The efficient use of natural resources is key to a sustainable economy, and yet the complexities of the physical aspects of resource efficiency are poorly understood. In this challenging book, the author proposes a major advance in our understanding of this topic by analysing resource efficiency and efficiency gains from the perspective of common pool resources, applying this idea particularly to water resources and its use in irrigated agriculture. The author proposes a novel concept of "the paracommons", through which the savings of increased resource efficiency can be viewed. In effect he asks; "who gets the gain of an efficiency gain?" By reusing, economising and avoiding losses, wastes and wastages, freed up resources are available for further use by four 'destinations'; the same user, parties directly connected to that user, the wider economy or returned to the common pool. The paracommons is thus a commons of - and competition for - resources salvaged by changes to the efficiency of natural resource systems. The idea can be applied to a range of resources such as water, energy, forests and high-seas fisheries. Five issues are explored: the complexity of resource use efficiency; the uncertainty of efficiency interventions and outcomes; destinations of freed up losses, wastes and wastages; implications for resource conservation; and the interconnectedness of users and systems brought about by efficiency changes. The book shows how these ideas put efficiency on a par with other dimensions of resource governance and sustainability such as equity, justice, resilience and access.
The TransNav 2011 Symposium held at the Gdynia Maritime University, Poland in June 2011 has brought together a wide range of participants from all over the world. The program has offered a variety of contributions, allowing to look at many aspects of the navigational safety from various different points of view. Topics presented and discussed at the Symposium were: navigation, safety at sea, sea transportation, education of navigators and simulator-based training, sea traffic engineering, ship's manoeuvrability, integrated systems, electronic charts systems, satellite, radio-navigation and anti-collision systems and many others. This book is part of a series of six volumes and provides an overview of Problems in Maritime Navigation, Transport and Shipping and is addressed to scientists and professionals involved in research and development of navigation, safety of navigation and sea transportation.
A hydroinformatics system represents an electronic knowledge encapsulator that models part of the real world and can be used for the simulation and analysis of physical, chemical and biological processes in water systems, in order to achieve a better management of the aquatic environment. Thus, modelling is at the heart of hydroinformatics. The theory of nonlinear dynamics and chaos, and the extent to which recent improvements in the understanding of inherently nonlinear natural processes present challenges to the use of mathematical models in the analysis of water and environmental systems, are elaborated in this work. In particular, it demonstrates that the deterministic chaos present in many nonlinear systems can impose fundamental limitations on our ability to predict behaviour, even when well-defined mathematical models exist. On the other hand, methodologies and tools from the theory of nonlinear dynamics and chaos can provide means for a better accuracy of short-term predictions as demonstrated through the practical applications in this work.
Desertification, land degradation and other geological hazards have resulted from the remobilization of dune areas and climatic change. Recent developments in satellite images of deserts, orbital images of Mars and Venus, and oil and gas discoveries in ancient dunes, have significantly advanced our understanding of desert environments. "The Geomorphology of Desert Dunes" explores how desert dunes are formed, how they change and their environmental importance. Drawing on extensive research from the deserts of South Africa, North America, India, Northern Europe and Australia, the author analyses dune types, patterns, sand seas and sediments, and investigates dune dynamics and processes at different temporal and spatial scales. Investigating the role of climatic change, the author concludes that a better understanding of dune processes and dynamics is vital for effective and appropriate mitigation of environmental problems in arid regions.
Living with the Wayapi, and their charismatic leader Waiwai, is a
serious adventure. It is demanding, and can turn dangerous in a
moment. The environment is a difficult one, but beautiful and
baffling in its richness. And the job of learning about the people
is like a journey without end.
We live in a world that is increasingly vulnerable to climatic shocks - affecting agriculture and industry, government and international trade, not to mention human health and happiness. Serious anxieties have been aroused by scientists warning of dire perils that could result from upsets of the climatic regime. In this book, Hubert Lamb examines what we know about climate, how the past record of climate can be reconstructed, the causes of climatic variation, and its impact on human affairs now, and in the historical and prehistoric past. This second edition includes a new Preface and Postscript reviewing the new literature of recent years, and discusses implications for a deeper understanding of the problems of future climatic fluctuations and forecasting.

The world's forests are disappearing at an alarming rate, and with disastrous consequences. Demand for wood and paper products ranks high amongst the causes of deforestation and forest degradation, and is now the major cause of loss in those forests richest in wildlife. There is a great deal to be done to improve the timber industry before our forests are safely and sustainably managed. Bad Harvest presents an incisive account of the role that the timber trade has played in the loss and degradation of forests around the world. It examines the environmental consequences of the trade on boreal, temporal and tropical regions, and its impacts for local people working and living in the forests. It also looks at the changing nature of the trade, and assesses current national and international initiatives to address the impacts of deforestation. Finally, the authors show how things could be improved in the future, by presenting a new strategy for sustainable forest management. Based on 15 years of extensive research - particularly work carried out by the World Wide Fund for Nature - Bad Harvest is essential reading on the subject; not only for environmentalists, but also for those in the timber trade seeking to improve the management and reputation of their product.
The third edition of this classic text, presents a broad-based study of the variations in the form and functioning of the biosphere at regional and global scale.
Most government agencies and private companies are investing significant resources in the production and use of geographical data. The capabilities of Geographical Information Systems (GIS) for data analysis are also improving, to the extent that the potential performance of GIS software and the data available for analysis outstrip the abilities of managers and analysts to use and analyze the information. This is especially true for environmental applications. Here the need to keep up-to-date is essential for providing effective and efficient services. Environmental Modeling with GIS and Remote Sensing derives from a training course run by ITC for professionals and managers in the environmental sciences, detailing the applications of remote sensing and GIS for environmental modeling and assessment. It sets out the current research results and provides operational methods for environmental mapping and monitoring.
As coastal populations burgeon, problems of erosion, pollution and coastal change are becoming ever more serious and necessitate scientifically informed management strategies. This authoritative new study discusses the causes of, and possible solutions to, some of the more pressing problems at the coast, against a background of the natural geomorphological and ecological workings of coastal environments.A holistic approach to the understanding of coastal problems is suggested, which integrates geomorphology, ecology and society through a consideration of the basic processes at work. Coastal problems are caused by both human and natural impacts, often working in conjunction with each other; thus drawing on their wide experience of temperate and tropical coasts the authors consider all types of coastal problems, ranging from those produced entirely naturally to those where the human impact dominates. Extensive use is made of case studies drawn from around the world, from beach erosion along the Nigerian coast to the recovery of the Vietnamese mangroves from war damage. A major theme of the book is that, given recent downgrading of predictions of future sea level rise, it is the distinctive geomorphological, ecological and societal aspects of each coast which are the vital factors.'Coastal Problems' brings together material vital to any attempts to understand and manage our coasts and will be of interest to all those concerned with the environment and its management.
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.
Mountain environments, once thought hostile, now attract major
economic investments for tourism, hydro-power and communication
routes. As change and technology works its way around the world,
the fight between ecology and dollars will doubtless escalate.
The world's coastlines represent a myriad of dynamic and constantly changing environments. Heavily settled and intensely used areas, they are of enormous importance to humans and understanding how they are shaped and change is crucial to our future.Introduction to Coastal Processes and Geomorphologybegins by discussing coastal systems and shows how these systems link to the processes examined in detail throughout the book. These include the morphodynamic paradigm, tides, waves and sediment transport. Later chapters explore fluvial deltas, estuaries, beaches and barriers, coastal sand dunes and geologically-influenced coasts such as cliffs, coral reefs and atolls. A new chapter addresses the forward-facing aspect of coastal morphodynamics, including the ways in which coasts respond to rapid climate changes such as present day global warming. Also new to this second edition is a chapter on future coasts which considers the wider effects of coastal change on other important aspects of coastal systems, including ecology, management, socio-cultural activities, built and natural heritage, and archaeology. Case studies using examples from around the world illustrate theory in practice and bring the subject to life. Each chapter starts by outlining the 'aims' and questions at the end allow you to track your progress.
First published in 1985. This is the is the second edition of a study looking at ecology and biogeography with updated chapters including current research. It starts with the with the study of plants to gain an understanding of the complexities of ecological relationships.
This study, conducted in Kenya, gives the first insight into the performance of a constructed treatment wetland receiving pulp and paper mill wastewater in the tropics. The wetland effectively removed organic matter, suspended solids, phenols and nutrients. BOD and phenols reduction rates are reported for the first time. Design parameters and guidelines for the set-up and maintenance of a full-scale wetland are recommended. The study concludes that integrating a full-scale wetland, as a tertiary stage with the existing treatment ponds would significantly improve the quality of water in River Nzoia downstream of the effluent discharge. This is a valuable resource book for scientists, managers and students in the field of wetland ecology, water and environmental management.
In this comprehensive book, the critical components of the European landscape - forest, parkland, and other grazed landscapes with trees are addressed. The book considers the history of grazed treed landscapes, of large grazing herbivores in Europe, and the implications of the past in shaping our environment today and in the future. Debates on the types of anciently grazed landscapes in Europe, and what they tell us about past and present ecology, have been especially topical and controversial recently. This treatment brings the current discussions and the latest research to a much wider audience. The book breaks new ground in broadening the scope of wood-pasture and woodland research to address sites and ecologies that have previously been overlooked but which hold potential keys to understanding landscape dynamics. Eminent contributors, including Oliver Rackham and Frans Vera, present a text which addresses the importance of history in understanding the past landscape, and the relevance of historical ecology and landscape studies in providing a future vision.

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.
A clear, concise discussion of today's hottest topics in climate change, including adapting to climate change and geo-engineering to mitigate the effects of change, Engineering Response to Climate Change, Second Edition takes on the tough questions of what to do and offers real solutions to the practical problems caused by radical changes in the Earth's climate. From energy consumption and carbon dioxide emissions reduction, to climate-altering technologies, this new edition explores the latest concerns such as acidification of the ocean, energy efficiency, transportation, space solar power, and future and emerging possibilities. The editors set the stage by discussing the separate issues of the emissions of radiatively important atmospheric constituents, energy demand, energy supply, agriculture, water resources, coastal hazards, adaption strategies, and geo-engineering. They explain the difference between the natural and human drivers of climate change and describe how humans have influenced the global climate during past decades. Each chapter concludes with discussion questions, calculations, and possible research topics. See What's in the Second Edition: New conceptual tools and research necessary for problems associated with fossil fuels Cutting-edge topics such as adaption and geo-engineering The latest concerns such as acidification of the ocean, energy efficiency, transportation, and space solar power Solutions to problems caused by changes in the Earth's climate So much has changed in the 15 years since the publication of the first edition, that this is, in effect, a completely new book. However, the general theme is the same: the climate energy problem has become largely an engineering problem. With this in mind, the book explores what engineers can do to prevent, mitigate, or adapt to climate change.
This book describes a methodology for imputing a monetary value to the loss in beach recreational services that would result from a hypothetical oil spill in the Georges Bank area off Massachusetts. It is a valuable resource for students interested in environmental studies.
Britain's great cloak of natural forest disappeared mostly in prehistoric times. Over the passage of time and by the industrial revolution, Britain's economy had become almost entirely dependent on timber imports from abroad. Shipping blockades in the First World War meant a frantic search for woodlands that could be cut down to make vital pit props and sawn wood for wartime construction. After the war, Britain's tree cover was near to an all-time low. Only since 1919 have practical measures been taken to reverse the long history of forest decline, and a hundred years of tree planting has seen the forest cover of Britain more than double. Today, tree planting in Britain is motivated more by environmental and social concerns than purely timber production. In Woods and People, David Foot reveals the story of twentieth-century forest creation, and the eureka moment in the 1980s that challenged foresters and conservationists to work together on new ideas.
Ranging from the poverty and exploding population of Bangladesh to the dazzling technology and aging population of Japan, from the two most populous states of India and China to the tiny states of Singapore and the Maldives and to the emptiness of Siberia, Asia contains perhaps the greatest diversity of physical environments, cultures and levels of development of any of the continents. Clearly illustrated with basic maps of the countries discussed, "The Changing Geography of Asia" presents a systematic review of 25 years of development - a guide to the physical, economic, social and political environments of contemporary Asia. This book should be of interest to introductory students in geography and development studies. |
