10.1 Public Concerns About GMOs
10.1.1 Introduction
Genetically Modified Organisms (GMOs), particularly transgenic crops, represent one of the most transformative breakthroughs in modern biotechnology. Despite their promise to address global challenges such as food insecurity, pest infestations, and climate resilience, GMOs have also triggered significant public concern. These concerns, though varying across regions and socio-political contexts, typically revolve around human health, environmental safety, ethical considerations, corporate control, and regulatory transparency. Understanding these public apprehensions is crucial for biosafety policymaking and responsible biotechnology governance.
10.1.2 Human Health-Related Concerns
A. Allergenicity and Toxicity
One of the most widely voiced apprehensions is that transgenic foods might introduce new allergens or toxic compounds into the food chain. The insertion of foreign genes, particularly from non-food species (e.g., bacteria, viruses), raises the possibility that novel proteins could elicit allergic responses or metabolic imbalances in humans.
Example: The case of a transgenic soybean incorporating a Brazil nut gene was withdrawn from commercialization after tests indicated it could cause allergic reactions in individuals sensitive to tree nuts.

Introduction

Fruits play a vital role in improving human health which are called as protective foods rich in vitamins, minerals, fats, oils, proteins and improves in economy of producers, exporters and industrialists. Fruit crops can be classified into two broad categories i.e. ever green and deciduous trees.

1. Evergreen fruit trees grow under tropical and subtropical climate and they are not dependent on chilling requirement for floral bud differentiation and flowering. Ex: Mango, Citrus, Guava, Sapota, Papaya etc.,
2. Deciduous fruit trees require dormancy during winter season and chilling units for floral initiation and have specialized modifications to protect sensitive growing tissue from unfavourable conditions. Ex: Apple, Pear, Peach, Plum, Apricot, Cherry, Grapevine, Walnut, Almonds etc.,

Abstract

Livestock sector plays an important role in rural livelihood, employment and income generation and is a preferred entrepreneurial area for women and unemployed youths. There are enormous enterprises to venture in livestock sector such dairy, poultry, sheep rearing, goatry, piggery, fisheries, hatcheries, processing, organic dairy, organic poultry, value added products, feed and fodder products, pet-vet consultancy and clinic etc. Women constitute about 69% of workforce engaged in livestock sector right from rearing of animals to production and product development activities. Market oriented milk & milk product production as well as poultry production will be key livestock activities to generate income on a steady daily basis for resource poor households. Livestock-based enterprises are pathways out of poverty for many people in developing countries like India, for whom animals are source of nourishing foods and regular incomes. With demands for milk, meat and eggs rising fast in many developing countries, the raising marketing of animals and animal products also allows many people to take advantage of the new growth opportunities in this sector. The projection of human population in India shows an increasing trend with alarming rate which in turn increases the demand for food especially of animal origin.

Q.1 A sampling procedure in which the units are selected with probability proportional to their some size measure, is known as sampling procedure with probability proportional to size (P.P.S.) Notations: Let there be a population of N units say Yi , (i = 1,2, ......... N), YN with their selection probabilities Pi (i=1, 2........... , N). Here Pi ? Pj V i ? J. = 1, 2, .............. N. Let yi , (i = 1, 2, ...................n) be the sample drawn from the population with probability of selection pi (i = 1, 2 -, n).

Extension teaching methods: Methods by using them new information can

pass freely between the extension worker and rural communities. Extension

education is mainly concerned with the dissemination of useful and practical

information relating to rural life and helping the rural people in the practical

application of such knowledge to rural situations. Extension teaching methods

can be classified on the basis of:

Some Definition

Farmer’s call: Call made by a farmer or homemaker at the working place of

the extension agent for getting information.

Adoptive/minikit trial: It is a method of determining the suitability of a new

practice in farmer’s situation.

Farm clinic: It is a facility developed for diagnosis and treatment of farm

problems and provides specialist advice to individual farmers.

Field day/ Farmer’s day: Methods of motivating the people to adopt a new

practice by showing what has actually been achieved by applying the practice

under field condition.

Genetic variations

Genetic variation is the presence of differences in gene sequences between individual organisms of a species.

Enables natural selection, one of the major forces driving the evolution of life.

When an individual’s offspring exhibit mutations in the traits of their parents, such offspring are called variants.

Introduction

The term cropping system refers to cropping patterns used on a farm and their interactions with farm resources, other farm enterprises, and available technology over a fixed period. The fruit based cropping system includes different fruit crops as major component on particular field for a fixed period through intercropping or multistory cropping. Intercropping is growing of two or more crops together on same piece of land simultaneously with definite row arrangements to utilize farm resources efficiently. Multistory/Multitier cropping refers to growing together of  crops of different heights at the same time on the same piece of land and thereby using land, water and space in an efficient and economic manner.

Solid wastes are all the wastes arising from human and animal activities, that are normally solid and that are discarded as useless or unwanted materials. It consists of the highly heterogeneous mass of discarded materials from the urban community as well as the more homogenous accumulation of agricultural, industrial and mining waste.

Antibiotics, often referred to as “magic bullets” in the battle against bacteria, stand out as one of the most remarkable medical breakthroughs of the 20th century. Their advent revolutionized the therapeutic landscape, consistently saving millions of lives from bacterial infections (WHO, 2020). Undoubtedly, antibiotics are a blessing to humanity, not merely for their medicinal applications but also for their diverse uses. They have long been employed in various contexts, including animal husbandry and production, serving as preventive measures in numerous underdeveloped and developing nations for decades (Majumder et al., 2020). A range of antimicrobial agents, including antibiotics, antifungals, antivirals, disinfectants, and food preservatives, function to either inhibit microbial growth or eradicate them altogether. Among these, antibiotics, specifically tailored to combat bacterial infections, are the most widely used class of antimicrobials. With their increasing and often improper use, microorganisms have developed antimicrobial resistance (AMR) (Murray et al., 2022).

Antimicrobial resistance is an inevitable evolutionary process observed in all microorganisms, and is driven by genetic mutations aimed at resisting the lethal pressures of selection. Bacteria, adapt to environmental selection pressures by developing resistance to antibacterial drugs, thereby diminishing the efficacy of these treatments (Murray et al., 2022). The widespread use of antibiotics, particularly in developing nations, further flares up the process, leading to significant repercussions such as increased rates of morbidity and mortality (WHO, 2020). The incidence and prevalence of antimicrobial resistant bacterial infections have reached alarming levels in the 21st century, posing a substantial threat to global public health akin to a silent pandemic. Antibiotic resistance knows no borders and can impact individuals of any age or gender, regardless of their location. In its present state, antimicrobial resistance (AMR) stands as one of the foremost threats, not only to global health but also to food security (Murray et al., 2022).

Introduction
Cardiovascular system consists of heart and blood vessels which include both arteries and veins. The formation of blood vessels occurs in two stages-vasculogenesis and angiogenesis. Blood islands are formed on the yolk sac by clusters of mesodermal cells. Vasculogenesis i.e., formation of blood vessels starts during third week of gestation in the blood islands. It starts first in the yolk sac and later in the allantois. Angiogenesis describes budding and sprouting of new vessels from the existing vessels. The adult heart is a modified blood vessel. The cardiogenic plate lies ventral to the pericardial coelom in the third week gestation. The position gets reversed with the forward growth of the head and folding of the embryo. Two endocardial tubes appear by the end of 6 to 7 somite stage which fuse to form the primitive heart in the 8 to 9 somite stage. The parts of the endocardial tube are- sinus venosus, atrium, ventricle, bulbus cordis and truncus arteriosus. The four chambered heart is formed by the formation of endocardial cushions, interatrial septum, interventricular septum and spiral septum. The interatrial septum includes the formation of septum primum and septum secundum. Oxygenated blood from the placenta enters the embryo by a large umbilical vein which enters the liver of the developing embryo. It is conveyed to the posterior vena cava through ductus venosus. The blood from the vena cava enters the right atrium which is sent to the left atrium through foramen ovale. Blood then enters the left ventricle and transmitted to all the parts through the aorta) The umbilical arteries arising from the aorta transport blood to placenta for oxygenation. After birth, lungs become functional as the placental circulation ceases. The formation of arterial system involves the modification of aortic arches, ventral aorta, dorsal aorta and its dorsal, ventral and lateral branches. Aortic arches appear sequentially and connect cranial portions of dorsal aorta with ventral aorta)The venous system is derived from the remnants of the cardinal system and vitelline veins and to a lesser extent the umbilical veins.

Introduction

Today, increasing attention is focused upon the impact farming practices, are having on the environment and there is an increasing emphasis on more sustainable methods of crop production. Systems need to be adopted that are more sensitive to environmental issues, genetic diversity, wildlife and their habitats and in some cases the social structures of rural communities. Furthermore, consumers around the world are more sophisticated and critical than in the past, demanding to know how and what has been used to produce their agriculturally derived products. These issues can be taken up as three main challenges: 1) to improve food security, rural livelihoods and income; 2) to satisfy the increasing and diversified demands for safe food and other products; and, 3) to conserve and protect natural resources. Several scientific advancements have been made in the field of agriculture to address these challenges.

ABSTRACT

Indian agriculture is an economic symbiosis of crop and cattle population. Millions of family dairy farming dominates India’s dairy industry, contributing 62 percent of total milk produced in the country. So, encouraging family dairy farming in rural areas is necessary to increase the milk production at national level and increase the socioeconomic status of landless and marginal farmer. In rural areas there is a major problem of milk marketing. In urban scarcity of quality milk, other side in villages especially faraway from city there is surplus milk and farmers are not interested to rear more dairy animals. Marketing of surplus milk is main problem because milk is a highly perishable item and farmers not having time and also due to less quantity of surplus milk (3-5 liter) they are not interested to go market. For this we can work in group and collect milk at one place from all members and one person go to market for selling of milk. Extra milk can be used to manufacture other milk products like ghee, peda, paneeretc by other member. Some members also engaged in other work like treatment of animals, collect information of different schemes from related offices. While engaging with rural communities, we recognised that village women are the primary caretakers of cattle and play a significant role in dairy farming. As a result, the Village Woman Dairy DevelopmentProgramme - an initiative focusing on empowering village women engaged in dairy farming. Benefits in dairy farming depend on cost of feeding, medicines, labour and income from sale of milk. Milk price is fixed and not in farmers control so we increase the income through reducing the cost of milk production. Approx 70% cost of milk production on feeding of animals. To reduce cost of feeding and medicine we fed balanced ration to dairy animals. Also reducing cost of production by feeding locally available unconventional feeds through total mixed ration feeding and urea mineral molasses block supplementation.

SYNOPSIS

There is an increasing awareness about quality of food among consumers all over the world. Organically produced food is considered to be nutritionally superior, but the available information is not conclusive.

The satellite data is available in raster format. Raster data consists of two – dimensional array of pixels or grids which stores the values representing features. All the pixels are of same size and shape with their particular coordinate location. A raster data format is shown below.

INTRODUCTION

Species of the Clupeiformes (Teleostei), commonly known as herrings, shads, menhadens, sardines, anchovies, and their relatives, are a major component of forage fishes in coastal ecosystems and dominate worldwide forage fish landings (Tacon and Metian, 2009a; FAO, 2020). Clupeiformes are globally distributed fishes with having nearly 419 marine, freshwater, and diadromous species (Bloom and Egan, 2018) and they are filter-feeding fishes that form large schools having a diverse group of trophic guilds and habitats (Bloom and Egan, 2018). Additional to providing ecological and economic support, clupeiforms contribute to global food security given their abundance, easy access, and exceptionally high nutrient content (FAO, 2018). In some human communities, clupeiforms comprise the major or the sole protein source (Alder et al., 2008; Mohanty et al., 2019). Historically, clupeiform presence has been associated with persistent human settlement, growth, and survival (Thornton et al., 2010; Levin et al., 2016).

Clupeiform fishes are ecologically diverse and span all aquatic habitats, including coastal and open marine environments, oceanic islands, estuaries, and freshwater rivers and lakes (Whitehead, 1985; Lavoue et al., 2013). Species can be restricted to marine, estuarine, or fresh waters, or they can be euryhaline, where a subset exhibit diadromy (Whitehead, 1985). Strictly marine clupeiforms (33.7% of all species) are distributed in every ocean, except for the Southern Ocean (Whitehead, 1985), while strictly freshwater species (17.8% of all species) are found on every continent except for Antarctica (Bloom and Egan, 2018). Major threats to clupeiforms are similar to those found for other groups of fishes (e.g., Roberts and Hawkins, 1999; Reynolds et al., 2005), with overexploitation as the leading threat for all clupeiforms in all habitats. While overexploitation may be the most prolific threat by impacting the highest number of clupeiforms, pollution may be the most detrimental, as it affects greater numbers of CR species. When compared to other economically and ecologically important fish groups globally assessed using the IUCN Red List methodology, clupeiforms have the lowest estimated percentage of threatened and NT species overall. Using the midpoint of species evaluated as elevated concern, roughly 11% are currently at high risk compared to approximately 22% of tunas and billfishes (Collette et al., 2011), 19% of sparids (Comeros Raynal et al., 2016), and 19% of groupers (Sadovy de Mitcheson et al., 2020).

12.1 Monitoring Strategies: Pre- and Post-Release
12.1.1 Introduction
Monitoring of genetically modified organisms (GMOs) or transgenic crops is a critical component of biosafety governance. It involves the systematic collection of scientific data to assess the presence, behavior, and potential impacts of transgenic organisms in controlled and natural environments. Monitoring strategies are divided into two principal stages:
1. Pre-release monitoring, which takes place during confined field trials, and
2. Post-release monitoring, conducted after commercial or environmental release.
These strategies ensure that transgenic technologies are introduced responsibly, maintaining human safety, ecosystem integrity, and regulatory compliance.
12.1.2 Objectives of Monitoring
• To evaluate the biosafety and efficacy of GMOs in different environments.
• To detect unexpected adverse effects on human health or the environment.
• To monitor gene flow, resistance development, or weediness.
• To ensure compliance with biosafety regulations, stewardship programs, and licensing agreements.
• To maintain public trust and provide transparency in GM deployment.

The uronic acid pathway is a minor and alternative pathway for glucose oxidation and for the production of uronic acid sugar. Uronic acids of sugars are formed when the terminal carbon’s (C6) hydroxyl group (CH2OH) of sugar gets oxidized to a carboxylic acid. Uronic acid names depend on the name of the parent sugars. Uronic acid of glucose is glucuronic acid, hexose uronic acids are hexuronic acids, and pentose uronic acids are named penturonic acids. The uronic acid pathway is located in the cytosol of the liver and adipose tissue.
The glucuronic acid should not be confused with gluconic acid (aldonic acid) and glucaric acid (aldaric acid or dicarboxylic acid). Gluconic acid (aldonic acid or “onic” acid) is obtained from D-glucose by oxidizing its aldehyde group at C1 to a carboxyl group. Glucaric acid (aldaric or dicarboxylic acid) is formed upon oxidation of both the terminal hydroxyl groups (C1 and C6) and the aldehyde. They have two carboxylic acid groups. This pathway yields pentoses & ascorbic acid or vitamin C (not in primates & guinea pigs) from glucose.

Substantial onion losses occur after harvest through sprouting, rotting, physiological weight reduction and quality deterioration. Proper harvest timing, careful handling and effective curing are therefore essential for maintaining marketability and extending storage life. This chapter explains maturity indices, including appropriate levels of top fall, and compares field curing with forced-air methods. It examines topping, grading, packaging, transportation, storage temperature, relative humidity, ventilation and disease management. Physiological and biochemical changes occurring during storage are also considered. An integrated post-harvest approach combining correct maturity assessment, suitable harvesting, complete curing, careful handling, controlled storage and regular quality monitoring can considerably reduce losses and improve year-round onion availability.

Introduction

The Web-enabled infrastructures, practices and strategies are creating confusions disruptions for virtually every institution and enterprise. The responses to these disruptions are progressively leading to new practices, business models, and strategies in a variety of domains posing challenges to the profession of librarianship. The acquisition, assimilation, and sharing of knowledge is one such sphere that is really experiencing a revolution.

Protected Cultivation

Protected cultivation (PC) may be defined as the “modification of the natural environment to achieve optimum plant growth” (Singh, 2005). Modifications can be made to both the aerial and root environments to increase crop yields, extend the growing season and permit plant growth during periods of the year not commonly used to grow open field crops. PC may also indicate comprehensive systems of ‘Controlled Environmental Agriculture’ in which all the aspects of natural environment are modified for maximum plant growth and economic return.
