International in scope, this book provides a foundation of diverse ideas and approaches to explain complex problems of trees.
A unique report of the current status and future survival of the world's forests compiled by an international independent commission.
Forest damage, forest decline, forest dieback - not related to biotic agents - is occurring in the Atlantic and Pacific regions. In Europe and Eastern North America this serious problem is considered to be, at least to some part, related to industrial air pollutants and their atmospheric conversion products, such as acid rain or ozone. Forest declines in the Pacific region have been attributed largely to natural causes involving forest dynamics, since air pollution and other negative anthropogenic influences are practically absent. Presented here are typical decline phenomena in the Pacific and Atlantic region, potential causes, effects and mitigation strategies, and the question whether there are any similarities on a functional or structural basis is addressed.
Nearly three years ago, world leaders agreed to the United Nations 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs) – the central framework for guiding development policies throughout the world. This edition of The State of the World’s Forests is aimed at enhancing our understanding of how forests and their sustainable management contribute to achieving several of the SDGs. Time is running out for the world’s forests: we need to work across sectors, bring stakeholders together, and take urgent action. The State of the World’s Forests 2018 identifies actions that can be taken to increase the contributions of forests and trees that are necessary to accelerate progress towards the SDGs. It is now critical that steps be taken to work more effectively with the private sector, and the informal forest sector must be transformed in order to bring broader economic, social and environmental benefits. Seventy years ago, when FAO completed its first assessment of the world’s forest resources, the major concern was whether there would be enough timber to supply global demand; now we recognize the greater global relevance of our forests and trees. For the first time, The State of the World’s Forests 2018 provides an assessment of the contribution of forests and trees to our landscapes and livelihoods. The purpose of this publication is to provide a much wider audience with an understanding of why forests and trees matter for people, the planet and posterity.
The idea for this book arose in 1993, after the Free State of Bavaria through its Bayrisches Staatsministerium rur Landesentwicklung und Umweltfragen (Bavarian Ministry of Regional Development and the Environment) decided to discontinue both the Bavarian project management (PBWU) for forest decline research and the multidisciplinary field research on the Wank Mountain in the Alps near Garmisch. Forest decline through the action of ozone and other photooxidants was a main topic of the supported re search in the Alps and will be a topic of new investigations in the Bavarian Forest. Many interesting results were obtained, but the researchers involved have not had sufficient time to allow reliable conclusions to be drawn. It was therefore decided to ask inter national experts for contributions in order to summarize the best available evidence of a possible link between ozone and forest decline - a topic which has been studied in the USA since the late 1950s and in Europe since the early 1980s. The original idea of Waldsterben as an irreversible large-scale dieback of forests in Germany was soon recognized to be wrong (Forschungsbeirat 1989). However, the new criteria used for the official German and European damage inventories (loss or yel lowing of needles or leaves, tree morphology) indicate that per sistently high percentages of damaged spruce and pine remain, and there is an increasing percentage of damaged beech and oak, with a high proportion of biotic disease (Forschungsbeirat 1989; UN-ECE 1995).
The processes and mechanisms that control the growth of woody plants are of crucial importance for both economic and biological reasons. The comprehensive coverage of Growth Control in Woody Plants includes discussion of the growth controlling factors in both reproductive structures (flowers, fruit, seeds, pollen, etc.) and vegetative organs (stems, branches, leaves, and roots). Other major topics covered include seed germination, seedling growth, physiological and environmental regulation of growth, cultural practices, and biotechnology.This comprehensive treatment of the many factors that control the growth of woody plants can serve both as a valuable text and as a frequently used reference. * Includes comprehensive representation of a broad subject* Provides thorough bibliographic coverage * Well illustrated* Serves as a vital companion to Physiology of Woody Plants, Second Edition
Forest decline became a matter of public and scientific concern in France in 1983 when conifers in the Vosges mountains were found to exhibit unusual crown deterioration. An impassioned controversy on a supposedly large scale forest health problem was then in full swing in Central Europe. A co-ordinated research programme entitled DEFORPA ("Deperissement des For~ts et Pollution AtmospMrique") was launched in 1984. This programme ran from 1984 to 1991 and a number of projects are still in progress. The Programme was sponsored by three French ministries (Enviroument, Agriculture and Forestry, Research and Technologyl), several state agencies, various regional authorities and the Commission of the European Communities (DO xn and DG VI). Initially, emphasis was solely laid on the understanding of forest decline in the mountainous areas - because damage was most obvious there - in relation to natural and man-made factors. Air pollution was given high but not overwhelming priority. Thus, the DEFORPA Programme was not in its essence a nation-wide assessment of air pollution effects, unlike a number of national acidification research programmes in Europe and North America. During. the programme, however, the areas of concern expanded. In particular, research into water acidification in the Vosges mountains was developed in parallel with the DEFORPA Programme, and possible eutrophication of the ground flora in northeastern France became the subject of new research.
Like ecology, environmental science is multi- and interdisciplinary. The three major subdisciplines of environmental science are : Population, Resources, Environment. Of the above three major subdisciplines with environmental science, this book is more concerned with the third - the ecological effects of stressors, with particular reference to those associated with the activities of humans. A chapter deals with the use and abuse of biological resources and the emerging field of ecological economics. Some sections deal with environmental impact assessment; ecological monitoring; and the responsibilities of ecologists in environmental issues, environmental education, and the design of sustainable economic systems.
