Globalisation and Change in Forest Ownership and Forest Use - Natural Resource Management in Transition (Hardcover, 1st ed.... Globalisation and Change in Forest Ownership and Forest Use - Natural Resource Management in Transition (Hardcover, 1st ed. 2017)
E. Carina H. Keskitalo
R4,015 Discovery Miles 40 150 Ships in 10 - 15 working days

This book describes the changing landscape of European forest ownership and explores the impact a new, often urban, generation of forest owners may have on the future of one of our most basic resources - forests. Forests have not played a major role in rural studies thus far, however they constitute an important part of many rural areas. Drawing on Swedish cases and comparison cases from various other areas of Europe, the authors present these 'new forest owners' as a pivotal factor in the changing relationships between urban and rural life. The chapters explore how forest production, the relationship to the environment, urban-rural relations and local communities have already changed as well as discussing what might be expected for the future. A result of work in the Swedish research programme PLURAL and related projects, such as the EU Cost Action FACESMAP, this volume will be of interest to scholars of forestry and rural studies, as well as to researchers in environmental, population and globalization studies more broadly.

Spatial Modelling in Forest Ecology and Management - A Case Study (Hardcover): Martin Jansen, Michael Judas, Joachim Saborowski Spatial Modelling in Forest Ecology and Management - A Case Study (Hardcover)
Martin Jansen, Michael Judas, Joachim Saborowski
R2,882 Discovery Miles 28 820 Ships in 18 - 22 working days

This book focuses on the integration of spatial statistics, GIS-technology, ecosystem studies, and scenario modelling. Its main aim is to extend the information gained at the stand level to larger spatial scales, i.e. to forest districts, forest landscapes or to the total area of Lower Saxony. The studies demonstrate the potential and limitations of regionalization approaches for forest ecological variables. The results provide valuable spatial information for forest managers and landscape planners as well as for policy-makers. Some spatial models outlined in this book have been implemented as useful tools in present forest management. With current improvements of data quality, e.g. from remote sensing and refined ground-based inventories, methods are now available to develop large-scale approaches to forest ecology and management. This book is an indispensable tool for scientists and those involved in forest management.

R5,168 Discovery Miles 51 680 Ships in 18 - 22 working days

Over the last two decades, the topic of forest ecosystem services has attracted the attention of researchers, land managers, and policy makers around the globe. The services rendered by forest ecosystems range from intrinsic to anthropocentric benefits that are typically grouped as provisioning, regulating, supporting, and cultural. The research efforts, assessments, and attempts to manage forest ecosystems for their sustained services are now widely published in scientific literature. This volume focuses on broad-scale aspects of forest ecosystem services, beyond individual stands to large landscapes. In doing so, it illustrates the conceptual and practical opportunities as well as challenges involved with planning for forest ecosystem services across landscapes, regions, and nations. The goal here is to broaden the scope of land use planning through the adoption of a landscape-scale approach. Even though this approach is complex and involves multiple ecological, social, cultural, economic, and political dimensions, the landscape perspective appears to offer the best opportunity for a sustained provision of forest ecosystem services.

Ecosystem Goods and Services from Plantation Forests (Hardcover, New): Jurgen Bauhus, Peter Van der Meer, Markku Kanninen Ecosystem Goods and Services from Plantation Forests (Hardcover, New)

R4,512 Discovery Miles 45 120 Ships in 10 - 15 working days

Plantation forests often have a negative image. They are typically assumed to be poor substitutes for natural forests, particularly in terms of biodiversity conservation, carbon storage, provision of clean drinking water and other non-timber goods and services. Often they are monocultures that do not appear to invite people for recreation and other direct uses. Yet as this book clearly shows, they can play a vital role in the provision of ecosystem services, when compared to agriculture and other forms of land use or when natural forests have been degraded. This is the first book to examine explicitly the non-timber goods and services provided by plantation forests, including soil, water and biodiversity conservation, as well as carbon sequestration and the provision of local livelihoods. The authors show that, if we require a higher provision of ecosystem goods and services from both temperate and tropical plantations, new approaches to their management are required. These include policies, methods for valuing the services, the practices of small landholders, landscape approaches to optimise delivery of goods and services, and technical issues about how to achieve suitable solutions at the scale of forest stands. While providing original theoretical insights, the book also gives guidance for plantation managers, policy-makers, conservation practitioners and community advocates, who seek to promote or strengthen the multiple-use of forest plantations for improved benefits for society.

Degraded Forests in Eastern Africa - Management and Restoration (Hardcover): Frans Bongers, Timm Tennigkeit Degraded Forests in Eastern Africa - Management and Restoration (Hardcover)
Frans Bongers, Timm Tennigkeit
R4,518 Discovery Miles 45 180 Ships in 10 - 15 working days

Forest degradation as a result of logging, shifting cultivation, agriculture and urban development is a major issue throughout the tropics. It leads to loss in soil fertility, water resources and biodiversity, as well as contributes to climate change. Efforts are therefore required to try to minimize further degradation and restore tropical forests in a sustainable way. This is the first research-based book to examine this problem in East Africa. The specific focus is on the forests of Ethiopia, Tanzania and Uganda, but the lessons learned are shown to be applicable to neighbouring countries and others in the tropics. A wide range of forest types are covered, from dry Miombo forest and afromontane forests, to forest-savannah mosaics and wet forest types. Current management practices are assessed and examples of good practice presented. The role of local people is also emphasized. The authors describe improved management and restoration through silviculture, plantation forestry and agroforestry, leading to improvements in timber production, biodiversity conservation and the livelihoods of local people.

Monitoring Forest Biodiversity - Improving Conservation through Ecologically-Responsible Management (Hardcover): Toby Gardner Monitoring Forest Biodiversity - Improving Conservation through Ecologically-Responsible Management (Hardcover)
Toby Gardner
R4,519 Discovery Miles 45 190 Ships in 10 - 15 working days

The fate of much of the world's terrestrial biodiversity depends upon our ability to improve the management of forest ecosystems that have already been substantially modified by humans. Monitoring is an essential ingredient in meeting this challenge, allowing us to measure the impact of different human activities on biodiversity and identify more responsible ways of managing the environment. Nevertheless many biodiversity monitoring programs are criticised as being little more than 'tick the box' compliance exercises that waste precious resources and erode the credibility of science in the eyes of decision makers and conservation investors. The purpose of this book is to examine the factors that make biodiversity monitoring programs fail or succeed. The first two sections lay out the context and importance of biodiversity monitoring, and shed light on some of the key challenges that have confounded many efforts to date. The third and main section presents an operational framework for developing monitoring programs that have the potential to make a meaningful contribution to forest management. Discussion covers the scoping, design and implementation stages of a forest biodiversity monitoring program, including defining the purpose, goals and objectives of monitoring, indicator selection, and the process of data collection, analysis and interpretation. Underpinning the book is the belief that biodiversity monitoring should be viewed not as a stand-alone exercise in surveillance but rather as an explicit mechanism for learning about how to improve opportunities for conservation. To be successful in this task, monitoring needs to be grounded in clear goals and objectives, effective in generating reliable assessments of changes in biodiversity and realistic in light of real-world financial, logistical and social constraints.

Central Amazonian floodplain forests are an unique and endangered ecosystem. The forests grow in areas that are annually flooded by large rivers during mean periods of up to 8 months and at depths of up to 10 m. Despite this severe stress, these forests consist of over 1,000 species and are by far the most species-rich floodplain forests worldwide. The trees show a broad range of morphological, anatomical, physiological, and phenological adaptations that enable them not only to survive the adverse environmental conditions, but also to produce large amounts of biomass when the nutrient levels in water and soils are sufficiently high. This is the case in the floodplains of white-water rivers, which are used for fisheries, agriculture, and cattle-ranching but which also have a high potential for the production of timber and non-timber products, when adequately managed. Latest research on ecophysiology gives insight how tree species adapt to the oscillating flood-pulse focusing on their photosynthesis, respiration, sap flow, biochemistry, phenology, wood and leave anatomy, root morphology and functioning, fruit chemistry, seed germination, seedling establishment, nitrogen fixation and genetic variability. Based on tree ages, lifetime growth rates and net primary production, new concepts are developed to improve the sustainability of traditional forest managements in the background of an integrated natural resource management. This is the first integrative book on the functioning and ecologically oriented use of floodplain forests in the tropics and sub-tropics.It provides fundamental knowledge for scientist, students, foresters and other professionals on their distribution, evolution and phytogeography. "This book is an excellent testimony to the interdisciplinary collaboration of a group of very dedicated scientists to unravel the functioning of the Amazonian Floodplain forests. They have brought together a highly valuable contribution on the distribution, ecology, primary production, ecophysiology, typology, biodiversity, and human use of these forests offering recommendations for sustainable management and future projects in science and development of these unique wetland ecosystems. It lays a solid scientific foundation for wetland ecologists, foresters, environmentalists, wetland managers, and all those interested in sustainable management in the tropics and subtropics."

During the 1970s and 1980s, Sitka spruce (Picea sitchensis, Bong. Carr. ) was planted extensively on northern Vancouver Island (B. C. , Canada) to regenerate slashburned clearcuts previously occupied by old-growth Thuja p1icata, Donn, Tsuga heterophy11a, Raf. Sarg. , and an ericaceous unders tory shrub salal (Gaul ther ia sha11on, Pursh [CH sites 1 ) . The planted Sitka spruce grew well initially on these sites, but experienced nutritional stress and reduced growth 8 to 14 yr after planting (Germain, 1985; Weetman et a1. , 1990a,b). Accompanying the onset of the nutritional stress was the reestablishment of a complete ground cover of salal, and it has been suggested that there is a causal connection between these two temporally synchronous events (Weetman et al. , 1990a,b). Other ericaceous species have been implicated in nutritional stress in conifer plantations (Mallik, 1987; Robinson, 1972; Handley, 1963; Rose et a1. , 1983). Three hypotheses to explain this nutritional stress were tested in the study reported in this paper: (1) that salal competition for N can provide an adequate explanation for the observed nutritional stress; (2) that salal inhibits the availability of nutrients to seedlings by interfering with their mycorrhizae; and (3) that the fertility of these CH sites declines after 8 yr following clearcutting and slashburning due to the termination of the flush of nutrients (or "assart effect") associated with this disturbance. A series of pot and field experiments was carried out to test these hypotheses. 1 2.

Forensic Forestry - A Guidebook for Foresters on the Witness Stand (Hardcover): Robert P. Latham Forensic Forestry - A Guidebook for Foresters on the Witness Stand (Hardcover)
Robert P. Latham
R4,486 Discovery Miles 44 860 Ships in 10 - 15 working days

Forensic Forestry: A Guidebook for Foresters on the Witness Stand is a one-of-a-kind, hands-on resource for those forestry and land use professionals called upon to work on legal cases and testify in court. Land use and forestry issues in the United States, in particular-and likewise around the world-have become increasingly contentious, scrutinized, and debated. There is little to suggest that conflicts over forestlands will cease in the near future, in fact, quite the opposite. There are already a number of informative books available on land use and forestry, and related issues under the broader heading of environmental science. As such, while this book will not go into these concepts in detail, if someone is already an expert in land use and forestry, this book will tell them the ins and outs of the legal system and how they can best serve to make a case, using evidence, in a court of law. Coverage addresses the necessary background, and legwork involved, in providing technical expertise for such cases to be adjudicated. Since professionals' expertise is often focused on ecological issues, chapters look at the economic factors and how money, policy, and corporate interests come into play-the crux of where the professional forester's ability to present evidence and expertise becomes critical. The author provides an overall understanding of the courts, and the legal process. Coverage includes recommendations to professionals working on cases-and in the courtroom-in how to present evidence and testify in cases over land use and forestland rights, forestry management and safety, criminal and civil cases in liability in forest fires-among myriad others. Key Features: A book by a professional for professionals in the field of forestry and those called to testify in cases of forest and wildfires, eminent domain, land disputes, tort, and liability cases Written in easy-to-read, non-technical jargon to provide tools to best serve as an expert witness and consultant to support attorneys in civil and criminal cases Details unique, real-world cases study examples, detailing how they were adjudicated based on evidence and testimony provided Presents a legal background into the court system, courtroom procedure, the types of legal cases as they relate to forensic forestry As such, Forensic Forestry is a welcome addition to those professionals called upon to consult on, and testify in, such cases including land use professionals, foresters and forestry managers, ecologists, environmentalists, environmental policy advocates, and those in related fields.

R2,795 Discovery Miles 27 950 Ships in 10 - 15 working days

The economic value of forest. has long been recognized, but the ways in which that value is calculated and the management policies adopted in consequence have all too often resulted in overuse and irreversible destruction. This is spectacularly obvious around the Mediterranean basin, but it is also true in northern Europe. These five case studies, commissioned by the OECD, examine failures of forest management in Britain, Spain, Italy, Germany and Sweden. They look at both market and intervention policies and show how each can further the destruction of the forests, and they set out ways in which future policies can evade the mistakes of the past.

R780 Discovery Miles 7 800 Ships in 10 - 15 working days

New ideas in ecology have implications for managing forest ecosystems. The discipline of silviculture is at a crossroads. Silviculturists are under increasing pressure to develop practices that sustain the full function and dynamics of forested ecosystems and maintain ecosystem diversity and resilience while still providing needed wood products. "A Critique of Silviculture" offers a penetrating look at the current state of the field and provides suggestions for its future development.The book includes an overview of the historical developments of silvicultural techniques and describes how these developments are best understood in their contemporary philosophical, social, and ecological contexts. It also explains how the traditional strengths of silviculture are becoming limitations as society demands a varied set of benefits from forests and as we learn more about the importance of diversity on ecosystem functions and processes.The authors go on to explain how other fields, specifically ecology and complexity science, have developed in attempts to understand the diversity of nature and the variability and heterogeneity of ecosystems. The authors suggest that ideas and approaches from these fields could offer a road map to a new philosophical and practical approach that endorses managing forests as complex adaptive systems."A Critique of Silviculture" bridges a gap between silviculture and ecology that has long hindered the adoption of new ideas. It breaks the mold of disciplinary thinking by directly linking new ideas and findings in ecology and complexity science to the field of silviculture. This is a critically important book that is essential reading for anyone involved with forest ecology, forestry, silviculture, or the management of forested ecosystems.

Hitoshi Sakio
R1,535 Discovery Miles 15 350 Ships in 18 - 22 working days

This open access book presents and analyzes the results of more than 30 years of long-term ecological research in riparian forest ecosystems with the aim of casting light on changes in the dynamics of riparian forests over time. The research, focusing on the Ooyamazawa riparian forest, one of the remaining old-growth forests in Japan, has yielded a number of interesting outcomes. First, it shows that large-scale disturbances afford various trees opportunities for regeneration and are thus the driving force for the coexistence of canopy trees in riparian forests. Second, it identifies changes in reproductive patterns, highlighting that seed production has in fact quantitatively increased over the past two decades. Third, it describes the decline in forest floor vegetation caused by deer grazing and reveals how this decline has affected bird and insect populations. The book illustrates the interconnectedness of phenomena within an ecosystem and the resultant potential for cascade effects and also stresses the need for long-term ecological studies of climate change impacts on forests. It will be of interest to both professionals and academics in the field of forest science.

Addresses One of the Supreme Threats to Biodiversity

As the worldwide human population explodes and trade becomes increasingly globalized, the transboundary movement of plant species from their place of origin to foreign regions is escalating and expected to experience continued growth in the coming decades. Invasive Plants and Forest Ecosystems takes an informed and integrated approach to the current onslaught of invasive species, spotlighting the tremendous challenges they pose for natural resource managers charged with the maintenance of biological diversity and the sustainable production of forest wealth. It addresses the havoc these alien invaders are wrecking on native forest ecosystems and the staggering $300 billion annually in damage and control costs they incur.

An Up-to-Date Synthesis of Invasive Plants, Their Impact, and Control Strategies

Examining invasion ecology through both synthesis and original research chapters, this compilation gives a bird's eye view of the ecological impact alien invaders have both in temperate and tropical climates. With internationally recognized contributors, this text explores the socioeconomic and policy aspects of adaptive collaborative management strategies that are crucial to controlling alien invasive plants. This book successfully captures the current state of knowledge surrounding this fast-growing ecological issue, making it an indispensable resource for those committed to the protection of global forestry and natural resources.

R4,503 Discovery Miles 45 030 Ships in 10 - 15 working days

The decentralization of control over the vast forests of the world is moving at a rapid pace with both positive and negative ramifications for people and forests themselves. This new book, by leading researchers from the Center for International Forestry Research (CIFOR), presents the latest research into decentralization in the forests of Asia and the Pacific, unraveling the complex issues at stake. Fresh research from a host of Asia-Pacific countries including India, Nepal, China, Korea, Indonesia, Laos, Malaysia, Philippines and Vietnam among others, presents the authors' rich and varied experience with decentralization and provides important lessons for other regions. The book begins with historical and geographical overview chapters, proceeding to more in-depth coverage in the region's countries. Research findings stress rights, roles and responsibilities, on the one hand, and institutions including organization, capacity building, infrastructure and legal aspects, on the other. With these overarching themes in mind, the authors take on many controversial topics, examining inclusiveness in decision-making, justice and equity, criminal activity such as illegal logging and corruption, land use including rehabilitation and tenure, policy-practice gaps, community forestry, implications for household economies and environmental impacts such as fire. Several authors also address practical challenges related to financing and reinvestment in sustainable forest management under decentralized governance. Particular efforts have been made to examine decentralization at various scales from local to national and to address gender issues, which have previously been largely ignored in thedecentralization discussions. The result is a unique examination of decentralization issues in forestry with clear lessons for policy, forest management, research, development and conservation in forested areas across the globe from the tropics to temperature regions.

Faced with the growing problems of climate change, ecosystem degradation, declining agricultural productivity, and uncertain food security, modern agricultural scientists look for potential relief in an ancient practice. Agroforestry, if properly designed, can mitigate greenhouse effects, maintain ecosystem health and biodiversity, provide food security, and reduce poverty. Poorly implemented agroforestry, however, can not only exacerbate existing problems, but also contribute in its own right to the overall negative effects of our depleted and failing ecosystems. With a diminishing margin for error, a thorough understanding of the ecological processes that govern these complex systems is, therefore, crucial. Drawing on the collective expertise of world authorities, Ecological Basis of Agroforestry employs extensive use of tables and figures to demonstrate how ecologically sustainable agroecosystems can meet the challenges of enhancing crop productivity, soil fertility, and environmental sustainability. Divided into four sections, this comprehensive volume begins with a study of tree-crop interaction in tropical and temperate climates. Contributions cover above and below ground interactions, alley cropping, tri-trophic interactions, ecologically based pest management, and the chemistry and practical potential of chemically mediated plant interactions. The second section investigates root-mediated below ground interactions and their role in enhancing productivity, soil fertility, and sustainability. It includes an extensive study on litter dynamics and factors affecting nutrient release. Applying ecological modeling of complex agroforestry systems, section three demonstrates the use of computer-based designs to ensure profitability. The final section addresses the socio-economic aspects of agroforestry, supplying in-depth knowledge of various farming systems and discussing the technological tools that benefit society in different eco-regions around the world.

The chemicals from plant sources, generally termed as phytochemicals, play an important role in acceptance or rejection of the plant by the pests as they could be distasteful or toxic on one hand or on the other hand specialist herbivores have the capability to feed on many such chemicals, as they are able to process these natural products in a manner that is beneficial to them. In the wake of increasing environmental degradation due to burgeoning synthetic chemicals, there has been a process going on to rediscover the usefulness of plants and herbs and a continued effort for more than 2 decades has been to study the green products for cures for several ailments and pest management. In fact, according to Indian Medicinal Plants: A Sectoral Study, the global trade for medicinal plants amounts to about US $ 60 billion and the world demand continues to grow at the rate of 7 per cent per annum. Although many such plants are known in literature, neem has been one of trees with mani-fold virtues. Indian neem tree, Azadirachta indica A. Juss, which is a large evergreen tree, is an outstanding example among plants that has been subject matter of numerous scientific studies concerning its utilization in medicine, industry and agriculture. So far neem preparations have been evaluated against more than 500 species of insects and more than 400 hundred are reported to be susceptible at different concentrations.

Biological nitrogen fixation (BNF) - the conversion of molecular nitrogen into ammonia - is one of the most important reactions in ecology and agriculture. It is performed exclusively by microbes (prokaryotes) that live in symbiosis with plants. This book summarizes the latest research on this reaction, the participating microbes and the genetics of how their relevant genes could be transferred into the plants. In the light of a more sustainable and less ecologically damaging agriculture, this is becoming an increasingly pressing issue.

This is a handbook on the subject of crop pests. Including 288 colour photographs, the book contains information which has been edited and updated from the series of advisory leaflets issued by the Ministry of Agriculture, Fisheries and Food (MAFF) which have been a widely acknowledged source of valuable information for many years. Much of the information, which has been revised by entomologists of the Agricultural Development Advisory Service (ADAS), should be of interest in other countries of Northern Europe and throughout temperate regions of the world. The book contains descriptions of the pests, their life histories, the damage they cause, their natural enemies and the strategies for control. The demand for the continued availability of the wealth of knowledge and practical experience originally incorporated into the MAFF leaflets has prompted the publication of this book. This publication should be a useful handbook for all those involved with applied entomology and crop protection, particularly agricultural and horticultural students, crop consultants and advisers, those working in the agrochemical industry and proficient farmers, growers and entomologists.

Ecology of Fire-Dependent Ecosystems is brimming with intriguing ecological stories of how life has evolved with and diversified within the varied fire regimes that are experienced on earth. Moreover, the book places itself as a communication between students, fire scientists, and fire fighters, and each of these groups will find some familiar ground, and some challenging aspects in this text: something which ultimately will help to bring us closer together and enrich our different approaches to understanding and managing our changing planet. -- Sally Archibald, Professor, University of the Witwatersrand, Johannesburg, South Africa Most textbooks are as dry as kindling and about as much fun to sink your teeth into. This is not that kind of textbook. Devan Allen McGranahan and Carissa L. Wonkka have taken a complex topic and somehow managed to synthesize it into a comprehensive, yet digestible form. This is a book you can read cover to cover - I know, I did it. As a result, I took an enlightening journey through the history and fundamentals of fire and its role in the natural and human world, ending with a thoughtful review of the evolving relationship between humans and wildland fire. -- Chris Helzer, Nebraska Director of Science, The Nature Conservancy, and author of The Prairie Ecologist blog Ecology of Fire-Dependent Ecosystems: Wildland Fire Science, Policy, and Management is intended for use in upper-level courses in fire ecology and wildland fire management and as a reference for researchers, managers, and other professionals involved with wildland fire science, practice, and policy. The book helps guide students and scientists to design and conduct robust wildland fire research projects and critically interpret and apply fire science in any management, education, or policy situation. It emphasizes variability in wildland fire as an ecological regime and provides tools for students, researchers, and managers to assess and connect fire environment and fire behaviour to fire effects. Fire has not only shaped social and ecological communities but pushed ecosystems beyond previous boundaries, yet understanding the nature and effects of fire as an ecological disturbance has been slow, hampered by the complexity of the dynamic interactions between vegetation and climate and the fear of the destruction fire can bring. This book will help those who study, manage, and use wildland fire to develop new answers and novel solutions, based on an understanding of how fire functions in natural and social environments. It reviews literature, synthesizes concepts, and identifies research gaps and policy needs. The text also explores the interaction of fire and human culture, demonstrating how fire policy can be made adaptable to cultural and socio-ecological objectives.

Remote sensing and GIS are increasingly used as tools for monitoring and managing forests. Remotely sensed and GIS data are now the data sources of choice for capturing, documenting, and understanding forest disturbance and landscape pattern. Sitting astride the fields of ecology, forestry, and remote sensing/GIS, Understanding Forest Disturbance and Spatial Pattern: Remote Sensing and GIS Approaches takes you through the general biological or landscape ecological context of forest disturbance to remote sensing and GIS technological approaches and pattern description and analysis, with compelling applied examples of integration and synthesis. Written by experts, peer-reviewed to adhere to the strictest standards and highest quality criteria, these chapters discuss natural and human-caused forest change and consider factors such as biological setting, monitoring approaches, scale issues, and pattern analysis. The book explores forest disturbance and spatial pattern from an ecological point-of-view within the context of structure, function, pattern, and change. It concludes with a summary of the issues related to detection and mapping of forest disturbances with remotely sensed and GIS data. The authors elucidate how the elements presented, from ecological underpinnings, data considerations, change detection method, and pattern analysis, combine into a problem solving, information generating approach. You may find this subject covered briefly in a small sub-section in remote sensing forestry texts, or in limited technical detail in the ecology literature. The in-depth, detailed information provided in this book allows you to develop an understanding of the application of BOTH remote sensing and GIS technologies to forest change and the impacts of fire, insect infestation, forest harvesting, and other potential change influences - such as extreme weather events. This book provides guidance on how to master the challenges of capturing and characterizing forest disturbance and spatial patterns.

Timber sourcing is shifting from extraction from natural forests to forms of cultivation that are increasingly agricultural in nature. This book takes a multidisciplinary approach to examine the socio-political, biophysical and discursive dimensions of this divergence of wood production from forests. This analysis challenges the historical integration of wood production and forest ecosystem management exemplified by the institutions of forestry with their inherent wood/forest connection. This has significant implications for how wood and forest socio-ecological systems confront change and challenge ideas about how to achieve sustainability. Historically, the institutions of stewardship forestry were founded on ideals of sustainable systems in long-term equilibrium. However, these occur within rapidly evolving social and technological contexts that constantly challenge the maintenance of any equilibrium. This creates considerable tension within wood and forest socio-ecological systems and their institutions and governance. Moving beyond adaptation to transformation, however, requires a willingness to consider post-forestry conditions, such as integration of emerging wood cultivation systems into agricultural and landscape approaches, and increasing management of extensive forest ecosystems for non-wood values in the absence of wood production. This book includes four case studies: a global modelling of shifts in wood production and three national case studies (Australia, Indonesia and New Zealand), each analysing shifts in resilience in wood and forest socio-ecological systems using a different disciplinary approach. This book will be of interest to advanced students, researchers and professionals in forestry, land use, conservation, rural studies and geography.
