The Algal Bowl

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

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.

Selected for The Globe 100 Books in 2013. The final book in Maude Barlow’s Blue trilogy, Blue Future is a powerful, penetrating, and timely look at the global water crisis — and what we can do to prevent it. The global water crisis has dramatically deepened. The stage is being set for drought on an unprecedented scale, mass starvation, and the migration of millions of refugees leaving parched lands in search of water. The story does not need to end in tragedy. In Blue Future, international bestselling author Maude Barlow offers solutions to the global water crisis based on four simple principles. Principle One: Water Is a Human Right chronicles the long fight to have the human right to water recognized and the powerful players still impeding this progress. Principle Two: Water Is a Common Heritage and Public Trust argues that water must not become a commodity to be bought and sold on the open market. Principle Three: Water Has Rights Too makes the case for the protection of source water and the need to make our human laws compatible with those of nature. Principle Four: Water Will Teach Us How to Live Together urges us to come together around a common threat — the end of water — and find a way to live more lightly on this planet. The final instalment in Barlow’s Blue trilogy, Blue Future includes inspiring stories of struggle and resistance from marginalized communities, as well as examples of government policies that work for people and the planet. A call to action to create a water-secure world, it is, in the end, a book of hope.

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.
