Agriculture is the backbone of human civilization, providing food, fiber, and livelihoods for billions of people around the world. Crop yields, which are a critical component of agricultural productivity, are influenced by a complex array of factors, including genetics, soil quality, water availability, and management practices. However, among these factors, weather and climate stand out as two of the most significant drivers of crop yields.
Weather and climate are intimately linked, with weather referring to short-term atmospheric conditions, such as temperature, precipitation, and wind, and climate describing the long-term average atmospheric conditions in a particular region. Together, they form a dynamic duo that shapes the fate of crops, influencing their growth, development, and productivity.
The impact of weather and climate on crop yields is multifaceted. Weather events, such as droughts, floods, and heat waves, can have devastating effects on crops, leading to reduced yields, lower quality produce, and even complete crop failures. Climate, on the other hand, influences the overall growing conditions, determining the suitability of a region for specific crops and the timing of planting, growth, and harvest.
Understanding the complex interplay between weather, climate, and crop yields is crucial for ensuring food security, improving agricultural productivity, and promoting sustainable farming practices. This chapter aims to explore the intricate relationships between weather, climate, and crop yields, examining the ways in which these factors interact and influence each other. By delving into the latest research and findings, this chapter will provide insights into the following key topics:
The impact of weather events, such as extreme temperatures, precipitation, and wind, on crop yields
• The influence of climate on crop growth, development, and productivity
• The role of climate change in altering weather patterns and crop yields
• Strategies for mitigating the negative impacts of weather and climate on crop yields, such as climate-smart agriculture and weather-based crop insurance

Introduction

Agriculture accounts for a large share of Gross Domestic Product (GDP), exports, and employs more than 60% of the work force in India (FAO, 2001). The failure or success of agriculture determines the economic growth of the country. As human population grows so does the demand for food and, therefore, demand for land to grow food. Ironically, the demand to convert agricultural land to commercial and residential developments is also very high due to population growth and urbanization. This is reducing the amount of land available for agricultural purpose. This scenario is being noticed in most of the developing countries like India. Against this background, agriculture will be expected to meet food, feed, and fiber demands of a world population that is anticipated to grow from approximately 6 billion in 1999 to 11 billion by 2050 (USDA, 2010). Small and fragmented land holdings do not allow farmers to have independent farm resources like draught animals, tractors, bore wells, tube wells and other sophisticated farm machineries for various cultural operations. While crop production is the primary farming enterprise in the country, livestock raising serves as an auxiliary activity to crop production. About 90% of livestock population are in the hands of the smallholders where adequate supply of high quality forage is a common problem. Integrated farming system (IFS) models developed in different parts of the country involving dairy, duckery, poultry, horticulture, apiary, pisciculture and plantation crops viz. coconut, cocoa, nutmeg, banana, pineapple etc. along with crops, have been found to increase net profit significantly as compared to cropping alone.

Water required for irrigation of cropped land is being degraded in terms of quantity and quality due to fast increasing demand for its use. Furthermore, the soil quality and crop productivity is linked to the quality of the water available for irrigation. In general, evaluation of irrigation water quality should focus on salt content, sodium concentration, the occurrence of nutrients and trace elements, alkalinity, acidity, and hardness of the water.

Healthcare artificial intelligence depends on the quality, fairness and reliability of the data used for model development. This chapter examines the characteristics of healthcare data and explains how incomplete, inconsistent or unrepresentative datasets can produce inaccurate and discriminatory clinical outcomes. It identifies sampling, demographic, measurement, historical, institutional and annotation biases and discusses strategies for mitigating them at the data, algorithm and evaluation stages. Model robustness across different populations and clinical environments is also considered. Particular attention is given to explainable AI, human oversight, continuous auditing and interdisciplinary collaboration as essential components of trustworthy, equitable and clinically dependable healthcare systems.

The alkaloids represent yet another large group of secondary plant products. Many, but not all, exhibit important pharmacological properties & some of these have been known for hundred of years. For e.g. Cinchona alkaloids, present in bark of Cinchona spp. have quinine as their main constituent, has been known since 1639 as an effective antimalarial agent.

An alkaloid contains nitrogen, frequently as a part of a heterocyclic ring, and most are as the general name implies, basic. Alkaloids are the naturally occurring basic, nitrogenous, organic, heterocyclic ring compounds mostly of plant origin with physiological and pharmacological properties. At present, the definition is much more pragmatic and includes all nitrogen containing natural products which are not otherwise classified as peptides, amines, non-protein amino acids, cyanogenic glycosides, glucosinolates, cofactors, phytohormones or primary metabolites (such as purines and pyrimidines bases). Even a number of antibiotics produced by bacteria or fungi are therefore included as alkaloids. Alkaloids evolved early in evolution and were already present (200 million years ago) when the angiosperms began to radiate. Today, more than 12,000 alkaloids are known to occur from more than 4000 species of Angiosperms. Ladenberg defined alkaloid as :

“Naturally occurring basic, complex, nitrogenous organic, heterocyclic ring compound of plant origin with physiological and pharmacological properties.”

Pulses are legumes whose grains are consumed as dal. Thus all legumes are not pulses, but all pulses are legumes. Legumes are characterized by presence of nodules in the root systems and papilionaceous form of flowers. Pigeon pea [Cajanus cajan (L.) Millisp.], green gram [Vigna radiata (L.) Wilczec.], black gram [Vigna mungo (L.) Hepper], cowpea [Vigna unguiculata (L.) Walp.], horse gram[Macroyloma uniflorum [(Lam.) Verd.] and moth bean[Vigna acontilifolia (jacq.) Marechal] are the important kharif pulse crops grown in different parts of India. The common rabi pulses are chickpea(Cicer arietinum L.), lentil (Lens culinaris Medik.), pea (Pisum sativum L.), lathyrus (Lathyrus sativus L.) and frenchbean ( Phaseolus vulgaris ). All these have C₃ photosynthetic cycle. All form root nodules in association with symbiotic bacterium Rhizobium. Increase in concentration of green house gases, particularly carbon di-oxide, has led to global warming and climate change. The extreme weather events such as drought, excess moisture, untimely rain, cyclone, excess heat and hailstorm have become common. Crops respond differently to increase in CO₂ concentration. Both abiotic and biotic stresses due to global warming are likely to reduce productivity of pulses/pulse based cropping systems through adverse effects on crop growth and development. Birthalet al. (2014) reported higher decrease in grain yield of pulses(pigeonpea and chickpea) as compared to cereals (rice and wheat) due to rise in the minimum and the maximum temperature.

Introduction 
Fuels are essential to human existence and account for 70% of the world’s energy use. The demand for fossil fuels is rising daily due to the ongoing global population boom and has now reached a crisis point. The world’s current reserves cannot keep up with the projected 40% rise in demand between 2010 and 2040 [1]. According to Energy Information Administration (EIA) statistics, the world’s fossil fuel sources will run out in fewer than 50 years [2]. In addition, burning fossil fuels and living in an industrialised environment have released large amounts of carbon dioxide (CO2), carbon monoxide (CO), sulphur dioxide (SO2), nitrogen oxides (NOx), as well as a significant number of potentially toxic compounds into the atmosphere. This has severely degraded the natural resources that are currently available, including fossil fuels. The human and natural ecology have suffered significant damages as a result of the effects of global warming in recent years [3]. As a result, cutting CO2 emissions is crucial to preventing the negative effects of global warming. Therefore, there has been a greater focus on the improvement of CO2 capture and sequestration systems to significantly lower CO2 emissions from a variety of sources, including vehicle exhaust emissions and industrial flue gas [4] . Fuel production needs to be sustainable in terms of the environment and the economy, meaning it needs to be able to reduce CO2. It is critical to find inexpensive, sustainable, and clean energy options in order to handle the current circumstances. Currently, several traditional renewable energy sources, such as solar, biofuels, hydroelectric, geothermal, or wind are being used with varying degrees of success and detriment. Biofuels are sustainable and renewable energy sources that have emerged as a superior alternative to traditional fossil fuels in energy production. Biofuels have a lot of potential because they are abundant environmentally favourable renewable resources and their production is expanding globally, even though they are still more expensive than fossil fuels [5]. Researchers are actively investigating biomasses as a means of obtaining energy from renewable sources. It is commonly known that through a process called photosynthesis, plants can transform sun energy into chemical forms. Microalgae are fast-growing microorganisms that develop 100 times quicker than terrestrial plants. Their photosynthetic efficiency is also higher (10–50 times greater than terrestrial plants) among biomasses [6]. In less than a day, they can double their biomass. Unicellular microalgae, in contrast to plants, do not divide substantial amounts of biomass into supporting structures like stems or roots, which are costly to create energetically and frequently challenging for harvesting and processing to produce biofuel. Furthermore, they have the ability to adapt to harsh aquatic environments and economically absorb helpful substances. Moreover, 1 kg of microalgae biomass is produced by microalgae cells that fix 1.8 kg of CO2 and have a 50% carbon content [7]. Microalgae can be grown on terrain that is inappropriate for food production because of their high total yield and hence small land use footprint [8]. Microalgal species including Scenedemus sp., Chlorella sp., and Botryococcus sp.; are common, easier to grow than other species and may have higher lipid contents [9].

Abstract

Water has become a scarce resource all over the World. Water resources of Earth can be classified as surface water and groundwater in which groundwater is the main source for the drinking, domestic and agriculture. The Pudukkottai district is one of the chronic drought prone areas in Tamil Nadu. But, at the same time, the district is pitted with over 5,400 tanks/water bodies widely distributed throughout in general and clustered more in Vellar delta in particular, as the interlobel depressions have provided basic depressions for the surface water to accumulate. However, these surface water bodies are heavily silted. In Pudukkottai district, there are three divergent aquifer systems, hard rock aquifer system in the western, sedimentary aquifer system constituted by the Tertiary Sandstone (Cuddalore Sandstone) in the central and Quaternary aquifer system constituted by fluvial, fluvio-marine and marine systems in the eastern parts of the district.

2.1 Introduction

Cabbage is consumed in the raw state as well as in cooked. The word cabbage has been derived from the French word Cobache, meaning head which is best described as single large terminal bud comprised of tightly overlapped numerous leaves attached to an unbranched short stem. It is known for its rich source of vitamin A and C. It is an effective curative against scurvy disease. Cabbage leaves are low in calories (24 %), fat (0.2 %) and carbohydrates (5.4 %). It is a good source of protein (1.3 %). Cabbage is an excellent source of minerals such as calcium, iron, magnesium, sodium, potassium and phosphorus. It contains good amount of ascorbic acid. Cabbage is used mainly as a vegetable and nice pickle (sauerkraut) is prepared from it. It is also used as salads. Cabbage is well known for its medicinal properties. 

Introduction 
India’s urban transition is among the most significant in the world, both in scale and complexity. With over 34% of the population residing in urban areas as of 2018 and projections indicating that nearly half the nation will be urban by 2047, the quality of urban governance will decisively shape India’s developmental trajectory (United Nations, 2018). Urban areas are expected to contribute over 70% of the GDP by 2030. However, cities face multifaceted governance challenges ranging from infrastructure deficits and environmental stress to inadequate service delivery and institutional fragmentation (NITI Aayog, 2021). In response, digital urban governance has emerged as a transformative paradigm, leveraging information and communication technologies (ICTs) to enable responsive, efficient, and inclusive urban administration. Digital technologies are increasingly embedded into urban governance structures and processes, from e-governance portals and grievance redressal apps to real-time traffic monitoring systems and digital financial tools. This shift is reflected in flagship national programmes such as Digital India, Smart Cities Mission, and the National Urban Digital Mission (NUDM), which aim to digitise public service delivery, enhance citizen engagement, and enable data-driven decision-making at scale (Ministry of Housing and Urban Affairs [MoHUA], 2021; MeitY, 2015). At the heart of this transformation is the creation of robust digital infrastructure such as Integrated Command and Control Centres (ICCCs), city data platforms, and open APIs combined with evolving institutional frameworks that promote interoperability, decentralisation, and cooperative federalism (Kapur & Joshi, 2021; NIUA, 2023). The chapter explores the evolution and current landscape of digital urban governance in India by first outlining the conceptual underpinnings of urban governance and then transitioning into the digital domain. It analyses the role of urban digital infrastructure and the institutional architecture that supports it, highlighting the coordinated efforts under NUDM to build an open, interoperable, and citizen-centric digital ecosystem across India’s 4,400+ towns and cities (MoHUA & MeitY, 2021). Complementing this are the

Abstract

Oolichan (Thaleichthys pacificus), a small anadromous smelt also known as “savior fish”, were a necessity of life for Pacific Northwest Coastal and adjacent interior indigenous peoples, as they were the first fish to return to the rivers after winter and produced not only tasty flesh but also a nutritious oil, or “grease.” A focus of the traditional oolichan culture is the Nass River of northwestern British Columbia, Canada. The valleys and mountains surrounding the Nass River are the traditional homelands of the Nisga’a people, whose technological innovations including implements, buildings, and landscape structures facilitated fishing, production, and preservation of oolichan, as well as salmon. Over thousands of years, the Nisga’a developed plant-based technologies for use in the oolichan fishery and for preparation trade of rendered oolichan “grease”. In turn, structures and implements associated with the oolichan fishery facilitated knowledge exchange across generations, since the oolichan processing areas and fishing camps were the places where elders conveyed their cultural and ecological knowledge to younger people. Structures fashioned from plants helped people to recall the stories, traditions,

Pulses are important ingredients of human diet and principal source of protein of high biological value particularly for vegetarians. These are excellent feed for animals endowed with an unique ability of biological nitrogen fixation, carbon sequestration, soil amelioration, capable to sustain under harsh climate and an integral component of sustainable crop production system. It is expected that by the year 2050 world human population will climb to 9.7 billion, India 1.6 billion and that of Odisha will be more than 5.75 crores. It will be a great challenge by agricultural scientists for assured food security of billions of hungry human mouth with nourishing food especially pulses, oilseeds and other dietary ingredients. Current production of pulses are not sufficient to meet the requirement. In Odisha it is expected to have a shortage of 1.7 lakh tones of pulses towards 2030 if the current rate of production will not increase. The fact is almost similar for nation although India contributes 24 per cent of global pulse production but imports about 2.0 million tones every year. The deficit will further mount as the per capita consumption on dal of an Indian is increasing. It necessitates to increase pulse production which is not happening keeping pace with need (Jena et al., 2015).

Although thousands of plant species exist on the earth, only those that were found to be useful for humans as food, feed, fiber, timber and other utility materials have been selected for domestication. When these plant species were affected by various biotic and abiotic causes, the necessity arose to determine the ways and means of protecting the valuable plants species and to understand the host plant defense mechanisms and pathogenic potential of the microbial pathogens causing enormous losses to the cultivators. All plant species have built-in resistance to most microbial plant pathogens existing in the environment. Susceptibility of plants to some of them is an exception, since they are endowed with genes which effectively nullify the possible adverse conditions created by the microorganism. Likewise, microbial pathogens possess genes for survival and pathogenicity to survive in the absence of susceptible plant species and to successfully establish infection in suitable plant species. The microbial pathogens have evolved highly specialized tactics to overcome the defense responses and to rapidly multiply in plants for their survival and perpetuation in a geographic location / ecosystem

The increase in population and global industrialization has led to environmental pollution, which is a significant threat to the health of the ecological system. Different measures are recommended to remediate polluted areas effectively. The applications of nanotechnology in medicine, cosmetics, sports, textiles, and pharmaceuticals have increased over the years. Another approach to remediate the adverse effects of pollutants on the environment is by utilizing nanotechnology for contaminant remediation. Biogenic nanoparticles are tiny particles produced by biological entities such as fungi, bacteria, yeast, and algae. These biogenic nanoparticles are efficient in removing pollutants like heavy metals, pharmaceutical waste, dyes, and hydrocarbon waste. 

The reclassification of the order Rickettsiales was predicated upon comprehensive genetic analyses of 16S rRNA, groESL, and surface protein genes. Consequently, organisms within this order were systematically assigned to one of two families: Anaplasmataceae and Rickettsiaceae. Within the Anaplasmataceae family, phylogenetic analyses consistently delineated four genetically distinct clades: (1) Anaplasma, (2) Ehrlichia, (3) Wolbachia, and (4) Neorickettsia. Despite the obligate intracellular nature of rickettsial organisms in both families, those classified under Rickettsiaceae proliferate freely within
the host cell cytoplasm, whereas members of the Anaplasmataceae family are confined exclusively to membrane-bound vacuoles within the cytoplasm of host cells.
The first documented cases of anaplasmosis trace back to the late 19th century in South Africa. However, it wasn’t until 1910 that the causative agent of the disease was conclusively identified morphologically as “marginal points” within red blood cells by Max Theiler, later named it Anaplasma marginale. A year later, he identified another species, A. centrale, which caused a milder form of the disease in cattle. During the 1930s, Sanborn, Stiles, and Moc demonstrated the mechanical transmission of A. marginale by horse flies and stable flies. In the late 1980s, the life cycle of A. marginale was fully elucidated in ticks belonging to the genus Dermacentor.

Clinical laboratory tests used in the evaluation of disease states
Clinical laboratory tests are essential tools used in the evaluation of various disease states. They help diagnose conditions, monitor disease progression, and assess treatment effectiveness.
Haematological Test
Hematological tests are critical in diagnosing and managing various blood disorders and conditions affecting the blood and bone marrow. These tests provide essential information about the cellular components of blood, helping healthcare providers assess a patient’s health status and guide treatment decisions. Below is a detailed overview of common hematological tests, their purposes, and significance.
Common Hematological Tests
1. Complete Blood Count (CBC) Definition: A CBC is one of the most frequently ordered blood tests that evaluates several components of blood.
Components:
• Red Blood Cells (RBC): Measures the number of red blood cells, which carry oxygen.
• Hemoglobin (Hb): Indicates the oxygen-carrying capacity of the blood.
• Hematocrit (Hct): The proportion of blood volume occupied by red blood cells.
• White Blood Cells (WBC): Assesses immune function; elevated levels can indicate infection or inflammation.
• Platelet Count: Evaluates the number of platelets responsible for blood clotting. Purpose: The CBC helps diagnose conditions such as anemia, infection, leukemia, and other hematological disorders.

A standard operating procedure (SOP) is a set of step-by-step instructions compiled by an organization to help workers carry out routine operations. SOPs aim to achieve efficiency, quality output and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations. The military (e.g. in the U.S. and UK) sometimes uses the term standing (rather than standard) operating procedure because a military SOP refers to a unit’s unique procedures, which are not necessarily standard to another unit. The word “standard” can imply that only one (standard) procedure is to be used across all units. The term can also be used facetiously to refer to practices that are unconstructive, yet the norm. In the Philippines, for instance, “SOP” is the term for pervasive corruption within the government and its institutions.

One ofthe biggest issues the world is facing today is the lack of clean and pure water. Due to rising water demands, rigid health regulations, and xenobiotic pollutants, traditional wastewater treatment technologies cannot provide safe water. The present era necessitates innovative approaches to wastewater treatment technologies and improved water resource conservation and management materials. By utilizing innovative nanomaterial, nanotechnology guarantees a continuous provision of potable water and contributes to the preservation of water sources. Nanomaterials expedite rapid processes for the purification, conservation, and reuse of wastewater, complementing other enduring industrial methods. 

In India, we have mostly two types of standards, which govern the sale of foods including milk and milk products.

These are: Legal standards and Quality standards.

Legal standards

Legal standard means the specifications or the requirements which pertain to the law of the Govt. and are set up by the Govt. to meet certain minimum requirements in terms of chemical quality (i.e. composition), bacteriological quality (i.e. hygienic quality), and labelling and packaging requirements.

In our country, legal standards are given under Prevention of Food Adulteration (PFA) Rules, 1954-1955 (which are amended from time to time). Legal standards or PFA standards prescribe the minimum requirements for all types and categories of food. These standards are consistent with the minimum quality that is attainable under Indian conditions by the majority of the farmers, producers, processors, sale agencies etc. Further, any food that does not confirm to the minimum standards laid down by the legal rulers (PFA rules) is said to be adulterated, irrespective whether anything has been added to or removed from the original food.
