Man’s environment is pervaded by ionizing radiation of predominantly natural origin but now with an important contribution from anthropogenic activities. Exposure to ionizing radiation can have serious health implications, which is why it is of concern to us. This book brings together under one cover, the fundamentals of radiological protection, the techniques used for measuring radioactivity and radionuclides and the methods for modelling the dispersion of radionuclides in the environment. Information on radioactive decay, the interaction of ionizing radiation with matter and biological effects of radiation is provided in a form that enables the reader to quickly appreciate its importance to the environment and human health. Summaries of the effects of past releases, including the Chernobyl accident, are included as well as examples of applications of models to calculate and predict concentrations of radionuclides in our environment. This book is aimed at all those studying, at undergraduate and graduate levels, radioactivity in the environment and its impact on man. It will also serve as a handbook for workers in the fields of radiochemical analysis and environmental modelling and for scientists, consultants and environmental health and pollution officers who have to provide radiological data or information for legislative and related purposes.
This book has following unique features that distinguish it from other works from the same area: 1) Investigates the influence of fissure geometry on strength failure and crack evolution behaviour of real rock material; 2) Analyzes the effect of pre-experiment high-temperature treatment on fracture mechanical behaviour of rock material with a single fissure or two parallel fissures; 3) Compares quantitatively simulated results using discrete element modelling and experimental results of fracture mechanical behaviour of rock material with two fissures; 4) Constructs the relationship between crack evolution processes and acoustic emission distribution of pre-fissured rock material under entire deformation; and 5) Discusses the crack evolution mechanism of pre-fissured rock material with respect to different confining pressures. This book can become the reference for technicians in the field of geotechnical engineering, mining engineering and geology engineering. At the same time, this book can be regarded as a good reference for scientific researchers carrying out fissured rock mechanics and correlated specialties.

This work will appeal to a wide readership from technicians in the field of geotechnical engineering and engineering geology to scholars carrying out research in the rock mechanics.
Modern life is increasingly relying on digital technology, which in turn runs on mathematics. However, this underlying math is hidden from us. That is mostly a good thing since we do not want to be solving equations and calculating fractions just to get things done in our everyday business. But the mathematical details do matter for anyone who wants to understand how stuff works, or wishes to create something new in the jungle of apps and algorithms. This book takes a look at the mathematical models behind weather forecasting, climate change prediction, artificial intelligence, medical imaging and computer graphics. The reader is expected to have only a curious mind; technical math skills are not needed for enjoying this text.
Ever-increasing population growth has caused a proportional increased demand for water, and existing water sources are depleting day by day. Moreover, with the impact of climate change, the rates of rainfall in many regions have experienced a higher degree of variability. In many cities, government utilities have been struggling to maintain sufficient water for the residents and other users. The Handbook of Irrigation Hydrology and Management examines and analyzes irrigated ecosystems in which water storage, applications, or drainage volumes are artificially controlled in the landscape and the spatial domain of processes varies from micrometers to tens of kilometers, while the temporal domain spans from seconds to centuries. The continuum science of irrigation hydrology includes the surface, subsurface (unsaturated and groundwater systems), atmospheric, and plant subsystems. Further, the book includes coverage of environmental and economic impacts, water quality issues, water harvesting, satellite measurements for irrigation, and more. Features: Offers water-saving strategies to increase the judicious use of scarce water resources Presents strategies to maximize agricultural yield per unit of water used for different regions Compares irrigation methods to offset changing weather patterns and impacts of climate change
The Routledge Handbook of Law and the Anthropocene provides a critical survey into the function of law and governance during a time period when humans have power to impact the Earth system. The Anthropocene is a 'crisis of the earth system'. This book addresses its implications for law and legal thinking in the 21st century. Unpacking the challenges of the Anthropocene for advocates of ecological law and politics, this handbook pursues a range of approaches to the scientific fact of anthropocentrism, with contributions from lawyers, philosophers, geographers and environmental and political scientists. Rather than adopting a hubristic normativity, the contributors engage methods, concepts and legal instruments in a way that underscores the importance of humility and an expansive ethical worldview. Contributors to this volume are the leading scholars and future leaders in the field. Rather than upholding orthodoxy, the handbook also problematizes received wisdom and is grounded in the conviction that the ideas we have inherited from the Holocene must all be open to question. Engaging such issues as the Capitalocene, Gaia theory, the rights of nature, posthumanism, the commons, geoengineering and civil disobedience, this handbook will be of enormous interest to academics, students and others with interests in ecological law and the current environmental crisis.

Science Communication in a Crisis: An Insider’s Guide identifies the principal challenges that scientists face when communicating with different stakeholder groups and offers advice on how to navigate the maze of competing interests and deliver actionable science when the clock is ticking. If a scientist’s goal is to deliver content and expertise to the people who need it, then other stakeholder groups—the media, the government, industry—need to be considered as partners to collaborate with in order to solve problems. Written by established scientist Christopher Reddy, who has been on the front lines of several environmental crisis events, the book highlights ten specific challenges and reflects on mistakes made and lessons learned. Reddy’s aim is not to teach scientists how to ace an interview or craft a soundbite, rather, through exploring several high-profile case studies, including the North Cape oil spill, Deepwater Horizon, and the 2021 Sri Lanka shipping disaster, he presents a clear pathway to effective and collaborative communication. This book will be a great resource for junior and established scientists who want to make an impact, as well as students in courses such as environmental and science communication.

Also considers the submarine topography and geology around the islands, and ore deposits in relation to igneous act
Controlling the level of greenhouse gas in the atmosphere is a rapidly growing area of commercial activity. While debate continues both about the impact of greenhouse gas on climate and the role humans play in influencing its concentration, engineers are faced with less controversial questions of how to manage this uncertainty and how to control greenhouse gases at a minimum cost to society. This book gives a concise review of current knowledge required for engineers to develop strategies to help us manage and adapt to climate change. It has been developed from the author's graduate course in environmental engineering. It is written without technical jargon so as to be accessible to a wide range of students and policymakers who do not necessarily have scientific or engineering backgrounds. Appendices allow readers to calculate for themselves the impact of the various strategies, and the book contains student exercises and references for further reading.
Millions of lives and business have either been lost or significantly impacted by COVID-19. Yet, many are warning that climate change will be much more devastating over the coming decades. Reality is starting to set in. We are not going to achieve our global mitigation targets; we probably won’t even come close. Individuals faced with this reality react differently, from willful ignorance to anxiety and depression, all normal reactions. If you believe in science and understand the likelihood of our failure to meet our targets, you need to accept and plan for an unknown, challenging future. We may be individually powerless to stop climate change, but we certainly can act in ways that will help us better face the consequences. This book provides a structured approach to plan and prepare today for a world rocked by a turbulent climate.

The number of Earth observation satellites launched in recent years is growing exponentially, along with the datasets they gather from free-to-access and commercial providers. The second edition of Practical Handbook of Remote Sensing is updated with new explanations and practical examples using the Copernicus satellite data and new versions of the open-source software. A new chapter and new applications have also been added. Thoroughly revised, the handbook continues to be a practical "how-to" remote sensing guide for those who want to use the technology, understand what is available, how to access it, and answer questions about our planet, but do not necessarily want to become scientific experts.
This 2nd edition lays out an updated version of the general theory of light propagation and imaging through Earth's turbulent atmosphere initially developed in the late '70s and '80s, with additional applications in the areas of laser communications and high-energy laser beam propagation. New material includes a chapter providing a comprehensive mathematical tool set for precisely characterizing image formation with the anticipated Extremely Large Telescopes (ELTS), enabling a staggering range of star image shapes and sizes; existing chapters rewritten or modified so as to supplement the mathematics with clearer physical insight through written and graphical means; a history of the development of present-day understanding of light propagation and imaging through the atmosphere as represented by the general theory described. Beginning with the rudimentary, geometrical-optics based understanding of a century ago, it describes advances made in the 1960s, including the development of the 'Kolmogorov theory,' the deficiencies of which undermined its credibility, but not before it had done enormous damage, such as construction of a generation of underperforming 'light bucket' telescopes. The general theory requires no a priori turbulence assumptions. Instead, it provides means for calculating the turbulence properties directly from readily-measurable properties of star images.

This volume contains the papers presented at the International Workshop "Information Fusion and Geographic Information Systems" (IF&GIS'09) held in St. Petersburg, Russia in May 2009. The workshop was organized by the St. Petersburg Institute for Informatics and Automation of the Russian Academy of Sciences (SPIIRAS). The workshop continues a series organised biannually, and attracts academics and industrials from a wide range of disciplines including computer science, geography, statistics, mathematics, hydrography, geomorphology, and environmental sciences. The objective of this workshop is to provide a forum for innovative research oriented towards Geographic Information Science and tech- logies and Corporate Information Systems whose close association highlight novel theoretical and practical challenges. The papers selected by the International Program Committee cover a wide range of innovative areas including ontological and semantic approaches for the representation of geographical data, geographical data monitoring, situation management and forecast, to emerging applications oriented to the maritime environment, disaster management and security threats. While traditional topics of GIS conferences are well represented and still being advanced, several new domains appear and stress the need for the development of versatile monitoring systems and decision making systems. While GIS already have a de facto standard for geographical monitoring and analysis, the papers accepted in this volume also illustrate several novel directions of application whose objective is more closely oriented to process modeling and decision making, and where the nature of the objects represented is revisited using ontological and semantic approaches.

This work presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. With emphasis on methodology, understanding crop genetics, and applications to major crops, it covers a wide range of crops including row crops, fruits, vegetables, nuts and trees grown for timber and pulp.
This volume provides essential information on the origin and evolution of Greek rivers, as well as their ecological and anthropogenic characteristics. The topics covered include geomythology, biogeography, hydrology, hydrobiology, hydrogeochemistry, geological and biogeochemical processes, anthropogenic pressures and ecological impacts, water management - both in the antiquity and today - and river restoration. The book is divided into four parts, the first of which explores the importance of rivers for ancient Greek civilization and the natural processes affecting their evolution during the Holocene. In the second part, the hydrological, hydrochemical and biological features of Greek rivers and the unique biogeographical characteristics that form the basis for their high biodiversity and endemism are highlighted, while the third part comprehensively discusses the impacts of environmental pollution on the structure and function of Greek river ecosystems. In turn, the final part describes the current socio-economic factors in Greece that are affecting established water management practices, the application of ecohydrological approaches in restoring fragmented rivers, and the lessons learned from restoring aquatic ecosystems in general as a paradigm for understanding and minimizing anthropogenic impacts on water resources, at the Mediterranean scale. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.
