At a time when the polar regions are undergoing rapid and unprecedented change, understanding exchanges of momentum, heat and salt at the ice-ocean interface is critical for realistically predicting the future state of sea ice. By offering a measurement platform largely unaffected by surface waves, drifting sea ice provides a unique laboratory for studying aspects of geophysical boundary layer flows that are extremely difficult to measure elsewhere. This book draws on both extensive observations and theoretical principles to develop a concise description of the impact of stress, rotation, and buoyancy on the turbulence scales that control exchanges between the atmosphere and underlying ocean when sea ice is present. Several interesting and unique observational data sets are used to illustrate different aspects of ice-ocean interaction ranging from the impact of salt on melting in the Greenland Sea marginal ice zone, to how nonlinearities in the equation of state for seawater affect mixing in the Weddell Sea.

The book s content, developed from a series of lectures, may be appropriate additional material for upper-level undergraduates and first-year graduate students studying the geophysics of sea ice and planetary boundary layers."

Why do some animals migrate? How does migration affect the gene pool? This book discusses these questions and more, in light of the high evolutionary costs and risks of mass movement. The editor presents a collection of topics explaining the migration of organisms through many examples of different groups of marine and non-marine organisms, from micro-invertebrates to large mammals.

This book presents various approaches to the resolution of the severe water resource issues of the Middle East, with particular emphasis on the Israeli-Palestinian water conflicts. The authors include leading Palestinian and Israeli water experts who have worked together on joint research projects aimed at building up mutual understanding and respect. The studies consider the various approaches that could be used to improve cooperation and solve the problems arising from conflicting interests.

This book provides an overview of ninety key concepts which often trouble those who are new to researching within the social sciences. It covers theories of knowledge, methodologies and methods. Each entry offers a definition of a concept, shows how researchers have used that concept in their research and discusses difficulties that the concept presents. The book supports those undertaking their own social research projects by providing detailed critical commentary on key concepts in a particularly accessible way. In exploring these concepts, a wide range of research reports across many different fields are described. These include not only classic accounts, but also a broad selection of recent studies, some written by new researchers. The book will be useful for higher-education students carrying out projects within social science faculties at the end of their first degree or during a master's programme, though it will also be helpful for those undertaking doctoral research, and some entries have been written with the production of a thesis in mind. This second edition of Research Methods: The Key Concepts provides a more comprehensive and up-to-date coverage, as old entries have been updated and 19 new entries added. It helps new researchers to navigate the changing landscape of social research by recognising a) the changes in the ways researchers are thinking about knowledge and acquiring knowledge, b) the increasing use of digital tools to collect data, and c) the desire many contemporary researchers feel to promote social justice through their research.

This book describes the interdisciplinary work of USAID's Famine Early Warning System (FEWS NET) and its influence on methodological and development policies in the US. This book describes FEWS NET's systems, methods and presents several illustrative case studies that will demonstrate the integration of both physical and social science disciplines in its work. The aim of this book is to bring the work of USAID's Famine Early warning System Network into the public domain.

Fire Ecology of Tropical Ecosystems gives an extensive explanation of historic and current fire situations in the tropics, describing the fire ecology of tropical ecosystems from around the globe. Eighteen groups of leading researchers explain the many different aspects and roles of fire in tropical ecosystems. Regional chapters address a set of common subjects including the causes of fire, typical fire behavior, and elements of the fire regime. In addition, they study the impacts of human land use, landscape fragmentation and climate change on the fire environment and the challenges of fire management in these ecosystems. The common set of topics provides consistency among the chapters and facilitates comprehensive understanding of fire s place in tropical ecology. This cohesive book covers unique aspects of fire in each ecosystem and includes a discussion of common elements to enable comparisons and syntheses of fire effects in disparate tropical ecosystems. Current scientific literature is too fragmented: it hampers the understanding of tropical fire ecology and degrades all global studies of land cover change and global carbon emissions. Fire

Ecology of Tropical Ecosystems fills a large void in our current understanding of how fire affects terrestrial biota.

The book opens with a general explanation of fire in the tropics, giving the examples of Oazaca, Mexico in 1998 and Roraima, Brazil in 1997-1998. It follows with the concepts and principles of wildland fire, including heat transfer, fire behavior, fuels, weather and climate.

Chapters 3-19 cover the implications of fire in Asia, Africa, Australia, Central and South America, Pacifica and Pantropical, addressing the causes, fire behavior, severity, fire and land use, fire and landscapes (fragmentation and connectivity), fire, climate and climate change, fire regimes (why frequency matters), issues for fire management and regional issues of specific importance or interest. An overview at the end of the book considers the global fire regime conditions, threats, and opportunities for fire management in the tropics."

Asian river basins are undergoing rapid transformation. This volume considers the implications of the environmental change-development nexus for water management, river health and hazard awareness. As Biswas and Tortajada (2011) have recently commented, water management in Asia will likely change more in the next twenty years than in the last 2000 years. Critical environmental trends include decreasing flows of water and sediment due to dam construction and increased water extraction, land use change (especially forest removal), encroachment and degradation of floodplain and wetland environments, increased water demand and concerns about water security, urban expansion and associated pollution of rivers and contamination of groundwater reserves. These challenges are being reframed by new approaches to water management which represent a transition from engineering-dominated approaches towards integrated water management, from technology transfer to adaptive technologies. The volume comprises an introduction and five chapters. Brierley and Callum reframe approaches to river repair within emerging theories of in ecology and earth science which regard nature as a complex adaptive system replete with inherent uncertainties. These ideas are mirrored in the four case study chapters which deal with water governance in the Mekong Basin (Hirsch); hybrid adoption of water resource technologies in India (Barbanente et al.); determination of sediment dynamics in Java Rijsdijk); and ecological conservation imperatives in the headwaters of the Yellow, Yangtze and Mekong rivers in western China (Li et al.).

It is difficult for me to recollect a time when I was not fascinated with the very notion of a desert. Walt Disney's film, The Living Desert, which I initially saw when I was 8 years of age, provided me with my first glimpse of this wondrous yet seemingly ho stile environment. The images were hypnotic and captivating. I looked on in amazement at the promenade Cl deux of the male and female scorpions during courtship. Their rhythmic and coordinated movements as they grasped one another made them appear to glide in unis on over the surface of the sand, each individual totally absorbed with its partner. In the next minute the fern ale had suddenly and utterly transformed herself like some Jekyll and Hyde act, into an aggressive predator whose prior gregarious embrace was now a hold of death for the male. The indomitable desert grasshopper mouse, the ever sentient kit fox, the graceful shovel-nosed snake swimming in an endless sea of sand.

My interest in the behaviour and movements of birds of arid and semi-arid ecosystems began when my wife, Sue Milton, and I were Roy Siegfried, Director, at that time, of the Percy approached by Prof. FitzPatrick Institute of African Ornithology, to set up a project to investigate granivory in the South African Karoo. Sue and I spent some time finding a suitable study site, setting up accommodations and an automatic weather station at Tierberg, in the southern Karoo near the village of Prince Albert, and planning projects. Among our first projects was a transect where we noted plant phe nology, measured seed densities on the soil surface, counted birds, observed ant activity, measured soil surface temperatures and col lected whatever climate data we could at 40 sites along a 200-km oval route. Along the way, we became interested in the marked presence and absence of birds at certain sites - abundant birds one day, and very few birds at the same site a month later. Subsequent counts along fixed transects through shrublands confirmed that a number of bird species were highly nomadic over short and long distances, locally and regionally, leading to speculation on how widespread these movements were in the arid ecosystems of the world."

Modern seismology has faced new challenges in the study of earthquakes and their physical characteristics. This volume is dedicated to the use of new approaches and presents a state of the art in historical seismology. Selected historical and recent earthquakes are chosen to document and constrain related seismic parameters using updated methodologies in the macroseismic analysis, field observations of damage distribution and tectonic effects, and modelling of seismic waveforms. A critical re-evaluation of historical accounts and early seismograms provides us with the basis for a realistic seismic hazard assessment. This book is dedicated to the memory of Jean Vogt (1929 - 2005).

Audience This book is of value to seismologists, earthquake geologists, engineering seismologists, earth scientists and historians of catastrophes.

This volume presents peer-reviewed papers from the NATO Advanced Research Workshop on Atmospheric Boundary Layers held in April 2006. The papers are divided into thematic sessions: nature and theory of turbulent boundary layers; boundary-layer flows: modeling and applications to environmental security; nature, theory and modeling of boundary-layer flows; air flows within and above urban and other complex canopies: air-sea-ice interaction.

There are many reasons why strategic intelligence is required to support policy decisions. These primarily stem from the nature of today's kno- edge society with two contrasting trends. On the one hand, there is a trend of increasing human intelligence in the economic, social and political s- tems. On the other hand, there is a trend towards dissolving certainties about the problems and solutions of today's society. Clearly, more inf- mation does not necessary imply more certainties on how to act. What is more, the same facts are often interpreted in markedly different ways: the same policy relevant information can - and often does - results in confli- ing framing of a problem by different stakeholders. This is mainly due to competing assumptions, rather then because of inconsistent facts. The- fore, it is not surprising that policy-makers are calling for strategic intel- gence to support their understanding of today's challenges, including the relevant aspects of science and technology, their impact and their possible future developments. Over the last 15 years, Europe has rapidly adopted the practice of dev- oping and using Impact Assessment (IA) tools to support decision-making. Formal procedures and guidance for IA are well established within the European Commission and in most EU Member States. The adoption of IA procedures alone, however, does not guarantee that every policy domain is actually using the full potential of these assessment tools in the preparation of policies and legislation.

With detailed data from nine sites around the world, the authors examine how the so-called 'fragmentation' of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. 'Rangelands' make up a quarter of the world's landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

Drawing on ethnographic and archival research, Changing Forests explores how the indigenous Lenca community of La Campa, Honduras, has conserved and transformed their communal forests through the experiences of colonialism, opposition to state-controlled logging, and the recent adoption of export-oriented coffee production. It merges political ecology, collective-action theories, and institutional analysis to study how the people and forests have changed through socioeconomic and political transitions encompassed in three broad phases: (1) the premodern period, which considers historic perturbations in western Honduras from the period of colonialism into the middle of the twentieth century; (2) the period of state-led logging and intervention in La Campa, which caused major degradation in forest cover; and (3) the recent period in which export coffee production transformed property rights, and people s perceptions of the forest gained new conservationist and economic dimensions. Each phase entails perspectives and experiences that influenced human use of forests, and shaped subsequent transformations.

Growing social heterogeneity, population growth, and market integration present challenges for sustainable forest management, but satellite images show that forest cover has expanded since the community prohibited logging in 1987. The indigenous people have created a watershed reserve and agroforestry cooperatives, and maintain forests as part of a resilient livelihood strategy."

The Middle Paran river is one of the largest in the world. Exceptionally rich in fauna and flora, it provides researchers with a glimpse into an ecosystem yet undisturbed by human civilization. This fascinating book covers all the key aspects of the Paran 's fluvial limnology and ecology, arranged in discrete and easily navigable sections. First, the physical and chemical environment is explained, then the river 's plant life, followed by its invertebrate life, and finally the vertebrates that inhabit the river.

Dust storms are a vital component of the environment. This book explores and summarises recent research on where dust storms originate, why dust storms are generated, where dust is transported and deposited, the nature of dust deposits and the changing frequency of dust storms over a range of time-scales. It is the first global study of causes and effects of dust storms, which are one of the increasing nature catastrophes.

This book compares and contrasts traditional crime scenes with scenes of climate crisis to offer a more expansive definition of crime which includes environmental harm. The authors reconsider what crime scenes have always included and might come to include in the age of the Anthropocene - a new geological era where humans have made enough significant alterations to the global environment to warrant a fundamental rethinking of human-nonhuman relations. In each of the chapters, the authors reframe enduringly popular Arctic scenes, such as iceberg hunting, cruising and polar bear watching, as specific criminal anthroposcenes. By reading climate scenes in this way, the authors aim to productively deploy the representation of crime to make these scenes more engaging to policymakers and ordinary viewers. Criminal Anthroposcenes brings together insights from criminology, climate change communication, and tourism studies in order to study the production and consumption of media representations of Arctic climate change in the hope of to mobilizing more urgent public and policy responses to climate change.

Although numerous books have been written on both monitoring and modelling of coastal oceans, there is a practical need for an introductory multi-disciplinary volume to non-specialists in this field. The articles commisioned for this book, organized into four major themes, are written by experts in their disciplines while the text is intended for scientists who do not have extensive training in marine sciences and coastal zone management. As such, the articles in this monograph can be a valuable reference for practicing professionals. The first section introduces the complex physical processes with main emphasis on waste disposal in the coastal ocean. Following this, examples of instrumentation techniques that are commonly used for measuring different properties of oceans are discribed. Coastal and estuarine transport and dispersion modelling is introduced in the next section with examples from different parts of the world. The last section provides an overview of coastal disasters such as tropical cyclones, storm surges and oil spills.

This anthology of studies by the eminent geographer and climate scientist Eduard Bruckner (1862-1927) on anthropogenic climate change and the social, political and economic impact of climate variations on societies in historical times, assembles his pioneering work in English for the first time. The issues discussed by Bruckner are now considered to be among the most pressing facing modern society and climate research. At the turn of the twentieth century, Bruckner was one of the central protagonists in a vigorous debate in science and society about global climate variability and its political and economic significance. The studies published here were chosen to demonstrate Bruckner 's wide-ranging scientific interest in climate variability, his extensive empirical research and theoretical analysis of climate change, his assessment of contemporary analyses and thinking about anthropogenic climate change (such as the widespread concern about desiccation), and how he approached the questions of the transfer of scientific knowledge into society. In many ways Bruckner was a thoroughly modern scientist, convinced, for example, that the issue of climate change and its impact was of considerable scientific merit and that future climate changes are of great significance for the well-being of humankind as well as for the global balance of political and economic relations. Bruckner 's formidable ideas should have a significant impact on our present views of climate, climate variability and climate impact.

by Peter J. Roussopoulos, Director, Southern Research Station The world and its ecosystems are repeatedly punctuated by natural disturbances, and human societies must learn to manage this reality Often severe and unp- dictable, dynamic natural forces disrupt human welfare and alter the structure and composition of natural systems Over the past century, land management ag- cies within the United States have relied on science to improve the sustainable management of natural resources Forest economics research can help advance this scientifc basis by integrating knowledge of forest disturbance processes with their economic causes and consequences As the twenty-frst century unfolds, people increasingly seek the goods and services provided by forest ecosystems, not only for wood supply, clean water, and leisure pursuits, but also to establish residential communities that are removed from the hustle and bustle of urban life As vividly demonstrated during the past few years, Santa Ana winds can blow wildfres down from the mountains of California, incinerating homes as readily as vegetation in the canyons below Hurricanes can fatten large swaths of forest land, while associated foods create havoc for urban and rural residents alike Less dramatic, but more insidious, trees and forest stands are succumbing to exotic insects and diseases, causing economic losses to private property values (including timber) as well as scenic and recreation values As human demands on public and private forests expand, science-based solutions need to be identifed so that social needs can be balanced with the vagaries of forest disturbance processes

For more than 40 years I have been engaged in timberline research. Thus, one could suppose that writing this book should not have been too difficult. It was harder, however, than expected, and in the end I felt that more questions had arisen than could be answered within its pages. Perhaps it would have been easier to write the book 30 years ago and then leave the subject to mature. Lastly it was the late Prof. Heinz Ellenberg who had convinced me to portray a much needed and complete picture of what we know of the timberline with special respect to its great physiognomic, structural and ecological variety. The first version of this book was p- lished in the German language (Holtmeier, 2000). Nevertheless, I was very delighted when Prof. Martin Beniston encouraged me to prepare an English edition for the series 'Advances in Global Change Research', which guaranteed a wider circulation. Timberline is a worldwide and very heterogeneous phenomenon, which can only be presented by way of examples. My own field experience is necessarily limited to certain timberline areas, such as the Alps, northern Scandinavia, northern Finland and many high mountain ranges in the western United States and Canada. However, my own observations and the results of my and my previous collaborators research were essential for developing the concept of the book and became integrated into the picture of timberline that is presented in the following chapters.

This book covers fundamental aspects of spatial data modelling specifically on the aspect of three-dimensional (3D) modelling and structuring. Realisation of "true" 3D GIS spatial system needs a lot of effort, and the process is taking place in various research centres and universities in some countries. The development of spatial data modelling for 3D objects is the focus of this book.

The ''Aral Sea Encyclopedia'' is the first one in the new series of encyclopedias about the seas of the former Soviet Union. Preparing it we faced certain difficulties. The thing is that this encyclopedia is a monument to the sea that is disappearing during our lifetime. The world community considers the situation with the Aral Sea and all changes that occurred in its whereabouts in the recent decades as one of the most serious, if not disastrous anthropogenic environmental crises of the 20th century. Before 1960, this was a water-abundant sea-lake that was fourth among world lakes after the Caspian Sea (USSR, Iran), the Great Lakes (USA, Canada) and Victoria Lake (Africa). This was a real ''pearl'' among the sands of the largest deserts, the Karakums and the Kyzylkums. Navigation between the sea ports Muinak and Aralsk and fisheries famous for the Aral breams, barbells, sturgeons, shemaya, and others were developed here. One could find beautiful recreational zones and beaches here. The deltas of the Amudarya, the major river of Central Asia, and the Syrdarya bringing their waters into the Aral Sea were famous for their biodiversity, fishery, muskrat rearing, reed prod- tion. The local population found occupations related to the water infrastructure.

Despite their importance in sustaining livelihoods for many people living along some of the world s most populous coastlines, tropical mangrove forests are disappearing at an alarming rate. Occupying a crucial place between land and sea, these tidal ecosystems provide a valuable ecological and economic resource as important nursery grounds and breeding sites for many organisms, and as a renewable source of wood and traditional foods and medicines. Perhaps most importantly, they are accumulation sites for sediment, contaminants, carbon and nutrients, and offer significant protection against coastal erosion.

This book presents a functional overview of mangrove forest ecosystems; how they live and grow at the edge of tropical seas, how they play a critical role along most of the world s tropical coasts, and how their future might look in a world affected by climate change. Such a process-oriented approach is necessary in order to further understand the role of these dynamic forests in ecosystem function, and as a first step towards developing adequate strategies for their conservation and sustainable use and management. The book will provide a valuable resource for researchers in mangrove ecology as well as reference for resource managers."
