Agroforestry is a land use system that allows for the concurrent production of trees and agricultural crops and/or animals 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. In 1997, CABI published the seminal book on this subject, Temperate Agroforestry Systems, which was a break from the norm as almost all agroforestry texts up to that date were only relevant to tropical areas. The book explored the development of temperate agroforestry and agroforestry systems, concentrating on those areas within temperate zones where the greatest advances, adoptions and modifications had taken place up to that time: North and South America, China, Australia, New Zealand and Europe. This second fully-updated and expanded edition includes additional chapters on India and Chile and, as a result of ongoing advances in the field, separate chapters on the US, Canada, the UK and continental Europe. Today's challenges of climate change, population growth and food security, in concert with the ongoing global requirement for the energy and water needed for a resilient agricultural paradigm, can be met through the wide-scale adoption of agroforestry practices, in both tropical regions and temperate zones. The 2nd edition ofTemperate Agroforestry Systems brings together many examples of temperate agroforestry and will make 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.
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 "

The subject of fruit ripening is one of vital interest and importance to the massive international fruit growing and fruit trade industries. This book is the definitive handbook on the subject, bringing together a vast wealth of important information from an experienced team of international contributors.
The depletion of the tropical rain forests has attracted considerable attention in recent times, and the serious consequences for the global biosphere are widely acknowledged. Yet deforestation continues apace, and in some areas (for example, southeast Asia) the very existence of the forests is seriously threatened. Contrary to popular belief, evidence suggests that local economic and living conditions are more significant in this than timber exploitation for exports to the Northern countries."Tropical Deforestation: A Socio-Economic Approach" offers a new perspective on the economic imperatives which encourage indigenous populations to encroach upon their own forests, and shows how action against deforestation must form part of a wider movement to improve both the living conditions of the local inhabitants and the durability of their national economies.Part One offers an overview of the processes surrounding deforestation, and an assessment of the current situation. Part Two analyses the land-use issues, and explains the socioeconomic imperatives in the affected regions. In an absorbing conclusion. Part Three guides the reader through a series of hypothetical policy scenarios, using a specially adapted economic computer model, to predict which combinations of policies and trade arrangements might bring about a more beneficial state of affairs.

Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters."
Agroforestry reserach and development in Australia has been largely fragmented and many of the research results have never been published and are unknown. The purpose of this volume is to comprehensively review all of the research that has taken place in the field of agroforestry in Australia, including previously unpublished results, providing readers with the latest technical and economic information about using trees in agriculture for the control of salinity and erosion, for shelter and shade, and for the production of timber, fodder and minor forest products. The book provides information concerning planted trees within all of these categories and includes special review of the management of native vegetation on farms. These papers also examine research needs where appropriate. This book stems from the National Australian Conference on 'The Role of Trees in Sustainable Agriculture' which took place in Albury, Victoria, Australia in October, 1991. Each national review paper is based upon a summary of six or more state review research and development papers, prepared specifically for the national conference. The book thus provides readers with a comprehensive overview of agroforestry rsearch in Australia, which is introduced and summarised in the first chapter.
The increasing con'.;ern for the serious problems of forest decline that occurred in the Northern Hemisphere in the late 1970's and early 1980 's led to an emphasis on the necessity of promoting and setting up investigations into the basic physiological mechanisms of forest trees. Since then, the concern about rapid changes has decreased along with the increase of monitored data on European forests health status. But tree physiology has faced new questions about changing climate and increasing atmospheric carbon dioxide concentrations. Advances in plant molecular biology and forest genetics have opened up new avenues in the research on forest tree physiology. At the same, time it has become evident that molecular and genetic tools give only a basis for further research on tree structure and function, which needs basic tree physiology again. On the other hand, the problems of forest decline in Europe are not over. They are no longer discussed daily in the media, but stress is an everyday phenomenon experienced by European forest trees. For instance, in southern Europe and mountainous regions, drought stress and many other abiotic or biotic factors are stressors and cause problems to forests with many important social and protective functions. Stress physiology is a branch of everyday physiology in traditional forestry. How to grow a forest with maximal carbon binding functions and optimal wood quality and rich in biodiversity."
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.
Nouragues is a tropical forest research station in French Guiana. It was established in 1986 for research on natural mechanisms of forest regeneration. Since then a lot of research has been done on this and related topics. This book provides an overview of the main research results, and focuses on plant communities, vertebrate communities and evolutionary ecology, frugivory and seed dispersal, and forest dynamics and recruitment. The appendices give (annoted) checklists of plants, birds, mammals, herpetofauna and fishes found in the same area.
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.
This open access book will provide an introduction to forest entomology, the principles and techniques of forest insect pest management, the different forest insect guilds/feeding groups, and relevant forest insect pest management case studies. In addition to covering 30% of the earth, forest ecosystems provide numerous timber and non-timber products that affect our daily lives and recreational opportunities, habitat for diverse animal communities, watershed protection, play critical roles in the water cycle, and mitigate soil erosion and global warming. In addition to being the most abundant organisms in forest ecosystems, insects perform numerous functions in forests, many of which are beneficial and critical to forest health. Conversely, some insects damage and/or kill trees and reduce the capacity of forests to provide desired ecosystem services. The target audience of this book is upper-level undergraduate and graduate students and professionals interested in forest health and entomology.
Since 1993 a major research programme, "Stochastic Decision Analysis in Forest Management" has been running at Department of Economics and Natural Resources, The Royal Veterinary and Agricultural University (KVL), Copenhagen, in collaboration with Institute of Mathematical Statistics, University of Copenhagen (KU). The research is funded by the two Universities; The Danish Agricultural and Veterinary Research Council; The Danish Research Academy; The National Forest and Nature Agency; and Danish Informatics Network in the Agricultural Sciepces (DINA). A first international workshop in the research programme was held 5 - 8 August, 1996 at Eldrupgaard, Denmark, within the frameworkofacollaborationagreementbetween University of California at Berkeley (UCB) and the Danish Universities, and funded by The Danish Research Academy and the L0venholm Foundation. Having participated in the workshop, Professor Peter Berck (UCB) suggested that the papers be published along with selected papers in the same scientific field, i.e. mainly cointegration analysis of time series in forestry. The editors express their sincere appreciations to the many persons who have contributed to the realisation of the present book: participants in the research programme and the workshop, in particular Professors S0ren Johansen (KU) and Peter Berck (UCB); authors outside the programme/workshop; reviewers of the papers not previously published, in particuler Associate Professors Niels Haldrup (Aarhus University) and Henrik Hansen (KVL); and finally Mrs Mette Riis and Lizzie Rohde who did the tedious work of giving the papers a uniform style. Copenhagen, October 1998.

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.
Rethinking Wilderness and the Wild: Conflict, Conservation and Co-existence examines the complexities surrounding the concept of wilderness. Contemporary wilderness scholarship has tended to fall into two categories: the so-called 'fortress conservation' and 'co-existence' schools of thought. This book, contending that this polarisation has led to a silencing and concealment of alternative perspectives and lines of enquiry, extends beyond these confines and in particular steers away from the dilemmas of paradise or paradox in order to advance an intellectual and policy agenda of plurality and diversity rather than of prescription and definition. Drawing on case studies from Australia, Aoteoroa/New Zealand, the United States and Iceland, and explorations of embodied experience, creative practice, philosophy, and First Nations land management approaches, the assembled chapters examine wilderness ideals, conflicts and human-nature dualities afresh, and examine co-existence and conservation in the Anthropocene in diverse ontological and multidisciplinary ways. By demonstrating a strong commitment to respecting the knowledge and perspectives of Indigenous peoples, this work delivers a more nuanced, ethical and decolonising approach to issues arising from relationships with wilderness. Such a collection is immediately appropriate given the political challenges and social complexities of our time, and the mounting threats to life across the globe. The abiding and uniting logic of the book is to offer a unique and innovative contribution to engender transformations of wilderness scholarship, activism and conservation policy. This text refutes the inherent privileging and exclusionary tactics of dominant modes of enquiry that too often serve to silence non-human and contrary positions. It reveals a multi-faceted and contingent wilderness alive with agency, diversity and possibility. This book will be of great interest to students and scholars of conservation, environmental and natural resource management, Indigenous studies and environmental policy and planning. It will also be of interest to practitioners, policymakers and NGOs involved in conservation, protected environments and environmental governance.
Tree farm business management for small private landowners (those who own about 40 to 4,000 acres). This practical guide to making money in small-scale forestry is written by the major seller of open market timber in the South, who is also publisher of a quarterly newsletter which is the most widely read publication in the business. In this new edition of Tree Farm Business Management, forester Vardaman covers the basics of the business and discusses costs of management and operations, accounting procedures, tax and legal considerations, selling timber, and the role of the big timber companies. Includes case studies of successful timberland investors.
A valuable working resource for professionals. ..".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
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."
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."
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. |
