Download or read book Growth Trends in European Forests written by Heinrich Spiecker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Forest Institute (EFI) has five Research and Development priority ar eas: forest sustainability, forestry and possible climate change, structural changes in markets for forest products and services, policy analysis, and forest sector informa tion services and research methodology. In the area of forest sustainability our most important activity has been the project "Growth trends of European forests", the re sults of which are presented in this book. The project was started in August 1993 under the leadership of Prof. Dr. Heinrich Spiecker from the University of Freiburg, Germany, and it is one of the first EFI's research projects after its establishment in 1993. The main purpose of the project was to analyse whether site productivity has changed in European forests during the last decades. While several forest growth studies have been published at local, re gional and national levels, this project has aimed at stimulating a joint effort in iden tifying and quantifying possible growth trends and their spatial and temporal extent at the European level. Debate on forest decline and possible climate change, as well as considerations re lated to the long term supply of wood underline the importance of this project, both from environmental and industrial points of view. Knowledge on possible changes in growth trends is vital for the sustainable management of forest ecosystems.

Download or read book Forest Health written by John L. Innes and published by Oxford University Press, USA. This book was released on 1993 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the current state of knowledge about forest declines, particularly as they relate to air pollution. Many declines are shown to be unrelated to air pollution and, in other cases, the links between air pollution and the condition of the trees is extremely tenuous. Factors such as nutrient depletion due to past management practices and drought are shown to have had a major influence on the health of trees. In many cases, the evidence for a decline in tree condition is at best ambiguous, and much of the concern appears to have been generated by political and media interest rather than by a critical evaluation of the available data. A detailed examination of the comprehensive data collected in the British forest health monitoring program over the last five years indicates the complexity of the process involved and illustrates the dangers of taking data from a single year at face value. Many of the indices used to assess trees are of questionable value when compared over time or space, as their subjective nature precludes any reliable comparisons. Studies of annual increment and wood quality indicate that the international market for timber is unlikely to be affected in either the long or the short term.
Download or read book Optimizing Nitrogen Management in Food and Energy Production and Environmental Protection written by J. Galloway and published by CRC Press. This book was released on 2002-01-01 with total page 1042 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of food and energy interfere with the natural nitrogen cycle of the earth. Many of these changes are beneficial, while others are detrimental to societies and the environment. The changing nature of nitrogen in the global environment crosses scientific disciplines, geographical boundaries and political divisions and challenges the creative minds of natural and social scientists, economists, engineers, business leaders and planners. The papers in this book give readers a panoramic view of the changing nature of reactive nitrogen in the global environment, enabling them to make better choices about nitrogen management in food production and consumption, energy production and use, and environmental protection.
