Meteorology is defined as the branch of science concerned with the processes and phenomena of the atmosphere. It is also defined as the climate and weather of a region. The word meteorology is derived from two Greek words: Meteor and logus. Meteor means event occurring above the earth surface and logus means to study. Meteorology is science deals with the physics, chemistry and dynamics of atmosphere and also their direct and indirect effects upon the earth surface, oceans and thereby life in general.

Climatology: Climatology is scientifically defined as weather conditions averaged over a period of time. Different regions of the world have different characteristic climates which determine the crops of any region. Climatology is derived from Greek word ‘klima’ – place/zone or slope of the earth and logs is study. It discovers, describes and interprets the climate on the basis of causes and long term effects on variation in regional and global climate. Climatology is the science which studies average condition of weather or the state behavior of the atmosphere over a place or region for a long period of time.

Agrometeorology: Agrometeorology is the study of weather and use of weather and climate information to enhance crop production. Agrometeorology is defined as the branch of meteorology that deals with relationship between weather and climate on crop, livestock production and soil management.

Most of us consider weeds to be the troublesome, competitive, aggressive, undesirable, unsightly elements of the plant world. We hate weeds since desirable plants cultivated by us are deprived of food, water, sunlight and space by these plants. They can easily colonize an area and thrive even under non-ideal conditions of growth and may affect human welfare adversely. It is perhaps due to this that the saying, when weeds win all the people lose, has come into existence.

The terminology committee of the Weed Society of America gives the simple definition of weed as a plant growing where it is not desired. King (1974) in his book Weeds of the World observed that ‘‘a plant classed as a weed in one region where it has few, if any, uses may when growing in another region, possess some very valuable uses, or in few cases may actually be cultivated’’. For instance, Bermuda grass (Cynodon dactylon) is a highly troublesome weed in crop fields, but in village pastures, it is a much sought for forage grass. Quack grass (Agropyron repens) is a very good soil binding grass on erodable non-crop lands but it is a serious weed when it infests crop fields and orchards. Campbell (1923) considered weeds as ‘honest, independent competitors for food materials in the struggle for existence’. He pointed out that the term, weed has developed in the minds of people not according to specific qualities or by a definite concept in the mind of man, but by human caprice, e.g., corn is a cultivated crop, hence, desirable plant in a corn field. However, if a corn plant grows in a Soya bean field, it is considered a weed by the Soyabean farmer. Sometimes, two persons may differ about the weedy nature of a plant at the same place and time, e.g., water hyacinth (Eichhornia crassipes) is a weed for fisherman but it is a plant of aesthetic value for a city dweller.

Thus, a corollary to the above definitions of weed is that weeds are those plants, which grow out of their place, interfere with the utilization of natural resources, prolific, persistent, resistant, competitive, harmful and even poisonous in nature and can grow under adverse conditions.

Pacemaker: A region from which waves of contraction in the heartbeat cycle are propagated.

Paedogenesis: Reproduction by the juvenile form; the production of eggs or young by an immature or larval stage of an animal; reproduction by larviform individuals.

Paeudotrachea: A ridged groove on the ventral surface of the labellum of some higher Diptera, used to take up liquid food.

Page precedence: The principle that when two or more conflicting homonyms or synonyms are published in the same work (or portion of a work) and, as a consequence, are of the same date, the names shall have priority according to the sequence in which they first appear in the work (or portion) concerned.

Paint gun: Type of small, hand-carried, air-blast machine.

During the last decade organic agriculture has emerged as a dynamic alternate farming system. This has been necessitated as a consequence of resource degradation because of to achieving high yields in various crops to meet the increasing demand of food by the burgeoning population. These have resulted in change in soil structure, imbalance in soil micro-organisms and organic matter, resistance among various weeds to weedicides, increased salinity, sodicity and have affected the water holding capacity of the soil and brought in health and environmental problems. Organic farming is a specified form of diversified agriculture that not only aims to produce nutritious food of high quality but also lead to the generation of more income and employment opportunities for rural population. In true sense, organic farming is a production system which avoids or largely excludes the use of synthetic fertilizers, growth regulators, livestock feed additives and pesticides. Moreover, it relies on agronomic management practices like crop rotation, crop residues, animal manures, legumes, green manures, off-farming organic wastes and aspect of biological pest control to maintain soil productivity.

The inability of Indian agriculture to meet the demand for food in the country during the two and half decades immediately after independence had been a matter of concern at those times. The system of our agriculture based on the traditional knowledge and practices handed down from generation to generation could not produce enough to feed the increasing population. The ignominy of our dependence for food on the western developed nations and the politics of food aid practiced by them added to our determination to be self-sufficient in food production by modernizing agriculture. The green revolution fulfilled our aspirations by changing India from a food importing to a food exporting nation. However, the achievement was at the expense of ecology and environment and to the detriment of the well-being of the people.

Heat desiccated products represent khoa and khoa-based sweets, rabri, basundi, etc. These are important traditional dairy products. Traditional dairy products and a great assortment of sweets is an integral part of Indian heritage. These products are endowed with enormous value and enjoy tremendous mass appeal. Of great social, religious, cultural and economic importance these products have been developed over a long period of culinary skills and carry with them, the age-old wisdom and experience. Traditional dairy products have always played a pivotal role in preservation of precious milk nutrients and promotion of its consumption among masses. The increased availability of milk during the flush season coupled with lack of facilities to keep liquid milk fresh during transit from rural production areas to urban market has led to the conversion of milk into variety of traditional products. In addition to preservation of milk solids for longer duration, manufacture of traditional dairy products adds value to milk and also provides tremendous employment opportunity. It is estimated that about 50% of milk produced in India is converted into a variety of traditional products.

Traditional dairy products represent the most prolific segment of Indian dairy industry. These products not only have an established market in India but also have a great export potential because of strong presence of Indian diaspora in many parts of the world. In view of the growing awareness towards the safety aspects of milk-based sweets in India, the consumer shall prefer to buy these products from the organized sector. Despite the widespread popularity and acceptability of traditional milk products in the Indian market, the organized sector has so far not been able to tap into this market potential for many reasons such as lack of published literature on their technology, inadequacy of appropriate technologies for their commercial exploitation, inadequacy of appropriate packaging materials and labeling to take care of new pattern in consumer demand, low keeping quality and a lack of quality assurance systems.

6.1 Introduction

Consumer demand, regulatory guidelines and economic power of the consumer as well as ascertained profitability stimulated the need of novel food processing techniques. The concept of “fresh”, “natural”, or “organic” food also led to the development of environmentally sound and resource efficient food processing technologies. Thermal processes have been used for food preservation since a long time. These are not very energy efficient and can change the phase of food from fresh to cooked as well as it can alter the nutritional and sensory qualities. Thus, the quest for energy conservation by the manufacturers to reduce carbon footprint of the processes involved in food processing and preservation as well as to fulfill consumers’ requirement for fresh-like quality food have given rise to the development of innovative non-thermal food processing technologies i.e. ionizing radiation, high-intensity light pulses, high isobaric pressure, electric or oscillating magnetic fields, as well as pulsed electric fields (PEF).

Application of electric energy in food processing started in the early 1900s. In the beginning, electrical pasteurization inactivated microorganisms by increasing the temperature of samples by means of an electrical resistance (ohmic heating). Milk was the first electrically pasteurized product. In the late 1940s, electric fields were used to increase the permeability of fruits to facilitate the subsequent extraction of juices. The PEF technology as a non-thermal process is very effective for inactivation of microorganisms, increasing the pressing efficiency, enhancing the juice extraction, and for intensification of the food dehydration and drying process. The main effect of PEF technology is based on the phenomena that biological membranes are punctured under the influence of external electrical impulses. This process is often referred as non-thermal, since the structural damage to membranes is implemented at very low temperature compared to the conventional heating process. The PEF process is considered to be energy efficient because the electric energy is released in short pulses, thus total energy requirement is much lower than other continuous preservation technologies. The microbial inactivation can be achieved at ambient or moderately elevated temperatures by the application of short-bursts of high intensity electric fields to liquid foods flowing between two electrodes or to semi-solid/ solid food between some specialized electrode and treatment systems. Due to chemical/physical properties and presence of electrical charge, the liquid foods (e.g. milk or fruit juices) had different conductivity, which results in variable flux of electrical current through the food systems.

Mango occupies a pre-eminent place amongst the fruit crops grown in India and is acknowledged as the ‘King of Fruits’. Mango is the pride of the garden and one of the choicest fruits known to mankind. Mango possesses unique nutritional and medicinal qualities apart from being a rich source of vitamins A and C. Young and unripe fruits are utilized for culinary purposes, preparing pickles, chutneys because of their acidic taste as well as for extraction of tannin and other astringent products. Ripe fruits are a delicacy for the table and are utilized in preparing squash, juices, nectar, jam, cereal flakes, custard powder, baby food, mango leather and toffee. Canned mango slices and pulp are indeed very popular. The inside kernel of the stone being rich in carbohydrates, calcium and fat, can be used as a source of food for certain industrial purposes.

The world turned into a grossly inhabitable during the infamous COVID-19 pandemic, with community health issues everywhere. Each one felt unsafe if other earthly inhabitants were, be it humans or other living beings. Onset of SARS CoV-2 set a ‘new normal’ world order. The ever-evolving and mutating SARS CoV-2 variants extended the pandemic wave after wave thereby complicating the situation, pushing the global healthcare system to its limits and exposing its underbelly. The continually evolving variants were more aggressively transmissive and infective. As the world still reels under tremendous healthcare pressure, other infectious diseases are emerging as are identified by the World Health Organisation (WHO), creating international health emergency situations. The situation becomes alarming with the increasing zoonotic (spillover) and reverse zoonotic (spillback) factors being more proactive in the disease spread. There is a greater need to vaccinate not only humans but also animals, especially the domesticated ones and known reservoirs/carriers. Vaccines must be developed on priority and equitably distributed as the first step to counter a pandemic or potential pandemic. Vaccination is self-limiting due to increasing reported breakthrough infection cases. A strong link of the environmental health to the overall global health needs to be acknowledged, and due diligent measures taken. Hence, there is a strong need of the One Health approach as a 360° solution, and follow it up at global-scale both in letter and spirit. This chapter discusses spillover and spillback of diseases like SARS-CoV-2 and Mpox as case examples, the mitigation strategies and the need for workable One Health models, and challenges and measures to counter future outbreaks. It stresses on foolproof vaccination strategies across to catalyse individual and herd immunities for universal wellbeing.

Food waste and loss is an enormous issue worldwide. The FAO states that ‘Hunger is still one of the most urgent development challenges, yet the world is producing more than enough food’, but a vast amount of what is produced gets lost on its way from the field to the consumer. According to the FAO, about 30% of cereals, 20% of dairy products, 35% of fish and seafood, 45% of fruits and vegetables, 20% of meat, 20% of oilseed and pulses and 45% of roots and tubers are lost or wasted. Postharvest food loss is defined as measurable qualitative and quantitative food loss along the supply chain, starting at the time of harvest till its consumption or other end uses. Food losses can either be the result of a direct quantitative loss, for example, during the process of harvest or transport or arise indirectly due to losses in crop quality such as undesired sprouting or water loss. Postharvest food loss consists of many factors, which have not changed much in the last 40 years and so postharvest food loss in general has not changed much. Figure 1 illustrates the main reasons for food loss along the supply chain and is based on ‘The food pipeline’ published by Bourne in 1977. Food loss is highest during storage due to pathogens (insects, bacteria and moulds), environmental conditions (e.g. rain, humidity, heat and frost), sprouting and quality loss (rancidity, water loss and saccharification) or animals (rodents and birds). Recently published data for Switzerland have shown that about 53%-55% of the initial fresh potato production and 41%-46% of the initial processing potato production are lost mostly due to pathogen infection, saccharification, water loss of tubers and early sprouting during storage (Buchholz et al, 2018).

The seed spices are aromatic vegetable products mostly used in whole or ground form for imparting flavour, aroma and pungency to food. The seed spices possess industrial importance and are used in cosmetics, perfumery and pharmaceutical preparations.  The major seed spices , coriander, cumin, fennel and fenugreek are cultivated in larger areas in arid to semi-arid regions covering major parts of Rajasthan and Gujarat. Besides these four crops, a minor group of under exploited seed spices crops has tremendous scope for their cultivation in arid to semi-arid parts of the country. Such under exploited seed spice crops are ajowan, dill, celery, anise, caraway, black caraway, parsley and nigella.

India produces currently 8.4 lakh t. of seed spices from an area of  5.7 lakh ha. Owing to large domestic demand and stringent export regulations only 10% of total production is exported and earns a foreign exchange of Rs. 225 crores annually. The global demand of seed spices is 1,50000 t. and India  exports only 60750 t. annually. It is suggested that if wide range of seed spice crops are grown across the country, present level of production and export can be doubled. Therefore in addition to major group of seed spices, the minor seed spices, so called under exploited crops should be given emphasis and promoted amongst farmers for earning more profit through  export.

10.1 General Description

The soil, water, and biodiversity of the land make up a complex composition. Together, these three components produce goods and services that lay the groundwork for people to live sustainably and in peace with one another. Yet an estimated 3.2 billion people's security, livelihoods, and health are at stake due to land degradation. Any decrease or loss in the biological or economic productive capability of the land resource base is referred to as "land degradation." Natural processes contribute, but humans are primarily to blame for the harm. Degradation is frequently intricately connected to biodiversity loss and the effects of climate change.

Restored lands provide access to clean water, reduce erosion, preserve livelihoods and biodiversity, create forest products, and supply biomass fuel. Trees in agricultural environments can enhance soil fertility, hold onto moisture, and boost food output. Trees and forests slow climate change by storing carbon; intensive restoration efforts may lead to a reduction in the atmospheric concentration of carbon dioxide. Restoration can assist communities in adjusting to the effects of climate change by ensuring water supplies or reducing the effects of severe storms.

Plant cultivation was only a modest activity of primarily nomadic populations in the second millennium BC, and it had little impact on the vegetation. After 0 BC/AD, sedentary civilizations created enormous settlement mounds, and on the dunes, a shifting agricultural system with fields and fallows was constructed. Park savannas, an agroforestry system with protected wild fruit trees scattered throughout the fields, were used for cultivation (Höhn and Neumann 2012). Extensive farming with protracted fallow periods was conducted during the first millennium AD. The composition of the woody vegetation changed as fallow seasons shrunk and the impact of cattle herding on the vegetation increased towards the start of the second millennium AD. The substantially lower species richness of the contemporary woody forest was eventually brought about by declining precipitation and anthropogenic pressure (Höhn and Neumann 2012).

Sex determination is one of the first aspects of nematode biology to be systematically characterized with genetic analysis and the depth of this analysis has made it a major topic in developmental biology. It is both fair and interesting to ask how general the Caenorhabditis elegans model is likely to be, both for other nematodes as well as for animals in general. As nematodes employ many different reproductive strategies, often related to parasitic life histories, one might expect similarly variable sex determination mechanisms. However, comparative studies of sex determination based on the C? elgans model have revealed both rapidly evolving and surprisingly well conserved features (Haag, 2005). This mixture of old and new (or slow and fast), along with its obvious relevance to evolution, ecology, and applied fields like agricultural and medical parasitology, has made the evolution of nematode sex determination an increasingly active research area.

1. Introduction

The agricultural sector plays a pivotal role in driving economic development in India, a nation with a population of 1.39 billion, making it the world’s second most populous country according to the United Nations’ World Population Prospects 2019. With 54.6 percent of the workforce engaged in agriculture as per the 2011 Census, and contributing 18.6 percent to the Gross Value Added (GVA) in 2021-22, its significance cannot be overstated. Notably, women play a substantial role in this sector, with rural females exhibiting a higher workforce participation rate of 41.8 percent compared to 35.31 percent for urban women (MoSPI, 2017). In rural communities, agriculture and allied sector is the primary source of livelihood that includes 80 percent of all economically active women, out of which 33 percent constitute agricultural labour force and 48 percent are self-employed farmers. Rural women are engaged at all levels of the agricultural value chain; i.e., production- pre-harvest, post-harvest, processing, packaging, marketing to increase productivity in agriculture (Nilam Patel etal, 2022). As per Pingali et al. (2019), the ratio of women to men working in the agricultural sector has increased over the time and made a greater amount of contribution to GDP per capita. They are the momentous demographic group for a sustainable food system (FAO, 2011). Empowering women in agriculture through reforms aimed at ensuring equal access to resources, skill development, and opportunities is projected to increase agricultural output in developing countries by 2.5 to 4 percent (FAO, 2011).

Reduced price volatility and stability for the market are generally a result of increased yield of crop(x12) when supply is more balanced. By providing higher yields, an increase in product delivery can be had, thereby delivering a more sustainable and predictable source that helps to keep supply and demand balanced. This lowers market volatility, creates a more stable pricing environment and reduces risk for both producers (and end buyers). Elevated or variable farming expenses or cost of cultivation(x13) may contribute to market uncertainty by impacting farmers’ earnings and shaping their choices on yield. Unpredictable expenses make it challenging to project financial results, which causes pricing volatility and inconsistent supply levels. This pricing and production volatility adds to the general unpredictability of the market.
A rise in on-farm income(x14) gives farmers greater financial stability and resources, which enables them to better manage risks and schedule production for the future. An agricultural product supply that is more predictable is facilitated by this consistency. As a result, lesser income volatility corresponds to lower overall market uncertainty and steadier prices.

Summary

Plant tissue culture is the technique of growing plant cells, tissues or organs in isolated from the mother plant on artificial media. It has opened up unprecedented opportunities in many areas of basic and applied biological research. This includes techniques and methods used to research into many botanical disciplines and has several practical objectives of plant tissue culture and micropropagation for sustainable development. Indeed, the landmark publication by Gottlieb Haberlandt who is arguably referred to as the “Father of Tissue Culture”, is often cited as the origin and emergence of plant tissue culture and its subsequent applications. Success of biotechnological approaches is dependent on regeneration of intact plants following genetic modification, generally by micropropagation. Potential uses of plant tissue culture in biotechnology to further our understanding of plant physiology, how plants function, resolution and expression of use full characters form in vitro to in vivo condition. Agro bacterium-mediated genetic transformation along with other modes of transformation such as microprojectile bombardment has been accomplished mainly through plant tissue culture.
