The greatest threat to water quality worldwide is nutrient pollution. Cultural eutrophication by nutrients in sewage, fertilizers, and detergents is feeding massive algal blooms, choking out aquatic life and outpacing heavy metals, oil spills, and other toxins in the devastation wrought upon the world's fresh waters. Renowned water scientists, David W. Schindler and John R. Vallentyne, share their combined 80 years of experience with the eutrophication problem to explain its history and science, and offer real-world solutions for mitigating this catastrophe in the making. For those who have lost sight of Vallentyne's 1974 first edition, Schindler's fully revised and expanded edition is an unambiguous road map for change.

This book gives information about lakes and explains how they are affected by nutrients derived from human activities.

Water is a human right: “A rousing case for what will be one of the key environmental challenges of the twenty-first century.” —Booklist The United Nations has recognized access to water as a basic human right—but there is still much work to be done to stem this growing environmental crisis. In this book, water activist Maude Barlow draws on her extensive experience to lay out a set of key principles that show the way forward to what she calls a “water-secure and water-just world.” Not only does she reveal the powerful players even now impeding the recognition of the human right to water, she argues that water must not become a commodity to be bought and sold on the open market. Focusing on solutions, she includes stories of struggle and resistance from marginalized communities, as well as government policies that work for both people and the planet. At a time when climate change has moved to the top of the national agenda and the stage is being set for unprecedented drought, mass starvation, and the migration of millions of refugees in search of water, Blue Future is an urgent call to preserve our most valuable resource for generations to come. “In a book as clear as a pristine mountain stream, Maude Barlow lays out a practical and inspiring vision for how we can defend water—the source of all life—from the forces of death.” —Naomi Klein, author of The Shock Doctrine

I believe that it is up to people like us to find the language, create the images and imagine the solutions that will allow us to break out of the vicious circle that threatens public health by threatening our landscapes and water sources . . . Together we can work toward this end. And, we can do it with humour. We can do it with style. And we can do it with grace. Try as we might, parts of North America may not escape the impacts of the global water crisis. The same kinds of water supply and quality issues that have appeared around our crowded planet are already beginning to present themselves here. Unfortunately, this is occurring at a time when, as a direct result of declining global food production, the world is beginning to rely more heavily than ever on agricultural communities in North America to help meet increasingly unattainable food-production goals. Instead of waiting for a water crisis of our own, North Americans may well wish to put the lessons learned elsewhere in the world into active practice. By using the example of others to put our own water-management house in order, North America can possibly avoid the same kinds of problems other countries are facing with respect to the protection of water resources. At the same time, we can employ enlightened attitudes toward the management of water resources to advance many of our own ecological and economic sustainability goals. Passionately conceived, clearly written and citing concrete examples from all over the world, Restoring the Flow is an approachable yet authoritative source, one of the many implements concerned citizens, government officials, businesspeople and policymakers can use and reuse in understanding and addressing this ever-growing global crisis.

This book critically discusses different aspects of algal production systems and several of the drawbacks related to microalgal biomass production, namely, low biomass yield, and energy-consuming harvesting, dewatering, drying and extraction processes. These provide a background to the state-of-the-art technologies for algal cultivation, CO2 sequestration, and large-scale application of these systems. In order to tap the commercial potential of algae, a biorefinery concept has been proposed that could help to extract maximum benefits from algal biomass. This refinery concept promotes the harvesting of multiple products from the feedstock so as to make the process economically attractive. For the last few decades, algal biomass has been explored for use in various products such as fuel, agricultural crops, pigments and pharmaceuticals, as well as in bioremediation. To meet the huge demand, there has been a focus on large-scale production of algal biomass in closed or open photobioreactors. Different nutritional conditions for algal growth have been explored, such as photoautotrophic, heterotrophic, mixotrophic and oleaginous. This book is aimed at a wide audience, including undergraduates, postgraduates, academics, energy researchers, scientists in industry, energy specialists, policy makers and others who wish to understand algal biorefineries and also keep abreast of the latest developments.

Limnology is the study of the structural and functional interrelationships of organisms of inland waters as they are affected by their dynamic physical, chemical, and biotic environments. Limnology: Lake and River Ecosystems, Third Edition, is a new edition of this established classic text. The coverage remains rigorous and uncompromising and has been thoroughly reviewed and updated with evolving recent research results and theoretical understanding. In addition, the author has expanded coverage of lakes to reservoir and river ecosystems in comparative functional analyses.

Sustainable Industrial Processes based on Microalgae addresses the current applications and potential uses of microalgae for processing waste and wastewater streams, along with potential applications of the produced biomass. Each chapter explores the different steps of the subject, from the importance of selecting a robust strain that is able to adapt to harsh and changing environmental conditions, to production and harvesting technologies, and end applications of the produce biomass, namely agriculture and feed production. It covers microalgae biology, common microalgal strains used for waste and wastewater treatment, cultivation strategies, novel extraction techniques, safety issues, and current market opportunities and challenges. Moreover, the book explores the potential utilization of the produced biomass focusing on industries that show higher potential such as agriculture and feed production. - Gives insights in sustainable, energy sufficient and economically-viable microalgae-based processes - Applies microalgal biomass to produce high value biopesticides, bio-stimulants and animal feeds/feed ingredients - Discusses current challenges such as the need for large surface areas and provides suggestions to overcome these challenges
