Resumen (en inglés): Declining access to fresh water is one of the twenty-first century's most pressing environmental and human rights challenges, yet the struggle for water is not a new cause. The 8,800-kilometer border dividing Canada and the United States contains more than 20 percent of the world's total freshwater resources, and Border Flows traces the century-long effort by Canada and the United States to manage and care for their ecologically and economically shared rivers and lakes. Ranging across the continent, from the Great Lakes to the Northwest Passage to the Salish Sea, the histories in Border Flows offer critical insights into the historical struggle to care for these vital waters. From multiple perspectives, the book reveals alternative paradigms in water history, law, and policy at scales from the local to the transnational. Students, concerned citizens, and policymakers alike will benefit from the lessons to be found along this critical international border.
Resumen (en inglés): Studies of the radical environmental politics of the 1960s have tended to downplay the extent to which much of that countercultural intellectual and social ferment continued into the 1970s and 1980s. Canadian Countercultures and the Environment adds to our knowledge of this understudied period. This collection contributes a sustained analysis of the beginning of major environmental debates in this era and examines a range of issues related to broad environmental concerns, topics which emerged as key concerns in the context of Cold War military investments and experiments, the oil crisis of the 1970s, debates over gendered roles, and the increasing attention to urban pollution and pesticide use.
No other publication dealing with this period covers the wide range of environmental topics (among others, activism, midwifery, organic farming, recycling, urban cycling, and communal living) or geographic locales, from Yukon to Atlantic Canada. Together, they demonstrate how this period influenced and informed environmental action and issues in ways that have had a long-term impact on Canadian society.

Resumen (en inglés): This book focuses on the interactive effects of environmental stresses with plant and ecosystem functions, especially with respect to changes in the abundance of carbon dioxide. The interaction of stresses with elevated carbon dioxide are presented from the cellular through whole plant ecosystem level. The book carefully considers not only the responses of the above-ground portion of the plant, but also emphasizes the critical role of below-ground (rhizosphere) components (e.g., roots, microbes, soil) in determining the nature and magnitude of these interactions.
* Will rising CO2 alter the importance of environmental stress in natural and agricultural ecosystems? * Will environmental stress on plants reduce their capacity to remove CO2 from the atmosphere? * Are some stresses more important than others as we concern ourselves with global change? * Can we develop predictive models useful for scientists and policy-makers? * Where should future research efforts be focused?
Resumen (en inglés): The importance of carbon dioxide extends from cellular to global levels of organization and potential ecological deterioration may be the result of increased CO2 in our atmosphere. Recently, the research emphasis shifted from studies of photosynthesis pathways and plant growth to ground-breaking studies of carbon dioxide balances in ecosystems, regions, and even the entire globe. Carbon Dioxide and Terrestrial Ecosystems addresses these new areas of research. Economically important woody ecosystems are emphasized because they have substantial influence on global carbon dioxide balances. Herbaceous ecosystems (e.g., grasslands, prairies, wetlands) and crop ecosystems are also covered. The interactions among organisms, communities, and ecosystems are modeled, and the book closes with an important synthesis of this growing nexus of research. Carbon Dioxide and Terrestrial Ecosystems is a compilation of detailed scientific studies that reveal how ecosystems generally, and particular plants specifically, respond to changed levels of carbon dioxide.
Key Features * Contributions from an international team of experts * Empirical examination of the actual effects of carbon dioxide * Variety of terrestrial habitats investigated * Specific plants and whole ecosystems offered as studies
Resumen (en inglés): In past decades and in association with a continuing global industrial development, the global atmospheric concentration of carbon dioxide has been rising. Among the many predictions made concerning this disturbing trend is global warming sufficient to melt polar ice-caps thereby dramatically altering existing shorelines. This book will help fill an obvious gap in the carbon dioxide debate by substituting date for speculation.
* * Includes contributions from leading authorities around the world * Serves as a companion to Carbon Dioxide and Terrestrial Ecosystems * The first book of its kind to explore evolutionary responses of both populations and communities to elevated carbon dioxide
