Download or read book Effects of Acid Precipitation on Terrestrial Ecosystems written by Thomas C. Hutchinson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at a NATO Advanced Research Institute, sponsored by their Eco-Sciences Panel, on "The effects of acid precipitation on vegetation and soils," held at Toronto, Canada from May 22-26, 1978. The organizing expenses and greater part of the expenses of the speakers and chair~en were provided by N.A.T.O. The scientific programme was planned by T. C. Hutchinson together with an international planning committee of G. Abrahamsen (Norway), G. Likens (U.S.A.), F.E. Last (U.K.), C.O. Tamm (Sweden) and B. Ulrich (W. Germany). Many of the dimensions of the 'acid rain' problem are common to countries of northern Europe and North America. The developing awareness over the past ten years of the international nature of the acid rain phenomenon has lead to studies documenting damaging effects on susceptible freshwater bodies. Large areas of the Canadian Pre-Cambrian Shield, with its extension into the United States, and the granitic areas of southern Norwayand Sweden contain lakes which are in the process of acidification. The biological resources of these affected areas are of considerable national concern. However, while clearly damaging effects of acidification on freshwater systems have been well documented, the impact of acid precipitation on terrestrial systems has not been so well understood.

Download or read book Balancing Act written by J P Hamish Kimmins and published by UBC Press. This book was released on 2011-01-01 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, there has been much debate over the environmental impact of forestry. People are justifiably concerned about what is happening to the local and global forest environments, but they are also confused by the polarized rhetoric that has characterized both sides of the debate. In Balancing Act, Hamish Kimmins calls for a balanced, more objective approach to forestry issues in order to bridge the gap between the most extreme opponents in the debate. He suggests that we need to begin with a common understanding of what forestry is about and how forest ecosystems work. He outlines the scientific and ecological aspects of the major environmental issues facing British Columbia and the world today, arguing that we need to disentangle the scientific from the value-based social aspects of these questions. He also contends that much of the current debate about forests and their management ignores the time dimension of ecosystems, and he calls for a more dynamic view of current environmental issues in forestry -- one that accounts for change. The first few chapters provide an outline of the basic principles of forestry and ecology, and subsequent chapters discuss the major environmental issues facing forestry in the 1990s. These include clearcutting, slashburning, management chemicals, old growth, biological diversity, 'new forestry, ' climate change, acid rain, the comparison between temperate and tropical forestry, and long-term decisions in forestry. Balancing Act is essential reading for those who are searching for an objective, accurate, and readable evaluation of the issues at the heart of the forestry/environment debate. By emphasizing that forests are not static but change over time, Kimmins adds an important, often ignored, dimension to the discussion. Only by understanding all the intricacies of the ecosystems can we learn to manage our forests in a sustainable fashion.

These are illustrated with colour photographs for easy identification. The book is divided into three major colour-coded sections: one for insects and diseases of conifers, one for insects and diseases of hardwoods, and one for other damaging agents.

Download or read book Cumulative Environmental Effects written by National Research Council (U.S.). Committee on Applications of Ecological Theory to Environmental Problems and published by . This book was released on 1986 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cumulative effects of multiple environmental perturbations of natural and social systems were identified as needing study because of a lack of a clear and unambiguous definition of cumulative effects assessment, despite the widespread recognition of its importance. There is increasing concern that neither scientists nor institutions work at the temporal and spatial scales needed for the assessment of cumulative effects. The workshop explored these issues, identified current scientific and management techniques of dealing with cumulative effects, and to recommended research and management priorities for improving the management of cumulative effects.
