INTRODUCTION

Natural resources are the untamed natural essence of the environment which contain a significant amount of material as well as aesthetic values. Natural resources are broadly categorized into renewable, flow and non-renewable sources. While renewable natural resources primarily involve living sources such as forests, crops fish, reindeer, coffee, etc. and non-living sources like water and soil. Natural resource management refers to the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations. Natural resource management is congruent with the concept of sustainable development. It is a scientific principle that forms a basis for sustainable global land management and environmental governance to conserve and preserve natural resources (Wikipedia, the free encyclopedia, 2009). Though forest, water, agriculture land and crops, minerals, livestocks and many more constitute natural resources in India but forest represents the second-largest land use in India after agriculture, covering about 641,130 square kilometers, or 22 percent of the total land base (FAO 2005). Forestry is the second largest land use after agriculture and accounts for about 1.5 % of the nation’s GDP (World Bank, 2006) in India. On one hand, forests support the livelihood of the poor, especially the tribals, and on the other hand, it is remarkable to see that the poorest people of our country live in the rich forest and natural resource base (Narain, 2008).

Introduction
Antimicrobial resistance (AMR) has emerged as one of the most alarming public health challenges of the 21st century, threatening the effectiveness of life-saving drugs and the future of modern medicine. This crisis is not limited to healthcare settings; it spans communities, agriculture, and the environment, impacting every facet of society. India, with its large population, high burden of infectious diseases, unregulated access to antibiotics, and considerable pharmaceutical manufacturing industry, stands at the forefront of the global struggle against AMR. The rise of resistant microbes stems from a complex interplay of factors: overuse and misuse of antibiotics in humans and animals, poor infection prevention practices, lack of sanitation, and environmental contamination from antibiotic waste. As a result, common infections are becoming harder to treat, surgical procedures riskier, and healthcare costs are escalating, all leading to increased morbidity and mortality. Tackling AMR requires robust intersectoral collaboration—no single stakeholder can succeed alone. Non-governmental organizations (NGOs), industries, and Corporate Social Responsibility (CSR) initiatives form a critical triad in India’s fight against AMR. NGOs drive grassroots education, advocacy, surveillance, and policy change, often bridging gaps where governmental capacity is limited. The pharmaceutical and healthcare industries, responsible for antibiotic manufacturing, distribution, stewardship, and infection control, play a pivotal role in curbing environmental emissions, supporting responsible use, and promoting the discovery of new treatments. Meanwhile, CSR channels the resources and expertise of corporations towards sustainable, communityfacing projects that promote awareness, improve hygiene, foster stewardship, and drive systemic change.

3.1 Introduction

Internet of Things (IoT) allows computational devices and sensory support to connect with each other and access services on the Internet. The IoT idea was introduced to connect devices through the Internet and facilitate access to information for users. The potential application of IoT includes agriculture. The aim of this chapter is to explain the role of NodeMCU in the agriculture field. NodeMCU is IoT module which can be used to present the IoT concept as a basis for monitoring and control. The systems used in farm production processes. NodeMCU play a key role, with a focus on their realization by available microcontroller platforms and appropriate sensors. IoT based system provides opportunity to users to monitor and control the process remotely.

Water is a critical input for agricultural production and plays an important role in food security. Irrigated agriculture represents 20% of the total cultivated land and contributes 40% of the total food produced worldwide. Irrigated agriculture is, on average, at least twice as productive per unit of land as rainfed agriculture, thereby allowing for more production intensification and crop diversification. India has 18% of world’s population, having 4% of the world’s fresh water, out of which 80% is used in agriculture. India receives an average of 4000 billion cubic meters of precipitation every year. However, only 48% of it is used in India’s surface and groundwater bodies. In India, more than 60% population is still dependent directly or indirectly on agriculture. Most of the available water (more than 90%) is used in agriculture. From 1951 to 1997, gross irrigated areas expanded fourfold from 23 million ha to over 90 million ha, and irrigation continues to be the largest water user. The water availability in India is going to be worse as the agriculture-important states like Punjab, Haryana, Tamil Nadu, and Rajasthan are facing a steady fall in underground water table, and per capita availability of water fall from 3450 cubic meter (1951) to 1250 cubic meter (1999).

Introduction

In most developing nations, the primary method of managing insect pests on various crops is by synthetic insecticides. One of the fastest and most efficient ways to reduce insect populations is by chemical control where a farmer quickly achieves extraordinary results.

However, overusing pesticides indiscriminately and without proper research for longer periods of time led to a number of issues, including the risk of environmental contamination, loss of biodiversity, development of insecticide resistant pest populations, resurgence, outbreaks of secondary pests, increase in chemical inputs, toxicological hazards due to accumulation of pesticide residues in the food chain, etc.

Nutrients play a fundamental role in ensuring the health, productivity, reproduction, immunity, and overall welfare of animals. The balance and availability of macronutrients (carbohydrates, proteins and fats), micronutrients (vitamins and minerals) and water are crucial for optimal physiological and metabolic processes. This chapter explores the role of nutrients in different aspects of animal health and well-being.
Macronutrients
Carbohydrates
Carbohydrates are the primary energy source for most animals, playing a critical role in sustaining metabolic processes, maintaining body temperature, and supporting physical activity. In ruminants, carbohydrates are fermented in the rumen to produce volatile fatty acids (VFAs) such as acetate, propionate and butyrate, which serve as energy substrates.
Health: Adequate carbohydrate intake prevents energy deficits, which can lead to ketosis, fatty liver, or hypoglycemia, particularly in lactating animals. Production: Energy from carbohydrates drives milk production in dairy animals and growth in meat-producing species.
Reproduction: Insufficient carbohydrate availability can delay puberty, impair estrus cycles, and reduce fertility. Immunity: Energy deficits weaken immune responses, increasing susceptibility to infections.
Welfare: Optimal carbohydrate nutrition minimizes stress and supports natural behaviours like grazing or rumination.

There are number of internal and external factors that affect the production performance of animals, among which parasites and parasitism are major of concern constraints to animal’s productivity especially in tropical countries. Feed intake and nutrient requirements have been recognized for long time as an important parameter for determining the efficiency of animal production. Most of the parasitic infection in domestic animals is caused by gastrointestinal nematode, which may result in depression in appetite, impairment in GI functions, alteration in protein, energy and mineral metabolism and changes in water balance. Nutrition can affect the ability of the host to cope with the consequences of parasitism and to contain and eventually to overcome parasitism. Since it is proposed that the host gives priority to the reversal of the pathophysiological consequences of parasitism over other body functions, it is to be expected that improved nutrition will always lead to improved resilience. On the other hand, it is proposed that the function of growth, pregnancy and lactation are prioritized over the expression of immunity. Improved nutrition may affect the degree of expression of immunity during these phases and can thus influence the resilience and resistance of host to parasite infection.

Abstract
Fish populations are essential for global food security, marine biodiversity, and the health of ocean ecosystems. However, threats such as climate change, overfishing, and habitat degradation jeopardize their sustainability. Understanding fish population dynamics is vital for effective fisheries management and conservation. Insights into environmental factors affecting fish distribution, migration, and spawning are derived from oceanographic data collected using advanced technologies such as satellites, Autonomous Underwater Vehicles (AUVs), and remote sensing. By integrating these data with fish population models, predictive capabilities are enhanced, enabling proactive management and conservation efforts. Despite technological advances, data gaps and the complexity of biological and environmental interactions pose challenges. Integrating big data and artificial intelligence offers promising opportunities to improve predictive accuracy, optimize real-time fishery management, and tackle sustainability challenges effectively. This article discusses the role of oceanographic data in predicting fish population dynamics, the technologies involved, and the challenges facing current models.

1. Introduction

Universal development through Education for all had been a prominent feature earlier during Millennium Development Goals and recently it has gained a fresh momentum when United Nations General Assembly set 17 inspirational Sustainable development Goals. Quality Education is the focus of SDG 4, “Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all” (Sustainable Development Goals, 2023). Role of education in achieving these sustainable development goals in developing countries is well recognized by OECD. OECD in its report on ‘Education at a Glance 2013’ states that “Educational attainment is frequently used as a measure of human capital and the level of an Individual’s skills. The level of educational attainment is the percentage of population that has reached a certain level of education. Higher levels of educational attainment are strongly associated with higher employment rates” (OECD, 2013). Furthermore, OECD in its report published in 2017 explains that “Making SDG 4 a reality will transform lives around the globe. Education is so central to the achievement of a sustainable, prosperous, and equitable planet that failure to achieve this particular SDG puts at risk the achievement of the 17 SDGs as a Whole” (OECD, 2017).

As per United States Department of Agriculture (USDA), organic farming is defined as a system which avoids or largely excludes the use of synthetic inputs (such as fertilizers, pesticides, hormones, feed additives etc.) to a maximum extent and feasible rely upon crop rotations, crop residues, animal manure, off farm organic waste, mineral grade rock additives and biological system of nutrient mobilization and plant protection. FAO suggested that organic agriculture is a unique production management system which promotes and entrance agro-ecosystem health, including biodiversity, biological cycles and soil biological activity and this is accomplished by using on-farm agronomic, biological and mechanical methods is exclusion of all synthetic off-farm inputs.

The increasing awareness of the deleterious effects of indiscriminate use of chemical fertilizers and pesticides in agriculture has led to the adoption of organic farming as an alternative method for conventional farming world-wide. It is gaining gradual momentum across the world and the growing awareness of organic food which is emerging as an attractive source of rural income generation especially in integrated farming systems.

In north west India where rice-wheat, cotton-wheat and pearl millet-wheat cropping systems are most prevalent. But now, these cropping systems are not proving farmers’ friendly due to higher water requirement, declining yield, susceptibility to insects and pests and adverse effect on soil health. Moreover, in the new millennium with the growing demand of agricultural commodities in national as well as international market due to ever increasing population and globalization, Indian farmers are forced to produce higher quantum of quality agricultural commodities at low cost from shrinking land and natural resources.

Mungbean - wheat cropping system requires less water and hence, can be grown in areas where water availability is limited in addition to beneficial effect of mungbean to supply N to the succeeding wheat crop which are favorable for organic farming. Wheat (desi) also known as tall wheat requires less water and is very responsive to low doses of nutrients. The dwarf wheat grown by farmers with the application of chemicals in the form of fertilizers, weedicides, insecticides and pesticides is not preferred by people and therefore, the demand of organic wheat is rising fast in national and international market. This cropping system can be taken successfully in farming systems for higher monetary returns.

There is need to shift a portion of cultivable land with organic farming as an alternate practice technique. Organic farming gives emphasis on sustainability, environmental safety and low cost production techniques over chemical farming. Keeping the issues of 21^st century agriculture in view following aspects also shows importance of organic farming: Reduce the toxic load; keep chemicals out of the air, water, soil and our bodies; reduce if not eliminate off farm pollution; protect future generations; build healthy soil; taste better and truer flavor; assist farmers of all sizes; promote biodiversity; celebrate the culture of agriculture etc.

Introduction

The ill effects of chemicals used in agriculture have changed the mindset of consumers in different countries, who are now buying organic products with a high premium for health. Policymakers are also promoting organic agriculture for the restoration of soil health and the generation of the rural economy, apart from making efforts to create a better environment. The world principles of organic farming have emerged in the form of biological farming, ecological farming, permaculture, biodynamic agriculture, green farming, bio-intensive farming, zero-input agriculture, etc..

Organic agriculture is one of the broad spectrums of production methods that are supportive of the environment. Organic production systems are based on specific standards precisely formulated for food production and aim at achieving agroecosystems that are socially and ecologically sustainable. Organic farming practices help in increasing carbon sequestration, soil and water conservation, and minimizing risk in agriculture. The important aspects of organic farming with respect to water conservation are mentioned in this chapter.

Organic liquid formulations (OLFs) are agricultural inputs derived from natural sources, designed for use in organic farming. These formulations, consisting of liquid solutions or suspensions containing organic compounds, nutrients, and beneficial microorganisms, play a crucial role in enhancing soil fertility, plant nutrition, and pest management, while promoting environmental sustainability and ecosystem health. Despite their eco friendly nature, OLFs demand careful consideration for their environmental impact and safety. They biodegrade readily, reducing long-term persistence and are less harmful to non-target organisms. While OLFs offer numerous benefits, they also face limitations in potency and effectiveness compared to synthetic pesticides, often requiring more frequent applications and leading to increased labor costs. Their impact can vary with pest species and environmental conditions, and they generally provide gradual rather than immediate pest control. Availability and accessibility can be limited, posing challenges for some farmers. This chapter explores the role of OLFs in achieving success in organic farming, highlighting their benefits and limitations, and emphasizing the importance of Integrated Pest Management strategies and careful consideration of various factors to optimize their use in promoting sustainable agriculture.

Soil is the product of various soil forming factors acting on the parent material over a period of time. The parent material is usually devoid of organic matter and consists of variable quantities of sand, silt, clay and carbonates. High temperatures and adequate moisture promote mineral transformations, but these effects are magnified by living organisms and the organic substances they produce. The biosphere and the organic substances they produce are directly or indirectly responsible for the following:

1. Decay of organic matter by microbes leads to the formation of CO₂ which is quantitatively the most important “aggressive” weathering agent because of its tendency to form carbonic acid with water [CO₂ + H₂O → H₂CO₃].

As the population of the world rises, there is an increase in the demand for food production. Agricultural packaging helps farmers and makers to deliver food in the handiest approach with no loss. It eliminates unnecessary wastage of food during post-harvest treatment procedures, production process, storage, and transportation. It ensures short and long-term stability between the farmers and the consumers. Pesticides are completely toxic and reactive and thus need correct packaging. In agricultural packaging of pesticides, pouches with excellent quality standards are used that improve sealing and handling issues and avoid any malfunctioning. Ventilation is very important in agricultural packaging that permits the warmth and to cool quickly. Loss of water of the products should be minimized to let them stay fresh for a longer time.

In this century the usage of plastics had become very common. However, it is important to know as to what kinds of plastics are used for food handling and storage and the health hazards caused by using it. It has been observed that plastic packaging plays a significant role for the enhanced shelf life and in the ease of storage and cooking for many foods. Some kinds of plastic materials which are widely used for handling and storage of food and water include polyethylene terephthalate (PET). It is used in soft drinks, water, sport drinks, ketchups, salad dressing bottles, peanut butter, pickle, jelly and jam jars. This plastic is strong, heat resistant, resistant to gases and acidic foods. It can be transparent or opaque. It does not leach any chemicals that are suspected of causing cancer or disrupting hormones and can also be recycled.

Usage of High density polyethylene (HDPE) has been found to be common in milk, water, juice bottles, yogurt, margarine tubs, grocery, trash and retail bags. High-density polyethylene is stiff and strong but is not heat stable (it melts at a low temperature). It does not leach any chemicals that have a role in causing cancer or disrupting the hormones. HDPE can be recycled. Low-density polyethylene (LDPE) is used into making films of various types, some bread and frozen food bags and also in the making of squeezable bottles. Low-density polyethylene is relatively transparent. Many of the films are not heat stable either and may melt the food in case it is touching it. However, polypropylene (PP) is more heat resistant, harder, denser and more transparent than polyethylene and is therefore used for heat-resistant microwavable packaging and sauce or salad dressing bottles. Polycarbonate is clear and heat resistant. It is also durable and often used to make refillable water bottles and sterilisable baby bottles, microwave ovenware, eating utensils, plastic coating for metal cans. Tiny amounts of bisphenol A are formed when polycarbonate bottles are washed with harsh detergents or bleach (sodium hypochlorite). At high levels of exposure, bisphenol A is potentially hazardous as it mimics the female hormone estrogen. In addition, polystyrene (PS) and polyvinyl chloride (PVC) are also used during food material transportation and handling in supermarkets. Modern food safe plastic bags are plasticizer-free which do not leach harmful chemicals into the food during cooking.

Probiotics are measured in colony forming units (cfu). CFUs are generally measured in the millions or billions per serving. Probiotics are most commonly beneficial bacteria, but can also be friendly fungal or other organisms, that are typically freeze dried to stabilize them in an inert state during storage and production. Then their continued stability and viability, as measured by CFU counts when cultured, is dependent on limiting their exposure to stimulating environmental conditions such as temperature and moisture. Besides refrigeration, this protection can be done by packaging in glass or by adding freshness packets that helps to absorb and reduce moisture in the package.

Introduction

The world of living organisms essentially consists of the kingdoms of plants and animals. Myriads of organisms representing these two, interact among them, ranging from symbiosis and mutualism to competition and predator-prey interactions. The last mentioned process is one the important components of ecological dynamics, that determine the balance of nature or equilibrium among the biota. To this category belong the predators, parasites (parasitoids), pathogens, and so on, all of which live at the cost of another organism, without affording any benefit to the ‘victim’, hence the victim is termed the ‘prey’. In an agroecosystem, when an organism, explodes into an unusually high number, devouring cultivated plants it often becomes a ‘pest’ from a man’s point of view. Sometimes the pest can be a human nuisance too. It is here, that the role of predators and parasitoids become relevant as biological agents against the pests.
 
A lion, which preys on herb-feeding antelopes, is also a predator. But, its roles become restricted to maintaining the balance of the antelope population. Left undeterred, antelopes can explode to levels that can threaten grasslands. Here lions play a very crucial role in maintaining (through hunting antelopes) the equilibrium of the grasslands, just sufficient for these plants to surge with every rain. Otherwise, the grasslands potentially may get denuded by the antelopes, or conversely it may override other ecosystems. This is part of the ‘food web’ and is found in every ecosystems; desert, aquatic, mountains, forests, agro-ecosystems, etc.

Abstract

Phosphorus is the second important key element after nitrogen as a mineral nutrient in terms of quantitative plant requirement. Although abundant in soils, in both organic and inorganic forms, its availability is restricted as it occurs mostly in insoluble forms. The dynamics of phosphorus in soil is closely related to the dynamics of the biological cycle in which microorganisms play a central role. They also participate in the cycles of the most important macro and microelements such as phosphorus besides their major role in the decomposition of plant residues, creation of humus and maintenance of stable soil structure. Microorganisms affect the amount of phosphorus accessible to plants by means of mineralization of organic phosphorus compounds, immobilization of available phosphorus and solubilization of non-soluble phosphorus minerals such as tricalcium phosphate. Mineralization is catalyzed by microbiological enzymes phosphatases secreted by a diverse group of bacteria, fungi and other groups of microorganisms. Organic phosphorus mineralization in soil depends on several soil and environmental factors such as temperature, pH, soil moisture, degree of aeration. In this chapter the major emphasis is given on the transformation of P through microbiologically involving different enzymes and also the microorganisms involved in the process. Emphasis is also given on the factors that have profound influence on the microbial transformation of P in soil and ultimately making it available for plant uptake. This chapter also focuses on the mechanism of P solubilization, role of various phosphatases, impact of various factors on P solubilization and potential for application of this knowledge in managing a sustainable environmental system.

Flowers are the reproductive structures of Angiosperms. The apical shoot meristem of the vegetative plant continues to produce new leaves and vegetative buds, which may develop into branches, but after sometime, the meristem, instead of producing leaves and branches, becomes transformed into specialized reproductive structures called flowers. The transformation of vegetative shoot apex into re-productive structure is called flowering. The process of flowering is controlled by two main important environmental factors, i.e., (i) the duration of light received by the plant called photoperiod and (ii) the low temperature treatment given to the seed or the plant referred to as vernalization (Figure 6.1).
