Floodplains are ecosystems which are driven by periodic inundation
and oscillation between terrestrial and aquatic phases. An
understanding of such pulsing systems is only possible by studying
both phases and linking the results into an integrated
overview.
This book discusses water resources management in Romania from a hydrological perspective, presenting the latest research developments and state-of-the-art knowledge that can be applied to efficiently solve a variety of problems in integrated water resources management. It focuses on a wide range of water resources issues - from hydrology and water quantity, quality and supply to flood protection, hydrological hazards and ecosystems, and includes case studies from various watersheds in Romania. As such, the book appeals to researchers, practitioners and graduates as well as to anybody interested in water resources management.
Coastal Dunes Form and Process Edited by Karl F. Nordstrom Norbert Psuty Institute of Marine and Coastal Sciences, Rutgers University, New Brunswick, New Jersey 08903, USA and Bill Carter Department of Environmental Studies, University of Ulster, Coleraine, Co. Londonderry, BT52 1SA, Northern Ireland Coastal Morphology and Research Series Series Editor: Eric C. F. Bird This book deals with the formation and establishment of coastal dunes--considering both forms and processes in a wide variety of environments. These landforms are among the most sensitive to environmental change, yet they provide extensive protection against both short-term erosion and flooding and long-term sea-level rise. Until now, there has not been any major book to deal specifically with coastal dunes. The current volume surveys a range of dune features, such as the ephemeral characteristics in the rapidly subsiding Mississippi delta, the extensive sand sheets of Australia and South Africa and the Holocene dunes of Western Europe and North America. This book will provide essential background information for ecological and management studies of coastal dunes. It will be of immense value to geomorphologists, ecologists and other environmental scientists who work on the management of coastal dunes.
Compared to many other regions of the world, Africa is particularly vulnerable to the effects of climate change and variability. Widespread poverty, an extensive disease burden and pockets of political instability across the continent has resulted in a low resilience and limited adaptative capacity of African society to climate related shocks and stresses. To compound this vulnerability, there remains large knowledge gaps on African climate, manifestations of future climate change and variability for the region and the associated problems of climate change impacts. Research on the subject of African climate change requires an interdisciplinary approach linking studies of environmental, political and socio-economic spheres. In this book we use different case studies on climate change and variability in Africa to illustrate different approaches to the study of climate change in Africa from across the spectrum of physical, social and political sciences. In doing so we attempt to highlight a toolbox of methodologies (along with their limitations and advantages) that may be used to further the understanding of the impacts of climate change in Africa and thus help form the basis for strategies to negate the negative implications of climate change on society.
The Siberian environment is a unique region of the world that is both very strongly affected by global climate change and at the same time particularly vulnerable to its consequences. The news about the melting of sea ice in the Arctic Ocean and the prospect of an ice-free shipping passage from Scandinavia to Alaska along the Russian north coast has sparked an international debate about natural resource exploitation, national boundaries and the impacts of the rapid changes on people, animals and plants. Over the last decades Siberia has also witnessed severe forest fires to an extent that is hard to imagine in other parts of the world where the po- lation density is higher, the fire-prone ecosystems cover much smaller areas and the systems of fire control are better resourced. The acceleration of the fire regime poses the question of the future of the boreal forest in the taiga region. Vegetation models have already predicted a shift of vegetation zones to the north under s- narios of global climate change. The implications of a large-scale expansion of the grassland steppe ecosystems in the south of Siberia and a retreat of the taiga forest into the tundra systems that expand towards the Arctic Ocean would be very signi- cant for the local population and the economy. I have studied Russian forests from remote sensing and modelling for about 11 years now and still find it a fascinating subject to investigate.
This chapter has shown a small sample of GIS applications in economic devel- ment. GIS is a powerful tool for data analysis and presentation, and the economic development rami cations are truly signi cant. The speed at which data and stra- gies can be coordinated is clearly changing the way economic developers approach their job. There are a number of important trends that are likely to result in GIS becoming more pervasive in the economic development community. These include declining costs of GIS software, increased computing power, and the growth of Web-based GIS applications. There also has been increase in GIS skills among economic development professionals. References Bastian, L. (2002). Getting the best from the web.

This book integrates the analyses of organic carbon and carbonate accumulation in soil and lake sediment in a typical arid region of China that has experienced significant climate and land-use changes. It demonstrates that carbonate accumulation greatly exceeds organic carbon in both soil and sediment. It also shows that intensive cropping with sound land management in the arid land not only increases soil organic carbon stock, but also enhances accumulation of soil carbonate, particularly in subsoils. Carbon accumulation in the lake sediment increased between 1950 and 2000, after which it declined, and the authors explore how human activity and climate change may have caused the changes in carbon burial in the lake sediment. This book is of interest to researchers in a number of fields such as soil science, limnology and global change, as well as to the policy-makers.
This book presents a new degree theory for maps which commute with a group of symmetries. This degree is no longer a single integer but an element of the group of equivariant homotopy classes of maps between two spheres and depends on the orbit types of the spaces. The authors develop completely the theory and applications of this degree in a self-contained presentation starting with only elementary facts. The first chapter explains the basic tools of representation theory, homotopy theory and differential equations needed in the text. Then the degree is defined and its main abstract properties are derived. The next part is devoted to the study of equivariant homotopy groups of spheres and to the classification of equivariant maps in the case of abelian actions. These groups are explicitely computed and the effects of symmetry breaking, products and composition are thorougly studied. The last part deals with computations of the equivariant index of an isolated orbit and of an isolated loop of stationary points. Here differential equations in a variety of situations are considered: symmetry breaking, forcing, period doubling, twisted orbits, first integrals, gradients etc. Periodic solutions of Hamiltonian systems, in particular spring-pendulum systems, are studied as well as Hopf bifurcation for all these situations.
Arising initially from a conference, the papers published here have been integrated into book form to provide information on human activities and the tropical rainforest in the past and present, and on the possible future of the rainforest, in a unique way. Other books have considered some, but not all, of these themes; however, none has stressed the continuity of change over time and its possible outcome for the people of the forest as well as for the forest itself. Because of the approach taken, this book should appeal across traditional disciplinary boundaries. Indeed a prime aim has been to suggest that rainforest, because of its complexity and the complexity of people-rainforest relationships throughout time, deserves study from a broad perspective. This book poses more questions than answers about the rainforest and it is hoped that it will encourage readers to think about the rainforest in a wider way than hitherto. This book is aimed at geographers (physical and human), social anthropologists, archaeologists, pedologists, foresters and tropical botanists and will be of value to graduates of various disciplines setting out to research the rainforest.
The 1848 treaty of Guadalupe Hidalgo that ended the Mexican-American War described a boundary between the two countries that was to be marked through a joint boundary commission effort. The section of the boundary along the Rio Grande from Presidio to the mouth of the Pecos River was arguably the most challenging, and it was surveyed by two American parties, one led by civilian surveyor M. T. W. Chandler in 1852, and the second led by Lieutenant Nathaniel Michler in 1853. Our understanding of these two surveys across the greater Big Bend has long been limited to the official reports and maps housed in the National Archives and never widely published. The discovery by Orville B. Shelburne of the journal kept by Dr. Charles C. Parry, surgeon-botanist-geologist for the 1852 party, has dramatically enriched the story by giving us a firsthand view of the Chandler boundary survey as it unfolded. Parry's journal forms the basis of From Presidio to the Pecos River, which documents the day-to-day working of the survey teams. The story Shelburne tells is one of scientific exploration under duress - surveyors stranded in towering canyons overnight without food or shelter; piloting inflatable rubber boats down wild rivers; rising to the challenges of a profoundly remote area, including the possibility of Indian attack. Shelburne's comparison of the original boundary maps with their modern counterparts reveals the limitations of terrain and equipment on the survey teams. Shelburne's book provides a window on the adventure, near disaster, and true accomplishment of the surveyors' work in documenting the course of the Rio Grande across the Big Bend region.
This publication collects the results of a practical experience of survey, through the direct control of satellite images from high to medium resolution, over areas subjected to desertification problems. The problems of the local population are closely tied to the equilibrium in the management of the territory, which is compromised by the difficulties of maintaining traditional methodologies of management. The new survey technologies, based on the Remote Sensing and Geographic Information System, allow analyzing the details of the present situation and point out the dynamism of the phenomena and the impacts with anthropogenic activities. Training has been carried out in the Tozeur area, in central Tunisia, where participants had the chance to analyze on the field a series of different aspects. It has also been possible to discuss similar experiences in distant territories and the importance of the physical processes of desertification. During the development of the intensive training on the job, visits to entrepreneurial truths concerning the management of the territory have been carried out. The analyzed area finds in tourism an answer to the necessities of improving the living conditions of the population. Specialists from twelve nations presented actions of management of the territory, with detailed attention on environmental security and the conditions of the territory. From the observations carried out the fragility of the landscape of the oases has emerged, which are subjected to total anthropogenic management and therefore closely linked to the availability of the specialized workers in the traditional methodologies. It is natural that the management of the lands changesaccording to modern technologies, but, with a too fast pace, this evolution risks to upset the management of the territory. The exchange of information, the ability to map the variations, the dialogue between the parts, will favor the maintenance of the political security in the Mediterranean region. This experience of cooperation and association constitutes a precedent for the development of a system of high education courses to be provided to the local communities for the common wellbeing.
Over the past decade the significant advances in real-time ocean observing systems, ocean modelling, ocean data assimilation and super-computing has seen the development and implementation of operational ocean forecast systemsof the global ocean. At the conclusion of the Global Ocean Data Assimilation Experiment (GODAE) in 2008 ocean analysis andforecasting services were being supported by 12 international centres. This book is about ocean forecasting - a maturing field which remains an active area of research, and includes such topics as ocean predictability, observing system design, high resolution ocean modelling and ocean data assimilation. It presents the introduction to ocean forecasting which provides a foundation for new opportunities in areas of coupled bio-geochemical forecasting and coupled atmosphere-wave-ocean forecasting. The book describesan updated account ofresearch and development to improve forecast systems, determining how best to service the marine user community with forecast information as well as demonstrating impact to their applications. It also discusses operational centresthat are now supporting a range of real-time ocean services including online graphical and data products for their user communities and their feedback on the quality of information. The contents of this book are aimed at early career scientists and professionals with an interest in operational oceanography and related ocean science. There are excellent opportunities for exciting careers in the emerging field of operational oceanography in order to address current and future challenges as well as provide the supporting services to a rapidly growing user community.
First published in 1966 these collected papers, written by the distinguished and visionary climatologist Hubert H. Lamb, describe how climates come about and give a history of climatic changes from the last ice-age to the 1960s.
First published in 1988, this is a reissue of a groundbreaking collection of essays written by Hubert Lamb, one of the world's foremost experts on weather and climate and a uniquely authoritative voice in the history of climatology. Hubert Lamb is able to provide a mature assessment of the effect of weather on people, and vice versa. His is a uniquely authoritative voice in the current debates about today's environment and the prospects for the future. After a general introduction the book is divided into three parts. The first part consists of a chronological series of portraits of climate and its impact on human affairs and the environment. These extend from the warm climates of the geological past to the current drought in Africa. There are several studies of the last few centuries and, in particular, of the various effects of the so-called ?little Ice Age?. The second part is concerned with the causes and mechanisms of climate and weather changes, including chapters discussing Christmas weather, fronts and volcanoes. In the final part Hubert Lamb looks to the future, and attempts to put into perspective some of the pessimistic forecasts currently available. The text, which is consistently authoritative but always readable, is augmented by numerous maps, diagrams and photographs.
This book is an original and novel contribution to flood hazard
assessment, climate change and land use change and is intended to
serve both as an effective source of information and a valuable
basis for priority setting and further technical, financial and
political decisions regarding flood hazard assessment. The study
area is located on the floodplain of the Ubaye River in the
Barcelonnette area, part of the Alpes de Haute Provence in
southeast France. The book offers a comparative overview of the
major challenges faced when dealing with flood hazards. The
research presented is intended to promote a deeper understanding of
how climate change and land use change processes have evolved from
past to present, and how they affect the flow regime of the Ubaye
River based on sound and reproducible scientific arguments. The
methodology implemented ranges from remote sensing interpretation
to hydrodynamic modeling and includes the application of spatial
and statistical modeling. The results of this research provide
essential information for policymaking, decision-making support and
flood hazard planning in the Barcelonnette area.
Why do we travel? Are holidays good for our health? What are the social and psychological factors that drive us to move? The Psychology of Travel provides an eclectic introduction to the range of travel experiences from commuting, to going on holiday, to studying abroad. Travel is a near-universal experience and manifests itself in various forms, from everyday experiences to exotic adventure, although it varies across time and cultures. The book unpacks the concept of travel, and engages with topics including migration, wellbeing, acculturation, wayfinding, slow travel, place attachment and nostalgia, and brings them into sharp focus in relation to globalisation and climate change, By asking what drives us to journey and offering key insights into the psychological factors behind different kinds of travel, The Psychology of Travel introduces the reader to new ways of thinking about global mobility and movement.
The Economic Geology of Iran is a complete and comprehensive book about mineral deposits, energy and water resources of Iran. Dr. Mansour Ghorbani has travelled to each of the huge variety of locations that feature the resources covered, personally verifying the details of them all. The book starts by describing the geography and physiography of Iran as well as its various climatic regions and the diverse corresponding vegetation. Then the book gives an excellent overview of the geology of the country, followed by the history of mining in Iran up to now. The author describes also the metallogenic and mineralization phases of Iran, its mineral zones and belts, and, more generally, the distribution of mineral deposits in the country. Dr. Ghorbani gives us also an analysis of the position of Iran in terms of global mineral resources, as well as the role that the country s mineral, energy and natural resources play in its overall economy. The book finishes with also provides a complete list of Iranian mineral deposits. This book is a perfect source of information for all students and researchers in the field of geo-science at the university level but also for mining and oil companies that would like to work, invest and get involved in such businesses in Iran.
Recent landslide events demonstrate the need to improve landslide
forecasting and early warning capabilities in order to reduce
related risks and protect human lives. In this thesis, local and
regional investigations were carried out to analyse landslide
characteristics in the Swabian Alb region, and to develop
prototypic landslide early warning systems.
The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. The volume addresses the following major topics: - Research results in measuring and observing aspects of the Arctic climate system and its processes across a range of time and space scales - Representation of cryospheric, atmospheric, and oceanic processes in models, including assimilation of observations into models - Our understanding of the role of the Arctic in the global climate system, its response to large-scale climate variations, and the processes involved.
This thesis includes a wealth of cave maps, as well as photos of the caves and karst morphologies. At the heart of the thesis is the important discovery of a flank margin cave with speleothem hiatuses and fossil invertebrate associations. The analysis of the structural and karst morphological elements surveyed in the main explored caves in Monti di Capo San Vito has made it possible to identify both the state of control of the processes of karstification in tectonic phases during the Plio-Pleistocene upliftings and the kinematic character of some karstified structures, linked at two speleogenetic phases. Furthermore, the surveying of karst forms on the relict sea-cliffs and particularly the exceptional discovery and dating of marine and continental incrustations in the Rumena cave, has yielded essential advances in our knowledge of past climatic events and eustatic level changes in the Mediterranean, as well as their influence on the evolution of the coastal belt. |
