The Science of Ocean Waves: Ripples, Tsunamis, and Stormy Seas
by J. B. ZirkerAn unparalleled introduction to the amazing world of ocean waves.Outstanding Academic Title, Choice"Powerful ocean waves fascinate the public, and they have made a lot of news lately." With that indisputable observation, scientist J. B. Zirker takes off on a whirlwind tour of the world of waves—from the "ordinary" waves that constantly churn the sea to the rogues or freaks that can rise up seemingly from nowhere to heights of 20 meters or more... and everything in between.Addressing questions most ocean visitors have had and offering new ones for our consideration, The Science of Ocean Waves explains in accessible language how waves are formed, how they move, how they become huge and destructive, and how they're being studied now for clues that will help us plan for the future.Devoting chapters to wind, tides, currents, breakers, tsunamis, forecasting, renewable energy, and El Niño—as well as discussing the gentler properties of ocean waves which inspire us and offer opportunities for relaxation and recreation—Zirker explores the physical factors that create waves.Drawing on some of the recent storms that have devastated entire regions—such as Hurricane Katrina, the tsunami launched by the 2004 Sumatran earthquake, and the great tsunami that crushed the shore of Japan in 2011—Zirker explains the forces that cause these monster waves and reveals the toll they take on human lives.Enhanced by dozens of illustrations and a comprehensive glossary, The Science of Ocean Waves will fascinate anyone curious about the science behind the headlines.Praise for J. B. Zirker"Scientists know their stuff but are rarely good storytellers, whereas good storytellers rarely possess the necessary sweeping command of a scientific discipline. Zirker is that rare animal who can both communicate the most demanding technical detail and make it accessible."—New Scientist

Environmental Risk Modelling in Banking (Routledge International Studies in Money and Banking)
by Magdalena ZiołoEnvironmental risk directly affects the financial stability of banks since they bear the financial consequences of the loss of liquidity of the entities to which they lend and of the financial penalties imposed resulting from the failure to comply with regulations and for actions taken that are harmful to the natural environment. This book explores the impact of environmental risk on the banking sector and analyzes strategies to mitigate this risk with a special emphasis on the role of modelling. It argues that environmental risk modelling allows banks to estimate the patterns and consequences of environmental risk on their operations, and to take measures within the context of asset and liability management to minimize the likelihood of losses. An important role here is played by the environmental risk modelling methodology as well as the software and mathematical and econometric models used. It examines banks’ responses to macroprudential risk, particularly from the point of view of their adaptation strategies; the mechanisms of its spread; risk management and modelling; and sustainable business models. It introduces the basic concepts, definitions, and regulations concerning this type of risk, within the context of its influence on the banking industry. The book is primarily based on a quantitative and qualitative approach and proposes the delivery of a new methodology of environmental risk management and modelling in the banking sector. As such, it will appeal to researchers, scholars, and students of environmental economics, finance and banking, sociology, law, and political sciences.
Fostering Sustainable Business Models through Financial Markets (Strategies for Sustainability)
by Magdalena Ziolo Elena Escrig-Olmedo Rodrigo LozanoThe aim of this volume is to foster more sustainable business models through financial markets. To that end, it is necessary to know the main global challenges facing financial markets and their impact on creating sustainable value in business models of enterprises in the context of sustainable adaptation. The book focuses on assessing the decision criteria adopted by financial markets in the process of transaction risk valuation, in terms of the presence of Environmental, Social, and Governance (ESG) criteria, and by assessing the impact of including these criteria in the risk assessment process by financial markets in business decisions, leading as a consequence to building new value in the form of a sustainable business model. The book presents global ESG risks facing the financial markets, and discusses how ESG risks are managed and monitored, and how financial markets can measure and operationalize extra-financial risks in its assessment process. The book also analyses ESG risk implications and influences on company behavior, and the actions that companies should take considering the ESG assessment requirements of financial markets. Finally, it provides a comprehensive, structured, and systematic view of how financial markets and companies should adapt and improve their business models. The book provides unique challenges for investors, companies, financial markets, and for our society as a whole, advancing traditional risk management approaches to address global risks.
Finance and Sustainable Development: Designing Sustainable Financial Systems (Routledge International Studies in Money and Banking)
by Magdalena ZioloThere are many studies confirming the relationship between financial systems and economic development, but there are few which examine the degree to which financial systems a) impact the quality of information, b) influence sound corporate governance, c) ensure effective mechanisms of risk management, d) mobilize savings and f) facilitate trade. In the context of sustainability, there should also be a line of inquiry into how a particular financial system influences the assurance and implementation of sustainable development principles and goals. This book delivers a methodological approach to designing and assessing sustainable financial systems. It provides an original contribution by prioritizing ESG factors in the decision-making process of financial institutions and identifying their impact on sustainable financial systems. The author argues that to achieve financial stability, it is necessary to have in place mechanisms designed to prevent financial problems from becoming systemic and/or threatening the stability of the financial and economic system, while maintaining (or not undermining) the economy’s ability to sustain growth and perform its other functions. The book primarily takes a simulation and experimental approach. It is the first book to take such a comprehensive look at sustainable financial systems as opposed to sustainable finance in general. It will appeal to academics, students and researchers in the fields of economics, finance and banking, business, management and political and social sciences.
Introduction to Controlled-Source Electromagnetic Methods: Detecting Subsurface Fluids
by Anton Ziolkowski Evert SlobThis volume describes how controlled-source electromagnetic (CSEM) methods are used to determine the electrical conductivity and hydrocarbon content of the upper few kilometres of the Earth, on land and at sea. The authors show how the signal-to-noise ratio of the measured data may be maximised via suitable choice of acquisition and processing parameters and selection of subsequent data analysis procedures. Complete impulse responses for every electric and magnetic source and receiver configuration are derived, providing a guide to the expected response for real data. 1-D, 2-D and 3-D modelling and inversion procedures for recovery of Earth conductivity are presented, emphasising the importance of updating model parameters using complementary geophysical data and rock physics relations. Requiring no specialist prior knowledge of electromagnetic theory, and providing a step-by-step guide through the necessary mathematics, this book provides an accessible introduction for advanced students, researchers and industry practitioners in exploration geoscience and petroleum engineering.

Regenerating Cities: Reviving Places and Planet (Cities and Nature)
by Maria Elena Zingoni de BaroThis book sets out the discussion on how cities can contribute solutions to some of the challenges the urbanised world is facing, such as the pressure of growing populations, mitigation of effects of, and adaptation to globally changing environmental, climate and public health conditions. Presenting a detailed explanation of the causes behind the current state of modern cities, the book advocates for a paradigm shift to improve the quality of life of ever-increasing urban inhabitants whilst nourishing the natural systems that sustain human and non-human life in the planet. Recognising the precious role that nature plays in the functioning of cities, it delves into the study of biophilic design and regenerative development. The book argues that these social-ecological design approaches can act as catalysts to develop conditions in urban settings that are beneficial for natural and human systems to thrive and flourish, both in ecosystem services and social-cultural systems. This is particularly relevant for the design of new quality precincts or the regeneration of degraded urban spaces to promote health, wellbeing and urban resilience. A framework is proposed to guide the process of thinking about, designing and building healthier, more liveable and resilient urban environments that raise the quality of life in cities. The method can be used by researchers, practitioners -urban designers, urban planners, architects and landscape architects- interested in developing their work within a social-ecological perspective. It can also be used by local governments and agencies to underpin policy making, and by educational institutions to prepare graduates with necessary skills to respond to current and future built environment challenges.

Aluminum Upcycled: Sustainable Design in Historical Perspective (Johns Hopkins Studies in the History of Technology)
by Carl A. ZimringTracing the benefits—and limitations—of repurposing aluminum.Besides being the right thing to do for Mother Earth, recycling can also make money—particularly when it comes to upcycling, a zero waste practice where discarded materials are fashioned into goods of greater economic or cultural value. In Upcycling Aluminum, Carl A. Zimring explores how the metal’s abundance after World War II—coupled with the significant economic and environmental costs of smelting it from bauxite ore—led to the industrial production of valuable durable goods from salvaged aluminum. Beginning in 1886 with the discovery of how to mass produce aluminum, the book examines the essential part the metal played in early aviation and the world wars, as well as the troubling expansion of aluminum as a material of mass disposal. Recognizing that scrap aluminum was as good as virgin material and much more affordable than newly engineered metal, designers in the postwar era used aluminum to manufacture highly prized artifacts. Zimring takes us on a tour of post-1940s design, examining the use of aluminum in cars, trucks, airplanes, furniture, and musical instruments from 1945 to 2015. By viewing upcycling through the lens of one material, Zimring deepens our understanding of the history of recycling in industrial society. He also provides a historical perspective on contemporary sustainable design practices. Along the way, he challenges common assumptions about upcycling’s merits and adds a new dimension to recycling as a form of environmental absolution for the waste-related sins of the modern world. Raising fascinating questions of consumption, environment, and desire, Upcycling Aluminum is for anyone interested in industrial and environmental history, discard studies, engineering, product design, music history, or antiques.
The Economy of Green Cities: A World Compendium on the Green Urban Economy

Green cities are an imperative solution, not only in meeting global environmental challenges but also in helping to ensure socio-economic prosperity at the local level.
Metropolitan Regions, Planning and Governance
by Karsten Zimmermann Daniel Galland John HarrisonThe aim of this book is to investigate contemporary processes of metropolitan change and approaches to planning and governing metropolitan regions. To do so, it focuses on four central tenets of metropolitan change in terms of planning and governance: institutional approaches, policy mobilities, spatial imaginaries, and planning styles. The book’s main contribution lies in providing readers with a new conceptual and analytical framework for researching contemporary dynamics in metropolitan regions. It will chiefly benefit researchers and students in planning, urban studies, policy and governance studies, especially those interested in metropolitan regions.The relentless pace of urban change in globalization poses fundamental questions about how to best plan and govern 21st-century metropolitan regions. The problem for metropolitan regions—especially for those with policy and decision-making responsibilities—is a growing recognition that these spaces are typically reliant on inadequate urban-economic infrastructure and fragmented planning and governance arrangements. Moreover, as the demand for more ‘appropriate’—i.e., more flexible, networked and smart—forms of planning and governance increases, new expressions of territorial cooperation and conflict are emerging around issues and agendas of (de-)growth, infrastructure expansion, and the collective provision of services.
Governance and City Regions: Policy and Planning in Europe (Regions and Cities)
by Karsten Zimmermann Patricia FeiertagCity-regions are areas where the daily journeys for work, shopping and leisure frequently cross administrative boundaries. They are seen as engines of the national economy, but are also facing congestion and disparities. Thus, all over the world, governments attempt to increase problem-solving capacities in city-regions by institutional reform and a shift of functions. This book analyses the recent reforms and changes in the governance of city-regions in France, Germany and Italy. It covers themes such as the impact of austerity measures, territorial development, planning and state modernisation. The authors provide a systematic cross-country perspective on two levels, between six city-regions and between the national policy frameworks in these three countries. They use a solid comparative framework, which refers to the four dimensions functions, institutions and governance, ideas and space. They describe the course of the reforms, the motivations and the results, and consequently, they question the widespread metropolitan fever or resurgence of city-regions and provide a better understanding of recent changes in city-regional governance in Europe. The primary readership will be researchers and master students in planning, urban studies, urban geography, political science and governance studies, especially those interested in metropolitan regions and / or decentralisation. Due to the uniqueness of the work, the book will be of particular interest to scholars working on the comparative European dimension of territorial governance and planning.

Contesting Earth's Future: Radical Ecology and Postmodernity
by Michael E. ZimmermanRadical ecology typically brings to mind media images of ecological activists standing before loggers' saws, staging anti-nuclear marches, and confronting polluters on the high seas. Yet for more than twenty years, the activities of organizations such as the Greens and Earth First! have been influenced by a diverse, less-publicized group of radical ecological philosophers. It is their work—the philosophical underpinnings of the radical ecological movement—that is the subject of Contesting Earth's Future.The book offers a much-needed, balanced appraisal of radical ecology's principles, goals, and limitations. Michael Zimmerman critically examines the movement's three major branches—deep ecology, social ecology, and ecofeminism. He also situates radical ecology within the complex cultural and political terrain of the late twentieth century, showing its relation to Martin Heidegger's anti-technological thought, 1960s counterculturalism, and contemporary theories of poststructuralism and postmodernity.An early and influential ecological thinker, Zimmerman is uniquely qualified to provide a broad overview of radical environmentalism and delineate its various schools of thought. He clearly describes their defining arguments and internecine disputes, among them the charge that deep ecology is an anti-modern, proto-fascist ideology. Reflecting both the movement's promise and its dangers, this book is essential reading for all those concerned with the worldwide ecological crisis.
Changing Fortunes: Biodiversity and Peasant Livelihood in the Peruvian Andes (California Studies in Critical Human Geography #1)
by Karl S. ZimmererTwo of the world's most pressing needs—biodiversity conservation and agricultural development in the Third World—are addressed in Karl S. Zimmerer's multidisciplinary investigation in geography. Zimmerer challenges current opinion by showing that the world-renowned diversity of crops grown in the Andes may not be as hopelessly endangered as is widely believed. He uses the lengthy history of small-scale farming by Indians in Peru, including contemporary practices and attitudes, to shed light on prospects for the future. During prolonged fieldwork among Peru's Quechua peasants and villagers in the mountains near Cuzco, Zimmerer found convincing evidence that much of the region's biodiversity is being skillfully conserved on a de facto basis, as has been true during centuries of tumultuous agrarian transitions.Diversity occurs unevenly, however, because of the inability of poorer Quechua farmers to plant the same variety as their well-off neighbors and because land use pressures differ in different locations. Social, political, and economic upheavals have accentuated the unevenness, and Zimmerer's geographical findings are all the more important as a result. Diversity is indeed at serious risk, but not necessarily for the same reasons that have been cited by others. The originality of this study is in its correlation of ecological conservation, ethnic expression, and economic development.
Political Ecology
by Karl Zimmerer Thomas J. BassettThis volume offers a unique, integrative perspective on the political and ecological processes shaping landscapes and resource use across the global North and South. Twelve carefully selected case studies demonstrate how contemporary geographical theories and methods can contribute to understanding key environment-and-development issues and working toward effective policies. Topics addressed include water and biodiversity resources, urban and national resource planning, scientific concepts of resource management, and ideas of nature and conservation in the context of globalization. Giving particular attention to evolving conceptions of nature-society interaction and geographical scale, an introduction and conclusion by the editors provide a clear analytical focus for the volume and summarize important developments and debates in the field.
