Acid Mine Drainage in South Africa: Development Actors, Policy Impacts, and Broader Implications (SpringerBriefs in Environmental Science)

by Suvania Naidoo

This 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.

Acknowledging Indigenous Knowledge: Voices of Tropical Forest People (Urbanization, Industrialization, and the Environment)

by Purabi Bose

This book explores how the landscapes in indigenous territories are rapidly changing due to increased global industrial demand. This deforestation and urbanization have isolated the indigenous people from practicing ‘traditional ways of life.’ Portrayed in this book is the indigenous people’s perspective of their indigenous knowledge (IK) about the environment and why losing IK is a threat to humans, wildlife, and nature. Insight is shared into why acknowledging IK as a science can help solve climate change, food and nutrition insecurity, and increasing new types of pandemics through evidence‑based stories from indigenous people. Features:• Bridges the fractured space between science and nature.• Documents the perspectives of indigenous peoples about their ancestral knowledge.• Provides ethnographic qualitative comparative case studies of forest‑dwelling indigenous peoples over a 19‑year period.• Covers largely remote indigenous territories of ten tropical countries in the Global South.• Provides evidence‑based stories examining indigenous knowledge’s role in the tropics in preserving diverse landscapes and providing nature‑based solutions.

Acoustic Analysis and Design of Short Elliptical End-Chamber Mufflers

by Akhilesh Mimani

This 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.

Acoustic Investigation of Complex Seabeds (SpringerBriefs in Oceanography)

by Jacques Yves Guigné Philippe Blondel

Offshore 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.

by Noé Jiménez Olga Umnova Jean-Philippe Groby

This 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.

Across the Great Divide: Explorations In Collaborative Conservation And The American West

by Daniel Kemmis Sarah F. Bates Philip Brick Donald Snow

Amid 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.

by Ziheng Sun

This volume teaches readers how to sort through the vast mountain of climate and environmental science data to extract actionable insights. With the advancements in sensing technology, we now observe petabytes of data related to climate and the environment. While the volume of data is impressive, collecting big data for the sake of data alone proves to be of limited utility. Instead, our quest is for actionable data that can drive tangible actions and meaningful impact.Yet, unearthing actionable insights from the accumulated big data and delivering them to global stakeholders remains a burgeoning field. Although traditional data mining struggles to keep pace with data accumulation, scientific evolution has spurred the emergence of new technologies like numeric modeling and machine learning. These cutting-edge tools are now tackling grand challenges in climate and the environment, from forecasting extreme climate events and enhancing environmental productivity to monitoring greenhouse gas emissions, fostering smart environmental solutions, and understanding aerosols. Additionally, they model environmental-human interactions, inform policy, and steer markets towards a healthier and more environment-friendly direction.While there's no universal solution to address all these formidable tasks, this book takes us on a guided journey through three sections, enriched with chapters from domain scientists. Part I defines actionable science and explores what truly renders data actionable. Part II showcases compelling case studies and practical use scenarios, illustrating these principles in action. Finally, Part III provides an insightful glimpse into the future of actionable science, focusing on the pressing climate and environmental issues we must confront.Embark on this illuminating voyage with us, where big data meets practical research, and discover how our collective efforts move us closer to a sustainable and thriving future. This book is an invitation to unlock the mysteries of our environment, transforming data into decisive action for generations to come.
