Formulation Technology

An essential first step in any pesticide-based pest management procedure is choosing the right formulation. It’s a crucial managerial choice that affects the bottom line, client happiness, worker safety, and environmental quality. Knowing the characteristics of different formulations is important for both the supervisor and the applicator. The applicator is responsible for both application and mixing. Applicators come into direct touch with the substance, both diluted and concentrated. A basic, personal concern for one’s health and the health of others necessitates understanding the formulation’s safety features.

37.1 Introduction

Temperature describes the kinetic energy of the gases that make up air. As gas molecules move more quickly, air temperature increases. Among several environmental changes, increased air temperature affects the water cycle by increasing water temperature, which causes changes in local weather, water quality and river bodies (Gossiaux et al., 2019). This is because the water temperature is one of the most important factors for physicochemical properties of water quality (Szumiriska et al., 2020), aquatic habitats (Duggals et al., 2018), spawning rates (Besson et al., 2016) and fish growth (Collas et al., 2019) (Fig. 37.1).

Crops and trees can be protected from disease by applying pesticides at precisely scheduled intervals. It may only take a few grammes of the chemical to facilitate its distribution over the aerial parts of the plant, or to treat seeds or other propagating organs (tubers, bulbs, corns, etc.) or the soil in which plants will grow. Any chemical can be used in one of four different physical states: gas, solid, liquid, or solution. As a result, it is critical to employ the most efficient equipment to ensure a uniform deposit of the chemical on the target substrate with minimal material waste in the shortest amount of time and with the least amount of manpower.

India, hitherto reliant on foreign help, is now one of the world’s top producers of food and exporters worldwide. With 330.53 Million Tonnes of foodgrain output predicted for 2022–2023, our nation is a far cry from the 1950s and 1960s. We still behind other developed nations, notwithstanding our gains in production. It is acknowledged that a number of issues prevent Indian agriculture from reaching its full potential. Small land holdings, insufficient irrigation, a lack of technological assistance, and difficult financing access are a few of these. Crop health, however, is a significant obstacle to Indian agriculture that frequently goes unnoticed.

The Agromet/Livestock advisories are issued on the basis of weather forecasts made at the meteorological centers. These forecasts are made by numerical methods which employ the process of solving the equations governing the motion of the air. For solving the equations, observations of various meteorological parameters such as pressure, temperature, wind direction and speed and other weather variables are required. The observations are taken at specified times called synoptic hours in all the observatories located throughout the World. The instruments used to measure the weather parameters are housed in the observatory. Instruments used for the measurement of different elements are given below:

Introduction

Libraries are universally recognized as important social institutions for diffusion of knowledge and information. The modern and highly equipped libraries are found in the universities since they are the centers of higher education, training and research. The universities libraries are essential to achieve the objective of university education and research.

1. Introduction

The aim of social networking sites is to build and maintain social interactions through content creation and communication within networks. However, academic social networks have a different focus. It prioritizes facilitating research and academic importance by connecting research groups and their scholarly outputs more effectively.These platforms typically offer features such as personal academic profiles, connections based on shared academic interests, and tools for managing and monitoring one's research outputs. Additionally, they enable users to utilize the research outputs of others in their f ield to advance their work. This study focus on to evaluate the capabilities of prominent academic social networking sites in meeting the essential requirements of researchers and the academic community(Bankar & Lihitkar, 2021)

Teaching

Extension teaching denotes a structured process aimed at fostering the learning experience. This process encompasses the facilitation of activities, provision of materials, and offering guidance necessary for the learner. In essence, it orchestrates scenarios wherein the subjects to be assimilated are brought to the learners’ attention, fostering their interest, engendering desire, instilling conviction, prompting action, and ensuring satisfaction.

Characteristics of Teaching

1. The quintessential objective of teaching transcends mere dissemination of information; rather, it endeavors to effect transformative changes in behavior.

2. Teaching is deemed efficacious only when learning is effectively acquired by the learner.

3. Teaching, analogously, is akin to illuminating a lamp rather than merely f illing a receptacle.

4. Teaching is a deliberate, purposeful endeavor, not a haphazard undertaking.

5. Effective teaching is methodically executed according to predetermined designs rather than being subject to inadvertent deviations.

6. Proficient teaching necessitates meticulous planning encompassing content, procedures, methods, and techniques.

7. Superlative teaching fundamentally hinges upon adept communication, which, in turn, demands empathetic sharing and lucid exposition.

Introduction

The oceans account for 72% of Earth's total surface area and sustain the lives of billions of people. The oceans contain an abundance of both living and nonliving materials, and their depths contain aspects that have yet to be discovered. The oceans significantly affect our everyday weather and climate patterns, as well as the quality of the air we breathe and the water we drink. At this time, our understanding of the oceans is limited to relatively shallow depths. Exploration of the deep sea, which requires specialized modern equipment that is not commercially accessible at the moment, is necessary due to global security concerns involving oceans.

Introduction to Molecular Markers in Vegetable Breeding
As global demand for food continues to rise, the agricultural sector faces mounting challenges from climate change and resource limitations. These pressures necessitate an urgent transformation in farming practices, making molecular markers vital for enhancing crop improvement strategies (Tester and Langridge, 2010). Traditional breeding techniques, which often rely on phenotypic selection and protracted breeding cycles, find it increasingly difficult to produce resilient, high-yield cultivars (Bernardo, 2016). Molecular markers, including Single Nucleotide Polymorphisms (SNPs), Simple Sequence Repeats (SSRs), and Amplified Fragment Length Polymorphisms (AFLPs), provide direct access to plant genomes, allowing for the precise identification and manipulation of desirable traits regardless of environmental variability (Varshney et al., 2005). This approach is essential for expediting breeding programs and enhancing genetic gains, ultimately leading to crops better suited for diverse and evolving climates (Jannink et al., 2010).Additionally, the integration of genome-wide association studies (GWAS) and genomic selection (GS) harnesses high-density marker data to deepen our understanding of complex trait genetics, fostering sustainable agricultural practices and securing future food supplies (Hickey et al., 2019).

Abstract

While, life on Earth is dependent on microbes for many essential services, microbes are intimate partners in virtually every life process of plants by way of mobilization/acquisition of nutrients, out-competition and antagonism of pathogens, plant stress alleviation, plant growth promotion, co-metabolism, degradation of toxins, etc. Exploitation of such interactions between microbes and plants and optimization of plant microbiome could allow farmers to apply less chemical fertilizer, and pesticides besides improving overall plant health which paves the way for sustainable development. What is less appreciated, and less well understood, is the mechanism of microbes exerting such benefits to the plants. A greater understanding of how plants and soil microbes live together, communicate, build innate plant immunity, triggers hormone synthesis and benefit each other can therefore provide new strategies to improve plant productivity, while helping to protect the environment and maintain global biodiversity.

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
Aquaculture has significantly contributed to the increase in global fish production. However, the domestication of only a limited number of species for intensive aquaculture has been achieved in recent decades. A primary challenge in the domestication and sustainable culture of candidate species lies in the standardization of induced breeding techniques. Controlled reproduction in captivity remains suboptimal for many commercially important aquaculture species. In captivity, females of several species often fail to complete oocyte maturation (Corriero et al., 2021), while males exhibit inadequate milt production (Zohar et al., 1989; Peter et al., 1993). Hormonal manipulation and environmental stimulation are considered effective approaches to overcome these challenges and facilitate captive maturation for induced breeding.
Several hormone analogues, such as gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone-releasing hormone (LHRH), have been developed into commercial formulations like Ovaprim™, Ovatide™, and Wova-FH™, which target the brain-pituitarygonad (BPG) axis. However, these hormones have shown limited efficacy in the induced breeding of some commercially important species, including catfish. Recent studies suggest that neurohypophysial nonapeptide hormones also play a crucial role in modulating the GnRH– onadotropin (GTH)–steroid hormone pathway (Joy and Chaube, 2015). In mammals, nonapeptides include oxytocin (OT) and vasopressin (VP), which are homologous to isotocin (IT) and vasotocin (VT) in teleost fish. These nonapeptides, consisting of nine amino acids, are classified as basic (VT and VP) or neutral (OT and IT), depending on the amino acid at the eighth position. For example, VP has arginine, whereas OT has leucine at this position (Stoop, 2012).
In Heteropneustes fossilis, a novel neuropeptide gene, savetocin, has been identified, distinguished from IT by the substitution of valine for isoleucine at the eighth position. Nonapeptides also have homologues in other organisms, such as annetocin in worms and insects, inotocin in mollusks, and conopressin in leeches and Lymnaea stagnalis. Among vertebrates, lungfish, amphibians,
reptiles, and birds produce mesotocin and vasotocin, whereas marsupials secrete oxytocin and phenypressin (Darlison and Richter, 1999). These findings highlight the diversity and evolutionary significance of nonapeptides,
as well as their potential as novel targets for improving induced breeding in
aquaculture species.

Spermatozoa, the male reproductive cells, play a crucial role in fertilization and subsequent embryonic development. However, toxic substances such as heavy metals(lead) can disrupt spermatozoa function through various mechanisms, including oxidative stress, DNA damage, and disruption of cellular homeostasis. The toxic effects can impair sperm motility, viability, and acrosomal integrity, ultimately leading to reduced fertility. Livestock are not immune to these toxic insults, which can compromise their reproductive efficiency and agricultural productivity. Lead (Pb) is a toxic pollutant and is extensively distributed in the environmental and biological systems. This topic envisages the detrimental effects of lead on spermatozoa functions, shedding light on the underlying mechanisms, signal transduction pathways, and sperm kinematic alterations.

Unsupervised classification is the technique of classification of raster data in which no prior information is provided by the user. Raster data is classified based on their spectral characteristics such that the pixels having similar spectral properties in the multispectral feature space are grouped together in one class. Unsupervised classification is mainly performed by clustering algorithms. The purpose of these algorithms is to minimize within cluster variability and maximize between clusters variability. The user must interpret and label the classes after performing unsupervised classification. This method of classification requires minimum data which makes it easy and quick, but user has toput efforts in identification of the classes. This method could be useful when user doesn’t have any prior knowledge about the study area. This method removes subjectivity and enables us to get the unique classes which might be unrecognized by the user. K-means is the most commonly used method for performing unsupervised classification. In this chapter, we have discussed K- means, CLARA and unsupervised random forest method for classification of raster data in R.

SYNOPSIS

The availability of food is of paramount importance without which it is hard for human beings to survive. The recognized way of making food available is to produce but it is also equally important that food produced is utilized well without loss of edible food materials. The paper discusses on unused food, under- utilized food within and across countries, and puts emphasis on utilization and handling of food. In perspective, the paper highlights the steps to be taken up to save and utilize the food already produced.

Globally, antimicrobial resistance (AMR) is an important public health and development threat (WHO, 2020). Being one of the top 10 global public health threats, the ever-increasing rates in the occurrence of drug-resistant bacterial infections have become a grave public health concern for the governments (Laxminarayan et al., 2013). Moreover, such infections would be difficult to treat and therefore can lead to worse clinical outcomes (Laxminarayan et al., 2013). Worldwide, each year about 700,000 people die from antimicrobial resistant infections and the mortality figures are projected to reach 10 million/ year by 2050 (O’Neill, 2016). The crude infectious disease mortality rate in India is more than 400 per 100,000 persons and at least 23,000 deaths in adults and 58,000 neonatal deaths per year are caused by AMR bacteria (Laxminarayan and Chaudhury, 2016). A 2017 estimate puts the cost of developing an antibiotic at around US$1.5 billion (Towse, et al. 2017). Meanwhile, industry analysts estimate that the average revenue generated from an antibiotic’s sale is roughly $46 million per year. “That’s tiny and nowhere near the.

Vegetable crops stand as pillars of global food security and human health, providing essential vitamins, minerals, and dietary fiber crucial for well-being. Their diverse forms, flavors, and nutritional profiles contribute significantly to balanced diets worldwide. However, the successful cultivation of these vital crops is intricately linked to the surrounding atmospheric environment. This
book, “Agroclimatology of Vegetable Crops: Classification and Cultivation” endeavors to explore and elucidate this critical relationship, providing a comprehensive understanding of how climate and weather influence the growth, development, yield, and quality of a wide array of vegetable crops. The interaction between vegetables and their climate is a dynamic and multifaceted one. From the moment a seed germinates to the final harvest, every stage of a vegetable plant’s lifecycle is profoundly impacted by factors such as temperature, precipitation, solar radiation, humidity, and wind. Understanding these influences is no longer merely academic; in an era marked by increasing climate variability and the urgent need for sustainable agricultural practices, it has become a fundamental necessity for ensuring consistent and reliable vegetable production (Fig. 1.1).
Within these pages, readers will find detailed analyses of
• Fundamental Climatic Parameters and Their Impact: A thorough examination of how temperature regimes, rainfall patterns, solar radiation intensity and duration, humidity levels, and wind patterns affect key physiological processes in vegetable plants, such as photosynthesis, respiration, transpiration, and nutrient uptake.

1. Introduction

Academic libraries have traditionally been the cornerstones of academic institutions, serving as repositories of knowledge and centers for learning. In the past, libraries were just regarded as physical repositories of books and other reading material, and their role was to acquire, organize, process, store, and provide access to that physical collection. These traditional libraries were characterized by their emphasis on the preservation of physical collections and the provision of a quiet, contemplative space for study and research. However, the role of libraries has expanded significantly in recent years beyond physical collections to include digital resources such as e-books, online journals, databases, and multimedia content. Modern academic libraries are dynamic and multifaceted, providing not only access to information but also a range of services that support teaching, learning, and research. They have become vibrant hubs of activity, offering collaborative spaces, technology-rich environments, and various programs and workshops that enhance the academic experience. The focus has shifted from merely preserving information to facilitating access, promoting information literacy, and supporting the diverse needs of the academic community.

Introduction

The technology behind Internet search engines is advancing quickly, and this has an impact on how individuals find the information they need online as well as how search engines improve their algorithms (N. Zafar et al. 2022). Search engines are playing a prime role in generating leads for businesses (Olbrich and Schultz, 2014), Because of this, search engines are regarded as the most recent online communication channels for dynamic marketing (Olbrich and Schultz, 2014). To examine how academic institutions (in higher education) use the web to facilitate student relations and identify how prospective students are using the Internet to research academic institutions, Will et al. conducted a study that involved the analysis of more than 3000 university websites. The web continues to be the primary research resource for prospective students, counselors, and parents. The research was undertaken (Sampath Kumar and Kumar, 2013) to determine whether or not academics utilized search engines to access scholarly content from the internet. 285 (95%) of the 300 respondents used search engines to find academic content, compared to just 5% who didn’t. To access the Ed-tech companies that are playing a role in academia, comparable assessment is crucial.

This book, “Meteorology and Geography” is designed to equip aspiring fisheries professionals with a foundational understanding of the atmospheric and terrestrial processes that profoundly influence aquatic ecosystems and, consequently, the distribution, abundance, and health of fish and other commercially important species. For too long, the study of fisheries has sometimes been perceived as largely focused on the biology and ecology within the water itself. While these aspects are undeniably vital, the reality is that aquatic environments are not isolated entities. They are inextricably linked to the atmosphere above and the land surrounding them. The weather patterns we experience daily – from sunshine and rainfall to storms and temperature fluctuations – directly impact the physical and chemical characteristics of our oceans, lakes, and rivers. Similarly, the geographical landscape, including topography, soil composition, and coastal features, plays a critical role in shaping these aquatic habitats. Consider for a moment the seemingly simple act of rain. Rainfall over land influences river discharge, bringing nutrients and sediments into freshwater and coastal systems. Changes in salinity, turbidity, and nutrient levels can dramatically alter the suitability of these waters for different fish species. Strong winds can drive ocean currents, upwelling events that bring nutrientrich deep waters to the surface, and the dispersal of fish larvae. Extreme weather events like cyclones and floods can cause devastating impacts on both wild and aquaculture-based fisheries. Furthermore, the broader geographical context dictates the regional climate, influencing long-term patterns of water temperature, precipitation, and wind. These climatic conditions, in turn, determine the types of aquatic ecosystems that can thrive in a particular area and the species that inhabit them.5 Understanding these geographical controls is essential for predicting the potential and limitations of fisheries in different regions.

Introduction

Agriculture forms the bedrock of the Indian economy, employing over half of the country's workforce and contributing significantly to its GDP. Despite the rise of other sectors, agriculture remains vital for ensuring national food security and the livelihood of millions of farmers. However, Indian farmers face several challenges, including volatile market prices, unpredictable weather patterns and high input costs (Chintapalli and Tang, 2021). In this context, the MSP scheme emerges as a crucial government intervention aimed at safeguarding farmers’ incomes and promoting agricultural stability. According to the latest data from the Ministry of Agriculture and Farmers Welfare, the agricultural sector contributes around 15-18% to India's GDP. While this share has decreased somewhat with the expansion of other sectors, agriculture still sustains the livelihoods of over 54% of the workforce, primarily concentrated in rural areas. Furthermore, India ranks as a leading producer of various agricultural commodities, including pulses, cotton, milk, and rice. This highlights the sector's critical role in ensuring domestic food supplies and contributing to global food security (Mahto and Patil, 2023).

Despite its significance, Indian agriculture faces several challenges. One of the most significant concerns is price volatility. Agricultural produce is often subject to fluctuations in market prices, leaving farmers vulnerable to distress sales during periods of surplus production. Additionally, unpredictable weather patterns due to climate change can significantly impact crop yields, leading to income losses for farmers. Furthermore, the rising costs of essential inputs like fertilizers, pesticides and seeds put a strain on farmers' profit margins (Aditya et al?, 2017). These factors combined create a situation of uncertainty and economic hardship for a vast section of the rural population. The MSP scheme was introduced by the Government of India in the 1960s as a critical policy intervention to address the challenges faced by farmers. MSP acts as a f loor price for certain agricultural commodities, below which the government guarantees to procure produce from farmers at pre-determined prices.

Social institutions encompass a cohesive array of norms that uphold fundamental societal values. It refers to a structured system of social relationships that encapsulates shared values and protocols, fulfilling specific societal requirements. According to Horton, it embodies common values and procedures, addressing the fundamental needs of a society. These institutions are formal cultural frameworks designed to satisfy essential social needs and establish organized patterns of human behavior in the execution of core societal functions

Social institutions emerge from societal interactions to address fundamental needs such as stability, law enforcement, and the delineation of authority and decision-making roles. Each organization operates within established sets of rules, traditions, and customs, collectively termed as institutions. These institutional frameworks consist of recognized procedures and norms that are accepted by society, regulating interactions and relationships between individuals and groups.

Nanotechnology has emerged as a revolutionary force in the food industry, providing innovative solutions to improve food quality, safety, and usefulness. Researchers have devised novel ways to numerous issues in food production and preservation by harnessing nanoparticles' unique traits, such as their high surface area-to-volume ratio and customizable physicochemical characteristics. Nanotechnology-enabled food additives provide a wide range of benefits, including improved texture, taste, color, and nutritional value, as well as increased shelf life and microbiological safety. Furthermore, nanoparticles are effective transporters for bioactive chemicals, allowing for targeted and regulated release within the food matrix.

Personality, a term deeply ingrained in our everyday discourse, encapsulates the essence of what makes individuals unique. This multifaceted construct has intrigued scholars, philosophers, and psychologists alike throughout history. Its exploration not only delves into the intricacies of human nature but also seeks to unravel the complexities of individual differences and behavior.

The journey to understand personality spans millennia, with its roots tracing back to ancient civilizations. Early philosophical inquiries by thinkers such as Plato and Aristotle pondered the nature of character and temperament, laying the groundwork for later conceptualizations. However, it was not until the late 19th and early 20th centuries that personality garnered significant attention within the realm of scientific inquiry. The emergence of psychology as a distinct discipline heralded a new era of systematic study into the intricacies of human behavior and individual differences. Influential figures like Sigmund Freud, Carl Jung, and Alfred Adler pioneered seminal theories that sought to elucidate the dynamics of personality development, the unconscious mind, and the interplay of internal drives and external influences.

8.1 Introduction
The increasing rate of waste generation due to consumption patterns has emerged as a significant environmental management challenge. The valorization of this waste hold great potential in production of bio-based products, provided they meet the multi-criteria of environmental sustainability and economic viability (Dragone et al., 2020). Within this framework, the advancement of biorefineries is considered to be a valuable strategy. These transform lignocellulosic biomass to valuable bio-based products including biofuels and biobased chemicals which promote circular economy (Mariana et al., 2021). The incorporation of biorefineries into the market value chain necessitates the establishment of production framework which aims high recovery and generation of value-added products from biomass (Meramo- Hurtado and González-Delgado, 2019). However, the upscaling of these biorefineries faces various challenges such as process efficiency and technological advancement. Additionally, the largescale operation of biorefineries requires consistent and stable biomass supply. Addressing these challenges require technological advancements and policy framework (Makepa and Chihobo, 2024). These could ensure the economic viability and profitability of biorefineries which is essential for their successful implementation in long-term sustainability goals (Arias et al., 2023). In this context, the early-stage evaluation comprises production capacity, market demand, technological limitations and environmental impact.
8.2 Challenges in Upscaling of Biorefineries
For fulfillment of the global demand for bio-based products it is important to upscale biorefineries from laboratory to industrial scale. Biorefineries are closely aligned with the United Nations Sustainable Development Goals (SDGs), as several SDGs emphasize the efficient and circular utilization of resources to promote sustainability. Additionally, SDSs promotes adoption of practices which encourage climate change mitigation, economic growth, societal well-being and advancements in research and innovations (Lange et al., 2021). However, the establishment of biorefineries faces various technical challenges similar to those encountered in conventional refinery plants. These challenges arise primarily due to the large volume of biomass required for processing to achieve industrial scale production of bioproducts (Ahmed et al., 2023).

Wind stress at the sea surface not only causes horizontal movement of water (Ekman Net transport), but also leads to vertical motion (Ekman Pumping). This horizontal movement of water leads to the occurrence of upwelling and down welling throughout the oceans both at coastal boundaries as well as in the open ocean. As divergence of surface water causes rising, convergence of the surface water causes sinking. This rising and sinking of water are called upwelling and down welling.

ABSTRACT

The multi-sensor airborne geophysical survey was carried out over Nalgonda district, Andhra Pradesh, during the field season 2002-03, with an objective to locate potential areas for mineral exploration. The area comprises older metamorphic rocks of Peninsular Gneissic Complex of Archaeanage represented by gneisses, granite, amphibolite and banded magnetite quartzite. Leucocratic intrusive granite, extending over a length of about 40 km around Suryapet in NNW-SSE direction exhibits intense fracturing. Two sets of vertical to sub-vertical fractures have been noted in granite. Yellow stains observed in granite near fracture planes reveal the presence of secondary radioactive mineral encrustation. The ground magnetic and spectrometric observations indicated that the uranium mineralization is confined to these fractures in granite. Petrographic, ore-microscopic and scanning electron microscopic studies revealed evidences of metamict alteration surrounding monazite/apatite inclusions within biotite, and magnetite grains in granite. These studies also indicated evidences of discrete grains of uraninite / coffenite / pitchblende (containing Thand Ce). Chemical analysis of the rock samples (by NAA) collected from anomalous zone reveal high uranium concentration of the order of 1200 ppm, marked by high values of total Rare Earth Element concentration (800 ppm).

The leucogranites are characterized by high LREE and a negative Eu anomaly suggesting plagioclase fractionation. An ultramafic enclave near village Kutubsahipur shows highest concentration of both uranium (1240 ppm) and REE (890 ppm) analyzed by BARC and NAA Lab, GSI.

Urban agriculture is gaining prominence as a viable solution to numerous challenges faced by modern cities, including food security, environmental sustainability, and community well-being. This comprehensive article explores the concept of urban agriculture, its historical development, and its various forms and practices. It examines the benefits of urban farming, such as enhanced food security, reduced food miles, and improved urban environments, while also addressing challenges like space constraints and regulatory issues. Case studies from cities worldwide illustrate the successful implementation of urban agriculture. The article concludes by discussing future trends and the potential of urban agriculture to transform urban landscapes into productive, sustainable, and resilient communities.

SYNOPSIS

This millennium has brought about serious challenges as well as excellent opportunities for the betterment of humanity. The migration of rural population to urban areas is one of the major challenges foreseen. It is expected that much of the population growth is expected to take place in the cities of the developing world. By 2020, about 52 percent of the developing world’s population will be living in urban areas (IFPRI, 1999). The agricultural areas around cities offer great promise to urban and peri-urban agriculture.

The interventions on Urban and Peri-urban Agriculture (UPA) suggested and initiative undertaken by FAO is timely and valuable in the interest of the teeming population demanding for both nutrition and health. The International Conference on Vegetables (ICV-2002) held during 2002 has emphasized the importance of vegetables; FAO International Workshop on Urban and Peri-urban Agriculture for Asian Countries organized during 2005 had amply emphasized the important role of horticulture; and the International Conference on Horticulture (ICH-2009) held during 2009, has amply illustrated the importance of horticultural crops particularly vegetables in UPA for the benefit of urban population.

The urbanization process is a reality that drives people to go and live in the cities. It is very pronounced in Latin America where already 85% of the population lives in cities; in Asia the average is reaching 60% whereas in Africa the phenomenon has started later and has now reached 35%. Besides the increased demand for food, there has been a rapid increase of poverty, unemployment, hunger and malnutrition in the Urban and Peri-urban environment around the world that are of great concern to central and municipal authorities.

UPA can contribute to feeding the urban population, generate income and employment and thereby reduce poverty. In reality many countries have already UPA related activities going on in areas of horticulture including vegetables, dairy production, small livestock, aquaculture and forestry. However, it has been realized that very few countries had actually investigated the real opportunities and constraints linked to the urban agriculture sector.

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

The relentless march of urbanization, coupled with the growing uncertainties of a changing climate, casts a long shadow over the water security of our cities. Unlike their rural counterparts, urban areas face a distinct and often amplified set of challenges when drought strikes. The intricate web of municipal water supply, the concentrated demands of industry and commerce, and the sheer density of population render urban centers particularly vulnerable to the cascading impacts of water scarcity. When the taps run dry or restrictions tighten, the repercussions extend far beyond parched lawns and wilted gardens, impacting public health, economic stability, and the very fabric of urban life This chapter serves as an entry point into the critical field of urban drought management. We will delve into the unique characteristics that distinguish urban droughts from their rural counterparts, highlighting the interconnectedness of water systems and the amplified socioeconomic consequences within city limits. We will explore the increasing frequency and intensity of these events, driven by both natural climate variability and

Normally we associate our agriculture and food supply with farms and villages. The new trends of greener cities and urban and peri urban horticulture (UPH) are emerging very fast. Towns and cities in the world’s developing countries are growing at great speed. Ten years ago, an estimated 40 percent of the developing world’s population or 2 billion people lived in urban areas. Since then, their numbers have expanded twice as fast as total population growth, to more than 2.5 billion. By 2025, more than half the developing world’s population of 3.5 billion will be urban. Again most of the world’s fastest growing cities are in Asia and Africa with young population.

However, the core principles of Greener Cities can guide urban development that ensures food security, clean environment and economic well being. Urban and peri-urban horticulture, together with eco-friendly home and public gardens and sports fields can offer a solution for a better future.
Greener Cities and Eco Agriculture
FAO’s program for UPH is major initiative and the following advantages and plans taken from FAO’s report make the reasons clear : Urban and peri-urban horticulture (or UPH) is the cultivation of a wide range of crops - including fruit, vegetables, roots, tubers and ornamental plants - within cities and towns and in their surrounding areas. It is estimated that 130 million urban residents in Africa and 230 million in Latin America engage in agriculture, mainly horticulture, to provide food for their families or to earn income from sales. The FAO program have demonstrated how horticulture helps empower the urban poor, and contributes to their food security and nutrition. But it can

Trees are major capital assets in cities Just as streets, sidewalks, public buildings and recreational facilities are a part of a community’s infrastructure, so are publicly owned trees. Trees — and, collectively, the urban forest — are important assets that require care and maintenance the same as other public property. Trees are on the job 24 hours every day working for all of us to improve our environment and quality of life. Urban forest provides many environmental benefits to our community. Aside from the obvious aesthetic benefits, trees within our urban forest improve our air, protect our water, save energy, and improve economic sustainability.

In other words, since most trees have been planted much of the tree cover is in urban areas as opposed to “natural lands”. Therefore, estimated pollutant uptake rates are higher for residential compared to natural or unmanaged lands. Possible management implications of these estimates are that air pollutant uptake benefits from tree planting may be optimized by planting in areas where air pollutant concentrations are elevated and where relatively high planting densities can be achieved thereby enhancing the health of urban dwellers.

Urban forestry is not a new concept, but it is one which appears to have growing potential. With increasing urbanization in the 20th century, the incorporation of trees into urban settlements has also increased. The management of all trees within the urban area is considered a distinct discipline of forestry. Urban forestry was conceptualized in the late 1960s in North America, and grew out of what was initially termed environmental forestry. Trees and urban forests can make our cities cleaner, cooler, greener, safer, healthier, happier and nice places to live.

Introduction

A subfield of horticulture known as “urban horticulture” is concerned with the care, maintenance, and use of plants in urban settings. Urban gardening encompasses a broad range of plant life, from ornamental plants to trees, shrubs, flowers, vegetables, and even fruit trees.

Plants, both ornamental and edible, are the specialty of urban horticulture, a subfield of horticulture concerned with their care and production in urban and peri-urban settings. Horticulture is the study and practice of growing plants for their aesthetic and functional value in urban and suburban settings.The practice of urban horticulture includes all aspects of creating and maintaining urban gardens, parks, and other green areas. The practice of urban horticulture entails improving the visual, ecological, and recreational qualities of built environments through the deliberate selection, placement, and ongoing care of plants.

India has experienced rapid urbanization as well as industrialization since independence. Though, the country has achieved considerable progress in industrial growth as well as expansion of urban and town spread, the land available in urban periphery as well as near big rivers are being utilized for non agriculture purposes. Similarly, for the development of road, rail as well as irrigation infrastructure, the government reserved huge land, which was under cultivation of various crops. The non agricultural businesses became more remunerative near cities and has increased the value of land near cities; which is not affordable for agriculture production. Considering the limitation of land for production purposes in urban areas, the concept of Urban Horticulture was conceived.

Urban local bodies refer to the local government institutions that are responsible for the administration and governance of urban areas. These bodies are established to address the specific needs and challenges of urban areas, including cities, towns, and other urban settlements. Urban local bodies play a crucial role in managing urban infrastructure, providing essential services, and promoting urban development. They are responsible for areas such as urban planning, public health, sanitation, solid waste management, transportation, water supply, and housing. The composition and structure of urban local bodies vary across different countries and regions, but they typically consist of elected representatives who work towards the overall development and well-being of urban communities.

Urban climatology deals with changes in climatic conditions that prevail in large cities and towns that differ from the surroundings. Urban climates are influenced by large built-up areas, increased human activities and dense population and are found to experience differences in temperature, humidity, wind speed and direction and rainfall compared to adjoining areas. Tall buildings, paved streets and parking lots affect radiation balance, wind flow and run-off. The atmosphere in urban areas will have higher concentration of pollutants like carbon monoxide, oxides of sulphur and nitrogen, hydrocarbons, oxidants and particulate matters. Heavy concentration of air pollutants will have considerable impact on temperature, humidity, wind, and precipitation in and around urban areas. Heavy concentrations of air pollutants for longer periods or several days may lead to temperature inversions. The temperature inversions prevent convection and vertical movement of air. The centre of urban area will be warmer by even 5 to 6°C compared to adjoining areas. During summer months, the concrete structures absorb, store and reradiate more solar energy per unit area compared to vegetation. During nights, radiative losses from urban buildings and roads keep city warmer than the rural areas. The average relative humidity in cities is usually lower due to lack of evapotranspiration from vegetation. The mean wind speed will be 20 to 30 percent due to increased frictional drag induced by built up urban terrain (Fig.17.1).
The urban areas influence precipitation patterns in its vicinity as turbulence and convection get modified by city environment.
17.1. Urban Heat Islands
An urban heat island is a type of microclimate that is created when an urban area becomes warmer than the surrounding area. It is common in large cities (Fig.17.2). The characteristic features of urban heat islands are as follows:
• Increased temperature
• Large temperature difference by even 5 to 6°C
• The south facing buildings receive more sunlight in the northern hemisphere
• The tall buildings in urban areas create streets that act like deep valley
• The albedo will be very less. The darker areas lead to more absorption of incoming solar radiation and emit more of long wave radiation
• The concrete structures are built with materials having low specific heat. Therefore, concrete structures warm up faster and lead to quick rise in temperature
• The higher density of buildings reduces wind speeds.

Introduction
Urban sustainability has become a critical focus as the global population increasingly concentrates in cities. With over 56% of the world’s population residing in urban areas, cities are significant drivers of economic growth and innovation but also contribute disproportionately to environmental degradation, resource depletion, and social inequities. Urban sustainability aims to balance economic, social, and environmental dimensions, ensuring that cities are livable, resilient, and capable of meeting the needs of current and future generations. Information Technology (IT) is pivotal in advancing urban sustainability by enabling smarter resource management, reducing environmental footprints, and fostering inclusive and equitable development.
