Bio-based materials, including those containing wood, will become increasingly important as we move to a bio-based economy. Among their many attributes, it is vitally important that these materials are renewable, sustainable with proper management and environmentally benign. Wood remains one of our most important bio-based materials. While it is an amazing material, wood still has negative attributes and drawbacks that can affect performance, including dimensional instability when wetted, vulnerability to fire and high temperatures, and susceptibility to biodeterioration. A variety of treatments have been developed to overcome these weaknesses. Among the most exciting of these treatments are nanomaterials. These materials have some exceptionally attractive properties for improving timber performance and have been the subject of intensive research over the past decade. There is a tremendous need for a single comprehensive source of information on this rapidly emerging subject with tremendous potential to enhance the performance of a variety of bio-based materials. This book contains 10 chapters, each compiled by different author(s) who are considered the top researcher(s) in their respective fields. The chapters begin with some basic background on nanomaterials and their synthesis, then explore different areas for potential applications and conclude with a review of the emerging questions about nanomaterial safety. The book is designed to provide the latest information and know-how on application and utilization of different nanomaterials to improve the properties of wood and wood-based composite panels. The contents cover some main topics in the industry including improving physical and mechanical properties, increasing resistance to biodegradation (including fungi and insects), developing wood-plastic composites (WPC), applying nanomaterials in paper and board industry, and emergence of transparent wood and radiation shielding. It also covers the use of nanomaterials to improve the performance of paints and finishes used for forest products. The book provides a single location for those interested in the field to begin.

Science of Wood Degradation and its Protection (Hardcover, 1st ed. 2022): R. Sundararaj Science of Wood Degradation and its Protection (Hardcover, 1st ed. 2022)
R. Sundararaj
R6,625 Discovery Miles 66 250 Ships in 10 - 15 working days

This edited book covers all aspects of wood degradation from its formation and growing in trees to its end usages when it is put into human usage. Wood is an age-old traditional fascinating material with a sensory-rich immersive experience that kindles aesthetics and creativity. The utility, durability, and functionality of wood render it a cosmopolitan material. It constitutes an integral part of human lives from ancient times to modern societies being used by various sectors viz., construction, furniture, panel products, paper and pulp, sports goods, agricultural implements, etc., Wood, being a biological material, is susceptible to degradation both by physical and biological means, and the need to protect the wood and prevent heavy economic losses constitutes a major challenge. Also, wood formed by the trees is the major sinks of carbon and the carbon remains locked-up for the life of the wood, thereby serving as important tool to mitigate the climate change. But the carbon stored in wood returns to the atmosphere when it degrades and will have positive effect on climate change. Hence, wood protection aiming for extending the service life of wood plays a key role in locking the carbon for a longer period in the wood and also substantially reduce the demand and depletion of forest resources. The book focuses on wood as an important natural bio-resource, inventory of wood protection, usage, utilization, preservatives, protection technologies and wood protection from all forms of degradation. Special focus is given on the eco-friendly way of protecting wood and its importance in mitigating climate change. The book is useful for Indian and international readers, who are working in wood domains. It is of interest to wood technologists, teachers, researchers, climate change scientists, capacity builders, and policymakers. It is of immense importance as a guide and study material to the graduate and postgraduate students of wood science in various universities of India and abroad.

Nature Law and Policy in Europe (Paperback): Andrew Jackson Nature Law and Policy in Europe (Paperback)
Andrew Jackson
R1,358 Discovery Miles 13 580 Ships in 9 - 17 working days

This volume considers current and future challenges for nature law and policy in Europe. Following the Fitness Check evaluation of the Birds and Habitats Directives, in 2017 the EU adopted an Action Plan for nature, people and the economy to rapidly improve the Directives' implementation and accelerate progress towards the EU's biodiversity targets for 2020. More recently, the EU has adopted a Biodiversity Strategy for 2030 and proposed an EU Nature Restoration Law. This book makes a timely contribution by examining the current state of play in light of recent and historical developments, as well as the post-2020 nature law and policy landscape. While evidence suggests that Natura 2000 and the Habitats and Birds Directives have delivered conservation benefits for wildlife in Europe, biodiversity loss continues apace. The book reviews the requirements for an effective international nature conservation system, with reference to the Birds and Habitats Directives. It examines regulatory regimes, current legal issues in the fields of site protection and species protection, the protection of areas outside Natura 2000, recent developments in the EU and the UK, including the implications of Brexit, agriculture and nature conservation, litigation, science and access to justice. Written by leading experts in the field, from a range of stakeholder groups, the volume draws on diverse experiences as well as providing interdisciplinary perspectives. This volume will be essential reading for students and scholars interested in European environmental policy and law, including lawyers, ecologists, environmental scientists, political scientists, natural resource managers, and planners. It will also be of interest to conservation practitioners, policy-makers and NGOs.

A valuable working resource for professionals.
An excellent text for advanced forestry students . . .
This unique book provides students and professionals with a broad- based knowledge of contemporary silviculture theory and practice. Throughout, the authors emphasize fundamental questions of edaphic, physiographic, and climatic site factors, as well as ecological relationships and silvical characteristics of major tree species. Updated and expanded to reflect the many scientific, socioeconomic, and public policy trends that have had a profound impact on silviculture over the past decade, this Third Edition of Regional Silviculture of the United States:
* Brings together the knowledge and expertise of fourteen leading experts from around the nation
* Provides a rational framework with which to critically assess forest data and to develop innovative silvicultural solutions
* Features region-by-region coverage of the eleven major forest types in the continental U.S. and Alaska
* Offers a detailed look at practices that promote a wide range of forest resources--from wood production and outdoor recreation, to wildlife habitat and range forage production
* Now includes more in-depth coverage of such crucial themes as biodiversity, endangered species, habitat fragmentation, forest health, landscape management, neotropical migrants, and more

..".silviculture is not reducible to a series of rules; it must be flexible and adaptable to a variety of conditions. Much of it is an art as well as a synthesis of ecology and economics. There is no single best answer to how a stand should be managed. And institutional and societal constraints must be considered." --from the Preface by John W. Barrett
Regional Silviculture of the United States, Third Edition is not a "cookbook,"offering pat recipes for solving "typical" silvicultural problems. Instead, it arms those responsible for the development and care of forests with something far more valuable--a rational framework for the analysis of forest data and the development of innovative solutions tailored to specific forest types and the shifting politicoeconomic constraints under which silviculturalists must work.
One way in which this book achieves that goal is by providing readers with a broad-based knowledge of contemporary silviculture theory and practice. In chapters organized according to the eleven major forest regions of the continental U.S., fourteen recognized experts from around the nation--each of them a specialist in a particular region of operation--offer their valuable insights and observations on silviculture in general and on various silvicultural practices with which they are familiar. Throughout, the authors are attentive to fundamental considerations of edaphic, physiographic, and climatic site factors, as well as ecological relationships and silvical characteristics of major tree species.
This Third Edition of John W. Barrett's classic has been revised and expanded to encompass a number of important themes which have risen to prominence within silviculture over the past decade, including biodiversity, endangered species, habitat fragmentation, forest health, landscape management, and neotropical migrants.
Timely, authoritative, and comprehensive in scope, Regional Silviculture of the United States, Third Edition is a valuable resource for foresters, forestry students, ecologists, environmental scientists, and all those concerned with development, management, and preservation of our most valuable national treasure.

This open access book deals with the methods and the results of the third Italian national forest inventory (INFC2015). Arma dei Carabinieri is entrusted with the realisation of the National Forest Inventory and with the decisions about the aims of the survey and data treatment. National forest inventories produce statistically based information on forests over country areas. Such information is used either at subnational or at supranational level in a great number of spheres and processes, included possibility to depict the status of the world forests. Italy conducted its first forest inventory in 1985 and in 2001 a permanent national forest inventory was launched to have periodically updated statistics. Due to the growing concern about the environment and especially the climate change, estimating forests carbon pools was a stated main objective and it was accordingly named Italian National Inventory of Forest and Forest Carbon Pools (INFC). The book begins with a description of the general organisation, the definitions, the methods and the estimation procedures. It proceeds showing the main estimates produced by INFC2015, in tables that are given in the book chapters. The estimates are presented through texts that introduce the subject matter, explain the way the related variables were surveyed and comment on the main outcomes with the help of graphics. The estimates presented include forest area, management and production, biodiversity and protection, forest health, protective and socio-economics functions. Role of forest in the carbon balance was analysed in a specific Chapter, as this is important for its role in the climate change mitigation. The book ends providing an understanding of the current dynamics of Italian forests by comparing the estimates obtained from INFC2005 and INFC2015, the last two national surveys.

Most forest tree species were considered recalcitrant a decade ago, but now with the improved in vitro techniques some progress has been made towards culture-of tree species. Micro propagation has been achieved from the juvenile tissues of a number of forest tree species. On the other hand, tissues from most mature trees are still very difficult to grow and differen tiate in vitro. Nevertheless, there has been slow but steady progress in the application of tissue culture technology for culture of tissues, organs, cells and protoplasts of tree species. As compared to most agricultural crops, and herbaceous plant species, trees are a different lot. They have long gene ration cycles. They are highly heterozygous and have a large reservoir of genetic variability. Because of this genetic variability, their response in vitro is also variable. On a single medium, the response of tissues from different trees (genotypes) of a single species may be quite different: some responding by induction of growth and differentiation, while others showing minimal or no growth at all. That makes the somatic cell genetics of woody plants somewhat difficult, but at the same time interesting."

R5,297 Discovery Miles 52 970 Ships in 10 - 15 working days

This book brings together comprehensive multi-disciplinary knowledge on diverse aspects of the Himalayan treeline ecotone which is considered one of the most sensitive ecosystems to climate change. The contents of this book are based on the results of extensive research and provide a holistic understanding of the treeline ecotone in Himalaya. The book will serve as an important reference manual and a textbook on treeline ecology. The book is unique in the sense that it provides an engaging account of almost all the aspects of the treeline ecotone, such as taxonomic, functional and phylogenetic species diversity, temperature lapse rates, tree phenology, water relations, and stress physiology, tree ring width chronology, and climate relationships and the role of treeline ecotone in human sustenance in the Indian Himalayan region The treelines in the Himalaya, being the highest in the Northern Hemisphere (up to 4900 m), are among the least investigated systems and hence this book is timely and fills all-important knowledge gaps vis-a-vis treeline shifts, physiognomic, structural, and functional changes in mountain landscapes and ecosystems, particularly under the changing climate This book, for the first time, summarizes evidence-based knowledge about various aspects of treeline ecotone in Himalaya that was largely generated through a well-coordinated a team science approach. The book will be of interest to ecologists, climatologists, dendrochronologists, foresters, plant physiologists and resource managers and policy planners for a better understanding of the organization and dynamics of this fragile ecosystem in relation to climate change and other anthropogenic stresses that are rampant in the Himalaya. The book lays a solid foundation for further investigation of the ecology and dynamics of the treeline ecotone in the Himalayas and provides a rationale for pursuing a team science approach for macroecological investigations.

R3,006 Discovery Miles 30 060 Ships in 10 - 15 working days

This book presents an analysis of forest politics that employs a broader scope to include non-institutionalized actors. It offers a comparative perspective on various environmental social movements fighting to protect forests around the globe, including indigenous communities in the Amazon and eco-anarchists in Europe. By examining the political goals, motives, and tactics of these sometimes-radical environmentalists, it helps readers understand the commonalities and differences among these "grass-roots forest politicians." In addition, the book highlights the importance of forest-related struggles for a just transition to a carbon-neutral future. Accordingly, it will appeal to scholars of political science, public policy, and political sociology, as well as anyone interested in social movements and forest conservation.

The idea for this book arose in 1993, after the Free State of Bavaria through its Bayrisches Staatsministerium rur Landesentwicklung und Umweltfragen (Bavarian Ministry of Regional Development and the Environment) decided to discontinue both the Bavarian project management (PBWU) for forest decline research and the multidisciplinary field research on the Wank Mountain in the Alps near Garmisch. Forest decline through the action of ozone and other photooxidants was a main topic of the supported re search in the Alps and will be a topic of new investigations in the Bavarian Forest. Many interesting results were obtained, but the researchers involved have not had sufficient time to allow reliable conclusions to be drawn. It was therefore decided to ask inter national experts for contributions in order to summarize the best available evidence of a possible link between ozone and forest decline - a topic which has been studied in the USA since the late 1950s and in Europe since the early 1980s. The original idea of Waldsterben as an irreversible large-scale dieback of forests in Germany was soon recognized to be wrong (Forschungsbeirat 1989). However, the new criteria used for the official German and European damage inventories (loss or yel lowing of needles or leaves, tree morphology) indicate that per sistently high percentages of damaged spruce and pine remain, and there is an increasing percentage of damaged beech and oak, with a high proportion of biotic disease (Forschungsbeirat 1989; UN-ECE 1995).

The rapid progress on somatic embryogenesis and its prospects for potential application to improving woody plants prompted us to edit this book initially in three volumes, and now an additional three more volumes. We were all convinced that such a treatise was needed and would be extremely useful to researchers and students. This volume 6 is dedicated to Prof. Harry Waris, Helsinki, Finland, who did pioneer work on somatic embryogenesis during the time when Prof. Steward and others were actively engaged in this area. His former student Prof. Liisa Simols, University of Helsinki, Finland, has written a dedication Harry Waris, a pioneer in somatic embryogenesis' to her teacher Prof. Waris. This volume is divided into three sections and contains a total of 26 chapters. Section A comprises seven chapters covering topics such as: Historical insights into some contemporary problems in somatic embryogenesis (SE); Thin cell layer for somatic embryogenesis induction in woody trees; SE in tropical fruit and forest trees; SE in fruit and forest arid trees; Status of SE in Indian forest trees; SE research in fruit trees in India; Applications of SE for the improvement of tropical fruit trees. Section B comprises 15 chapters, dealing with: SE in oil palm, hazelnut (Corylus avellana L.), pistachio (Pistacia vera L.), Araucaria angustifolia, Quercus suber, Aspidosperma polyneuron, Acacia senegal, Simmondsia chiensis, Cupressus sempervirens, pecan (Carya illinoinensis), rattan (Calamus spp.), tamarillo (Cyphomandra betacea, longan (Dimocarpus longan Lor.), Aegle marmelos, and Euonymus europaeus. Section C comprises three chapters related to cryo-storage of citrus, conifers and rubber. All the chaptershave been peer-reviewed and revised accordingly to improve the quality of the chapters. We are thankful to all: (a) contributory authors for their co-operation in submitting manuscripts in time, and (b) reviewers for spending their valuable time in reviewing the manuscripts.

If one were forced to use a single key word to describe the decade of the 1980's, a very prominent one would be "technology. " Leading the forefront of tech nology advancement were breakthroughs in electronics. Devices that were uncommon or unknown in 1980 became commonplace, and almost indispens able, by 1989. This trend has continued into the 1990's and it does not seem to be abating in any way. Microwave ovens, video recorders, telephone answer ing machines, compact disc players, computers, and a host of smaller or less sophisticated devices now appear in most households. The development of small and inexpensive computers, i. e., personal computers, has placed computing resources within reach of many more people. In addition, many traditional, and largely mechanical devices, have been enhanced by electronics. For example, specialized microprocessors are combined with arrays of electronic sensors to control and monitor sophisticated engineering components in most new auto mobiles. In this and many other ways, we are touched by the new electronics in almost every aspect of our daily lives. Initially, personal computers were little more than toys. They contained only a small fraction of the computing power of their immediate ancestors, the mini computers and mainframe computers. However, rapid improvements in integ rated circuit design and chip manufacture produced regular reductions in size and cost of computer components. During the same time, processor speed and sophistication increased."

Building on more than a decade of innovative research into multi-source forest inventory (MS-NFI) this book presents full details of the development, outputs and applications of the improved k-NN method. The method, which was pioneered in Finland in 1990, is rapidly becoming a world standard in forest inventory, having been adopted as standard in Finland and Sweden, and recently introduced in Austria and across the US.

The book describes in detail the full MS-NFI process, and the input data used - including field data, satellite images, and digital map data, as well as coarse-scale variation of forest variables. It also presents comprehensive information on the types of outputs which can be derived, including maps and statistics, describing, for example, stock volumes and development, dominant tree species, age-class distribution, and large and small-scale variation.

The book will provide an invaluable resource for those involved in forest inventory, including government departments and bodies involved in forest policy, management and monitoring, forest managers, and researchers and graduate students interested in forest inventory, modelling and analysis. It will find an additional market among those interested in Earth observation, ecology and broader areas of environmental and natural resource management.

Erkki Tomppo was the winner of the 1997 Marcus Wallenberg Prize for his work on the k-NN method.

The goal of this Third Edition is to update long-term data presented in earlier editions and to generate new syntheses and conclusions about the biogeochemistry of the Hubbard Brook Valley based on these longer-term data. There have been many changes, revelations, and exciting new insights generated from the longer data records. For example, the impact of acid rain peaked during the period of the HBES and is now declining. The longer-term data also posed challenges in that very marked changes in fluxes occurred in some components, such as hydrogen ion and sulfate deposition, calcium and nitrate export in stream water and biomass accumulation, during the almost 50 years of record. Thus, presenting "mean" or "average" conditions for many components for such a long period, when change was so prominent, do not make sense. In some cases, pentads or decades of time are compared to show these changes in a more smoothed and rational way for this long period. In some cases, a single period, often during periods of rapid change, such as acidification, is used to illustrate the main point(s). And, for some elements a unique mass balance approach, allowing the calculation of the Net Ecosystem Flux (NEF), is shown on an annual basis throughout the study.

Interest in the biology of parasitic flowering plants has been increasing over the past decade, both through it desire to understand the functional biology of these organisms and because of the devastating effects they can have on agricultural crops. This multi-authored book focuses on recent advances in our knowledge of parasitic plants, synthesising information from a wide range of sources. The editors have drawn together an extremely impressive list of international contributors, each an expert in the topics covered, which include seed germination and host penetration, molecular biology and evolution, water/mineral/carbon relations of parasites and their hosts, growth and reproductive ecology, host plant responses to parasitism, parasitic plants as weeds and their control. This important new book will be of great value to upper level undergraduate students and professional ecologists, agriculturists, plant scientists, plant physiologists, crop protection personnel, agrochemical companies and any researcher working with plants.

This book, the result of the author's experience in psychology and forestry studies, studies the relation between these two seemingly different disciplines. The author indicates how human actions and programs affect a range of threatened or endangered situations ranging from forests and species of animals to our own traditional values and cultural groups. Sustainers, the persons who advocate and support sustainability, possess or must come to possess certain characteristics that are shown to be renunciation, knowledge, attitude, controllability, and patterning. This book seeks to discover and advocates how and why those attributes must be strengthened if we are to sustain our environment and ourselves.

R4,782 Discovery Miles 47 820 Ships in 18 - 22 working days

This book collects wide-ranging contributions such as case studies, reviews, reports on technological developments, outputs of research/studies, and examples of successful projects, presenting current knowledge and raising awareness to help the agriculture and forestry sectors find solutions for mitigating climate variability and adapting to change. It brings the topic of ecosystem services closer to education and learning, as targeted by the Framework Convention on Climate Change and the Paris Agreement, the 2030 Agenda for Sustainable Development and the EU Biodiversity Strategy to 2020. Climate change and its impacts on agriculture and agroforestry have been observed across the world during the last 50 years. Increasing temperatures, droughts, biotic stresses and the impacts of extreme events have continuously decreased agroforestry systems' resilience to the effects of climate change. As such, there is a need to adapt farming and agroforestry systems so as to make them better able to handle ever-changing climate conditions, and to preserve habitats and ecosystems services.

The groundnut (peanut) is a crop of global economic significance, not only in the widespread geographical areas of its production, but also in the even wider areas of its processing and consumption. In this extremely important book, the crop is presented in its global context by an international group of contributors. Every chapter has been written by acknowledged experts in each of the major aspects of the crop covered. The book's contents include coverage of the economic status of the groundnut and the origin and history of its cultivation. The crop's botany, taxonomic status and agronomic aspects are covered, including pests and diseases, and thorough coverage is given to the utilization, processing and nutritional value to animals and humans. The Groundnut Crop provides a solid reference on this most important crop and should be of great use to all those involved with its cultivation and production, including agronomists, plant scientists, food scientists and technologists. As well as being a practical reference source which scientists will want to have to hand, this book should also find a place in all libraries of universities, research establishments and companies with a concern in the crop.

R4,783 Discovery Miles 47 830 Ships in 18 - 22 working days

This book presents a comprehensive overview and analysis of mangrove ecological processes, structure, and function at the local, biogeographic, and global scales and how these properties interact to provide key ecosystem services to society. The analysis is based on an international collaborative effort that focuses on regions and countries holding the largest mangrove resources and encompasses the major biogeographic and socio-economic settings of mangrove distribution. Given the economic and ecological importance of mangrove wetlands at the global scale, the chapters aim to integrate ecological and socio-economic perspectives on mangrove function and management using a system-level hierarchical analysis framework. The book explores the nexus between mangrove ecology and the capacity for ecosystem services, with an emphasis on thresholds, multiple stressors, and local conditions that determine this capacity. The interdisciplinary approach and illustrative study cases included in the book will provide valuable resources in data, information, and knowledge about the current status of one of the most productive coastal ecosystem in the world.
