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."

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."

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.

This book is devoted to the Anthropocene, the period of unprecedented human impacts on Earth's environmental systems, and illustrates how Geographers envision the concept of the Anthropocene. This edited volume illustrates that geographers have a diverse perspective on what the Anthropocene is and represents. The chapters also show that geographers do not feel it necessary to identify only one starting point for the temporal onset of the Anthropocene. Several starting points are suggested, and some authors support the concept of a time-transgressive Anthropocene. Chapters in this book are organized into six sections, but many of them transcend easy categorization and could have fit into two or even three different sections. Geographers embrace the concept of the Anthropocene while defining it and studying it in a variety of ways that clearly show the breadth and diversity of the discipline. This book will be of great value to scholars, researchers, and students interested in geography, environmental humanities, environmental studies, and anthropology. The chapters in this book were originally published as a special issue of the journal Annals of the American Association of Geographers.

Catherine Boone examines political regionalism in Africa and how it affects forms of government, and prospects for democracy and development. Boone's study is set within the context of larger theories of political development in agrarian societies. It features a series of compelling case studies that focus on regions within Senegal, Ghana, and Côte d'Ivoire and ranges from 1930 to the present. The book will be of interest to readers concerned with comparative politics, Africa, development, regionalism and federalism, and ethnic politics.

As a continent of extreme, rare and complex environments, Australia has produced a startling group of ecological pioneers. Australian thinkers and innovators have made some truly original contributions to ecological thought. This study traces the emergence of ecological awareness in Australia. By constructing a social history with chapters focusing on different fields in the arts, sciences, politics and public life, Martin Mulligan and Stuart Hill are able to bring to life the work of significant individuals.

The Grand Ethiopian Renaissance Dam (GERD) will not only be Africa's largest dam, but it is also essential for future cooperation and development in the Nile River Basin and East African region. This book, after setting out basin-level legal and policy successes and failures of managing and sharing Nile waters, articulates the opportunities and challenges surrounding the GERD through multiple disciplinary lenses. It sets out its possibilities as a basis for a new era of cooperation, its regional and global implications, the benefits of cooperation and coordination in dam filling, and the need for participatory and transparent decision making. By applying law, political science and hydrology to sharing water resources in general and to large-scale dam building, filling and operating in particular, it offers concrete qualitative and quantitative options that are essential to promote cooperation and coordination in utilising and preserving Nile waters. The book incorporates the economic dimension and draws on recent developments including: the signing of a legally binding contract by Egypt, Ethiopia and Sudan to carry out an impact assessment study; the possibility that the GERD might be partially operational very soon, the completion of transmission lines from GERD to Addis Ababa; and the announcement of Sudan to commence construction of transmission lines from GERD to its main cities. The implications of these are assessed and lessons learned for transboundary water cooperation and conflict management.

These three volumes present an original exploration of all aspects of water--social, cultural, political, religious, historical, economic and technological--from ancient times until the present day. Among the varied themes, the contributors examine the changing histories of water as a private or common good, the politics of water at local, urban, national and international level, water in cities, great river plans, dams, river biographies, and cultural constructions of water--images of water in religion, myth, literature and art. With empirical and ethnographic case studies from around the world the three volumes together represent one of the most complete and up to date accounts of the central role of water in the history and development of humanity.

Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

This is an extraordinary 1997 collection of essays about landscape. With a lively and engaging style, George Seddon considers everything from creating a garden in Freemantle, to locating ancient plants while wandering in a far North Queensland rainforest to analysing the geological features on either side of the tram tracks in Collingwood. Yet while the book celebrates Australia, and covers many topics that seem familiar and everyday, it is challenging and provocative. Seddon is acutely aware of the moral and environmental aspects of history and is able to present local and regional history on a grand scale. Landprints reflects a lifetime devoted to questions about landscape: the ways we use and abuse the land, how Australian landscapes are different from European landscapes and how this land makes those who live on it uniquely, if ambiguously, Australian.

This book contains a selection of papers from the International Military Geology and Geography Conference, held at the U.S. Military Academy, West Point, New York in June 2003. Studies in Military Geography and Geology expands a series of recent publications originating from conferences and symposia on military geology that began in 1994. The 25 contributions address a broad range of military topics ranging from the strategic perspective, through analyses of historical battles at the operational and tactical levels, to the use of advanced technologies applied to present-day military problems.

First published in 1987, Maritime Boundaries and Ocean Resources is a collection of essays which examines the political jurisdiction of ocean boundaries and the affects that this has on the world's oceans. It examines how the intensification of ocean use has raised questions of how rational planning, and the management of the oceans can avoid increasingly environmental damage and sea use conflict and examines the ocean as a tool for space, trade and communication. It also addresses the creation of integrated regional planning for ocean management.

The current scenario provides an ideal opportunity to confer higher priority to the marine resources of the Indian Ocean, particularly in terms of integrated management of the deep sea, shallow sea and coastal resources. This will maximize their potential in the sustainable development goal (SDG) pattern, leading to an appropriate environmental management. Therefore, this book aims to provide an overview of the area and to highlight the potential market opportunities represented by this vast and rapidly developing nation. In doing so the following aspects have been covered: Exclusive title focussing on mineral resources of Indian ocean. Discusses living, nonliving, ocean waves and tidal energy, ocean environment and protection aspects. Includes information on key themes, details of organizations associated with the Indian Ocean. Illustrates deep sea mining technology and environmental perspectives. Covers hydrocarbons-sub sea oil and gas, minerals from placer deposits to deep sea nodules, sea floor massive sulphides and cobalt rich encrustations.

This second edition, enhanced with more than 30 new figures, provides an up-to-date overview of physical geography suitable for all those with a personal or professional interest in environmental processes, climate change and understanding of the Earth’s landforms and dynamics. The text provides explanations of processes, enabling the reader to understand the interconnected nature of the Earth’s system, and has been updated to include new developments and case studies with insights from satellite observations and data analysis using artificial intelligence.

The book begins by outlining the nature of the Earth system, concepts around environmental thresholds and feedbacks, planetary boundaries for human survival, and humans as a dominant driver of environmental change. The second chapter examines features associated with plate tectonics, the role of weathering and erosion in shaping landscapes, and soil functions and management. Chapter 3 deals with the climate system, describing drivers of the major atmospheric and oceanic circulation systems, the natural greenhouse effect, and regional climate and weather experienced for different zones across the planet. The global carbon cycle and long-term climate change are considered in Chapter 4 before moving on to tackle the latest knowledge on contemporary and future climate change, its impacts, mitigation and adaptation. Chapter 5 facilitates key understanding of hydrology, river channel dynamics, water quality, coastal processes, glacier dynamics and cold region landforms while Chapter 6 deals with the distribution and patterns of life on Earth and of the underlying processes that result in these patterns. The book concludes with a brief overview of considerations for managing environmental change and hazards, and requirements for achieving the UN’s Sustainable Development Goals.

This reader-friendly text brings together wide-ranging subject areas from across physical geography, covering the basics of the subject at a level suitable for those about to embark on a university degree or for those who just want to get a solid basic understanding of the physical environment around them. The book, which contains box features with examples and a glossary to aid understanding, acts as a primer for further study, or in itself can be used as a basic aid to understanding fundamental principles and processes associated with physical geography.

For those addressing ecological and natural resource management problems this volume presents a set of coherent, cross-referenced perspectives on incorporating the spatial representation and analytical power of GIS with agent-based modeling of evolutionary and non-linear processes and phenomena. Many recent advances in software algorithms for incorporating geographic data in modeling social and ecological behaviors and also the success in applying such algorithms have not been adequately represented in the present literature. This book fills that gap and provides much needed information on applications for the research community as well as those in the management of natural resources.

This text is a complete introduction to reseah methods in political science, covering all the topics typically included in a one semester undergraduate-level course. h concentrates on the basics of what a student needs to know how to do in order to be an effecise consumer of scientific research and begin to conduct his or her own research projects. The approach of 'learning by doing" is encouraged through nUmeroUs examples and exercises. The book is written in an informal style, with minimal use of technical jargon. Alan D. Monroe (Ph.D.. Indiana Univrsity) has taught introductory research methods at Illinois Slate University for more than 25 years. He has published research on a variety of topics, particularly of public opinion and public policy in the U.S.. and has also conducted a number of research projects for governmental agencies and private clients, including surveys for political campaigns.

This book presents approaches to landscape modelling not only from geography but also from various related disciplines, especially from applied mathematics, computer science, and geophysics. New methods of terrain representation, analysis and classification are presented as well as short- and long-term process models. The intention of the book is not to give a complete overview of these broad and complex topics, but to stimulate interdisciplinary cooperation and to encourage scientists to consider the ideas of related disciplines.

The Texture of Industry is an overview of the industrialization of North America using material evidence - sites, structures, and artifacts - to fill out the story of America's `industrial archaeology', drawing upon techniques from archeometry, field archaeology, art history, and architectural recording. The book is organized around a discussion of the industrial experience. Several sites and artifacts - ones that can be visited by the public - are studied in depth.

This textbook introduces political ecology as an interdisciplinary approach to critically examine land and environmental issues. Drawing on discourse and narrative analysis, Marxist political economy and insights from natural science, the book points at similarities, differences and inter-connections between environmental governance in the global North and South. A wide range of carefully curated case studies are presented, with a particular focus on Africa and Norway. Key themes of power, justice and environmental sustainability run through all chapters. The authors challenge established views and leading discourses and present research findings that may surprise readers. Chapters cover topics including wildlife conservation, climate change and conflicts, land grabbing, the effects of population growth on the environment, jihadism in the African Sahel, bioprospecting, feminist political ecology, and struggles around carbon mitigation within a fossil fuel-based economy. This introductory text provides tools and examples for both undergraduate and postgraduate students to better understand on-going struggles about some of the world's most urgent challenges.
