Adaptation to Climate Change: A Spatial Challenge
by Rob RoggemaAs it becomes clear that climate change is not easily within the boundaries of the 1990’s, society needs to be prepared and needs to anticipate future changes due to the uncertain changes in climate. So far, extensive research has been carried out on several issues including the coastal defence or shifting ecozones. However, the role spatial design and planning can play in adapting to climate change has not yet been focused on. This book illuminates the way adaptation to climate change is tackled in water management, ecology, coastal defence, the urban environment and energy. The question posed is how each sector can anticipate climate change by creating spatial designs and plans. The main message of this book is that spatial design and planning are a very useful tool in adapting to climate change. It offers an integral view on the issue, it is capable in dealing with uncertainties and it opens the way to creative and anticipative solutions. Dealing with adaptation to climate change requires a shift in mindset; from a technical rational way of thinking towards an integral proactive one. A new era in spatial design and planning looms on the horizon.
Adaptation and Mitigation Strategies for Climate Change
by Ai Hiramatsu Kensuke Fukushi Akimasa SumiIn recent decades there has been a growing awareness of how intricate the interactions are between human beings and the environment. Fortunately, progress has been made in understanding this relationship, and new technologies have been effective in addressing environmental problems. However belatedly, there has been an acknowledgment of the incompatibility of the world's finite resources with humankind's increasingly greater needs for them, and of how such a challenge demands broadened collaboration among engineers, social scientists, politicians and financial powers. Global agreement that the essential issues of the twenty-first century cannot be solved by any one discipline has led to the concept of sustainability. The transdisciplinary contributions selected for inclusion in this book address these concerns with an overview of the diverse fields of study related to sustainability. This collection of work is intended to pave the way for further collaboration among scientists and nations as well.
Adaptation and Evolution in Marine Environments, Volume 1: The Impacts of Global Change on Biodiversity (From Pole to Pole)
by Guido di Prisco and Cinzia VerdeThe poles undergo climate changes exceeding those in the rest of the world in terms of their speed and extent, and have a key role in modulating the climate of the Earth. Ecosystems adapted to polar environments are likely to become vulnerable to climate changes. Their responses allow us to analyse and foresee the impact of changes at lower latitudes. We need to increase our knowledge of the polar marine fauna of continental shelves, slopes and deep sea, as identifying the responses of species and communities is crucial to establishing efficient strategies against threats to biodiversity, using international and cross-disciplinary approaches. The IPY 2007-2009 was a scientific milestone. The outstanding contribution of Marine Biology is reflected in this volume and the next one on “Adaptation and Evolution in Marine Environments – The Impacts of Global Change on Biodiversity” from the series “From Pole to Pole”, making these volumes a unique and invaluable component of the scientific outcome of the IPY.
Adapt: How We Can Learn from Nature's Strangest Inventions
by Amina KhanNature's creations are more sophisticated and elegant than anything humans have created. Geckos can run upside down along ceilings. Termite mounds can stay cool in the desert without air conditioning. Adapt explores how we can harness such ideas through the ground-breaking new science of biomimicry - which looks to nature to solve pressing problems in engineering and science. From the depths of the oceans to the ice sheets of the Arctic, Amina Khan talks to the researchers at the forefront of this exciting new science, who are designing everything from wind turbines to military camouflage. An entertaining eulogy to the power of evolution, this captivating book is a must read for anyone with an interest in design, nature and technology.Khan leaves no stone unturned... Readers will leave this book with a buzzing excitement. - BBC Wildlife

Action Research for Sustainability: Social Imagination Between Citizens and Scientists
by Jonas EgmoseHow can action research further new research orientations towards sustainability? This book, empirically situated in the field of upstream public engagement, involving local residents, researchers and practitioners in bottom-up processes deliberating on urban sustainability, answers this question by analysing processes of social learning. The book addresses the need to move towards sustainability at societal level as a democratic challenge questioning the way we live on planet earth. By conceptualising sustain-ability as an immanent and emergent ability of ecological and social life, continuously to renew itself without eroding its own foundation of existence, it argues that since sustainability cannot be invented but only supported (or eroded) by science, we need to reframe science in the role of sustaining sustain-ability. Through analyses of a three year action research programme, aiming to provide local citizens with a greater say in the future of urban sustainability research, this book shows how action research can make important methodological contributions to processes of social learning between citizens and scientists by enabling free spaces in peoples everyday life and within academia, where aspects of un-sustainability can be addressed and new imaginations of more sustainable futures emerge.

Packed with adventure and heart, Across the Desert speaks to the resilience, hope, and strength within each of us.
Across the Country from Thonon to Trent: Rambles and Scrambles in Switzerland and the Tyrol
by Douglas FreshfieldThis is a true 'Boys' Own' adventure story of how three English schoolboys spent the summer of 1863 trekking through the Swiss and Italian Alps before conquering Mont Blanc. It is an utterly unique journal written by one of that party who would go on the become one of the great mountain and travel writers of the Victorian era and make a huge contribution to the Royal Geographic Society and the Alpine Club. His name was Douglas William Freshfield. Douglas William Freshfield was born on Sunday, 27 April 1845 in London, the only son of Henry Ray Freshfield and Jane Quinton Crawford. After being educated at Eton College and University College, Oxford, he followed his father into the legal profession and was called to the bar in 1870. One of the features of his privileged childhood was the opportunity to travel with his parents and enjoy long summer holidays abroad. At the age of eight he had his first experience of the Swiss Alps undertaking a journey from Basel to Chamonix. Eventually, in 1863, he was ready to undertake an Alpine adventure of his own planning. This volume, which he arranged to have printed privately in 1865 was his first work of mountain literature and also his rarest. It is his journal of that trek made from the southern shores of Lake Geneva, in the company of two schoolfriends, through the Swiss Alps and into northern Italy during the summer of 1863. Freshfield was only 18 when he made the trip, and in the narrative of the journal can be found the beginnings of the style and observational genius that was to serve him well over the course of his writing career. The reader is engaged at once with the three young men as they begin their adventure and is bowled along as an unseen travelling companion through the high routes and passes, the valleys and gorges until making the summit with them on Mont Blanc. It is an engaging and informative journal of how privileged young Englishmen once spent their leisure time and reveals a lifestyle long gone now but still worthy of reminiscence.

Acoustics of Wood (Springer Series in Wood Science)
by Voichita BucurConsiderable activity in the acoustics of wood has occurred since the first edition of this book in 1995. An informal survey of a number of the published articles and papers presented at international conferences revealed that the interest of the wood science community is continually increasing. In this context, I felt c- pelled to revise the text in accordance with newer findings and this prompted the addition in the present book of 159 new references added to the existing 850 in the first edition. As a result of the favorable comments upon the first edition, from students and colleagues, I have included a part on mathematical theory related to wave pro- gation in orthotropic solids in the general text, in order to enable the interested reader to follow the essentially physical aspects of the subject. A new chapter related to “acousto-ultrasonics” is introduced; Chapters 4, 5, 6, 8, 9, 10, 11, and 12 have been considerably expanded and a significant redistribution of the subject matter from the earlier edition has been made.
Ackerlandschaften: Nachhaltigkeit und Naturschutz auf ertragsschwachen Standorten
by Ulrich Hampicke Birgit Literski Wendelin WichtmannIn weiten Gebieten Mitteleuropas ist Ackerbau auf ertragsschwachen Standorten nur mit öffentlicher Förderung kostendeckend. Diese ist für die nähere Zukunft gesichert, langfristig aber ungewiss. Eine großflächige Aufgabe des Ackerbaus wäre aus zahlreichen Gründen problematisch. Ausgehend von einer historischen Betrachtung untersucht dieses Buch Perspektiven eines extensiven, multifunktionellen Ackerbaus, der Naturschutz und Erholungseignung in sein Zielbündel integriert. Anbautechnik, Fruchtfolgen sowie Wirkungen auf Bodenfruchtbarkeit, Wasserhaushalt und Artenvielfalt werden vorgestellt. Detailliert ermittelt werden sodann die gesellschaftlichen Kosten dieses Landnutzungssystems, die sich im Vergleich mit anderen als gering erweisen. Der Erholungswert wird mittels Zahlungsbereitschaftsanalysen erhoben. Die Gegenüberstellung von Kosten und Nutzen, die Akzeptanz von Seiten der Landwirtschaft sowie weitere wichtige Aspekte sprechen dafür, dem extensiven Ackerbau einen Platz im Spektrum künftiger Landnutzungen einzuräumen.

It was not until the 1980s, however, that scientists began to recognize the complex ity of the factors causing the decline in forest growth and deterioration of fish populations in acidified lakes. The general feeling, based on correla tive research, was that long-range transported air pollution was the main cause. Proof, however, was difficult to obtain because of complex interac tions of various stress factors including natural ones.

Acidic Mining Lakes: Acid Mine Drainage, Limnology and Reclamation (Environmental Science and Engineering)
by Wim Salomons, Helmut Klapper, Walter GellerAcidification is a universal problem at all mining sites in which oxygenated water comes in contact with sulfide minerals or other reduced sulfur compounds. An International Workshop was held in September 1995 at the Department for Inland Water Research of the UFZ-Centre for Environmental Research in Magdeburg on the limnology of lakes created by open-cast lignite mining, emphasizing the often observed geogenic acidification after oxidation of pyrite. The volume has 25 chapters including a chapter with results of group discussions about the topics mentioned above and further problems that were identified during the meeting. The monograph gives a baseline of the state of science on the worldwide problem of geogenic acidification of lakes following human mining activities.
Acidic Deposition and Forest Soils: Context and Case Studies of the Southeastern United States (Ecological Studies #72)
by Dan Binkley Charles T. Driscoll H. Lee Allen Philip Schoeneberger Drew McAvoyKnowledge in the field of acidic deposition is expanding rapidly, and both ex perts and non-experts are challenged to keep up with the latest information. We designed our assessment to include both the basic foundation needed by non experts and the detailed information needed by experts. Our assessment in cludes background information on acidic deposition (Chapter 1), an in-depth discussion of the nature of soil acidity and ecosystem H+ budgets (Chapter 2), and a summary of rates of deposition in the Southeastern U.S. (Chapter 3). A discussion of the nature of forest soils in the region (Chapter 4) is followed by an overview of previous assessments of soil sensitivity to acidification (Chapter 5). The potential impacts of acidic deposition on forest nutrition are described in the context of the degree of current nutrient limitation on forest productivity (Chap ter 6). The results of simulations with the MAGIC model provided evaluations of the likely sensitivity of a variety of soils representative of forest soils in the South (Chapter 7), as well as a test of soil sensitivity criteria. Our synthesis and recommendations for research (Chapter 8) also serve as an executive summary. A complementary volume in the Springer-Verlag Ecological Studies series should be consulted for information on European forests. This volume, Acidic Deposition and Forest Decline in the Fictelgebirge, edited by E.-D. Schultze and O.L. Lange, also provides greater detail on the physiologic responses of trees than we present in our regional assessment.
Acid Rain in Europe: Counting the cost
by Helen Apsimon David Pearce Ece OzdemirogluThe environmental impacts of acid rain: on human health, on buildings and materials, on forests, freshwaters, crops and biodiversity and on global warming have been well-documented. Less is known about the extent and economic costs of these impacts. This book describes the first major implementation of an integrated scientific and economic assessment of the consequences of acid rain. It provides an extensive data review and examines how this unique approach to assessment modelling can be can be used to calculate an acidification cost per unit of pollutant in monetary terms. Part One focuses on the methodological issues of scientific measurement of acidification, dose-response relationships and economic approaches to acidification control. Part Two looks at the environmental impacts and economic consequences of acidification. Affected environmental media and human health are investigated in separate chapters, each including both scientific and economic analyses. Part Three provides a summary of the findings and makes recommendations for further application of these types of results to policy actions.

Acid Deposition and the Acidification of Soils and Waters (Ecological Studies #59)
by J.O. Reuss D.W. JohnsonThe majority of this book was written in 1983-84 while the senior author was a Visiting Scientist at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. We believe that the approach to the problem of acid deposition effects on soils and waters developed during this collaboration contains ele ments that are significantly different from most prior work in this area. Some of the material and the software used in the development of these concepts stem from earlier individual efforts of the authors. However, what we believe to be the more significant concepts concerning the processes by which alkalinity may be developed in acid soil solutions, and by which acid deposition may contrib ute to the loss of this alkalinity, were the result of this collaboration. The ultimate usefulness of these concepts in understanding and dealing with various aspects of the problems associated with acid deposition cannot be adequately gauged at the present time. They must first withstand tests of con sistency with available observation, and of direct experimentation. It is our hope that dissemination through this book will facilitate this process within the scientific community. The authors wish to thank the administration of the Environmental Science Division at ORNL, and the College of Agricultural Sciences at Colorado State University for their support in arranging this collaboration. We also wish to express our appreciation for the financial support provided by EPA. Personal thanks are due to Dr.
