Introduction

A system is a simplified version of reality and is defined as a collection of interrelated parts that work together. Most systems share certain common characteristics. These common characteristics include the following:
Systems have a structure that is defined by its parts and processes. Systems are generalizations of reality.
Systems tend to function in the same way as nature. This involves inputs getting changed in a process and realization of new outputs.
The various parts of a system have functional as well as structural relationships between each other.
Owing to the functional relationships that exist between the parts there is a flow and transfer of some type of energy and/or matter. In case of information systems there is a flow of information in the structure.
The parts that make up a system show certain degree of integration. In other words the parts work well together.

Abstract

The rapid development and integration of spatial technologies viz., Geographical Information System (GIS), Remote Sensing (RS) along with Global Positioning Systems (GPS) provide functional alternatives to revolutionize the conventional entomological approaches like surveillance, spatial/temporal distribution of insect populations, pest distribution mapping and predictive modeling. Application of these technologies for insect problems is well established in the fields of forest, range land, medical and agricultural entomology elsewhere. Nevertheless, in India its field relevance in agricultural entomology is still limited owing to lack of proven field prototype studies and collaborative efforts among stakeholders. It’s time to gain real momentum to integrate these progressive technologies to formulate sustainable integrated pest management programs.

Key words: GIS, Remote Sensing, Insect Populations, Field Applications

This chapter introduces the integration of Geographic Information Systems (GIS), remote sensing, and artificial intelligence (AI) for modern forest monitoring and management. It explains how remote sensing provides spatially continuous information, GIS functions as a spatial database and decision-support environment, and AI and machine learning enable prediction and pattern recognition. Applications include forest inventory, carbon estimation, biodiversity assessment, forest-fire detection, insect monitoring, and disturbance mapping. The chapter also examines GeoAI, smart forestry, emerging technologies, data challenges, and future opportunities such as cloud-based geospatial platforms and explainable AI.

impacts other speheres and that too on a distal place! This chapter explains how global warming affects remote places like highlands of Bhutan. Severe hot summers during the year 1994 led to excessive melting of glaciers in the higher Himalayas. The exceptional melting contributed enormous amount of melt water to the lake basins, which caused breach of the morainic dam and consequent enlargement of the outlet of the Luggye Tsho and the Tshopda Tsho, Bhutan. Floods followed the breach on October 7, 1994. These floods destabilized the slopes on either bank of the Pho Chhu near Tshopda Tsho outlet making them prone to landslides. The flash floods also eroded the left lateral moraine of the Raphstreng Tsho, which had disturbed the original angle of repose. The Raphstrcng area is also prone to ice avalanches, rock glaciers, surge of which can damage the rim and also cause spillover of water. Examination of geological, geomorphological, geotechnical, microclimatic and hydrographic information in and around the glacial lakes led to improved understanding of breach characteristics based on which mitigation measures were suggested and implemented in the years 1996-97. Since then the lakes have remained intact. From this case study and satisfactory performanceof mitigationmeasures suggest that similar integrated studies have to be conducted for thorough understanding of hazard prone areas based on which mitigation measures have to be implemented for successful reduction of impacts.

INTRODUCTION

The Lunana area, situated in the northern district of Gasa, is one of the most extensively glaciated terrains of Bhutan (Fig. 1). In response to the general global warming, these glaciers like those of other parts of the Himalaya are in a state of steady retreat, often leaving behind a chain of lakes. Though the glacial lakes endow scenic beauty, they also pose environmental hazards, due to frequent bursting of their morainic dams and consequent flash floods. The last lake-burst occurred on 7^th October 1994, leading to floods in the Pho Chhu River. Following floods, the Geological Survey of India in collaboration with the Royal Government of Bhutan, investigated the Lunana area to identify the causes and effects of the floods and suggest remedial measures. More than a decade had passed since the implementation of mitigation measures and there has been no such breach and flood despite continued Glacial Vetreat during to Global Warming. This chapter describes the characteristics of these glacial lakes, nature and results of the study and mitigation efforts.

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

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.

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

The growing demand for sustainable materials has encouraged the development of green composites based on bio-based polymers and renewable reinforcements.

Green business, is enterprise that has no negative impact on the global or local environment, community, society, or economy—a business that strives to meet the triple bottom line. Often, sustainable businesses have progressive environmental and human rights policies. In general, business is described as green if it matches the following four criteria:

1. It incorporates principles of sustainability into each of its business decisions.

2. It supplies environmentally friendly products or services that replace demand for non-green products and/or services.

3. It is greener than traditional competition.

4. It has made an enduring commitment to environmental principles in its business operations.

A sustainable business is any organization that participates in environmentally friendly or green activities to ensure that all processes, products, and manufacturing activities adequately address current environmental concerns while maintaining a profit. In other words, it is a business that “meets the needs of the present world without compromising the ability of the future generations to meet their own needs.” It is the process of assessing how to design products that will take advantage of the current environmental situation and how well a company’s products perform with renewable resources.

Green composites are emerging as promising alternatives to conventional synthetic composites in response to climate change, resource scarcity, environmental degradation, and increasing demand for sustainable materials. This chapter reviews the current landscape of green composites and examines the challenges associated with their broader adoption. It discusses technological innovations, smart sustainable materials, bio-based nanocomposites, hybrid systems, environmental and economic implications, and the relationship between green composites and sustainable development. Processing limitations, high costs, regulatory uncertainties, and commercialization challenges are considered alongside opportunities for technological advancement. Life-cycle assessment and supportive policies are important for evaluating environmental impacts and accelerating the transition toward circular and sustainable material systems.

Green energy can be classified as any form of energy resource that results in zero greenhouse gas emissions and zero toxic byproducts. These constitute the alternate source of energy such as Solar, Bio, Hydrogen, Wind, Water etc. Renewable Energy is energy that is not depleted or expen- ded. Previously the pressure to reduce CO2 emissions dictated the energy sourcing. With recent findings from experimental evidence, global warming may not be attributable to CO₂ emissions in relation to other over-weighing causes. However the pressures to develop renewable sources continue since the cost of Oil is increasing in many countries. It is desirable and a necessity to develop renewable non-toxic energy resources. The global economy and welfare of all earth depends on it even if CO₂ is not the cause of global warming (GW). There are some factors not in the control of even the most technologically advanced society. These are solar activity such as sun spots which have huge and tremendous influence on the Earth’s climate. However we should strive not to cause any undue imbalances in the proportion matter and composition of Earth’s atmosphere. Although CO2 is a small contributor to GW in comparison to H₂O, we still have responsibility to maintain the right balance of the gases in the atmosphere by not causing undue changes to the Carbon, Nitrogen and Oxygen cycles! We are far way off from a Oil-free technology. Most transportation is still petrol driven.

Introduction 
To fight climate change and lessen dependency on fossil fuels, the world urgently needs renewable and environmentally friendly energy sources. Hydrogen has become a promising energy carrier due to its versatility and capacity to generate energy from renewable resources without releasing greenhouse gases into the atmosphere. The world's demand for energy has been steadily increasing as a result of urbanization, economic expansion, and population rise. With an estimated 10 billion people on the earth by 2050, energy consumption is only expected to increase. Fossil fuels, which include oil, coal and gas have been widely used to generate energy and are predicted to do so at least until 2050 (see Fig.6.1) [1]. Figure 1. Global primary energy consumption is broken down by energy source [2, 3]. These fuels generate a large amount of greenhouse gases (GHGs) during combustion, especially carbon dioxide (CO2), which is connected to climate change and global warming. In addition, burning fossil fuels releases particulate matter (PM), sulfur oxides (SOx), nitrogen oxides (NOx), and other pollutants that are harmful for human health. In addition, the unequal distribution of fossil fuel supply has led to increased instability globally and worries about energy security. Numerous nations started making investments in energy from renewable sources as concerns about the environment and energy security have grown. Because they emit little to no greenhouse emissions, renewable energy resources like hydroelectricity, wind, and solar power contribute to lowering the energy industry's overall environmental impact (see Fig.6.2) [4].
