Intensive farming operations are particularly vulnerable to an increased risk of biohazards due to their densely populated livestock and close confinement. This increased animal density creates an environment where diseases can spread rapidly if not adequately managed. To mitigate these risks and safeguard the health and productivity of dairy herds, stringent farm biosecurity measures are essential. Farm biosecurity, a comprehensive framework of preventive measures and protocols, has emerged as a pivotal strategy in ensuring animal health and curbing the rise of antimicrobial resistance (AMR). By prioritizing biosecurity, dairy farmers can maintain a healthy and disease-free environment for their animals, ultimately ensuring the quality and safety of dairy products while promoting sustainable and responsible farming practices. In recent years, the interconnected challenges of animal health and AMR have prompted a re-evaluation of agricultural practices and disease management strategies.

What is Farm Biosecurity?

Farm biosecurity refers to the set of practices and measures employed to prevent the introduction and spread of infectious diseases within animal production systems. It encompasses a wide array of strategies, ranging from physical barriers and hygiene protocols to monitoring and surveillance programs. The core principle of farm biosecurity is to mitigate the risk of disease incursions by minimizing the exposure of animals to pathogens, thereby preventing outbreaks and reducing the need for antimicrobial interventions. This strategic approach can be broadly categorized into ‘external farm biosecurity’ and ‘internal farm biosecurity’, each addressing distinct aspects of disease prevention within the farm environment.

Plant diseases are classified on the basis of type of pathogenic or nonpathogenic causes of the disease. The classification is based on the plant pathogenic organisms as follows.
1. Parasites
They include both biotic and mesobiotic agents. The diseases are incited by parasites under a set of suitable environment. Association of definite pathogen is essential with each disease.
i. Biotic agents: They are also called as animate causes. They are living organisms.Biotic agents include
1. Prokaryotes
a. True bacteria or bacteria (Facultative parasites) e.g. Citrus canker.
b. Rickettsia-like bacteria (RLB) e.g. Citrus greening, Pierce’s disease of grape.
c. Mollicutes or wall-less prokaryotes
i. Mycoplasma-like organism (MLO) e.g. Sesame phyllody, Egg plant little leaf.
ii. Spiroplasma e.g. Corn stunt, Citrus stubborn.

Immunity is defined as the resistance to infection. This is carried out by the process of identification and removal of non-self material. In contrast to this, our body has to maintain immune tolerance to our own cells and tissues and develop the ability to distinguish these self-antigensfrom non-self (foreign) antigens. Tolerance means unresponsiveness of the immune system to an antigen. Immune tolerance is the process by which the immune system does not destroy an antigen. Tolerance can be either natural or induced.

Carambola (Averrhoa carambola) is a fruit of warm tropical and sub- tropical areas of the world. The fruit is oblong with three to six longitudinal ribs, resulting in a star shaped cross section when cut. Usually they have five ribs which give rise to common name of ‘five corners’ or ‘star fruit’. The tree is medium-sized, attractive and evergreen growing to about 10m. The fruit has emerged as an interesting addition to the table fruit, not only as fresh fruit, but also for its juice, decorative uses and sherbet qualities.

History

Video conferencing uses telecommunications of audio and video to bring people at different sites together for a meeting. This can be as simple as a conversation between two people in private offices (point-to-point) or involve several sites (multi-point) with more than one person in large rooms at different sites. Besides the audio and visual transmission of people, video conferencing can be used to share documents, computer-displayed information, and whiteboards.

Simple analog videoconferences could be established as early as the invention of the television. Such videoconferencing systems consisted of two closed-circuit television systems connected via cable. During the first manned space flights, NASA used two radiofrequency (UHF or VHF) links, one in each direction. TV channels routinely use this kind of videoconferencing when reporting from distant locations, for instance. Then mobile links to satellites using special trucks became rather common.

This technique was very expensive, though, and could not be used for more mundane applications, such as telemedicine, distance education, business meetings, and so on, particularly in long-distance applications. Attempts at using normal telephony networks to transmit slow-scan video, such as the first systems developed by AT&T, failed mostly due to the poor picture quality and the lack of efficient video compression techniques. The greater 1 MHz bandwidth and 6 Mbit/s bit rate of Picture phone in the 1970s also did not cause the service to prosper

In agroforestry systems the various components like tree, crop and pasture exist in different proportions and orientations. It is difficult to find out which agroforestry system is the best suited for a given land situation. Similarly, it is to be decided which technologies are required for refinement and improvement of the existing agroforestry practices. But without sufficient knowledge of the existing system in a particular land situation, it is very difficult to set the research priorities for modification and development of this system.

Diagnosis and Design (D & D) is a systematic and objective methodology developed by International Centre for Research in Agroforestry (ICRAF) to initiate, monitor and evaluate agroforestry programmes. D & D is based on the philosophy that knowledge of the existing situation (diagnosis) is essential to plan and evaluate (design) meaningful and effective programmes in agroforestry research for development. The methodology plays a strategic role in all the phases of the agroforestry research process. D & D in agroforestry is unique and it has been specially developed for the following purposes.

Abstract

The article briefly narrates the initiatives taken by the Department of Science and Technology, Govt. of India, New Delhi in providing solutions to rapidly growing Landslide Disasters in India. Duly considering the importance of the issue, the DST has embarked on a National Landslide Programme more than two decades ago and brought voluminous information on Landslide Vulnerability Mapping, Site Specific Landslide Investigations, Landslide Kinematics, Instrument Based Forewarning etc. by funding large number of research projects to various Academic/Research institutions in the country. In addition, the bilateral collaborative programme launched on Geohazards between India & Norway, resulted in bilateral flow of knowledge and capacity building amongst various tiers of the Academic, Research and the Planning Hierarchy, yielding tangible benefits.

INTRODUCTION

Landslides cause extensive damages to roads, bridges, human dwellings, agricultural lands, forests and other establishments year after year resulting in immense losses of life and properties. The entire Himalayan region has been the target of intense development activities for the last few decades. Hence the instabilities along the natural slopes are accentuated by the human activities since the development schemes are often not properly planned and implemented (Valdiya 1980; Thakur 2001). This has become the case in most of the mountains in India. Keeping in view of the stability of the slopes, the need of the hour is to achieve sustainable development of the hilly regions while implementing various developmental schemes. So there has to be a major S&T role to play to minimize the landslide problems. This should include all possible corrective and preventive measures to minimize the losses due to this disaster.

Flowers are classified into three groups- self pollinated, often cross pollinated and cross pollinated- based on the extent of cross pollination which ranges from nil to 5 percent in self pollinated, 5-12 percent in often cross-pollinated and more than 12 percent in cross pollinated flowers. The information on extent of cross pollination is important to decide appropriate breeding methods to develop and improve the crop, to maintain genetic purity of seed, and to decide safe isolation distances from varieties, related species and related genera of the crop.

3.1 Autogamous (Self pollinated) flowers

When the egg in a flower gets fertilized by its own pollen, it is, referred to as autogamy. In statistical terms, it is, explained as the probability that egg gets fertilized by its own pollen as one. The coefficient of inbreeding which also measures the probability of selfing is also one in such crops. The genetic structure of autogamous flower is homozygous. The reasons for autogamy in flowers are essentially homomorphism, cleistogamy and chasmogamy. Homomorphism refers to uniformity in placement of essential floral parts, androecium and gynoecium e.g. Aster (double flowered), Balsam, Bells of Ireland, Carnation, Clianthus, Benghal dayflower (Commelina benghalensis), Gypsophila, Lupine, Salvia, Saponaria, Sweet pea and Sweet William. In autogamous ornamental crops, cross pollination in nature is almost negligible. Autogamous pollination may be of three types viz., autogamous selfing: refers to origin of pollen from anthers of the same flower; geitonogamous selfing refers to pollen from different flower on the same shoot or genet, and xenogamy, crossing refers to pollen from different flower on a shoot from another genet.

Taxonomy (biological systematics) is the branch of science which deals with classification of units or individuals on the basis of similarities and differences. The classification, nomenclature, and identification are three interrelated components of bacterial taxonomy (Cowan, 1965).

Classification: Classification is the arrangement of bacteria into groups (taxa) based on the similarities of certain characteristics. Presently 11,000 bacterial species is classified. At the current rate of 600 bacterial species / year it is estimated to take 1000 years to classify all the bacteria!

Nomenclature: It is the assignment of specific names to the taxonomic groups following the regulations mentioned in ‘International Code of Nomenclature of Bacteria’ (Euzeby, 1997). International committee on systematic bacteriology (International committee on systematics of prokaryotes, ICSP) standardizes the code. The committee is helped by a number of taxonomic subcommittees on different groups of bacteria. The Code can be amended by the Judicial Commission. The Code contains general considerations, principles, rules and recommendations on the naming of prokaryotes (bacteria) up to the rank of ‘Class’.

Introduction

Nutrients are essential substances present in different types of foods which perform various life-sustaining functions in the body. They are required for growth, maintenance and the reproductive process. Poultry require more than 40 such nutrients, which are classified into six major groups - water, carbohydrates, protein (amino acids), fats, minerals and vitamins. Poultry diets must be formulated to provide all these essential nutrients as per the bird’s requirement to achieve optimum growth and production. Several ingredients including cereal grains, cereal by-products, fats, plant protein sources, animal by-products, vitamin and mineral supplements, crystalline amino acids and feed additives are commonly used to prepare poultry diets. Further, specialist areas such as immuno-nutrition are rapidly gaining attention due to continued advancement in the field of poultry nutrition (Beski et al., 2015).

Abstract
Agricultural marketing in India enables the producers and the consumers to have a direct contact to buy and sell their products. But it is crucial to have a clear understanding on the consumer’s perceptions and preferences for the products who are the ultimate users as a better marketing strategy. The present marketing methods are much different from traditional ones, and can be even transformed by the use of data analytics, cutting-edge technologies, and data-driven insights by the Agri-marketers to perceive and interact with consumers. The success of a firm/business is greatly influenced by consumer perception and it is shaped by a number of elements, such as marketing initiatives, customer service, and product quality. Therefore, to have a positive perception of the consumers on the products, one should focus on
the ideology and the working of their perceptions which helps to design and brand their products accordingly. The Indian agricultural marketing system is facing a wide range of issues, that prevents it from going global due to its in competitiveness in the export activities. Its high time to focus on innovative policies and strategies that support for the economic growth and the enhanced livelihoods of the various stakeholders in this system.

18.1 Introduction
Ice cream is produced by freezing a pasteurised mixture that is derived from milk or milk products, with or without nutritive sweeteners and other approved non-dairy constituents, in accordance with FSSAI standards. Except for softserve ice cream, which may remain malleable, this product must freeze solid and may contain air. Ice cream is manufactured using bovine or buffalo milk, cream, or milk products. It may also contain cane sugar, eggs, fruits, fruit juices, preserved fruits, nuts, chocolate, edible flavours, and approved colours. Up to 0.5% by weight of stabilisers and emulsifiers are permissible. The mélange must be heated to the appropriate temperature prior to freezing. A minimum of 10% milk fat, 3.5% protein, and 36% total solids must be present in the product. However, the proportion of milk fat may be reduced to no less than 8% by weight when any of the aforementioned preparations contains fruits, almonds, or both. A declaration to that effect must be included on the label, and starch may be added to a maximum extent of 5%.
18.2 Classification
Some of the frozen desserts can be classified as follows.
1. Plain: Plain ice cream has minimal coloring and flavoring, such as vanilla and coffee.
2. Chocolate: Chocolate ice cream is flavored with cocoa or chocolate
3. Fruit: Fruit ice cream contains fruits like strawberry, apricot, pineapple, mango, or banana, which may be fresh, frozen, canned, or preserved.
4. Nut: Nut ice cream includes nuts like almonds, pistachios, walnuts, or cashews, with optional additional flavoring or coloring.

Transplantation refers to the implantation of a tissue or organ from one site  to another site in an individual or from one individual to another.It involves implanting of organs or grafting of tissues to repair defects and to stimulate regeneration. Auto-transplantation or autoplasty of the skin, cartilage, bone, muscle, tendon, nerve and fatty tissue is used in plastic and cosmetic surgery. The replacement of a diseased organ by a transplant of a healthy tissue is called transplantation.

Introduction

Numerous characteristics of food determine its acceptability to consumers and to regulatory officials. Before accepting a food for consumption, it must be attractively presented, must have desirable odour and flavour characteristics and other qualities and must be free from potential pathogens or their toxic products. The ultimate nutritive qualities, flavour and appearance have been preserved and no harmful organisms or substances are present to affect the consumer adversely. If the quality of the product is good, its keeping quality is also likely to be substantial. Conversely, there are more chances of spoilage of an inferior quality food product during storage.

The aim of this book is to further strengthen the knowledge of readers on management of disasters so that they are better prepared to cope with more frequently occurring natural and manmade disasters.

The process that helps us to face disasters effectively is commonly known as disaster preparedness.  When a disaster strikes, it affects us directly and immediately. While as the government, international agencies such as United Nations, Red Cross Society, non government organizations, like Ramakrishna Mission, OXFAM, CARE, resident welfare associations in urban areas and panchayats in rural areas assist us when faced with disasters the community, invariably remains the first responders. Hence, the individuals as a part of community should prepare adequately to prevent, face and respond to disasters effectively. History has  shown that where communities have prepared adequately to confront disasters, losses to life and property have been less and environment could be protected. People living in an area may be prone to more than one type of disaster. For example Kutch District of Gujarat is vulnerable to floods, drought, cyclones and to earthquakes. Such an area is called ‘multiple hazard’ zone.

India shares 17.4% of the world population, while its land is only 2.4% of the total geographical area of the world. Naturally, the pressure on the land is often beyond its carrying capacity. Therefore, the productive lands, especially the farmlands in India are in the constant process of various degrees of degradation and are fast turning into wastelands. At present, approximately 63.85 million hectare area of the land is lying as wastelands in India (NRSA, 2005). Out of these lands, about 50% lands are such non-forest lands, which can be made fertile again if treated properly. In the last 50 years India’s lush green village forests and woodlots have been deforested to the maximum. To restore this ecological imbalance by developing the degraded non-forest wastelands, Government of India had created the Department of Wasteland Development during July, 1992 under the Ministry of Rural Development, which has been subsequently reorganized and renamed Department of Land Resources, with a broader mandate.

National Wasteland Development Board was established in 1985 mainly to tackle the problem of degradation of lands, restoration of ecology and to meet the growing demands of fuelwood and fodder at the national level. The Board was reconstituted in August, 1992 and was made responsible for development of wastelands mainly in non- forest areas in totality by involving local people at every stage of development. It aims at creating a scenario where the Government acts as a facilitator and the people at the grass root level become the real executioner of the programme. The degradation of environment in the fragile Indian subtropical ecosystem is basically attributed to the following factors.

Introduction

Gladiolus is an important commercial flower crop and is very popular as cut flower both in domestic and international market. It is a bulbous plant. Gladiolus was introduced into cultivation towards the end of the sixteenth century. The flowers are used in flower arrangement, in bouquets and for indoor decorations. In India gladiolus is commercially grown in West Bengal, Maharashtra, Uttar Pradesh, Uttarakhand, Punjab, Haryana, Sikkim, Jammu and Kashmir, Karnataka, Gujarat, Himachal Pradesh, Tamil Nadu, Madhya Pradesh, Delhi and Rajasthan.

Genetics

Gladiolus commonly called Sword Lily belongs to family Iridaceae and subfamily Ixioideae. There are about 260 species of gladiolus. It has the basic chromosome number n=15. Most members of genus are heteroploids having very small chromosomes ranging from 2n=30 to 120 (Diploid, triploid, tetraploid, pentaploid, hexaploid, octaploid and hyperaneauploid).

Introduction

Fish symbolizes as prosperity and fertility of the region rather than for its food and nutritional security in many parts of the world. The abundant inland waters resources such as reservoirs, rivers and wetlands contribute to meet the food and nutritional security of a nation. The rich diversity of freshwater fish fauna supplements as a quality animal source protein, macro and micro nutrients for the health benefits of all age group of human population. Hence, the fishery activities such as fish catch and production enhancement from inland water resources are emphasized to scale up to meet the growing demand. The world fish production through inland capture fisheries has increased from 10.5 million tons in 2009 to 11.9 tons in 2014. The utilization of the existing vast inland resources through technical interventions would impact on food and nutritional security and livelihood of the fishers and rural masses of the developing countries.
