Introduction

Nanotechnology is a rapidly expanding branch of science that has a critical role to play in raising the standard of living for people in the modern world. The global market for nanotechnology in food packaging is valued at 20 billion in 2023 and is expected to grow to 46.50 billion by 2031, with a compound annual growth rate (CAGR) of 11.32% from 2024 to 2031 (InsightAce Analytic, 2023). The rapid expansion of nanotechnology has paved the way for number of industrial areas, including food processing, food contact materials, and agricultural output (Mohammadi & Jafari, 2021). Nanotechnology is the fastest-growing field of science that significantly enhances the quality of life in today's world. This rapid advancement has opened up numerous industrial sectors, such as food processing, food contact materials, and agricultural production. A natural advancement is the integration of nanotechnology into food packaging. This includes enhanced packaging, active packaging, and a new category known as smart or intelligent packaging. Food contact materials, such as antimicrobial metals and oxides, biodegradable nanocomposites, and nanosensors, are utilized to create active and intelligent packaging. These materials enhance thermal and mechanical durability, increase safety and extend the shelf life of food, and facilitate the monitoring of packaged food (Kah et al., 2013). At the nanoscale, material properties change significantly, making it challenging to predict, identify, evaluate, and manage the health, safety, and environmental risks associated with nanomaterials. For example, nanoparticles (NPs) of 50 nm can enter cells, those of 70 nm can penetrate the lungs, and 30 nm NPs can cross blood-brain barriers.

Introduction
The use of liposomes as carriers for drug delivery has had a profound impact on the pharmaceutical industry. In 1961, Alec Bangham made a significant contribution to the field by introducing liposomes, which sparked a wave of research and development in this area (Bangham, 1992). Over time, liposomes have become incredibly versatile in their ability to transport drugs, biomolecules, and gene therapies. This groundbreaking approach has not only enhanced the effectiveness of treatments but also minimized side effects by precisely targeting specific sites within the body (Lai et al., 2024). Liposomes are vesicular structures composed of one or more concentric lipid bilayers that enclose an aqueous core. Hydrophilic drugs are commonly found within the aqueous compartments, whereas hydrophobic drugs are incorporated into the lipid bilayers. The innovative design of this architecture enables flexible drug encapsulation and precise delivery to specific targets. Liposomes have a wide range of applications in medical science, going beyond drug delivery to encompass diagnostics and vaccines. This versatility greatly enhances their value in the field (Gupta et al., 2023).
An important milestone in liposomal delivery technology occurred in 1995 with the approval of Doxil, which was the first-ever liposomal drug delivery system. Since then, there have been notable advancements in improving the physicochemical properties of liposomal formulations. Although there have been advancements in this field, it is important to remember that the core principles established during Doxil’s approval are still relevant for all liposomal delivery systems. These principles encompass the importance of stability, achieving optimal drug release kinetics, and ensuring biocompatibility and safety (Barenholz, 2012; Wang et al., 2022).
First and foremost, stability is of utmost importance. It is crucial to ensure that liposomal formulations remain intact throughout storage and administration in order to maintain the integrity of the drug and avoid problems such as leakage or degradation. The stability of liposomes can be affected by various factors, including the lipid composition, preparation method, and storage conditions. Ensuring stability necessitates the implementation of advanced manufacturing processes and rigorous quality control measures (Liu et al., 2022).
In addition, it is crucial to achieve the ideal drug release kinetics. Striking the perfect balance between sustained release and efficient delivery to the target site is crucial for optimizing therapeutic benefits and minimizing any potential adverse effects. Designing liposomes to release their payload in a controlled manner, customized to the pharmacokinetics of the encapsulated drug, is a crucial aspect of this process. Optimizing factors like liposome size, surface charge, and the inclusion of targeting ligands can greatly enhance the release profile (Pande, 2024).
Furthermore, ensuring biocompatibility and safety is of utmost importance. It is crucial to conduct comprehensive safety evaluations to ensure that liposomal systems do not trigger immune responses or lead to any adverse reactions. The lipid composition and surface characteristics of liposomes play a crucial

Introduction

Engineered nanoparticles are a group of products that are defined by their size, ranging from 1 to 100 nm. Due to the smaller size, the physio-chemical properties of nano particles become very different from those of the same material in a larger form. Total production of nano-materials is expected to increase considerably in the near future. Nanotoxicology is yet another emerging field of science dealing with the effects of nano-devices and engineered nano-particles on living organisms. It has been observed that the materials in nano-dimensions react totally different in comparison to their existence in micro or macro sizes.

Introduction

Food packaging is one of the most dynamic and fast-growing industries in the current scenario of increasing industrialization. With the constant upsurge in the food wastage at different stages of processing (suchas harvest, storage, processing, transportation, and distribution) leads to more than 15% of food produced ending up in the dumping grounds due to food spoilage caused by climatic conditions andmicroorganisms.Ever-increasing demands of consumers for convenient food makes packaging technology a need of the hour in order to keep the food safe, wholesome and of high quality at the same time.

So appropriate packaging has the potential of not only preventing spoilage but also taking care of healthand well-being of the individuals.Therefore, packaging plays the most important role in the overall safety of the food product.This makes packaging as the ever-evolving field since new requirements need new materials which demands new approaches and technology for better quality products.

By definition, Food packaging is a well-organized system of protecting the food product from any kind of physical, chemical, and biological damage in order to ensure that food reaches the consumer in its most safe condition at minimum applicable cost. It is bridge between production and consumption (Paine, 1992).

Abstract
Aquaculture has emerged as a key solution for meeting the rising global demand for aquatic food products, contributing significantly to food security. However, its rapid growth faces significant challenges from climate change, including rising temperatures, ocean acidification, extreme weather events, and habitat degradation, which threaten production systems and the livelihoods dependent on them. This chapter explores the role of regulatory frameworks in mitigating climate impacts, promoting sustainability, and enhancing resilience in aquaculture. It emphasizes the importance of integrating aquaculture into national and global climate adaptation plans, adopting ecosystem-based approaches, and fostering innovative practices like integrated multi-trophic aquaculture (IMTA) and cultivating climate-resilient species. The chapter highlights the need for advanced tools, such as climate monitoring systems and genetic advancements, to mitigate risks while ensuring resource efficiency and productivity. Addressing barriers like complex governance structures and limited resource access is essential for effective policy implementation, particularly in vulnerable regions. By combining robust legal instruments, technological innovations, and community-based governance, aquaculture can transition toward a sustainable and climate-resilient future, ensuring long-term environmental health, economic stability, and social equity while continuing to play a vital role in global food systems.

This guidance explains when a botanical drug may be marketed under an over-the-counter (OTC) drug monograph and when FDA approval of a new drug application (NDA) is needed. In addition, this document provides guidance to sponsors on submitting investigational new drug applications (INDs) for botanical drug products, including those botanical products (or botanicals) currently lawfully marketed as foods and dietary supplements in the United States. This guidance also discusses several areas in which, because of the unique nature of botanicals, FDA finds it appropriate to apply regulatory policies that differ from those applied to synthetic, semisynthetic, or otherwise highly purified or chemically modified drugs (including antibiotics). In particular, the guidance states that applicants may submit reduced documentation of preclinical safety and of chemistry, manufacturing, and controls (CMC) to support an IND for initial clinical studies of botanicals that have been legally marketed in the United States as dietary supplements or cosmetics without any known safety concerns.

I. CHALLENGES TO CYBERSPACE

The problems and prospects of copyright and information technology need to be deliberated in the context of present day jurisprudence. The subject is referable to the extensive use of information technology all over the world which has resulted in enhanced efficiency, effectiveness and optimum use of resources. The copyright law is concerned with the negative right of preventing copying of the physical material in the field of literature and arts. Trade and Merchandise Marks Act protects the patent, trade mark and design giving the registered proprietor an exclusive right to the registered material. The prohibition contained in rights in patent and copyright extend to the unauthorised manufacture or reproduction, so long as the exclusive right rests. Copyright has been held to be not the mere creature of the statute but a natural and civil right. The moral basis of the copyright is that the man is entitled to the fruits of its mental faculties as much as he is entitled to the fruits of his mechanical labour. The law rests on the English Commandment - thou shall not steal. It does not permit one man to make a profit and appropriate himself what has been produced by the labour, skill and capital of another. Blackstone in his commentaries Vol.II at page p.406 has stated:

There is still another aspect of property and this is the right which an author may be supposed to have in his own original literary compositions: so that no other person without his leave may publish or make profit of the copies. When a man by the exertion of his rational powers has produced an original work, he seems to have clearly a right to dispose of that identical work as he pleases and any attempt to vary the disposition he has made to it appears to be an invasion of that right.

INTRODUCTION

The current food crisis has put the agriculture production on a tight leash, not allowing the producers any lassitude whatsoever. Even though we have outgrown from our ‘ship to mouth existence’; our least negligence can torpedo our efforts to maintain the steady state of progress achieved in food grain production. Around 35% of what is produced is lost due to pest and diseases. In this situation, plant protection assumes significance. Unfortunately our plant protection regime begins and ends with pesticides. It is the default option in the plant protection menu and all the other options more or less remain defunct and unused. Even though, our major thrust areas of plant protection are promotion of Integrated Pest Management: ensuring availability of safe and quality pesticides for sustaining food production from the ravages of pests and diseases, streamlining the quarantine measures for accelerating the introduction of new high yielding crop varieties, besides eliminating the chances of entry of exotic pests; we remain largely insulated from these aspects in IPM.

With the Globolization and liberalization in International trade of plants and plant material in the wake of Sanitary and Phytosanitory (SPS) Agreement under WTO, the plant quarantine measures have become more imperative. Liberalization of trade policies have helped the world agriculture trade to prosper which is key sector for many countries like India whose economies are dependent on agrarian industry. But the likehood of the presence of disease/pest inherent in the import material can very well geopardize the trade. Activities are meant to help agricultural development and Plant quarantine service are charged with the responsibility of preventing the entry of hazardous pests, pathogens and weeds, but to deny entry of valuable genetic re-sources would be against national interest. These activities are meant to help agricultural development and they are complementary to each other and therefore are necessary, and we on our parts need to be fairly vigilant. As has been very truly said-An ounce of prevention is worth a pound of cure.

Plant Quarantine
The term ‘Quarantine’ is derived from the Latin word quarantum, meaning 40. It refers to the 40 days period of detention of ships from countries with bubonic plague and cholera in the Middle Ages. The first such quarantine was imposed in Venice in 1374.Present quarantine laws now include plants. Plant quarantine , restrict entry of plants, plant products, soil, cultures of living organisms, packing materials, and commodities, as well as their containers and means of conveyance to protect agriculture and the environment from avoidable damage by hazardous organisms.They exclude dangerous organisms while permitting plants and plant products to enter. The term exclusion convey this objective more clearly than plant quarantine. Exclusion relates to keeping organisms out; plant quarantine relates to keeping plants out.
In strict sense ‘Plant Quarantine’ refers to the holding of plants in isolation until they are believed to be healthy. Now, broader meaning of the plant quarantine covers all aspects of the regulation of the movement of living plants, living plant parts/plant products between politically defined territories or ecologically distinct parts of them. Intermediate quarantine and post entry quarantine are used respectively to denote the detention of plants in isolationfor inspection during or after arrival at their final destination.

Toxicological screening is essential for the development of new drugs (ND) and exploring the therapeutic potential of existing compounds.While animal testing is still regarded as the “gold standard” in traditional toxicity assessments, there is a growing need to transition towards alternative methods for drug safety testing. This shift is driven by the emergence of cutting-edge technologies and the adoption of the 3Rs principle (replace, reduce, refine) which emphasizes animal welfare.Routine in vitro safety screeningalong with GLP (Good Laboratory Practice) and non-GLP toxicity testing follow regulatory frameworks established by agencies such as the FDA (Food and Drug Administration), ICH (International Council for Harmonization)and EMA (European Medicines Agency) (Tang et al., 2023).In recent years, there has been a shift towards enhanced safety screening during the lead optimization stages of drug discovery. Regulatory toxicology testing plays a pivotal role in determining the potential risks associated with new drug compounds and ensuring their safety before they can proceed to human clinical trials and, ultimately, be marketed to the public.

ABSTRACT

North-Western Himalayas have a large area which are degraded and bouldry. Such areas are not fit for crop production. These areas are generally kept unutilized and hence are invaded by uneconomic and invasive species. These lands can be brought under production though establishment of silvipastoral system which has a potential of fodder, fuel and timber production besides conserving natural resources. The paper discusses the techniques of establishment, management and production potential of silvipasture systems in north-western Himalayas.

India has witnessed tremendous increase in the production of horticultural crops especially fruits since independence. Due to specialized scientific interventions and application of latest research tools, the country is now among the top fruit producing countries of the world ranking second next only to China. However, the productivity has still remained low as against area under the fruit cultivation. Several neglecting issues related to the production technology have remained unattended so far. The old and senile orchards are now reverting towards a declining trend of production because of plant age factor, non-compatible varieties and poor canopy management (Baba et al., 2011).

In the recent past declining productivity of old and dense orchards existing in abundance has become a matter of serious concern for the orchardists, traders as well as scientists. In India 30-35 per cent area under fruit crops is occupied by old, dense and diseased orchards. For overcoming the problem of unproductive and uneconomic orchards existing in abundance, large scale uprooting and replacement with new plantations (rehabilitation) will be a long term and expensive strategy. Therefore research efforts were initiated to standardize a technology for restoring the production potential of existing plantations by a technique called Rejuvenation. The term ‘Rejuvenation’ means renewal or making new or young again. As applied to the orchard tree it would mean restoring the productive capacity of the fruit trees. The meaning of ‘Rejuvenation’ according to Chamber’s dictionary is ‘to recover youth character or to grow again’. Obviously, this would apply to those plants which have attained a stage where they are no more profitable from the grower’s point of view.

18.1 INTRODUCTION

The decline in productivity of old and senile orchards existing in abundance has become a matter of serious concern for the orchardists, traders as well as scientists. In India 30-35% area under fruit crops is occupied by old, senile, and pest-and-disease- affected orchards. For overcoming the problem of unproductive and uneconomic orchards existing in abundance, large scale uprooting and replacement with new plantations will be a long term and expensive strategy. Thus, rejuvenation of old and senile orchards is a good alternative.

Pruning in young tree during initial stage help to form a strong frame work for better growth and development of the tree. However, on long term way, the tree becomes huge with gigantic canopy results in to problem of majority of agronomic operation, plant protection and harvesting of crop. Top working provides an opportunity to control the growth of tree and makes the tree productive with manageable canopy, in old and senile orchards.

Top working is a technique evolved to rejuvenate the unproductive and senile cashew trees. Poor yielding trees of 5-15 years of age can be successfully rejuvenated by top working. The unproductive trees are to be headed back to a height of 1.00 m from the ground level in October-November. The stem should be sawed off to avoid stump splitting. Soon after beheading, the stumps and cut portions should be given a swabbing with carbaryl 50% WP (50 g each per litre of water) or Bordeaux paste. Sprouts emerge 30-45 days after beheading. Sprouting will be profuse in young trees. So, it is better to keep only 4-6 healthy shoots on beheaded tree spreading in all directions and similarly the sprouts which come out from ground level (most probably water shoots) also removed frequently. On 30-45 day old shoots, graft scions of high yielding varieties following soft wood grafting technique. On each tree, 4-6 grafts are to be done to ensure at least 3-4 successful grafts per tree. The best season for grafting is March-April. Thinning of the extra shoots arising from the stumps should be done to obtain better growth of the grafts. Removal of sprouts below the graft joint and removal of polyethylene strip from the graft joint should be done. Top working is simple and can be done by farmers themselves after getting proper training. The top worked trees start yielding right from the second year of top working. Early bearing can be treated as one of the best advantages of this technique. The major disadvantage associated with top working is the huge casualty of trees due to stem borer attack. Intensive care and management to ward off stem borer is essential. As such adoption of top working on a larger scale would be difficult.

9.1 Introduction

India is a vast country and is gifted with a variety of soils and climates. Thus, almost all kinds of fruits can be grown successfully in this country. It is a matter of great surprise that in spite of provision of adequate resources, the per capita consumption of fruits here is perhaps one of the lowest in the world.

The existing orchards are not able to meet the present requirements of the country. Poor selection of planting material, haphazard plantation and poor management has made many orchards uneconomic. The term ‘Rejuvenation’ means renewal or making new or young again.

As applied to the orchard tree it would mean restoring the productive capacity of the fruit trees. The meaning of ‘Rejuvenation’ according to Chamber’s dictionary is ‘to recover youth character or to grow again’. Obviously, this would apply to those plants which have attained a stage where they are no more profitable from the grower’s point of view.
