“Sustainable Water Resources Management Strategies” embarks on a comprehensive exploration of the paramount challenges and essential solutions for safeguarding our planet’s most precious resource: water. This recognizes that water is not merely a commodity but the very lifeblood of ecosystems, a cornerstone of human health, a critical input for food production, and an indispensable element for industrial progress and societal well-being. Building upon a fundamental understanding of the intricate hydrological cycle, the distribution of global water resources, and the escalating anthropogenic pressures they face, we now turn our attention to the proactive and forwardthinking approaches that define sustainable water resources management. • In an era marked by increasing environmental consciousness and the stark realities of climate change, the traditional paradigms of water management are proving inadequate. Growing populations, rapid urbanization, and the expansion of industrial activities place unprecedented demands on both the quantity and quality of available water. Furthermore, the erratic and often extreme

Introduction Organizational structure and management represent fundamental dimensions of community mobilization that determine how collective efforts are organized, coordinated, and sustained over time while building institutional capacity for effective action and long-term development success. The design and implementation of appropriate organizational arrangements significantly influence the ability of community groups and development organizations to achieve their goals while maintaining community ownership, democratic participation, and adaptive capacity that can respond to changing circumstances and emerging opportunities. The complexity of contemporary community challenges requires sophisticated organizational approaches that can coordinate diverse activities and stakeholders while maintaining flexibility and responsiveness to local conditions and community preferences. Effective

Agriculture, the cornerstone of human civilization, is intrinsically linked to weather and climate. The success of crop production hinges significantly on the prevailing meteorological conditions, which dictate every stage of a plant’s life cycle, from germination and emergence to growth, flowering, and ultimately, yield. Understanding the intricate relationship between weather elements and specific crop requirements is paramount for maximizing agricultural productivity, ensuring food security, and developing resilient farming systems in the face of a changing climate. This chapter delves into the critical role that various weather parameters play in shaping crop performance. We will explore how factors such as temperature, precipitation (rainfall), sunlight (solar radiation, intensity, duration, and quality), humidity, and wind velocity interact to create the ideal environment for different crops. While plants possess an inherent adaptability, each crop species, and often even individual cultivars, has a specific range of “cardinal temperatures” (minimum, optimum

The intricate dance between life and its atmospheric surroundings has shaped every living organism on Earth. From the microscopic bacteria thriving in extreme environments to the complex physiological systems of humans and large animals, weather and climate are not merely backdrops but active, pervasive forces dictating survival, distribution, behavior, and health. Weather, representing the short-term atmospheric conditions we experience daily— temperature, humidity, precipitation, wind, and sunlight—directly influences immediate comfort, activity levels, and susceptibility to acute events. Climate, on the other hand, embodies the long-term patterns and averages of these atmospheric variables over decades or centuries, acting as a fundamental determinant of ecosystems, biodiversity, and the sustained well-being of populations. This chapter delves into the multifaceted ways in which these atmospheric phenomena exert their influence. We will explore how thermal conditions drive physiological responses, from metabolic rate adjustments and thermoregulation to the very limits of endurance in extreme heat and cold. Beyond direct physiological impacts, we will examine the indirect effects, such as the role of climate in shaping

1. Introduction
One of the foremost environmental challenges the world faces today is airpollution. As industrialisation, urbanisation, and transportation continueunabated, harmful substance levels in the atmosphere have becomealarmingly high (Thanvisitthpon et al., 2024). This general contamination inthe air is not just a serious risk to humanity but also harms ecosystems whilcontributing to global climate change. Controlling airpollution has becomea critical necessity at this stage, with the need for innovative solutions inthis respect. Bioremediation is one of the innovative solutions, where certainmicroorganisms break down or neutralise pollutants in the air.

1.1. The Growing Problem of Pesticide Pollution
Pesticides are used in very great amounts in agricultural production for theprotection of crops against pests, diseases and weeds. They are also veryinstrumental in boosting agricultural productivity by ensuring food securityand preventing losses that may be caused by outbreaks of pests (Popp et al.,2013). However, the extensive use of pesticides has generally resulted in hugeenvironmental concerns. Improperlymanaged pesticide residues may remainin soil, water and even air for many years and create severe ecological andhealth hazards in the long run (Zhang et al., 2024). This widespread existenceof pesticides in the environment has raised a serious alarm concerning theiradverse impacts on biodiversity, soil fertility and quality of water, furtherbioaccumulation in the food chain that affects wildlife and human populations(Aktar et al., 2009).

2.1 Mulkanoor Cooperative Society: An Introduction The Mulkanoor Cooperative Rural Credit and Marketing Society, established in 1956, in Mulkanoor village of today’s Telangana state of India, stands as a beacon of rural transformation. Post-independence, Shri A.K. Vishwanatha Reddy- a freedom fighter- envisioned a better future for farmers. His vision materialized through the formation of the Mulkanoor Cooperative Society, initially with 373 members and a modest share capital of ?2,300. The society has now grown to encompass 7,650 members, ?18 crores in share capital, and ?45 crores in thrift deposits, and offers a wide

Making a correct and an early diagnosis is very much important for undertaking rational and effective treatment for fast recovery, avoiding unnecessary medication, reducing the load of so many drugs on body metabolism, reducing environmental pollution and the cost of treatment. There are four important pillars for making a correct diagnosis viz. the history, the systematic clinical examination, the correct clinical diagnostic techniques and the laboratory support. History Taking Clinician’s first step in making a diagnosis is through asking the owner’s complaint. Accurate and complete history may be obtained from focusing on the details of the patient (name, number, species, breed, age, sex and weight), vaccination status, deworming schedule, nutritional history, past and present medical history and environmental history.

Farm Animals and Horses Urinary system mainly comprises of kidneys, ureters, bladder and urethra. In farm animals, diseases of urinary bladder and urethra are diagnosed with more frequency than that of kidneys. Renal insufficiency is observed as a sequel in cases of nephritis (pyelo or embolic nephritis), nephrosis or amyloidosis. Urinary diseases are clinically manifested with pain, dysuria, and variation in urine flow (polyuria, oliguria to anuria) and changes in urine (proteinuria, hematuria, hemoglobinuria, myoglobinuria, glycosuria, ketonuria, crystalluria, pyuria, and cellular casts). Decreased body weight, loss of appetite, polyuria, polydipsia and ventral edema are seen in chronic renal failure. Like dogs and cats, urinary tract is not accessible in large farm animals for clinical examination. Trans abdominal palpation of kidneys is feasible in calves and small ruminants. Rectal palpation, urine examination and renal function tests provide diagnostic assistance in the diseases of urinary tract in large animals. Clinical Manifestations Dysuria and abdominal pain are generally seen in urinary tract disease. Acute pain from urinary tract disease is not common. Pain associated with urethral obstruction and bladder

Cardiovascular examination provides essential information about cardiac function, circulation and vascular abnormalities. This chapter describes practical examination techniques including inspection, palpation, percussion and auscultation of the heart and peripheral circulation. Assessment of the cardiac impulse, heart sounds, murmurs, pulse quality, jugular veins and blood pressure contributes to identification of cardiovascular abnormalities. Electrocardiography is presented as an important diagnostic technique, including electrode placement and interpretation of standard leads. Echocardiography is also introduced for structural and functional cardiac assessment. The chapter provides species-specific practical approaches for cattle, horses and dogs, helping veterinary students recognize cardiovascular abnormalities systematically and accurately

Indian river systems, spanning diverse ecosystems and climatic zones, are pivotal for sustaining the country's rich biodiversity, particularly regarding ichthyofaunal diversity. This chapter explores the ecological importance of major river systems such as the Ganges, Brahmaputra, Godavari, Krishna, and Cauvery in supporting various freshwater fish species essential to environmental balance and local economies. These rivers provide critical habitats and migration routes, facilitating the survival and reproduction of numerous fish species. However, pollution, habitat fragmentation, overfishing, and climate change have led to declines in fish populations and the loss of species diversity. The chapter underscores the importance of integrated conservation strategies that combine river ecosystem restoration, sustainable fisheries, and habitat protection to address these threats. Additionally, it highlights the need for community engagement, policy support, and technological innovations such as environmental DNA (eDNA) monitoring to ensure effective conservation of freshwater fish diversity. Through a comprehensive ecological approach, this chapter advocates for urgent measures aimed at preserving fish species within Indian river systems, promoting biodiversity, and supporting the communities reliant on these resources.

Heart of bovine, caprine, equine, canine and feline is a four chambered organ having left and right atrium, left and right ventricles, mitral valve, tricuspid valve, aortic valve, pulmonary valve, arteries, arterioles, veins and venules. Heart starts its functioning even before birth and continues till death. Its pumping action helps in providing nutrients as well as oxygen to all organs and parts of the body and to remove the waste products of the metabolism from the different organs of the body. Malfunctioning of the heart (pumping action and /or current generation and conduction) adversely affects nutrient and oxygen availability to organs and removal of waste products from the body lowering the quality of life and making the survival reasonably difficult. Heart functioning can be examined through physical examination of the heart such as general inspection (looking for abducted elbow, jugular distension or pulse, edema of ventral abdomen or limbs, tachypnea /dyspnea), evaluations of vitals (temperature, pulse, respiration,

Selection of Identification Method • Depends very much on Need and personal

Remote sensing and Geographic Information Systems provide spatial information for monitoring crops, land, soil and water resources. This chapter introduces their fundamental principles and explains developments involving satellites, UAVs, hyperspectral sensors, thermal imaging and cloud-based geospatial platforms. Analytical techniques include vegetation indices, time-series analysis, spatial modelling and artificial intelligence. Applications cover crop-health monitoring, yield forecasting, irrigation planning, drought assessment, pest and disease identification and soil-resource management. Integration with IoT, automation and other digital technologies improves the timeliness and resolution of agricultural information. These tools support evidence-based decisions responding to food-security, climate-change and natural-resource sustainability challenges.

The emergence of Large Language Models has enabled the development of virtual teaching assistants capable of providing students with continuous, interactive, and personalized academic support. This chapter examines the role of LLM-powered chatbots and intelligent tutors in modern education. Unlike conventional digital resources, AI teaching assistants can engage learners through natural-language dialogue, explain difficult concepts, provide examples, generate practice activities, offer hints, and deliver immediate feedback. They can support individualized learning pathways by adapting explanations and learning materials to student needs, performance, and pace. The chapter explores applications in tutoring, assessment, academic guidance, interactive textbooks, student support, and self-directed learning. AI assistants can also reduce routine teacher workload by supporting activities such as grading, question generation, content recommendation, and classroom analytics. However, challenges remain concerning hallucination, accuracy, privacy, algorithmic transparency, inclusivity, and the appropriate balance between automated assistance and human mentorship. Large-scale and long-term evidence is still needed, particularly in diverse and low-resource educational settings. The chapter therefore emphasizes human–AI collaborative instruction, educator training, ethical integration, and responsible deployment of intelligent teaching assistants.

Inclusive education requires learning environments that recognize and respond to the diverse sensory, physical, cognitive, emotional, and learning needs of students with disabilities. The integration of Generative AI with Assistive Educational Technology and digital pedagogy creates new possibilities for removing longstanding barriers to participation and achievement. This chapter explores how intelligent technologies can provide flexible, adaptive, and personalized learning experiences for disabled students. It examines applications involving text-to-speech, speech-to-text conversion, screen readers, captions, intelligent interfaces, eye tracking, gesture-based controls, AR/VR, multimodal content, real-time feedback, and AI-supported personalization. Generative AI can further enhance conventional assistive technologies by producing customized written, visual, and audio learning materials according to individual requirements. Universal Design for Learning provides an important framework for ensuring that these technologies support accessibility and inclusion rather than creating additional barriers. The chapter also highlights the importance of individualized learning plans, teacher preparation, family and community engagement, emotional support, and stakeholder collaboration. By combining digital pedagogy, assistive technologies, and GenAI, educational institutions can move toward more equitable, accessible, learner-centered environments in which students with disabilities can participate meaningfully and develop their full potential.

The growing adoption of Generative AI in academic institutions has moved the technology from experimental applications toward practical implementation across teaching, learning, research, student support, and university operations. This chapter examines real-world applications and institutional case studies that demonstrate how GenAI can be incorporated into higher education and other academic environments. Key applications include AI tutoring and learning support, curriculum and course development, assessment and feedback, research assistance, student-success services, and institutional operations. AI writing coaches can provide individualized guidance, while dialogic mathematics and coding assistants can support problem-solving without simply providing answers. Educators can use GenAI to develop learning objectives, case studies, examples, question banks, rubrics, multimedia scripts, synthetic datasets, and practice environments. The chapter also considers institutional experiences with AI policies, academic integrity, accessibility, privacy, and professional development. Successful implementations generally combine technological capabilities with human review, clear institutional guidelines, and AI literacy. Case studies demonstrate both the potential and limitations of GenAI, emphasizing that effective adoption requires contextual evaluation rather than technology-driven implementation alone. The chapter provides practical insights for institutions seeking evidence-based and responsible approaches to educational transformation through generative AI.

The increasing deployment of Large Language Models across education, healthcare, finance, employment and public services has made fairness and ethical responsibility central concerns in AI development. LLMs learn from enormous datasets that may contain historical inequalities, stereotypes, cultural assumptions and other forms of social bias. This chapter examines the origins, manifestations and consequences of bias in LLMs and considers approaches for promoting fair and responsible deployment. It discusses data bias arising from the composition and curation of training datasets, algorithmic bias introduced through model architectures and learning processes, and bias associated with human-in-the-loop systems. Gender, racial and cultural biases are considered because they can influence generated outputs and potentially reinforce existing inequalities. The chapter also examines fairness evaluation, mitigation strategies, transparency, accountability and human oversight. Ethical concerns extend beyond bias to hallucination, misinformation, privacy and inappropriate automation. Effective governance requires continuous monitoring rather than one-time assessment because model behaviour may change across applications and populations. The chapter therefore emphasizes responsible AI principles that place fairness, transparency, accountability, safety and human interests at the centre of LLM development and deployment.

Food preservation involves treating and safely handling food to prevent or delay spoilage while retaining colour, texture, flavour and nutritional value. Food deterioration may result from microbial growth, indigenous enzymes, oxidation, physical damage, insects, moisture, temperature and other environmental conditions. Bacteria, fungi and other microorganisms contaminate food through soil, water, air and biological sources. The effectiveness of preservation therefore depends on controlling intrinsic factors such as pH, water activity, nutrients and redox potential, together with extrinsic factors such as temperature, humidity and storage atmosphere. Understanding these mechanisms provides the scientific foundation for selecting safe and effective preservation methods.

Organizations operating in an interconnected global economy must consistently deliver reliable products and services while satisfying demanding customer and regulatory expectations.

Wearable sensors and IoT devices enable continuous monitoring and early-warning systems, supporting preventive veterinary care and outbreak management. AI-based detection can reduce mortality, treatment costs and production losses while improving decision-making. The chapter also evaluates challenges involving inconsistent data, model interpretability, rural infrastructure, technical accessibility and the practical implementation of diagnostic systems.

Animal behaviour provides valuable information about health, welfare, reproduction, environmental adaptation and social interaction. Traditional observation is labour-intensive, time-consuming and vulnerable to observer bias. This chapter explains how machine learning automates behavioural analysis using video, sensor and bioacoustic data. It covers preprocessing, feature extraction, classification, clustering and recurrent neural networks for temporal analysis. Computer-vision techniques—including object detection, tracking and pose estimation—enable continuous and non-invasive monitoring. Case studies demonstrate applications in livestock management, wildlife conservation and laboratory research. The chapter also examines data labelling, model generalization, ethics, explainable AI, real-time processing and the integration of multiple behavioural data sources

Digital dairy farming integrates IoT, artificial intelligence, machine learning, big-data analytics, cloud computing, sensors and automation to improve herd management.

This chapter introduces drones as aerial intelligence platforms capable of collecting high-resolution spatial and spectral information about crops, soil, and environmental conditions. It discusses drone architecture, sensing technologies, remote sensing, crop monitoring workflows, and crop health assessment. Artificial intelligence and machine learning enable efficient analysis of aerial imagery for disease detection, irrigation management, precision spraying, crop stress assessment, and yield prediction. The chapter also examines autonomous drones, drone swarms, IoT integration, edge computing, and digital twins. Operational limitations, regulatory considerations, data management, and sustainability implications are also addressed.

Vegetative propagation enables horticulturists to multiply plants while retaining desirable genetic characteristics of selected mother plants. This chapter covers important methods including cuttings, layering, budding, grafting, division, and specialized vegetative structures. The physiological basis of rooting, wound healing, callus formation, compatibility, and environmental requirements is discussed. Grafting and budding are particularly important for combining desirable scion characteristics with suitable rootstock traits such as vigor, disease resistance, stress tolerance, and adaptation. Proper sanitation and selection of healthy propagation material are emphasized to minimize pathogen transmission. Modern techniques such as rooting hormones, mist chambers, protected propagation, and clonal multiplication further improve the efficiency and uniformity of vegetative propagation.

Introduction

Man’s intervention in the evolution of plants, to adapt them to suit his needs, constitutes the practice of plant breeding. Historically regarded as an art and still too empirical to be accepted universally as a science, it has recently been described as a technology (Riley 1978). Whether art, science or technology, it certainly draws on a wide range of disciplines and embodies all those principles of organisation and management that determine success in any production-oriented programme.

Perhaps the biggest contribution that the plant breeder has made to increased production during the past 50 years has been in helping to alleviate the effects of natural hazards such as lodging, pests and diseases on crop production. While most of this progress has been through the manipulation of biotic stresses, much is still to be achieved under non-biotic stresses such as drought, salinity, temperature, etc. This argument is strengthened by the fact that in spite of the spectacular achievements made possible by the ‘Green Revolution’, the productivity level of most crop plants, including wheat and rice, has remained both low and static under stress conditions. Concerted efforts are needed through an approach of interdisciplinary research, since not much has been done to define criteria for stress assessment and evolving breeding approaches for incorporating stress tolerance in crop plants.

Conservation has always been one of the most important applications of ecology.Unfortunately, the term “conservation” suggest “hoarding”, as if the idea were simply to ration static supplies so that there would be some left for the future. In the eye of the general public the “conservationist” is too often presumed to be an antisocial person who is against any kind of “development”. What the real conservationist is  against  is unplanned  development  that breaks  ecological  as  well as human laws. The true aim of conservation, is two fold–
    
(1)     To ensure the  preservation of a  quality  environment that considers esthetic and recreational as well as product needs; and  
    
(2)     To ensure as continuous yield of useful plants, animals and materials by establishing a balanced cycle of harvest and renewal.

Introduction

The natural hazards like floods, cyclones, droughts, landslides and earthquakes are not rare or unusual phenomenon. India is among the world’s most disaster prone areas and a large part of the country is exposed to such natural hazards, which often turn into disasters causing significant disruption of socio-economic life of communities leading to loss of life and property. It would not be considered as a disaster unless it resulted in actual damage to human life or property. According to data accumulated over past 25 years, natural disasters in Asia accounts for about 40% of the world’s total disasters while the death toll ratio is about 50% and the number of people affected is about 90%. The latter figure is about 2.2 times the ratio of number of occurrences in Asia. The figures vary widely over the decades, a result that can be attributed to a few particularly terrible disasters. Such as the 1976 Tangshan Earthquake in China, which killed about 250,000, and a series of severe cyclones that hit Bangladesh in 1970 with a death toll of about 500,000. The death toll resulting from wind and flood disasters jumped by an order of magnitude in the 1990s. But this sudden increase affected Asia’s ratio to the world total by about 15 percentage points because there was a worldwide surge in this type of disaster. Clearly, there is an extreme concentration of victims of such disasters in Asia, Another substantial increase is clear in the value of damage caused by typhoons and cyclones; it is now running at 10 times the level of the 1980s. Again, however, the ratio has remained almost unchanged, at about 40%, because hurricanes in Central and North America account for more than 50% of the world total (51.2%, 58.5%, and 54.4% in the 1970s, 1980s, and 1990s,respectively). It is sadly worth noting that there has been conspicuous growth in the absolute value of damage in both Asia and the Americas.

Introduction

The Rispana river is a order of stream forming a tributary of Ganga. Its watershed covers an area of approximately 53.6 Km in the northern part of Dehradun city lies between 78^º30’ to 78^º15⁰’ longitude and 30^º15’ to 30^º 30’ latitude in top sheet No is 1/3. The area is covered in IRS - IC Pan of 13 Jan 1998 and LISS-III of 7 March 1997.

The Doon Valley is enriched with numerous seasonal and perennial streams. Which forms the lifetime or the inhabitants . The Rispana river is the part of the Ganga system of Drainage of the valley. The river originates from the Mussoorie hills, which are full of natural springs. The droplets from the springs collect and form numerous streamlets and these streamlets are joined to be these and they form the famous Shekhar Falls (north of Shahanshai Ashram about 5 Km away). Then the Rispana flows along Rajpur road over the Doon Gravels and then river passes through the tiny hamlets Nalapani, Raipur, Chanderroad, Defence colony, Amwala, Tapowan, Dandadhoran Adohiwala, Dalanwala, Gujram, Ajabpur and finally its contribute the water to the suswa River which intern joins the Ganga.

Olericulture, a Latin word, is used to designate the science, culture and management of vegetable crops. In India, about more than fifty vegetable crops are grown in different parts, depending on their climatic requirement. A number of vegetables have similarity in their method of cultivation, which makes the package of practices followed by the farmers for their cultivation very complicated and brings about a lot of repetition. Whichever the method is adopted for the classification of vegetables can systematize the preparation and presentation of the material to some extent and can avoid the unnecessary duplication of some of the principles and methods of vegetable cultivation. In different vegetables, different plant parts are used as food in different forms and they belong to different botanical families with varying cultural and climatic requirements but common insect-pests and diseases along with their common control measures.

Various methods may be used to classify all the vegetable crops into different categories but no single method of classification would be useful to serve the purpose for different groups of scientists like taxonomists, botanists, physiologists, horticulturists, agronomists, and breeders. Under field conditions, the classification based on cultural practices has been proved the best adaptable and very useful for the growers. Vegetable crops can be classified in the following ways for the convenience of different groups of scientist and growers:

After attaining green revolution, nutritional security is of utmost importance in the current agricultural scenario. Vegetables play a key role in providing nutritional security in the country. They are important and readily available source of mineral nutrients and vitamins and play a vital role in the financial economy of the majority of small and marginal farmers. Further, these roles are becoming more transparent in the light of agriculture diversification as the vegetables have many agro-economic advantages and can fit into varying cropping systems under diversified conditions. After China, India is a leading vegetable producer but the productivity of vegetables per unit area is very low compared to other developed countries. Poor crop stand establishment is one of the factors responsible for low productivity. Yield and productivity can be improved by using advanced technology on the field preparation, optimum sowing conditions, correct nursery practices and planting methods.

Almost all the vegetable crops are propagated by seed, except a few. Crops are raised either by direct seeding in the field or by transplanting seedlings raised in nurseries. Direct seeding is the placement of seeds at desired depth into the final location where soil environment is ideal for optimum germination and crop stand establishment. On the other side, transplanting refers to removal of actively growing seedlings from one place to another with the purpose of having them continue their growth in the new location until harvest.

The vegetable crops like peas, beans, cowpea, okra, beet leaf, spinach, fenugreek, coriander, carrot, radish, turnip, beetroot, etc. are sown directly in the field, while tomato, eggplant, hot pepper, sweet pepper, onion, leek, sweet potato, cabbage, cauliflower, broccoli, Brussels sprout, kohlrabi, kale, lettuce, celery, parsley, rhubarb, squashes, etc. are first sown in the nursery beds where seedlings are raised and then transplanted in the main field. Both direct seeding and transplanting are practiced in most of the cucurbits like gourds, cucumber, melons and pumpkin.

The directly sown vegetable crops do not respond to transplanting because their embryonic roots do not produce lateral fibrous roots after uprooting unlike transplanted crops where numerous fibrous roots are generated, thus, making the plant to absorb more nutrients.

Edaphology is the study of soil properties in relation to plant higher production.

Pedology refers to study of origin of soils in their natural environment, classification and description.

pH is the negative logarithm of the concentration of H+ ions in soil solution.

Soil profile is a vertical exposure of horizon sequence.

Soil texture is not changed by cultural management.

Cation exchange capacity (CEC) is defined as sum total of exchangeable cations that a soil can absorb.

ABSTRACT

An understanding of the metabolism of heavy metals facilitates biotechnological use of these functions just recently, although heavy metals comprise the major part of the elements in the periodic table. Due to their ability to form complex compounds, some heavy metals are essential trace elements. In any case, essential or not, most heavy metals are toxic at higher concentration. Heavy metal pollution from last few decades has led to an increased environmental concern. Heavy metal like cadmium is a non-essential toxic heavy metal and is also being increased in soil during last few years posing a serious threat to environment and human health worldwide. Therefore, remediation strategies of the contaminated sites are great concerns and can be achieved by a number of different physico-chemical and biological means.

The availability of wide range of pesticides though has been responsible for increasing crop production through regulating arthropod (insect and mite) pest populations in agricultural and horticultural crop production systems but unfortunately, improper and excessive use of pesticides has resulted into a number of potential ecological problems including pest resistance, resurgence, residues in food, feed and fodder, environmental contamination, direct hazards to the users and mainly destruction of beneficial organisms including natural enemies. The most important group of natural enemies is entomophagous insects i.e. insect predators and parasites. Predatory insects are usually much larger than their prey and are generally voracious feeders that kill and eat a wide variety of insects as they grow and reproduce. Many predators are active in both their immature as well as adult stage. Insect parasites/ parasitoids are often tiny, non-stinging wasps. Parasitic wasps are free-living in the adult stage, but in the larval stage are parasitic on specific insects. The parasitic larvae eat their hosts from within, ultimately resulting in the death of the host insect. The compatibility of natural enemies with pesticides is essential as both these management strategies are important part of Integrated Pest Management programs designed to regulate arthropod pest populations and minimize plant damage.

14.1 Introduction

Indoor air pollution causes significant health problems for the two billion people worldwide who rely on biomass fuels for their cooking and heating needs. Over the last 30 years awareness of the environmental and social costs of using traditional fuels and stoves has grown. At the same time, studies of the problem have resulted in proven strategies to reduce both fuel use and harmful emissions. Unfortunately, the local stoves currently available do not always represent the best designs that modern engineering can offer. Although open fires are often used wastefully, carefully operated open fires can be fuel efficient and clean burning when tested in the lab. In many situations, cooks are not overly concerned with fuel use, and studies have shown that when fuel is plentiful three-stone fires can use an excessive amount of wood to cook a small amount of food. But in other places where fuel is scarce, open fires can be carefully controlled so that fuel efficiency rivals many first generation improved cook stoves.

Modern cook stoves are designed to clean up combustion first. Then the hot gases can be forced to contact the pot and increasing efficiency without increasing harmful emissions. Fires can be clean burning when expert cooks push the sticks of wood into the fire as they burn, metering the fuel. The open fire can be a hot fire useful when food or drink needs to be prepared quickly. The energy goes into the pot, not into the cold body of a stove. The open fire can burn wood without making a lot of smoke; hot fires burn smoke as it is released from the wood (Fig.14.1). Unfortunately however, many fires used for cooking are built emphasizing simplicity of use and are wasteful and polluting. Modern stoves score higher when tested than even the most carefully operated fire in the laboratory.

India is the largest producer of pulses in the world with 24% share in the global production. During 201011, the total production was 18.09 million tonnes from an area of 25.6 million hectare (Table 1). The important pulse crops grown in India are chickpea (48%), pigeonpea (15%), mungbean (7%), urdbean (7%), lentil (5%) and fieldpea (5%). The major pulse producing states are Madhya Pradesh, Maharashtra, Rajasthan, Uttar Pradesh, Karnataka and Andhra Pradesh, which together account for about 80% of the total production. The pulses production does not keep pace with the domestic requirement and consequently, the nation has to import 23 million tonnes and the per capita availability of pulses has declined progressively from 41.6 g in 1990 to 37 g in 2008 (Indian Council of Medical Research recommends 65 gm/day/capita). Thus, increasing production from the current level poses a serious challenge for the nation.

Even with the best of efforts, pulses production and productivity has more or less remained stagnant. Due to the low productivitylow input nature, pulses are grown as residual/alternative crops on marginal lands after taking care of food/income needs from high productivityhigh input crops like rice and wheat by most farmers. Also, they grow as rainfed crops with little or no modern yield enhancing inputs. The low priority accorded to pulse crops may be related to their relatively low status in the cropping system. As a crop of secondary importance, in many of these systems, pulse crops do not attract much of the farmer’s crop management attention. In deficient soils, the application of micronutrients has also been found to be remunerative, yet the farmers hardly use these inputs. Seeds of newly developed varieties are not available to the farmers in the required quantities. As a result the seed replacement rate is hardly about 2 to 5%. In addition to this, these crops are adversely affected by a number of biotic and abiotic stresses, which are responsible for reduced yield. Lack of onfarm storage facilities and the vulnerability of pulses to store grain pests also results in considerable losses. Stray cattle and blue bulls are responsible for a lot of damage to the pulse crops especially during offseason, thus affecting adversely the cultivation of crops like mungbean, urdbean, pigeonpea, fieldpea and lentil in Bihar, Uttar Pradesh, Madhya Pradesh, Rajasthan and Haryana also resulting in instability and low yields.
