Several independent research traditions have examined the diffusion of innovations. Fields such as anthropology, geography, and sociology have long aimed to understand current behaviours by tracing the diffusion of techniques and ideas from their origins to their present distributions. Critics argue that this tradition often focuses on descriptive history inferred from patterns of similarity (diffusionism) while neglecting causal processes. Extreme diffusionists sometimes postulated implausible links between societies.

Rural sociologists pioneered the quantitative study of innovation diffusion, with classic studies examining the spread of hybrid corn and 2-4-D weed killer in the American Midwest. This field has produced numerous studies, including many focused on the diffusion of modern techniques to Third World peasants. Similarly, researchers in educational reform have studied the spread of kindergartens, driver training, and modern mathematics curricula. Currently, there may be studies on the diffusion of General Education requirements in U.S. universities. Medical sociologists have investigated how new drugs spread among communities of physicians. Additionally, communications and marketing experts study how propaganda and advertising persuade people to adopt new ideas and products.

Introduction

Preceding chapters discuss the essentials of probiotics, their role in maintaining gut health in combination with prebiotics and significance of systematic classification of probiotic isolates. Further, to draw an idea how probiotics function in the gut, it is essential to know the interaction of probiotics with other microorganisms in the gastrointestinal milieu - the site of their probiotic action. Knowledge in the ecology of probiotic microorganisms in host environment such as gut gives an ideal picture of their functioning manner and the factors (both host and microbial) responsible for it.

Study of microbial ecology in the gastrointestinal tract is very difficult since gut harbors highly diversified microflora that varies not only at species level but also at individual level. The diversity of gut microflora in two healthy individuals of same species may exhibit variations in their composition and it may be influenced by geodemographic factors also. In this regard, the present chapter deals with the study of ecology of Lactobacillus- most commonly used probiotic bacteria in the gastrointestinal tract which in turn helps in framing selection criteria for screening of potential probiotics.

Recent studies on interaction between human and gut microflora discussed that co-evolution between microorganisms and their host have contributed for the development of a very complex microbial diversity in the gut. Highly diversified microflora in the human gut is a consequence of natural selection at two levels, top-down and bottom-up selection pressure. Hierarchy theory expounds that higher levels compel lower levels for possible organizational solutions i. e. organisms at the higher levels govern the structure or population dynamics of an ecosystem while on contrary lower levels control the structure of ecology when bottom-up level is the selection pressure. In case of interaction between human and gut microflora, being host human is at higher level in the hierarchy for selection and as mentioned above, top down selection pressure is driven by higher levels; host selects the beneficial microorganisms for functional redundancy leading to the development of a microbial community with divergent microbial divisions. Chances for lateral gene transfer also thought to influence the selection process and there by structure of the microbial community. On the other hand, competition among the members of host selected microbiota exert bottom up selection pressure resulting in the development of highly specialized genomes with functionally prominent set of genes. Natural selection at host level obviously favors functionally constant microbial communities which benefits the host with functional redundancy encoded in their genomes. Mean while bottom-up cell-level selection pressure aspire to favor niche specialization to avoid competition between the members of microbial community. In order to be a part of specialized niche, to become more potent microorganisms adapt a particular set of abiotic and biotic factors within the habitat by acquiring new sets of genes essential for their survival and thus escape the competition from decrepit microbial species.

Introduction

Over the course of past decades India is one of the fastest growing economies of the world with a robust growth and transformations in its economy. In this journey subsidies played a crucial role in influencing market behaviour, support industries, address market failures, and achieve social and economic objectives of the country. Now what actually the economic subsidies are.

Subsidies are financial incentives provided by governments to individuals, businesses, or industries in the form of cash, grants, or tax breaks to influence economic behaviour and outcomes. They aim to correct market failures, promote specific industries, encourage production, and address economic challenges. Subsidies can be direct (cash payments) or indirect (tax breaks), benefiting recipients by reducing burdens or promoting certain actions. They are in the public interest, supporting social goods or economic policies.

The importance of subsidies lies in their ability to offset market failures and externalities, leading to greater economic efficiency. By providing financial aid, subsidies can stimulate production, increase supply, lower prices for consumers, and drive economic growth in targeted sectors. They play a crucial role in stabilizing economies, responding to economic shocks, and promoting long-term economic stability. Subsidies can also help governments address poverty, encourage investment in research and development, and support essential industries like agriculture, energy, and healthcare.

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.

Building and honing up skills for managing any business is an important endeavor. Regardless of whether one is running a small business or a large company individual with good management skills are always essential. The role and structure of the farm business in modern agriculture is changing.

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

It is said that Rome was not built in a day. Similarly, Extension was not master minded by one individual; rather it evolved through hard work of extension professionals around the world over more than a country.

The necessity of a human being is food, for which he must rely on agriculture. The agriculture to achieve its expected growth must depend on several factors which include technology, research and obviously extension. The basic function of agricultural extension is to train, teach and guide farmers. Agricultural extension’s primary role is to mentor, instruct, and train farmers.

Introduction

Agriculture has always been linked with prosperity, man power and the ability to feed and raise human population. In earlier times, humans as man power were deployed on the fields to do all the necessary operations to cultivate the crops, but during the industrial revolution, with development of different farm machines the uses of human labor on the fields were drastically decreased. Further, with advancement of technologies and more availability of computers, Artificial Technology (AI) has been gaining momentum in recent years.

AI has the potential to transform the agricultural sector through cost reduction and increased crop yields, and minimizing environmental impacts. AI can help farmers better manage their land, improve crop quality, and increase their productivity In addition, AI can be used to monitor and analyze the health of crops, livestocks, and soils to identify issues and assist in their resolution. The primary idea of using artificial intelligence in agriculture is due its adaptability, superiority, and cost-viability. The customary techniques that were utilized by the farmers were not adequate enough to satisfy their necessities. (Khan et al. 2022) With the right implementation and technology, AI can be an invaluable tool to help farmers increase their efficiency and profitability. In today’s rapidly evolving world, where the demand for food continues to escalate amidst concerns over environmental sustainability and resource scarcity, Artificial intelligence (AI) has become a transformative force in agriculture, from optimizing crop production and resource management to enhancing decision-making processes. Globally, AI is changing how we approach farming techniques.

1. Introduction

Climate change includes higher temperatures, changes in rainfall patterns, alterations in the frequency and distribution of weather events such as droughts, storms, floods, and heatwaves, sea-level rise, and the consequent impacts on human and natural systems (Riedy, 2018). Climate is the average weather in a given area over a longer time. A description of climate includes information on, for example, “the average temperature in different seasons, rainfall, and sunshine. Also, a description of the chance of experiencing extremes is often included. Climate change is any systematic change in the long-term statistics of climate variables such as temperature, precipitation, pressure, or wind sustained over several decades or longer. Climate change can be due to natural external forcings (changes in solar emission or changes in the Earth’s orbit, natural internal processes of the climate system), or it can be human-induced” (Buonocore, 2022).

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.

ABSTRACT

Economic growth of a country depends upon the skills of its people and the application of knowledge, inherited or acquired by them. Optimum utilization of human resources undoubtedly leads to considerable degree of economic development of a country. There are over one billion youth (aged 15 – 24) in the world today. Eighty five (85) per cent of these youth live in the developing world, where 99 per cent of population growth is occurring. Around 50 per cent of the population in developing countries live in rural areas. Some 61.5 per cent of youth live in Asia. Many youth are unable to reach their potential because of poverty and associated hunger and poor health. Also, education and training is often of poor quality and is irrelevant and inappropriate for the needs of rural youth and of the labour market. So although many youth today are more educated than their parent’s generation, they often do not possess employable skills. Even when good education and training are available and youth have been well trained, obstacles still exist, such as social customs (for example, caste and traditional values), lack of support mechanisms and lack of access to capital. Corruption is also a problem, as are structural impediments (institutional and governmental). Also, because youth numbers are growing faster than the rate of job creation, too few decent employment opportunities are available for the number of youth seeking them. The result is that a large number of youth are unemployed or underemployed. Not only do these youth lack income, they lack a means of gaining respect and a sense of belonging in their communities. Inability to find decent employment means youth often find employment in the informal sector, with poor working conditions and pay. Rural youth will often look to urban areas for employment and move to cities that adversely affect the household farming in India.

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.
