2.1 INTRODUCTION

With increasing population, urbanization and continuous depletion of natural resources, there has to be a paradigm shift in farmer’s perception from production to productivity and to profitability. In the present scenario, the major challenges arising are shrinking land and depleting water and other related resources in agriculture. There is need for promoting farmer friendly location specific production system management technologies in a concerted manner to achieve a vertical growth in horticulture production duly ensuring quality of produce and better remuneration per unit of area with judicious use of natural resources. In this endeavour, precision farming aims to have efficient utilization of resources per unit of time and area for achieving targeted production of horticultural produce. With the revolution in information technology, now it has become possible to focus on the positioning of agricultural tools with high degree of accuracy and sophistication for maximizing returns. The combination of information technology and use of hi-tech equipments made it possible for the introduction of precision farming. It is a comprehensive system designed to optimize agriculture production through the application of crop information, advanced technology and management practices. With recent advances in geographic information systems, it has become possible to focus on site specific crop production technologies so as to harness the potential of horticulture through innovative technologies in a sustainable manner.

5.1 Elements of Landscape Gardens

5.1.1 Introduction

Elements of a garden are the basic units of any visual design which form its structure and convey visual messages. Elements are based on the art principles of landscaping. Process of landscape design includes concepts and elements of landscape designing. Generally, elements of a garden are divided into 2 types

Origin

The world ‘Communication’ comes from the Latin word ‘communis’, meaning common. This implies that when we communicate, we are trying to establish ‘Commonality’ with someone through a message. Communication, then, is a conscious attempt to establish commonality over some idea, fact, feelings and the like, with others. In essence, it is a process of getting a source and a receiver tuned together for a particular message or a series of messages.

1. Introduction

Disasters are events that occur over a period and cause widespread destruction, suffering, or distress to everything they affect (Oxford English Dictionary, n.d.). The impact of a disaster may be confined to specific areas or widespread and could last for an extended duration, often requiring assistance from external sources to address the aftermath (International Federation of Red Cross and Red Crescent Societies [IFRC], n.d.). These events can arise from naturally occurring phenomena, such as earthquakes, tornadoes, or floods, as well as man-made occurrences, including industrial accidents (e.g., accidental toxic spills or nuclear power plant events) or acts of terrorism (e.g., bombing or poisoning) (United Nations Office for Disaster Risk Reduction [UNDRR], n.d.). Disasters typically result in significant harm to infrastructure, loss of life, displacement of people, and severe economic consequences.

Introduction

Seafood demand has grown over the years due to its numerous nutritional advantages, acting as a primary contributor to global nutritional security, and the industry supports the livelihood of several million people. Persistent growth in demand for animal protein keeps the fisheries and aquaculture an important role. The average annual seafood demand growth across countries varies between 6 % and 7.5% (Kidane et al., 2021). Hence, Increased fish production, increased the per-capita fish consumption of the respective country (Garlock et al., 2022). Global average fish consumption has increased from 9.9 kg in 1961 to 20.5 kg in 2019 (FAO, 2022). The coastal countries of Iceland and Maldives are leading in per capita fish consumption with 92 kg and 85 kg respectively. While, landlocked countries such as Afghanistan, Ethiopia, and Tajikistan are the least in per capita fish consumption with less than 1 kg of fish per annum. The leading fish producers China (39 kg) and India (6.8 kg) positioned 7th and 15th place respectively in 2019 (World Economic Forum, 2022). India plays a significant role in export as like production with a global share of 5.2 % after Norway (10.4 %) and China (8.6 %). Shrimp is the primary commodity of export in India’s seafood basket with a share of 25 % of the World’s shrimp export next to Ecuador (44 %) during 2021-22. Frozen f ish is the second largest exportable item of India’s seafood export which contributed 22 % in quantity and 8.6 % in earnings next to frozen shrimp with 41 % in quantity and 67 % in export earnings. Followed by frozen cuttlefish & squid and dried items had an export share of 9 % and 5 % respectively during 2022-23 (MPEDA, 2023). Shrimp farming in India is also extending from 1.17 lakh hectares during 2010-11 to 1.67 lakh hectares during 2020-21 in India with production of 1.3 lakh tons to 8.4 lakh tons of shrimps respectively to meet the trade advantage.

10.1 Evapotranspiration (ET = Evaporation + Transpiration)

Evaporation is a diffusive process by which water from natural surfaces, such as free water surface, bare soil, from live or dead vegetation foliage (intercepted water, dewfall, guttation etc) is lost in the form of vapour to the atmosphere. It is one of the basic components of hydrologic cycle.

Likewise transpiration is a process by which water is lost in the form of vapour through plant surfaces, particularly leaves. In this process water is essentially absorbed by the plant roots due to water potential gradients and it moves upward through the stem and is ultimately lost into the atmosphere through numerous minute stomata in the plant leaves. It is basically an evaporation process. However, unlike evaporation from a water or soil surface, plant structure and stomatal behaviour operating in conjunction with the physical principles governing evaporation modify transpiration.

Thus, evapotranspiration is a combined loss of water from the soil (evaporation) and plant (transpiration) surfaces to the atmosphere through vaporization of liquid water, and is expressed in depth per unit time (for example mm/ day). Quantification of evapotranspiration is required in the context of many issues:

ABSTRACT

Indole alkaloids gramine, tyramine and tryptamine were isolated from the aerial part of Cynodon dactylon (L.) Pers. for the first time and their antimicrobial properties agains microbial pathogens were studied. Structures of the compounds were elucidated base upon the spectroscopic data such as ¹H-NMR, ¹³C- NMR and MS. The evaluations o the crude extract and the alkaloids for their efficacy in inhibiting the growth of huma pathogenic bacteria and dermatophytes were carried out in vitro. The crude extrac was effective in inhibiting the growth of all the tested microorganisms. Tryptamin and tyramine did not inhibit microbial growth when tested individually, but in combination the growth inhibition of Klebsiella pneumoniae was prominent. Gramin was the most effective one in inhibiting the growth of all the tested microbial pathogens

Mushrooming population, subsiding agricultural resources; land and water, people’s concern towards quality of vegetable s/food and changing climate throws several challenges for vegetable production. Conventional management and crop improvement strategies alone can no longer sustain the nation’s as well as global demand. So there is an urgent need to adopt modern biotechnological methods which are multidisciplinary where a large number of tools and elements of conventional breeding technique, genetic engineering, molecular biology, molecular genetics, bioinformatics and biochemistry are utilized and integrated. Biotechnological tools provide three major aspects of genetic improvement viz, application of tissue culture, molecular breeding or marker assisted breeding and genetic engineering.

It looks to saddle the inventive control of this sort of examination for advancement and revelation. The agent's address is, do considering these components include important measurements to investigate? Do they take research in unused bearings? To reply to these questions, Gendered Developments creates down-to-earth strategies of sex, sexual orientation, and intersectional examination for researchers and gives case ponders as concrete outlines of how this sort of investigation leads to revelation and advancement.

Introduction 
The ancient educational systems of renowned universities not only advanced knowledge across various disciplines but also significantly influenced the economic and social structures of their times. Education serves as a gateway to liberation and development, providing individuals with a wealth of opportunities. Conversely, a lack of education limits one’s ability to pursue personal and professional aspirations. In the educational environment, the initial relationship a child forms is with their teacher. When teachers understand their students, it fosters strong relationships, effective communication, innovative learning approaches, and capacity building. Since students spend a significant portion of their day at school, mutual respect and tolerance between students and teachers are essential for a productive learning environment. Over recent years, the education system has evolved rapidly, incorporating new teaching methods and strategies as alternatives to traditional models. However, traditional views often assert that “learners must submit themselves to teachers” (Menges, 1977, p.5), implying that teacher authority is crucial for student learning. Hurt, Scott, and McCroskey (1978) argued that a certain degree of teacher authority is always present in the classroom, and its usage tends to reinforce the need for more control. This perspective highlighted the critical role of the classroom as a space for students’ educational success (Anderson & Burns, 1989; Borich, 1988; Fraser & Walberg, 1991; Walberg, 1968). Positive teacher-student relationships are essential for fostering a sense of belonging and encouraged cooperative participation in classroom activities (Hughes & Chen, 2011, p.278). Such relationships not only engage students in learning but also enhance their holistic development, social skills, and confidence. As we know, historical institutions such as Takshila and Nalanda exemplify ancient centers of learning that combined theoretical and practical education. Takshila, located in present-day Pakistan, was one of the earliest centers of higher learning in ancient India, offering diverse subjects including medicine, engineering, astrology, and statecraft. Nalanda, in present-day Bihar, was a prominent center for Buddhist learning, focusing on philosophy, logic, and practical subjects like agriculture and technology. These ancient educational hubs were pivotal in advancing knowledge and contributing to the economic and intellectual development of their societies. The principles of vocational education and holistic development emphasized in the National Education Policy (NEP) 2020 align with these historical practices (Makam, 2022). Effective implementation of NEP 2020 requires a fresh approach through comprehensive teacher training and rigorous evaluation of expectations and feedback focused on Sustainable Development Goal 4 (SDG4) is focused upon to create a relation with ancient practices.

Among the various modern surgical methods, laparoscopy is now held as one of the most potent and promising aids for both diagnostic (laparoscopy) and therapeutic (laparoscopic surgery) use. Laparoscopy is an endoscopic procedure that bridges the gap between clinical evaluation and surgical exploration. The laparoscopic surgical techniques in both and human and veterinary medicine have grown tremendously. Laparoscopy requires a minor surgical intervention and it provides the only available practical means of making repeated direct observation of abdominal viscera. The advantage of surgical laparoscopy over the conventional open surgical laparotomy include faster patient recovery because of smaller surgical sites, decreased hospitalization, improved cosmetic, improved visualization of abdominal organs, lower postoperative morbidity with lower infection rates, and less postoperative pain and stress. Surgeons are commonly looking for more progressive and stressful surgical methods of sterilization in dogs, particularly in canine birth control programs in urban industrial areas. Demographically dense urban and industrial areas require effective animal birth control programs that can overcome the problems of hospitalization, postoperative complications and reduction in the overall cost of operation. In a large scale animal birth control program, the conventional methods of sterilization require a long period between capture of dogs and their release, due to the time taken for the surgical wounds to heal. In this aspect, keyhole surgery (laparoscopic surgery) can revolutionize the entire program, as it needs only a very small surgical wound, which usually needs no postoperative care or regular dressings.

Agroforestry systems essentially involve a perennial component and provide cover to the soil through litter fall and tree canopy, which contribute to the conservation of soil and water resources in arid and semi-arid areas. Moreover, arid and semi-arid areas are exposed to extensive soil erosion by wind and water, respectively.  Planting of trees on erosion control structures as windbreaks, boundary plantations and tree-based systems are some of the potential ways for conserving natural resources (Singh, 2003).  Agroforestry and soil conservation have major role to play in the context of global climate change likely to occur from extremes of weather events and erratic rainfall behaviour.
 
    •    Provide  permanent vegetative cover to the soil or land surface and thus substantially control erosion caused by both runoff and wind.

    •    Improve soil quality through increased soil organic matter addition from litter fall and root turnover; and  improved  environment for soil microbe and earthworm activity. 

Introduction

The organic matter added to soil externally as FYM, crop residues, leaf fall, root deposition etc. has been a part and parcel of Indian agriculture. The total carbon added to soil is subject to microbial decay and slowly the major portion of it finds way back to the atmosphere. There is every possibility that atmospheric CO₂ concentration will increase in near future; that will further lead to increased attention of scientific community to make soil a possible sink for atmospheric CO2. when the carbon sequestration is thought with the perspective of reducing carbon dioxide emission for healthy atmosphere at one hand and improving soil health on the other, there is utmost need to opt for technologies that can fulfill both these objectives. There is growing interest in the use of charcoal or ‘biochar’ to sequester carbon in soil and improve soil fertility (Lehmann and Joseph, 2009). There are many types of soil additives and fertilizers used to improve the structure and functions of soil. Biochar has re-emerged as an issue in the last ten years as everyone is looking for sustainable ways to improve soils and decrease use of chemical fertilizers. 

1. Introduction

Osmotic dehydration is a useful treatment of dehydration compared to the other dehydration processes, as other dehydration processes bring adverse and irreversible changes in physical and nutritional status of food material. Recently in many studies it was found out that since plant membranes are semi-permeable in nature, not only moisture but transfer of solute from osmotic solution to the food material also takes place. Another kind of transfer which was also noticed is the leaching of micronutrients from the cells of food to the osmotic solution, but the amount being very low, this transfer can be neglected. (Mayor et al., 2006). The mass transfer kinetics was studied for different food materials (Hawkes and Flink, 1978). Effect of different variables such as pressure and temperature were also studied (Rastogi and Niranjan, 1998). The effective diffusivities for both water loss and solute gain can be calculated by using various methods which gives the rate of diffusion of solute and moisture for the food material. The finding of solute gain and leaching of micronutrients pointed the requirement of maintaining the osmotic dehydration process, which could be done by maintaining the process variables of osmotic dehydration. Impact of various process variables on osmotic dehydration and their best levels at which maximum water loss and minimum solute gain could be obtained had to be calculated out. For this purpose, optimization of process variables through response surface methodology (RSM) could be best utilized (Uddin et al. , 2004). RSM is a statistical tool which gives the random combinations of input variables to give the best output result as required. Various works have been done on optimization of process conditions of osmotic dehydration taking different samples of foods. In this study, bamboo shoot species (Bambusa balcooa) was taken as sample for osmotic dehydration to optimize the process variables for osmotic dehydration of bamboo shoots using salt as osmotic agent followed by calculation of effective diffusivity of water and solute during osmotic dehydration of bamboo shoot.

There has been an increasing demand for horticultural crops more particularly fruit .With this, the demand for good quality planting materials has gone up and hence the nursery business has developed rapidly in the recent years in our country. Plant propagation aims at the reproduction of selected individuals or group of individuals, in this the basic principal of life impose certain requirements which must be met with in practices for successful propagation. Plants material of various fruit crops have not only to be raised efficiently and scientifically, for which skilled knowledge in raising and management of nurseries is needed, but also these have to be transported quickly from nurseries to place where these plants materials will be grown.

Availability of quality planting material is one of the most importanant requirement for increasing the production and productivity of any fruit crops. It becomes one of the great challenges for horticulturists to get the disease free quality planting materials of fruit crops from an efficient and reliable nursery.

1. Introduction

Information is necessary for the economic, social, and cultural development of individuals and communities, and libraries play a significant role in providing access to information, which is essential for this growth. These institutions function as centers of knowledge, offering a wide range of resources to their users, including books, journals, databases, and multimedia materials, in order to meet the varied requirements of their users.

In this day and age, the function of libraries has evolved beyond the confines of physical locations to encompass activities such as online platforms and digital collections. Because of the large amount of information that is accessible on the internet, people rely on libraries to help them navigate through this sea of data and locate sources that are credible and reliable.

Closed Nucleus Breeding Scheme (CNBS)
In the CNBS the germplasm flows in only one direction. That is from the nucleus to the cooperating herds or flocks. In the traditional pyramid there is only one way of flow of genes with in the pyramid, downwards from top to bottom. This means that the only some of cumulative genetic progress in commercial production is improvement that occurs at the top of the pyramid. If the nucleus tier makes no genetic improvement then no improvement will be noticed in the root of the tiers. However even if the nucleus tier thus make improvement progress is not seen immediately at lower levels in the pyramid. It takes time for the genetic progress in one tier to be transmitted to the next tier. The resultant difference in performance between any two adjacent tiers is called IMPROVEMENT LAG.
It is usually expressed in terms of no. of years of genetic improvement that are represented by the difference in performance between adjacent tiers. There are two factors that affect the size of the improvement. Age structure in the lower tiers. Source and merit of dams used in the lower tiers, e.g. Lag can be reduced by keeping the sires and dams in lower tiers for shorter periods of time before replacing them with younger stock. Lag can be reduced by transferring females downwards tiers. Even greater reduction result if some nucleus parent can be transferred directly to commercial tier. Only downward flow of genes from nucleus to lower tiers. No gene flow into nucleus tier, e.g. Most traditional breed of livestock modern pig and poultry breeding programme have CNBS structure.

Introduction
Education and Its Evolution
Education is a process of learning, which involves both formal and informal modes of learning, which transforms the behaviour, skills, knowledge attitudes, and beliefs of the learner. For this reason, it is more deliberate than other education activities since it is a deliberate effort to create learning in a bid to achieve set goals and objectives. Ordinarily, education is characterized by a systematic learning system that is complemented by curricula and instructional materials in different disciplines. This includes talking and explaining, discussing and questioning, performing and observing so as to reach individual students. Communication is also considered as necessary as education is a process of interconnecting people, exchanging information, and learning how to deal with society members. It also develops critical skills such as analysis and developing insights, due to its capacity to offer information to be analyzed, find solutions and then make sound decisions. Education implies character building and it shapes people into responsible members of society. Education also fosters a construct of perpetuity learning which in this case is strengths toward self and career. There is the principle of non-selectiveness as one of the basic principles of education, as education must be provided to all so that all students should be given an equal opportunity. Learners’ understanding and progress can be measured therefore, assessment and evaluation were part of the program to ensure that teaching strategies can be improved. In addition, it has a 96 | Sustainable Development Goals, Health & Education sociocultural function of passing on a culture from one generation to another, and thus preserving social and cultural development and growth. In its strictest sense education is learning as it is getting acquainted with information as well as has the added dimension of moulding positive character in the learners so that they and society can be the better for it. From antiquity to the present, education has undergone tremendous change, having a huge impact on the advancement of society. When education was first developed in ancient communities, it took the form of apprenticeships, oral traditions, and storytelling to impart cultural values, religious convictions, and useful survival skills. For the elite, it was frequently reserved, preventing access for the general public and preserving social hierarchies. A teacher-centered approach limited student interaction and critical thinking, and the curriculum prioritized memorization and rote learning with a focus on mythology and societal responsibilities. In comparison, the goal of contemporary education is to develop students’ ability to think critically, be creative, and solve problems in a formal, structured manner. Regardless of one’s background, access to it is considered a fundamental right that fosters inclusivity and social fairness. The curriculum’s diversity promotes inquiry and discovery by including technology, the arts, and the sciences. A variety of student-centered, modern teaching techniques are used to improve critical thinking and participation. Education is now a key factor in social and economic development as a result of this change, encouraging creativity and producing knowledgeable citizens who take an active role in solving global issues. After all, if education in the past served to uphold hierarchical institutions, education today aims to dismantle obstacles and promote equality in society.

The final chapter examines the commercial, institutional and policy dimensions of the Indian cut flower industry. It discusses domestic and international markets, export opportunities, grading, packaging, cold-chain requirements and India's competitive position. Institutional support from ICAR, APEDA, National Horticulture Board, MIDH, financial institutions and Centres of Excellence is explained. The chapter also covers Agri Export Zones, Export Oriented Units and crop insurance mechanisms relevant to commercial floriculture. Current challenges include freight costs, cold-chain limitations, quality standards and international competition, while opportunities arise from protected cultivation, precision farming, automation, AI, IoT, exports and premium flower markets.

Poultry has been extensively used for various biological experiments and its contributions to science are impressive. Among poultry species, chickens have made fundamental contributions to our current understanding of many immunological processes and it ranks high in the biological world. It still serves as an animal model to investigate immunogenetic aspects of disease resistance and tumor regression. Among the major contribution from poultry, the first evidence for viral induced tumor came from chicken (Rous, 1911; Nobel prize, 1966), reverse transcriptase enzyme was isolated from Avian Leukosis virus (Tamin and Baltimore, 1963; Nobel Prize, 1975), oncogenes in virus are from host cells (Bishop & Harold Varmus; Nobel Prize, 1989) and major two arms of immune response i.e. the T and B cells were first discovered in chicken.
