Book excerpt: The International Energy Agency Bioenergy Agreement was initiated as the Forestry Energy Agreement in 1978. It was expanded in 1986 to form the Bioenergy Agreement. Since that time the Agreement has thrived with some fifteen countries (Austria, Belgium, Canada, Denmark, Finland, Italy, Japan, Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, United States and the CEC) currently being signatories. The objective of the Agreement is to establish increased programme and project cooperation between the participants in the field of bioenergy. The environmental consequences of intensive forest harvesting have been the subject of intense interest for the Agreement from its initiation. This interest was formulated as a Cooperative Project under the Forestry Energy Agreement in 1984. It developed further under each of the subsequent three-year Tasks of the Bioenergy Agreement (Task III, Activity 3 "Nutritional consequences of intensive forest harvesting on site productivity", Task VI, Activity 6 "Environmental impacts of harvesting" and more recently Task IX, Activity 4 "Environmental impacts of intensive harvesting". The work has been supported by five main countries from within the Bioenergy Agreement: Canada, New Zealand, Sweden, UK, and USA. The continued work has resulted in a significant network of scientists work ing together towards a common objective - that of generating a better under standing of the processes involved in nutrient cycling and the development of management regimes which will maintain or enhance long term site productivity.

Maritimes Region and published by Fredericton, N.B. : Forestry Canada - Maritimes. This book was released on 1988 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensive (whole-tree) harvesting of natural forest stands is widespread in the Maritime provinces. In some cases, the goal of whole-tree harvesting is to increase usable biomass, but often foliage and branch components are discarded at the landing site. This report examines the possible effects of whole-tree harvesting on long-term site productivity, and particularly on soil fertility. The report evaluates published data collected from different parts of the world concerning potential decline in soil fertility resulting from the loss of organic matter and base cations caused by different harvesting methods. Biomass and the amount of base cations that would be removed both by conventional and whole-tree harvesting are calculated. Published data from different stands in New Brunswick and Nova Scotia were used to examine the effect of species and site quality on base cation losses and the potential increase in soil acidification which would result from whole-tree harvesting. The consequences of high base cation losses, especially from the infertile acid soils of the region on long-term interfile acid soils of the region on long-term site productivity are discussed.
Download or read book Forest Biomass written by T. Satoo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 160 pages. 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.
