It is well recognized that sustainable management and sustainable livelihoods are inseparable. If neglected and if the present trends are not corrected in time, everyone’s future is threated. On the other hand, there is increasing recognition of living examples and demonstrated evidences of how the eco agricultural practices can help provide a solution to some of the major problems of today and tomorrow. Also, the main stream international agencies are emphasizing that agro-ecological approaches are the way forward. What the policy makers, farmers and people would like to know is How !it has been our experience that in most countries of the developing world the answer to ‘How’ of eco-agricultural is being demanded!

The Imperative for Regional Collaboration Climate change poses a transboundary threat that no single nation can address in isolation. In CMCs, rural populations, often dependent on agriculture and natural resources, are disproportionately vulnerable. For instance, Assam, India, faces rising temperatures and frequent floods, threatening 86% of its agriculture-dependent rural population. Similarly, Bangladesh, a climate change hotspot, grapples with salinization and cyclones that disrupt rural livelihoods. Regional collaboration offers a pathway to pool resources, share expertise, and develop scalable solutions. As the United Nations Economic and Social Commission for Western Asia highlights, collaborative action enhances food and water security through shared knowledge

There is no terminal of any kind of research, rather they presence a static snap of the gamut of ecological dynamics and functions.

Introduction 
Life’s unpredictability is a common thread that weaves through our experiences, prompting the use of various societal mechanisms to help us navigate the uncertainties we face (Lenhart, 2020). On a personal level, a typical strategy for managing this uncertainty includes utilizing financial instruments, commonly known as insurance (Ito & Kono, 2010). Today a diverse range of items is now eligible for insurance, encompassing aspects such as health, travel, and personal belongings, typically categorized as health, travel, and property insurance respectively. In India, the recognition of life insurance is prevalent, but with the increase in literacy and financial awareness, a growing number of individuals and families are starting to grasp the importance of health insurance (Kumar & Duggirala, 2021). Following this cause, the third goal of sustainable development that highlights the significance of ensuring and promoting healthy lives is worth mentioningtowards the effort of massification of the health insurance. By integrating finance, the third Sustainable Development Goal emphasizes a crucial initiative aimed at achieving universal health coverage for every citizen, which encompasses state health insurance for all individuals(Pauly, 1994). This initiative aims to equip citizens with the financial resilience needed to navigate an uncertain future, particularly concerning health-related challenges. In the context of health insurance frameworks, understanding the accessibility of initiatives aimed at the bottom of the pyramid is crucial for realizing universal health coverage towards achieving the SDGs’ (Pablos-Mendez, Cavanaugh, & Ly, 2016). The effectiveness of accessibility is intricately linked to the level of awareness that exists within the community. As the landscape of health insurance is ever-dynamic, understanding its intricacies will be crucial moving forward.For a thorough exploration, a researcher should have a wide-ranging grasp of the discipline, including theoretical, contextual, and methodological perspectives. Taking this into consideration, present chapter aims to explore a theoretical aspect of the review through a bibliometric analysis (Faruk, Rahman, Heliyon, & 2021, n.d.) of the literature spanning from 1984 to 2024 (Lebek, Uffen, Neumann, Hohler, & Breitner, 2014). This theoretical perspective will guide us in exploring how to reflect on the answers effectively. Theories illustrate methods for examining and establishing a structure for comprehending occurrences (Mahajan, n.d.). Furthermore, the theory clarifies how phenomena connect with the practical world, providing a distinct path and perspective for the researcher. This upcoming section will outline the reasoning behind this study, which entails performing a bibliometric analysis of the literature through the PRISMA Protocol (Moher et al., 2009), succeeded by a comprehensive text analysis of the chosen literature. The next section provides a concise overview of the theories explored within the realm of health insurance literature. This review adopts the PRISMA protocol (Moher et al., 2009) to scrutinize the articles to be included in the review. The protocol involves two phases of scrutinization, which consist of identification and screening. In the identification phase, I selected the Scopus register (Malanski, Dedieu, & Schiavi, 2021) and collected a database of 16797 articles. I gathered this database based on the “Article titles” criterion, including the keywords “Health Insurance” or “Health” and “Insurance” from 1984 to 2024, encompassing 50 years of literature. The year selection provides a timeline of the 50 years of academic scholarship related to the subset of health insurance as a research topic. After applying the language filter of English, duplication, and automation tools to this dataset, I were able to obtain 10961 articles for the subsequent screening stage. In this stage of screening, I have used the filter of subject area by selecting the subject area of Social Sciences; Business, Management, and Accounting; Decision Science; Economics, Econometrics, and Finance, which leads the collection of the 2580

This chapter focuses on key terms and their associated concepts that are crucial for effectively communicating the ideas of the study. It also establishes a theoretical orientation for the empirical investigation and provides guidance for selecting appropriate predictor variables that are relevant to the research.

The scholastic and theoretical exercise referred to in the statement related to the intellectual and academic process involved in conducting research. It involves delving into existing literature, theories, and concepts related to the research topic, as well as formulating new ideas and theories based on the researcher’s understanding and analysis.

One of the key outcomes of this exercise is the development of an operational definition. An operational definition is a clear and concise description of how a specific concept or variable will be measured or observed in the research study. It provides a framework for understanding and interpreting the data collected during the research process.

Furthermore, the pursuit of knowledge is an essential aspect of the research process. Researchers engage in a systematic exploration and investigation of the research topic, seeking to expand the existing knowledge base and contribute new insights to the field. This pursuit of knowledge involves critically analyzing existing theories, synthesizing information, and generating new ideas and theories through the research process. The theory that is developed as a result of this exercise is constructed in alignment with the set of objectives and research designs established at the beginning of the research project. The theory serves as a framework that guides the research process and helps to organize and interpret the data collected. It is important for the theory to be congruent with the research objectives to ensure the research study is focused and relevant to its intended goals.

3. Contemporary Crisis in Global Agriculture
Over the past century, bunch of initiatives have been taken and achieved worldwide in expediting human welfare. Societies have also changed to great extent as a result of quantum leaps in technology, rapid globalization, and innovations in agricultural production systems. Perhaps the world ‘free of fear and want’ envisioned at the foundation programme of the United Nations is still a far cry.
Similarly, much work left to be fulfilled the vision of the Food and Agriculture Organization of the United Nations (FAO) and to make ‘a world free of hunger and malnutrition and one in which food and agriculture contribute to improving the living standards of all, especially the poorest, in an economically, socially, and environmentally sustainable manner’.
Amidst great plenty, millions of people still face pervasive poverty, inequalities, joblessness, natural resource depletion, environmental degradation, displacement, migration, disease, and deprivation. Majority of humanity’s progress has reached at a significant cost to the environment. The impacts of climate change are already being felt, and if left unabated; definitely will intensify to a considerable extent in the years coming. Besides, population dynamics will radically change demographics over the decades ahead. Growth in the world’s population is projected to be concentrated in Africa and South Asia and in the biggest cities.
Then agricultural production has to maintain pace with those of rising population for atleast a sustainable world. Although, agricultural production more than tripled between the years of 1960 and 2015, where Green Revolution owes to robust crop production and a significant increment in the use of land, water and other natural resources for agricultural purposes. This period witnessed a remarkable progress in both of industrialization and globalization of food and agriculture. At the same time changes in the length of food supply chains took place as the physical distance from farm to plate has increased dramatically; the consumption pattern of processed, packaged, and prepared foods has changed simultaneously in everywhere though the most in rural communities.

The last century has witnessed a global change in agricultural practices. From high dependency on external input agriculture, the world is now shifting towards low external input sustainable agriculture (LEISA). The history of dustbowl devastation in 1930s in America has put agricultural practices, tillage in particular, to question (Friedrich et al., 2012). Traditionally, tillage was believed to be a primary farm operation for preparing a good seedbed, nutrient mobilization, weed management, moisture availability, crop residue incorporation (Hobbs et al., 2008), thereby improving the overall soil health with increased production (Farooq et al., 2011a). The dust bowl devastation of 1930s gave rise to the concept of protecting soil by reducing tillage operation and maintaining ground cover, popularized as conservation tillage (Friedrich et al., 2012). Economic and ecological sufferings caused by the disastrous droughts in USA during 1930s drove the shift towards conservation agriculture (CA) (Haggblade and Tembo, 2003).

3.1 Conceptual Framework

Aconceptual framework is an analytical tool that is used to get a comprehensive understanding of the study. It embodies the specific direction by which the research will have to be undertaken. It is generally constructed to provide the researcher the element ofattainable and researchable problems and ideas supported by methodology, design, prospective analysis and empirical conclusion. The conceptual framework is often called as the research paradigm.

The subject matter of the present research is Resilience and productivity of agriculture in different social-ecology: the farmers’ perception, status and interpretation. It is expected that the terminologies and concepts used to frame up the topic need to undergo brief explanation for the better understanding of its meaning.

Resilience: Resilience is about anticipating, planning and reducing disaster risk to effectively protect persons, communities and countries, their livelihoods, health, cultural heritage, socio-economic assets and ecosystems. The ideas of ‘bounce back’, ‘spring forward’ and ‘build back better’ are often used in the context of resilience.

Productivity: Productivity is commonly defined as a ratio between the output volume and the volume of inputs. It measures how efficiently production inputs, are being used in an economy to produce a given level of output.

Agriculture: The word agriculture derives from the Latin ager (field) and colo (cultivate) signifying, when combined, the Latin agricultura: field or land tillage. But the word has come to subsume a very wide spectrum of activities that are integral to agriculture and have their own descriptive terms, such as cultivation, domestication, horticulture, arboriculture, and vegeculture, as well as forms of livestock management such as mixed crop-livestock farming, pastoralism, and transhumance. The Oxford English Dictionary (1971) defines agriculture as “The science and art of cultivating the soil, including the allied pursuits of gathering in the crops and rearing livestock; tillage, husbandry, farming.”

A large number of genetic resources, species, and ecosystems are under severe threat. Many species have gone extinct and many more are being pushed towards extinction. Most of the ecosystems have also gone into what we can call functional extinction. The major factors becoming threats to biodiversity are anthropogenic. Human activities, in essence, are not benevolent for biodiversity to flourish in natural systems. Burgeoning human populations are the root cause of biodiversity destruction. Changing human lifestyles fed by a materialistic economy are further acting as catalysts for the ever-increasing human populations to destroy biodiversity evolved over millions of years amid terrestrial conditions favorable for the origin and prevalence of an astonishing variety of life forms on Earth.

There is hardly any threat to biodiversity due to natural factors except those inherent in the designs of natural evolution. A species at a certain point of time in its evolutionary history is destined to vanish, but the void in nature created due to this loss is filled by the evolution of new life forms. Not only the void is filled, the nature gradually goes on enriching itself 

Environmental contaminants are defined as substances introduced into the environment, either naturally or anthropogenically, that pose potentialharm to living organisms and ecosystems (Masindi and Muedi, 2018).These contaminants include a diverse range of pollutants, such as chemicalagents, biological contaminants and physical pollutants (Ahmed et al.,2021). Understanding these contaminants and their toxicity is of paramountimportance, given their profound implications on human health, biodiversityand the overall functioning of ecosystems (Samuel et al., 2023).Environmental contaminations are pervasive in nature and originated fromdiverse sources. Industrial activities are major contributors, releasing heavymetals, organic solvents, and particulate matter into air, water and soil(Williams, 2019). Similarly, agricultural practices contribute to contaminationthrough excessive use of fertilizers and pesticides, which often runoff intoaquatic systems, causing eutrophication and harming aquatic life (Zahoor and
Mushtaq, 2023). Urbanization and improper waste management have alsointensified the problem with plastics and emerging contaminants finding theirway into ecosystems (Singh et al., 2022). Even natural events like volcaniceruptions and forest fires contribute to environmental contamination, thoughtheir impacts are often localized and episodic compared to the persistent andwidespread pollution caused by human activities (Ernst, 2012).The study of environmental contaminants and their toxic effects is of vitalimportance for several reasons in today’s context of escalating global pollution(Hussain and Reza, 2023). First, it provides insights into the health risks posedto humans and wildlife (Pereira et al., 2015). Many contaminants, such as lead,mercury and polychlorinated biphenyls (PCBs), are known to have chronic andacute toxic effects on biological systems, affecting neurological, reproductivand immune functions (Priyadarshanee et al., 2022). These substances interactwith biological systems in complex ways, often leading to adverse outcomessuch as bioaccumulation, oxidative stress, endocrine disruption and ecologicalimbalances (Satkar et al., 2024). Heavy metals like lead and mercury are
known to accumulate in organisms and disrupt critical biological functions,while synthetic chemicals like bisphenol A (BPA) can interfere with hormonalsystems, resulting in reproductive and developmental issues (Pan et al., 2024).Such impacts underscore the need to understand how these substances interactwith living organisms, identify their exposure thresholds and mechanisms oftoxicity to formulate strategies for risk assessment and mitigation (Kumar andSingh, 2023).

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.

The success of an agroforestry system relies heavily on exploitation of the component interactions. In an ideal relationship, production of trees as well as crops or grasses in combination could be comparable to their sole performance. Agroforestry could be even more advantageous if the production of associated components is increased due to influence of trees. This is possible because trees are capable of improving productivity of soil in many ways. A large number of trees are known to fix nitrogen symbiotically. Nevertheless, instances of crop inhibition in association of trees are not uncommon. Such inhibitions are primarily caused by shade effect as well as competition for below-ground resources such as nutrients and water. In some cases inhibitory effect may also result from allelochemicals secreted by some of the tree species.

This chapter introduces tree improvement approaches aimed at developing forest species with enhanced resistance to biotic and abiotic stresses. It examines the challenges posed by climate change and discusses conventional and modern tree breeding techniques. The chapter further explores climate-smart tree improvement, resistance to pests and diseases, and tolerance to environmental stresses such as drought, heat, salinity, and other changing climatic conditions. By integrating breeding strategies with modern technologies and climate-resilience objectives, the chapter emphasizes the development of improved forest trees capable of maintaining growth, productivity, survival, and ecosystem functions under changing environmental conditions.

Tropical root and tuber crops are the third important group of food crops after cereals and pulses. Tuber crops hold a premier position among food crops in the tropical and subtropical regions of the world. These crops are rich in starch and calories and have great potential in meeting the food and energy needs.  More than 840 million people do not have enough food to meet their basic daily energy needs. Far more - an estimated 3 billion - suffer the insidious effects of micronutrient deficiencies leading to hidden hunger. Apart from its popular use as food, tubers also find an important space in cattle feed and agro industries sector.Tropical tuber crops possess high photosynthetic ability coupled with the capacity to yield under marginal lands, adverse biotic and abiotic stress etc (Ravindran et al., 2008).

Introduction

On 26^th December 2004, the Indian coastline experienced the most devastating tsunami in recorded history. The tsunami was triggered by an earthquake of magnitude Mw 9.3 at 3.316ºN, 95.854°E off the coast of Sumatra in the Indonesian Archipelago at 06:29 hrs making it the most powerful in the world in the last 40 years. In recent years increasing the vulnerability to natural disasters of developing countries is a major reason for concern. The potential loss of human lives and property due to natural hazards is very high in the urban areas of these countries. The Information obtained from conventional tsunami hazard maps does not always provide sufficient data for users .needs. The difficulty in presenting more significant information on tsunami hazard maps in conventional paper format is due to the limited available physical space of that format. Printing more information on such paper maps tends to confuse rather than provide more needed information to users. Furthermore, these kinds of maps provide little opportunity for users to ask for additional information, to determine the relationships between different kinds of information and important quantitative analyses. Furthermore, Tsunami hazards have important temporal attributes. Presenting these attributes on the map; e.g. the sequence of volcanic eruptions in a region or the frequency of tsumani in a particular area during a particular period of time is very difficult.

The phenomenon we call tsunami is a series of large waves of extremely long wavelength and period usually generated by a violent, impulsive undersea disturbance or activity near the coast or in the ocean. A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water.  Tsunami are sometimes called “seismic sea waves”, although, as we will see, they can be generated by mechanisms other than earthquakes.  Tsunami have also been called “tidal waves”, but this term should not be used because they are not in any way related to the tides of the Earth.  Because tsunami occur suddenly, often without warning, they are extremely dangerous to coastal communities.

Abstract

The UAE Space Reconnaissance Center (SRC) is accounted as a major national and regional source of up-to-date geospatial data, with direct reception of IKONOS, IRS and KOMPSAT satellite imagery as well as access to some other satellite and aerial imagery resources; an activity which covers the whole Middle East region. The main concern in monitoring the environment of UAE and surrounding countries is the desertification process, the monitoring of which requires careful watching of the sand movement and some other relevant features.

This paper throws light on the role of various types of satellite images in monitoring desertification, by utilization of IKONOS, IRS Pan and Landsat TM images covering part of Liwa and Alain areas, representing the two main dune regimes; Liwa and Manadir, which constitutes the northeastern edge of the Empty Quarter sand sea.

The availability of high resolution images makes it possible to detect the yearly or even seasonal sand movements, being controlled by the prevailing wind conditions and distance from the main sand source. The results clarify that movements of up to 25m was encountered at some small sand dunes and about 10m for larger sand dunes, towards the SSE and SSW in Liwa area. In Rimah area a movement of up to 30m was noticed at a small sand dune towards the ENE and about 12m shift in the hinge of a larger sand dune towards the NW. Temporary or permanent ? movement of thin sand sheets can reach 100’s of meters, was easily detected on Landsat images; ~ 25km NE of Alain city. The 5m panchromatic images, on the other hand, helped in tracing sand movements measured in few 10’s of meters, and interpretability of such images was enhanced by merging them with Landsat imagery.

The relentless march of urbanization, coupled with the growing uncertainties of a changing climate, casts a long shadow over the water security of our cities. Unlike their rural counterparts, urban areas face a distinct and often amplified set of challenges when drought strikes. The intricate web of municipal water supply, the concentrated demands of industry and commerce, and the sheer density of population render urban centers particularly vulnerable to the cascading impacts of water scarcity. When the taps run dry or restrictions tighten, the repercussions extend far beyond parched lawns and wilted gardens, impacting public health, economic stability, and the very fabric of urban life This chapter serves as an entry point into the critical field of urban drought management. We will delve into the unique characteristics that distinguish urban droughts from their rural counterparts, highlighting the interconnectedness of water systems and the amplified socioeconomic consequences within city limits. We will explore the increasing frequency and intensity of these events, driven by both natural climate variability and

Normally we associate our agriculture and food supply with farms and villages. The new trends of greener cities and urban and peri urban horticulture (UPH) are emerging very fast. Towns and cities in the world’s developing countries are growing at great speed. Ten years ago, an estimated 40 percent of the developing world’s population or 2 billion people lived in urban areas. Since then, their numbers have expanded twice as fast as total population growth, to more than 2.5 billion. By 2025, more than half the developing world’s population of 3.5 billion will be urban. Again most of the world’s fastest growing cities are in Asia and Africa with young population.

Trees are major capital assets in cities Just as streets, sidewalks, public buildings and recreational facilities are a part of a community’s infrastructure, so are publicly owned trees. Trees — and, collectively, the urban forest — are important assets that require care and maintenance the same as other public property. Trees are on the job 24 hours every day working for all of us to improve our environment and quality of life. Urban forest provides many environmental benefits to our community. Aside from the obvious aesthetic benefits, trees within our urban forest improve our air, protect our water, save energy, and improve economic sustainability.

In other words, since most trees have been planted much of the tree cover is in urban areas as opposed to “natural lands”. Therefore, estimated pollutant uptake rates are higher for residential compared to natural or unmanaged lands. Possible management implications of these estimates are that air pollutant uptake benefits from tree planting may be optimized by planting in areas where air pollutant concentrations are elevated and where relatively high planting densities can be achieved thereby enhancing the health of urban dwellers.

Abstract

The desert environment is one of the most challenging environments for human habitation. Inhabitants have to deal with climatic factors such as high temperature, sandstorms, flash floods and lack of water due to low rainfall. The people of Saudi Arabian desert had developed various traditional adaptation approaches such as living in tents, wearing head dresses, settling close to source of water, using camel for transportation, irrigation farming and traditional land management (hema). In recent times, modern technologies for air conditioning, transportation and housing have replaced the traditional adaptation methods especially in the cities. The modern technologies have reduced the challenges faced by the traditional society but has thrown up new challenges to sustainability. The new issues include urban flooding, depletion of underground water, high energy demand and consumption and loss of natural habitat to urbanization. This chapter reviews the traditional and the modern adaptation techniques in Saudi Arabia especially in the urban areas. It examines the implication of the changes for urban sustainability and explores different approaches for reducing the negative impacts. The chapter also dwells on the role of geospatial techniques in adapting to the desert environment.
