The contribution of dairy sector in the Indian economy has tremendous impact on the country’s GDP. India being the world’s highest milk producing country, dairy industry has a major role in changing the twin problem of the nation that is poverty and unemployment. Dairy sector also involves the under privileged group, especially the dairy farm women. There are many success stories regarding the life changing experiences gained by the farm women, who had taken dairy farming as a means to sustain their livelihood. In the area of gender equality, dairy sector has proved to be a women centric enterprise. Most of the activities pertaining to dairy farming are mostly carried out by the farm women. The dairy farming activities carried out by the farm women are tedious and in major cases their contribution remains unnoticed. They are usually carrying out activities, where most of their energy is drained, resulting in drudgery. Matters related to decision making, their opinion about adopting new technologies, starting an enterprise are not given importance by their family members. This leads to a greater setback in the emergence of success of dairy sector. Therefore, empowerment of farm women in dairy sector is one of the important criteria for the dairy industry to reach a greater height and for overall development of nation.

Agriculture is the main stay of Indian economy as more than 70 per cent of the people of India are dependent upon this avocation and allied disciplines for their livelihood. Even today, at the dawn of 21st century, the Indian agriculture has continued to be the backbone of our national economy, representing country’s one third of Gross Domestic Product (GDP). Thus, farming families consisting of men, women, boys and girls known as the pillars of our agriculture, constitute backbone of the nation. The support and contributions made by the rural women in agriculture, constituting 55-66 percent of farm work force (Singh et al., 2012) are, however, not less than those performed by the men, and therefore they become spine of the rural economy. In fact, women’s role in the economy has been underestimated and their work in agriculture has long been invisible and unappreciated, if we compare the women’s work participation rate of some of the selected countries like Indonesia, Bangladesh, China. Pakistan and Sri Lanka, we find that India ranks second in position (22.7 %) after Indonesia (33.4%).

Introduction

The Indian literature viz; Vedas and other related books show that ancient Indians used to impart great significance to the gardens and parks. Indian rulers especially, the kings, the princess vis-a-vis affluent people took special interest in making vegetable gardens in the houses and fruit tree gardens in open areas. In those days, it was considered to be the foremost duty of a king to maintain the beautiful gardens in the city and around his palace. It is even said that only he should be revered as an ideal king whose abode is provided with spacious gardens having full of fruit bearing trees (Krishna murthy 2012). As a matter of fact, the gardens also contained pools and tanks adorned with beautiful lotus blossoms, having a number of plants and bushes laden with large number of fragrant flowers etc. Kautilya has included gardens and fields under the term of “Vastu”. So Vastu Sastra or the science of habitation may be taken to stand for laying out of gardens etc; including both horticulture and agriculture.

Genomics is the study of whole genomes of organisms, it uses a combination of DNA sequencing methods, bioinformatics to sequence, assemble, analyse the structure and function of genomes. In another words, it can be defined as it is the study of the structure, function, and inheritance of the genome of an organism. Moreover, genomics focuses on interactions between loci and alleles within the genome and other interactions such as epistasis, pleiotropy and heterosis. Genomics is divided into two basic areas: structural genomics, characterizing the physical nature of whole genomes; and functional genomics, characterizing the transcriptome (the entire range of transcripts produced by a given organism) and the proteome (the entire array of encoded proteins).

Most biological traits are controlled by a large number of genes, which, in addition to their additive effects, may interact with each other, and their expression might be altered based on a variety of environmental effects. Researchers who were among the first to use molecular genetics to the study of cattle began by employing DNA markers to locate genes or sections of the genome affecting features of interest. For instance, identifying a group of genes based on Genome wide association study (GWAS) provides evidence that a causal relationship between a phenotype and a single nucleotide polymorphisms (SNPs) may exist. These findings of GWAS, however, do not improve our understanding of complex traits in which many pathways may be involved. The growing use of genotyping technologies has generated a large quantity of genomic information on the dairy population. Since the draft sequence of the bovine genome was published in 2009 (Zimin et al., 2009), whole-genome sequence data of cattle have also become available.

Introduction

The expanding number of people around the world necessitates an increase in the amount of food that is yielded. As stated by the Food and Agriculture Organization of the United Nations (FAO), global food production ought to be ramped up by a factor of two in the next few years in to meet the requirements of the growing global population in terms of consumption (FAO, 2006). This is because the global population is expected to continue growing at a rate of approximately one person every two seconds until the year 2050. It is possible that the predicted production disparity could be filled by making improvements in genetics, animal health, and the excellence of animal husbandry.

The production of animals has expanded significantly over the course of the last several decades as a direct result of the application of quantitative genetics in animal breeding. However, due to technological limitations, the use of genetic markers in breeding programmes has only been implemented to a relatively small extent (Deng et al., 2016). The concept of genomic prediction, which was first introduced approximately twenty years ago, has completely transformed the planning and execution of animal breeding operations.

Introduction

The key factor of sustainability in the animal sector depends upon genetic improvement in domestic livestock. There are many reproductive and molecular biotechnologies used for the genetic improvement of domestic livestock and they are synergistically coupled with the breeding program in distinct breeding targets. With the help of gene editing techniques (e.g. CRISPR etc.). To improve the specific traits of interest scientists can add, delete or replace the nucleotides (e.g. milk production, meat production, disease resistance, etc.) in less than one generation. Gene editing with the conventional breeding program in livestock is an important factor for genetic improvement for increasing the rate of genetic gain. In the present topic, here, we delved into the most important reproductive and molecular technologies used in livestock genetic improvement, as well as the most effective ways for incorporating gene editing into existing genetic improvement programmes and targeting specific traits for enhancement. The improvement in genetic level is a most powerful part of sustainable animal development because it is permanent and the effects are long-lasting and cumulative. Genetic advancements produced in one generation are passed on to the following, unlike dietary and animal health treatments, which are a continuous process. The many livestock operations that involve chemical and mechanical methods such as dehorning requires time, worker, money, animal safety, etc., but their genetic alternation of the concerned gene for the polled or hornless condition can exclude the requirement of physical dehorning. (Gottardo et al. 2011; Tompson et al. 2017).

Introduction

Wool which obtained primarily from sheep is an essential textile fiber that is used across the world. Whether for clothing, canvas work, carpets, or even upholstery, wool is a vital resource supporting many industries and occupations. This natural fiber has many benefits, such as being biodegradable, easy to clean and even having a natural structure that traps air which is excellent for heat retention. The annual wool production is 2 million tones. China ranks first in terms of global wool production. With a production of more than 333,624 tonnes of wool in 2020, China accounts for approximately 19% of the global wool clip. Australia produces 16% of global wool and is by far the largest wool exporter in the world. There has been a constant increase in the demand of wool products worldwide. This has made scientists to try to improve livestock and livestock associated derivatives. The conventional system along with the recent biotechnological interventions will be helpful for enhancing wool quality and production.

Origin of Insects

Insects are highly specialized group of invertebrates belonging to the largest animal Phyla, the ARTHROPODA, which also includes in it, the prawns, crabs, lobsters, centipedes, millipedes, scorpions, ticks, mites and spiders. Practically three fourth of the animal species come under this phylum.

The Arthropods evolved during Cambrian period from primitive annelidan ancestor. The main evolutionary stem of Arthropod is represented by the Crustacia- Insecta- Myriapoda.

The insects originated in the Devonian period of Palaeozoic era. Diplura and Thysanura are the most primitive wingless insects while mayflies, damselflies, dragonflies and stoneflies represent the primitive winged insects.

Evolution

Evolution is a process whereby population are altered over a period of time and may split into separate branches, hybridize together or terminate by extinction.

Man has tendency to classify everything in a hierarchical manner for example, ships may be classified on size, weight, what they carry or naval versus merchant or passenger. Any of these classification is as valid as any other.

But classification of biological species is unusual in that a predefined system exists i.e. the evolutionary relationships among organisms. But evolutionary relationships can only be estimated; and contrary to popular belief, even a good fossil record does not conclusively show the phylogeny or evolutionary tree of a group species.

Numerical taxonomy can be defined as “Numerical evaluation of the affinity or similarity between taxonomic units and ordering of these units into taxa on the basis of their affinities”. The term includes drawing of phylogenetic inferences from the data by statistical or other mathematical methods to the extent to which this should prove possible. The practice involves a number of fundamental assumptions and philosophical attitudes toward taxonomic work.

The Species Concept in Systematics

The modern biological or, more strictly, genetical concept of a species is a group of interbreeding organisms, genetically isolated from other such groups. The definition of the category species has long been one of the major problems of taxonomy. It is because of two reasons:

1. Because of the congruity of lingering typological concepts with the nature of evolving species.

2. Because evolutionary species may have changing characters and are only gradually differentiated in phylogeny.

For evolutionary study and descriptive purposes, many kinds of variation within species come in to consideration, but the only regular intra specific taxon is the subspecies. Subspecies are widely but not universally useful and their definitions yield to the same sort of criteria as for dividing other phylogentic continuance.

Identification of the insects is the integral part of systematics. It utilises all taxonomic procedures. The collections in the world are the accumulation of past taxonomists and are stored for the future identifications. Every species name is based on a published description or figure and usually on the type specimen. Identification is the association of other specimens with the appropriate description or with type specimen.

The steps in identification are as follows:

1. Preliminary key to orders and families

2. Key to genera and species if recent monographs or faunal works are available

3. Reference to the most recent catalogues

4. Reference to current bibliographies for literature published subsequent to the most recent catalogues

5. Reference to original descriptions

6. Comparison with the authentic described specimens or with types.

Introduction

Virtual supply chain management is the digital representation of inventory data that the managers manage from anywhere in the world. In the 1980s, when the proliferation of computers gave more importance to the human resource, f inance, and manufacturing units communicating with each other for better quality work, that led to enterprise resource planning, and slowly each task of supply chain management started virtualizing in its full length.

A virtual supply chain has advantages such as better inventory control, shorter lead times, quicker order fulfilment, increased supply chain visibility, more accurate demand forecasts, and higher customer satisfaction. It gives businesses the ability to make the most use of their resources, cut expenses and lessen waste throughout the supply chain.

However, putting in place a virtual supply chain calls for thorough planning technology integration, and network-wide process alignment. Overcoming obstacles like data security, interoperability, and change management are all part of it. To fully reap the rewards of a virtual supply chain, businesses must also invest in technical infrastructure, training courses, and partnerships.

14.1 NEED FOR ANIMAL DISEASE INFORMATION SYSTEMS

Once the animal disease data are gathered, a few things need to be done with the data so collected. First, they must be managed and quality checked; Secondly, they must be analyzed to be understandable; and thirdly, they must be acted upon. For data to be analyzable and useful for decision-making, they need cautious management and quality control. An information system is the collection of data, people, procedures, hardware, software, files, and data required to accomplish an organized set of functions.

The constituents of an information system are:

• People – those who gather data, those responsible for data input and those responsible for data analysis

• A storage / retrieval / analysis system – which consists of computer hardware and appropriate software

• A feedback delivery system – mechanisms to ensure that processed data are fed back to data gatherers

Opportunities

India is home to largest milch animal population, totalling around 100 million cattle and buffalo (out of total population of 300 million) spread over 6.5 million census villages. India is the largest milk producer with CAGR of 4.5%, likely to go up to 5%, which is likely to create around 20 million jobs every year. The most significant factor is that dairy industry is likely to exceed IT industry in employment generation. In year 2018, India produced 146 million tonnes of milk contributing 26% of the agriculture GDP.

But the foundation of dairy industry is economically vulnerable as per animal productivity and fertility are very low leading to meagre profits and frequent demands to enhance procurement price. National schemes like Operation Flood, National Dairy Plan-I and National Dairy Plan II, largely focussed on milk collection, processing, distribution and organising farmers but the animal component has been neglected. Enhancing per animal productivity by empowering farmers to scientific management and breeding to achieve genetic improvement needs urgent attention. Although numerous technologies to improve health and genetics are available but the single most important gap is failure to deliver these to farmers. Unlike western world, India has not been able to develop modern veterinary service delivery models. In order to cater to breeding and health services of cattle and buffalo (300 million in numbers) and also pet animals in rural areas and small towns, huge manpower and infrastructure will be required.

Being polytocous animal, sow give birth several (8-14) piglets in each farrowing, mother pig find several deficiencies and disorders during gestation, farrowing and postnatal conditions. Prior to birth intrauterine competition amongst the feotus piglets for nutrition and gas exchange is a big stress for abortion. Several infectious and non-infectious causes may hamper proper growth and pathological conditions resulting mortality (15-20%) in piglets than weaner and adults (Sarma, et al, 2012). Several risk factors are also responsible for piglet mortality.

Prenatal factors: Insults during pregnancy can impact a piglet’s ability to survive after birth and regulate their body temperature. Some maternal aspects that affect survability and mortality amongst piglets are prolong farrowing duration more than 4 hours, number of parity of sow, usually first and second parity show high mortality than subsequent parities and also older sow lose more piglets.

Introduction

Climate change, a global phenomenon of present time, has emerged as the greatest challenge of the world in the twenty-first century. Rising earth’s surface temperature is one of the most threatening factors coming into view. The substantial changes in the earth’s climate have an impact on ecosystems, economics and societies in a variety of ways (Sharma et al., 2024). It is one of the important environmental, agricultural, human and animal health issue. Climate change is an association of multidimensional effects involving physical characteristics, causes and consequences (Visschers, 2018). The climate change has resulted in to increasing global average temperature of air and ocean, melting of snow, rising of ocean level, change in the rainfall pattern and extreme whether events such as drought, flood, heat waves, storms etc.

Tissue Doppler Imaging

Doppler echocardiography relies on detection of the shift in frequency of ultrasound signals reflected from moving objects. With this principle, conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low amplitude signals from small, fast-moving blood cells. In TDI, the same Doppler principles are used to quantify the higher-amplitude, lower-velocity signals of myocardial tissue motion.

There are important limitations to TD interrogation. As with all Doppler techniques, TDI measures only the vector of motion that is parallel to the direction of the ultrasound beam. In addition, TDI measures absolute tissue velocity and is unable to discriminate passive motion (related to translation or tethering) from active motion (fiber shortening or lengthening). The emerging technology of Doppler strain imaging provides a means to differentiate true contractility from passive myocardial motion by looking at relative changes in tissue velocity.

Precision medicine and personalised treatment of systemic or tumour diseases gain their acceptance and application in veterinary care, too. The application of personalised medical protocols and companion diagnostics is easier and ethically well reasoned within the veterinary medical field – and it can offer many advantageous lessons to human clinical transformation, too [1]. In vitro companion diagnostics for testing the applicability and sensitivity levels of certain kinase inhibitor and immunotherapeutic drugs offer a greatly increased efficiency for veterinary cancer patients, too. As the understanding of cancer biology has advanced, the field of veterinary oncology has grown significantly, paralleling developments in human oncology. Precision medicine is an innovative approach to disease treatment and prevention that considers individual variability in genes, environment, and lifestyle. In the context of veterinary medicine, precision medicine aims to provide tailored therapies that are specifically designed for the unique genetic and molecular profile of each animal’s cancer. This approach moves away from the traditional “one-size-fits-all” model, instead focusing on targeted treatments that maximize efficacy while minimizing side effects. Companion diagnostics, such as molecular tests, help determine whether a dog or cat is likely to respond to a particular drug. For dogs and cats, precision medicine holds great promise in improving outcomes for cancers, which are among the leading causes of death in companion animals.

As the heart diseases in companion animals is becoming common as in humans, the research in canine cardiac diseases is one of the most extensive studies in the present scenario. As per the available literature, the overall occurrence of various cardiac abnormalities ranges from 0.37 percent to 1.67 percent in various parts of the country. Whereas, in western parts of the globe, nearly 8 million dogs suffer from heart disease accounting 10% of all dogs in the United States. Heart diseases are common among older dogs; up to 75% of senior dogs have some type of heart condition, and unfortunately, most go undiagnosed due to varied reasons. The recognition of canine cardiac diseases has been delayed, and ignored on account of lack of awareness and knowledge by the owner and inadequate diagnostic facility in our country. Physical examination, radiography, electrocardiography and echocardiography are most useful diagnostic procedures employed in diagnosing the cardiac diseases in dogs. However, majority of the acquired cardiac diseases are being managed medically with one or a combination of drugs. Improved diet management and health care of companion animals have led to increased life expectancy, as a result, cardiac diseases have become pivotal causes of death for both dogs and cats. For such reason, a major objective has become to increase the quality of life by reducing the expansion of cardiac diseases via early detection of diseases and provision of effective treatment.

Introduction

Wound is a disruption to the epithelial integrity of the skin, extended in-depth to subcutaneous tissue and other body parts such as ligaments, muscles, blood vessels, nerves, and bone (Robson et al. 2001). An appropriate wound healing is essential for the restoration of disrupted anatomical continuity (Begum, 2000). We have observed increasing interest in research based on traditional medicines of the world in the recent era (Medina-Franco et al. 2013). Traditional and complementary medicine regains popularity not only in developing countries but also in developed countries. Common and known practices across the globe of traditional medicines include Herbal, Ayurveda, Siddha, Unani, Iranian, Islamic, Vietnamese, Chinese, Acupuncture, African and other pseudo-medical knowledge (Dorai 2012). According to World Health Organization (WHO), traditional medicine ‘the health practices, approaches, knowledge and beliefs incorporating plant, animal and mineral-based medicines, spiritual therapies, manual techniques and exercises, applied singularly or in combination to treat, diagnose and prevent illnesses or maintain well-being’. Saxena et al. (2013) reported that phytochemicals present in plants are liable for preventing disease and promoting health. Antibiotics used in the treatment of wound infections are now proved to have adverse effects in the human body and in pathogens where resistance is emerging. Attention has, therefore, turned towards extracting biologically active compounds from plant species having wound healing property (Pattanayak and Sunita, 2008).

Contagious

Bovine Pleuropneumonia (CBPP) Contagious bovine pleuropneumonia (CBPP) is an infectious disease of cattle caused by Mycoplasma sp. and characterized by cuprous pneumonia, pleurisy and dilation of lymph vessels (Fig.5.1).

Etiology

• Mycoplasma mycoides

Pathogenesis

The infection spreads through inhalation of droplets from infected animals. The recovered animals act as source of infection at least for a period of 3 years. After entering through respiratory tract the organism reaches to bronchioles. It may remain in retropharyngeal gland from where it may spread in whole body. The organism from bronchioles enter into interlobular septa and causes inflammation followed by edema which causes dilation and subsequent thrombosis of lymph and blood vessels prior to development of pneumonic lesions. Death occurs due to anoxia and toxaemia.

Introduction

The managemment of pests and diseases in agriculture is challenging for farmers. Antibiotics and chemical pesticides are commonly used in traditional methods, which can be harmful to human health, the environment, and the long-term sustainability of agricultural practices. This article explores innovative approaches to pest and disease management in agriculture that are changing the game (Lykogianni et al., 2021). Techniques for controlling diseases and pests in field crops are necessary to keep agricultural systems healthy and productive. Farmers and agricultural professionals can prevent, monitor, and control pests and diseases that can significantly affect crop yields in a variety of ways. These administrators are practicing strategies to find a balance between restricting the use of chemical inputs, promoting sustainable agriculture, and maintaining financial viability.

Principle of Integrated Pests and Disease Management (IPDM)

• Suppression and Prevention: The elimination and prevention of pests are the first tenets of IPM. IPM aims to prevent a single pest from dominating a cropping system or causing damage, not eliminate all pests (Barzman et al., 2015). Three distinct sub-principles are combined in this principle: crop rotation and management, ecology, and a multi-pest strategy in combination The papers in this Special Issue discuss each of these guiding principles. A genuine illustration of the mix of strategies and multi-pest approaches is crafted by Poggi et al. (2021), who discussed ways to control wireworms in field crops. A risk assessment based on the production context (such as crop, climate, soil characteristics, and landscape) and monitoring of adult and/or larval populations should be the first steps in any new agro-ecological strategy.

10.1. Introduction

Decision-making is a fundamental aspect of human life, influencing choices in both personal and professional settings. Every individual, whether consciously or unconsciously, engages in decision-making daily, ranging from simple tasks like selecting a meal to complex strategic planning in organizations. However, decision-making becomes increasingly challenging when multiple conflicting criteria are involved. The presence of numerous factors, each with varying degrees of importance, often creates ambiguity and uncertainty, making it difficult to arrive at the most suitable option. To address these challenges, structured decision-making methodologies have been developed to provide a systematic and logical framework for evaluating alternatives.

One such widely recognized method is the Analytical Hierarchy Process (AHP), introduced by Thomas L. Saaty in the 1970s. AHP was designed to assist decision-makers in breaking down complex problems into a structured and systematic hierarchy. This approach allows for a step-by-step evaluation of different factors, making it easier to analyze their relative importance. By structuring a problem into different levels - such as goal, criteria, sub-criteria, and alternatives - AHP provides clarity in decision-making and enhances consistency in judgments. The method is particularly beneficial when dealing with decisions that involve both tangible and intangible factors, as it allows subjective preferences to be quantified systematically (Saaty, 2008).

15.1. Introduction

Meta-analysis is a statistical technique used to combine the results of multiple studies to produce a single, more precise estimate of the effect size of a particular intervention or association. It is a powerful tool in research, particularly in f ields such as medicine, psychology, education, and social sciences, where it is often necessary to synthesize evidence from numerous studies to draw meaningful conclusions. This chapter provides a comprehensive overview of meta-analysis, including its history, methodology, advantages, limitations, and applications.

15.2. Historical Background

The concept of meta-analysis dates back to the early 20th century, but it was not until the 1970s that the term was coined by Gene V. Glass. Glass defined meta-analysis as “the statistical analysis of a large collection of analysis results from individual studies for the purpose of integrating the findings” (Glass, 1976). Since then, meta-analysis has evolved significantly, with advancements in statistical methods and software making it more accessible and robust.

15.3. The Need for Meta-Analysis

15.3.1. Accumulation of Evidence

In many fields, particularly in medicine and psychology, a large number of studies are conducted on the same or similar research questions. However, individual studies may have small sample sizes, leading to low statistical power and inconclusive results. Meta-analysis allows researchers to pool data from multiple studies, increasing the overall sample size and statistical power, thereby providing a more reliable estimate of the effect size.

Introduction

India was a self-sufficient nation in its food production before independence but after the occurrence of various famines, the government in late 1960s started focusing more on the crop production i.e.,green revolution (NAAS 2019). Use of hybrids, fertilizers and plant protection chemicals increased and major investments were made on irrigation structures which led to a massive jump in the production of crops. But with time, the negative externalities caused by green revolution were vividly noticeable. The indiscriminate use of chemicals has debilitated the environment by causing soil depletion, pollution, deforestation, climate change etc. thus affecting the health of human kind. The lofty prices of inputs led the farmers to resort to debt thus falling into debt trap and suicides. In order to address this problem an alternative to the conventional farming is required which is more sustainable and climate resilient. In the mid-1990s, natural farming viz., Zero Budget Natural Farming (ZBNF) was demonstrated by Sh. Subhash Palekar also known Subash Palekar Natural Farming (SPNF). It is an agroecology based diversified farming system which involves no financial outlay to purchase essential from outside and makes farming profitable. Mishra (2018) studied on Zero Budget Natural Farming (ZBNF) and found that crops grown under ZBNF evinced higher yield than the crops grown under non-ZBNF.

Introduction

Agriculture has historically been the primary source of income in India. It has the potential to alleviate poverty, increase income, and enhances food security for 80% of both the world’s poor and people who reside in rural areas primarily work in agriculture. One of the most effective strategies to eradicate extreme poverty, increase shared prosperity, and feed an estimated 9.7 billion people by 2050 is agricultural development. Compared to other modes, the agro - based sector’s progress is two to four times more successful in enhancing the earnings of the poorest people (www.worldbank.org).

Nearly 5 billion hectares, or 38% of the world’s land surface, is used for agriculture. Around one of this is devoted for farming, and the remaining two thirds are pastures and meadows for grazing animals. Over 10% of cropland is assigned to permanent crops like cocoa plantations, oil palm plantations, and fruit tree orchards. Yet another 21% of land is primed for irrigation, a crucial agricultural land management technique.

Introduction

India has one of the world’s largest agricultural production areas of land. The net sown area is 140.1 million hectares, the net irrigated area is 49% of this, which is 68.4 million ha as per 2014–15 land-use statistics (Agriculture Research Data Book 2019). While the proportion of Indians employed in agriculture is decreasing, agriculture, along with its allied sectors such as livestock, forestry and fisheries, remains India’s primary source of income. As per the Lok Sabha Standing Committee on Agriculture (2019–20), agriculture and allied industries employed 54.6 percent of India’s total workforce. Approximately 70% of rural households still rely primarily on agriculture for a living. Agriculture and allied sectors’ share of the country’s Gross Value Added (the value of goods and services produced in an area, industry, or sector of an economy) has fallen from 18.2 percent in 2014-15 to 16.5 percent in 2019-20. As per current trends, 60% of India’s population (more than 10% of the world’s population) will face severe food shortages by 2050.

Concept of Delinting

Cotton seed clumps because of linters getting trapped on them after ginning. Gin-run seeds have very low flowability and do not singulate, making cleaning, upgrading, and precise metering in planting operations challenging or impossible. To singulate the seed and increase flowability, a variety of techniques have been and are employed. Most of the techniques entail removing the tags and linters entirely or partially, although other coating techniques have also been attempted with mixed results, both financially and technically (Mezynski, 1966; Webber and Boykin, 1907).

Methods of Delinting

1. Mechanical Delinting

Mechanical delinting is the usual technique used to improve the flowability of cotton seed. As previously indicated, mechanical delinting basically involves resharpening with finer, closer-spaced saws to remove part of the commercially valuable linters.

Stored grain pests are one of the major constraints in obtaining quality seeds. They cause substantial yield loss in storage conditions affecting both the quality and quantity of the produce. Apart from causing direct loss to the grains, they also make them unfit for consumption through their excreta, scales and wings resulting in development of unpleasant odour (Upadhyay and Ahmad, 2011). They also act as a source of medium for growth of fungi or bacteria (Daglish et al., 2018). The method of infestation of stored gain pests is different from the insect pests infesting crops under field condition. Generally, the infestation of storage pests starts after harvesting. It has been reported that in India, there is a loss of about 14 million tons worth Rs. 7000 crores due to the infestation by different storage pests (Chaubey, 2022). The post-harvest loss in terms of quantity and quality by different storage insect-pests accounts for about 10-30 per cent (Rajasri and Kavitha, 2015; Yaseen et al., 2019).

Investment Appraisal Techniques

A financial evaluation/ appraisal of Project considers the possible compensations of completing the Project against the anticipated expenses. The assessment of the project will rely on several factors, including the Size of the project, time span of project etc. The motivation behind the financial evaluation is to decide if the project is advantageous, contrasting its expenses and its expected normal advantages. These methods are primarily designed to evaluate the effectiveness of a new project. This investment evaluation technique includes Payback Period, Internal Rate of Return (IRR), Net Present Value (NPV), Accounting Rate of return (ARR), Profitability index etc. Each of these techniques evaluates the project from various angles and provides very useful insights. Investment appraisal techniques are divided in two parts namely, discounted cash flow methods and non-discounted cash flow methods.

Non-Discounted Cash Flow Techniques

Future cash flows are not brought to their Present value through Non-Discounted Cash flow methods. Non-Discounted Cash flow methods are also categorized into the following two techniques.

Project Implementation

Project Implementation is the process of putting a project plan into action. It takes place after the planning phase; planning phase includes key objectives, timeline and budget of the project. Execution includes organizing resources and assessing performance to guarantee the project stays within its anticipated scope and budget. It also involves handling any unforeseen issues in a way that keeps a project running smoothly.

Steps for Project Implementation

1. Assess the Project Plan: Before implementing the project, it is essential to create a plan that satisfies the expectations of the management, customers, and other stakeholders. The project manager must assess the project plan and guarantee that all team members comprehend the project and its requirements. The project manager must define the roles and the time required to complete each role. This step sets the standard for cooperation at work.

2. Execute the Plan: At this stage, the real work on the project begins. The project manager regularly discusses progress with his team. It measures progress along a timeline and tracks resource usage.

3. Make required Changes: Sometimes, during the implementation of the project, the manager has to make changes at the request of the customers or in other situations. Make these changes as needed, based on the design plan for solutions. Continue to interact with the team and ask questions to determine areas where they need more support.

4. Examine Project Data: It is crucial to gather and evaluate data throughout the execution phase of the project to assess the advancement of the project in comparison to its initial plan. Now, the day manager can use many project management software and information technology to collect and analyze real time data.

Aquaculture, the cultivation of aquatic organisms such as fish, shellfish, and seaweed, has grown exponentially in recent decades due to overfishing and the increasing demand for seafood. This chapter provides a comprehensive overview of aquaculture practices, including its methods, species, and technological advancements. It also delves into the environmental impacts associated with aquaculture, both positive and negative. Key issues such as habitat destruction, water pollution, genetic diversity, and using wild fish for feed are discussed, along with mitigation strategies and sustainable practices. The chapter concludes with a discussion on policy frameworks and future directions for minimizing the environmental footprint of aquaculture while maximizing its potential to contribute to global food security.

1. Introduction

Aquaculture, or the farming of aquatic organisms, has become a significant component of the global food system. It encompasses the breeding, rearing, and harvesting of fish, shellfish, algae, and other aquatic organisms in various aquatic environments including freshwater, brackish water, and marine water. Aquaculture's rapid expansion has been driven by the decline in wild fish stocks due to overfishing, as well as the growing global population and increased per capita consumption of seafood (FAO, 2020).

Precision fisheries, a concept adapted from precision agriculture, involves the application of advanced technologies and data-driven approaches to optimize fishing operations and resource management. This chapter explores the potential of precision fisheries as the future of fishing, offering benefits such as increased efficiency, reduced environmental impact, and improved sustainability. By integrating cutting-edge technologies such as remote sensing, GIS (Geographic Information Systems), IoT (Internet of Things), and machine learning, precision fisheries aim to enhance decision-making, maximize yield, and minimize resource wastage. The chapter discusses key components of precision fisheries, including real-time monitoring, predictive modeling, and targeted harvesting, and examines their implications for the fishing industry, ecosystems, and coastal communities. Furthermore, the chapter highlights challenges and opportunities associated with the adoption of precision fisheries and provides recommendations for policymakers, researchers, and stakeholders to harness its full potential for sustainable fisheries management and food security.

The Indian farm women have extensive workloads with triple responsibility for farm, household and community. Gradually their work is becoming harder due to climate change, degradation of natural resources, natural calamities, male migration and changing agricultural technologies. Women are extensively involved in crop production, horticulture, livestock management, post harvest operation, fisheries, agroforestry and household activities. Majority of their time is devoted towards collection of fuel, fodder and water, growing vegetables in homestead and rearing backyard poultry. They also considerably contribute for household income as agriculture wage earners and through cottage industry.

Women play a significant and crucial role in agricultural development and allied fields. The nature and extent of women’s involvement in agriculture varies greatly from region to region. But regardless of these variations, women are actively involved in various agricultural activities.

As per Census 2011, out of total female main workers, 55 per cent were agricultural labourers and 24 per cent were cultivators. However, only 12.8 per cent of the operational holdings were owned by women, which reflect the gender disparity in ownership of landholdings in agriculture. Moreover, there is concentration of operational holdings (25.7 per cent) by women in the marginal and small holdings categories. Worker Population Ratio (WPR) of women (24 %) is lower as against men (54.4 %) in the country. The workforce participation rate for rural females is higher at 30.5 percent against urban women participation rate of 20.20 percent (Mo SPI, 2022-23). As per the Annual Periodic Labour Force Survey (PLFS) Report 2022-23, agriculture had the highest estimated percentage distribution of female workers, ie. 64.3 %, with 76.2 % in rural areas and 11.7 % in urban areas.

Climate change significantly impacts agriculture, altering growing conditions, crop yields, and the livelihoods of farmers. Rising temperatures and shifting precipitation patterns can lead to more frequent and intense droughts, floods, and storms, which disrupt planting and harvesting schedules and reduce crop productivity. Changes in temperature and precipitation can also exacerbate pest and disease pressures, making it harder for farmers to protect their crops. Additionally, the increased frequency of extreme weather events can damage infrastructure and soil health, further challenging agricultural systems. These effects pose serious threats to food security, necessitating the development of climate-resilient farming practices and crop varieties, as well as policies that support sustainable agricultural development and climate adaptation.

The climate change is not “gender neutral”. Women and girls experience the greatest impacts of climate change, which amplifies existing gender inequalities and poses unique threats to their livelihoods, health, and safety.

Climate change effect on women

1. Reduced Agricultural Productivity: Climate change leads to crop failures, reduced yields, and changed growing seasons, affecting women’s income and food security.

2. Increased Water Scarcity: Changes in precipitation patterns and increased evaporation lead to water scarcity, forcing women to travel farther for water, reducing their time for other activities.

3. Soil Erosion and Degradation: Flooding and erosion caused by climate change degrade soil quality, reducing fertility and affecting crop growth, further threatening women’s livelihoods.

Introduction

In the face of a burgeoning global population, the imperative for robust advancements in food production, especially within the aquaculture industry, is more pressing than ever. The expansion of this industry necessitates a nuanced consideration of environmental, economic, and social factors underpinned by a commitment to sustainable development. However, the intensification of aquaculture, particularly in coastal regions, poses long-term environmental risks due to increased organic matter in water, demanding innovative solutions.

In recent decades, recirculating systems have emerged as a step toward sustainable aquaculture, offering an effective approach to control wastewater. High operating costs have hindered widespread adoption despite their potential, particularly in developing countries. Enter the need for a game-changing, cost effective, and environmentally friendly technology that resonates with farmers on a large scale. This is where the Biofloc system, or Biofloc technology (BFT), takes center stage. A beacon of cost-effectiveness, sustainability, and environmental friendliness, the BFT reduces water exchange to almost zero and slashes artificial feeding ratios. This revolutionary system enhances water quality and generates microbial protein for aquatic species, addressing critical challenges faced by the aquaculture industry.

Introduction

India has a coastline of 8,118 km, with an exclusive economic zone (EEZ) of 2.02 million sq km and a continental shelf area of 3,72,424 km², spread across 9 maritime States and seven Union Territories, including the islands of Andaman and Nicobar, and Lakshadweep. India represents 2.5 percent of the world’s landmass and supports a population of over one billion people. India is also one of 17 mega-biodiverse countries in the world, with 7.8% of the recorded species of the world, including 45,500 recorded species of plants and 91,000 recorded species of animals. The marine ecosystem is extremely diverse, attributed to the geomorphologic and climatic variations along the coast. The coastal and marine habitat includes near shore, gulf waters, creeks, tidal flats, mud flats, coastal dunes, mangroves, marshes, wetlands, seaweed and sea grass beds, deltaic plains, estuaries, lagoons and coral reefs.

Importance of Study

The detailed studies on the coastal and marine biodiversity of the Indian mainland are lacking, and so these habitats and the biodiversity are represented poorly. It is obvious that the biodiversity is distributed widely among different associated habitats and conserving a single area would never support all the important species and ecological processes worth protecting. Furthermore, biodiversity can only be conserved by preventing habitat loss and by restoration. The importance of any single species in the functioning of an ecosystem may not be high, but protection of a mosaic of habitats will certainly preserve diversity among the species of conservation importance. Also, to achieve the Biodiversity Aichi Targets with reference to the marine environment are to preserve ecologically sensitive areas and maintain the health of the marine environment by protection, sustainable use and conservation of marine living resources.

Introduction

Aquaculture stands as the swiftest expanding sector within the food industry, with an escalating per capita consumption of fish-derived animal protein. India, as the world's third-largest fish producer, contributes significantly to this trend, boasting a fish production of 16.24 million tons, which corresponds to 8% of the global fish production. Nevertheless, several challenges persist and must be addressed, including the absence of species-specific or functional feeds, the dearth of genetically modified strains or breeds, the availability of high-quality fish species, and the rising incidence of fish diseases. Recent strides in "omics" technologies have furnished a potent toolkit and conceptual framework that enables the comprehensive dissection of the phenotypic and functional networks of genes and proteins within cells or organisms (Mohanty et al., 2019). This innovative research domain has spawned technological advancements that harness the power of "omics" to scrutinize diverse biological systems (Ning and Lo, 2010). The integration of "omics" in aquaculture research has effectively surmounted numerous challenges related to production and reproduction, thereby ensuring its relevance and economic viability. This technology empowers researchers to analyze an array of molecules on a massive scale, marking an early and groundbreaking technological leap forward in this field.

Introduction

Aquaculture, involving the cultivation of fish, crustaceans, molluscs, and aquatic plants, has become indispensable for global food security and employment. However, the intensification of aquaculture practices, characterized by high stocking densities, has led to increased stress among farmed organisms, which in turn makes them more susceptible to diseases. Disease outbreaks in aquaculture can have devastating effects, necessitating both prophylactic and therapeutic measures to maintain the health and productivity of these organisms.

Prophylactic measures, such as vaccines and immunostimulants, play a vital role in preventing disease outbreaks. For instance, vaccines targeting common bacterial pathogens like Aeromonas hydrophila are widely used in fish farming. Immunostimulants like beta-glucans are also administered to enhance the immune response of aquatic organisms. On the therapeutic front, antibiotics remain the most commonly used agents to treat infections once they occur. However, the extensive use of antibiotics has led to several significant issues. Firstly, antimicrobial resistance (AMR) has emerged as a major concern, with the excessive use of antibiotics in aquaculture contributing to the development of resistant bacterial strains. These resistant pathogens can spread to other aquatic organisms and humans, posing a serious public health risk. Secondly, the presence of antibiotic residues in seafood can lead to export rejections, as many countries enforce strict regulations on such residues. This can result in considerable economic losses for aquaculture producers. Lastly, residual antibiotics in seafood can cause allergic reactions in consumers and contribute to the emergence of antibiotic-resistant infections.

Introduction

The global food system is anticipated to supply safe and nutritious food to a population that is expected to increase from 7.5 billion now to approximately 10 billion by 2050. Not only will there be more mouths to feed, but as incomes rise in rising and developing nations, demand for meat, fish, and dairy will rise as well (Brooks et al., 2019). Demand for agricultural commodities is rising rapidly as the world's population grows. Agriculture’s deep connections to the world economy, human societies, and biodiversity make it one of the most important frontiers for conservation around the globe (world wildlife).

Today's connected world has given entrepreneurs millions of new places to start small businesses, and the Internet has a lot of information to help them. Also, the internet has made it easier for business owners to connect with their peers, learn from their mistakes, and use their good decisions as a guide for their paths.

Introduction

Farmers Producer Organisations are associations of farmers and other rural producers formed based on membership to advance the members' common interests, engage in mutually beneficial technical and economic activities, and foster and sustain relationships with other organisations active in the same economic and institutional sphere. Farmer Producer Organisations (FPO) are a way for farmers, especially those on the margins of the industry, to band together and establish a strong front against the myriad problems plaguing the agricultural sector, including a lack of capital, knowledge, and access to markets. To better organise farmers, increase their ability to pool their resources, and increase their competitive edge in the marketplace, the Indian government's Department of Agriculture and Cooperation (DAC) has determined that Farmer Producer Organisations incorporated under the Companies Act, 1956 are the best vehicle for doing so.

Background

More than 85% of India's 12.5 million agricultural households are classified as small and marginal farmers because they own less than two hectares of land. Every farmer, on average, owns 1.33 hectares of land. For farmers, investing in cutting-edge farming techniques and high-yielding inputs like seeds and fertiliser is simply not feasible in the current economic climate. They also don't make much money off their marketable surplus when they sell it off piece by piece. One strategy for farmers to reduce the cost of inputs and increase their bargaining position in the marketplace is to form Farmer Producer Organisations (FPOs).

Introduction

India is the largest banana producer in the world. They grow bananas on an area of 9 million hectares and get 36 MT per hectare. India exported 2,000,000 MT of banana worth $1 billion to other nations. The banana production system supports the labour market, alternative food system, export eco-system, and nutritional security, among other things. The development of climate-resilient banana varieties, tissue culture protocols, macro-propagation, ornamental bananas, micronutrient mixtures, site-specific nutrient management, biocontrol agents for pest and disease control, robust virus diagnostic kits, and so on are all highly recommended and encouraged to make the banana industry sustainable and profitable in the long run. Technologies and products for use after harvest are also vital. Branding, supporting entrepreneurship via incubation platforms, marketing intelligence, and handholding for technical support are necessary to sustain banana production and drive value addition. Bananas and plantains, more than any other fruit or vegetable, constitute a staple food for millions of people worldwide and contribute to a healthy diet. In addition to carbohydrates, it's a wonderful source of potassium, vitamins, and minerals. The fat-free fruit has a calorie count of 90 per 100 grams. Dessert bananas are normally eaten raw, while plantains or cooking bananas are commonly prepared in a variety of savoury ways, such as boiling, steaming, frying, or roasting. The banana industry has expanded in recent years, making a greater contribution to the economy in terms of both employment and food supply.

Aluminium is a ubiquitous metal and seen in an environment. Source of aluminium happens through dietary souce, food addivitives, packing materials, medications, environmental exposure as well as occupational exposure. Toxico kinetics is related to the interaction of aluminium with biological systems and toxicity also. Toxico dynamics of aluminium is related to the the oxidatve stress, neuro toxicity and bone toxicity. Diagnosis is based on MRI scan and measurement of serum as well as urine. Treatment is dependent on chelation therapy as well as avoidance of exposure. Finally it is concluded that aluminium toxicity leads to health risks in a significant manner along with potential adverse effects on neurological, gastro, intestinal, renal as well as skeletal systems.

Introduction

Aluminium is a ubiquitous metal observed naturally in the environment. It is widely used in various industrial and consumer products including cookware antacids, vaccines, and food additives. While aluminium is normally considered safe in low concentrations and exposure to high levels can lead to toxicity causing a range of adverse effects on human health. In this comprehensive article, authors will provide information regarding its toxicokinetics and toxicodynamics, clinical signs and symptoms, associated lesions, diagnosis and treatment strategies.

Cadmium, a roxic heavy metal, poses risk in a significant manner especially to human health and the environment. It's wide spread industrial use and presence in various products make exposure a concern particularly for both environmental and occupational settings. Understanding the source, toxico dynamics, toxico kinetics, clinical manifestations, diagnosis as well as treatment of cadmium poisoning is critical in mitigating it's adverse effects especially on human health. Cadmium gains an entry into the environment through natural processes namely volcanic activity as well as weathering of rocks. Whatever it may be, human activities along with mining, smelting, refining of metals and manufacturing of batteries, plastics as well as pigments, are major contributors to cadmium release especially into the environment. Additionally, cadmium is seen in tobacco smoke, resulting in exposure among smokers as well as passive smokers. Once released into the environment, cadmium gains entry into the human body through many routes such as inhalation, ingestion and dermal contact An inhalation of cadmium containing dust or fumes is a prominent route of exposure in an occupational settings especially in industries namely mining, smelting as well as welding. The consumption of contaminated water and food is another general route of exposure especially for the general population. After consumption, cadmium in essential manner accumulates especially in the kidneys as well as liver with a half life of approximately 10 - 30 years in the organs. It also accumulates particularly in bones, where it consists of half life of several decades.

i) Silicon Technology

Silicon technology in agriculture refers to the use of silicon-based compounds, primarily silicon dioxide (SiO2 ), in pesticide formulations and as part of integrated pest management (IPM) strategies. Silicon technology is not a pesticide itself but is used to enhance the effectiveness of pesticides and contribute to sustainable pest management. Here are some ways silicon technology is applied in pesticide use:

1. Silicon-Based Adjuvants: Silicon-based adjuvants are added to pesticide formulations to improve their efficacy. These adjuvants can enhance the spreading, wetting, and sticking properties of pesticides, ensuring better coverage of plant surfaces and improving the retention of the active ingredient. This leads to more effective pest control and reduces the need for higher pesticide concentrations.

2. Induced Resistance: Silicon has been shown to induce plant resistance against pests. When plants take up silicon from the soil and deposit it in their cell walls, it can create physical barriers that make it more difficult for pests to penetrate plant tissues. Additionally, silicon can trigger the production of defensive compounds in plants, making them less susceptible to pest damage.

3. pH Buffering: Silicon compounds can act as pH buffers in pesticide formulations, helping to maintain the stability and efficacy of the active ingredients over a broader pH range. This can be particularly useful when mixing pesticides with other chemicals or using them in different environmental conditions.
