To this day, there is a great amount of controversy about where, when and how the so-called supercontinents--Pangea, Godwana, Rodinia, and Columbia--were made and broken. Continents and Supercontinents frames that controversy by giving all the necessary background on how continental crust is formed, modified, and destroyed, and what forces move plates. It also discusses how these processes affect the composition of seawater, climate, and the evolution of life.
Rogers and Santosh begin with a survey of plate tectonics, and go on to describe the composition, production, and destruction of continental and oceanic crust, and show that cratons or assemblies of cratons became the first true continents, approximately one billion years after the earliest continental crust evolved. The middle part of the book concentrates on supercontinents, beginning with a discussion of types of orogenic belts, distinguishing those that formed by closure of an ocean basin within the belt and those that formed by intracontinental deformation caused by stresses generated elsewhere. This information permits discrimination between models of supercontinent formation by accretion of numerous small terranes and by reorganization of large old continental blocks.
This background leads to a description of the assembly and fragmentation of supercontinents throughout earth history. The record is most difficult to interpret for the oldest supercontinent, Columbia, and also controversial for Rodinia, the next youngest supercontinent. The configurations and pattern of breakup of Gondwana and Pangea are well known, but some aspects of their assembly are unclear. The book also briefly describes the histories ofcontinents after the breakup of Pangea, and discusses how changes in the composition of seawater, climate, and life may have been affected by the sizes and locations of continents and supercontinents.

Originally published in 1973. This collection of essays looks at the 'quantitative revolution' and the 'new geography' by some of the geographers who had a significant part in those innovations and looks ahead to further developments. The views in the chapters are diverse and offer a fascinating glimpse of the discipline of geography as the subject was undergoing such change and becoming more socially committed. They cover theory, spatial-systems theory, forecasting, human ecology and climatology alongside the teaching of the subject. The concerns of the contemporary geographer come across and are of interest today as these areas have developed still more.

This volume consists of twenty chapters addressing different aspects of the theme of fluvial processes and environmental change. The overall coverage is broad; scientifically, (from modelling to alluvial dating), geographically (from arid zone flash-flooding to glacial meltwaters) and in time (from contemporary process studies to the Quaternary). The introductory chapter sets the context, which is an attempt to show how studies of fluvial processes can help us in understanding and therefore predicting the impact of environmental change on our rivers, riverine resources and landscapes. Environmental change includes both climatic factors, however caused, and human impacts on river basins. The differentiation of these two factors is discussed in several chapters whilst others take a more holistic approach. Both climatic and human factors have, and will remain, to act together and so their interactions need to be understood. Fluvial Processes and Environmental Change is divided into five sections, commencing with the slope-catchment scale and proceeding to studies of channel response, then floodplain processes and floodplain response and finally two studies from glacierised basins. The volume originated as a two-day session of the British Geomorphological Research Group and contributors from Europe, the USA and Australia were included in order to provide a wide perspective on the topic. This book will be a valuable reference for postgraduates and researchers in fluvial geomorphology, hydrology, Quaternary science, geology and environmental science.

Published in 1959, this book presents a study of transport problems including those of the coordination of inland transport, and special problems of coordination in areas of urban transport, civil aviation, sea ports and arising problems in the course of the economic integration of Europe.

Provides readers with the fundamentals necessary for a basic understanding of the soil landscape. Divided into three major sections, it covers stratigraphy, geomorphology, hydrology, and the ways in which these geologic processes shape the landscape. Early chapters cover the textural characteristics of soil materials, fluvial systems, hillslope sediments and transitional environments. Later chapters explore volcanics, saprolite, the evolutionary process of landscapes, rates of denudation, streams, hillslope processes and mass movement. Included at the end of the chapters are lists of references, figures, tables and additional reading sources.

The evidence for the Little Ice Age, the most important fluctuation in global climate in historical times, is most dramatically represented by the advance of mountain glaciers in the sixteenth and seventeenth centuries and their retreat since about 1850. The effects on the landscape and the daily life of people have been particularly apparent in Norway and the Alps. This major book places an extensive body of material relating to Europe, in the form of documentary evidence of the history of the glaciers, their portrayal in paintings and maps, and measurements made by scientists and others, within a global perspective. It shows that the glacial history of mountain regions all over the world displays a similar pattern of climatic events. Furthermore, fluctuations on a comparable scale have occurred at intervals of a millennium or two throughout the last ten thousand years since the ice caps of North America and northwest Europe melted away. This is the first scholarly work devoted to the Little Ice Age, by an author whose research experience of the subject has been extensive. This book includes large numbers of maps, diagrams and photographs, many not published elsewhere, and very full bibliographies. It is a definitive work on the subject, and an excellent focus for the work of economic and social historians as well as glaciologists, climatologists, geographers, and specialists in mountain environment.

This book pulls together major critiques of contemporary attempts to explain nature-society relations in an environmentally deterministic way. After defining key terms, it reviews the history of environmental determinism's rise and fall within geography in the early twentieth century. It discusses the key reasons for the doctrine's rejection and presents alternative, non-deterministic frameworks developed within geography for analyzing the roles played by the environment in human affairs. The authors examine the rise in recent decades of neo-deterministic approaches to such issues as the demarcation of regions, the causes of civilizational collapse in prehistory, today's globally uneven patterns of human well-being, and the consequences of human-induced climate change. In each case, the authors draw on the insights and approaches of geography, the academic discipline most conversant with the interactions of society and environment, to challenge the widespread acceptance that such approaches have won. The book will appeal to those working on human-environmental research, international development and global policy initiatives.

Through stories of diverse landscapes from around the world, this book captures human cultures and their land use practices in the environments they inhabit. The chapters cover topics from heritage in the 21st Century, appreciating and safeguarding values while facing challenges wrought by change. This title will lead readers through fascinating stories of landscapes and people. We learn of the physical and spiritual structure of rice terraces of the Honghe Mountains in China maintained by following a 1300 year sustainable practice of water allocation, while the colonial tea plantations of the Sri Lankan highlands are managed by Indian Tamils who now seek tourism as a means of additional income. Sustainable agricultural methods in the USA are being introduced to prevent landscape loss while in Australia a challenge confronting family farms is progressing to rural industrialisation. Challenges are further outlined in the mythical story of Finland's Saint Henrik pilgrimage and in the intangible Ui-won gardens of Korea. The huge challenge for Japan's landscapes is the legacy from fierce natural 21st Century disasters while in Australia's Dampier Archipelago, an avoidable yet brutal development on a unique Aboriginal rock sculptured landscape highlights serious concerns about heritage governance. These remarkable stories of landscapes and their management are inseparable from the communities that inhabit them. This book was originally published as a special issue of Landscape Research.

The Mekong Basin in Southeast Asia is one of the largest international river basins in the world. Its abundant natural resources are shared by six riparian countries and provide the basis for the livelihoods of more than 75 million people. However, ongoing socio-economic growth and related anthropogenic interventions impact the region's ecosystems, and there is an urgent need for the monitoring of the basin's land surface dynamics. Remote sensing has evolved as a key tool for this task, allowing for up-to-date analyses and regular monitoring of environmental dynamics beyond physical or political boundaries and at various temporal and spatial scales. This book serves as a forum for remote-sensing scientists with an interest in the Mekong River Basin to present their recent basin-related works as well as applied case studies of the region. A broad range of sensors from high to medium resolution, and from multispectral to SAR systems, are applied, covering topics such as land cover/land use classification and comparison, time series analyses of climate variables, vegetation structure and vegetation productivity, as well as studies on flood mapping or water turbidity monitoring. This book was originally published as a special issue of the International Journal of Remote Sensing.

This book is a state-of-the-art review of the physical, chemical and mineralogical properties of anthropogenic soils, their genesis morphology and classification, geocultural setting, and strategies for reclamation, revitalization, use and management.

In August 2007 a Russian flag was planted under the North Pole during a scientific expedition triggering speculation about a new scramble for resources beneath the thawing ice. But is there really a global grab for Polar territory and resources? Or are these activities vastly exaggerated? In this rich and wide-ranging book, Klaus Dodds and Mark Nuttall look behind the headlines and hyperbole to reveal a complex picture of the so-called scramble for the poles. Whilst anxieties over the potential for conflict and the destruction of what is often perceived as the world's last wildernesses have come to dominate Polar debates and are, to some extent, justified, their study also highlights longer historical and geographical patterns and processes of human activity in these remote territories. Over the past century, Polar landscapes have been probed, drilled, fished, tested on and dug up, as their indigenous populations have struggled to protect their rights and interests. No longer remote places, or themselves 'poles apart' from one another, the contemporary geopolitics of the Polar regions has lessons for us all as we confront a warming world where access to resources is a concern for states, big and small.

This book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation and reclamation. It also focuses on how to utilize the potential of arid lands with the minimum manipulation and alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in Iran, but around the world, and mismanagement and inappropriate exploitation of these areas may lead to further gradual degradation. As such, an understanding of the characteristics of these areas is vital if they are to be conserved and reclaimed.

Major changes are taking place in the Chinese countryside as China rushes to modernizes and urbanizes its rural fabric. The transformation is improving the quality of life of rural inhabitants, but also brings about challenges as people strive to adjust. This book systematically examines the impact of change on the daily lives and activities of the residents of Sichuan Province, in China's South-west. It examines the themes of infrastructure, transport modes and preferences, sanitation, water conservation, earthquake and flood disaster preparedness, and the impact these have on villager behavior and quality of life. This book is an essential reference guide for graduate students and practitioners in the fields of rural planning, renewal, and construction.

The Russian Far North is immensely rich in resources, both energy and other resources, and is also one of the least developed regions of Russia. This book presents a comprehensive overview of the region. It examines resource issues and the related environmental problems, considers the Arctic and the problems of sea routes, maritime boundaries and military build-up, assesses economic development, and considers the ethnic peoples of the region and also cultural and artistic subjects. Overall, the book provides a rich appraisal of how the region is likely to develop in future.

This book provides a comprehensive overview of emerging challenges facing different social groups, policy-makers and the international community related to economic growth, social development and environmental change, social inclusion and regional development. The book undertakes a critical assessment of the tensions associated with the failures of mainstream regulatory approaches and impacts of social and economic policies whilst widening the discussion on the interface between the expansion of the socio-environmental demands, equity and justice. These are crucial challenges, of great importance today and of equal relevance to the Global North and South. The book explores one of the main contradictions of development, the simplification of assessments and narrow consideration of alternatives. Taking this dilemma as its departure point, it goes on to examine the justification, trends and limitations of Western-based development and possible alternatives to fundamentally modify the basis and the rationale of the development process. It considers theoretical and lived experiences of development, paying attention to multiple scales, local realities and economic frontiers. Contributing authors explore policy recommendations and discuss effective practical tools for determining the values different people hold for ecosystem services and territorial resources. They cover the monitoring of change in the provision of ecosystem services that might increase the well-being of vulnerable groups as well as strategies to promote innovation and integrated, equitable and sustainable development.

Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.

Landscapes are being degraded and simplified across the globe. This book explores how forest restoration might be carried out to increase landscape heterogeneity, improve ecological functioning and restore ecosystem services in such landscapes. It focuses on large, landscape-scale reforestation because that is the scale at which restoration is needed if many of the problems that have now developed are to be addressed. It also shows how large-scale forest restoration might improve human livelihoods as well as improve conservation outcomes. A number of governments have undertaken national reforestation programs in recent years; some have been more successful than others. The author reviews these to explore what type of reforestation should be used, where this should be carried out and how much should be done. For example, are the traditional industrial forms of reforestation necessarily the best to use in all situations? How can forest restoration be reconciled with the need for food security? And, are there spatial thresholds that must be exceeded to generate economic and environmental benefits? The book also examines the policy and institutional settings needed to encourage large-scale reforestation. This includes a discussion of the place for incentives to encourage landholders to undertake particular types of reforestation and to reforest particular locations. It also considers forms of governance that are likely to lead to an equitable sharing of the costs and benefits of forest restoration.

Water scarcity is an increasing problem in many parts of the world, yet conventional supply-side economics and management are insufficient to deal with it. In this book the role of water trading as an instrument of integrated water resources management is explored in depth. It is also shown to be an instrument for conflict resolution, where it may be necessary to reallocate water in the context of increasing scarcity. Recent experiences of implementation in different river basins have shown their potential as instruments for improving allocation. These experiences, however, also show that there are implementation challenges and some limitations to trading that need to be considered. This book explores the various types of water trading formulas through the experience of using them in different parts of the world. The final result is varied because, in most cases, trading is conditioned by the legal and institutional framework in which the transactions are carried out. The role of government and the definition of water rights and licenses are critical for the success of water trading. The book studies the institutional framework and how transactions have been undertaken, drawing some lessons on how trading can improve. It also analyses whether trading has really been a positive instrument to manage scarcity and improve water ecosystems and pollution emission problems in those parts of the world which are most affected. The book concludes by making policy proposals to improve the implementation of water trading.

The Nile River and its basin extend over a distinctive geophysical cord connecting eleven sovereign states from Egypt to Tanzania, which are home to an estimated population of 422.2 million people. The Nile is an essential source of water for domestic, industrial and agricultural uses throughout the basin, yet for more than a century it has been at the centre of continuous and conflicting claims and counter-claims to rights of utilization of the resource. In this book the author examines the multifaceted legal regulation of the Nile. He re-constructs the legal and historical origin and functioning of the British Nile policies in Ethiopia by examining the composition of the Anglo-Ethiopian Treaty of 1902, and analyses its ramifications on contemporary riparian discourse involving Ethiopia and Sudan. The book also reflects on two fairly established legal idioms - the natural and historical rights expressions - which constitute central pillars of the claims of downstream rights in the Nile basin; the origin, essence and legal authority of the notions has been assessed on the basis of the normative dictates of contemporary international watercourses law. Likewise, the book examines the non-treaty based claims of rights of the basin states to the Nile waters, setting out what the equitable uses principle entails as a means of reconciling competing riparian interests, and most importantly, how its functioning affects contemporary legal settings. The author then presents the concentrated diplomatic movements of the basin states in negotiations on the Transitional Institutional Mechanism of the Nile Basin Initiative (NBI) - pursued since the 1990's, and explains why the substance of water use rights still continued to be perceived diversely among basin states. Finally, the specific legal impediments that held back progress in negotiations on the Nile Basin Cooperative Framework are presented in context.

Marine Spatial Planning (MSP) is an integrated and comprehensive approach to ocean governance and is used to establish a rational use of marine space and reconcile conflicting interests of its users. MSP allows both a high level of environmental protection and a wide range of human activities and emphasizes coordinated networks of national, regional and global institutions. This book focuses on the framework of international law behind MSP and especially on the transboundary aspects of MSP. It first sets out a general framework for transboundary MSP and then moves on to compare and assess differences and similarities between different regions. Specific detailed case studies include the EU with the focus on the Baltic Sea and North Sea, the Bay of Bengal and Great Barrier Reef in Australia. The authors examine the national and regional significance of MSP from an integrated and sustainable ocean governance point of view. They also show how transboundary MSP can create opportunities and positive initiatives for cross-border cooperation and contribute to the effective protection of the regional marine environment.

The key aim of this book is to explore the global conservation and management of sharks. There has been a rapid decline in populations of many shark species, while new science has emerged of the critical role they play in marine ecosystems. However, the authors show that conservation law and policy have been slow to develop, with only a small number of iconic species being protected worldwide. The increase in fishing impact - primarily through shark finning and by-catch - has led to shark conservation receiving greater international attention in recent years. The book explores our current knowledge and status of the law and science in relation to sharks with a particular focus on improving frameworks for their conservation and management. Recent trends are analysed, including shark finning bans that have been put in place in several countries, the widening number of nations establishing shark sanctuaries and the growth of shark-based tourism. The efficacy of current listing processes for endangered species and fisheries regulations is also examined. Tourism is explored as an alternative to fishing and the risks and impacts associated with this industry are analysed. Contributors include leading authorities from universities and conservation organizations in North America, Europe and Australia. A common theme is to emphasise the importance of collaborative governance between various interest groups and the need for inter-disciplinary research and management approaches that are necessary to address the decline in sharks.

Fingerponds are earthen ponds dug at the edge of natural wetlands and stocked naturally with wild fish during flooding. They preserve the wetland environment in which they are situated while maintaining a productive culture system. In this study, the importance of organic manure applications in enhancing nutrient levels, phytoplankton and periphyton productivities and ultimately fish production was examined in experimental Fingerponds set up with the participation of local communities in Uganda. Results show that organic manures enhance algal development and fish production in Fingerponds, but close monitoring and control are needed. Fish yields in Fingerponds can be enhanced to 1500 - 2800 kg/ha over a functional period of 200 to 300 days using animal manure (e.g. chicken), fermented green manure and artificial substrates for periphyton development. Good management practices are required to regulate pond inputs and conditions. High clay turbidity, nitrogen limitation and high recruitment of fish can limit fish production. Overall, Fingerponds were shown to be an effective addition to protein production for poor riparian communities in East Africa and are recommended for adoption.
