Across the Great Divide: Explorations In Collaborative Conservation And The American West
by Daniel Kemmis Sarah F. Bates Philip Brick Donald SnowAmid the policy gridlock that characterizes most environmental debates, a new conservation movement has emerged. Known as "collaborative conservation," it emphasizes local participation, sustainability, and inclusion of the disempowered, and focuses on voluntary compliance and consent rather than legal and regulatory enforcement. Encompassing a wide range of local partnerships and initiatives, it is changing the face of resource management throughout the western United States.Across the Great Divide presents a thoughtful exploration of this new movement, bringing together writing, reporting, and analysis of collaborative conservation from those directly involved in developing and implementing the approach. Contributors examine: the failure of traditional policy approaches recent economic and demographic changes that serve as a backdrop for the emergence of the movement the merits of, and drawbacks to, collaborative decision-making the challenges involved with integrating diverse voices and bringing all sectors of society into the movement .In addition, the book offers in-depth stories of eight noteworthy collaborative initiatives -- including the Quincy Library Group, Montana's Clark Fork River, the Applegate Partnership, and the Malpai Borderlands -- that explore how different groups have organized and acted to implement their goals.Among the contributors are Ed Marston, George Cameron Coggins, David Getches, Andy Stahl, Maria Varela, Luther Propst, Shirley Solomon, William Riebsame, Cassandra Moseley, Lynn Jungwirth, and others. Across the Great Divide is an important work for anyone involved with collaborative conservation or the larger environmental movement, and for all those who care about the future of resource management in the West.

Acoustic Waves in Periodic Structures, Metamaterials, and Porous Media: From Fundamentals to Industrial Applications (Topics in Applied Physics #143)
by Noé Jiménez Olga Umnova Jean-Philippe GrobyThis book delivers a comprehensive and up-to-date treatment of practical applications of metamaterials, structured media, and conventional porous materials. With increasing levels of urbanization, a growing demand for motorized transport, and inefficient urban planning, environmental noise exposure is rapidly becoming a pressing societal and health concern. Phononic and sonic crystals, acoustic metamaterials, and metasurfaces can revolutionize noise and vibration control and, in many cases, replace traditional porous materials for these applications.In this collection of contributed chapters, a group of international researchers reviews the essentials of acoustic wave propagation in metamaterials and porous absorbers with viscothermal losses, as well as the most recent advances in the design of acoustic metamaterial absorbers. The book features a detailed theoretical introduction describing commonly used modelling techniques such as plane wave expansion, multiple scattering theory, and the transfer matrix method. The following chapters give a detailed consideration of acoustic wave propagation in viscothermal fluids and porous media, and the extension of this theory to non-local models for fluid saturated metamaterials, along with a description of the relevant numerical methods. Finally, the book reviews a range of practical industrial applications, making it especially attractive as a white book targeted at the building, automotive, and aeronautic industries.
Acoustic Investigation of Complex Seabeds (SpringerBriefs in Oceanography)
by Jacques Yves Guigné Philippe BlondelOffshore drilling and constructions require exact knowledge of the geophysical properties of the seabed and sub-seabed, as unexpected objects can slow down or halt projects. This book presents the state-of-the-art in acoustic exploration of the seabed and sub-seabed, from initial designs in the 1980s to commercial contracting and operation of the Acoustic Corer(tm) in the last decade. The Acoustic Corer(tm) is a high-definition commercial acoustic sub-bottom imaging system, producing an "acoustic core" within which sub-seabed sedimentary characteristics and discrete buried objects larger than 0. 5 m can be identified and mapped. It makes use of the innovative JYG-cross design, inspired by seismic reflection and uses Synthetic Aperture Sonar (SAS) multi-angle scattering in and within the seabed to deliver unprecedented imagery. This book was written by the inventor of these concepts, a known specialist in seabed acoustics, with help from an experienced academic and author. It is intended first and foremost as a "how-to" guide for offshore industries looking at techniques to make the installation of different types of structures safe and efficient.

Acoustic Analysis and Design of Short Elliptical End-Chamber Mufflers
by Akhilesh MimaniThis book presents a three-dimensional analysis of acoustic wave propagation in an elliptical waveguide, and applies the equations and concepts to design axially short elliptical end-chamber muffler configurations which are an important component of a complex multi-pass muffler used in a modern-day automotive exhaust system. A general solution of the Helmholtz equation in elliptical cylindrical co-ordinates is presented in terms of the Mathieu and modified Mathieu modal functions. This is followed by the tabulation and analysis, for the first time, of the non-dimensional resonance frequencies of the transverse modes of a rigid-wall elliptical waveguide for a complete range of aspect ratio. The modal shape patterns of the first few circumferential, radial and cross-modes are examined with particular attention to the pressure nodal ellipses and hyperbolae. An analytical formulation is then outlined for characterizing a single-inlet and single-outlet elliptical muffler with the inlet located on the end face and the outlet located either on the end face or side-surface. The ensuing chapter is devoted toward analyzing the Transmission Loss (TL) performance of different short end-chamber mufflers, namely (a) the straight-flow configuration having ports located on the opposite face, (b) the flow-reversal configuration with ports located on the same end face and (c) configuration with inlet port on the end face and outlet on the side surface. Design guidelines are formulated in terms of the optimal location of inlet and outlet ports which suppresses the deteriorating influence of certain higher-order modes, thereby delivering a broadband TL performance. Directions for future work are discussed toward the end. In summary, this book is a one-stop solution for a practicing automotive engineer designing mufflers, for an applied mathematician studying wave propagation in elliptical geometries, and also as a niche area within noise control engineering.

Acid Mine Drainage in South Africa: Development Actors, Policy Impacts, and Broader Implications (SpringerBriefs in Environmental Science)
by Suvania NaidooThis SpringerBrief focuses on Acid Mine Drainage (AMD) in the three basins in the Witwatersrand, South Africa. It provides a background to AMD and its impactsfrom a social science perspective. The South African government and non-governmental organizations' response to AMD is assessed, as well the socio-economic and developmental effects of AMD. This volume, which is based on the author's Master's dissertation at UNISA, involves interviews with a range of experts in the field from government departments, environmental organisations (activists), the private sector (mining), tourism sector and the agricultural sector. The book discusses existing policy documents on AMD and provides recommendations in response to the many socio-economic impacts which have not been fully addressed. A literature review on the global context of AMD is provided. South Africa's water systems are already severely harmed by climate change, different forms of pollution, and poorly managed sanitation systems. For these reasons, the country is becoming increasingly water-stressed and therefore, water will continue to become much scarcer in the future. As a result of AMD's continued impact on South Africa's water systems, as a technical or scientific matter as well as the policy implications for the mining sector, water security and socio-economic sustainability has become a highly contested issue.

Achieving the Sustainable Development Goals: Global Governance Challenges (Routledge Studies in Sustainable Development)
by Simon Dalby Susan Horton Rianne Mahon Diana ThomazThis book draws on the expertise of faculty and colleagues at the Balsillie School of International Affairs to both locate the Sustainable Development Goals (SDGs) as a contribution to the development of global government and to examine the political-institutional and financial challenges posed by the SDGs. The contributors are experts in global governance issues in a broad variety of fields ranging from health, food systems, social policy, migration and climate change. An introductory chapter sets out the broad context of the governance challenges involved, and how individual chapters contribute to the analysis. The book begins by focusing on individual SDGs, examining briefly the background to the particular goal and evaluating the opportunities and challenges (particularly governance challenges) in achieving the goal, as well as discussing how this goal relates to other SDGs. The book goes on to address the broader issues of achieving the set of goals overall, examining the novel financing mechanisms required for an enterprise of this nature, the trade-offs involved (particularly between the urgent climate agenda and the social/economic goals), the institutional arrangements designed to enable the achievement of the goals and offering a critical perspective on the enterprise as a whole. Achieving the Sustainable Development Goals makes a distinctive contribution by covering a broad range of individual goals with contributions from experts on governance in the global climate, social and economic areas as well as providing assessments of the overall project – its financial feasibility, institutional requisites, and its failures to tackle certain problems at the core. This book will be of great interest to scholars and students of international affairs, development studies and sustainable development, as well as those engaged in policymaking nationally, internationally and those working in NGOs.

Achieving the Paris Climate Agreement Goals: Part 2: Science-based Target Setting for the Finance industry — Net-Zero Sectoral 1.5˚C Pathways for Real Economy Sectors
by Sven TeskeThis open access book is designed as a continuation of the editor’s 2019 book Achieving the Paris Climate Agreement Goals. This volume provides an in-depth analysis of industry sectors globally, and its purpose is to present emission reduction targets in 5-year steps (2025 to 2050) for the main twelve finance sectors per the Global Industry Classification System. This scientific analysis aims to support the United Nations Principles for Responsible Investment initiative to give sustainability guidance for the global finance industry. The industry sector pathways presented here are based on the latest global and regional 100% renewable energy and non-energy greenhouse gas Representative Concentration Pathways in order to keep climate change significantly under +1.5 C and thereby achieve the Paris Climate Agreement goals. The heart of this book is three chapters presenting the results of industry scenario modelling. These chapters cover twelve industry and service sectors as well as transportation and buildings. The specific energy demand and specific emissions are presented based on the emission accounting concept of “Scope 1, Scope 2 and Scope 3” emission pathways. This methodology has been developed to measure the climate and sustainability index for companies, and this research project expands the methodology to apply it to entire industry sectors. The results presented here are the first overall industry assessments under Scope 1, 2 and 3 from 2020 through 2050. The base for the energy pathways is the scenarios scenarios published in the previous volume. The nonenergy GHG emission scenarios, broken down to agriculture & forestry and industry, are detailed and include all major greenhouse gases and aerosols. The final section of the book presents the main conclusions of the industry pathway development work and recommendations for the finance industry and policy makers. Additionally, future qualitative future investment requirements in specific technologies and measures are presented.
Achieving Sustainability: Critical Barriers and Future Perspectives
by Karen BlincoeThe book provides an assessment of whether sustainability is realizable in the current societal framework. What are the challenges and the barriers - and what are the levers necessary to meet and overcome them?Through a revision of the essence of sustainability the book provides an opportunity to understand the deeper level of the radical change that sustainability represents, and the resistance that is preventing its realization.To build the argument the sustainable development model is compared with current development theories as well as alternative solutions based on utopian models of the past. The book assesses the results that can be achieved within the current systemic framework, based on case stories. It outlines the limitations to sustainability, pointing out and defining the multiple, cross-sectoral and systemic barriers that hinder the transition.Finally, the book offers perspectives on achieving a sustainable future, encompassing the impacts from recent events including the pandemic as well as the multiple mitigation and transition initiatives undertaken globally.Brian Goodwin's QuoteLike the caterpillar that wraps itself up in its silken swaddling bands prior to its metamorphosis into a butterfly, we have wrapped ourselves in a tangled skin from which we can emerge only by going through a similarly dramatic transformation.
