Lost Waters charts the history of waterscape change for a Moorabool River catchment near Ballarat in the central highlands of western Victoria since white settlement. It is a water supply catchment area where water has been gathered and channelled, waterways reconfigured and connections with local community weakened. In bringing a historical rather than scientific perspective to the issues of water allocation and river management, Erica Nathan considers how people experienced the 'settlement' of water. She questions the central volumetric value that water is given in contemporary debates by discovering a lost geography of water in the knowledge and memory of petitions, water races, picnics, frontage disputes, forest settlements, swimming holes, hidden waterfalls and ti-treed springs. ""Lost Waters"" is a history of one rural waterscape, but with implications that extend to our wider understanding of how water resource conflict is framed and how our waterways are managed. It shows that water has been distilled from its past to produce a resource removed from history and landscapes disconnected from community.
'Quietly triumphant.' Donal Ryan 'Ambitious and gentle.' Belinda McKeon 'A terrific book.' Michael Harding In May 2020, John Connell finds himself, like so many others, confined to his local area, the opportunity to freely travel and socialise cut short. His attention turns to the Camlin river - an ever-present source of life for his town's inhabitants and, for John, a site of boyhood adventure, first love, family history and local legend. He decides to canoe its course with his friend, Sunday Times journalist Peter Geoghegan, a two-day trip requiring physical exertion and mental resilience. As the world grows still around them, the river continues to teem with life - a symphony of buzzing mayfly and jumping trout. During their meander downstream, John reflects on his life: his travels, his past relationships and his battle with depression, as well as on Irish folklore, geopolitics and philosophy. The Stream of Everything is both a reverie and a celebration of close observation; a winding, bucolic account of the summer we discovered home.
Floods constitute a persistent and serious problem throughout the United States and many other parts of the world. They are responsible for losses amounting to billions of dollars and scores of deaths annually. Virtually all parts of the nation--coastal, moun tainous and rural--are affected by them. Two aspects of the problem of flooding that have long been topics of scientific inquiry are flood frequency and risk analyses. Many new, even improved, tech niques have recently been developed for performing these analyses. Nevertheless, actual experience points out that the frequency of say a IOO-year flood, in lieu of being encountered on the average once in one hundred years, may be as little as once in 25 years. It is therefore appropriate to pause and ask where we are, where we are going and where we ought to be going with regard to the technology of flood frequency and risk analyses. One way to address these ques tions is to provide a forum where people from all quarters of the world can assemble, discuss and share their experience and expertise pertaining to flood frequency and risk analyses. This is what con stituted the motivation for organizing the International Symposium on Flood Frequency and Risk Analyses held May 14-17, 1986, at Louisiana State Universj. ty, Baton Rouge, Louisiana."
The Mullica Valley estuary and its watershed, formed over the last 10,000 years, are among the cleanest estuaries along the east coast of the United States. This 365,000-acre ecosystem benefits from a combination of protected watershed, low human population density, and general lack of extensive development. In Beneath the Surface, marine scientist Ken Able helps the reader penetrate the surface and gain insights into the kinds of habitats, the animals, and plants that live there. Readers will gain a better understanding of the importance of these shallow waters; how the amount of salt in the water determines where animals and plants are found in estuaries; the day-night, seasonal, and annual variation in their occurrence; and how change is occurring as the result of climate variation. Throughout the book are insightful sidebars telling intimate stories of where various animals came from and where they are going as they travel through the estuary on their way to and from other portions of the East Coast. Beneath the Surface emphasizes the kinds and importance of the animals and plants that live beneath the surface of this unique ecosystem.
FUNDAMENTALS OF WATER SECURITY Understand How to Manage Water Resources to Equitably Meet Both Human and Ecological Needs Burgeoning populations and the ever-higher standards of living for those in emerging countries increase the demand on our water resources. What is not increasing, however, is the supply of water and the total amount of water in earth's biosphere--water that is integral to all standards of living. Fundamentals of Water Security provides a foundation for understanding and managing the quantity-quality-equity nexus of water security in a changing climate. In a broad sense, this volume explores solutions to water security challenges around the world. It is richly illustrated and pedagogically packed with up-to-date information. The text contains chapter learning objectives, foundation sections reviewing quantitative skills, case studies, and vignettes of people who have made important contributions to water security. To further aid comprehension, end-of-chapter problems are included--both qualitative and quantitative, with solutions available to instructors. Finally, extensive references feature books, journal articles, and government and NGO reports. Sample topics discussed include: How the study of water resources has evolved from a focus on physical availability to include social factors and governance How water security affects multiple disciplines across environmental science and engineering, hydrology, geography, water resources, atmospheric science, chemistry, biology, health science, and social and political science fields How to achieve a sufficient quantity and quality of water to equitably meet both immediate and long-term human and ecological needs Analysis of water security in an integrated manner by underscoring the complex interactions between water quantity, water quality, and society Students taking courses on hydrology, water security, and/or water resource management, along with scientists working in fields where water security is a factor will be able to use Fundamentals of Water Security as a comprehensive textbook to understand and achieve water security.
A BBC Radio 4 Book of the Week 'A subject that could not be more important. A compact classic!' Bill McKibben 'I learned something new - and found something amazing - on every page' Anthony Doerr, author of All the Light We Cannot See From Pulitzer Prize winner Annie Proulx - whose novels are infused with her knowledge and deep concern for the earth - comes an urgent and riveting history of wetlands, their ecological role and how the loss of them threatens the planet. Fens, bogs, swamps and marine estuaries are the earth's most desirable and dependable resources, and in four illuminating parts Proulx documents the emergence of their systemic destruction in the pursuit of profit and the consequent release of their stored carbon. Wide-ranging and idiosyncratic, Proulx's explanation of wetlands takes readers to the fens of sixteenth-century England, Canada's Hudson Bay Lowlands, Russia's Great Vasyugan Mire and America's Okefenokee National Wildlife Refuge and introduces the nineteenth-century explorers who launched the ravaging of the Amazon rainforest. Proulx was born in the 1930s, a time, as she says, when 'in the ever-continuing name of progress, Western countries busily raped their own and other countries of minerals, timber, fish and wildlife.' Fen, Bog & Swamp is both a revelatory history and an urgent plea for wetland reclamation from a writer whose passionate devotion to observing and preserving the environment is on glorious display. 'Magnificent, bringing to life hitherto overlooked habitats' Guardian 'Proulx's sparkling book will open your eyes to humanity's reckless trashing of wetlands' Telegraph 'A haunting tribute ... Proulx's poetic description of these places, and peat itself, is a pleasure to read' Financial Times
This book is open access under a CC BY 4.0 license. This volume focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date. Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.

This book focuses on the effects of industrial effluents, specifically those generated from tanneries, on aquatic life i.e. fish. Readers will learn about the impacts of untreated effluents that find its way into potable water bodies, rivers and lakes. A detailed analysis of the morphological and reproductive responses of fish to Chromium VI, a carcinogen and hazardous metal, will be provided. Particular attention is given to the effects of these effluents on the guppy, a fish used for the biological control of malaria. Students and researchers in environmental science, biology, ecology, marine and freshwater sciences will find the book most appealing. Freshwater ecologists working in the field and managers responsible for the protection and monitoring of natural areas will also find this book interesting.
On 4 June 1629, the Batavia, pride of the Dutch East India Company Fleet, was wrecked on her maiden voyage in a seemingly empty expanse of the Indian Ocean. The question āhow did this happen?ā led to 300 years of investigation by those curious to solve the enigma: what are corals and how are coral reefs formed?. Relying heavily on primary source material Part 1 traces the sequential evolution of scientific thought and practice as the author explores the way this evolution is reflected in the search for understanding corals. At each stage, answers lead to fresh questions that challenge investigators to solve the riddle and new branches of science emerge. Then, with the first enigma finally understood, a new enigma arose. Why are Reefs dying? Part 2 traces the range of problems that have emerged in the past 50 years as marine, ecological, reef and climate scientists attempt to put the pieces of the jigsaw together. Is there a new ācanary in the coal mineā warning of the fate of the world as we know it if manās impact on his environment continues unchecked?.
The book integrates our understanding of the factors and processes underlying the evolution of multicellularity by providing several complementary perspectives (both theoretical and experimental) and using examples from various lineages in which multicellularity evolved. Recent years marked an increased interest in understanding how and why these transitions occurred, and data from various fields are providing new insights into the forces driving the several independent transitions to multicellular life as well as into the genetic and molecular basis for the evolution of this phenotype. The ultimate goal of this book is to facilitate the identification of general and unifying principles and mechanisms.
This book applies the āecosystem servicesā framework to coastal environments, showing how it could facilitate an adaptive management strategy. The contributors describe a decision support system (DSS) based on the 3 Ps ā pluralism, pragmatism and precaution ā that leads to a more flexible, ālearn by doingā approach to the stewardship of coastal environments. The book lays out a āBalance Sheets Approachā to formatting, interrogating and presenting data and findings. The opening chapter defines coastal zones, their characteristics and natural resources, and describes their complex and dynamic nature. The chapter shows that large-scale trends and pressures have led to a global loss of 50% of marshes, leading to significant declines in biodiversity and habitat. Part I presents a conceptual framework, describes natural science techniques for coastal and shelf modeling, and describes valuation of ecosystem services. Part II outlines practical ecosystem indicators for coastal and marine ecosystem services, reviews literature on valuation of coastal and marine ecosystem services, explores scenarios, outlines marine and coastal ecosystem services data and offers tools for incorporating data into decision-making. PART III offers case studies including one linking the ecosystem services of Marine Protected Areas to benefits in human wellbeing; and another on valuing blue carbon captured by oceans and coastal ecosystems. Also included are a study of managed realignments and the English coastline and their value estimate transferability; and studies of the impact of jellyfish blooms on recreation in the UK and on fisheries in Italy.
The book , 'An Introduction to Phytoplanktons - Diversity and Ecology' is very useful as it covers wide aspects of phytoplankton study including the general idea about cyanobacteria and algal kingdom. It contains different topics related to very basic idea of phytoplanktons such as, types ,taxonomic description and the key for identification etc. Together with it, very modern aspects of phytoplankton study including different methodologies needed for research students of botany, ecology, limnology and environmental biology are also included. The first chapter is very basic and informative and describes algal and phytoplankton classification, algal pigments, algal bloom and their control, algal toxins, wetlands algae, ecological significance of phytoplanktons etc. A general key for identification of common phytoplankton genera is also included for students who will be able to identify these genera based on the light microscopic characters. In Chapters 2-4, different aspects of phytoplankton research like primary productivity, community pattern analysis and their ecological parameter analysis have been discussed with detailed procedures. Statistical analysis is also discussed in detail. Chapter 5 includes case studies related to review, phytoplankton diversity and dynamics.
This book isĀ the outcome of rigorous and continuous research work doneĀ by the authorĀ over about three decades on the open ecosystem and dynamic environment of the estuarine Sunderbans. The objective of this work is to identify the field and factors changing gradually upon this active delta over the years, decades and centuries. The deltaic Sunderbans yet not mature enough, has been changing in its natural course with time. Further, anthropogenic interferences disturb the environments and accelerate degradation of nature of this fragile ecosystem simultaneously. Roles played by almost all the agents including man and environment and their involvement are identified for the changing environmental scenario of the Sunderbans. The book is befitted for the researchers andĀ students for the post graduate levels. The Sunderbans, a UNESCO World Heritage Site covering parts of Bangladesh and the southern tip of Indian state of West Bengal, is a part of world's largest deltaic plain of fluvio-marine deposit formed by the Ganges and Brahmaputra at the confluence of the Bay of Bengal. It is the largest single block of tidal halophytic mangrove forest in the world, conspicuous for its great size and biodiversity. With an enormous network of channels and creeks, tidal inundation twice daily, Sunderbans mangroves wetland is a dynamic and complex ecosystem, which undergoes continuous processes of erosion and accretion. Natural processes like changes in local hydrology, sediment motion under wind, wave and tidal action, beach dynamics, regional and global processes like sea level rise as well as the impact of human interference in the form of reclamation of forest land, changes in land use patterns, coastal urbanizations etc are the lead factors for the changes in the environmental scenario of Sunderbans.
It is now widely recognized that there is a need for long-term secure and suitable sustainable forms of energy. Renewable energy from the marine environment, in particular renewable energy from tidal currents, wave and wind, can help achieve a sustainable energy future. Our understanding of environmental impacts and suitable mitigation methods associated with extracting renewable energy from the marine environment is improving all the time and it is essential that we be able to distinguish between natural and anthropocentric drivers and impacts. An overview of current understanding of the environmental implications of marine renewable energy technology is provided.
In this essential new volume, Volume 13: Membrane and Desalination Technologies, a panel of expert researchers provide a wealth of information on membrane and desalination technologies. An advanced chemical and environmental engineering textbook as well as a comprehensive reference book, this volume is of high value to advanced graduate and undergraduate students, researchers, scientists, and designers of water and wastewater treatment systems. This is an essential part of the Handbook of Environmental Engineering series, an incredible collection of methodologies that study the effects of pollution and waste in their three basic forms: gas, solid, and liquid. Chapters adopt the series format, employing methods of practical design and calculation illustrated by numerical examples, including pertinent cost data whenever possible, and exploring in great detail the fundamental principles of the field. Volume 13: Membrane and Desalination Technologies is an essential guide for researchers, highlighting the latest developments in principles of membrane technology, membrane systems planning and design, industrial and municipal waste treatments, desalination requirements, wastewater reclamation, biofiltration, and more.
This book focuses on how marine systems respond to natural and anthropogenic perturbations (ENSO, overfishing, pollution, tourism, invasive species, climate-change). Authors explain in their chapters how this information can guide management and conservation actions to help orient and better manage, restore and sustain the ecosystems services and goods that are derived from the ocean, while considering the complex issues that affect the delicate nature of the Islands. This book will contribute to a new understanding of the Galapagos Islands and marine ecosystems.
The tropical estuarine systems of Mexico and Central America are an important part of the region“s coastlines; for example Mexico alone possesses more than 770 thousand hectares of mangroves, as well as the largest estuarine mangrove complex on the American Pacific (Marismas Nacionales), yet is one of the poorest studied areas in the world. This is the first book that deals extensively with fisheries management issues in this region from physical-chemistry, ecological and socioeconomic views, providing an understanding on the function and the effects of human activities on these areas, with works undertaken by local scientist.
A large number of boreal lakes are ice-covered in winter. However, research and literature of these lakes concerns by far only the open water season. In particular, no textbook on physics of ice-covered lakes exists, and now it would be a proper time to prepare such. Winter limnology has become an increasing active field of research recently. A series of winter limnology symposia was started in 2008 in Finland with nearly 100 participants. The second symposium was held in Berlin in 2010 and the third one is coming in 2012 in Norway. Winter limnologists need strongly a textbook on lake ice physics since the ice acts as their boundary condition.
The U.S. Ocean Commission Report identified the need for regional ecosystem assessments to support coastal and ocean management. These assessments must provide greater understanding of physical and biological dynamics than assessments at global and national scales can provide but transcend state and local interests. This need and timeliness is apparent for Long Island Sound, where a multi-state regional restoration program is underway for America's most urbanized estuary. Synthesis of the Long Island Sound ecosystem is needed to integrate knowledge across disciplines and provide insight into understanding and managing pressing issues, such as non-point sources of pollution, coastal development, global climatic change, and invasive species. Currently, there is a need for a comprehensive volume that summarizes the ecological and environmental dynamics and status of Long Island Sound and its myriad ecosystems. It has been 30 years since a comprehensive summary of Long Island Sound was prepared and 50 years since the pioneering work of Gordon Riley. Major advances in estuarine science are providing new insights into these systems, and yet, the condition of many estuaries is in decline in the face of continuing coastal development. There is an opportunity to lay a foundation for integrative coastal observing systems that truly provide the foundation for improved decision-making. This book will provide a key reference of our scientific understanding for work performed over the past three decades and guide future research and monitoring in a dynamic urbanized estuary.
This work is designed to broaden the scope with which many people regard a river. Rivers are commonly regarded from a very simplistic perspective as conduits for downstream flows of water. In this context, it may be considered acceptable and necessary to engineer the channel to either facilitate such flows (e.g., channelization, levees) or limit flows and store water (e.g., water supply reservoirs, flood control). The book presents the concept of a river as a spatially and temporally complex ecosystem that is likely to be disrupted in unexpected and damaging ways by direct river engineering and by human activities throughout a drainage basin. Viewing a river as a complex ecosystem with nonlinear responses to human activities will help to promote a more nuanced and effective approach to managing river ecosystems and to sustaining the water resources that derive from rivers. In this context, water resources refers to ecosystem services including water supply, water quality, flood control, erosion control, and riverine biota (e.g., freshwater fisheries). Chapters in this book draw extensively on existing literature but integrate this literature from a fresh perspective. General principles are expanded upon and illustrated with photographs, line drawings, tables, and brief, site-specific case studies from rivers around the world. |
