Food is a resource of immense importance and its safety in the whole production and supply chain, is very crucial. In the last century, drastic increase in the incidence of food borne illnesses, large-scale food poisoning outbreaks and surfacing of new foodborne pathogens and hazards were widely reported. Contaminants can enter food through various pathways in the food production process, and can occur naturally or as the result of inferior or inadequate production practices. Concerns on food safety are fuelled by the industrialization of agricultural production, liberalization of trade, tourism, food consumption pattern and food preparation practices. The availability of information through the mass and social media increases the number of reported cases of inadequate food safety. International competitiveness depends more on quality and safety concerns than on prices and this creates a need for safer food production and distribution practices.

ABSTRACT
It is impossible to envision a world without energy provisions and has become inevitable and an integral part of a nation’s prosperity. It has unparallel contributions towards the socioeconomic empowerment, industrial growth, and technological advancements, as also in mitigating greenhouse gas (GHG) emissions. Judicious utilisation of energy sources without infringing upon the sustainable energy demand is the need of the hour. Taking India’s huge bovine strength into account, biogas technology has the potential to transform the standard of living of rural millions. Effectively implementing the Govt. of India’s National Biogas and Organic Manure Programme (NBOMP) could save precocious demand on electricity, fertiliser and firewood while promoting self-sustainable organic farming. In this chapter, the cost and benefit analyses of biogas technology (involving biogas plants of different capacities) are discussed along with the long-term approach at the grassroots level to promote digested slurry for organic farming. The commercialisation and carbon crediting of biodigester technology is also narrated. It is necessary to chalk out a revenue model to commercialise slurry at the grassroots level to economically empower the beneficiaries, from family-type to industrial-scale biogas plants. Small-scale biofertiliser hubs at district level may be organised to collect dry slurry from the beneficiaries and process them further to make it market-ready through entities operating at the national level developing manure for agricultural practices, as also feeding materials for animal husbandry practices.

2.1 Overview of the CDM Project Cycle

The ultimate governing body of the CDM is the Conference of the Parties/Meeting of the Parties to the Kyoto Protocol (COP/MOP). The COP/MOP is the annual meeting of the signatories to the Kyoto Protocol and is responsible for managing the CDM Executive Board and for overseeing its work. The Executive Board supervises the CDM process under the authority and guidance of the COP/MOP; it is fully accountable to the COP/MOP. The Board decides on rules for the implementation of the CDM, as well as making the final decisions about acceptance of methodologies, registration of projects and issuance of CERs. The Board is composed of 10 members and 10 alternates. The CDM Executive Board created an A/R Working Group to specifically oversee LULUCF under the CDM. The A/R Working Group provides guidance to LULUCF project developers and, using expert reviewers, makes recommendations on acceptance or rejection of LULUCF methodologies.

Introduction

Food Safety is the assurance that food is acceptable for human consumption according to its intended use. The slogan of the World Food Safety Day 2019 “If it’s not safe - it’s not food!” portray, unsafe food is a threat to mankind. Ensuring food safety to protect public health and promote economic development is of utmost importance and it remains a significant challenge in both developing and developed countries. Food borne diseases remain a real and formidable problem, causing great human sufferings and significant economic losses. According to WHO 2019-20 World Water Day report, one third of the population of developed countries may be affected by food-borne diseases each year and the problem is likely to be even more wide spread in developing countries, where food and water borne diarrhoeal diseases kill an estimated 2.2 million people each year, mostly children. While unacceptable rates of food borne illness still remain, new hazards continue to enter the food supply.

A food safety hazard refers to any agent with the potential to cause adverse health consequences for consumers. It occurs when food is exposed to hazardous agents which result in contamination of food. In other terms it can be defined as anything that could contaminate food or could otherwise violate established food safety program criteria, if left uncontrolled. The National Advisory Committee on Microbiological Criteria for Foods (NACMCF, 1997) defined a hazard as a “biological, chemical, or physical agent that is reasonably likely to cause illness or injury in the absence of its control”.

A hazard may be introduced into the food supply any time during harvesting, formulation and processing, packaging and labelling, transportation, storage, preparation and serving. Food safety hazards are generally categorized into four classes: Physical, chemical, biological and allergens. Food manufacturers can adopt Food Safety Management Systems (FSMS), which include Good Manufacturing Practices (GMP), Good Hygiene Practices (GHP), Hazard Analysis and Critical Control Point (HACCP) and other practices to strictly check the hazards and make the food safe.

Understanding the hazards that contribute to food borne illness and injury is important to determine the necessary steps to prevent or reduce it to an acceptable level or eliminate hazards altogether before food reaches the consumer.

Rainfall in India, is a phenomenon that is not just a meteorological event but the very lifeline of the subcontinent, profoundly shaping its landscapes, agriculture, and, most importantly for our study, its diverse aquatic ecosystems and the fisheries they support. India experiences a unique and dominant rainfall regime driven primarily by the monsoon, a seasonal reversal of wind patterns. The arrival, intensity, duration, and spatial distribution of this rainfall have farreaching consequences for the availability of freshwater, the health of rivers, lakes, and wetlands, and the productivity of coastal and marine environments. For aspiring fisheries professionals in India, a thorough understanding of the patterns and vagaries of Indian rainfall is indispensable.
Consider the sheer diversity of aquatic habitats across India, from the snowfed rivers of the Himalayas to the monsoonal wetlands of the Gangetic plains, the brackish backwaters of Kerala, and the vast coastline. The characteristics and productivity of each of these systems are intricately linked to the patterns of rainfall they receive. The monsoon replenishes rivers and groundwater, sustains agricultural practices that can impact water quality, influences the nutrient flow into coastal waters, and can even trigger crucial life cycle events for many aquatic species (Fig. 7.1).

Introduction

Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of design, evaluation, and production of packages. Packaging may be defined as the art and science which involves preparing the articles for transport, storage display and use. India is a land of large varieties of fruits and vegetables due to its vast soil and climatic diversity. With 38 and 71 million tons of production of fruits and vegetables, India is the second largest producer of fruits and vegetables next to Brazil and China respectively. Apart from the huge value addition and employment involved in these activities, packaging has served the Indian economy by helping preservation of the quality and lengthening the shelf life of innumerable products-ranging from milk and biscuits, to drugs and medicines, processed and semi-processed foods, fruits and vegetables, edible oils, electronic goods etc., besides domestic appliances and industrial machinery and other hardware needing transportation (FAO, 1985).

Abstract

Tea (Camellia sinensis L. O. Kuntze), a foliage crop of Sub-Himalayan Terai-Dooars has Tea mosquito bug (Helopeltis theivora)(TMB), looper caterpillars [Hyposidra talaca, Hyposidra infixaria, Biston (=Buzura) suppresseria] and Red spider mite (Oligonychus coffeae)(RSM) as major pests. In conventionally managed tea plantations, synthetic pesticides and acaricides are routinely applied. The pesticide-exposed pest populations show higher tolerance level as evident in their increased LC50 values. Augmented activities of detoxifying enzymes viz. general esterases (GE), glutathione S–transferases (GST) and cytochrome P450 mediated monooxygenases (CYP) were recorded in the pesticide-exposed pest populations. Sub–lethal exposure to monocrotophos (36% SL) enhanced the tolerance level in adult TMB by 105 fold through three generations. Increased activity of GE was evident in the pesticide-exposed populations of the tea loopers. Activities of GE and GST  in RSM were significantly higher in acaricide-exposed population. Present studies can help developing enzyme-based assay kit for determining level of pesticide-resistance. Integrated resistance management has become an integral part of modern day IPM practices. Adoption of newer chemicals, and cultural practices can minimise synthetic pesticide applications, thereby help reducing resistance development in pests.

1. Introduction

Fungi are ubiquitously present in air, water, soil and organisms, or on organism surfaces. They are a group of eukaryotic system that are of great applied and scientific interest to common man, microbiologists, agriculturists and industrialists. They are a diverse group of organisms with respect to taxonomy, size, morphological appearance, mode of nutrition and reproduction. Fungi are eukaryotic spore bearing protists that lack chlorophyll. Fungi comprise the molds and yeasts. Yeasts are usually unicellular measuring only several microns in diameter, whereas molds are filamentous and multicellular which may grow up to several meters in diameter like the extremely large polypores. Fungi generally reproduce both sexually and asexually (Gow and Gadd 1995).

Although it is not easy to define fungi, biologists currently use the term “Fungus” to include nucleated, spore bearing, achlorophyllous organisms with absorptive nutrition which generally reproduce sexually and asexually, and whose filamentous branched somatic structures are typically surrounded by cell walls containing cellulose of chitin or both. A feature which all fungi have in common is their mode of nutrition. Like animals, fungi are heterotrophic organisms, which must consume preformed organic matter. They may live as saprophyte or parasites. They are of great economic importance to man and play an important role in the disintegration of organic matter and affect us directly by destroying food, fabric, leather and other commercial goods. They are responsible for a large number of diseases of plants, animals and man.

Introduction

Fruit and vegetable development starts with formation of an edible part fruit setting, seedling emergence, tuber development and ends with loss of edible character, or spoilage through physiological deterioration, development of fibrous character or spoilage through microbiological intervention . The state of maturity of a fresh horticultural commodity is therefore is a continuum process along the development scale. The term mature implies that point in the development scale when the horticultural commodity in the state that is ready to use (consume, process, store). For the packing house, maturity means suitability for storage followed by sufficient shelf life to assure profitable supply to markets. On the other hand, the retail consumer may value colour, flavour, or textural attributes. This implies that maturity and an appropriate compromise must be achieved through the marketing process.

Quality, on the other hand, relates to the degree of the satisfaction that the consumer or customer is likely to obtain through the use of mature commodity. Maturity and quality are interrelated with market expectations or requirements. These expectations or requirements are expressed through regulations or guidelines of grower groups or through legislative authority expressed as quality standards or grades and enforced through inspection agencies associated with government departments.

In 1920, although electric vehicles were not used on the American farms about 5,000 electric industrial trucks were produced by 12 American manufacturers, while estimates of the total fleet ranged from 6,000 to 15,000, most of them built during the war. Most used an exchange charging system. Among the manufacturers seen in and around cities and towns were the Commercial Truck Company, the Lansden Company, the Walker Vehicle Company (now owned by Commonwealth Edison), the Ward Motor Vehicle Company, the Steinmetz Electric Motor Corporation, Walter Motor Truck Company, and the Baker R L Corporation.One step away from agriculture, Charles A. Ward of New York City, was head of his family’s baking company, made up of the Mackey Company, the Ward Corby Company, the Ward Bread Companyand the Ohio Baking Company of Cleveland. In 1911, Ward had decided to replace his horse-drawn delivery vehicles with electric trucks, thus doing away with the unsanitary stable hitherto part of or adjacent to bakery.¹

Alongside this, the challenge of using stationary electric agricultural machines continued to be met. Two innovations which entered into dairy farming were the milk cream electric centrifugal separator and the surge milker. The Babson brothers (Henry, Fred and Gus) of Chicago were friends of and dealers for electrical battery inventor and entrepreneur Thomas Edison, and importers of Belgian-made Méllote separators. In 1916, the Babsonsproduced their own Pine Tree milking machine. While the overall design was similar to others, the electrically powered Pine Tree Pulsator outperformed any other pulsator made. These machines were powered by a 32-volt Delco system with 12 batteries near the barn. Pine Tree Pulsators were simple enough that the farmer could maintain them himself. The Pine Tree Pulsator was patented in 1921. The problem with this unit was that it was difficult to keep clean.

Definition
Production and operations management is the process of conversion of inputs into outputs, using physical resources, so as to provide the desired utility/utilities —of form, place, possession or state or a combination thereof—to the customer while meeting the other organizational objectives of effectiveness, efficiency and adaptability. It distinguishes itself from the other functions such as personnel, marketing etc. by its primary concern for ‘conversion by using physical resources’. Figure 1.1 describes a generalized concept of production system. It takes resource inputs and processes them to produce useful outputs in the form of goods or services.

INTRODUCTION

Fig  (Ficus carica L.) is commonly known as Anjeer. It has a luscious taste as a fresh fruit. The fruit of fig have been prized over centuries for the medicinal and dietary properties. The figs are consumed fresh, dried, preserved, candied, jam and canned. 

NUTRITIVE AND CULTURAL SIGNIFICANCE

Medicinal Uses:The latex is widely applied on warts, skin ulcers and sores, and taken as a purgative and vermifuge, but with considerable risk. In Latin America, figs are much employed as folk remedies. A decoction of the fruits is gargled to relieve sore throat. Figs boiled in milk are repeatedly packed against swollen gums. Similarly, the fruits are much used as poultices on tumors and other abnormal growths. The leaf decoction is taken as a remedy for diabetes and calcifications in the kidneys and liver. Fresh and dried figs have long been appreciated for their laxative action. The food value of edible portion of fig (Morton, 1997) is given in detail in Table 1. 

Introduction

The dairy sector is one of the most important food sectors, which introduced the physical, chemical, microbiological and sensorial criteria duringprocessing steps and in the final dairy products. Several agents/ingredients of non-dairy origin are commonly used to maintain the quality of milk and milk products during processing, transportation and storage. In general, such ingredients are known as food additives and it can be antioxidants, coloring agents, flavoring compounds, preservatives(naturals and synthetic),artificialsweeteners, vitamins, minerals, stabilizers, emulsifiers and curing agents. From the safety point of view, some toxic agents can come into contact of dairy products duringmilking, storage or processing; such as fungal toxins, heavy metals, antibiotics or radionuclide’s, etc., which need to be identified and processed accordingly. Although addition of food additives in food/dairy product is controlled under country specific food laws or Codex Alimentarius Commission (CAC), few dairyproducts such as butter and unflavored fermented milk products are highly restricted for food additives.

India is bestowed with diverse agroclimatic zones which aids in the cultivation of large number of commercial flowers like rose, gladiolus, chrysanthemum, tuberose, jasmine, marigolds, orchids, lavender, lily, anthurium, gerbera, potted plants, cut foliages, bedding plants etc. In floriculture trade, value addition takes place at every step to create a novel product and to cater the demand of heterogeneous consumers. In the international floriculture trade, besides floriculture and pot plants, many other value added products include artificial colouring of the flowers to create novelty, aqua-packing for better presentation and attraction, three dimensional window packing of flowers for greater visibility, garland, venis, bouquets, flower arrangements etc.

1. Introduction

Fermented milk products such as yoghurt are produced through out world (Kurmann et al., 1992). Yoghurt can be characterized as a gel like coagulated milk product, having a smooth consistency and a pleasing flavour and is now widely consumed both by infant and adult populations. It is common that yogurt preparation involves the use of equal amounts of two lactic acid bacteria (LAB): Streptococcus thermophillus (St) and Lactobacillus delbrueckii ssp. bulgaricus (Lb); samples prepared with these starter bacteria are labeled Lb-St (Ng et al., 2011). In the early stage of the incubation process, Lb stimulates the growth of St releasing amino acids from casein (where the most important is valine) and producing a moderate reduction in pH due essentially to St. Yoghurt has better digestibility than milk and this is related to its comparatively high content of free amino acids. Besides nutritional value, it possesses hypocholesterolaemic (Mann, 1977) and antitumour effects (Odd et al., 1983; Reddy et al., 1983).Yoghurt may be set or stirred and has a potential for being used as dietary supplement for infants. So they cross the line between dietary supplements, health foods and conventional foods with great facility. Now a days, emphasis is given on sweeteners and more natural sweeteners will be used (Hollingsworth, 2001). Natural sweeteners can be easily incorporated in yoghurt by blending cattle milk with fruit pulps like mango. The enhancement of other nutrients e. g. vitamins and minerals will be added advantage. Mango pulp which contains a high proportion of sugar, mostly monosaccharide, is easily adsorbed by the digestive systems (Celik and Bakirci, 2003).

Soybean is a comparatively inexpensive source of high quality protein. The protein and fat contents in soybean are above 40 % and 20 %, respectively. Nutritionally, soy protein is a more balanced plant protein for human consumption. Studies have indicated that consumption of soy protein decreases total serum cholesterol and minimizes risks for several cancers (Anderson et al., 1995; Messina, 1997; Zind, 1998). The positive health benefits associated with soybeans have greatly increased its consumer awareness which has created a large market for soy foods (Ohr, 2000; Liu, 2000). The problem of beany flavour in soy products can be overcome by lactic acid fermentation (Buono et al., 1990; Granata and Morr, 1996). Soy solids are not only abandoned source of protein but also have therapeutic properties against breast, prostate, colon and lung cancers due to its isoflavones like genistein and daidzein content. Fortification with soy made yoghurt beneficial in lowering cholesterol level and blood pressure and in relieving symptoms of menopause and osteoporosis.

Origin and Domestication of Pigs

Pigs are nonruminant, even-toed ungulates and belong to suborder Suina which includes hippopotamuses, peccaries and pigs. All true pigs are members of the family Suidae which includes five living genera namely Sus, Babirousa (babyrusa), Hylochoerus (giant forest hog), Phacochoerus (warthog), and Potamochoerus (bushpig and red river hog) that can be called as pigs. European breeds are believed to be descendants of the European wild pig Sus scrofa and Asiatic or oriental breeds originated from the Eastern Asiatic banded pig, Sus vittatus a successor of Sus crystatus.

Introduction

There has been a slow evolution of information technologies in fruit crop production as innovators combined their prior field experience with an attitude of learning by doing while looking for practical applications for farm management. As a suite of technologies became available for use in agriculture production, a new management strategy that combined information with decision making became known as Precision farming. Precision farming is the emerging technology which involves maintaining of crop inputs on site specific basis with reducing waste, increasing the profits and maintaining the quality of environment. The main tools involved in this are Geographical Information System (GIS), Variable Rate Technology (VRT), Global Positioning System (GPS), Yield Monitoring and Remote Sensing.

The biotic component of earth is continuously and significantly affected by the abiotic components. Physical factors of the environment (temperature, humidity, rainfall, wind, solar radiation, light, atmospheric pressure, etc) surrounding the animal have influence on the production, reproduction and welfare of the animal. Livestock performance is best when environmental factors are optimum which is difficult to achieve due its variable nature. To this complex livestock-climate interaction, animal responds favorably by undergoing ‘adaptation’ or unfavorably by being under ‘stress’. Type and magnitude of stress due to physical environment depends on climatic factors of a particular area, animal adaptability, breed characteristics and managemental interventions by humans to minimize the losses. To understand the physical environment of livestock frequently used terms are mentioned below

1.1 INTRODUCTION

Geographic Information System (GIS) is the new emerging field and grows at very rapid pace. Now GIS is a billion dollar industry with applications in varied disciplines. At present, GIS is being used by professionals from various disciplines. In this decade, GIS is being used by experts who are good in GIS technology for various applications. The development trend indicates that GIS will be used by common man in near future and at the same time, advanced GIS analysis will be carried out by GIS experts.

Any technology is developed out of necessity and GIS is of no exception. When a large amount of data were available for water distribution systems, road network, sewer lines, telecom lines, electricity lines, gas pipe lines, state wise population, natural resources etc, it is important to store, maintain and retrieve the data for applications. It is not possible to manually browse through the large amount of paper records. Also even if the data is available in an unorganized way in the computerized environment, it is not useful. Hence if the data are referred to locations in earth surface and the data are stored in an organized way, it is possible to retrieve and analyse the data for applications. Hence the solution is GIS and developed today into reality. Developed countries are using GIS widely in many areas but developing countries are moving towards the development of GIS database for their resources.

Remote sensing, aerial photography, cartography, surveying and other field instruments for attribute data collection contributes to the data acquisition. Cartography, surveying, geography, geodesy contributes for mapping process. Disciplines like computer science and statistics, mathematics involved in processing and analysing data . Computer science and mathematics involved in storing the data structure.

GIS maps are intelligent. It has many advantages compared with paper map in this digital age.

Spatial data means data which are referenced to earth. Maps, satellite imageries, aerial photographs are example of spatial data. Attribute data which are attached to spatial data are called as aspatial data or non-spatial data.

If these data are brought into GIS then it is stored in a standard format, it is possible to update, share, retrieve, manipulate and analyse quickly. Much of the time and money is saved in case of reproduction and better decisions could be made

1. Wasteland

Introduction

In the vast tapestry of Earth’s landscapes, certain areas have been relegated to the sidelines, deemed unproductive and often dismissed as wastelands. However, the term “wasteland” carries a complexity that extends beyond mere barrenness; it encapsulates a narrative of neglect, degradation, and, crucially, the latent potential for transformation.

The Dynamic Nature of Wasteland

At its core, a wasteland is a geographical space characterized by low productivity, often manifesting in barren, unproductive landscapes. The term, however, fails to encapsulate the dynamic and evolving nature of these areas. Wastelands can result from a confluence of natural processes and human activities, making them heterogeneous entities requiring careful examination (fig 1).
