      Rust Diseases of Willow and Poplar

      by Edited by Ming H Pei, Alistair R McCracken

      In recent years there has been increased interest in growing willow and poplar trees, as fast-growing species that have several purposes, including use as biofuels for energy production. However, silviculture of these trees has been constrained by diseases such as Melampsora rusts. This book provides a comprehensive review of over two decades of extensive study of the rust diseases affecting willow and poplar. It provides insights into the population biology of Melampsora rusts in Europe, China, India and Chile, the genetics of their resistance, and their interaction with their hosts. The book offers information essential to the development of effective and sustainable disease control measures including the use of willow genotype mixtures and biological control agents.

      Valuing Mediterranean Forests

      Towards Total Economic Value

      by Edited by Maurizio Merlo, Lelia Croitoru

      This book provides a comprehensive analysis of the economic value of Mediterranean forests, including not only the more obvious benefits (e.g. timber), but also the less commonly-measured public goods (e.g. tourism and conservation) that these forests provide. It brings together forest valuations at the national level from eighteen Mediterranean countries, based on extensive local data collection, and thus allows comprehensive analyses within countries as well as comparative analyses across countries. Forest benefits were classified within the Total Economic Value (TEV) framework. The book describes the valuation techniques used and examines ways to overcome the problems encountered. The book explores the research findings in the context of the institutions and policies that affect Mediterranean forests and proposes new policy approaches for improving forest policies and management at the national, regional and local levels. It is also shown how the methodologies used can be applied to other regions.

      Trees, Crops and Soil Fertility: Concepts and Research Methods

      by Edited by Goetz Schroth, Fergus L Sinclair

      Successful agroforestry requires an understanding of the complex relationship between trees, crops and soils. This book provides a review of both economic and biophysical aspects of soil use and research in agroforestry, with an emphasis on nutrient-poor forest and savanna soils. Key topics covered include the economics of soil fertility management, cycling of water, nutrients and organic matter, soil structure, and soil biological processes. The book combines synthetic overviews of research results and a review of methods used in research.From the foreword: “The book is written within a particular context - soil fertility development under agroforestry. At first this may seem very specific and thus limited in appeal and application. But over the last decade or so agroforestry research has been one of the most influential in developing new insights into soil biology and fertility and thus provides a very suitable framework for review of progress. Furthermore the influence of trees on soil is profound and of significance beyond agroforestry systems, so the book is likely to be of interest in the wider spheres of agriculture, forestry and ecological sciences.” Mike Swift, TSBF, Nairobi, Kenya

      Trees on the Farm

      Assessing the Adoption Potential of Agroforestry Practices in Africa

      by Edited by Steven Franzel, Sara J Scherr

      Most published books on agroforestry have focused on biophysical aspects. There has been a lack of scientifically rigorous information about the socioeconomic features of agroforestry, and the adoption of agroforestry practices by farmers.This book fills that gap by assessing the adoption of selected agroforestry practices developed with African farmers, describing methods, and drawing out the implications for research, development, and policy. The volume includes five case studies of research conducted in Kenya and Zambia to evaluate the adoption potential of agroforestry. The cases illustrate methods of farm and village technology design, testing, and analysis that are applicable to a wide range of natural resource management practices.Along with the case studies, the contents also include chapters on: methods for assessing agroforestry adoption potential, promoting new agroforestry technologies: policy lessons from on-farm research, and assessing adoption potential: lessons learned and future directions.

      Measuring Trees and Forests

      by Michael S Philip

      Forest mensuration provides data on aspects of length, mass and time of areas of forest, individual trees or parcels of felled timber. Such quantitative information is vital to sellers, buyers, planners, managers and researchers within forestry. This book is a revision of a successful text originally published in 1983 but written for students in Africa. The new edition is international in scope, and has also been changed and updated to reflect recent advances, particularly with respect to biomass and fodder measurement, sampling with unequal probabilities and growth modelling. The book covers both the theory and practice of forest mensuration and includes a number of worked examples of calculations. It is a basic textbook for students of forestry and will also be of value to practising foresters.

      Ecology and Silviculture of Oaks

      by Paul S Johnson, Stephen R Shifley, Robert Rogers

      The management of oak forests is essential to the ecosystems of many countries, and current trends in managing forests are based on sustaining desired ecosystems, rather than timber and other commodity outputs. By considering oak forests as responsive ecosystems, this updated new edition draws on the authors' extensive experience in order to examine topics essential to understanding the unique characteristics of oaks and oak forests, covering distribution, ecology and population dynamics, and silvicultural practices for multi-resource management such as creating and sustaining oak savannas, and increasing and measuring acorn production. With new information on carbon sequestration, biofuel production, impacts of climate change, and sudden oak death - a serious and newly discovered pathogen - the book will be essential reading for ecologists, silviculturists, environmentalists, wildlife managers and students in these disciplines.

      Planted Forests

      Uses, Impacts and Sustainability

      by James B. Carle, J. B. Ball, Alberto Del Lungo, D. A. Neilson, L. P.B. Holmgren. Edited by Julian Evans.

      Planted forests, although only seven per cent of the world's forest resources, have superseded naturally regenerating forests as the principal source of industrial wood products. Lessening the pressure for wood production, tree planting has released natural forests to be managed for other purposes - carbon sinks, soil and water protection, conservation of biological diversity, recreation and amenity. Representing a complement, but not an alternative, to natural forests, planted forests have become increasingly important for reducing worldwide deforestation, loss of forest ecosystems and forest degradation. Examining the significance of this rapidly emerging world resource, chapters consider the strengths and weaknesses of planted forests, management objectives for their use and aspects of ownership and policy. Data from key production countries are used to evaluate the implications and sustainability of planted forests as a source of forest products as well as social and ecological issues.

      Forests and Landscapes

      Linking Ecology, Sustainability and Aesthetics

      by Edited by Eric Wajnberg, John K Scott, Paul C Quimby

      Forests are an important component in the visual appeal of landscapes. There is an increasing recognition of the importance of this subject among foresters and environmental scientists. Increasingly, forest resource managers must consider both the aesthetic consequences of timber harvesting operations and management plans and public perceptions of the sustainability of forest eco-system management.Written by world class authorities this book is the first to address this subject area. It consists of 17 chapters and is divided into six parts. The interdisciplinary nature of the book brings together not only foresters and ecologists, but also landscape architects, psychologists and philosophers. Contributors are leading research workers in their subjects, from Canada, the USA and UK.

      Grazing Ecology and Forest History

      by Edited by Franciscus W M Vera

      It is a widely held belief that a climax vegetation of closed forest systems covered the lowlands of Central and Western Europe before humans intervened in prehistoric times to develop agriculture. If this intervention had not taken place, it would still be there and so if left, the grassland vegetation and fields we see today would revert to its natural closed forest state, although with a reduced number of wild species. This book challenges this view, using examples from history, pollen analyses and studies on the ecology of tree and shrub species such as oak and hazel. It tests the hypotheses that the climax vegetation is a closed canopy forest against the alternative one in which species composition and succession of vegetation were governed by herbivores and that the Central and Western European lowlands were covered by a park-like landscape consisting of grasslands, scrub, solitary trees and groves bordered by a mantle and fringe vegetation. Comparative information from North America is also included, because the forests there are commonly regarded as being analogous to the primeval vegetation in Europe. This title is a revised, updated and expanded translation of book published in Dutch.

      Air Pollution and the Forests of Developing and Rapidly Industrialising Countries

      by Edited by John L Innes, Abu H Haron

      This book examines the importance of air pollution for the forests of rapidly industrialising countries and regions. Its geographical coverage includes South and Central America, Africa, and Asia, including Siberia, China and Korea. The problems presented by air pollution are placed within the more general context of sustainable development within these regions and the historical legacy that they are attempting to deal with. Attention is drawn to the very serious problems associated with poor air quality in cities such as Mexico City and Chongqing, China. Air pollution in these areas is amongst the worst in the world. Several chapters examine the importance of forest fires as a source of air pollution, with particular reference being made to the Southeast Asian fires in recent years. The available information about the effects of this pollution on the surrounding forests is reviewed, and recommendations are made for a better understanding of the impacts. A final chapter reviews the recent developments in air pollution control policies in the different regions covered by the book.

      Agroforestry for Soil Management

      by Edited by Anthony Young

      Agroforestry refers to land use systems in which trees or shrubs are grown in association with agricultural crops, or pastures and livestock. From its inception, it has contained a strong element of soil management. Well-designed and managed agroforestry systems have the potential to control run-off and erosion, maintain soil organic matter and physical properties, and promote nutrient cycling. By these means, agroforestry can make a major contribution to sustainable land use. The previous edition of this book, entitled Agroforestry for Soil Conservation (1989), was based on indirect evidence from agriculture, forestry and soil science. The present work provides a new synthesis, drawing on over 700 published sources dating largely from the 1990s. These include both results of field trials of agronomy systems, and research into the plant-soil processes which take place within them. Soil conservation in its narrower sense, the control of erosion, is treated alongside other equally important aspects of soil management, such as nutrient cycling. The new edition summarizes the present state of knowledge and indicates needs for research. It is essential reading for all concerned with agroforestry, whether as students, research scientists, or for practical purposes of development. It is also of interest to soil scientists, agronomists and foresters. Anthony Young was for nine years a Principal Scientist with the International Centre for Research in Agroforestry (ICRAF), Nairobi, Kenya. He was previously Professor of Environmental Sciences at the University of East Anglia, Norwich, UK, from which he received the degree of Doctor of Science. He was a joint author of the FAO standard texts on land evaluation and land use planning. Besides these, his other books include Soil Survey and Land Evaluation (1981) and Land Resources: Now and for the Future (1998). He is now Honorary Research Fellow in Environmental Sciences at the University of East Anglia.

      Temperate Agroforestry Systems

      by Edited by Professor Andrew M Gordon

      Agroforestry is a land use system that allows for the concurrent production of trees and agricultural crops from the same piece of land. It has a rich history of development and has been practised in some parts of the world for more than 6,000 years. Much recent research into agroforestry has been carried out in the tropics and within the context of developing nations, where land shortages brought about by the rapid growth in population demand that efficient production systems for both wood and food be developed and enhanced. In temperate zones, the awareness of some of the faults inherent within traditional agricultural systems has led to much increased research and practical activity in the development of sustainable farming systems. Agroforestry can play a leading role in this area, particularly in silvopastoral as well as cropping systems, and in promoting soil conservation. This book explores the development of temperate agroforestry and agroforestry systems, concentrating on those areas within the temperate zones where the greatest advances, adoptions and modifications have taken place: North and South America, China, Australia, New Zealand, the United Kingdom and Continental Europe. The book is the first text to bring together so many examples of temperate agroforestry and is valuable reading for all those working in this area as researchers, practitioners and policy makers. The book is also of importance to students and teachers of agriculture, ecology, environmental studies and forestry in temperate regions.

      Conservation and Management of Tropical Rainforests

      An integrated approach to sustainability

      by Eberhard F Bruenig

      Tropical rainforests fascinate scientists and explorers. The richness and variety of forms, and the diversity of species have been acknowledged for centuries. Measures to protect endangered species within this ecosystem were already thought necessary in the mid-nineteenth century. Since the 1920s commercial greed, political misdemeanour and the relentless increase in the human population have all posed increasing threats to the future of rainforests. Sustainability is now of paramount importance. This book applies the large body of knowledge, experience and tradition available to those who study tropical rainforests. It describes the principles of integrated conservation and management that lead to sustainability. It identifies the unifying phenomena that regulate the processes within the rainforest and that are fundamental to the ecosystem viability. Features of the natural forest and the socio-cultural ecosystems which can be mimicked in the design of self-sustaining forests are also discussed. A holistic approach to the management and conservation of rainforests is developed throughout the book. Many practical examples and field studies from Amazonia and South East Asia, particularly Sarawak, are included. This book is a substantial contribution to the literature, it is a valuable resource for all those concerned with rainforests.
