Download or read book Growing Plantation Forests written by P. W. West and published by Springer Science & Business Media. This book was released on 2013-10-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the scientific principles that are used throughout the world to ensure the rapid, healthy growth of forest plantations. As the population of the world increases so does the amount of wood people use. Large areas of natural forests are being cleared every year and converted to other uses. Almost as large an area of plantation forests is being established annually to replace those lost natural forests. Eventually, plantations will produce a large proportion of the wood used around the world for firewood, building, the manufacture of paper and bioenergy. Forest plantations can also provide various environmental benefits including carbon storage, rehabilitation of degraded land, serving as disposal sites for various forms of industrial or agricultural waste and enhancing biodiversity in regions that have been largely cleared for agriculture. Whatever their motivation, plantation forest growers want their plantations to be healthy and grow rapidly to achieve their purpose as soon as possible. This book discusses how this is done. It is written for a worldwide audience, from forestry professionals and scientists through to small plantation growers, and describes how plantations may be grown responsibly and profitably.
Download or read book Ecosystem Goods and Services from Plantation Forests written by Jürgen Bauhus and published by Earthscan. This book was released on 2010 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Trees Outside Forests written by R. Bellefontaine and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2002 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trees outside forests (including fruit trees, trees in parks, fields, those growing in the wild and as amenities), together with forests and other woodlands, contribute to the structure of the landscape, generate numerous environmental and social services, and yield important food, drink and fuel products as well as meeting other domestic needs of urban and rural populations. However, trees outside forests are not well documented and receive little attention in the formulation of national forestry policy and planning. This publication seeks to fill this gap, by providing information on the role of these resources and options for their integration in territorial management policies.
Download or read book Forest Management and Conservation Agriculture written by Paul Borsy and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines in great detail the design and implementation of a rural development project for smallholder farmers in Paraguay. Over a period of seven years, from 2003 to 2010, the project applied the basic concepts of conservation agriculture, forestry and agroforestry bene?ting 17 thousand farm families in the Eastern Province of the country. The practices promoted closely paralleled those being recommended for sustainable crop production intensi?cation by FAO which seek to enhance agricultural productivity while protecting the natural environment and improving ecosystem services. The book gives a clear-eyed analysis of the lessons learned and the factors for success and failure and so is an invaluable resource for those contemplating similar projects in the future.

This book was released on 2020-07-22 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochar is a carbon-rich material produced from the pyrolysis of organic materials from agricultural and forestry biomass at a relatively low temperature in the absence of oxygen. As such, it has potential for solving many agricultural and environmental problems.This book is divided into five sections: “Introduction,” “Production and Legislation of Biochar,” “Applications of Biochar for Soil Fertility Improvement,” “Role of Biochar for Soil Remediation and Ameliorating Salinity Effects” and “Applications of Biochar for Water Treatment.” Chapters address topics such as the pros and cons of biochar, its production, and its role in remediating and treating contaminated soils and water.
Download or read book Phylogenetic Relationships and Morphology of Cytospora Species and Related Teleomorphs Ascomycota Diaporthales Valsaceae from Eucalyptus written by Pedro W. Crous and published by . This book was released on 2005 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cytospora species and their Valsa teleomorphs are commonly found on Eucalyptus trees and some of these have been associated with stem canker diseases. The taxonomy of these fungi has been confused and has in many cases hindered pathology studies. This study was based on extensive collections of Cytospora species and their teleomorphs from Eucalyptus trees in Africa, Australia, Central and South America, Southeast Asia and California. Sixty-two Cytospora and three Cytospora-like isolates from Eucalyptus, yielding 33 unique ITS-rDNA sequences, were compared for homology to Cytospora species from other hosts. Phylogenetic analysis clustered isolates of Cytospora from Eucalyptus into at least 15 unrelated groups. The Cytospora-like isolates that morphologically resembled Cytospora clustered in a separate group, which is related to Phomopsis. Morphology of the fungi was examined on natural subtrates and in culture in order to identify distinctive characters linked to the phylogenetic lineages emerging from DNA sequence analyses. The specimens from Eucalyptus included morphological features encompassing the Cytospora infrageneric sections Cytospora, Lamyella, Leucocytospora, and Torsellia with the majority residing in sect. Lamyella. Several species exhibited morphological characteristics of more than one section and other species had unique characteristics not represented in the established sections. Phylogenetic inference did not support the sections that have been established based on morphological characteristics. The concepts underlying the establishment of sections in Valsa and Cytospora were, therefore, discarded and descriptive terms have been introduced to distinguish between ascostroma and locule forms. Descriptions of Cytospora australiae, C. eucalyptina, C. eucalypticola, and the anamorphs of Valsa eucalypti and Leucostoma sequoiae have been emended based on morphological studies of cross-sections of holotype and isotype specimens. Teleomorphs associated with Cytospora specimens on Eucalyptus have been described from Australia, California, Chile, Congo, Hawaii, India and Uganda. Each teleomorph had unique morphological characteristics and DNA sequence but several conformed to the broad description of Valsa ceratosperma, even though they resided in separate phylogenetic lineages. Additionally, sequences for V. ceratosperma on hosts other than Eucalyptus resided in separate lineages and were different from all of the isolates from Eucalyptus. One of the lineages, commonly found on Quercus, was recognised as corresponding to the original species concept and was designated as V. ceratosperma sensu stricto (= V. ceratophora). Results of this study have shown that numerous genetically distinct lineages of Cytospora and Cytospora-like fungi occur on Eucalyptus, and that the current description of V. ceratosperma encompases several distinctly different fungi. Leucostoma sequoiae and V. eugeniae were found on Eucalyptus, and V. eucalypti and L. sequoiae have been synonymised. Cultural characteristics including colony colour, pycnidium structure, cardinal temperatures for growth, and tolerance to cycloheximide have been described for the species. Several new species of Valsa and Cytospora from Eucalyptus have also been delimited based on morphological characteristics. This wide-ranging study should contribute to a better understanding of the taxonomy of Cytospora spp. and their teleomoprhs, particularly on Eucalyptus. It is also hoped that this will lead to improved management strategies for diseases associated with these fungi.
Download or read book The Borderlands of Southeast Asia written by James Clad and published by NDU Press. This book was released on 2011 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an academic field in its own right, the topic of border studies is experiencing a revival in university geography courses as well as in wider political commentary. Until recently, border studies in contemporary Southeast Asia appeared as an afterthought at best to the politics of interstate rivalry and national consolidation. The maps set out all agreed postcolonial lines. Meanwhile, the physical demarcation of these boundaries lagged. Large slices of territory, on land and at sea, eluded definition or delineation. That comforting ambiguity has disappeared. Both evolving technologies and price levels enable rapid resource extraction in places, and in volumes, once scarcely imaginable. The beginning of the 21st century's second decade is witnessing an intensifying diplomacy, both state-to-state and commercial, over offshore petroleum. In particular, the South China Sea has moved from being a rather arcane area of conflict studies to the status of a bellwether issue. Along with other contested areas in the western Pacific and south Asia, the problem increasingly defines China's regional relationships in Asia, and with powers outside the region, especially the United States. Yet intraregional territorial differences also hobble multilateral diplomacy to counter Chinese claims, and daily management of borders remains burdened by a lot of retrospective baggage. The contributors to this book emphasize this mix of heritage and history as the primary leitmotif for contemporary border rivalries and dynamics. Whether the region's 11 states want it or not, their bordered identity is falling into ever sharper definition, if only because of pressure from extraregional states. This book aims to provide new ways of looking at the reality and illusion of bordered Southeast Asia.
Download or read book Diseases of Tropical Acacias Proceedings of an International Workshop Held at Subanjeriji South Sumatra 28 April 3 May 1996 written by Kenneth Malcolm Old and published by CIFOR. This book was released on 1997-01-01 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acacias are of considerable social and industrial importance for tropical reforestation and it is expected that about 2 million hectares will be established in Southeast Asia by the year 2000. The acacia species currently of most interest for plantation forestry in the tropics are indigenous to northern Australia, Papua New Guinea and Irian Jaya. Recent reports from Malaysia, Indonesia, Thailand and northern Australia suggest that the future productivity of acacia plantations may be affected by fungal pathogens including leaf spots, shoot blights, stem cankers, heart rot, root rots and gall rusts. During 1995-96 a series of disease surveys was undertaken by forest pathologists in native stands, trials, and operational and social forestry plantings of tropical acacias in Australia, India, Indonesia, Malaysia and Thailand to assess the potential of fungal pathogens as limiting factors to tree growth and productivity and to assess the relative importance of individual fungal pathogens. Tree species included in the surveys were Acacia mangium and A. auriculiformis, on the basis of their current importance as plantation species. A. crassicarpa and A. aulacocarpa were also surveyed as, although they have been planted on a limited scale so far, they are included in provenance and species trials in many locations throughout the region. Scientists who had participated in the project met with research managers of five major Indonesian plantation pulp and paper companies and government business enterprises from 28 April – 3 May 1996 at the base camp of PT Musi Hutan Persada Subanjeriji in southern Sumatra, to present the results of their surveys. This publication is a status report on the diseases of acacias in the several countries based on information presented at the workshop. It provides a benchmark of the current knowledge of the pathology of the four most important Acacia species currently being grown in plantations in tropical areas of Southeast Asia, the Indian subcontinent and northern Australia.
