Pulses are considered to be the most effective means of overcoming protein and micronutrient malnutrition since they are excellent sources of dietary protein (19-25%), besides being rich in important minerals and vitamins (Ali and Kumar, 2004). In Bihar, people are mostly vegetarian in dietary habits and depend largely on pulses as the source of dietary protein. But production of pulses has not kept pace with the population growth and per capita availability of pulses has thus, declined from 61 g/day in 1950-51 to less than 28.0 g/day in 2001 as against 70 g/day the standards prescribed by ICMR. Moreover, in Bihar the contribution of cereals in total protein consumption is more than 73.0% which is not a healthy trend as cereal proteins lack many essential amino acids that are present in the pulses from which only 10.6% of total protein intake come in the diet of rural population. This alarming situation, perhaps, has arisen largely due to the quest for food security rather than nutritional security, being the prime national agenda. According to an estimate, more than 70% of gross cropped area in the state is occupied by paddy and wheat whereas, only 9.0% of it is shared by the pulses.

These cyclones and anticyclones, the large-scale rotating weather systems, characterized by distinct patterns of atmospheric pressure and wind, exert a profound influence on ocean conditions that are directly relevant to fisheries. From the dramatic impacts of cyclones – with their powerful winds, heavy rainfall, and storm surges – to the more subtle but equally important effects of anticyclones on sea state and overall weather stability, understanding these systems is crucial for anyone involved in marine fisheries. For those of you aiming to work in aquaculture, fishing operations, coastal management, or marine conservation, a solid grasp of cyclones and anticyclones will equip you to anticipate and respond to significant environmental changes. This knowledge will be invaluable for ensuring the safety of fishing fleets, managing aquaculture facilities in coastal areas, and understanding the broader ecological impacts on fish habitats and populations.
In this chapter, we will explore
• The fundamental characteristics of cyclones and anticyclones: We will unravel their pressure systems, wind patterns, and overall structure.
• Their formation and life cycle: We’ll examine the atmospheric conditions that give rise to these powerful systems and how they evolve over time.
• The direct and indirect impacts on the marine environment and fisheries: This will include the effects of strong winds on sea state, the influence of rainfall and runoff on coastal salinity, and the devastating potential of storm surges on coastal ecosystems and infrastructure.1 We will also touch upon how anticyclones can lead to periods of calm weather that can also have implications for fishing activities.
Prepare to navigate the fascinating dynamics of these atmospheric giants and understand their significant role in shaping the marine world that underpins our fisheries. Let’s begin our exploration of the whirlwinds of change!

F- distribution : A probability density function that is used in analysis of variance and is a function of the ratio of two independent random variables each of which has a chi-square distribution and is divided by its number of degrees of freedom.

F₀ value : It is used to express F-value when z =10^ºC/18^ºF and the temperature is 121.1^ºC. It is the number of minutes at a specific temperature (250^ºC) required to destroy or kill a stated number of microorganisms and has specific z-value. It is also called reference value. 

Abstract

Ever growing population and associated food scarcity are the major issues of concern globally. Microorganisms are the ultimate solution for addressing this severe problem in association with recent advances made in genomics and molecular biology. Many bacterial and fungal species which are in association with plant rhizosphere soil can immensely contribute in better growth and developments, ultimately leading to better yield. Exploring these novel organisms happens to be the need of an hour. Metagenomics and next generation sequencing technologies can contribute in identifying those microbes which are otherwise impossible to cultivate traditionally.

All bread is made by baking a dough that has two basic ingredients, flour or meal and a liquid. Bakers can use a wide variety of both components. The most common type of flour used for bread and most other baked goods is made from wheat. Wheat flour has a pleasant taste and contains a large amount of an elastic protein substance called gluten. Gluten aids in baking uniformly light bread that rises (swells) properly. Other baking flours are made from barley, rye, corn, rice, oats, soybeans, and potatoes. These flours, particularly soybean flour, may equal wheat nutritionally, but none can match wheat for creating light, even-textured bread. Hard wheat flour makes lighter bread than does soft wheat flour because it is richer in gluten. Rye and whole wheat breads are made lighter by adding white flour. The liquids used in baking include water, sweet or sour milk, yogurt, wine, and beer.

Bread is either leavened or unleavened. Leavened breads contain some substance that produces bubbles of carbon-dioxide gas. These gas bubbles inflate the dough, causing it to rise and become light and porous. Most kinds of basic breads are leavened with a fungus called yeast. Biscuits, muffins, and cakes and other pastries are leavened with either baking powder or baking soda. Unleavened bread is dry and hard. Familiar kinds of unleavened breads include water crackers, the rye crisp of Sweden, and Jewish matzoth. Whether leavened or unleavened, most breads contain other ingredients in addition to flour and a liquid. An almost limitless variety of breads can be made by adding a sweetener, shortening, cheese, eggs, meat, fruit, vegetables, seeds, or nuts. A sweetener, either sugar or syrup, is used in almost all bread for its taste or as an aid to yeast growth. Bread may also have an external sweetener in the form of a decorative glaze. The high fat content of shortening and cheese increase tenderness and flakiness in bread. Perhaps the best example is the French croissant. Eggs help leaven bread dough by adding to the bread’s lightness. They can be brushed on top of the dough before baking to create a shiny crust, as in the Jewish hallah. Some breads from many nations contain fruit, a vegetable, meat, seeds, or nuts. Examples include the fruit scone of Great Britain, the spinach paratha of India, the Southern sausage bread of the United States, the Easter sesame bread of Greece, and the almond sweet bread of Finland.

Introduction

More than three billion people are at risk of poverty due to land degradation caused by humans (Kansanga, Kerr, Lupafya, Dakishoni, & Luginaah, 2021). The implementation of Soil Sustainability Management (SSM) practices remains low among smallholder farmers, despite the fact that SSM has developed as a generally accepted technique to tackling soil degradation in Agro ecosystems (Kansanga et al., 2021). When it comes to food, water, energy, climate, biodiversity, and the provision of ecosystem services, soil plays a pivotal role in addressing these global environmental sustainability concerns (McBratney, Field, & Koch, 2014). The availability of food, fiber, clean water, and a varied landscape are all dependent on healthy soil.

Background The Gulf of Mannar is one of the world’s richest marine biodiversity areas, as well as the first biosphere reserve in the region. The EEZ (Exclusive Economic Zone) of this region is around 15,000 square kilometres, with commercial fishing taking place in about 5,500 square kilometres (Arnold John M. 2017). Throughout the year, both mechanised trawlers and non-mechanized vessels fish in this area (Arnold John M 2001). Crustaceans are the most key members of the benthic organism strata and have a higher nutritional value for humans, and a large number of tiny species contribute to the complexity and sustainability of tropical ecosystems. (Hendrickx 1995). The Brachyuran crab is one of them, and it dominates many estuary regions where salinity and temperatures can vary substantially on a daily basis. (Ng et al. 2008). There are around seven hundred genera and five thousand to ten thousand species of brachyuran crabs in the globe.

Introduction
From the tiniest insects to the largest blue whales, all species in the animal kingdom have been shown to undergo the migration. Millions of animals embark on epic journeys every year in search of food, shelter, and opportunity for mating. These animals routinely travel thousands of kilometres by land, sea, or air, which both tests and improves their endurance. Among the most striking animal migrations are those of Arctic terns. The long-distance migration of these little birds from pole to pole is well-known. They are thought to move over 40,000 kilometres (25,000 miles) a year, spending the majority of their time at sea chasing an endless summer. One of the most well-known migrations is that of the monarch butterfly, which travels across several generations. Though they are widespread throughout the United States and beyond, monarch butterflies are most known for their ability to travel 4,800 kilometres (3,000 miles) from Canada to Mexico. Millions of monarch butterflies fly south each year from their northern ranges to the oyamel fir forests near the Sierra Madre mountains, where they build massive roosts to remain warm throughout the winter. The monarchs begin their annual migration northwards in the spring, taking three to five generations to reach their goal. The migration that is the most dramatic belongs to the wildebeest. They coexist with thousands of zebras and gazelles in enormous herds that number over a million. The yearly migration of wildebeest across Tanzania and Kenya in quest of new water and grazing land is well-known. One of the most magnificent displays of nature is thought to be the migration. Animals that migrate are essential to preserving ecosystem balance and sustaining life as we know it. They distribute seeds and serve as pollinators, which support the structure and functionality of ecosystems.

Participatory water management, principles of sustainable farming and crop water productivity and strategic water management practices
Participatory irrigation management
Farmers’ participation in management of water resources is one of the prime requirements to improve the irrigation efficiency and enhance food production to meet the future requirement. The objectives participatory irrigation management (PIM) are to achieve equity in water distribution, make best use of rain, surface and ground water conjunctively, develop community responsibility to collect water charges and create a sense of ownership of water resources and the irrigation system among the users so as to promote economy in water use and preservation of system, improve service deliveries through better operation and maintenance and achieve optimum utilization of available resources.
Participation of farmers in the realm or irrigation water management implies an active role of beneficiaries in all the facets of irrigation water management and its attendant linkages with the main system of management in agricultural/agronomic activities. This role is very different from the traditional passive role of farmers to look to the department for irrigation, for water supply and its distribution. The timing of farmers’ involvement is crucial. Farmers’ participation is most effective, when it takes place from initial stages of project planning, including the stage of project formulation. Such involvement forms part of ideal conditions for a partnership between farmers and government. The present theme “more crops per drop” is feasible provided the farmers are encouraged and supported to play an active role in the operation and management of the irrigation system. However, to operationalize this concept, there is a need to involve all the farmers within the command area, so that collective and collaborative action becomes possible.
Importance of Participatory Water Management
The per-capita availability of cultivable land as well as water is going to be stagnated, wherein irrigation is the only key factor leading to increased

INTRODUCTION
    
The date palm (Phoenix dactylifera L.) is considered to be oldest among the domesticated tree fruits. It considered a symbol of life in desert because it tolerate high temperature, drought and salinity more than many other fruits. Date palm fruits are eaten as raw dates (Khalal stage), Soft dates (Tamar stage) and dry dates (Chhuhara). Different processed products viz sugar, starch, vinegar, juice, toffies, wine, chutney, jam, pickels etc. are prepared from date fruits. Leaves of date palm trees are utilized for preparation of baskets, brooms, ropes, building materials, fuel and paper. The plantation is also useful for stabilization and maintenance of ecological balance in the desert regions

Introduction

India is the seventh largest having 329.73 million ha of geographical area and second most populous country having more than a billion population in the world. There is no other substitute other than to use every square inch of land and every drop of water effectively and efficiently. Though there was markedly increase in annual food grain production from 51 (195051) million tones t0 206 million tones (200001), still the death on hunger is visualized.

The demand for food is increasing with everincreasing population growth rate. So there is no option other than to increase food production. There is very little or no scope of horizontal expansion due to land limitation, the question of vertical expansion is the only way to fit with the situation. Genetically improved crop variety, hybrids, mechanized agriculture, higher rate of fertilizers and chemicals application may give one or two more green revolution, but the question lies how far it can sustain greenness?

Adoption of improved crop cultivars, cropping system, increasing cropping intensities, precision farming can hold good to get out of this situation where whole system is to be considered.

The cropping intensities in the states like Assam, Bihar, MP, Orissa, UP and West Bengal are 137.7, 137.8, 125.6, 154.6, 148.6 and 159.6 percent, respectively (FAI, 199495). This indicated that a vast majority of lands remain fallow during dry season due to lack of proper technologies, which are under rainfed conditions, neglected. Except West Bengal, more than half of the arable land remains fallow during rainless period. Increasing cropping intensities in rainfed uplands is not easily achievable but there is great potential of intensification of cropping in rainfed lowland by utilizing natural resources and conserved residual moisture. Pulses like black gram, green gram, lentil, lathyrus, chick pea and oilseeds like linseed, groundnut, rapeseed could not only increase the cropping intensities but also come forward to increase national productivity.

The world’s fisheries, encompassing both marine and freshwater environments, play a critical role in global food security, livelihoods, and economies. However, these vital resources are increasingly threatened by the far-reaching consequences of climate change. This chapter delves into the multifaceted impacts of climate change on the fisheries sector, exploring the complex interplay between rising temperatures, altered weather patterns, and ocean acidification, and how these changes affect fish populations, habitats, and the communities that depend on them.
We will examine the ways in which climate change is altering the fundamental
dynamics of aquatic ecosystems, leading to shifts in species distribution, disruptions in food webs, and increased vulnerability to extreme weather events. Special attention will be given to the differential impacts on various regions and fisheries, considering the unique challenges faced by small-scale fisheries and developing nations. Furthermore, the chapter will discuss the potential consequences for global fish production, economic stability, and food security, highlighting the urgent need for sustainable management practices and adaptive strategies to mitigate these adverse effects and ensure the longterm viability of the fisheries sector.
13.1 Climate Change Impacts on Marine Fisheries
Climate change is significantly altering marine ecosystems, leading to profound impacts on fisheries. These changes affect various aspects of fish biology and ecology, including fishery dynamics, migration patterns, and breeding seasons (Fig.13.1). Here’s a detailed breakdown:

Introduction

Food is a culture, emotion, hospitality and prestige which is closely knitted with tradition. Traditional knowledge is a community based functional knowledge system which is developed, preserved and refined by generations through continuous interaction, observation and experimentation with their surrounding environment. It includes beliefs, values, and practices gathered from the practical experience of older generation, and its whole function is survival and development of culture of people. Traditional foods, originated from ancestral kitchens are developed through ages, invented, modified, utilised and evolved to improve nutritional and social wellbeing of the people around the world. Most of them are culture specific, region specific, environment specific, community specific and season specific. These foods are socially, culturally and economically important and provide food security, enhance livelihood and improve nutritional and social wellbeing of people. Food culture arises out of the place of a people’s origin and so traditional local foods hold the potential to bind and stabilise communities and enable a cultural continuity through conserving their histories. Indian cuisine is represented as a wide spectrum of food cultures with distinctive regional differences and preferences (Achaya, 1998).

Abstract

Continental erosion and fluvial transport play an important role enhancing mobilization of organic carbon from soils and transferring this pool to the ocean through downstream rivers and streams. The Ganges-Brahmaputra river system represents one of the largest transporters of terrestrial carbon to ocean. Intensive agriculture in the Ganges basin coupled with atmospheric deposition (AD) of nitrogen may render the soil more prone to erosion loss of carbon and nutrients. The aims of this study were to quantify atmospheric deposition of nitrogen (AD-N) in the watershed and to assess the influence of land use and AD-N on carbon and nitrogen transport in Ganga River. We collected samples in summer low flow along a 1595 km long transect of the river to assess the status of DOC under variable land use and AD-N input and, at monthly intervals along a 35 km long transect to understand seasonal patterns and the influence of local control. Our study shows average deposition of reactive-N (NO₃^- + NH₄⁺) range from 19.7 kg ha^-1yr-1 in upper stretch to 38.6 kg ha-1yr-1 in the middle stretch. The AD-N in lower stretch was almost similar to the values recorded in the middle stretch of the watershed. The average concentrations of dissolved organic carbon (DOC) and dissolved inorganic nitrogen (DIN) in the river range from 0.62 to 5.3 mg L-1 and 52.0 to 385.6 µg L-1 respectively. The land-derived carbon and nitrogen emerging in surface runoff showed positive correlation with AD-N and the river DOC showed synchrony with land use, AD-N and autochthonous carbon pool. Our data indicate that DOC in Ganga River is rising and the land use together with AD-N is an important driver of rising DOC. We suggest that future climate model should consider large scale regional time series data on changing state of atmosphere-land-water coupling and associated shifts in carbon and nutrient transport of major rivers. This has relevance predicting region specific climate change drivers and preparing action plan for integrated river basin management (IRBM).

6.1. Introduction

Food packaging has a significant contribution in preserving the quality of the food throughout the processing and storage. The package containing food should maintain the quality of the product for the longest time under particular environmental conditions. The quality of various food and beverages decline with the passage of time and food become unacceptable to consume. The time in which food deteriorates and become unacceptable is termed as shelf-life. The degradation of quality with time under storage conditions depends upon intrinsic as well as extrinsic factors. The shelf-life study of a product provides important information to manufacturer and consumer regarding the quality of the food product throughout the storage time.

Sustainability

Sustainability is a complicated concept. The most often cited definition comes from the U.N. World Commission on Environment and Development (WCED): “Sustainable development is the development that fulfills the needs of the present without compromising the ability of future generations to meet their requirements.” Hence, sustainability has been defined as meeting our own needs without compromising the ability of future generations to meet their own needs.

Introduction

According to the Forest Survey of India (FSI) “all lands, more than one hectare in area, with a tree canopy density of more than 10% is defined as Forest” (FSI 2009). The status of forests and forest management systems contribute to the vulnerability of forests to climate change. Indian forests are extremely diverse and heterogeneous. Forests and Climate Change are intimately intertwined. Forests have regulated the climate, rain, groundwater, soil of the earth over millennia. Their transpiration act as a regulator of the balance of oxygen and carbon-di-oxide: the world’s forests and forest soils currently store more than one trillion tons of carbon – twice the amount found floating free in the atmosphere. The forest and soils are home of biological diversity.

4.1. What is pH?

pH is used to classify substance as acidic, neutral and alkaline, based on the prevalence of free H⁺ ions. Water molecules on autoionization dissociate to produce H⁺ and OH^- in equal number, although degree of dissociation is very small because of its stability (about one molecule in 10 million is ionized at any one time). H⁺ ions later attached to un-ionized water molecule to give rise hydronium ions, (H₃O)⁺

1. Blast
Diagnostic Symptoms
• Pathogen attacks the crop at all stages of crop growth.
• Symptoms appear on leaves, nodes, rachis, and glumes. On the leaves, the lesions appear as small bluish green flecks, which enlarge under moist weather to form the characteristic spindle shaped spots with grey centre and dark brown margin (Leaf blast).
• Spots coalesce as the disease progresses and large areas of the leaves dry up and wither. Severely infected nursery and field appear as burnt.• Black lesions appear on nodes girdling them. The affected nodes may break up and all the plant parts above the infected nodes may die (nodal blast).
• During flower emergence, the fungus attacks the peduncle and the lesion turns to brownish-black which is referred to as rotten neck / neck rot / panicle blast (neck blast).
• In early neck infection, grain filling does not occur while in late infection, partial grainfilling occurs (Fig.1).
