1. Introduction

Libraries play a crucial role as community centers that promote education, culture, and individual growth at a time when information is the currency of advancement. Rural libraries, however, confront unique difficulties that set them apart from their urban counterparts. Rural libraries often struggle with limited funding, being geographically isolated, and having difficulty obtaining technology infrastructure. Yet, in order to guarantee that rural libraries can provide the same caliber of service as their counterparts in larger cities, pricing and accessibility become vital factors. And in light of all of that, they continue to be vital community hubs that contribute significantly to education, cultural enrichment, and lifelong learning.

Open source solutions hold a lot of promise for addressing these problems.Open source software solutions are more affordable and flexible than proprietary software systems, allowing them to be tailored to the specific needs of any rural library. Among other reasons, the library staff finds it easier to catalog documents when they use these kinds of systems. Because these systems use simpler circulation techniques, they assist them with saving expenses while guaranteeing higher user involvement.

1. Introduction

Libraries and information services have traditionally been seen as quiet sanctuaries of knowledge and learning. However, in today’s rapidly evolving digital age, libraries must actively market their services to ensure they remain relevant and accessible to diverse user groups. Marketing these services involves not only promoting the library’s offerings but also effectively communicating its value to the community. Marketing in case of libraries is necessary to offer benefits to users’ want, reduce barriers to use and access, persuade and inform the users, and carefully plan to satisfy users’ needs effectively. “Marketing is so basic that it cannot be considered a separate function within the library. Marketing is a central dimension of the entire library. It is the entirety of the library’s operations and services seen from a point of view of its final result, that is, from the customer’s point of view” (Gupta and Savard, 2010). Marketing library and information service is an established sub-set of management practices which identifies customer wants and needs and meets those needs within the resources of the organization (Gupta, Koontz & Massisimo, 2013).

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.

1. Introduction

No doubt Village library is a part of public library. Village library plays an important role for creation knowledge in different field. As we know that maximum people in the village area not aware about their right, even they not know reading and writing. so the rate of literacy is poor. Therefore it can be mentioned that the illiteracy is the main barrier for their development and it will harm their day to day life. Many people in the villages is involve themselves in farming. Agriculture is the main of earning sources. Villagers do not have adequate knowledge in farming and fertilizer that they used for better result even they not know the bad affect of fertilizer that they used. Their life style is not hygienic because of illiteracy.

1. Introduction

In the era of digital technology, libraries have expanded their role beyond their initial role as storage facilities for physical material. Libraries have become essential in providing access to electronic resources and promoting lifelong learning due to the emergence of e-learning. E-learning refers to the use of digital technology to access learning materials outside of a traditional classroom setting. E-learning is emerging as a powerful influence in higher education, with a presence on nearly every campus and a growing number of college and university courses. The environment is characterized by growth and dynamism, where fluidity and change are the social, institutional, and technological norms (Mishra & Gupta 2019).

Technology has revolutionized education, turning it into e-learning and internet based learning. This evolution provides individuals with the opportunity to have more freedom, convenience, and the ability to work virtually. Libraries must modify their resources and services to meet the emergence of e-learners. Academic libraries have now established connections with web-based services and e-resources, which are moving the profession forward at a rate never before seen. (Ramkumar & Kannan, 2023)

1. Introduction

There is a real climate change, and human activity is its primary driver. Notably, worldwide average temperatures have been rising consistently since the beginning of the Industrial Revolution, posing a danger to life as we know it from climate change. For example, 2019 had record sea levels, melting ice, and unusually high global temperatures as a result of increased human activity. Regrettably, in spite of the fact that climate change is causing the environment to deteriorate more and more, insufficient worldwide pledges have been made to mitigate its effects. Thus, the necessity for green libraries became apparent. In India, green libraries are becoming more and more important as the country works toward achieving the Goals for Sustainable Development (SDGs). These libraries promote a comprehensive approach to environmentally friendly growth by serving as examples of social responsibility, environmental care, and economic success. Green libraries use eco-friendly construction materials, sustainable waste management practices, and renewable energy sources like solar power in their design. They clearly support climate resilience and drastically cut carbon footprints, which is in line with SDG 13 (Climate Action). Additionally, by fostering environmental literacy, lifelong learning for people of all ages, and inclusive and equal access to knowledge and educational resources, green libraries in India actively support SDG 4 (Quality Education). Additionally, by acting as green public spaces that improve urban livability and provide a haven from the bustle of city life while encouraging social cohesion and community participation, these institutions serve SDG 11 (Sustainable Cities and Communities).

1. Introduction

Education is undergoing a digital transformation. The incorporation of digital technologies into the educational scene over the last two decades has radically changed the way we teach and learn. This transition has started a revolution with far-reaching repercussions, both positive and negative, for students, educators, and institutions alike.

The growing adoption of digital technologies in educational settings has created a world of possibilities. Online platforms, learning management systems, educational apps, virtual reality, and augmented reality are just a handful of the innovations that have transformed the educational experience. This comprehensive investigation tries to investigate the intricate and multifaceted impact of various digital technologies on schooling.

1. Introduction

Modern technologies like artificial intelligence, machine learning, and big data have made robotics, a concept that dates back to ancient times, much more advanced. The area of robotics, originally used in industrial settings, has now expanded its scope to include a diverse range of industries, such as industrial robots, medical robots, military robots, space robots, and humanoid robots that adopt human-like characteristics.

In accordance with this existing structure, libraries have additionally adopted the use of robots, which have shown enhanced efficacy and capabilities in executing diverse library functions. A significant number of libraries around the world have used humanoid robots to facilitate a variety of library functions, including STEM education initiatives. Academic institutions such as the Chicago Public Library and the University of Rhode Island Library organize programs centered on robotics.

Libraries may become obsolete in the 21st century if they do not begin to harness new technology and improve their information and service delivery. Robots come in a variety of shapes and sizes, and they serve a variety of functions. It is difficult to define the purpose of a specific robot and its categories because each robot has its distinct feature and varies in size, shape, color, and components.

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.

1. Introduction

Traditionally, libraries were considered book storage facilities for kings and other prominent members of society. However, the idea of conventional libraries was altered with the advent of ICT.The development of the Internet, the World Wide Web, and information technology (IT) are assisting in increasing f inancing for studies on creating, accessing, and administeringelectronic information resources. As a result, a new era of digital and virtual libraries has emerged. These technological developments have made it possible for a new generation of information professionals to successfully select, organize, retrieve, and communicate digital content to their target audience (Nazim & Saraf, n.d.). The concept emerged again when computers were connected to tremendous networks to create education and research cantered on creating digital libraries accessible to anybody all over the World. Terms like "virtual library", "electronic library", "library without walls”,and "digital library" have been used to characterize this broad concept (Cleveland, n.d.). Digital Libraries are enormous collections of organized information resources. Elegant “Digital Library” software can enable everyone to perceive, organize, develop, and disseminate new information collection.Libraries have long been seen as safeguards of information, having developed over centuries from private repositories of manuscripts to community centres teeming with activity and education. This evolution has accelerated in the digital age, forcing libraries to negotiate the challenging flows of digital evolution.

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.

1. Web Based Services

People can reach the web, which is short for "World Wide Web," which is a huge network of papers and tools that are all linked together. The web, which was created by Tim Berners-Lee in the late 1980s, changed the way people around the world share and receives information.

The growth of technology has had an impact not only on the formats and sources of the information, but also on the manner in which library services are provided and the locations where they are provided. A portion of libraries and the resources they provide have been relocated to the digital realm created by the Internet. The web works on a client-server model: web computers (clients) ask web servers for web pages and other data and then show them. There are connections between the text, pictures, movies, and apps that make up these tools.

Web development is based on key tools like HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript, which make it possible to make web pages that look good and let you interact with them. Over time, improvements like flexible web design (which makes sure that websites work on all devices) and web APIs (which let different software systems share data) have made the web experience even better.

1. Introduction

Libraries have an outstanding role in the advocacy of sustainability and green practices, now that the place of environmental awareness is on the rise. Green libraries provide a commitment, through sustainable architectural practices, efficient systems in energy saving, measures taken with environmental consciousness to preserve resources, and ways to conserve resources in the work they do. The libraries focus on ensuring they provide healthy indoor spaces and educate their communities on sustainability. Admittedly, it is through the adoption of these practices that libraries minimize their ecological footprint and provide a beacon of environmental responsibility. Green libraries are facilities that take ecologically friendly approaches in carrying out operations and programming in activities targeting environmental responsibility. Such libraries try their best to use methods that diminish energy consumption and lower resource use to move closer to sustainability at its core, which may have less of an impact on the environment. Green libraries have focused on recycling, reduction of trash, renewable sources of energy like solar panels, energy efficiency in lighting and space heating, sustainable building materials, and architectural style.

1. Introduction

The library, often perceived as a tranquil oasis, can be a hotbed of emotions. Behind the scenes, library employees and patrons alike struggle to manage their emotions, and anger can be a particularly pervasive and destructive force. The pressure to meet deadlines, the stress of dealing with difficult patrons, and the frustration of working with outdated technology can all contribute to a simmering sense of anger and resentment. But anger is not just a personal problem, it can have far-reaching consequences for the library as a whole. Unchecked anger can lead to decreased productivity, strained relationships, and even violence. It can also create a toxic work environment, driving away talented employees and eroding the trust of the community. Despite the importance of anger management, it is often overlooked in library training and professional development. Library employees are frequently expected to manage their emotions without being given the tools or support to do so. This can lead to a culture of silence, where employees suffer in silence, afraid to speak out about their struggles with anger.

1. Introduction

A public library is a repository of diversified material that serves as the primary hub for community information the spread. It provides fair access to a wide range of information and data, meeting the diverse demands of users. Services must be inclusive, with information appropriate for all age groups and the incorporation of both classic materials and contemporary technologies across many mediums. In 1987, the ILA defined the purpose of public libraries, stating that they should serve as independent training centers for community activities. Public libraries play a pivotal role in fostering community engagement, welcoming all members to participate in various programs. Initially established by the public, these libraries later received government funding for expansion and other requirements. The systematic development of India's public library system ensued after the establishment of the Raja Rammohan Roy Library Foundation (RRRLF) in 1972.

1. Introduction

The term "sustainable development" was originally used in a 1953 article by Joseph L. that was published in Land Economics. The notion was employed to depict the degree or pace at which an environmentally friendly resource is employed for a particular objective while guaranteeing its long term availability. Organizational dynamics, social interactions, and cultural norms all change with the times. These changes are making environmental problems worse and bringing up questions about pollution and the requirement for a safe natural environment. They are being caused by changing human behavior and population expansion (Kami?ska, 2021; Gaffar et al., 2021). Organizations have been forced to review their approaches to dealing with these urgent environmental issues as a result of the increased awareness. Academic libraries have been particularly well-positioned to implement eco friendly practices because they are service-oriented establishments to adopt eco-friendly practices in their operations (Pangail, 2017).

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).

1. Introduction

The Online Dictionary of Library and Information Science (ODLIS) defines best practice as, “in the application of theory to real-life situations, procedures that, when properly, applied consistently yield superior results and are therefore use as reference points in evaluation of the effectiveness of alternative methods of accomplishing the same task. Best practices are identified by examining empirical evidence of success”. Commonly, best practices are those services, which satisfy the respective users’ community on their desired level. Earlier, best practice term was used in the manufacturing industries for implementation of benchmarking methods so that ultimate quality results may be achieved. But later on the term “best practice” has also been used in academia and other fields as well. The mandate of any library is to work according to the informational needs of the user’s and other facilities, which are desired by the users. The service delivery pattern has totally been changed gradually due to the technological impacts and ever changing needs of the users. Now library users’ wants quality information services, which satisfy their needs so it becomes necessary for any library to provide the satisfactory services in the best and desired way. Best practices can play a major role in the comprehensive development of any academic institute and the agricultural university libraries are not exception to it.

1. Introduction

The advent of computers, the Internet and other ICT technologies have enhanced the nature of tasks. No one is immune from technology. Technologies have paved the way for information transformation. Today every section of society is making full use of technologies to fulfil their needs. Electronic devices have affected human life to a great extent. These devices have changed the working styles of human beings. Working with electronic devices is much better than manual work. Therefore, every sector of human working society is updating itself by using or implementing electronic devices. The higher education department is no exception to this. Today every sector of higher education department is using these modern tools and technologies not only for official works but also for teaching. Library is the most important part of Higher Education Institutions and today the entire structure of the library has changed. Today computersare being used in every section of the library and the main work of the library- issue/return is also being done through the use of computers and the Internet. The resources available in the library have also become electronic. Every resource like books, magazines, research journals, dictionaries, glossaries, bibliographies, biographies, who’s who etc, is now being published in electronic form and the library has to purchase these resources for its users.

1. Introduction

For actively participating in today's global information society, having access to information and information resources is crucial. Information serves as a foundational pillar for the success of any nation, and libraries act as the primary gateways to access information. Libraries have been playing a crucial role for decades in supporting educational, learning, and research activities, as well as catering to the diverse informational requirements of individuals. However, changes in the form and formats of documents as well as diverse needs of users, pose new challenges for libraries in meeting these dynamic needs of their users. Libraries must now reconsider their roles and duties, designing a variety of new innovative services that are crucial for providing value-added, needs-based support to the society. Societal progress depends on research, often described as the lifeblood of communities, as it is vital for offering solutions to various problems.Traditionally, libraries have provided their patrons with information resources. However, in addition to these resources, libraries must now offer a range of services to support the research endeavors of scholars and researchers. In essence, while libraries have historically played a significant role in supporting research, they now must take an active role from the inception of research activities to the dissemination and formal publication of research findings. Achieving this requires not only the redesigning of library services but also the development of new skills among library professionals to proficiently navigate through the flood of information, useadvanced information and communication technologies effectively and offer comprehensive research support services (RSS) to user community.

1. Introduction

In this time of technological advancement, social media has crept into the daily existence of individuals. It is Facebook, Twitter and Instagram which are standard ways of communication to bring people together. The aspect of social media as an auxiliary means of user engagement is also appreciated and embraced by libraries making it part of marketing communication. Using social media, libraries are able to efficiently disseminate information and operate online call centers. There are social media companies which have helped libraries extend their reach especially to young people who are known to be technology-oriented. Thanks to social media, users are able to find value in the services offered by the libraries and this turns out to be beneficial.

1. Introduction

There is an emergence of the concept of a Circular Economy as one of the transformational approaches toward sustainability, where greater emphasis is laid on rethinking and redesigning products and services for maximum resource efficiency. In contrast to the traditional linear model ("take, make, dispose"), CE emphasizes product reuse, recycling, and cascading with the clear ambition of closing the loop of product lifecycles through continuous recovery of resources. The key to this solution involves changing the paradigm, highly relevant to resolving pressing environmental issues facing the planet such as resource depletion, waste management, and climate change.

Conventionally regarded as information stores, libraries are increasing awareness of their potential to create an impact toward sustainable practices. Centres of information and meeting points for communities, libraries are at an advantageous position for leading by example in integrating the principles of CE into their system. This paper examines the current status of integrating the circular economy principles within library management and discusses a proposed conceptual framework that aims to guide libraries in adopting circular practices. The paper addresses the contribution that libraries might make to a more sustainable future by exploring the intersection between CE and library management through innovative practices and strategic plans.

1. Introduction

Information and Communication Technologies (ICT) has transformed the functioning of modern libraries in the 21st century. The applications of ICT to data, information and knowledge resources have given rise to data centers, digital libraries, and knowledge repositories. New software’s that are based on international standards have emerged to undertake a wide range of jobs that suit the requirements of individual libraries. Rapid advances in the application of ICT have given rise to ‘Open Standards and Open Source Software’s. Libraries can benefit a great deal now by using these standards and software, as during the last twenty five years only rich libraries could afford to use commercial software. As a result the transformation of libraries was not universal in India. Now with the advent of open source software, we are expecting many libraries are going to be modernized. This transformation is not going to be limited to libraries only but to users as well who belong to different disciplines and walks of life due to social networking which is emerging as a major activity of libraries around the world. Libraries

1. Introduction

The present library system has been designated as a treasure of knowledge in virtual environment. The concept of modern library has been considered as the source of high level-information using web technology, digitization, networking,e-resources and multimedia. The rapid development of modern information and communication technologies and smart usage of computers in library and information system and services has given rise to new generation of libraries. The last two decades have radically transformed the library system with new avenues of information transfer in virtual world. An incredible amount of growth in increasing new interfaces have been developed utilising latest technologies to optimise the delivery of contents and services in the context of web environment. The emerging new vision of library interfaces has involved web technologies, digital collection of texts and images, documents, genealogy of records and other materials of importance for the user community. The major shift of new technology has developed the subscription of e-journals, e-books, and e-databases collection in libraries. Such library interface is compelled to provide equal access to the contents or these collection to all users irrespective of area or locality. Another remarkable trend in library technology field is the emergence of open-source software movement that enabled to transform the automation and digital library interface. Open Source Software efforts such as OAI, Grenstone, DSpace, Koha etc, have drastically transformed the library technology scenario in terms of sophistication and functionality. This article/ chapter is dealt with the state of digital library system with stages of generation of digital libraries and future directions.

Introduction

A wide range of agricultural pesticides is currently being used in India. In the financial year of 2015, the size of the crop protection market in India was of about $4.5 billion (FICCI, 2016). A large number of these pesticides are also being used in considerable quantity on horticultural crops, including fruit crops. In general, judicious application of a pesticide following Good Agricultural Practices (GAP) does not leave its residues in crop produces above unacceptable limit. But the GAP recommendations are not available for all crop-pesticide combinations. The usage pattern of pesticides also sometimes gets modified at farm level due to sudden climate changes, and under such situations, the indiscriminate use of pesticides to combat disease and insect complex might result in the contamination of pesticides in fruits.

Waste is defined as anything that doesn’t add value to their operations. To the average person, waste is simply stuff that’s unwanted or useless. But from a scientific perspective, there’s really no such thing as waste. Nearly all the things we throw away can be transformed or processed in ways that make them useful again.

Waste comes in various forms, ranging from household trash to industrial byproducts. These include domestic waste, factory waste, e-waste, construction waste, agricultural waste, and more. We can categorize waste into different types:

Solid waste: This includes organic materials like vegetable and kitchen waste, as well as general household waste.

E-waste: Discarded electronic devices such as computers, TVs, and music systems fall into this category.

Liquid waste: This comprises water used in various industries, as well as waste from tanneries, distilleries, and thermal power plants.

Plastic waste: Items like plastic bags, bottles, and containers make up this category.

Introduction

The horticulture sector is contributing over 30 per cent share in agricultural GDP of the country. Presently, India producing about 351.92 million tons of horticultural produce from 28.04 million hectare which has surpassed the food grain production for last five consecutive years (Anonymous, 2023). Horticulture sector has been identified by Government of India also identified horticulture as one of the vital sector for entrepreneurship development, employment generation, livelihood and nutritional security, doubling farmer’s income, achieving SDGs of the United Nations.

Fruits and vegetables have become part of a modern healthy lifestyle as they possess high amounts of minerals, especially electrolytes, dietary fiber, phytochemicals, especially antioxidants, and vitamins (Yahia et al., 2019; Krishnan Kesavan et al., 2023). In consumption, the qualities of products play a critical role in consumers’ choices, which are directly related to health problems (Tian, and Xu, 2022). Bioactive compounds are phytochemical substances present in small quantities in plant materials that can provide biological activity, being generally associated with health benefits, including hepatoprotective, anti-inflammatory, antioxidant, antithrombotic, anticarcinogenic, antidiabetic and prevention of cardiovascular and degenerative diseases (Campoli et al., 2018). Therefore, maintaining high-quality fruits and vegetables is very important for the fruit and vegetable industry. This requires some methods to evaluate the quality of fresh fruits and vegetables during their post-harvest manipulation and storage and before their industrial processing as well (Tian and Xu, 2022).

Introduction

India is bestowed with varied agro-climatic conditions. Thus, horticultural crops have lot of potential in the country. India has witnessed voluminous increase in horticulture production over the last few years, which has undoubtedly doubled the income of farmers. As a result, the country has emerged as the 2nd largest producer of fruits (102.48 million tonnes) after China during 2020-21 (Anonymous, 2023). The abundance of fruits ranging from tropical delights like mango, banana, guava and papaya to temperate fruits such as apple, peach, plum, apricot and pear, have laid a robust foundation for the growth of the fruit processing industry. This chapter delves into the dynamics of fruit processed products in both local and international markets, exploring the challenges, opportunities and strategies for sustained success. Fruit processing plays a crucial role in adding value to horticultural produce, enhancing shelf-life and meeting the diverse demands of local and international markets. In India, a country blessed with abundant fruit varieties, the processed fruit industry has been witnessing significant growth, catering not only to the domestic market but also making strides in the global arena. The processing of these fruits into various products such as juices, pulps, concentrates, jams and dried fruits has emerged as a thriving industry. This chapter will provide insights into the current state of fruit processed products in India, their importance for both local consumption and export markets, challenges faced by the industry and potential avenues for the future growth.

Introduction

Perishable nature of horticultural produce is a major factor contributing in high post-harvest losses. The metabolic processes such as respiration, transpiration, and ethylene production remain active after the harvesting of produce, which drive ripening and senescence Fig. 1. Thus, an effective post-harvest handling is crucial to delay these changes. The rate of these processes depends on the produce’s physiological characteristics, composition, and storage conditions like temperature and humidity. Low-temperature storage is the simplest and most efficient method to slow down deterioration Escobedo-Avellaneda and Welti-Chanes, 2016. Combining low temperatures with methods that limit oxygen exposure, which fuels many enzymatic reactions, further extends shelf life and maintains food quality. Reduced oxygen levels decrease respiration and the activity of enzymes like polyphenol oxidase and peroxidase.

Introduction

The cold chain is a meticulously managed series of actions using specialized equipment to ensure products remain within a specific low-temperature range from production to consumption (ASHRAE, 2024; IIR, 2024). This unbroken sequence encompasses refrigerated production, storage, and distribution activities, safeguarding the safety and quality of perishable and thermo-sensitive goods like agricultural commodities (such as fresh produce, meat, dairy, seafood, chemicals, pharmaceuticals, flowers, wine, etc.), processed foods and pharmaceuticals (Aung and Chang, 2014; Awan, 2023). For climacteric fruits like bananas, custard apples, apples, pears, tomatoes, mangoes, and avocados, cold storage facilitates controlled ripening, extending the time between harvest and consumption. Cold chain management, integral to the overall supply chain, requires expertise in maintaining temperature, air quality, and adherence to regulatory standards. Any disruption in this process can lead to product spoilage and financial implications (FAO, 2019). The management of the cold chain system is crucial for preserving the freshness, taste, and nutritional value of fruits from harvest to consumption (Kader, 2003).

Fruits and vegetables are perishables and the post-harvest losses from the point of production at the farm gate till it reaches the consumers is estimated as 30-35 per cent which constitute a major economic drain of more than 33 billion USD equivalent to Rs 2,40,000 crores annually. In order to reduce the losses at various stages, nanotechnologies have come as potential strategies to minimize the losses while improving the marketability and profitability of perishables. One of the plants derived natural compounds “hexanal” which is known to extend the shelf-life of fruits when it is used as a pre-harvest spray or post-harvest dip as a nano-emulsion. Since, it is a highly volatile compound, efforts were undertaken to entrap the compound in the polymer-based nano f ibres (as nano stickers) or as a cyclodextrin inclusion complex (as nano pellets) in order to preserve the perishables. Further, hexanal vapour was also evaluated to preserve fruits. In this book chapter, various nanotechnologies tested, evaluated and technologies developed over the years are elucidated. Overall, the literature review suggests that use of any of the nanotechnologies delivered as pre-harvest spray, post-harvest dip, nano-stickers, nano-pellets and vapour singly or in combination found to reduce the infestation of post harvest diseases, minimize the losses and extended shelf-life by 2-3 weeks that help the farmers to get lucrative prices due to the late arrival in the market besides significantly improve the productivity and profitability of orchards.

Fruits, the vivid and delightful offerings of the nature, undergo remarkable transformations as they travel from the orchard to our dining tables. These changes indicate the significance of post-harvest physiology, which is the scientific study that reveals the secrets of how fruits behave after they are picked, including the mechanisms that affect fruit quality and how long it may be stored. The next section provides definitions of the various stages and key players involved in the processes of fruit maturity, ripening, and post harvest physiology. These topics will be further explored in the subsequent sub-sections of this chapter.

Fruit developmental physiology

The life cycle of horticultural commodities (fruits and vegetables) can be effectively categorized into three primary physiological stages after fruit set or initiation, namely growth, maturation, and senescence. Still, a lack of obvious differentiation exists among the several stages. Growth encompasses the process of cell division followed by cell enlargement, which determines the ultimate size of the product. Maturation typically begins prior to the cessation of growth and involves various activities across different commodities. The stages of growth and maturity are commonly denoted as the developmental phase. Senescence can be described as the phase in which anabolic biochemical processes transition into catabolic processes, resulting in the ageing and eventual demise of the tissue. Ripening, a term specifically used for fruit, is typically regarded as the initial phase of senescence that occurs during the later phases of development. Defining the transition from growth to senescence is rather straightforward.

Calcium, anti-oxidants and certain enzymes are reported to play vital role in extending the shelf-life of harvested produce of many horticultural crops especially fruits. They help in maintenance of cell wall structure. Being an important constituent of cell wall, in the form of calcium pectate, it helps in maintenance of cell wall structure. Antioxidants are highly beneficial in extending the shelf-life of fruits besides maintaining the quality. Similarly, some enzymes play a key role in preserving the fruit quality and prolonging its market life. As some fruits are catergorized under ‘Low volume high value fruits’, it is essential to extend their shel-flife for reducing the post-harvest losses of fruits and also to reap better remuneration. Thus, it becomes indispensable to review the role of Ca, anti-oxidants and enzymes which are beneficial in keeping the harvested produce afresh for a relatively longer period.

Fruit ripening is a phenomena during which horticulture produce undergoes a series of complex physical and biochemical changes initiated through a series of hormones (Ethylene, auxin, abscisic acid (ABA), gibberellins, jasmonic acid, etc.) to attain maximum physiological maturity and favourable organoleptic properties. These changes lead to alterations in colour, texture, aroma, flavour and nutrient composition. In a nut shell, ripening involves increase in pulp to peel ratio, solubilisation of pectic substances, degradation of complex carbohydrates, organic acids and chlorophyll, accumulation sugars, flavour volatiles, polyphenolic compounds and pigments (carotenoids, xanthophylls and anthocynanins). The extent of these changes guide harvesting, readiness for processing and consumption decisions, with physic-chemical alterations serving as indicators of optimum ripeness. Respiration rate, ethylene and ABA are key regulators of fruit ripening in climacteric and non-climacteric fruits, respectively. In climacteric fruits, ABA interacts with ethylene, influencing the synthesis of ethylene itself. Although there is ample documentation on the involvement of hormones in fruit development and ripening, our understanding of the functions of various hormones throughout growth, maturation, and specific ripening processes remains incomplete.

Plant hormone ethylene is involved in a number of physiological activities within the plant system, ranging from seed germination to fruit development. Ethylene acts as a key player in accelerating fruit ripening by regulating the activities of different enzymes, and is responsible for shortening the shelf life and associated post-harvest losses during the storage of fruit crops. However, all fruit crops have different ethylene production capacities and vary in their response to ethylene. Hence, effective management of post-harvest ethylene is imperative for addressing the global challenge of reducing fruit losses after harvesting. In recent periods, numerous technologies and compounds have been developed for the suppression of ethylene and for enhancing in-situ oxidation of ethylene or inhibiting its production at a receptor level. Among these emerging techniques, the use of sachets, fumigating agents, catalysis and composite films embedded with nanoparticles has been found to be trending, but the use of some of compounds has been limited due to health risks or consumer unacceptance. However, most of these technologies are very costly and are not affordable for marginal farmers and developing nations. In order to address these issues, long term breeding approaches for shelf-life improvement, targeting the tfs, ERFs have been involved. This manuscript fills the knowledge gap by encompassing all the recent progress made in enhancing the shelf life of fruits by managing ethylene during storage.

Multipurpose trees and shrubs are defined as all woody perennials that are purposefully grown to provide more than one significant contribution to the production and/or service functions of a land-use system that they occupy. In agroforestry systems, different species of trees and shrubs can be planted with many types of crops in a variety of patterns. Thus, it is required to know about the methods of propagation and nursery raising, planting and other silvicultural management practices along with the diverse uses of multipurpose trees and shrubs of tropical and subtropical areas before their selection for forestry and agroforestry activities. It is important to select the most suitable tree species since it is not easy to replace them once they have been planted.

MANGIUM (Acacia mangium)

Acacia mangium is a single-stemmed evergreen tree that grows to 25-35 m in height and up to 60 cm in diameter. The bole is usually straight, often fluted near the base, free of branches for up to half its height. Mangium is native to Australia, Indonesia and Papua New Guinea. However, it tolerates varied site conditions and has adaptability to different planting objectives. Mangium shows most vigorous growth on well-drained, fertile soils in high rainfall areas in the humid tropics. It is valued for its rapid growth and has been planted throughout the humid tropics and is a major plantation species in the Asia Pacific. Provenances from Papua New Guinea consistently show better growth in height and diameter.

Human societies over the ages have depleted natural resources in different ways and degraded their local environments. Indiscriminate cutting down of trees and accelerating the construction works lead to global warming and climate change. Climate scientists believe that human-induced deforestation is responsible for 18-25% of climate change. Accumulation of greenhouse gases in the lower atmosphere is the main cause of global climate change. The concentration of these gases in the earth’s atmosphere is increasing, mainly due to deforestation and the combustion of fossil fuels which release carbon dioxide.

The earth receives heat energy constantly from the sun through radiation. Some of the heat is absorbed and some is reflected. Carbon dioxide works like an invisible blanket that wraps around the earth and traps the heat inside, similar to the function of a greenhouse. A greenhouse is a structure that is used in colder climates to grow plants. Even when outside temperatures drop below freezing point, greenhouses are still warm enough inside to grow plants. Greenhouses are made of glass, which allows solar radiation to enter. The heat is trapped inside the greenhouse, allowing plants to grow all the year round. Increasing concentrations of carbon dioxide in the earth’s atmosphere insulate it like a greenhouse, leading to a gradual warming of the earth’s atmosphere. Carbon dioxide is the major greenhouse gas, but there are others as well, including methane and nitrous oxide.

Trees have been used in cropping systems since the beginning of agriculture. Throughout the world, at one period or another in its history, it has been the practice to cultivate tree species and agricultural crops in intimate combination. In the tropics, human beings underwent a transition from hunting/gathering to the use of domesticated plants and livestock. As a part of the process, they cut down trees, cleared the debris by burning and sowed crops in the ash enriched soil. It was the ‘slash-and-burn’ agriculture, a primary forerunner of the present-day agroforestry and a practice that might have originated in the Neolithic period, around 7000 BC.

There are innumerable examples of traditional land-use practices involving combined production of trees and agricultural species on the same piece of land in many parts of the world. Trees were an integral part of these farming systems and they were deliberately retained on farmlands to support agriculture. These practices are now known as agroforestry. However, the ultimate objective of these practices was not tree production but food production.

In agroforestry systems the various components like tree, crop and pasture exist in different proportions and orientations. It is difficult to find out which agroforestry system is the best suited for a given land situation. Similarly, it is to be decided which technologies are required for refinement and improvement of the existing agroforestry practices. But without sufficient knowledge of the existing system in a particular land situation, it is very difficult to set the research priorities for modification and development of this system.

Diagnosis and Design (D & D) is a systematic and objective methodology developed by International Centre for Research in Agroforestry (ICRAF) to initiate, monitor and evaluate agroforestry programmes. D & D is based on the philosophy that knowledge of the existing situation (diagnosis) is essential to plan and evaluate (design) meaningful and effective programmes in agroforestry research for development. The methodology plays a strategic role in all the phases of the agroforestry research process. D & D in agroforestry is unique and it has been specially developed for the following purposes (Raintree, 1987)

A watershed is a geohydrological unit or all the land and water area bounded by a divide which contributes runoff to a common point. Watershed is considered to be synonymous with ‘catchment basin’ and ‘drainage basin’. In watershed management approach, development is not only confined to agricultural lands but also covers the area, starting from the highest point of the land to the outlet of the natural stream. Watershed management becomes increasingly important as a way to improve livelihood of people while conserving and regenerating their natural resources.

Watershed management is the process of creating and implementing plans, programmes and projects to sustain and enhance watershed functions that affect the plant, animal and human communities within a watershed boundary. It implies the judicious use of all the resources,i.e., land, water and vegetation in an area to prevent soil erosion, improve water availability and increase food, fodder, fuel and timber on sustained basis.

Ecology of a place is influenced by a number of biotic and abiotic factors. An agroecological zone is broadly homogeneous in climatic and edaphic factors, but not necessarily contiguous, where a specific crop exhibits roughly the same biological expression. On the other hand, the characteristics of an agroecological zone influence the crops and cropping patterns of the zone. Thus, there are considerable variations in the types and management practices of agroforestry systems being followed in different agroecological zones.

AGROFORESTRY FOR HUMID AND SUBHUMID TROPICS

Humid and subhumid tropical regions have much variation in biological, social and economic parameters. The characteristics of humid tropics include high mean annual rainfall of more than 1500 mm, dry season of less than four months in a year and mean annual temperature of more than 22°C. Rainfall usually exceeds the evapotranspiration. However, demographic pressure has caused excessive deforestation and overgrazing which developed soil related problems like low soil fertility, low organic matter, high acidity and high rainfall erosivity. The agroforestry practices designed for this region should aim for improved fallows, soil fertility improvement and conservation, food production, etc. Thus, the common agroforestry systems in this zone are taungya, homegardens, alley cropping, plantation-crop combination, windbreaks, silvipastoral systems and various intercropping systems. Shifting cultivation is a common practice in tropics which should be discouraged as it causes environmental degradation and ecological imbalance, soil erosion and soil nutrient loss.

Agroforestry is a land use system that involves two or more plant species at least one of which must be a woody perennial. When perennial woody and herbaceous components are grown together on the same piece of land their performance would largely depend on their ability to share various growth resources in a given environmental situation. Due to difference in growth pattern and resource requirement of the components in agroforestry situation, a close interactive relation is obvious. Thus, careful management practices for the components are required to establish a successful agroforestry system. The characteristics of the trees and crops, and their interactions, can be modified with good management practices in order to take advantage of the positive characteristics and minimize the effects of the negative ones. Effective and efficient agroforestry management may be divided into two groups; tree management and agricultural crop management.

All agroforestry systems are characterized by three basic sets of attributes; productivity, sustainability, and adoptability (Nair, 2008).

Productivity: The majority of agroforestry systems, if not all of them, strive to maintain or raise both land productivity and output (of desired commodities). In several aspects, agroforestry may raise production. These include higher yields of related crops, less input use in the cropping system, enhanced labour efficiency, and higher production of tree products.

Sustainability: Agroforestry can achieve and indefinitely maintain conservation and fertility goals by conserving the production potential of the resource base, mainly through the beneficial effects of woody perennials on soils.

Adoptability: Improved or new agroforestry technologies that are introduced into new areas should fit the social as well as environmental characteristics of the land use system for which it is designed and should also confirm to local farming system.

Agroforestry systems are not simply systems where trees and crops or animals give useful products to the farmers, rather systems where trees and crops and/ or animals interact. Interaction literally means influence or mutual or reciprocal action. So, component interaction refers to the influence of one component of a system on the performance of other component as well as the system as a whole.

In agroforestry systems, trees are grown in close proximity to crops and pasture. Their performance would largely depend on their ability to share various growth resources in a given environmental situation. Various interactions take place between the woody trees and herbaceous plants (crops or pastures) which is referred to as tree-crop interface. These interactions take place through the media of soil and microclimate and may exert favourable or adverse effects on the crop. Study of interaction helps to know how the components of agroforestry utilize and share the resources of the environment, and how the growth and development of any of the components will influence the others. Interaction occurs both above and below the ground and includes a complex set of interactions relating to radiation exchange, the water balance, nutrient budget and cycling, shelter and other microclimatic modifications.

Management approaches to soil, including problems of soil degradation and low soil fertility, have recently undergone major changes. The earlier concept was to concentrate on achieving high levels of production from the more fertile areas, leaving the marginal lands for extensive use only. Steeply sloping and highly drought-prone areas were mostly left without any cultivation as production from these areas was hardly cost effective. Soil constraints were to be overcome by inputs like improved crop varieties, fertilizers, chemical control of pests and diseases, and the use of irrigation.

The approach of use of newly developed high yielding crop varieties, improved agronomic management practices, use of chemical fertilizers, efficient water management and timely plant protection measures has been successful in achieving large increases in crop productivity in recent years. On the other hand, continuous application of fertilizers at higher rates leads to environmental problems. Yield responses to fertilizers have declined because of soil physical degradation and micronutrient deficiencies. Above all, large numbers of poor farmers simply can neither afford high levels of fertilizers and other purchased inputs, nor do they have the capital to take on the risk involved in their use. Increasing the area under irrigation has also run into severe constraints in the form of limits to available freshwater resources.

The idea of social forestry is not new in India. It may be found in Lord Buddha’s teachings from around 2500 years ago. According to Buddha’s teachings, a devout Buddhist should plant one tree and nurture it for five years so that it matures into a complete tree. By doing this, a person should plant around f ive trees over his lifetime. It is also believed that the Great Emperor Ashoka planted fruit trees and shade trees by the roadsides for the benefit of passing travellers.

The rural economy in India has been largely supported by forests. In the past, the local people kept an ecological balance while managing their woods to provide food, fuel, fibre, fodder, timber and herbal remedies. However, India’s forests have rapidly disappeared due to biotic pressure from expanding human and animal populations, a lack of technical skills, insufficient investments, and ownership changes. In addition to biotic pressure, other factors that led to the depletion of forest resources includes inadequate scientific and technical inputs; staff lacking the necessary skills and training to assume their expected new roles; poor investment in forest development; and damage from mining, irrigation projects, industries, roads; and shifting cultivation. As a result, in the early 1970s, new ideas in forestry development were introduced. Therefore, a variety of activities were incorporated in social forestry initiatives, including planting trees on agricultural bunds and roadsides, creating woodlots on shared lands, and integrating local people in the gathering, processing, and management of forest products.

Farmers have been growing trees for different purposes for thousands of years. Tree species that are grown to provide more than one significant function are called multipurpose trees. These functions may be productive such as producing fuelwood, timber, fibre, fodder, food, medicine, etc. and/or protective such as soil conservation, shade, shelterbelt, microclimate amelioration, land sustainability, biodiversity preservation, etc. All trees are multipurpose; some, however, are more multipurpose than others. Tree species can be multipurpose in two ways.

1. A single tree can provide more than one function. For example, Gliricidia sepium is grown as living fences that provide fuel, fodder and green manure for agricultural crops - all at the same time.

2. Trees of the same species, when managed differently, can provide different functions. For example, Leucaena leucocephala is managed so that some trees will mainly yield wood while others mainly produce leaf fodder.

It is vital to categorise agroforestry and its many systems in accordance with certain contemporary standards in order to have a thorough grasp of them and to enable future progress. Since each agroforestry system refers to a different set of agroforestry practices involving agriculture (crops), forestry (trees), and pasture (animals), the various uses of land are combined either temporally or spatially. Each agroforestry system has its own unique arrangement of various components, such as crops, animals, perennial trees, etc., and degree of interaction between the components. In terms of structure, composition, age intensity, technology, inputs, etc., one system varies from the other.

Creating a useful framework for the synthesis and analysis of data on current systems as well as the creation of new, promising ones should be the primary goal of classification. For this reason, every categorization system needs to have the accompanying the following standards.

A scientific evaluation of the physical characteristics of the land, the properties of the soil, and the management techniques is called land capacity categorization. Understanding potentiality, capacity, and appropriateness for the best possible use of land is the primary goal of land capability categorization. Measuring land capacity provides an objective assessment for land preservation in certain ecological scenarios.

On the one hand, land capacity aids in determining if a piece of land is efficient for a certain use, and on the other, it aids in preventing inappropriate use of the land, which poses a risk of erosion and degrades the quality of the land. Therefore, in order to maximise production, each piece of land’s potential should be assessed taking into account both its pedo-geomorphic characteristics and any constraints resulting from environmental threats. Additionally, under the necessary management practices, capacity categorization allows farmers to use the land appropriately for sustainable output.

Agroforestry is a very old practice, dating back many years. Tropical farmers have long been growing food crops, timber, and livestock in addition to taking advantage of the variety of products that may be obtained from natural wood lots. Indian culture is deeply rooted in its appreciation of trees and forests. The forests gave birth to the greatest aspects of Indian culture. The sages who developed Hindu philosophy resided in forests, living in perfect harmony with the natural world. In fact, trees have been discussed in our ancient literature so much that people were planting trees on their own in addition to crops for agriculture. Maharishi Kashyap’s book ‘Krishishukti’ divides land into multiple categories and designates regions that are suitable for tree planting. Particular sites for planting trees include all wet and dry regions as well as the vicinity of homes, wells, and tanks. However, foresters and farmers, who have historically worked within very strict disciplinary boundaries and focused on producing their favoured commodities - crops, livestock, and trees - used to disregard such integrated production systems that incorporate many disciplines.
