The book seeks to comprehend how indigenous knowledge systems of local communities can be effectively used in disaster management of various types. A prime example is the 2015 Sendai Framework for Disaster Risk Reduction, promoting indigenous environmental management knowledge and practices. Traditional knowledge of indigenous peoples includes information and insight that supplement conventional science and environmental observations, a comprehensive understanding of the environment, natural resources, culture, and human interactions with them which is not documented before. A great deal of this knowledge have been lost in translation. In this book, the authors attempt to keep a record of each and every traditional knowledge study of the indigenous communities in managing the disasters. The use of indigenous knowledge systems in disaster understanding and management is the primary focus of the chapters.   This book is organized into four major sections. The first part gives an overview and help in conceptualizing the different concepts of hazard and disaster perception and how response and adaptation are connected with it. This part also discusses the concept of the connection between hazard and sustainable development and how the understanding of risk reduction and resilience can happen with the help of indigenous knowledge, insights, and strategies. The second part of the book introduces the different approaches to disaster and risk management. It establishes how vulnerability influences the risk associated with a hazard and the responses can be both positive and negative in disaster management. The approaches of the indigenous communities in managing a disaster, their resilience, capacity building, and community-based preparedness will be the area of prime focus in this chapter. Part 3 of this book describes the concept of sustainability through indigenous knowledge and practice. The sole highlight of this chapter is the indigenous knowledge efficacies in disaster identification, risk reduction, climate risk management, and climate action. The last section of the book explores how to meet the gaps between local knowledge and policy formulation. It highlights how traditional knowledge of the indigenous communities can prove to be beneficial in developing a holistic regional-based policy framework which will be easily accepted by the target stakeholders since they will be more acquainted with the local strategies and methods. This section ends with an assessment and discussion of the gaps and future scopes in disaster risk reduction through integrating local knowledge and modern technologies.

The paradigm and models of traditional soil science lack the ability to adequately address issues of soil dynamics, environmental integration, and change. Unexplainable research results obtained from traditional soil studies applied to non-traditional soil phenomena in physical geography, archaeology and ecology speak to the current need for soil science to move beyond description and classification and into a dynamic process-oriented soil science capable of providing explanations. Soils do not behave as static inert geologic detritus affected by climate, organisms, relief, and parent material through time, but instead soils behave as self-organizing systems dynamically interrelating with their environment. Recognition of this dynamic behaviour required a re-examination of how scientists in general think and in how modern soil science specifically evolved its basic paradigms and models. This book examines the dynamics of soil organic carbon and demonstrates the self-organizing nature of soil through time as soil responds to a wide range of environmental and human perturbations.

Examining the science of stream restoration, Rebecca Lave argues that the neoliberal emphasis on the privatization and commercialization of knowledge has fundamentally changed the way that science is funded, organized, and viewed in the United States. Stream restoration science and practice is in a startling state. The most widely respected expert in the field, Dave Rosgen, is a private consultant with relatively little formal scientific training. Since the mid-1990s, many academic and federal agency - based scientists have denounced Rosgen as a charlatan and a hack. Despite this, Rosgen's Natural Channel Design approach, classification system, and short-course series are not only accepted but are viewed as more legitimate than academically produced knowledge and training. Rosgen's methods are now promoted by federal agencies including the Environmental Protection Agency, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Natural Resources Conservation Service, as well as by resource agencies in dozens of states. Drawing on the work of Pierre Bourdieu, Lave demonstrates that the primary cause of Rosgen's success is neither the method nor the man but is instead the assignment of a new legitimacy to scientific claims developed outside the academy, concurrent with academic scientists' decreasing ability to defend their turf. What is at stake in the Rosgen wars, argues Lave, is not just the ecological health of our rivers and streams but the very future of environmental science.

In The Big Muddy, the first long-term environmental history of the Mississippi, Christopher Morris offers a brilliant tour across five centuries as he illuminates the interaction between people and the landscape, from early hunter-gatherer bands to present-day industrial and post-industrial society.
Morris shows that when Hernando de Soto arrived at the lower Mississippi Valley, he found an incredibly vast wetland, forty thousand square miles of some of the richest, wettest land in North America, deposited there by the big muddy river that ran through it. But since then much has changed, for the river and for the surrounding valley. Indeed, by the 1890s, the valley was rapidly drying. Morris shows how centuries of increasingly intensified human meddling--including deforestation, swamp drainage, and levee construction--led to drought, disease, and severe flooding. He outlines the damage done by the introduction of foreign species, such as the Argentine nutria, which escaped into the wild and are now busy eating up Louisiana's wetlands. And he critiques the most monumental change in the lower Mississippi Valley--the reconstruction of the river itself, largely under the direction of the Army Corps of Engineers. Valley residents have been paying the price for these human interventions, most visibly with the disaster that followed Hurricane Katrina. Morris also describes how valley residents have been struggling to reinvigorate the valley environment in recent years--such as with the burgeoning catfish and crawfish industries--so that they may once again live off its natural abundance.
Morris concludes that the problem with Katrina is the problem with the Amazon Rainforest, drought and famine in Africa, and fires and mudslides in California--it is the end result of the ill-considered bending of natural environments to human purposes.

The most pressing problems facing humanity today - over-population, energy shortages, climate change, soil erosion, species extinctions, the risk of epidemic disease, the threat of warfare that could destroy all the hard-won gains of civilization, and even the recent fibrillations of the stock market - are all ecological or have a large ecological component. in this volume philosophers turn their attention to understanding the science of ecology and its huge implications for the human project.
To get the application of ecology to policy or other practical concerns right, humanity needs a clear and disinterested philosophical understanding of ecology which can help identify the practical lessons of science. Conversely, the urgent practical demands humanity faces today cannot help but direct scientific and philosophical investigation toward the basis of those ecological challenges that threaten human survival. This book will help to fuel the timely renaissance of interest in philosophy of ecology that is now occurring in the philosophical profession.

The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 g per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium's origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

'Physical Properties of Rocks - a Workbook' is a symbiosis of a brief description of physical fundamentals of rock properties (based on typical experimental results and relevant theories and models) with a guide for practical use of different theoretical concepts. For this purpose a companion web site contains a selection of model based equations in excel worksheets for practical application and training by the user to work with his own data (or to ''play" in order to demonstrate the effects of various input information and to demonstrate the effects of various input information in petrophysical work.

In two special chapters the problem of relationships between petrophysical parameters based on various model concepts is presented as a foundation for combined interpretation. This part also contains the author's 'structured model'.

The workbook is a result of the more than 40 years experience of the author in teaching at universities and industrial courses.
