Forestry Economics introduces students and practitioners to all aspects of the management and economics of forestry. The book adopts the approach of managerial economics textbooks and applies this to the unique processes and problems faced by managers of forests. While most forestry economics books are written by economists for future economists, what many future forest and natural resource managers need is to understand what economic information is and how to use it to make better business and management decisions. John E. Wagner draws on his twenty years of experience teaching and working in the field of forest resource economics to present students with an accessible understanding of the unique production processes and problems faced by forest and other natural resource managers. There are three unique features of this book: The first is its organization. The material is organized around two common economic models used in forest and natural resources management decision making. The second is the use of case studies from various disciplines: Outdoor and Commercial Recreation, Wood Products Engineering, Forest Products, and Forestry. The purpose of these case studies is to provide students with applications of the concepts being discussed within the text. The third is revisiting the question of how to use economic information to make better business decisions at the end of each chapter. This ties each chapter to the preceding ones and reinforces the hypothesis that a solid working knowledge of these economic models and the information they contain are necessary for making better business decisions. This textbook is an invaluable source of clear and accessible information on forestry economics and management for not only economics students, but for students of other disciplines and those already working in forestry and natural resources.
'This book provides an excellent overview of more than a decade of transformation in a forest landscape where the interests of local people, extractive industries and globally important biodiversity are in conflict. The studies assembled here teach us that plans and strategies are fine but, in the real world of the forest frontier, conservation must be based upon negotiation, social learning and an ability to muddle through.' Jeffrey Sayer, senior scientific adviser, Forest Conservation Programme IUCN - International Union for of Nature The devolution of control over the world's forests from national or state and provincial level governments to local control is an ongoing global trend that deeply affects all aspects of forest management, conservation of biodiversity, control over resources, wealth distribution and livelihoods. This powerful new book from leading experts provides an in-depth account of how trends towards increased local governance are shifting control over natural resource management from the state to local societies, and the implications of this control for social justice and the environment. The book is based on ten years of work by a team of researchers in Malinau, Indonesian Borneo, one of the world's richest forest areas. The first part of the book sets the larger context of decentralization's impact on power struggles between the state and society. The authors then cover in detail how the devolution process has occurred in Malinau, the policy context, struggles and conflicts and how Malinau has organized itself. The third part of the book looks at the broader issues of property relations, conflict, local governance and political participation associated with decentralization in Malinau. Importantly, it draws out the salient points for other international contexts including the important determination that 'local political alliances', especially among ethnic minorities, are taking on greater prominence and creating new opportunities to influence forest policy in the world's richest forests from the ground up. This is top-level research for academics and professionals working on forestry, natural resource management, policy and resource economics worldwide. Published with CIFOR
Timber's strength, light weight, and energy-absorbing properties furnish features desirable for bridge construction. Timber is capable of supporting short-term overloads without adverse effects. Contrary to popular belief, large wood members provide good fire resistance qualities that meet or exceed those of other materials in severe fire exposures. From an economic standpoint, wood is competitive with other materials on a first-cost basis and shows advantages when life cycle costs are compared. Timber bridges can be constructed in virtually any weather conditions, without detriment to the material. Wood is not damaged by continuous freezing and thawing and resists harmful effects of de-icing agents, which cause deterioration in other bridge materials. Timber bridges do not require special equipment for installation and can normally be constructed without highly skilled labor. They also present a natural and aesthetically pleasing appearance, particularly in natural surroundings. The misconception that wood provides a short service life has plagued timber as a construction material. Although wood is susceptible to decay or insect attack under specific conditions, it is inherently a very durable material when protected from moisture. Many covered bridges built during the 19th century have lasted over 100 years because they were protected from direct exposure to the elements. In modem applications, it is seldom practical or economical to cover bridges; however, the use of wood preservatives has extended the life of wood used in exposed bridge applications. Using modem application techniques and preservative chemicals, wood can now be effectively protected from deterioration for periods of 50 years or longer. In addition, wood treated with preservatives requires little maintenance and no painting. Another misconception about wood as a bridge material is that its use is limited to minor structures of no appreciable size. This belief is probably based on the fact that trees for commercial timber are limited in size and are normally harvested before they reach maximum size. Although tree diameter limits the size of sawn lumber, the advent of glued-laminated timber (glulam) some 40 years ago provided designers with several compensating alternatives. Glulam, which is the most widely used modem timber bridge material, is manufactured by bonding sawn lumber laminations together with waterproof structural adhesives. Thus, glulam members are virtually unlimited in depth, width, and length and can be manufactured in a wide range of shapes. Glulam provides higher design strengths than sawn lumber and provides better utilization of the available timber resource by permitting the manufacture of large wood structural elements from smaller lumber sizes. Technological advances in laminating over the past four decades have further increased the suitability and performance of wood for modern highway bridge applications.
"Southern forests provide innumerable benefits. Forest scientists, managers, owners, and users have in common the desire to improve the condition of these forests and the ecosystems they support. A first step is to understand the contributions science has made and continues to make to the care and management of forests. This book represents a celebration of past accomplishments, summarizes the current state of knowledge, and creates a vision for the future of southern forestry research and management. Chapters are organized into seven sections: "Looking Back," "Productivity," "Forest Health," "Water and Soils," "Socioeconomic," "Biodiversity," and "Climate Change." Each section is preceded by a brief introductory chapter. Authors were encouraged to focus on the most important aspects of their topics; citations are included to guide readers to further information."
