Overview of the Chapter’s Focus on Agroecology and Soil Sustainability

The ecology and biodiversity of our globe are being threatened by human activity, notably unsustainable agriculture methods. This chapter explores the vital function of agroecology, the intersection of ecological and agricultural concepts, in promoting sustainable farming systems. Soil sustainability, essential for effective and resilient agrarian operations, is critical to this strategy. Here, we give an overview of these key terms and talk about the pressing need to switch to sustainable agriculture methods to preserve the  health of the soil, increase food security, and create adaptable environments.

1. Introduction to Water Resources in Agriculture

Water, the quintessential life force for agriculture, intricately intertwines its significance throughout the fabric of global farming practices.

1.1 Significance of Water in Agricultural Practices

1.1.1 Sustenance of Plant Life

• Beyond its role as a life sustainer, water emerges as the very essence that propels plant development. It acts as the vital catalyst for photosynthesis, the engine of plant growth. This intricate process is the heart of the plant’s ability to convert sunlight into energy, driving robust development from seed germination to harvest.

Introduction

Cucurbits, a versatile and economically significant group of plants within the Cucurbitaceae family, encompass a wide array of popular vegetables such as cucumbers, pumpkins, squash, zucchinis, and melons. These cucurbit crops are not only vital components of global diets but also key players in agriculture. Also, cucurbits are used as fibre source and for utensil preparations, decorations, and ceremonial and medicinal purposes (McGrath 2004). However, their productivity and quality are frequently compromised by a range of diseases. In this chapter, we embark on a comprehensive exploration of the diseases that afflict cucurbits, including their names, symptoms, causative agents, etiology, disease cycles, favourable conditions, and strategies for effective management.

Introduction

Food adulteration compromises quality of foods and causes human health hazards is a menace mankind had been facing since ages. Spice adulteration scandals in the year 2004, Horse gate scandal in Europe during 2013 are famous examples of food fraud. Various forms of food adulteration and cheating such as substitution of cheaper food components in place of original product, addition of non-permitted substances, and false claims by misbranding or mislabeling are prevalent from time immemorial (Spink et al 2019).

A. Non-thermal Processing

Non-thermal processing encompasses a diverse range of food preservation and treatment techniques that do not rely on heat as the primary means of achieving microbial inactivation or quality preservation. Unlike conventional thermal methods such as pasteurization and sterilization, which involve exposing food to elevated temperatures for a specified duration, non-thermal processing methods operate at or near ambient temperatures. These innovative technologies offer several advantages, including the preservation of sensory attributes, retention of nutritional quality, and minimization of detrimental effects on food texture and f lavour (fig 1).

3.1. Introduction

Rice is grown in varying geographical locations and climatic situations. Most of the rice area lies between the equator and 400 N latitude and between 700 and 1400 E longitude. It grows well from tropical to sub-tropical warm and temperate climatic regions up to 400 S and 500 N of the equator. However, the highest yields are obtained in the region between 300 and 450 N of the equator. The average yield generally increases as the countries are situated further away from the equator (Chatterjee and Maiti, 1985). In India, rice grows in regions from 80 N to 350 N latitudes under widely varying conditions of the land, rainfall, altitude and climatic conditions. It is grown at the sea level in river deltas as in parts of Kerala, as deepwater in states of West Bengal, Assam and Bihar; at high altitudes of 914 to 1524 m or even more as in Kashmir, and in the slopes of the Himalayas. A temperature range of 200 C to 37.70 C is required throughout the life period of rice crop.

8.1. Biofloc aquaculture

Among the innovations in the field of aquaculture, biofloc technology (BFT) has attracted great attention due to its ability to foster the goals of sustainable aquaculture (Khanjani et al., 2022a). If implemented correctly, BFT capitalizes on the existing organisms in water to significantly reduce water use and environmental impact and increase biosafety at farms (Avnimelech, 2012).

9.1. Introduction

Human dependence on natural processes for the goods and services provided by nature, especially food, fuel and fibre, has been a known fact. In recent times, the value of less tangible services, such as climate control, water f iltration, and soil fertility, as well as recreational and cultural services has been emphasized also. Ecosystem services underpin human existence, health, and prosperity. It has been beneficial to humans through the transformations of resources (or environmental assets, including land, water, vegetation, and the atmosphere) into a flow of essential goods and services like clean air, water, and food (Costanza et al., 1997). Ecosystem services are those functions of ecosystems- including agroecosystems that are useful to humans or supportive of human well-being (Kremen, 2005). Services provided by ecosystems receive little notice for their support to human civilization often leading to poor management of the ecosystems. Land use systems influence ecosystem functions, which determine the supply of ecosystem services. Land and water resources are under considerable pressure from the expansion of cultivated and residential lands. Diverse land use in agrarian landscapes not only fosters biodiversity, but also provides potential ecosystem services such as air cleaning by vegetation, natural water filtration by plant roots, natural pest suppression, soil conservation, nutrient retention, and crop pollination by insects, etc. Lowland floodplains or waterlogged land areas are generally more conscious of the benefits provided by ecosystem services. It is important to create awareness among the people on provisioning services provided by ecosystems, such as crops, biofuel, fresh water, natural medicine, wildlife, and several cultural services. Managing ecosystem services, which link human well-being to conservation outcomes, is essential for achieving the sustainable development goals (SDGs) of the United Nations (Zhang, 2017).

Introduction

Strategy is a critical aspect of any organization, as it helps to align resources, capabilities, and competencies to achieve the goals and objectives of the organization.

Strategic Management Process: The strategic management process com prises four essential stages: analysis, formulation, implementation, and evaluation. Each stage plays a crucial role in attaining desired outcomes and maintaining the organization's competitiveness.

Analysis Stage: During the analysis stage, the organization thoroughly examines its internal and external environments. The internal analysis assesses the organization's strengths and weaknesses, while the external analysis explores the opportunities and threats present in the market.

Formulation Stage: The formulation stage involves developing strategies to achieve the goals and objectives of the organization. This stage involves selecting the most appropriate strategy based on the results of the analysis.

This chapter provides a comprehensive overview of the randomized block design (RBD), detailing its theoretical concept, layout, and a detailed segment on pooled ANOVA concepts. It explains the mathematical models for RBD and how to interpret the results from ANOVA tables in this context. The chapter also offers step-by-step guidance for analyzing RBD, Factorial RBD, and pooled RBD ANOVA using R.

Randomized Block Design

The RBD is a widely used experimental design in statistics and research, particularly when dealing with certain specific conditions:

• Homogeneity within blocks: RBD is ideal when there is inherent variability in the experimental units, but this variability can be grouped into homogenous blocks. Each block contains a complete set of treatments, and the blocks themselves account for the variability.

• Principles of experimental design: RBD adheres to the core principles of experimental design, namely randomization, replication, and local control. Randomization is used within blocks to assign treatments, ensuring that the comparison of treatments is fair.

• Replication across blocks: In RBD, each treatment is replicated across different blocks. This replication enhances the reliability and robustness of the experimental results.

• Managing uncontrolled variability: RBD is particularly effective in field experiments or situations where external variability (e.g., soil type, light conditions) cannot be completely controlled. By grouping similar units into blocks, RBD effectively reduces the impact of this uncontrolled variability on the treatment effects.

• Improvement in experimental accuracy: The use of blocks to organize the experimental units usually leads to a reduction in the error variance compared to CRD. This enhances the accuracy and precision of the experiment.

1.1 GENERAL DESCRIPTION

There is a folk tale from India which is mentioned under relevant situations. This tale teaches how different perspectives lead to different points of view. The tale of the blind men and an elephant originated in the ancient India, from where it has been widely spread to different parts of the world. This famous ancient tale mentions about six blind men who had never come in contact with an elephant during their lifetime and who know and visualize what the elephant appear like by touching it and feeling. In the tale it is highlighted that every blind man touches a different part of the elephant's huge body, but only one part, such as the leg, ear, tail, body or the tusk. These blind men then go on to narrate about the elephant on the basis of their touch and feeling and their recount of the elephant varied widely from each other. They were told that elephants could trample forests, carry huge loads and is very big in size. The six blind men were taken to the elephant and asked how it look like (Fig.1.1). The first blind man reached out and touched the side of the huge animal. "An elephant is smooth and solid like a wall!" he declared. "It must be very strong and powerful." The second blind man put his hand on the elephant's trunk. "An elephant is like a giant snake," he said. The third blind man felt the elephant's pointed tusk. "I was right," he decided. "This creature is as sharp and deadly as a spear." The fourth blind man touched one of the elephant's big ear and announced "I believe an elephant is like a huge fan or may be a magic carpet that can fly over mountains and treetops". The fifth blind man touched one of the four legs. "What we have here," he said, "is pillar of a house." The sixth blind man gave a tug on the elephant's coarse tail. "Why, this is nothing more than a piece of old rope and it appeared to him dangerous, indeed”.

Different basic as well as advanced laboratory equipment need to be used in a laboratory while conducting experiments. Many of them like pH meter, laminar air-flow hood, viscometer, thermometer, magnetic stirrer, microwave ovens, incubators, sand-bath, water-bath, oil-bath, etc. are the basic and simple equipment which require to be used routinely while conducting experiments in a laboratory. However, basic knowledge of their operation, handling procedure, when to be used, how to be used, and more importantly what not to be done with it, etc. are essential for keeping them in serviceable condition as well as for the accuracy/precision in their operation. In this chapter, we will discuss about some of the routinely used laboratory equipment along, while some other sophisticated equipment will be discussed in other chapters.

pH Meter

A pH meter measures exactly the H+ concentration of a solution; thus indicates acidity or alkalinity of a solution with greater precision. Actually, it measures the difference in electrical potential between a pH electrode and a reference electrode, and display the results converted into the corresponding pH value. Electrode is the key part (rod-like structure, usually made of glass) of a pH meter, having a bulb at the bottom containing a sensor. The pH meters range from simple and inexpensive pen-like devices (portable/pocket pH meter) to complex and expensive laboratory instruments with computer interface (Figure 5.1).

Frequent calibration of a pH meter using the solutions of known pH (standard solution of pH 4.01, 7.00, 10.01, Figure 5.2), generally before each use, ensures the accuracy of the instrument. For very precise work the pH meter should be calibrated before each measurement. For normal use calibration should be performed at the beginning of each day. This is necessary because the glass electrode does not give a reproducible measurement over a longer period of time.

Results and discussion: concept Result is the outcome, consequences or conclusion of a problem, probe or experiment organized after a period of time. This conclusion can be one result, multiple results or no result as such. The length of time taken to find a result can vary from less than a second to many years. In this chapter, the result of the Research has been elaborated and also discussed later. The purpose of the discussion/revelation is to interpret and describe the significance of our findings in light of what was already known about the research problem being investigated, and to explain any new understanding or insights about the problem after we have taken the findings into consideration. The discussion will always connect to the introduction by way of the research questions or hypothesis we posed and the literature we reviewed, but it does not simply repeat or rearrange the introduction and the discussion always explain how our study has moved towards the research problem.

Introduction

Seafood undergoes rapid spoilage after capture or harvest due to their highly perishable nature. Spoilage refers to any change that renders seafood unacceptable for human consumption. Spoilage occurs as a consequence of various microbial, biochemical and chemical breakdown processes. Spoilage leads to quality changes in seafood. Quality change refers to any change that occur after harvest due to unpredictable catch, uncontrolled harvest, inadequate handling, processing and storage facilities. The initial quality loss is mainly due to the post-mortem autolytic activity (enzymatic process) and chemical degradation process (lipid oxidation); and later by microbial degradation. The quality problems occur as a result of poor-quality raw material, ice and water, microbiological contamination, presence of heavy metals and other storage aspects during processing.

Processing of fish means preparing raw fish into a marketable form. Pre processing is done prior to final processing. Pre-processing is often done on board fishing vessel or in a shore based plant. It includes operation such as washing, sorting, grading, butchering, etc of the harvested fish. The butchering involves removal of non-edible portions such as viscera, head, tails and fins from fish. The yield of fish meat varies from 30 to 70% depending on the butchering process. Butchering process includes beheading, gutting, filleting, peeling, deveining, shucking, etc. The discarded portion of fish meat are fish wastes, often used for animal feed or for conversion to bioactive functional foods. Final processing of fish includes processes such as heating, freezing, drying, salting, marinading, irradiation, or addition of chemicals. The processed seafood is categorized into five major groups – chilled, frozen, canned, cured and other value-added products in this chapter.

Introduction

The antibiotics are low molecular weight natural, semi-synthetic, or synthetic substance that kills or slows the growth of germs while causing little or no harm to the host is considered an antimicrobial (Walsh, 2000). Antibiotics are the type of medicine produced by some microorganisms that kill or slow the growth of other microorganisms. It includes any of a large group of chemical substances, as penicillin or streptomycin, produced by various microorganisms and fungi, having the capacity in dilute solutions to inhibit the growth of or to destroy bacteria and other microorganisms, used chiefly in the treatment of infectious diseases (De Vetten et al., 2003). However today, a large number of bacteria are resistant to various antibiotics. Antibiotic resistance occurs when a bacterium becomes able to survive and multiply despite the presence of an antibiotic that would normally control or kill it. In other words, the bacteria become “resistant” and continue to grow even at therapeutic levels of the antibiotic. While antibiotic resistance is a natural phenomenon, it is accelerated by the selective pressure exerted when an antibiotic is used. Bacteria that are naturally resistant to the antibiotic have a better chance of survival compared to those that are susceptible. As the susceptible bacteria are killed or inhibited, resistant strains are favored and continue to thrive (Holme et al., 2006). Some resistance arises without human influence, as bacteria can naturally produce antibiotics against other microorganisms, resulting in a low-level, natural selection for antibiotic resistance. However, the current surge in antibiotic resistant bacteria is largely attributed to the overuse and misuse of antibiotics. One of the main issues facing public health is antimicrobial resistance, particularly in developing nations where access to and use of medications are easier than in developed nations, leading to a disproportionately higher rate of inappropriate antibiotic use and higher resistance levels (Ganguly et al., 2011). Antimicrobial resistance will make it more difficult to control infections in the community and make health care services less effective (Bhatia et al., 2010). It is well known that India has one of the highest rates of infectious disease burdens in the world, and that the country’s high rates of malnutrition and inadequate sanitation make these circumstances worse (http://www. resistancestrategies.org/wpcontent/uploads/2011/03/Indiareport).

Introduction

Antimicrobials, viz. antibiotics, antivirals, antifungals and anthelmintics are substances widely used to prevent and treat infections in humans, fish & prawn, livestock animals, and crops. In a situation where microorganisms such as bacteria, viruses, parasites or fungi become resistant to antimicrobial treatments to which they were previously susceptible, it is apprehended that antimicrobial resistance in the microbes has evolved. In fact, antibiotic resistant bacteria evade the effects of antibiotics and multiply in their own way leading to severe health consequences in human and animals. The menace is such that antimicrobial resistance (AMR) hinders treatment modalities targeted for infectious diseases. The hazards of antimicrobial resistance is frequently observed in various pathogenic and non-pathogenic organisms, viz. Salmonella spp., Campylobacter spp., Yersinia sp., E. coli serotype O157:H7, enterococci, Pasteurella sp., Actinobacillus sp. with varying severity (McEwen and Fedorka-Cray, 2002). Microorganisms that develop resistance to commonly used antimicrobials are referred to as superbugs. Globally it is a matter of great concern that it spreads rapidly and threatening the ability to treat common infectious diseases, resulting in prolonged illness, disability and death. Without any effective antimicrobial agent, treatment of infectious diseases, many medical procedures like cancer therapy, diabetes management, organ transplantation, and major surgery will not be possible. The microbes showing resistance to multiple antimicrobials are commonly known as multidrug resistance (MDR) organisms (Magiorakos et al., 2012).

F0 value: It is used to express F-value when z =10oC / 18oF and the temperature is 121.1oC. It is the number of minutes at a specific temperature (250oC) required to destroy or kill a stated number of microorganisms and has specific z-value. It is also called reference value.

Facing or lining board: The layer of the paper on which the flute is embedded is called facing or lining board (Plate 258).

Facultative anaerobic: Organisms that grow either with or without oxygen.

Facultative parasites: Facultative parasites can adapt to live on dead organic matter and often have a wide host range and can easily be cultured on artificial media. These organisms may be aerobic or anaerobic but under changed conditions, they changes to anaerobic or aerobic.

Falling rate period: It is that part of the drying process during which the drying rate varies with time and the instantaneous drying rate per unit surface or weight of dry material continuously decreases. Falling rate takes place when most of the moisture has been evaporated during constant rate period. The falling rate period during dehydration take place in the final stage of dehydration when the food commodities have large amount of free water available for evaporation. Here, rate of removal of the moisture from the food to the surrounding is continuously decreasing / falling per unit time.

Pineapple is a tropical plant with edible multiple fruit consisting of coalesced berries. It is named after pine cone due its resemblance with its structure. It is the most economically important plant in the family of Bromeliaceae. It is widely grown throughout the world for its dual-purpose use in the form of fresh fruit and many processed products. It is a tropical fruit having excellent taste, juiciness, aroma and flavour which is preferred by many people. It is also rich source of fibre, potassium and vitamin C, vitamin B1 and vitamin B6. One of the important constituents in the fruit is proteolytic enzyme bromelein which is known to have significant use in treating conditions like inflammation, sinusitis, arthritis and early recovery from surgery (Joy, 2010). Bromelein is a digestive enzyme also used as meat tenderizer. Pineapple is cultivated in an area of 106.22 thousand ha and total production is 1,527.93 thousand tons (APEDA). Major producing states of pineapple were West Bengal, Assam and Karnataka. Pineapple is highly perishable fruit which transpires heavily and lose moisture thus have high susceptibility to spoilage microorganism (Hossain and Bepary, 2015). There are often several difficulties in production of pineapple with its physiologically active state even after harvest and non climacteric nature. Even though production is more, there are enormous post harvest losses for the fruit. The overall losses being encountered constitute 32.12 percent (6.82% at farm level, 3.09% at wholesale market and transportation, 5.44 % at retail market level, 5.64% during storage, 4.31% in processing unit and 6.82% at consumer level respectively) as reported by Ningobam, (2019).

2.1 Definition and Boundaries of Watershed Areas

Concept of Watershed Boundaries

The concept of watershed boundaries is fundamental to understanding the hydrological and ecological dynamics of a given landscape. Watershed boundaries, also known as drainage divides or catchment areas, delineate the geographical extent of a watershed, which is an area of land where all the water drains to a common outlet, such as a stream, river, lake, or ocean. Watershed boundaries represent the natural hydrological and ecological units of a landscape, reflecting the interconnectedness of water resources and ecosystems. Understanding the factors influencing their definition is essential for effective watershed management, resource planning, and environmental conservation. Exploring the delineation of watershed boundaries involves considering various factors that influence their definition:

a. Topography: Topography, particularly the elevation and slope of the land, plays a significant role in defining watershed boundaries. Watershed boundaries typically follow ridgelines or high points in the landscape, where water flows in different directions, ultimately converging into distinct drainage networks.

b. Hydrology: Hydrological characteristics, such as precipitation patterns, surface runoff, and groundwater flow, influence the delineation of watershed boundaries. Areas with higher rainfall or snowmelt may have larger watersheds with more extensive drainage areas, while areas with low precipitation may have smaller, more localized watersheds.

Organic liquid formulations (OLFs) are agricultural inputs derived from natural sources, designed for use in organic farming. These formulations, consisting of liquid solutions or suspensions containing organic compounds, nutrients, and beneficial microorganisms, play a crucial role in enhancing soil fertility, plant nutrition, and pest management, while promoting environmental sustainability and ecosystem health. Despite their eco friendly nature, OLFs demand careful consideration for their environmental impact and safety. They biodegrade readily, reducing long-term persistence and are less harmful to non-target organisms. While OLFs offer numerous benefits, they also face limitations in potency and effectiveness compared to synthetic pesticides, often requiring more frequent applications and leading to increased labor costs. Their impact can vary with pest species and environmental conditions, and they generally provide gradual rather than immediate pest control. Availability and accessibility can be limited, posing challenges for some farmers. This chapter explores the role of OLFs in achieving success in organic farming, highlighting their benefits and limitations, and emphasizing the importance of Integrated Pest Management strategies and careful consideration of various factors to optimize their use in promoting sustainable agriculture.

The unsustainable, faulty, environmentally detrimental modern agricultural practices and their plausible deleterious effects on one side and challenges like global climate change, ever shrinking land and water resources and loss of biodiversity on the other hand are the main problems that Agriculture is facing. Hence, there is a need to adopt a set of ecofriendly and climate smart practices to achieve sustainable development goals (SDGs). Agroforestry and organic farming (farming without chemicals) are the two important concepts projected to mitigate the effects of climate change, enhance soil health, encourage crop diversification, promoting biodiversity and achieving climate resilience. We made an attempt to synthesize the available information on the role of agroforestry in promotion of organic farming.

1. Introduction

Agroforestry is a land use system that integrates trees, crops and animals in a way that is scientifically sound, ecologically desirable, practically feasible and socially acceptable to the farmers (Nair, 1979). It is a collective name for land use systems and technologies, where woody perennials (trees, shrubs, palms, bamboos, etc.) are deliberately used on the same piece of land management units as agriculture crops and/or animals in some form of spatial arrangement or temporal sequence. It includes both ecological and economical interactions among the different components. Nearly 43% of world’s agricultural land has at least 10% tree cover, which suggests that agroforestry is widespread and infact, it is present in all continents. Agroforestry accounts for nearly 45.4 m-ha globally and 23.25 m-ha of land in India (Rizvi et al., 2019; Anonymous, 2020).

In this chapter, the study’s findings are presented in a structured manner, accompanied by a discussion based on the analysis. The study aimed to present its findings in alignment with its objectives. Towards the end of this chapter, connections between the findings are established, explanations are provided, and an effort is made to uncover the underlying causes. The results and their corresponding discussion are organized according to the specific objectives of the study.

Result: Table 6.1 presents the distribution of 16 independent variables (x1-x16 ) and 3 dependent variables (y1 y3 ) in terms of their Minimum, Maximum, Mean, Variance, Standard deviation, and Coefficient of variation.

According to the study the maximum value for the independent variable Age at survey (x1 ) is 46.00, and minimum is 25.00. The study’s overall distribution was determined to have a mean of 32.938 with a variance of 22.895 and standard deviation 4.785. The high level of consistency is indicated by the variable’s coefficient of variation, which is 14.527%.

According to the study the maximum value for the independent variable Marital status (x2 ) is 18.00 and minimum is 0.00. The study’s overall distribution was determined to have a mean of 3.838 with a variance of 15.783 and standard deviation 3.973. The low level of consistency is indicated by the variable’s coefficient of variation, which is 103.527%.

India is the second largest producer of fruits However, the export potential of fruits and vegetables is very negligible. This is because of improper knowledge to the farmer about proper post-harvest infrastructure facilities. Fruits have a high-water content ranging from 70-95 per cent. They dry quickly under any normal atmospheric condition. These causes loss of rigidity and shrinkage of the cells cause wilting and shrivelling. Appropriate packaging ensures prolonged the shelf life of fruits and vegetables by preventing moisture loss and thereby wilting. Transportation is a critical phase in the fruit supply chain that can significantly affect the quality of fruits. Several factors during transportation can lead to quality degradation such as temperature/humidity fluctuations, mechanical damage, transit time etc. To mitigate the adverse effects of transportation on fruit quality, best practices ie, real-time monitoring, temperature and humidity control, loading/unloading techniques can be employed. Quality evaluation is a critical component in the fruit industry, encompassing a range of assessments to ensure fruits meet the desired standards for consumer satisfaction, shelf life, regulatory compliance, and market competitiveness. It involves a comprehensive approach that includes physical, chemical, and sensory assessments, supported by advanced technological tools, to maintain and enhance the quality of fruits throughout the supply chain. This book chapter deals with the effective packaging, transportation, and quality evaluation of fruits, ensuring that consumers receive fresh, high-quality produce.

Introduction Shrimp aquaculture is a rapidly growing sector worldwide due to transform the intensive cultural practices. The demand for shrimp in the global trade market has increased significantly. The commercially farmed shrimp species, Pacific white leg shrimp, P. vannamei, dominate the market compared to tiger shrimp, P. monodon. Achieving higher shrimp aquaculture production often involves employing high stocking densities and large volumes of feed. This intensification can lead to increased waste and the accumulation of toxic substances, resulting in water pollution, requiring costly management measures to address these issues (Liu et al., 2019; Abakari et al., 2021). Therefore, addressing waste management and water quality concerns is crucial for sustaining the productivity and profitability of shrimp aquaculture operations. In addition to these, several other associated problems – decline in available land resources, escalated environmental pollution, the spread of recurring diseases, the emergence of drug-resistant microorganisms, and the impacts of climate change – with the development of shrimp aquaculture were reported (Santos and Ramos, 2018). To avoid these issues, it is essential to regulate and implement sustainable shrimp aquaculture practices that can be achieved through species and system diversification and environmentally sustainable technologies. Adopting these BFT systems allows for a more sustainable and resilient aquaculture operation (Zhao et al., 2016; 2021).

This chapter is an extensive survey of all past studies relevant to the field of investigation which gives a knowledge of what others have found out in the related f ield of study. In any scientific investigation or research a comprehensive presentation of review of literature is a statutory requirement. Its main functions are to develop a better understanding of the problem to be investigated, delineate a new area of study and avoid unnecessary duplication, decide on the tools and techniques to be adopted including developing some new ones, also to relate the present study with the previous ones by finding out the areas of agreement and disagreement.

The review of literature of the present study is based on the major concepts related to the f ield of investigation. As direct references on all the item are not in abundance, certain specific references along with some indirect references have been incorporated in this chapter for the purpose of meaningful use.

Review of literature has been organized with a view to provide hard evidences as to clinically justify the reasons, logic, and contemplation leading to heuristically infer the different echelons of resilience issues.This is also catered to isolate the apparently less attempted genre of resilience study and analysis. Climate change, uncertainty, decline of soil organic carbon, fatigued genes on land, loss of biodiversity and fragile ecology of society have only been some of myriad of factors causing the loss of resilience, from ecology and from society as well.

Insecticide resistance is a growing concern for those who need insecticides for medical, veterinary, and agricultural control of insect pests. In response to the introduction of DDT resistance in 1947, the incidence of resistance has increased annually by an alarming amount. Resistance is “the inherited ability of a strain of some organism to survive doses of a toxicant that would kill the majority of individuals in a normal population of the same species” (WHO, 1957).

As a result of continued insecticide application, the proportion of resistant insects increases compared to that of susceptible and the population becomes increasingly difficult to control

Above photograph theoretical example illustrating the increase of insecticide resistance levels in a pest population. Some individuals (black) with genetic traits allowing them to survive insecticide applications can reproduce; if the selection pressure is frequent, they easily become the preponderant part of the population (Fig. 1).

An adaptation to a pesticide leads to reduced susceptibility to it among the pest population targeted by that pesticide. In nature, pests develop resistance to chemicals through natural selection. In the most resistant organisms, their genetic traits are passed on to their descendants. Since 1945, at least 500 species of pests have developed resistance to pesticides (Anonymous, 2007), but other sources estimate as many as 1000 species (Miller, 2004).

A management tool for anticipating the onset of diseases in plants is called plant disease forecasting. This management method makes use of data on the past, present, and predicted weather in a particular area to forecast the onset and severity of disease in the future. In this sense, a plant disease forecasting system notifies farmers ahead of time whether or not to modify their crop protection strategies to ward against pests. The disease forecasting method lowers financial costs, farmer production loss, and negative environmental effects when it is timely and precisely forecasted. These systems ought to be prepared for diseases like these, which don’t happen often but rather manifest destructively during opportune weather.

Requirements for Disease Forecasting

Systems for forecasting plant diseases are based on the “disease triangle,” which describes how the environment, host, and pathogen interact. Therefore, information on these variables is necessary for the accurate forecasting of a disease outbreak in the future. Following questions and answers cover various aspects of disease forecasting and pathometry, including their impact on integrated disease management, environmental considerations, and specific challenges in different agricultural settings.

The pandemic in 2019-2022 spread swiftly and became global in no time, caused by SARS-CoV-2. Vaccines were rapidly developed against the virus to restore public health and save global economy. Vaccines for immunisation drives were developed in a year of the pandemic becoming global and approved for ‘emergency use’ following expeditious development protocols. Vaccine development employed numerous nucleic acid, adenovirus and protein-based state-of-art molecular platforms, alongside the conventional attenuated and inactivated virus approaches. The majority of the attempts were successful and approved for use. All the approved vaccines were found safe and effective as per Phase I through Phase III clinical trials’ results. Mass immunisation drives demonstrably led to reduced hospitalisation, low disease severity and less mortality. Yet, there were initial vaccination hesitation across the world due to associated safety concerns about its possible long-term negative consequences. A part of it was attributed to technical reasons (as clinical trials were not fully complete with sturdy and convincing outcomes), and a majority was due to the misinformation that floated on the social media and other digital communications. Vaccine deployment across the globe was far from being equitable. Thus, immunisation was rapid in higher income (developed) nations with access to innovative advanced vaccines while low immunisation rates were seen in the low- and medium-income countries accessing majorly the vaccines based on simple technology. Given the scale and spread of the pandemic, scaled-up vaccine production and equitable distribution to limit viral spread and improve global health and socioeconomy were critical. This chapter attempts to dissect these scenarios and lessons learnt from these to prepare better for any such pandemic in future.

1. Forecasting Rain and Frost

i. Behavior of Ants and Goats:

• Ants: When ants come out of their nest carrying their pupae, it indicates that rain will come soon.

• Goats: Goats can sense approaching rain and signal it 2 to 3 days in advance through behavioral changes. They change their usual resting places, show little interest in taking food or water, and bawl and shout throughout the day.

6.2 Introduction

Correlation is a fundamental statistical concept that measures the degree of association or relationship between two or more variables. Correlation helps us to understand how changes in one variable correspond to changes in another. Correlation values range from -1 to 1; where -1 indicates a perfect negative correlation, +1 represents a perfect positive correlation and 0 suggests no linear correlation between the variables. The sign and magnitude of the correlation coefficient provide information about the strength and direction of the relationship between the variables. Correlation analysis is a multipurpose tool with various applications, such as identifying the strength of relationships between stock prices and market indices, assessing the impact of education on income levels, or determining the association between weather conditions and crop yields. Understanding correlation is essential for making informed decisions, drawing conclusions from data, and developing predictive models in numerous fields of study and practice.

Introduction
Plantation crops are high-value industrial crops grown in the tropics and coastal areas. They have great potential for utilization of wasteland like rainfed dry land, hilly, arid, and coastal areas to provide nutritional security; earn foreign exchange, and ensure livelihood security. The major plantation crops grown in India are tea (Camellia sinensis L), coffee (Coffea arabica L.), rubber (Havea brasiliensis), coconut (Cocos nucifera), areca nut (Areca catechu L.), oil palm (Elaeis guinensis), cashew nut (Anacardium occidentale L.) and cocoa (Theobroma cacao L.). India is the leading producer of most of
these plantation crops. Among all fruit crops, processing plays an important role in plantation crops as they are generally consumed only after processing. In addition to primary products, some by-products from these crops also have various commercial uses. Coconut, areca nut, cashew nut, black pepper, and cardamom are known as smallholder plantations whereas, crops like rubber, tea, and coffee are known as estate crops or conventional plantation crops. Processing aspects of some of these crops are discussed here:

Abstract
Every nation needs an effective food legislation and food control service to promote a safe, honestly presented food supply, and to protect consumers from contaminated, adulterated, and spoiled foods. The principles to be included in food safety and legislations are primarily inspection, enforcement, biological and chemical contaminants, packaging and labelling, and food trade in local and overseas market. Harmonization of Food Law on the international level is a worldwide trend from the late twentieth century. In India AGMARK and FSSAI are sole regulatory authority for food production and marketing. International laws and regulations play a vital role in trade and commerce. International regulatory bodies include CODEX, EU, HALAL, USFDA, FAO and WTO. This chapter deals with international and national food safety regulation and legislations with regulatory framework in India and implications on international trade.

Economics revolves around key concepts such as goods value, price, wealth, income, savings, investment, and consumption. These concepts are interconnected and form the foundation of economic analysis. Below is a detailed explanation of each:
Goods: Definition, Types, and Economic Importance
Definition of Goods
Goods refer to tangible or intangible items that satisfy human wants and have value. Goods can be material (physical objects) or non-material (services), and they play a crucial role in fulfilling human needs and desires. They form the basis of economic activity, as humans constantly seek to fulfil their needs and desires.
Examples
Tangible Goods: You can touch them. Food, clothing, vehicles, dairy products. Intangible Goods (Services): Services you experience. Veterinary services, teaching, medical care.
Classification of Goods in Economics
Goods can be categorized based on different criteria such as material nature, supply, transferability, consumption, ownership, and income elasticity.

Haemostasis refers to the physiological process that prevents blood loss following vascular injury while maintaining fluid blood flow within the vascular system. It involves a complex interplay between the vascular endothelium, platelets, coagulation factors, and fibrinolytic proteins. In animals, laboratory tests for haemostasis play a critical role in diagnosing bleeding disorders, monitoring treatment, and investigating hypercoagulable states. This article discusses the principles, applications, and limitations of laboratory tests used to assess haemostasis in animals.
In veterinary medicine, laboratory tests for haemostasis are essential diagnostic tools for identifying bleeding disorders, hypercoagulable states, and monitoring therapeutic interventions. They are crucial in both emergency and routine clinical settings for animals. These tests provide insights into the functionality of primary haemostasis (platelet plug formation), secondary haemostasis (coagulation cascade and fibrin clot formation), and tertiary haemostasis (fibrinolysis and clot breakdown).

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).

Introduction
Teleost fish, the largest group of vertebrates, comprise about 30,000 species on Earth, while shellfish include over a million species (Nelson, 2006). About 400 of them have been cultivated, according to Gjedrem and Robinson (2014). One of the most environmentally friendly ways that people may get protein is through fish farming. Over the past few decades, aquaculture has grown rapidly among all agricultural sectors. Fish aquaculture, however, is confronted with several significant obstacles. Most cultivated species have not undergone genetic modification through breeding and are still in their natural state. Although there are a few species-specific feeds, most farmed species do not have tailored diets. Pathogens such as bacteria, parasites, and viruses lead to various fish diseases, resulting in significant financial losses in aquaculture (Meyer and Schnick 1989). Diseases caused aquaculture to lose billions of dollars annually in revenue worldwide. Aquaculture has had
significant issues due to aquatic toxicants (Dunier and Siwicki 1993), which has led to environmental problems in the aquaculture sector (Cao et al., 2007). Innovative solutions and technology are needed to address these issues to make aquaculture advantageous and sustainable.

1.1 Carbohydrates Biochemistry
Carbohydrates are essential for life, both in plants and in animals. They are organic chemical compounds made of C, H, and O. These elements get arranged in different ways so that several simple, and stored complex compounds (starch in plants and glycogen in animals) are available in abundance on the Earth. They are involved in enormous biological and nonbiological functions. Their biological functions, found in all living things, are the chief energy source for men and animals, even for herbivorous fishlike carp and rohu fingerlings. Carbohydrates are also essential structural components like nucleic acids, containing genetic information. One must recognize the protective function in cells, plants, and human health management. Even bacteria form a glycocalyx and biofilm for protection. Knowledge about their involvement in blood groups helped to identify universal donors, universal recipients, and genuine donors for the recipient to save a life. Carbohydrates are found as a storage structure for energy in emergency conditions.
Upon combustion, they yield carbon dioxide and water. Autotrophs (plants) synthesize them from carbon dioxide and water to grow, reproduce, and store, but heterotrophs (humans and other animals) use them, too. In plants, they occur as fibers, supporting structures, and simple sugars. The plant carbohydrates are used for preparing adhesives, fermentation, foods, and papers. Cotton fibers are used to make clothes to cover the body and protect humans and animals against adverse climatic conditions.

    Introduction
Over 60% of the population in India is occupied in agriculture and associated fields, making it one of the world’s most agriculturally dense nations. In India, the agricultural sector accounts for 18.6% of the country’s GDP. Almost all crops, including cereals, vegetables, and cash crops, are grown in India (Vanitha et al., 2013; APEDA, 2020). From the beginning of time, several pests, including weeds, insects, plant diseases, and nematodes, have had a detrimental effect on agriculture. As a result, crop losses are estimated to be 45%, or over 290 billion, annually (Aneja et al., 2016). Regardless of tactics, illnesses and pests significantly contribute to agricultural losses. Diseases, weeds, and insects hinder plant growth and lower plant density, eventually lowering the food supply. The Entomological Society of America (ESA) has released a policy statement stating that invasive insects cost more than $2.5 billion to control and cost $18 billion per year in economic losses to pastures, crops, lawns, and forests (The Not-So-Hidden Dangers of Invasive Species, 2018). Invasive crop pests continue to threaten food security because of the intricate relationships between human migration, international trade, climate change, and evolving agricultural techniques. Several of these variables also contribute to the sharp rise of urban pests and disease-carrying insects. The primary method of insect pest management has been chemical pesticides. Nonetheless, an increasing call for less agricultural chemical use due to worries about the environment, human health, and pesticide resistance ignites interest in novel ways.
Conventional chemical pesticides have raised food production and harmed non-target animals and the ecosystem. To prevent and mitigate pest-induced crop losses in storage (post-harvest losses) and in the field (pre-harvest losses). This has been accomplished through the development of numerous crop protection techniques. In the past few decades, chemical pesticides have been utilized to reduce food losses induced by insect pests; however, this has decreased agricultural production. Moreover, volatile pesticide residues have periodically raised questions about food safety among domestic customers and presented challenges to export crops’ ability to trade. Insecticides can cause physical or biological harm to pests. Certain insecticides are applied topically or indirectly to plants those insects may consume. Pesticides harm nature, soil, and human well-being, so regulations and rules governing their use are becoming more stringent. New technology and products to control and prevent pests are desperately needed. In modern agriculture, various methods are now available, including biological control, insect behavior, genetic modification, microbial pesticides and plant immunization of pest populations.

Migration reflects the patterns of societal transformations. From a historical perspective, throughout the process of industrialization and economic advancement, individuals relocate from agricultural areas to industrial sectors, from rural areas to urban centres, from one urban centre to another, and from one nation to another. Currently, Asia, Africa, and Latin America are seeing significant technical advancements, leading to a substantial movement from rural to urban areas in these countries. Economists research migration because to its impact on the availability of skilled and semi-skilled workers, the growth of industries and commerce, and the resulting changes in the employment patterns of migrants. The formulation of economic policy is closely intertwined with the phenomenon of migration, since migration significantly impacts a country’s economic and social progress. The study of migration is crucial due to its impact on population dynamics, including population size, growth rate, and demographic structure, as determined by birth rate, death rate, and migration. Furthermore, migration significantly influences the geographical spread of the population and the availability of workforce inside the nation. Therefore, the analysis of occupational migration is valuable in developing economic and other governmental policies, as well as informing the work of economists, sociologists, legislators, planners, and demographers
Current ideas on labour migration
Overview
Since ancient times, humans have struggled to meet their fundamental needs for food, housing, and other necessities. They naturally gravitate toward personal development. Human life has always involved migration in one form or another. believes that migration is a permanent or semi-permanent shift in residence, regardless of the length of the journey (Lee, 1966). People have been moving throughout the world for a variety of reasons since prehistoric times, both within and between regions. In the past, geographical elements such the atmosphere, soil fertility, native vegetation, etc., had a major impact

1. Introduction
Studies on soil health and agricultural growth are increasingly using artificial intelligence (AI) and machine learning (ML) techniques. With the help of these technologies, it is possible to analyse vast amounts of data and gain insightful knowledge that will help to boost crop yields and optimise agricultural practises (Neethirajan, 2020). Applications of AI and ML to research crop development and soil health have enormous potential to revolutionise agriculture. In order to increase soil health and crop yield, farmers and researchers can use these technologies to analyse massive datasets, generate precise forecasts, and optimise farming practises. Overall, artificial intelligence (AI) and machine learning (ML) provide useful tools that can support efficient and sustainable agriculture, solving global concerns in food availability and the sustainability of the environment. Unquestionably, technical developments have significantly increased the productivity and efficiency of many industries, including agriculture. The advent of words like “big data,” “data analytics,” “artificial intelligence,” “Internet of Things,” “erosion modelling,” “smart farming,” and “machine learning” are just a few examples of this technological revolution (Almoussawi et al., 2022). Digital soil mapping (DSM) uses computational models to infer regional and temporal shifts of soil types and properties based on soil observations, prior knowledge, and relevant environmental variables in order to create and populate spatial soil information systems. The supply chain for agricultural production is extremely intricate (Lamichhane et al., 2019). The way our food is produced, distributed, and consumed is changing as a result of AI. When planning crop rotations, planting times, water and nutrient management, pest and disease control, optimal harvesting, food marketing, product distribution, food safety, and other agriculture-related tasks throughout every step of the food supply chain, researchers use powered by AI tools to supply advice and expertise. In “Harnessing AI to transform agriculture and inform agricultural research,” Peters et al. (2020) presented a summary of the most recent developments, difficulties, and prospects for AI technology in agriculture. They use the four main elements of the food system—production, distribution, consumption, and uncertainty—to show the possibilities of AI. They come to the conclusion that agricultural businesses are excellent candidates for using AI and other technologies. In “AI down on the farm,” Sudduth et al. (2020), examined a number of case studies in which machine learning (ML) has been used to model various aspects of agricultural production systems and give data that can be utilised to make management decisions at the farm level. These research efforts involve providing data, essential for creating precise and effective irrigation systems and improving tools for suggesting the best nitrogen fertilisation rates for maize. Traditional crop health monitoring techniques need a lot of work and time. Using AI to monitor and detect potential crop problems or nutrient deficits in the soil is an effective method. Applications to analyse plant health trends in agriculture are being created with the aid of deep learning. These AI-powered tools are essential for improving our understanding of soil quality, crop pests, and disease in plants (Virnodkar et al., 2020).

Introduction
Definition of heterosis
The word “heterosis” was coined by G.H. Shull in 1914 as a convenient abbreviation for awkward phrases like ‘stimulation of heterozygosis’. When two genetically diverse parents are crossed, the resulting F1 or hybrid progeny has superior performance over both of its parents which is known as heterosis. The F1 or hybrid has superiority in vigour, adaptability, stress tolerance, growth rate, population fitness, biological and economic yield. Luxuriance on the other hand is a more general term often confused with heterosis, used to describe plant’s overall healthy and abundant growth, regardless of its genetic background (Allard, 1960). Charles Darwin introduced the concept of hybrid vigour in 1876, a term closely related to heterosis. The exceptional hybrid vigour in the F1 generation stems from the theory of dominance and codominance, offering numerous advantageous characteristics, particularly economically significant ones.
Heterosis is confined to F1 or hybrid generation only. The F2 and subsequent generations do not show heterosis due to factors like recombination and segregation, which lead to shuffling of the genes and produce variety of new combinations, hence they are neither homogenous like F1 nor have hybrid vigour. One of the main characteristics of heterosis is that it is highly variable from crop to crop as well as from cross to cross. So, some of the crosses will exhibit higher heterosis than the other crosses. This is because heterosis is controlled by many factors which include the genetic diversity of parents, combining ability of parental lines, genetic background, additive, dominance, epistasis nature of gene imparting heterosis which will be dealt in detail in next sections of the book.
Heterosis, manifested in positive (yield, quality, disease resistance) or negative (plant height, maturity duration) aspects, is more prevalent in crosspollinated species than in self-pollinated ones. It can be fully exploited in hybrids or partially exploited in synthetic and composite varieties. The performance of hybrids relative to parents exhibits distinct features, as illustrated in Figure 1, including better-parent heterosis with optimal trait values surpassing either parent. Mid-parent heterosis exceeds the parental average but holds limited agronomic relevance. Phenotypes are broadly categorized as additive (similar to parental average) or non-additive, further subdivided into partially dominant, dominant, and over/under dominant. Factors influencing heterosis include genetic diversity, combining ability, genetic background, and the interplay of additive, dominance, and epistatic genetic factors, explored in detail in subsequent sections.

Organic Agriculture
Organic and biodynamic farming use natural methods to grow crops, avoiding inorganic fertilizers, pesticides, and other chemicals throughout the growth stages. This approach relies on natural biological systems, preserving their relationships and self-regulation, unlike conventional farming, which heavily depends on synthetic inputs. As a result, plant and animal varieties bred for intensive agriculture often do not align with organic principles. To unlock the full potential of organic farming, genetics of seeds should also be organic, ideally bred and grown exclusively in organic conditions to best suit these systems.
Organic plant breeding
Improving the genetic diversity of the crops and their adaptation to the future organic growing conditions and climate change need to be done through organic plant breeding. The choice of varieties for organic farming that are mostly derived from conventional bred varieties, sustainable use of natural input resources and at the dynamic equilibrium of the entire agro ecosystem are the main features. The organic breeding programs should match with the reproduction system of the respective crop. Seeds and vegetatively propagated crops are important resources for organic breeding. The Organic agriculture system relies on natural inputs and pesticide free and non GMO crops, vegetable and fruits aiming providing healthy food. In an overall manner, organic agriculture is the expression of underlying ecology, fairness and health. Organic agriculture is presently practiced in organically converted and managed land area equal to 2% of the cultivated area in India.
International Federations of Organic Agriculture Movement (IFOAM) (2015 and 2017): Organic agriculture is defined as a production system that sustains the soil health, ecosystem and people. It relies on ecological processes, bio diversity, and local conditions. Organic farming is part of organic agriculture and it is basically based on the underlying principles of health, fairness, ecology and care. The well-known characteristic of organic farming is, it produces food without the use of any synthetic fertilizer or pesticides and also without the use of GMO. Trends and perspectives in organic plant breeding are recognized as a highly collaborative and possess strong interrelationships.

Animals experience the effects of force in everyday life. For example, the animal body exerts a force on the body and to the objects during various agricultural operations. Furthermore, the gravitational force exerts continuously, for instance while sitting, walking, etc. All parts of the body in one way or the other are loaded by forces. The bones provide rigidity to the body and can sustain high loads. The skin is resistant to force. The cardiovascular system is continuously loaded dynamically owing to the pulsating blood pressure. The bladder is loaded and stretched when it fills up. The intervertebral discs serve as flexible force- transmitting media that give the spine its flexibility. Beside force, animals are using levers all the time in their daily life to increase the ‘force’ that is applied to some object.
Animal soft tissues are complex materials that can exhibit nonlinear, time dependent, inhomogeneous, and anisotropic behaviors. The mechanical responses are reflected in all levels of organism (molecules, organelle and body levels). Several biological activities are under the action of forces, which even govern the gene expression. The study dealing with the forces and their effects on living systems is the Biomechanics.
Biomechanics applies the laws and the techniques of mechanics in the study of biological systems and phenomena. Indeed, mechanics provides the tools for:
