Book Description
Parks Canada has adopted an ecological integrity monitoring framework to guide its biennial assessment of the parks system. This paper focusses on the search for indicators of geological, geomorphological, and soil features, processes, & stresses for that framework. The paper describes indicators developed by the International Union of Geological Sciences, the Canadian Environmental Monitoring & Assessment Network, and the author that have been combined into one list, and assesses each indicator for three criteria: management relevance, linkage with other indicators, and practicality for monitoring. A short list of selected indicators is proposed for further consideration for national park system monitoring. The author also selects indicators that seem best matched to the local environment in five national parks in order to show the variation in indicators among local situations.

Book Description
High mountains can be considered as particularly appropriate environments to detect effects ofclimate change on natural biocoenoses in a global scale for the following reasons: Firstly, ecosystems at the l- temperature limits of plant life are generally thought to be especially sensitive to climate change [1][2][3]. An already ongoing upward shift of vascular plants at high summits in the Alps, determined by the Austrian IGBP-research [4][5][6][7][8], is most likely a response to the atmospheric warming since the 19th century. Secondly, high mountains still comprise the most natural ecosystems in many countries, being largely untouched by human settlements and agricultural influences, Therefore, climatic effects on ecosystems can be studied without masking effects from human land use. Thirdly, high mountain ranges are present in virtually every major zonobiome of the earth. The research initiative GLORIA aims to establish an urgently needed global monitoring network, by using high mountain ecosystems as sensitive indicators, as required in the “IGBP-Mountain Workplan” [9]. Moreover, a deeper understanding of assemblagemechanisms andassemblage processes in vegetation patterns as a contribution to ecological theory can be expected. This paper gives a short general overview about GLORIA and a first outline about the concept, method, and some few results of the “Multi Summit-Approach”, one of the basic intentions within the proposed network. It aims to encourage the involvement of high mountain researchers and research co-ordinators in a detailed discussion of the proposed research activities and in a co-operation within the planned global monitoring network.

Book Description
Environmental Fluid Mechanics (EFM) studies the motion of air and water at several different scales, the fate and transport of species carried along by these fluids, and the interactions among those flows and geological, biological, and engineered systems. EFM emerged some decades ago as a response to the need for tools to study problems of flow and transport in rivers, estuaries, lakes, groundwater and the atmosphere; it is a topic of increasing importance for decision makers, engineers, and researchers alike. The second edition of the successful textbook "Fluid Mechanics of Environmental Interfaces" is still aimed at providing a comprehensive overview of fluid mechanical processes occurring at the different interfaces existing in the realm of EFM, such as the air-water interface, the air-land interface, the water-sediment interface, the surface water-groundwater interface, the water-vegetation interface, and the water-biological systems interface. Across any of these interfaces mass, momentum, and heat are exchanged through different fluid mechanical processes over various spatial and temporal scales. In this second edition, the unique feature of this book, considering all the topics from the point of view of the concept of environmental interface, was maintained while the chapters were updated and five new chapters have been added to significantly enlarge the coverage of the subject area. The book starts with a chapter introducing the concept of EFM and its scope, scales, processes and systems. Then, the book is structured in three parts with fifteen chapters. Part one, which is composed of four chapters, covers the processes occurring at the interfaces between the atmosphere and the surface of the land and the seas, including the transport of dust and the dispersion of passive substances within the atmosphere. Part two deals in five chapters with the fluid mechanics at the air-water interface at small scales and sediment-water interface, including the advective diffusion of air bubbles, the hyporheic exchange and the tidal bores. Finally, part three discusses in six chapters the processes at the interfaces between fluids and biotic systems, such as transport processes in the soil-vegetation-lower atmosphere system, turbulence and wind above and within the forest canopy, flow and mass transport in vegetated open channels, transport processes to and from benthic plants and animals and coupling between interacting environmental interfaces. Each chapter has an educational part, which is structured in four sections: a synopsis of the chapter, a list of keywords that the reader should have encountered in the chapter, a list of questions and a list of unsolved problems related to the topics covered by the chapter. The book will be of interest to graduate students and researchers in environmental sciences, civil engineering and environmental engineering, (geo)physics, atmospheric science, meteorology, limnology, oceanography, and applied mathematics.

Book Description
The context in which environmental policy decision-making occurs has changed, resulting from widening environmental problems, increased demands from groups and citizens, continuing pressure on the continent's resources and normative shifts. The complexity of current issues is related to an even broader contextual shift: the globalization of environmental issues exacerbated by trade liberalization, especially on a regional level and the potential contradictions between trade and the environmental international agenda that this implies. This volume studies the new dimensions of resource conflict between Canada and the United States, accounting for the emergence of new bilateral environmental issues and detailing how trade liberalization has fostered both disputes and policy convergence. It also examines the recent shifts in America towards a unilateral foreign policy and how this affects active Canadian diplomacy Ideal as a resource tool for students and academics, this book will be a key resource in the areas of global governance, US-Canadian foreign policy and environmental policy.

Book Description
In Taking the Air, Paul Kopas takes a comprehensive approach to the policy aspects of the management of parks and protected areas. He scrutinizes the policy-making process for national parks since the mid-1950s and interrogates the rationale and policies that have governed their administration. He argues that national parks and park policy reflect not only environmental concerns but also the political and social attitudes of bureaucrats, citizens, interest groups, Aboriginal peoples, and legal authorities. He explores how the goals of each group have been shaped by the historical context of park policy, influencing the shape and weight of their contributions.

Book Description
Recent critiques of air quality management approaches currently employed in developed and many developing countries have suggested that efficiencies could be achieved if air quality management practices shifted from pollutant-by-pollutant approaches to a comprehensive multipollutant approach in which emission reduction decisions are based on relative risk and evaluated on their effectiveness in meeting environmental and health goals. This book assesses our technical readiness to undertake such an approach, and it outlines the technical developments that will be needed to achieve a risk-based approach air quality management that includes means for measuring the effectiveness of management decisions.
