Global onion research connects crop domestication, genetic diversity, nutrition, therapeutics, production, breeding and post-harvest technology. Onion contains organosulphur compounds, quercetin derivatives and other phytochemicals associated with antimicrobial, antioxidant, cardioprotective and anticancer effects. Despite high global production, productivity differs substantially among countries, and storage losses remain a major economic concern. This chapter reviews global production trends, germplasm resources, breeding strategies, phytochemistry, therapeutic potential and emerging storage technologies. Landraces, cultivars and wild relatives provide valuable traits for yield, storability and stress resilience. Advanced treatments such as ozonation, cold plasma and irradiation demonstrate promise, although wider commercial adoption, economic validation and regulatory development remain necessary.

This chapter examines the major global challenges affecting agricultural productivity and food security. Climate variability, extreme weather events, declining natural resources, and changing pest and disease patterns create substantial risks for farming systems. The chapter discusses sustainable and climate-smart agricultural approaches for improving resilience and resource-use efficiency. It also highlights the contribution of artificial intelligence, precision agriculture, biotechnology, remote sensing, and digital technologies in addressing these challenges. Policy support, research investment, institutional cooperation, and equitable access to technology are emphasized for sustainable agricultural development

The escalating global threat of drought, characterized by increasing frequency and severity, demands a comprehensive and coordinated response. These prolonged periods of water scarcity not only endanger human lives and erode livelihoods but also inflict lasting damage on fragile ecosystems. Recognizing the scale and complexity of this challenge, a multitude of global initiatives have emerged, uniting international organizations, governments, research institutions, and civil society in a collective endeavor. This chapter will delve into the landscape of these crucial efforts, exploring the key organizations driving change, the diverse strategies being implemented, and the pivotal role of technological advancements in mitigating the devastating consequences of drought. By examining the framework of these global collaborations, we aim to provide a comprehensive understanding of the ongoing work to build resilience and ensure a more water-secure future for all.

Monsoons are vital atmospheric circulations that govern the climate and livelihoods of vast populations across the globe. Characterized by seasonal reversals in wind direction and associated shifts in precipitation patterns, these systems are critical for agriculture, water resources, and overall socio-economic stability in many regions. However, the delicate balance of monsoon systems is increasingly threatened by climate variability, leading to significant disruptions and challenges, particularly in the form of severe droughts. Recent years have witnessed the devastating impact of drought in numerous monsoon-dependent regions across the world. In India, heavily reliant on the summer monsoon, failures have caused significant water shortages and poor crop yields, particularly in vulnerable regions like southeastern Maharashtra and Rajasthan. The consequences extend to groundwater depletion and increased irrigation demands. The impact of recent droughts is not limited to Asia. The African continent has also faced severe consequences. The Horn of Africa experienced a particularly devastating drought from October 2020 to 2023, resulting in widespread harvest failures, livestock losses, and displacement, marking the worst drought in four decades. West Africa has similarly suffered from frequent droughts causing crop failures, rising food prices, and exacerbating income inequality. South America, too, has experienced significant impacts. Argentina faced a severe drought in late 2022 and early 2023, halving wheat and soy harvests and impacting exports. In Uruguay, this drought led to a lack of access to drinking water for thousands. Brazil has seen harvest failures and reduced agricultural GDP due to drought, also threatening its hydroelectric power generation. Furthermore, the Amazon rainforest has been affected by intensifying droughts, leading to increased tree mortality, a higher risk of forest fires, and significant impacts on biodiversity and local communities due to drastically reduced river levels. Recent years have witnessed the dual impact of extreme weather events in numerous monsoon-dependent regions. In India, while facing drought in many areas, heavy monsoon rains have also caused catastrophic flooding. In July 2021, the coastal regions of Maharashtra experienced severe flooding affecting millions and causing hundreds of deaths. Major events like the 2022 Assam floods and the 2023 North India floods further exemplify the destructive potential of intense monsoon rainfall. The African continent also experiences significant flooding during its monsoon seasons. In 2024, West and Central Africa, including countries like

Abstract
The rapid increase in global food demand, driven by fast population growth, has made it challenging to provide nutritionally balanced diets. Pulses offer a promising solution to these challenges by delivering significant nutritional and physiological benefits. Pulses such as chickpeas, green gram, peas, horse gram, beans, lentils, black gram, and others are excellent sources of protein (190-260 g kg−1), carbohydrates (600-630 g kg−1), dietary fibers, and bioactive compounds. The phytochemicals found in pulses, including flavonoids, phenolics, tannins, phytates, saponins, oxalates, peptides, and enzyme inhibitors, offer numerous health benefits. Pulses, essential to human diets for centuries, have seen historically low consumption levels due to underappreciation of their nutritional value. Recognizing their significance, the United Nations designated 10 February as World Pulses Day, and declared the year, 2016 as International Year of Pulses emphasizing their role in promoting healthy diets, sustainable food production, and food security. India is the largest producer of pulses in the world accounting for 25% of the global pulse production. The production and productivity of pulses have slightly decreased due to great emphasis to rice and wheat crops. To boost pulse production, India has implemented initiatives like the National Food Security Mission and policies to support farmers, including Minimum Support Prices (MSP) and welfare schemes integrating pulses. These efforts aim to enhance pulse cultivation, ensure food security, and improve farmer incomes, addressing the demand-supply gap and declining per capita availability of pulses.

GPS stands for Global Positioning System, basically Navstar GPS is a radio based space aviation system developed by United state government which was operated by United State Air Force. It provides geographic location and time related information to GPS receivers under global navigation satellite from anywhere of earth where unobstructed line of sight to 4 or more GPS satellite co-ordinate (Anonymous, 2018). Even GPS not required any user for transmitting data, with working independently on any telephonic or internet receivers; through these technologies we can enhance usefulness of the GPS location based information. The GPS serves as critical positioning capacity to various fields like army operation, civil aviation, and commercial scope to wider scope in around world.

Introduction

The Global Positioning System (GPS) is a space-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver. The US began the GPS project in 1973 to overcome the limitations of previous navigation systems, integrating ideas from several predecessors, including a number of classified engineering design studies from the 1960s. The U.S. Department of Defense (DoD) developed the system, which originally used 24 satellites. It became fully operational in 1995. Roger L. Easton, Ivan A. Getting and Bradford Parkinson of the Applied Physics Laboratory are credited with inventing it.
 
Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS and implement the next generation of GPS Block IIIA satellites and Next Generation Operational Control System (OCX). Announcements from Vice President Al Gore and the White House in 1998 initiated these changes. In 2000, the U.S. Congress authorized the modernization effort, GPS III. In addition to GPS, other systems are in use or under development. The Russian Global Navigation Satellite System (GLONASS) was developed contem-poraneously with GPS, but suffered from incomplete coverage of the globe until the mid-2000s. There are also the planned European Union Galileo positioning system, China’s BeiDou Navigation Satellite System, the Japanese Quasi-Zenith Satellite System, and India’s Indian Regional Navigation Satellite System.

Introduction

Global Positioning System (GPS) is a system of satellites and ground stations that provide location and time information for any place on earth, regardless of the weather. GPS is a type of GNSS, which stands for global navigation satellite systems. GPS has many applications in precision farming, such as farm planning, field mapping, soil sampling, tractor guidance, crop guidance, variable- rate applications (VRAs) and yield mapping. GPS helps farmers work in low- visibility conditions such as rain, dust, fog, and darkness. India has its own GPS system called IRNSS or NavIC, which uses about seven satellites. GPS is owned and operated by the U.S. government, specifically the U.S.

SUMMARY

Plant tissue culture mainly comprises a set of in vitro techniques, methods and strategies that are part of the group of technologies called plant biotechnology. Tissue culture has been exploited not only to create genetic variability from which crop plants can be improved but also to improve the state of health of the planted material and to increase the number of desirable germ plasms available to the plant breeder through a shorter duration in cost effective manner. Tissue-culture protocols are available for most crop species, although continued optimization is still required for many crops, especially cereals and woody plants. Tissue culture techniques, in combination with molecular techniques, have been successfully used to incorporate specific traits through gene transfer. In vitro techniques for the culture of protoplasts, anthers, microspores, ovules and embryos have been used to create new genetic variation in the breeding lines, often via haploid production. Cell culture has also produced somaclonal and gametoclonal variants with crop-improvement potential. The culture of single cells and meristems can be effectively used to eradicate pathogens from planting material and thereby dramatically improve the yield of established cultivars. Large-scale  micropropagation laboratories are providing millions of plants for the commercial ornamental market and the agricultural, clonally-propagated crop market. With selected laboratory material typically taking one or two decades to reach the commercial market through plant breeding, this technology can be expected to have an ever increasing impact on crop improvement as we approach for the need of the hour .

6.1 World Trade Organization (WTO) and Trade-Related Aspects of Intellectual Property Rights (TRIPS)
6.1.1 Introduction
The globalization of trade and the rapid advancement in innovation—particularly in biotechnology—have necessitated the harmonization of intellectual property rights (IPR) across nations. The World Trade Organization (WTO), established in 1995, is the apex multilateral body that regulates international trade among member states. Within its legal framework, the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) plays a foundational role in setting minimum standards for IPR protection and aligning national laws with global trade norms.
In the realm of biotechnology, TRIPS has profound implications on patentability of life forms, technology transfer, public health, biodiversity, and traditional knowledge.
6.1.2 World Trade Organization (WTO): An Overview

Global warming is the hottest issue facing life in our times. The gradual average increase in air temperatures near Earth’s surface over the past one to two centuries is leading to the phenomenon called global warming. It is this global phenomenon that triggers climate change, threatening the entire life on Earth. Earth’s climate has changed over all conceivable geological timescales, but that was all on account of the natural phenomenon. But, human activities are making the phenomenon more pronounced since the beginning of the Industrial Age, now emerging as a dominant triggering factor in influencing the overall climate fabric of the planet.

Introduction 
Chapter 16, “Global Warming and Food Security” delves into the intricate relationship between global warming and food security. The chapter opens by defining the multifaceted concept of food security, which includes availability, access, utilization, and stability. It emphasizes the critical importance of these components in ensuring a stable and reliable food supply. The chapter then explores various challenges to food security, highlighting the impact of rapid population growth, climate change, land and water scarcity, poverty, inequality, and conflicts. It underscores how these challenges are compounded by global warming, which exacerbates environmental stressors such as rising temperatures, altered weather patterns, and extreme weather events. The implications for agriculture are profound, affecting crop yields, livestock health, and overall food production. The section on the causes and consequences of global warming outlines key phenomena such as risi ng temperatures, changing weather patterns, melting glaciers, and ocean acidification. It illustrates how these factors disrupt agricultural systems and food distribution networks, leading to increased food insecurity. To address these issues, the chapter discusses various strategies for enhancing food security in a changing climate. These include adopting climate-smart agricultural practices, diversifying crop and livestock systems, developing climateresilient crop varieties, and implementing efficient water management strategies. It also highlights the importance of policy and institutional interventions, supportive measures for smallholder farmers, and research and development initiatives. The chapter concludes with a discussion on the need for collaboration and partnerships among various stakeholders, including governments, international organizations, and the private sector, to effectively address the dual challenges of global warming and food security. Global warming, a consequence of human-induced climate change, has emerged as one of the most pressing challenges of our time. As the Earth’s average temperature continues to rise, it brings about far-reaching impacts that extend to various sectors, including food and agriculture. The intricate relationship between global warming and agriculture is of paramount importance, as agricultural systems are both vulnerable to climate change and significant contributors to greenhouse gas emissions. Understanding the impacts of global warming on

11.1 Global Warming

Definition : Global warming is defined as an increase in the earth’s temperature due to the use of fossil fuels and other industrial processes leading to a build-up of green house gases (CO2, methane, ozone, nitrous oxide, and chlorofluorocarbons) in the atmosphere.

11.2 Who Coined the Term Global Warming?

The principle of global warming was first put fourth by S. Arrhenius in his paper on “the influence of carbonic acid in the air upon the temperature of the ground” in 1869. This concept gained ground in the late 1980s and early 1990s when it was found that the earth’s temperature had warmed over the past century, because of increased carbon dioxide emission.

1.1. Background Introduction

We live in a world with “throw-away” societies that are involved in a pattern of consuming packaged products that don’t even last past a single use or even a year and discarding the waste. This lifestyle generating waste is negatively impacting public health, environment and imposing socio-economic problems on us. The waste is continuously consuming our land, resources, and energy for storage, management, treatment, and disposal. Solid waste was an urban issue initially but has reached every corner nowadays. 

The weather parameters that may occur outside India will also play a dominant role on weather conditions in India. Such weather parameters are called as global weather parameters and were found to play very important role on weather even in most parts of the world. During normal conditions in the Pacific Ocean, trade winds blow west along the equator, taking warm water from South America towards Asia. To replace that warm water, cold water rises from the depths-a process called upwelling. These global parameters are popularly known as El Ni?o, La Ni?a, Southern Oscillation, and ENSO (combination of El Ni?o and Southern Oscillation).

Building upon the foundation laid in earlier chapters, perhaps exploring local weather dynamics and regional climate patterns, the present chapter “Global Weather Parameters and Teleconnections,” takes a significant step back to examine the Earth’s weather systems on a truly planetary scale. Here, we shift our focus to the fundamental forces and patterns that orchestrate the global climate ballet. We will delve into the key global weather parameters – think of these as the vital signs of our planet’s atmosphere – such as the overall distribution of temperature across latitudes and altitudes, the major global pressure belts that drive air movement, and the resulting large-scale wind systems that circulate heat and moisture around the globe. These parameters, born from the interplay of solar radiation, the Earth’s spherical shape, and its continuous rotation, are the primary drivers of our planet’s diverse climates. Beyond these fundamental parameters, this chapter will illuminate the fascinating world of teleconnections. Imagine the atmosphere and oceans as an intricate network, where events in one distant region can have a ripple effect on weather patterns thousands of kilometers away. Teleconnections represent these long-range linkages, acting as the “threads” that connect seemingly disparate weather phenomena. We will explore prominent examples like the El Niño- Southern Oscillation (ENSO), which has profound impacts on rainfall and temperature across the Pacific and well beyond, including potential influences on the Indian monsoon – a topic likely of particular interest given your previous research. Similarly, we will examine phenomena such as the North Atlantic Oscillation (NAO), influencing weather across Europe and North America, and the Madden-Julian Oscillation (MJO), a traveling wave of thunderstorms in the tropics that can affect global circulation. For those interested in agricultural meteorology, the understanding of global weather parameters and teleconnections is paramount. These largescale patterns and their interconnections play a critical role in shaping regional climate variability, influencing the onset and intensity of droughts and floods – events you’ve extensively researched – and impacting crop yields and water availability. By grasping these global drivers, we can enhance our ability to forecast seasonal weather patterns, anticipate potential climate-related risks to agriculture, and develop more informed strategies for long-term agricultural planning and adaptation in a changing world. This chapter aims to provide you

Transgenic varieties combine genes from totally unrelated species. For example, we can now transfer genes for salinity tolerance to rice from mangroves. The recombinant DNA technology is part of the evolution of genetics starting with the rediscovery of Mendel’s Laws of Inheritance in 1900. In the early part of the twentieth century, various techniques like irradiation, use of chemical mutagens and doubling of chromosomes through colchicine treatment were adopted to develop novel genetic combinations.  Today such gene transfer can be done with both precision and ease through recombinant DNA technology. Both molecular marker-assisted breeding and gene transfer now play a very important role in developing genetic combinations to meet the challenges rising from biotic (i.e., pest and diseases) and abiotic (i.e., drought, flood, sea level rise, etc.) stresses. They will gain further importance in the emerging era of climate change. Varieties developed by marker-assisted selection are also eligible for certification under the protocol for products produced through organic farming.

Goat is the 1st domesticated animal in the ancient age and has been considered to be the Poor Man’s Cow Goat’s meat is lean & has low fat and the demand for goat’s meat is increasing, with rising prices. Goats usually give birth to twins & triplets. Goat is a multi functional animal and plays a significant role in the economy and nutrition of landless, small and marginal farmers in the country. Goat rearing is an enterprise which has been practiced by a large section of population in rural areas. It can efficiently survive on available shrubs and trees in adverse harsh environment in low fertility lands where no other crop can be grown. In pastoral and agricultural subsistence societies in India, goats are kept as a source of additional income for their meat, hair fiber, and dairy, or as a pet. Goats are also used in ceremonial feastings and for the payment of social dues. According to FAO (2008) goat milk production in India were 4 million metric tons, Bangladesh 2.16 million metric tons and the Sudan 1.47 million metric tons over much of the world. Goats are among the main meat-producing animals in India, whose meat (chevon) is one of the choicest meats and has huge domestic demand (Shalander Kumar, 2007). Goat rearing is an enterprise which has been practiced by a large section of population in rural areas. Goats can efficiently survive on available shrubs and trees in adverse harsh environment in low fertility lands where no other crop can be grown. (Oberoi et al., 199I) reported that in variable cost, expenditure on labour was the major component of cost and was 81% under goat farming.

The increasing awareness of the deleterious effects of indiscriminate use of artificial inputs in agriculture such as chemical fertilizers and pesticides hasled to the adoption of organic farming as an alternative method for conventional farming. Farmers are adopting organic farming due to the advantages like,

• It is self-sustaining and socially and ecologically superior over the conventional farming.
• It makes use of cost effective management practices involving the use of farm inputs produced within the farm.
• It is less expensive.
• It is environment friendly as there is no pollution of soil and water.
• It enriches the soil and the local ecology.
• The produce is free of contamination from chemical residues has better taste, flavour and nutritional value.
• Seeds have more vitality and are good for successive generations.
• Growing markets for safe food

Agricultural practices in India remained virtually unchanged for over 2000 years till 1950-60. With technological advancement in medicine and improvement in health care services, population in India substantially increased in the post independence period. The result was that there was acute shortage of food during 1960s and India had to import massive quantities of wheat from USA to avert famine. Most of these food shipments were in the form of aid. It was then that Government of India realised the gravity of situation and invested heavily in agricultural research. Fortunately, during this period food research laboratories in the West developed hybrid varieties of seeds to suit various types of soil and climatic conditions. At the same time new types of fertilizers and pesticides were introduced which showed dramatic increase in the yield. The agricultural research laboratories in India were able to build on this research and provided extension services to adopt new agricultural techniques to farms in India. This led to dramatic improvement in agricultural production which was hailed as “Green Revolution”. Within two decades a country perennially deficient in food and subject to cyclic famines became a food surplus country in spite of the fact that there was a continuous rise in population which doubled in 30 years after independence. This trend continued into 1980’s when Government built huge buffer stocks of wheat and rice to meet the needs during lean production years.

However the momentum of Green Revolution could not be maintained and certain disturbing trends were noticed in 1990s. The growth rate in productivity declined from 2.99 per cent per annum to 1.21 per cent This was not because we had come to a technical plateau our yields of various products are still quite low as compared to those achieved by developed countries and even some of the developing countries.
