The influence of the past, and of the future on current-time tradeoffs in the forest arena are particularly relevant given the long-term successions in forest landscapes and the hundred years' rotations in forestry. Historically established path dependencies and conflicts determine our present situation and delimit what is possible to achieve. Similarly, future trends and desires have a large influence on decision making. Nevertheless, decisions about forest governance and management are always made in the present - in the present-time appraisal of the developed situation, future alternatives and in negotiation between different perspectives, interests, and actors. This book explores historic and future outlooks as well as current tradeoffs and methods in forest governance and management. It emphasizes the generality and complexity with empirical data from Sweden and internationally. It first investigates, from a historical perspective, how previous forest policies and discourses have influenced current forest governance and management. Second, it considers methods to explore alternative forest futures and how the results from such investigations may influence the present. Third, it examines current methods of balancing tradeoffs in decision-making among ecosystem services. Based on the findings the authors develop an integrated approach - Reflexive Forestry - to support exchange of knowledge and understandings to enable capacity building and the establishment of common ground. Such societal agreements, or what the authors elaborate as forest social contracts, are sets of relational commitment between involved actors that may generate mutual action and a common directionality to meet contemporary challenges.
The book is a fundamental reference source on reaction wood for wood scientists and technologists, plant biologists, silviculturists, forest ecologists, and anyone involved in the growing of trees and the processing of wood. It brings together our current understanding of all aspects of reaction wood, and is the first book to discuss both compression wood and tension wood. Trees produce reaction wood to maintain the vertical orientation of their stems and the optimum angle of each branch. They achieve this by laying down fibre cell walls in which differences in physical and chemical structure from those of normal fibres are expressed as differential stresses across the stem or branch. This process, while of obvious value for the survival of the tree, causes serious problems for the utilisation of timber. Timber derived from trees containing significant amounts of reaction wood is subject to dimensional instability on drying, causing twisting, bending and splitting. It is also difficult to work as timber, and for the pulp and paper industry the cost of removing the increased amount of lignin in compression wood is substantial. This has both practical and economic consequences for industry. Understanding the factors controlling reaction wood formation and its effect on wood structure is therefore fundamental to our understanding of the adaptation of trees to their environment and to the sustainable use of wood. The topics covered include: -Morphology, anatomy and ultrastructure of reaction wood -Cell-wall polymers in reaction wood and their biosynthesis -Changes in tree proteomes during reaction wood formation -The biomechanical action and biological functions of reaction wood -Physical and mechanical properties of reaction wood from the scale of cell walls to planks -The detection and characterisation of compression wood -Effects of reaction wood on the performance of wood and wood-based products -Commercial implications of reaction wood and the influence of forest management on its formation "
Since the 1992 Earth Summit, there have been increased efforts on an international scale to address global climate change. Reducing the increased levels of CO2 and other "greenhouse gases," which are believed to be contributing to this climatic change, will require major effort on the part of the world's governments. This means that the environmental, economic, social, and political consequences of climate change must be understood, and that strategies to mitigate climate change must also address these issues.
This title aims to provide introductory and concluding surveys of the subject of farms, trees and farmers. Two central parts explore trends in farmer tree-growing and the factors which influence decision-making. Eight case studies cover, among other topics, the need for tree products, market access, the allocation of land and labour, and exposure to risk. In showing why farmers decide to grow or not grow trees, it seeks to increase the reader's knowledge about farming systems and to provide a guide to encouraging farm forestry throughout the world.
As a natural science, silviculture has a large say in how humans interact with the terrestrial world. Although the perspective taken here that the production of wood is narrow, the amount of land area consumed is extensive; the indirect consequences of wood production on natural processes are larger still. Through the amount of land engaged, the flora and fauna affected and the environmental consequences, good or bad; silviculture is a frequent constituent in applied ecology, environmental science, conservation ecology and other broad land-use disciplines. Silvicultural expertize is essential when trees and wood are an economic output; often best promoted when silviculture is allied with hydrology, ecology, soil science, wildlife management, etc. This book touches upon the following important areas of the subject in detail.
This book addresses an important topic of food security in South Asia with specific reference to climate change. Of the 1 billion food insecure people in the world, more than 30% are in South Asia. The problem of food insecurity may be exacerbated by the projected climate change especially because of the water scarcity caused by rapid melting of the glaciers in the Himalayas and increase in variability in monsoonal rains and frequency of extreme events. Furthermore, large populations of Bangladesh and other coastal regions may be displaced by sea level rise. Thus, this volume addresses recommended land use and soil/water/crop/vegetation management practices which would enable land managers to adapt to climate disruption by enhancing soil/ecosystem/social resilience. In addition to biophysical factors, this book also addresses the issues related to human dimensions including social, ethnical and political considerations.
Forestry today, like many other sectors that traditionally rely on material goods, faces significant global drivers of societal change that are less often addressed than the environmental concerns commonly in the spotlight of scientific, political, and news media. There are three major interconnected issues that are challenging forestry at its foundation: urbanization, tertiarization, and globalization. These issues are at the core of this book. The urbanization of society, a process in development from the first steps of industrialization, is particularly significant today with the predominance and quick growth rate of the world's urban population. Ongoing urbanization is creating new perspectives on forestry, inducing changes in its social representation, and changing lifestyles and practices with a tendency toward dematerialization. The process of urbanization is also creating a disconnect and in some ways is leaving behind rurality, the sector of society where forestry has traditionally developed and taken place over centuries. The second issue covered in this book is the tertiarization of the economy. In society today, the sector of services largely dominates the economy and occupies the major part of the world's active population. This ongoing process modifies professional modalities and ways of life and opens new doors to forests through the immaterial goods they provide. It also profoundly changes the framework, rules, processes, means of production, exchanges between economic factors, and the processes of innovation. The third issue is undoubtedly globalization in its economic, political, and social components. Whether it's through bridging distances, crossing borders, accelerating changes, standardizing practices, leveling hierarchical structures, or pushing for interdependence, globalization impacts everyone, everywhere in multiple ways. Forestry is no exception. Forestry in the Midst of Global Changes focuses on these global drivers of change from the perspective of their relationships with how society functions. By analyzing them in depth through multidisciplinary, interdisciplinary, and even transdisciplinary approaches, this book is helping to design the forestry of tomorrow.
This is the first truly modern book solely devoted to seed reproduction of forest trees-from flowering to establishment, with emphasis on the interaction of environment with physiological processes.
First published in 1995, The Forest Certification Handbook has become the landmark book concerning all aspects of forest and wood product certification from policy to business to in-the-field technical issues. Yet since first publication an enormous amount has happened in the field. This new second edition has been entirely rewritten to incorporate the changes over the past decade, and is a complete and up-to-date source of information on all aspects of developing, selecting and operating a forest certification programme that provides both market security and raises standards of forest management.
Examines the management and use of common-property forests, groves and trees on southern Mount Kenya, demonstrating the long-standing relationships between Kenyans and their forest resources - and the connections between anthropology and forestry. This book is published in the IT Studies in Indigenous Knowledge and Development series.
The last decade saw dramatic concern for forest problems. The
future decades will witness an even more dramatic interest.
Certification of forests provides a guarantee to buyers of timber
products that their purchases come from well-managed forests that
will not support unsustainable or inequitable practices. This
produces multiple advantages to those with stakes in the entire
chain of production, not the least of which is justification of
their pricing. The Forest Certification Handbook is the first book
to fully assess the role of certification and provide practical
advice on developing, selecting and operating a program.
The world's forests are disappearing at an alarming rate, and with disastrous consequences. Demand for wood and paper products ranks high amongst the causes of deforestation and forest degradation, and is now the major cause of loss in those forests richest in wildlife. There is a great deal to be done to improve the timber industry before our forests are safely and sustainably managed. Bad Harvest presents an incisive account of the role that the timber trade has played in the loss and degradation of forests around the world. It examines the environmental consequences of the trade on boreal, temporal and tropical regions, and its impacts for local people working and living in the forests. It also looks at the changing nature of the trade, and assesses current national and international initiatives to address the impacts of deforestation. Finally, the authors show how things could be improved in the future, by presenting a new strategy for sustainable forest management. Based on 15 years of extensive research - particularly work carried out by the World Wide Fund for Nature - Bad Harvest is essential reading on the subject; not only for environmentalists, but also for those in the timber trade seeking to improve the management and reputation of their product.
There has been a recent resurgence of interest in wood energy as part of a sustainable range of renewable energy options. This book addresses the current gap in the energy and public policy literature for a reference book that compiles the most-recent wood energy assessments, and evaluates current and potential future wood energy uses and the role for public policy to foster efficient use of the most-widely consumed renewable energy in the world. It brings together a group of expert authors covering topics from forest management, operations and engineering, to socio-economics and energy policy perspectives. It thus covers practical issues such as silviculture, harvesting, processing, comparative cost estimates, public policy tools and market effects. As such the book provides a comprehensive review of the complex dimensions of wood energy as well as practical guidance for professionals, researchers and advanced students. It will also provide invaluable guidance for economic development agencies, practitioners and policy-makers, when evaluating the impacts of wider wood energy adoption as part of a strategy for sustainable energy generation. The main focus is on industrialised production and developed economies, particularly the USA and Europe.
Since the first edition of our book "Tissue Culture in Fores try" in 1982 we have witnessed remarkable advances in cell and tissue culture technologies with woody perennials. In addition to forest biologists in government, industry, and universities, we now have molecular biologists, genetic engineers, and biochemists using cell and tissue cultures of woody species routinely. There fore, the time has come for an update of the earlier edition. In our present effort to cover new developments we have expanded to three volumes: 1. General principles and Biotechnology 2. Specific Principles and Methods: Growth and Development 3. Case Histories: Gymnosperms, Angiosperms and Palms The scientific barriers to progress in tree improvement are not so much lack of foreign gene expression in plants but our current inabili ty to regenerate plants in true-to-type fashion on a mas sive and economic scale. To achieve this in the form of an appro pr iate biotechnology, cell and tissue culture will increasing ly require a better understanding of basic principles in chemistry and physics that determine structural and functional relationships among molecules and macromolecules (proteins, RNA, DNA) within cells and tissues. These principles and their relationship with the culture medium and its physical environment, principles of clonal propagation, and genetic variation and ultrastructure are discussed in volume one."
Today, problems such as deforestation, biodiversity loss and illegal logging have provoked various policy responses that are often referred to as forest and nature governance. In its broadest interpretation, governance is about the many ways in which public and private actors from the state, market and/or civil society govern public issues at multiple scales. This book takes a fresh perspective on the study of forest and nature governance. Departing from 'practice theory', and building upon scholars like Giddens, Bourdieu, Reckwitz, Schatzki and Callon, it seeks to move beyond established understandings of institutions, actors, and knowledge. In so doing, it not only presents an innovative conceptual and methodological framework for a practice based approach, but also rich case studies and ethnographies. Finally, this book is about how actors involved in governance talk about and work with trees, forests, biodiversity, wildlife, and so on, while acting upon forest policies, environmental discourses, codes of conduct, or scientific insights.
This book traces the economic and biological pattern of forest development from initial settlement and harvest activity at the natural forest frontier to modern industrial forest plantations. It builds from diagrams describing three discrete stages of forest development, and then discusses the management and policy implications associated with each, supporting its observations with examples and data from six continents and from both developed and developing countries. It shows that characteristic distinctions between the three stages make forestry unusual in natural resource management and that effective policy requires different, even contrasting, decisions at each stage. William F. Hyde's comprehensive discussion covers a wide range of issues, including the impacts of both specific forest policies and broader macroeconomic policies, the unique requirements of current issues such as global warming, biodiversity and tourism, and the complexities of the different forest products industries. Concluding chapters review the roles of the newer institutional landowners, of smaller private and farm landowners, and of public agencies. This highly-original volume reaches far beyond forest economics; it explains what forestry can do for regional development and environmental conservation and what policies designed for other sectors and the macro-economy can do for forestry.
Designed to work effectively both as a manual for the logging industry and as a textbook for timber harvesting courses. The sequence of the chapters on logging and associated activities coincides with the consecutive steps in logging - from acquiring the timber through its final transport. This second edition emphasizes environmental considerations - such as the increasing need to reduce excessive soil movement and subsequent siltation.
Urban tree management is the key basis for greener cities of the future. It is a practical discipline which includes tree selection, planting, care and protection and the overall management of trees as a collective resource. Urban Tree Management aims to raise awareness for the positive impacts and benefits of city trees and for their importance to city dwellers. It describes their advantages and details their effects on quality of urban life and well-being aspects that are increasingly important in these times of progressing urbanisation. With this book you will learn: * fundamentals, methods and tools of urban tree management * state of the art in the fields of urban forestry and tree biology * positive effects and uses of urban trees * features, requirements and selection criteria for urban trees * conditions and problems of urban trees * governance and management aspects * environmental education programs. Edited by the leading expert Dr Andreas Roloff, Urban Tree Management is an excellent resource for plant scientists, horticulturists, dendrologists, arborists and arboriculturists, forestry scientists, city planners, parks department specialists and landscape architects. It will be an essential addition to all students and libraries where such subjects are taught.
Wood-pastures are important elements of European cultural identity and have an exceptional ecological value, yet they are in decline all over Europe. The structure of wood-pastures is strongly influenced by grazing and multiple other land uses and by local and regional environmental conditions. This book examines the diverse expressions of wood-pastures across Europe. It provides a new perspective, using a social-ecological framework to explore social and ecological values, governing institutions, threats and conservation approaches. It explores the major drivers of decline, which are shown to be related to accelerated cultural, institutional and developmental changes occurring across Europe over the past century. Case studies are included from North-Western, Southern, and Eastern Europe. Written by renowned scholars and conservationists, the book contributes to developing better, locally adapted conservation policies and management approaches for wood-pastures.
The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today's pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970's studies of atmospheric deposition; the 1980's research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990's investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century's research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who's who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.
An important prerequisite for successful conservation is a good understanding of what we seek to conserve. Nowhere is this more the case than in the fight to protect plant biodiversity, which is threatened by human activity in many regions worldwide. This book is written in the belief that tools that enable more people to understand biodiversity can not only aid protection efforts but also contribute to rural livelihoods. Among the most important of those tools is the field guide. Plant Identification provides potential authors of field guides with practical advice about all aspects of producing user-friendly guides which help to identify plants for the purposes of conservation, sustainable use, participatory monitoring or greater appreciation of biodiversity. The book draws on both scientific and participatory processes, supported by the experience of contributors from across the tropics. It presents a core process for producing a field guide, setting out key steps, options and techniques available to the authors of a guide and, through illustration, helps authors choose methods and media appropriate to their context.
The grove, a grouping of trees, intentionally cultivated or found growing wild, has a long diverse history entwined with human settlement, rural practices and the culture and politics of cities. A grove can be a memorial, a place of learning, a site of poetic retreat and philosophy or political encampment, a public park or theatre, a place of hidden pleasures, a symbol of a vanished forest ecology, or a place of gods or other spirits. Yet groves are largely absent from our contemporary vocabulary and rarely included in today's landscape practice, whether urban or rural. Groves are both literal and metaphorical manifestations, ways of defining spaces and ecologies in our cultural life. Since they can add meaning to urban forms and ecologies and contribute meaningfully to the significance of place, critical examination is long overdue. The editors have taken care to ensure that the text is accessible to the general reader as well as specialists.
Complete with information on buying and selling woods, useful contact addresses and a glossary of terms, Caring for Small Woods will prove the indispensable handbook.
Forests and woodlands provide an enormous range of goods and services to society, from timber and firewood to medicinal plants, watershed protection, destinations for tourists and sacred sites. Only when these are understood and valued can forests and their resources be properly managed and conserved. This work shows how the complicated network of benefits can be untangled and sets out the different approaches needed to value them. It covers the analysis of plant-based markets, non-market valuation and decision frameworks such as cost-benefit analysis.
