Available in PDF, EPUB and Kindle. Book excerpt: Lord Rutherford has said that all science is either physics or stamp collecting. On that basis the study of forest biomass must be classified with stamp collecting and other such pleasurable pursuits. Japanese scientists have led the world, not only in collecting basic data, but in their attempts to systematise our knowledge of forest biomass. They have studied factors affecting dry matter production of forest trees in an attempt to approach underlying phYf'ical principles. This edition of Professor Satoo's book has been made possible the help of Dr John F. Hosner and the Virginia Poly technical Institute and State University who invited Dr Satoo to Blacksburg for three months in 1973 at about the time when he was in the final stages of preparing the Japanese version. Since then the explosion of world literature on forest biomass has continued to be fired by increasing shortages of timber supplies in many parts of the world as well as by a need to explore renewable sources of energy. In revising the original text I have attempted to maintain the input of Japanese work - much of which is not widely available outside Japan - and to update both the basic information and, where necessary, the conclusions to keep them in tune with current thinking. Those familiar with the Japanese original will find Chapter 3 largely rewritten on the basis of new work - much of which was initiated while Dr Satoo was in Blacksburg.

Download or read book Growth and Allocation of Woody Biomass in Forest Trees Based on Environmental Conditions written by Luigi Todaro and published by MDPI. This book was released on 2021-04-23 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest ecosystems are important because of the key role in reducing atmospheric greenhouse gas concentrations by storing a large amount of carbon in biomass and soils. The relative amount of above-ground biomass allocated among different tree tissues is a functional indicator of forests’ health reflecting the material flow, the wood quality and the plant survival strategy. The way in which plants steer their photosynthetic product across their compartments is not fixed but likely vary over time, across growth economies and among species and, lastly, is influenced by plant size and climate, Obtaining a qualitative/quantitative understanding of the influence that these factors have in both growth and biomass allocation is of fundamental importance either in understanding plant ecology and evolution and into developing environmental policies and useful forest management practices to cope with future climate change.
Download or read book Causes and Consequences of Forest Growth Trends in Europe written by Hans-Peter Kahle and published by BRILL. This book was released on 2008-05-31 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest growth in Europe has been increasing during the last decades. The possible causes suggested to explain this have been increasing atmospheric carbon dioxide concentration, improved temperature and precipitation climate, increasing nitrogen deposition and better management. In this book complementary approaches are used to discriminate between the importance of each of these factors. Investigations over large geographical areas are used to separate current variability while detailed studies of the growth of individual trees allow historical trends to be evaluated. Four different mechanistic forest ecosystem models supplement the empirical investigations. The major cause of the observed growth increase is attributed to the increased nitrogen availability. In future, direct temperature effects and increasing atmospheric carbon dioxide concentration are likely to become important determinants of forest growth. Anyone interested in the future of production and health of Europe's forests should benefit form this extensive analysis of the current status and projections of forest growth.

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.

Book excerpt: Forest biomass is a relevant source of energy and material for the European bioeconomy. The JRC Biomass Assessment Study recognized the need for an up-to-date, harmonized and spatially-explicit estimate of the biomass stock in Europe to better understand its current and future contribution to a sustainable bioeconomy. In this perspective, the present report provides an overview of existing forest biomass data in Europe, describes the methodologies used to harmonize and compare them, and proposes an improved biomass map consistent with the forest inventory data. An analysis of the existing biomass data showed that European countries employ different forest and biomass definitions and provide estimates that refer to different periods and spatial scales. It is therefore essential to perform steps to harmonize the national biomass data and existing biomass maps to perform any meaningful pan-European assessment. The biomass data provided by the National Forest Inventories (NFIs) were first harmonized among each other in terms of biomass definition thanks to a dedicated effort and collaboration of 26 European NFIs. They were then further harmonized with the biomass maps for forest definition and reference year using forest cover maps and a forest growth model within the JRC Biomass Assessment Study. The national statistics were also harmonized by the NFIs regarding the forest area and biomass available for wood supply, using the same reference definition and common criteria to assess wood availability and related restrictions. This data harmonization effort produced a reference database of forest biomass in Europe, which includes statistics at sub-national scale and field plots, both harmonized for biomass pool and reference year. The reference database was used to assess the uncertainties of publically-available biomass maps at different spatial scales. A dedicated analysis quantified the impact of the harmonization of the reference data on the maps validation, highlighting the essential role of the harmonization procedure to obtain reliable results. The validation exercise indicated that, overall, the biomass maps have relatively low accuracy for Europe, especially at local scale, and suggested the need for an improved product. Thus, the map with the highest accuracy was further improved applying a bias-removal approach, where the reference data were used to quantify and remove the systematic difference of the map with the harmonized statistics. The result is a biomass map of Europe at 1 ha resolution for the year 2010 in line with the reference statistics in terms of forest area and biomass stock. The harmonized biomass map along with the harmonized statistics on biomass stock and biomass available for wood supply support an improved estimation of the current and potential supply of biomass resources from European forests as well as their availability and cost, towards a better assessment and modelling of the role of forest biomass in the European bioeconomy. Lastly, this study provides an overview of the current status and the upcoming developments in the field of satellite, airborne and terrestrial remote sensing of forest biomass. As these new technologies are rapidly maturing and becoming operational, they open the possibility for an integrated monitoring system that allows the detailed, frequent and accurate estimate of the forest resources.

Download or read book The Carbon Balance of Forest Biomes written by Howard Griffith and published by Garland Science. This book was released on 2004-08-15 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Carbon Balance of Forest Biomes provides an informed synthesis on the current status of forests and their future potential for carbon sequestration. This volume is timely, since convincing models which scale from local to regional carbon fluxes are needed to support these international agreements, whilst criticisms have been levelled at existing empirical approaches. One key question is to determine how well eddy-flux measurements at the stand-level represent regional-scale processes. This may be related to specific management practices (age, plantation, fertilisation) or simple bias in choosing representative sites (ease of access, roughness, proximity to physical barriers). The ecology and regeneration state of temperate, tropical and boreal forests under current climatic conditions are discussed, together with partitioning of photosynthetic and respiratory fluxes from soils and vegetation. The volume considers how to integrate contrasting methodologies, and the latest approaches for scaling from stand to the planetary boundary layer.
Download or read book Timber consumption and sustainable forest use written by O'Brien, Meghan and published by kassel university press GmbH. This book was released on 2016-07-08 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global demand for timber is increasing, with prognoses for the EU showing particularly high growth to meet renewable energy targets. However, there are limited options to meet rising timber demands within the EU, and global land competition to meet world food, energy and material needs, as well as to conserve high value nature areas, is increasing. This dissertation addresses the knowledge gap between the pressures of increased land use abroad and the underlying drivers of land use change. It argues that there is a high risk of problem shifting if EU policies to increase timber consumption are not accompanied by a monitoring system that accounts for consumption levels and provides a benchmark for sustainability.

Download or read book Increasing Forest Biomass Supply in Northern Europe Countrywide Estimates and Economic Perspectives written by Göran Bostedt and published by . This book was released on 2015 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woody biomass is the largest source of renewable energy in Europe and the expected increase in demand for wood was the stimulus for writing this paper. We discuss the economic effects of biophysical capacity limits in forest yield from a partial equilibrium perspective. Opportunities to increase the supply of forest biomass in the short- and long-term are discussed, as well as environmental side effects of intensive forest management. Focusing on northern Europe, national estimates of potential annual fellings and the corresponding potential amounts, simulated by the European Forest Information Scenario model (the EFISCEN model) are then resented, as well as reported fellings. For the region as a whole, there seems to be substantial unused biophysical potential, although recent data from some countries indicate underestimated annual felling rates. There is a need to discuss strategies to ensure that demand for wood resources in northern Europe can be accommodated without large price increases. However, using a larger proportion of the biophysical potential in northern Europe than at present will entail trade-offs with environmental and social values, which means that strategies are needed to protect and account for all the benefits of all forms of ecosystem services.
Download or read book Status and Dynamics of Forests in Germany written by Nicole Wellbrock and published by Springer Nature. This book was released on 2019-01-01 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an open access publication. Forest ecosystems in Central Europe are changing as a result of anthropogenic influences and changing climate conditions. As such, a large-scale monitoring programme was undertaken in order to understand the influence of site modification, deposition of air pollutants, and climate. This book presents the scientific findings of this study for Germany, including the major challenges with regard to the future preservation and management of forest ecosystems under environmental change. In addition, it addresses a number of central questions: what are the main factors affecting forest stands and soil integrity? How, and how rapidly, are forest ecosystems changing? How diverse are the changes across Germany? What will be the main risks in sustainable forest management in the future? And how can policy support the development and maintenance of adaptive and resilient forests that provide essential ecosystem services, today and in the future? Helping readers understand the importance of soils and related ecosystem processes for future sustainable forestry, and sharing essential findings on environmental change and related changes in forest status and dynamics, the book is a valuable resource for researchers and policymakers interested in science-based decisions.
Download or read book Development of European Forests until 2050 written by G.J. Nabuurs and published by BRILL. This book was released on 2021-11-22 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Europe, forest policy discussions are moving towards a European-Union-wide strategy. This will further strengthen the relations between the European countries in the field of forests and forest management. European-wide forest planning and decision-making require that policy-makers have insight in the long-term development of European forests under alternative regimes. The European Forest Information Scenario Model (EFISCEN) was used to make projections of the development of the European forests under four different scenarios. This book addresses the consequences of each scenario for wood production, biodiversity, and the environmental functions of the forest. The results provide policy-makers with a challenge of whether to intervene in the ongoing trend of build-up of growing stock and whether to choose between enhancing biodiversity, increasing the use of domestically produced wood products, or to combine them.
