into the line of poverty. As the people in India is having access to better healthcare services, the disparities in healthcare services can be reduced and the equality of healthcare services among all the sections in the society can be attained. It boosts the awareness to access the essential healthcare services that includes maternal health, precautionary care and treatment for non-communicable diseases. However, health insurance stimulates sustainable financing for healthcare with an assurance of pooling the funds equitably to cover the needs of various class of people to enhance the attainment of SDG 3 targets and overall sustainability of global health.

10.1 INTRODUCTION

The fate of plant nutrients in fertilizers added to soils is to be: (1) taken up by crops; (2) retained by the soil; (3) removed in solution in drainage water; (4) lost as a gas; or (5) removed by erosion. These five processes are discussed in this chapter. The purpose of using fertilizers is to increase crop growth and they fail in this unless they are taken up by plants. Table 10.1 gives FAO (1972) data which show that large fertilizer use is restricted to the developed countries which use 65 times the amount used per hectare in developing countries. Within the group of ‘developed’ countries most of North-West Europe uses much fertilizer; outside of Europe large use per hectare is confined to a few countries such as Japan and USA. It is in the developed countries where much fertilizer is applied that efficient uptake of plant nutrients is already important to national economies, and where nutrients lost from agriculture cause eutrophication of natural waters and are regarded as pollutants.

11.1 INTRODUCTION

The heavy metals which, by definition, are elements having a density greater than five in their elemental form, comprise some 38 elements. However, the term usually, and here, refers to twelve metals that are used and discharged by industry, i.e. Cd, Cr, Co, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sn, Zn. Most of the present discussion will centre on those metals that may represent potential hazards to plants or animals; these are Cd, Cu, Hg, Ni, Pb, and Zn.

The heavy metals are widely distributed in the environment, in soils, in plants and animals and in most of their tissues. The concentrations of individual metals in living tissue are ordinarily very low and must be maintained within narrow limits to permit the optimum biological performance of most organisms. Some heavy metals are essential in trace amounts, namely Co, Cu, Fe, Mn, Mo, Zn for plants and, in addition, Cr, Ni, Sn for animals; Cd, Hg, and Pb, have not been shown to be essential for either plants or animals. Deficiencies of the essential metals have been frequently reported and substantial benefits have arisen from correcting these by addition to the soil and subsequent transfer from soil to plant is for most increasing concern about the entry into soil of some heavy metals and the possible adverse effects that they might have on plants and animals and, in turn, on human health. The main sources of these heavy metals are: (i) urban industrial aerosols, created by combustion of fuels, metal ore refining and other industrial processes; (ii) liquid and solid wastes from animals and man; (iii) mining wastes; or (iv) industrial and agricultural chemicals. Although in some circumstances there are direct atmospheric inputs to plants, addition to the soil and subsequent transfer from soil to plant is for most heavy metals the major route of entry into the living tissues of plants, animals, and man. The fate of heavy metals added to soils, including their mobility and reactions in the soil and their subsequent uptake and distribution in plants, is therefore of critical importance in relation to man’s health.

9.1 INTRODUCTION

The annual production of organic carbon by photosynthesis on land is about 6x 10¹⁰ tonnes (Table 9.1), most of which eventually decomposes on or in the top 50 cm of the soil. This organic matter can be in lumps as big as a mature oak tree (say 0.5xl0²m³) or as small as a bacterium (0.5 x 10~¹⁸m³). It can be in material as resistant to decay as oil palm nuts, which persist for years in soil in the humid tropics, or as transient as mammalian protein. Yet in the long run, no fraction of the organic matter in plants and animals can withstand decomposition to carbon dioxide and water. If this were not so, any completely resistant fraction would by now cover the surface of the earth. Although under normal conditions organic matter does not accumulate indefinitely in soil, exceptions can occur, as, for example, when a soil becomes permanently waterlogged. When a geologically stable surface has been under the same vegetation for a long time, the soil approaches steady state conditions, with the annual losses of organic matter balancing the annual input. Thereafter the organic matter content of the soil remains constant, until the next vegetational change or geological catastrophe. This process, in which losses and gains proceed simultaneously, is described as turnover and may be defined (for carbon) as ‘the flux of carbon through the organic carbon in a given sample of soil’. Turnover time is then the amount of carbon in the soil system (or part of that system) divided by the annual input of carbon into the system (or part of that system). Turnover and turnover time will be discussed more fully in Section 9.2.5.

Dr. Chauhan, a celebrated veterinary doctor whose groundbreaking work in rural animal healthcare earned him international accolades, began his journey in a modest setting. Born in 1958 in a  small village near Aligarh, Uttar Pradesh, Amit grew up surrounded by fields, animals, and the rustic charm of rural India. This environment would unknowingly shape his path toward becoming one of the most sought-after veterinary doctors in the country.
A Humble Beginning
The Chauhan family owned a small plot of farmland and a handful of livestock, which formed their primary source of livelihood. His father, was a hardworking farmer who toiled from sunrise to sunset in the fields, while his mother, Prakash Vati Devi, managed the household and cared for their cows and buffaloes. Despite their modest means, the family placed immense value on education. Ramswaroop, an Intermediate passout in his youth which was quite an achievement few in the village had accomplished—dreamed of giving his children a brighter future.
Dr. Chauhan’s early years were spent observing the rhythm of village life. The crowing of roosters, the mooing of cows, and the occasional bleat of goats were the background score of his childhood. While other children enjoyed chasing buffaloes or playing in the fields, Dr. Chauhan was different. His deep empathy for animals was evident even as a child, as he often helped his mother care for sick cows or newborn calves. It was during these moments that the seeds of his future profession were sown.

Introduction 
Nestled in the heart of Karnataka, Tumakuru District is renowned for its verdant landscapes dotted with vast expanses of coconut and areca nut plantations. The region’s unique climatic conditions, characterized by a harmonious blend of sunshine and seasonal rains, create an ideal environment for the growth of coconut palms, which have become a staple of both the local economy and the cultural fabric of the community. Historically, coconut trees have not only provided sustenance but have also played a pivotal role in the livelihoods of many families in Tumakuru. The fruit is a key ingredient in various local dishes and is widely utilized in traditional ceremonies and celebrations. However, the task of harvesting coconuts from these towering trees has long been a physically demanding endeavour. Traditionally, skilled climbers would ascend the tall, slender trunks, utilizing their agility and experience to pluck coconuts by hand. This craft, which once flourished, has now seen a decline, making it increasingly challenging for coconut planters to find professionals who can perform this labour-intensive task. The decline in manpower has made it evident that traditional methods are no longer sustainable. If coconut farmers wish to keep pace with growing market demands, a new approach is necessary one that balances traditional harvesting practices with modern technology. Recognizing this need, innovative minds have introduced the “Coconut Tree Climber”, a mechanized device specifically designed to address the challenges faced by coconut planters. The Coconut Tree Climber is a user-friendly and efficient device that significantly simplifies the process of climbing and harvesting. Built with a strong and adjustable mechanism, the device allows a person to securely climb tall coconut trees with minimal physical effort. More importantly, it drastically reduces the risk of accidents, ensuring the safety of the user. Unlike traditional methods that rely solely on human strength, the device takes advantage of mechanical power, enabling planters to harvest coconuts faster, safer, and more efficiently. This innovation has proven to be a game-changer in the coconut farming industry. Not only does it empower farmers to become self-reliant, but it also minimizes their dependence on skilled climbers. Additionally, the device can be operated by individuals of varying ages and physical strength, making it accessible to a broader range of people. This, in turn, provides new employment opportunities for those who may not have had the physical ability or training to climb trees in the past.

This concluding chapter, “The Future ECG: Predicting a Vibrant Agricultural Heartbeat,” therefore adopts a global lens, acknowledging that the quest for accurate and timely monsoon forecasts is a shared endeavor with worldwide implications. Just as the electrocardiogram serves as a universal diagnostic tool for assessing the health of the human heart, the advancement of monsoon forecasting represents a collective effort to understand and predict the vital “ECG” of agriculture in all monsoon-dependent regions. Throughout this book, we have examined the scientific principles and evolving technologies underpinning monsoon prediction. In this final exploration, we will broaden our perspective to consider how the future of this field will impact agricultural practices and livelihoods on a global scale. The innovations in satellite technology, climate modeling, artificial intelligence, and data analytics that we’ve discussed in the context of the Indian monsoon hold immense potential for enhancing forecasting capabilities in every corner of the world where farmers rely on these seasonal rains. Imagine a future where international collaboration fosters the sharing of data and expertise, leading to a more comprehensive understanding of global monsoon dynamics. Farmers in diverse monsoon-affected regions could benefit from increasingly precise and localized forecasts, empowering them to make informed decisions about planting, irrigation, pest management, and harvesting. This enhanced predictability promises not only to improve yields and reduce risks but also to contribute to greater resilience against the impacts of climate change, which are increasingly affecting monsoon patterns worldwide. “The Future ECG” in this global context signifies a hopeful outlook, one where continued scientific progress translates into a more secure and prosperous future for all those whose lives and livelihoods are intricately linked to the monsoons. It is a vision of a globally vibrant agricultural heartbeat, sustained by the everevolving science of forecasting and the collective commitment to supporting monsoon-dependent communities worldwide.

The final chapter of this exploration into agricultural sciences casts a forward-looking lens on the opportunities and challenges that lie ahead. As global population levels continue to rise, with estimates suggesting we will surpass 9 billion people by 2050, the demand for sustainable and efficient agricultural practices has never been more urgent. Emerging challenges, such as climate change, biodiversity loss, soil degradation, and water scarcity, coupled with rapid technological advancements, are reshaping the landscape of agricultural research and publishing (Fig. 16.1).
This chapter delves into how the integration of advanced technologies, the promotion of open-access publishing, and global cooperation can revolutionize agricultural sciences. It also highlights the importance of equity, innovation, and adequate funding in driving this transformation.
16.1. Advanced Technologies and Their Transformative Potential
In the past decade, advanced technologies like artificial intelligence (AI), machine learning (ML), and big data analytics have become central to scientific inquiry. These tools are now increasingly being applied to agricultural research, offering unprecedented opportunities for innovation. For example, AI-powered predictive models can help forecast crop yields, pest outbreaks, and weather

The future of genetically modified organisms (GMOs) presents a complex and multifaceted landscape, intertwining scientific innovation, regulatory challenges, environmental considerations, and societal acceptance. This article explores the potential advancements in GMO technology, including enhanced nutritional content, increased crop yields, and resistance to pests and diseases. It also examines the ethical and ecological implications, such as gene flow to non-GMO species and the potential impacts on biodiversity. Regulatory frameworks and public perception are discussed, highlighting the need for transparent communication and robust safety assessments. Ultimately, the future of GMOs will depend on a balanced approach that addresses both the opportunities and challenges, ensuring that this technology can contribute to sustainable agriculture and food security in a responsible manner.

Green composites provide opportunities to reduce dependence on petroleum-derived materials while maintaining useful mechanical and functional performance. This chapter examines the fundamentals of green composites and the major challenges limiting their wider adoption. Important issues include poor interfacial bonding, nanoparticle dispersion, variability of natural fibres, mechanical and thermal limitations, processing difficulties, cost, scalability, and commercialization barriers. Nanoparticle reinforcement is explored as a means of improving tensile strength, stiffness, thermal stability, electrical conductivity, and barrier properties. The chapter also discusses green processing, advanced characterization, emerging applications, sustainability assessment, life-cycle assessment, and future research directions for developing high-performance and commercially viable green composite systems.

3.1 Overview of the Global Carbon Market in Pre-Kyoto Protocol Phase

At the First COP in Berlin in 1995, the UNFCCC launched a pilot phase of projects to build experience and “learning by doing”. The pilot phase was termed Activities Implemented Jointly (http://unfccc.int/program/coop/aij/aij_np.html). Under the Activities Implemented Jointly, Annex I Parties could implement projects in other countries that reduced emission of greenhouse gases or enhanced removals of sinks. The number of projects registered under Activities Implemented Jointly has been growing since its launch and as of 2002 (the latest report available) there were 157 projects – 45 percent of which are in developing countries. The total amount of money invested by private sector companies as of 2000 was about $160 million. Because of the expectations that sink projects would be included as a mechanism for achieving targets, several pilot projects were voluntarily implemented involving mostly private sector entities (e.g., electric utility companies, oil companies and environmental non-governmental organisations). Between the beginning of 1996 and the end of 2003, 76 transactions involving carbon sequestration in the LULUCF sector were signed, representing 40 million tCO2-e. Relative to all of the carbon transactions that took place over the same period, sink projects accounted for 21 percent of the total number and 23 percent of the total volume. In volume terms, carbon sequestration projects were the single largest project category, and more than three-quarters of this volume was transacted between 1996 and 1999.
