Peri-urban futures: Scenarios and models for land use change in Europe

by Carmen Aalbers Kjell Nilsson Simon Bell Stephan Pauleit Thomas A. Sick Nielsen

Presently, peri-urbanisation is one of the most pervasive processes of land use change in Europe with strong impacts on both the environment and quality of life. It is a matter of great urgency to determine strategies and tools in support of sustainable development. The book synthesizes the results of PLUREL, a large European Commission funded research project (2007-2010). Tools and strategies of PLUREL address main challenges of managing land use in peri-urban areas. These results are presented and illustrated by means of 7 case studies which are at the core of the book. This volume presents a novel, future oriented approach to the planning and management of peri-urban areas with a main focus on scenarios and sustainability impact analysis. The research is unique in that it focuses on the future by linking quantitative scenario modeling and sustainability impact analysis with qualitative and in-depth analysis of regional strategies, as well as including a study at European level with case study work also involving a Chinese case study.

Peri-urban Water and Sanitation Services

by Mathew Kurian Patricia Mccarney

More than 2.6 billion people in the developing world lack access to safe water and sanitation service. The Millennium Development Goal's (MDG) target is to halve the number of people without access to a sustainable source of water supply and connection to a sewer network by 2015. That target is unlikely to be met. If there is anything that can be learnt from European experience it is that institutional reform occurs incrementally when politically enfranchised urban populations perceive a threat to their material well-being due to contamination of water sources.

Peridynamics and Its Applications Using Ansys

by Yanan Zhang Erdogan Madenci Sundaram Vinod Anicode

This book introduces a unified implementation of bond- and state-based peridynamic theory (PD) within a commercial finite element framework, Ansys, utilizing its native elements. It details the implementation of the PD theory and its integration with traditional finite elements. The primary objective is to equip students, researchers, and practicing engineers with both theoretical and practical knowledge of the PD theory, along with the skills necessary for analyzing engineering problems using Ansys. The book demonstrates that, unlike the conventional finite element method (FEM), the PD theory is highly suitable for progressive failure analysis, the multi-scale analysis of materials involving fracture and failure, and multi-physics analysis, including electromigration, corrosion, and electrodeposition. Additionally, it provides a step-by-step illustration of the specific procedures in the pre-processing, solution, and post-processing phases of the analysis through the Graphical User Interface (GUI) for various applications. The book is designed to be introductory and self-contained, minimizing the need for additional reference material.

Periglacial Landscapes of Europe

by Marc Oliva Daniel Nývlt José M. Fernández-Fernández

This book comprehensively presents the geography of landforms linked to periglacial processes across Europe. The landscape of the European cold climate regions, both at high latitudes and in mountainous environments, represent the lingering, minimal expression of the glaciers. In addition, periglacial elements can be found in temperate regions, where temperatures no longer favor periglacial processes, so landforms are therefore inherited from previous cold phases.The book is divided into five parts: an introductory section on climate variability responsible for periglacial dynamics across Europe; a second part including 3 blocks on periglacial landforms in southern, central and northern Europe; and a final chapter providing a more general perspective on the impact of periglacial processes on the landscape of Europe. The book offers a valuable reference guide for scientists from all disciplines interested in cold climate processes, as well as readers outside academia (territorial managers, environmentalists, mountaineers, politicians, engineers, etc.).

Periglacial Preconditioning of Debris Flows in the Southern Alps, New Zealand

by Katrin Sattler

This thesis represents one of the few studies so far that systematically analyses environmental conditions within debris flow source areas to determine their relative importance for debris flow development. Environmental site conditions, such as slope gradient and debris availability, influence the spatial and temporal distribution of debris flows in high-alpine areas. However, current understanding of these preconditioning controls is mostly qualitative and inadequate for debris-flow hazard assessments and climate change impact studies. The author's research investigates the role of frost weathering and permafrost in the occurrence of debris flows in the Southern Alps of New Zealand. Analyses are based on an extensive debris flow inventory, documenting debris flow occurrence and activity over the last 60 years in selected catchments. Debris flow activity is compared to frost-weathering intensity estimates from two models, allowing the practical comparison of two competing frost-weathering hypotheses currently discussed in literature. Information on permafrost occurrence is based on a new distributed permafrost estimate for the Southern Alps, derived from climatic conditions at active rock glacier sites. This pioneering thesis provides empirical evidence that frost weathering promotes debris-flow formation. It further highlights the potential and limitations of regional-scale studies for advancing our understanding of debris-flow preconditioning factors.

Periodic Monopoles and Difference Modules (Lecture Notes in Mathematics #2300)

by Takuro Mochizuki

This book studies a class of monopoles defined by certain mild conditions, called periodic monopoles of generalized Cherkis–Kapustin (GCK) type. It presents a classification of the latter in terms of difference modules with parabolic structure, revealing a kind of Kobayashi–Hitchin correspondence between differential geometric objects and algebraic objects. It also clarifies the asymptotic behaviour of these monopoles around infinity.The theory of periodic monopoles of GCK type has applications to Yang–Mills theory in differential geometry and to the study of difference modules in dynamical algebraic geometry. A complete account of the theory is given, including major generalizations of results due to Charbonneau, Cherkis, Hurtubise, Kapustin, and others, and a new and original generalization of the nonabelian Hodge correspondence first studied by Corlette, Donaldson, Hitchin and Simpson.This work will be of interest to graduate students and researchers in differential and algebraic geometry, as well as in mathematical physics.

Perishability Fatigue: Forays Into Environmental Loss and Decay (Critical Life Studies)

by Vincent Bruyere

The Svalbard Global Seed Vault project is an arctic archive designed to preserve the world’s agricultural biodiversity. What do it and other novel forms of storage tell us about our relationship to the future in a time of resource depletion and extinction scenarios? In this innovative book, Vincent Bruyere offers an invitation to look at the present we live in through a fresh lens: the difference between storage and burial in the age of sustainability science.Perishability Fatigue considers questions of permanence and the potentiality of retrieval, noting the tensions within our collective sense of time and finitude. Bruyere reflects on the nature and significance of perishability, asking what it means to have one’s sense of temporality engendered by seed banks and frozen embryo storage, genetically modified organisms and the “de-extinction” of species, nuclear-waste repositories, oncology, and palliative care. He draws attention to the scripts and scenarios that mediate our relations to loss and decay, preservation and conservation, emphasizing the inequalities implicit in technologies of perishability, which promise continuity in the future to some while refusing it to others. A highly interdisciplinary study, Perishability Fatigue reframes the environmental humanities and humanistic inquiry into sustainability science by developing a new language to commemorate fatigue and transience in a culture of preparedness and survival.

Perma/Culture: Imagining Alternatives in an Age of Crisis (Routledge Environmental Humanities)

by Molly Wallace and David Carruthers

In the face of what seems like a concerted effort to destroy the only planet that can sustain us, critique is an important tool. It is in this vein that most scholars have approached environmental crisis. While there are numerous texts that chronicle contemporary issues in environmental ills, there are relatively few that explore the possibilities and practices which work to avoid collapse and build alternatives. The keyword of this book’s full title, 'Perma/Culture,' alludes to and plays on 'permaculture', an international movement that can provide a framework for navigating the multiple 'other worlds' within a broader environmental ethic. This edited collection brings together essays from an international team of scholars, activists and artists in order to provide a critical introduction to the ethico-political and cultural elements around the concept of ‘Perma/Culture’. These multidisciplinary essays include a varied landscape of sites and practices, from readings from ecotopian literature to an analysis of the intersection of agriculture and art; from an account of the rewards and difficulties of building community in Transition Towns to a description of the ad hoc infrastructure of a fracking protest camp. Offering a number of constructive models in response to current global environmental challenges, this book makes a significant contribution to current eco-literature and will be of great interest to students and researchers in Environmental Humanities, Environmental Studies, Sociology and Communication Studies.

Permaculture: A Spiritual Approach

by Craig Gibsone Jan Martin Bang

Permaculture design as divine creative activity. Permaculture looks for the patterns embedded in our natural world as inspirations for designing solutions to the many challenges we are presented with today. It is a philosophical, spiritual and practical approach to the use of the land, integrating microclimate, functional plants, animals, soils, water management and human needs into intricately connected, highly productive systems. In essence, permaculture uses observation as basis for creating sustainable and effective human settlements. The authors discuss the components Earthshare, Fairshare and Peoplecare, with a specific emphasis on the spiritual aspects of the design process. Topics range from soil and plants, energy sources and house design to alternative economics, group process, governance, and spiritual nurturing and enquiry. Examples of existing permaculture structures from around the world, most notably from the Findhorn Community Eco-Village, bring the concepts to life. First-hand accounts of how people got started on their permaculture project lend a personal touch. The first book to look at the spiritual aspects as well as the practical implementation of permaculture design.

The Permaculture City

by Toby Hemenway

Permaculture is more than just the latest buzzword; it offers positive solutions for many of the environmental and social challenges confronting us. And nowhere are those remedies more needed and desired than in our cities. The Permaculture City provides a new way of thinking about urban living, with practical examples for creating abundant food, energy security, close-knit communities, local and meaningful livelihoods, and sustainable policies in our cities and towns. The same nature-based approach that works so beautifully for growing food--connecting the pieces of the landscape together in harmonious ways--applies perfectly to many of our other needs. Toby Hemenway, one of the leading practitioners and teachers of permaculture design, illuminates a new way forward through examples of edge-pushing innovations, along with a deeply holistic conceptual framework for our cities, towns, and suburbs. The Permaculture City begins in the garden but takes what we have learned there and applies it to a much broader range of human experience; we're not just gardening plants but people, neighborhoods, and even cultures. Hemenway lays out how permaculture design can help towndwellers solve the challenges of meeting our needs for food, water, shelter, energy, community, and livelihood in sustainable, resilient ways. Readers will find new information on designing the urban home garden and strategies for gardening in community, rethinking our water and energy systems, learning the difference between a "job" and a "livelihood," and the importance of placemaking and an empowered community. This important book documents the rise of a new sophistication, depth, and diversity in the approaches and thinking of permaculture designers and practitioners. Understanding nature can do more than improve how we grow, make, or consume things; it can also teach us how to cooperate, make decisions, and arrive at good solutions.

The Permaculture Promise: What Permaculture Is and How It Can Help Us Reverse Climate Change, Build a More Resilient Future on Earth, and Revitalize Our Communities

by Toby Hemenway Jono Neiger

Permaculture is a sustainability buzzword, but many people wonder what it actually means and why it is relevant. Originally coined by combining the words permanent and agriculture, permaculture has evolved into an optimistic approach connecting all the systems of human life: gardening, housing, transportation, energy, and how we structure our communities. The Permaculture Promise explains in simple terms why permaculture may be the key to unlocking a livable future on our planet. Author Jono Neiger asserts that humans can thrive while simultaneously making Earth healthier and not destroying it. The book shows 22 ways that permaculture can create a better future for all living things. Profiles of people and communities — including an urban dweller who tore up her driveway to create a vegetable garden and a California housing development that dedicates a third of its land to parks, orchards, and gardens — will inspire you to incorporate permaculture principles into your life today.

The Permaculture Way

by Graham Bell

The Permaculture Way shows us how to consciously design a lifestyle which is low in environmental impact and highly productive. It demonstrates how to meet our needs, make the most of resources by minimizing waste and maximizing potential, and still leave the Earth richer than we found it.

Permafrost Ecosystems

by Akira Osawa Olga A. Zyryanova Takuya Kajimoto Yojiro Matsuura Ross W. Wein

Drawing from a decade-long collaboration between Japan and Russia, this important volume presents the first major synthesis of current knowledge on the ecophysiology of the coniferous forests growing on permafrost at high latitudes. It presents ecological data for a region long inaccessible to most scientists, and raises important questions about the global carbon balance as these systems are affected by the changing climate. Making up around 20% of the entire boreal forests of the northern hemisphere, these 'permafrost forest ecosystems' are subject to particular constraints in terms of temperature, nutrient availability, and root space, creating exceptional ecosystem characteristics not known elsewhere. This authoritative text explores their diversity, structure, dynamics and physiology. It provides a comparison of these forests in relation to boreal forests elsewhere, and concludes with an assessment of the potential responses of this unique biome to climate change. The book will be invaluable to advanced students and researchers interested in boreal vegetation, forest ecology, silviculture and forest soils, as well as to researchers into climate change and the global carbon balance.

The Permafrost Environment (Routledge Revivals)

by Stuart A. Harris

Originally published in 1986, The Permafrost Environment examines how the search for oil, gas and minerals in the arctic region instigated new and vitally important needs to understand the permafrost environment. The construction of roads, airfields, buildings and pipelines in this inhospitable environment has posed enormous problems for engineers and geologists. This book is a comprehensive review of the nature of the permafrost environment and its utilization. It looks at environmental processes and their effects and examines the management problems which result. It provides a detailed look at how normal procedures for construction etc. need to be modified to cope with the special conditions and it gives examples from throughout the arctic region, including Canada, Siberia, Alaska, Greenland and Northern Scandinavia.

Permafrost Hydrology

by Ming-Ko Woo

Permafrost Hydrology systematically elucidates the roles of seasonally and perennially frozen ground on the distribution, storage and flow of water. Cold regions of the World are subject to mounting development which significantly affects the physical environment. Climate change, natural or human-induced, reinforces the impacts. Knowledge of surface and ground water processes operating in permafrost terrain is fundamental to planning, management and conservation. This book is an indispensable reference for libraries and researchers, an information source for practitioners, and a valuable text for training the next generations of cold region scientists and engineers.

Permafrost in Canada

by Roger J.E. Brown

Permafrost is the thermal condition of the earth's crust when its temperature has been below 32°F continuously for a number of years. Half of Canada's land surface lies in the permafrost region--either in the continuous zone where the ground is frozen to a depth of hundreds of feet, or in the discontinuous zone where permafrost is thinner, and there are areas of unfrozen ground.The existence of permafrost causes problems for the development of the northern regions of all countries extending into the Arctic. Mining operations are hindered by frozen ore which resists blasting and is difficult to thaw. Agriculture is restricted by the presence of permafrost near the ground surface which limits the soil available for plant growth. Engineering structures are also affected by the low temperatures. Ice layers give soil a rock-like structure with high strength. However heat transmitted by buildings often causes the ice to melt, and the resulting slurry is unable to support the structure. Many settlements in northern Canada have examples of structural damage or failure caused by permafrost. In the construction and maintenance of railways, buildings, water and sewage lines, dams, roads, bridges, and airfields, normal techniques must often be modified at additional cost because of permafrost.For the last twenty-five years scientific investigations and engineering projects have increased steadily in Canada's permafrost region, and it is now technically possible to build any structure or conduct any activity on the worst soils and under permafrost conditions.This comprehensive analysis of permafrost--its origin, definition, and occurrence, and the effect it has on industry and agriculture--will be invaluable to the growing number of people working in the north and to those interested in its development.

Permeable Reactive Barrier: Sustainable Groundwater Remediation (Advances in Trace Elements in the Environment #1)

by Ravi Naidu

Remediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks them down. And although this approach is gaining popularity, there are few references available on the subject. Until now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides. The text also examines implementation stages such as the initial feasibility assessment, laboratory treatability studies (including column studies), estimation of PRB design parameters, and development of a long-term monitoring network for the performance evaluation of the barrier. It also outlines the predictive tools required for life cycle analysis and cost/performance assessment. A review of current PRB technology and its applications, this book includes case studies that exemplify the concepts discussed. It helps you determine when to recommend PRB, what information is needed from the site investigation to design it, and what regulatory validation is required.

Permeation Grouting for Liquefaction Countermeasures: Implementation and Performance Evaluation

by Yoshihisa Sugimura Kiyonobu Kasama

Academic and industry experts describe the use of chemical (permeation) grouting beneath an airport runway to improve ground resistance to liquefaction. They present the cost, environmental, and operational benefits; specifications; methodology; and practical results of this cutting-edge method. Because transportation infrastructure such as ports and airports are required to operate even in the event of a large earthquake, they must be resilient against liquefaction.Through contributions from experts in academia and industry, this book describes the discovery of construction defects at three airports in Japan and the subsequent project to repair and strengthen the ground using chemical grouting using environmentally friendly colloidal silica, the first time this technique was used in Japan. This book first describes chemical grouting and its benefits, its specifications, and field investigation results of its ground improvement performance. Next, it demonstrates a numerical and probabilistic method to model spatial variability in material properties of field data on improved ground. Finally, it explains a performance-based verification for airport runway availability in terms of bearing capacity and runway flatness after a large earthquake. Through its clear explanations, this book enables readers to implement chemical grouting and enjoy the cost, environmental, access, and operational benefits of this technique over traditional methodologies that would require temporary site closure and large-scale excavation. Because the concept and methodology described in this book are applicable to various geological, geotechnical, and seismological conditions depending on the location and structural and operational conditions depending on the infrastructure type, this book is a useful resource for geotechnical and other infrastructure engineers who must strengthen the ground without disrupting normal operations.

Permit Trading in Different Applications (Routledge Explorations In Environmental Economics #33)

by Bernd Hansjürgens Ralf Antes Marianne Strunz

Permit trading is an environmental policy instrument that has received increasing levels of attention over recent years. Coming from the field of air quality management, with the European CO2 emissions trading system being the most prominent example, it enters new fields of application, such as land use policy and biodiversity protection, water quality and water quantity trading. This book gives an overview of these recent developments and discusses the possibilities and limits of permit trading in environmental policies. The advantages of permit trading are not only seen with respect to economic efficiency, which leads to achieving the environmental target at minimum cost, but also with respect to the instrument’s environmental effectiveness. By setting a cap for the overall emissions, a given environmental target can be met. This makes permit trading an interesting case for many environmental fields where safeguarding the environmental target plays a dominant role. Against this background, permit trading is discussed in environmental policy fields, where it has not been considered before, for example, land use management, biodiversity protection and water trading. Permit Trading in Different Applications analyses the properties of permit trading: its possibilities and limitations, its design options and its restrictions on a more general level. It demonstrates how lessons learnt in established policy fields like air quality management can be transferred to new and emerging fields of application. This collection will provide students and practitioners in environmental sciences and policy with valuable research into instrument choice and design with respect to permit trading.
