The Neglect of Governance in Forest Sector Vulnerability Assessments:  Structural-Functionalism and &amp;#8220;Black Box&amp;#8221; Problems in Climate Change Adaptation Planning

Efforts to develop extensive forest-based climate change vulnerability assessments have informed proposed management and policy options intended to promote improved on-the-ground policy outcomes. These assessments are derived from a rich vulnerability literature and are helpful in modeling complex ecosystem interactions, yet their policy relevance and impact has been limited. We argue this is due to structural-functional logic underpinning these assessments in which governance is treated as a procedural &amp;#8220;black box&amp;#8221; and policy-making as an undifferentiated and unproblematic output of a political system responding to input changes and/or system prerequisites. Like an earlier generation of systems or cybernetic thinking about political...

The Management of Fire-Adapted Ecosystems in an Urban Setting: the Case of Table Mountain National Park, South Africa
Provedor de dados: 7

The Table Mountain National Park is a 265-km&amp;#178; conservation area embedded within a city of 3.5 million people. The highly diverse and unique vegetation of the park is both fire prone and fire adapted, and the use of fire forms an integral part of the ecological management of the park. Because fires are both necessary and dangerous, fire management is characterized by uncertainty and conflict. The response of vegetation to fire is reasonably well understood, but the use of fire for conservation purposes remains controversial because of key gaps in understanding. These gaps include whether or not the vegetation is resilient to increases in fire frequency, how to deal with fire-sensitive forests embedded in fire-prone shrublands, and how to integrate...

Learning from Traditional Knowledge of Non-timber Forest Products: Penan Benalui and the Autecology of Aquilaria in Indonesian Borneo
Provedor de dados: 7
Autores: Donovan, D. G.; ;; Puri, R. K.; University of Kent; R.K.Puri@kent.ac.uk.
Traditional knowledge, promoted to make conservation and development more relevant and socially acceptable, is shown to have an important role in identifying critical research needs in tropical ecology. Botanists, foresters, and phytochemists, among others, from many countries have sought for decades to understand the process of resin formation in the genus Aquilaria, a tropical forest tree of South and Southeast Asia. Not every tree develops the resin and, despite extensive scientific research, this process remains poorly understood. Attempts at cultivating the valuable aromatic resin, gaharu, have been uneven at best. Thus, gaharu remains largely a natural forest product, increasingly under threat as the trees are overexploited and forest is cleared. In...

The management of small private forests in the Western World has been under threat owing to rural and agricultural transformations since the Second World War. The actions put in place to preserve those forests are hard to implement because the forests are managed essentially in an unofficial way that is not clearly understood. Through multidisciplinary approaches, our aims were to understand local forest management processes, to assess the continuities and discontinuities of usages and practices in the Coteaux de Gascogne area of France, and to propose guidelines for future forest management. Forest management is shaped by a traditional but unrecognized social system called the house-centered system, which has contributed to a high degree of domesticity...

Interlocking panarchies in multi-use boreal forests in Sweden
Provedor de dados: 7
This paper uses northern Sweden as a case study of a multi-use social-ecological system, in which forestry and reindeer husbandry interact as different land use forms in the same area. We aim to describe the timeline of main events that have influenced resource use in northern Sweden, that is, to attempt a historical profiling of the system, and to discuss these trends in the system in terms of adaptive cycles and resilience. The study shows that key political decisions have created strong path dependencies and a situation in which forestry today is characterized by low flexibility and low resilience due to the highly optimized harvesting of tree resources. Since forestry is the overwhelmingly strongest actor, trends in forestry from the mid-19th century...

We review characteristics of birds in boreal forests in the context of their ecological sustainability under both natural and anthropogenic disturbances. We identify the underlying ecological factors associated with boreal bird populations and their variability, review the interactions between boreal bird populations and disturbance, and describe some tools on how boreal bird populations may be conserved in the future. The boreal system has historically been an area with extensive disturbance such as fire, insect outbreaks, and wind. In addition, the boreal system is vulnerable to global climate change as well as increasing pressure on forest and water resources. Current knowledge indicates that birds play an important role in boreal forests, and...

National Parks and Protected Areas and the Role for Employment in Tourism and Forest Sectors: a Swedish Case
Provedor de dados: 7
Autores: Fredman, Peter; ETOUR; Mittuniversitetet; Peter.Fredman@etour.se; Sandell, Klas; Karlstad University; Stockholm University; klas.sandell@kau.se.
The development of national parks and other protected areas has been widely promoted because of its potential for regional development in peripheral and sparsely populated areas. The argument is that the economic and social benefits seen in national parks in the USA and UK will also occur in the Swedish context in the form of an increased tourism-related labor market. Our aim was to analyze the possibility of such a development both in light of the policy visions of positive regional and local development and from the adversary point of view that protection of land is making it more difficult for 15 sparsely populated mountain municipalities in Sweden to prosper. We used a database covering the entire population of the area for 1991 to 2001. Our results...

Leadership is often assumed, intuitively, to be an important driver of sustainable development. To understand how leadership is conceptualized and analyzed in the environmental sciences and to discover what this research says about leadership outcomes, we conducted a review of environmental leadership research over the last 10 years. We found that much of the environmental leadership literature focuses on a few key individuals and desirable leadership competencies. The literature also reports that leadership is one of the most important of a number of factors contributing to effective environmental governance. Only a subset of the literature highlights interacting sources of leadership, disaggregates leadership outcomes, or evaluates leadership processes...

Humans depend on services provided by ecosystems, and how services are affected by climate change is increasingly studied. Few studies, however, address changes likely to affect services from seminatural ecosystems. We analyzed ecosystem goods and services in natural and seminatural systems, specifically how they are expected to change as a result of projected climate change during the 21st century. We selected terrestrial and freshwater systems in northernmost Europe, where climate is anticipated to change more than the global average, and identified likely changes in ecosystem services and their societal consequences. We did this by assembling experts from ecology, social science, and cultural geography in workshops, and we also performed a literature...

Parcelization and forest fragmentation are of concern for ecological, economic, and social reasons. Efforts to keep large, private forests intact may be supported by a decision-making process that incorporates landowners&amp;#8217; objectives and uncertainty. We used structured decision making (SDM) with owners of large, private forests in Macon County, North Carolina. Macon County has little land use regulation and a history of discordant, ineffective attempts to address land use and development. We worked with landowners to define their objectives, identify decision options for forest management, build a Bayesian decision network to predict the outcomes of decisions, and determine the optimal and least-desirable decision options. The optimal forest...

A Multisector Framework for Assessing Community-Based Forest Management: Lessons from Madagascar
Provedor de dados: 7
Autores: Raik, Daniela B; Cornell University; dbr23@cornell.edu; Decker, Daniel J; Cornell University; djd6@cornell.edu.
Community-based forest management has proliferated throughout Africa as national governments have decentralized the administration of public forestry.  Community-based forestry has taken multiple forms, depending on the assortment of land-tenure systems, forest-use norms, wood demand, and social organization, among others factors. Nature, Wealth, and Power is an analytical framework that has been developed from experiences in natural resource management in Africa. In this paper, we amend the framework to People, Nature, Wealth, and Power (PNWP), and propose it as an analytical lens for community-based forest management initiatives.  We use the PNWP framework to assess the responsiveness of contractual forest management in the Menabe region of Madagascar to...

Mountain ecosystems provide a broad range of ecosystem services (ES). Trade-offs between different ES are an important aspect in the assessment of future sustainable land-use. Management of ES in mountain regions must confront the challenges of spatial and temporal heterogeneity, and interaction with structural changes in agriculture and forestry. Using a social-ecological modeling framework, we assess the relationships between forest and agricultural ES in a mountain region in Switzerland. Based on the concept of jointness in production, we evaluated trade-offs and synergies among food provision, biodiversity conservation, carbon sequestration, and protection against natural hazards. Results show that increasing the provision of a focal ES in a mountain...

A avaliação realizada constatou impactos nas águas fluviais decorrentes da mudança da cobertura florestal original. As pastagens ocasionaram aumento nas concentrações de íons maiores, carbono dissolvido e sedimentos, enquanto a agricultura, e em menor escala a silvicultura, promoveram aumento de nutrientes como o nitrogênio.

Provedor de dados: 20
Autores: Nasi, R.
With a very high forest cover (over 80%) and low population density (below 5 inhbts/km2), Gabon is still a forest biodiversity rich country. Gabon's forests are amongst the richest in Africa in terms of botanical diversity and endemism for example, 22% of plants described in the Flora of Gabon are endemic and the forests of Gabon have more plant species (estimated at 8000 species) than all of the forests of West Africa combined. The fauna is also rich, estimated at more than 190 mammal species, including at least 20 species of monkeys, more than 600 species of birds, 70 species of reptiles and 100 species of amphibians. About 35,000 gorillas and 64,000 chimpanzees dwell in Gabon forests and elephants number between 60,000 and 74,000 individuals. The...

Coastal Ecosystems
Provedor de dados: 20
The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango...

Regeneration Status of Mangrove Forests in Mida Creek, Kenya: A Compromised or Secured Future?
Provedor de dados: 20
Autores: Dahdouh-Guebas, F.; Kairo, J.G.; Gwada, P.
The structure and regeneration patterns of Mida Creek mangrove vegetation were studied along belt transects at 2 forest sites of Mida Creek (3°20'S, 40°00'E): Uyombo and Kirepwe. Based on the species importance values, the dominant mangrove tree species in Mida were Ceriops tagal (Perr.) C. B. Robinson and Rhizophora mucronata Lamk. Tree density varied from 1197 trees ha–1 at Kirepwe to 1585 trees ha–1 at Uyombo and mean tree height was higher at the former site compared to the latter. The sizeclass structure at both localities of Mida showed the presence of more small trees than large ones. Spatial distribution pattern of adults and juveniles varied greatly between sites and they showed a close to uniform pattern (Morisita’s Index I0 &lt;&lt; 1) for...

Forestry resources in Tanzania's wetlands:concepts and potentials
Provedor de dados: 20
Autores: Nshubemuki, L.
Forestry resources include land occupied by, or proclaimed to be forest; the produce found insuch land; and human resources capable of fostering the development of such resources. The following landscape units constitute Tanzania's wetlands: estuaries, open coasts, wetlands incoastal forests, floodplains, freshwater marshes, lakes, peatlands, swamp forests, and ground water forests. Wetlands are sources of food and forest produce, contain plants potentially suitable for agro-forestry and phyto-reclamation, reduce beach erosion, and arc sources of genetic material.Most wetlands face intensive utilisation pressure which endangers their continued existence. Given the multi-utility of wetlands and their diversity in structure, it is not possible to adopt...

Sampling frequency to estimate cumulative nitrous oxide emissions from the soil
Provedor de dados: 86
Autores: Nascimento,Alexandre Ferreira do; Rodrigues,Renato de Aragão Ribeiro.
Abstract: The objective of this work was to assess the influence of gas sampling frequency on the cumulative emissions of nitrous oxide (N2O) from the soil. Gas emissions were assessed over a period of two years (2014-2016), in four systems: eucalyptus forestry, crops, pasture, and native forest. The cumulative emissions of N2O were calculated at sampling intervals of 7, 14, and 21 days. The sampling intervals did not influence the final results of cumulative N2O emissions from the soil in the assessed systems.

Afforestation and Timber Management Compliance Strategies in Climate Policy. A Computable General Equilibrium Analysis
Provedor de dados: 31
Autores: Michetti,   Melania; Nunes Rosa,   Renato.
This paper analyzes the role of afforestation-reforestation and timber management activities, and their major and secondary economic effects in stabilizing climate during the first commitment period of the Kyoto Protocol. In particular, with a Computable General Equilibrium framework, the ICES model, it is inferred how forest carbon sequestration fits within the European domestic portfolio of a 2020-20 and 2020-30 climate stabilization policy. Afforestation and land use are accounted for by introducing their effects in the model. This is done by relying on carbon sequestration curves provided by Sohngen (2005), which describe the average annual cost of sequestration for selected world regions. Results show that afforestation and timber management could...

Modeling Carbon Leakages with Forestation Policies

Autores: de Gorter,   Harry; Drabik,   Dusan; Just,   David R.
This paper analyzes carbon leakage due to reduced emissions from deforestation (RED). We find that leakage with RED is good because the policy induces afforestation that contributes to a further carbon sequestration. By ignoring the domestic component of carbon leakage, the literature can either overestimate or underestimate leakage, depending on the magnitudes of the numerator and the denominator of the leakage formulas. Unlike the literature, we include the land and agricultural markets in the analysis of carbon leakage with forestation policies. In this model, carbon leakage depends on: (1) supply and demand elasticities of timber production and consumption, respectively in the country introducing a RED policy (Home country) and in the rest of the...

Biotechnology's Potential Contribution to Global Wood Supply and Forest Conservation
Provedor de dados: 31
Autores: Sedjo,   Roger A.
Over the past 30 years, industrial plantation forests have become a major supplier of industrial wood. There are several reasons for this, including the improved economics of planted forests due to biotechnological innovations, the increases in natural forest wood costs due to increasing inaccessibility, and rising wood costs from natural forests due to new environmental restrictions related to logging. Forestry today is on the threshold of the widespread introduction of biotechnology into its operational practices. In many cases, the biotechnology likely to be introduced is simply an extension of that being utilized in agriculture, such as herbicide-tolerant genes. However, biotechnology in forestry also is developing applications unique to forestry,...

Az erdőgazdálkodás az erdők fenntartásának, művelésének, sokoldalú, tartamos hasznosításának az alapja. A Föld lakosságának gyarapodásával a történelem folyamán együtt növekedett az embernek az erdővel szemben támasztott igénye. Az igények kielégítésekor hamarosan kitűnt, hogy ezek teljesítésének lehetőségei szigorúan behatároltak. Hosszú távon, tartamosan (fenntarthatóan) akkor nyújthatja az erdő a gazdasági, társadalmi élet számára a legtöbbet, ha az adottságainak megfelelően gazdálkodnak. A Föld erdeinek jelenlegi képe több évezredes fejlődés, valamint emberi beavatkozás eredményeként alakult. A jelenlegi felfogás szerinti „korszerű” erdőgazdálkodás az egyes kontinenseken különböző időben, alig egy-két évszázada jött létre. Abban az esetben azonban, ha...

Practical Issues Concerning Temporary Carbon Credits in the CDM
Provedor de dados: 31
Autores: Dutschke,   Michael; Schlamadinger,   Bernhard.
Afforestation and reforestation (AR) projects in the Clean Development Mechanism are able to create emission permits that can be accounted against the industrialized countries' commitments for limiting their greenhouse gas emissions, as agreed under the Kyoto Protocol. The discussion of how to treat credits from temporary carbon stocks is centering on the proposal for expiring emission credits from AR, which in the subsequent commitment period need to be replaced. While the basic methodological question is thus being solved, the practicalities arising from the solution have so far not been considered. The authors make new proposals on accounting modalities, define the tCER value as compared to a permanent CER, and forecast who will be the potential buyers...

Forest Carbon Sinks: European Union, Japanese, and Canadian Approaches

Autores: Amano,   Masahiro; Sedjo,   Roger A.
This report compares the approaches of the governments of Japan, Canada, and the European Union member countries toward using carbon sinks to meet their respective Kyoto Protocol carbon reduction targets. Various policies have been proposed by which governments can sequester carbon by promoting afforestation and reforestation, slowing deforestation, and undertaking forest management activities under Articles 3.3 and 3.4. At this time, carbon emissions reduction programs are still under development, both within individual countries and within the context of the protocol. Although some of the details have been worked out, concrete definitions are often still lacking, especially as regards impermanence of forests, additionality, leakage, and socioeconomic and...

Institutions and Forest Management: A Case Study from Swat, Pakistan
Provedor de dados: 31
Autores: Gideon,   Kruseman; Lorenzo,   Pellegrini.
Deforestation in the North western part of Pakistan is a long standing problem. The Forestry Department, as formal managers of the forest resources, has been undergoing a long reform process aimed at improving its performance. This reform process has not resulted in less deforestation. From the policy perspective this has been leading to stated intentions to further reform the Forestry Department, the question is whether organizational reform is the answer. We think there are more limiting bottlenecks to sustainable forest management in Pakistan. De facto property rights are not as simple as denoted by statutory law. In this article we explore the mechanisms behind the deforestation and try to uncover mechanisms to reverse the process. Although our...

REDD in the Carbon Market: A General Equilibrium Analysis
Provedor de dados: 31
Autores: Bosello,   Francesco; Eboli,   Fabio; Parrado,   Ramiro; Rosa,   Renato.
Deforestation is a major source of CO2 emissions, accounting for around 17% of total annual anthropogenic carbon release. While the cost estimates of reducing deforestation rates vary considerably depending on model assumptions, it is widely accepted that emissions reductions from avoided deforestation consist of a relatively low cost mitigation option. Halting deforestation is therefore not only a major ecological challenge, but also a great opportunity to cost effectively reduce climate change negative impacts. In this paper we analyze the impact of introducing avoided deforestation credits into the European carbon market using a multiregional Computable General Equilibrium model – the ICES model (Inter-temporal Computable Equilibrium System).

Land-Use Change and Carbon Sinks: Econometric Estimation of the Carbon Sequestration Supply Function
Provedor de dados: 31
Autores: Lubowski,   Ruben N.; Plantinga,   Andrew J.; Stavins,   Robert N.
When and if the United States chooses to implement a greenhouse gas reduction program, it will be necessary to decide whether carbon sequestration policies - such as those that promote forestation and discourage deforestation - should be part of the domestic portfolio of compliance activities. We investigate the cost of forest-based carbon sequestration. In contrast with previous approaches, we econometrically examine micro-data on revealed landowner preferences, modeling six major private land uses in a comprehensive analysis of the contiguous United States. The econometric estimates are used to simulate landowner responses to sequestration policies. Key commodity prices are treated as endogenous and a carbon sink model is used to predict changes in...

Sections 7701 et seq.) gives Aphis statutory authority over genetically modified organisms (GMO), in effect assigning to APHIS a related responsibility of determining whether a genetically altered plant, crop, or tree is likely to pose unacceptable risks to the environment. Although APHIS has considerable experience with crop plants, it has only limited experience with trees. Yet the possible benefits of applying genetic engineering to trees are substantial and include industrial wood production and...

This study describes organizational structure, functions, and facilities of forestry cooperatives in the United States. It evaluates their economic performance and explores current problem areas and potentials for future development. Cooperative organization provides woodland owners professional forestry assistance, in terms of forest management, marketing, and educational activities. Some cooperatives consistently provide these services at less than prevailing rates and obtain higher than average stumpage prices on a local basis. In addition, forestry cooperatives have the potential to play a great role in marketing alternative forest products, such as wood for energy. Woodland-owner organizations have a wide range of sizes, business activities, types of...

Provedor de dados: 31
Autores: Michetti,   Melania; Parrado,   Ramiro.
We present a computable general equilibrium model properly modified to analyse the potential role of the European forestry sector within climate mitigation. Improvements on database and modelling frameworks allow accounting for land heterogeneity across and within regions and for land transfers between agriculture, grazing, and forestry. The forestry sector has been modified to track carbon mitigation potential from both intensive and extensive forest margins, which have been calibrated according to a forest sectoral model. Two sets of climate policies are simulated. In a first scenario, Europe is assumed to commit unilaterally to reduce CO2 emissions by 20% and 30%, by 2020. In a second scenario, in addition to the emissions quotas, progressively higher...

We develop a dynamic nested optimal control model of carbon sequestration associated with the decision to afforest a tract of land given there are uncertainties associated with fire and insect/disease hazards.  Conceptually, these potential hazards are similar in that their occurrence at any time t is uncertain and landowners can take specific actions – although generally different actions - in any time period t to reduce the probability of sustaining losses related to them. The hazards differ, however, in that fire represents a large loss in carbon at a moment in time, while insect/disease infestations are more likely to be reflected in a period...

Australian tree species selection in China
Provedor de dados: 31
Autores: McKenney,   Daniel W.
The Australian Centre for International Agricultural Research (ACIAR), through collaborative projects with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia, and the Chinese Academy of Forestry (CAF), has been involved in tree species selection trials in southern China since 1984. The trials were aimed at identifying fast-growing species of Eucalyptus, Acacia and Casuarina. The Chinese have been planting Australian tree species for more than 100 years, but before the ACIAR project there had been little progress in determining which species and provenances would be best for the local climate and soils. This paper presents an assessment of the economic impact of research undertaken under two ACIAR-supported projects....

A LOGIT ANALYSIS OF PARTICIPATION IN TENNESSEE'S FOREST STEWARDSHIP PROGRAM
Provedor de dados: 31
Autores: Bell,   Caroline D.; Roberts,   Roland K.; English,   Burton C.; Park,   William M.
This study determines the likely effect of cost-share incentives on participation in the Tennessee Forest Stewardship Program and identifies other factors that may contribute to participation.  A random utility model is used to determine the probability that a landowner will choose to participate in the program.  A binary choice model is specified to represent the dichotomous decision and a logit procedure is used to fit the model. Data are obtained from mail surveys of 4,000 randomly selected landowners.  Results indicate that attitudes and knowledge of forestry programs may be more influential in a landowner's decision to participate than monetary incentives.

The Role of Forestry Sinks in the CDM - Analysing the Effects of Policy Decisions on the Carbon Market
Provedor de dados: 31
Autores: Jung,   Martina.
The details on rules and modalities for the inclusion of forestry projects in the Clean Development Mechanism (CDM) are one of the last non resolved implementation issues of the Kyoto Protocol. We examine in detail the implications of different policy decisions concerning the inclusion of CDM forestry sink enhancement projects in the first commitment period of the climate regime (2008-2012). Our analysis is based on the development of marginal forestry cost curves which are implemented into the carbon market model CERT. The latter is a partial equilibrium model of the international market for emissions permits under the Kyoto Protocol. The scenario analysis sheds light on the role of CDM forestry sinks in the climate regime, the effect of different policy...

Forestry in the Next Millennium: Challenges and Opportunities for the USDA Forest Service
Provedor de dados: 31
Autores: Binkley,   Clark S.
Throughout the globe, forestry faces predictable trends associated with the transition from reliance on natural forests to ones created through human stewardship. Laid over the ordinary economics of this transition are increases in the values of the environmental services that forests provide. The three general approaches to forest management--natural forest management, plantation forest management, and preserve management--are evaluated in this economic context. The USDA Forest Service has interesting opportunities to apply each approach, but doing so will require profound organizational changes.

IN PURSUIT OF COMPARABLE CONCEPTS AND DATA ABOUT COLLECTIVE ACTION
Provedor de dados: 31
Autores: Poteete,   Amy; Ostrom,   Elinor.
Research on collective action confronts two major obstacles. First, inconsistency in the conceptualization and operationalization of collective action, the key factors expected to affect collective action, and the outcomes of collective action hampers the accumulation of knowledge. Inconsistent terminology obscures consistent patterns. Second, the scarcity of comparable data thwarts evaluation of the relative importance of the many variables identified in the literature as likely to influence collective action. The International Forestry Resources and Institutions (IFRI) research program addresses both of these problems. Since its founding in 1993, the IFRI network of collaborating research centers has used a common set of methods and concepts to study...

The Survival of a Forest-dependent Species and the Economics of Intensity of Logging: A Note
Provedor de dados: 31
Autores: Tisdell,   Clement A.
Analyses the economics of alternative land-use allocations for a forested area that ensure a targeted viable population of a forest-dependent species, such as the orangutan. The alternative of setting aside a sufficient fully protected portion of the forested area allowing the rest to be used for intensive forestry (or another intensive land use) in which the focal species is unable to survive is compared with that of fully protecting none of the forested area but allowing a sufficient portion of it to be lightly logged to ensure the survival of the targeted population of the focal species with the remainder of the land area (if any) being available for intensive use. The conditions for determining the least cost option (the one that minimizes profit...

The Economic and Environmental Effects of an EU Ban on Illegal Logging Imports. Insights from a CGE Assessment
Provedor de dados: 31
Autores: Bosello,   Francesco; Parrado,   Ramiro; Rosa,   Renato.
Illegal logging is widely recognized as a major economic problem and one of the causes of environmental degradation. Increasing awareness of its negative effects has fostered a wide range of proposals to combat it by major international conservation groups and political organizations. Following the 2008 US legislation which prohibits the import of illegally harvested wood and wood products, the European Union (EU) is now discussing a legislation proposal which would ban illegal timber from the EU market. In this study we use the ICES computable general equilibrium model to estimate the reallocation of global demand and timber imports following the pending EU legislation. With this exercise our final objective is to assess the economic impacts and measure...

Water-resource and land-use issues
Provedor de dados: 31
Autores: Calder,   Ian R.
This paper reviews perceived notions of the relationships between catchment land use and hydrology and explores whether much of the widely disseminated folklore, so often inextricably linked with issues of land use, is based on myth or reality. Gaps in our knowledge of the underlying processes in relation to land use and hydrology are identified. Our ability to apply this knowledge at different scales ranging from the plot to the catchment and regional scales are discussed and specific examples are drawn from Indian and African case studies. Methods for linking spatially distributed land-use hydrological models with economics and ecology through decision support systems are outlined and proposed as a framework for the integrated management of land and...

Autores: Michetti,   Melania; Parrado,   Ramiro.
We present a computable general equilibrium model properly modified to analyse the potential role of the European forestry sector within climate mitigation. Improvements on database and modelling frameworks allow accounting for land heterogeneity across and within regions and for land transfers between agriculture, grazing, and forestry. The forestry sector has been modified to track carbon mitigation potential from both intensive and extensive forest margins, which have been calibrated according to a forest sectoral model. Two sets of climate policies are simulated. In a first scenario, Europe is assumed to commit unilaterally to reduce CO2 emissions of 20% and 30%, by 2020. In a second scenario, in addition to the emissions quotas, progressively higher...

Analyzes the economics of alternative allocations of forested land for uses (dominant-use vs. multiple use) to ensure the survival of a viable population of a forest-dependent species, e.g. the orangutan. The alternatives are (1) setting aside a sufficient fully protected portion of the forest and allowing the rest to be used for intensive logging and (2) fully protecting none of the forested area but allowing a sufficient portion of it to be lightly (selectively) logged to ensure the survival of the population of the focal species with the remaining land (if any) being available for intensive use.

Spatio-Temporal Modeling of Wildfire Risks in the U.S. Forest Sector
Provedor de dados: 31
Autores: Chen,   Xuan; Goodwin,   Barry K.
In the US forestry industry, wildfire has always been one of the leading causes of damage. This topic is of growing interest as wildfire has caused huge losses for landowners, residents and governments in recent years. While individual wildfire behavior is well studied (e.g. Butry 2009; Holmes 2010), a lot of new literature on broadscale wildfire risks (e.g. by county) is emerging (e.g. Butry et al. 2001; Prestemon et al. 2002). The papers of the latter category have provided useful suggestions for government wildfire management and policies. Although wildfire insurance for real estate owners is popular, the possibility to develop a forestry production insurance scheme accounting for wildfire risks has not yet been investigated. The purpose of our paper is...

Two-Part Tax Controls for Forest Density and Rotation Time
Provedor de dados: 31
Autores: Brown,   J. Bradley.
Many forest amenities are derived not only from the age of the trees, but also from the density of the trees.  When an externality such as erosion control is considered, clear-cutting results in much larger damages than occur with selective cutting.  This paper extends current methodology, allowing firms to optimize over both rotation time and the commercial use percentage per acre.  A two-part instrument, a “"clear-cut”" tax combined with a lump sum “"licensing fee"”, controls for commercial use percentage and rotation time in a firm that does not internalize non-timber benefits.  Optimal taxes are presented that correct the firm’'s suboptimal behavior.  A two-part instrument is shown to remedy market failure when a private firm clear-cuts and harvests...

TO 'B' OR NOT TO 'B': AN ANALYSIS OF ALBERTA UNDER THE SOFTWOOD LUMBER AGREEMENT
Provedor de dados: 31
Autores: Ryan,   Chris; Mach,   Helmut.
On October 16th 2006 the Canada-United States Softwood Lumber Agreement (SLA) came into effect. The SLA followed years of trade disputes and litigation initiated by U.S. lumber producers. The SLA ended litigation and dispute procedures by implementing an agreed Canadian export restriction and export tax regime. However, even with a formal agreement in place, points of contention remain on either side. The intent of this study is to evaluate Alberta’s performance under the SLA since its inception in 2006 and the implications for the future. To that end, there are several important characteristics of the SLA that are important to define. The SLA uses a system of export taxes and volume targets to attempt to restrict the total volume of softwood lumber...

Can Permanence Be Insured? Consideration of Some Technical and Practical Issues of Insuring Carbon Credits from Afforestation and Reforestation
Provedor de dados: 31
Autores: Wong,   Jenny L.P.; Dutschke,   Michael.
Greenhouse gas (GHG) removals by afforestation and reforestation project activities under the Kyoto Protocol's Clean Development Mechanism (CDM) are vulnerable to a variety of risks and uncertainties, resulting in the partial or total reversal of such removals. Hence, GHG removals from these sink activities are considered to be of temporary nature and non-permanent. Specific modalities related to non-permanence will need to be developed in order to include afforestation and reforestation project activities under the CDM and for a decision on modalities to be reached at COP 9 in December 2003. Two main options on how to address non-permanence have been proposed, these being temporary credits and insurance of emission reduction credits. This paper discusses...

Forest Service Vision: Or, Does the Forest Service Have a Future?
Provedor de dados: 31
Autores: Sedjo,   Roger A.
This paper maintains that the Forest Service (FS), as an institution, is in deep trouble. It argues that the FS today is an agency without a unique mission and without a supporting constituency. For the FS to be viable in the future it needs a distinct well-defined mission and a committed constituency. The distinct mission needs to be generally supported, or at least not opposed, by most of the American people. The constituency needs to be committed to the FS to the extent that it will provide major support in the Congress for FS budgets. The paper identifies some potential candidates for a mission for the National Forest System (NFS), e.g., as a biological reserve or as a provider of forest recreation. Another potential paradigm could be that of the...

Microbial biomass and activity in litter during the initial development of pure and mixed plantations of Eucalyptus grandis and Acacia mangium
Provedor de dados: 90
Autores: Bini,Daniel; Figueiredo,Aline Fernandes; Silva,Mylenne Cacciolari Pinheiro da; Vasconcellos,Rafael Leandro de Figueiredo; Cardoso,Elke Jurandy Bran Nogueira.
Studies on microbial activity and biomass in forestry plantations often overlook the role of litter, typically focusing instead on soil nutrient contents to explain plant and microorganism development. However, since the litter is a significant source of recycled nutrients that affect nutrient dynamics in the soil, litter composition may be more strongly correlated with forest growth and development than soil nutrient contents. This study aimed to test this hypothesis by examining correlations between soil C, N, and P; litter C, N, P, lignin content, and polyphenol content; and microbial biomass and activity in pure and mixed second-rotation plantations of Eucalyptus grandis and Acacia mangium before and after senescent leaf drop. The numbers of cultivable...

Planning soil tillage using quality function deployment (QFD)
Provedor de dados: 63
Autores: Milan,Marcos; Barros,José Wandmark Duarte; Gava,José Luiz.
The Brazilian forest sector represents about 4% of gross domestic product (GDP) which is correspondent to US$ 21.0 billion. The natural forest area is approximately 4.8 million hectares and for the near future there will be a need to increase the planted area. To avoid or minimize the impact of mechanized practices on forest soils, the reduced tillage has been developed. The aim of this work is to define the technical priorities of the reduced tillage for eucalyptus seedlings, using quality function deployment (QDF). The design requirements classified as the most important to attend seedling demands were the furrow width and depth, and clod sizes. QFD has the potential to be applied to agro-forestry systems to translate plant demands into technical...

ABSTRACT Forest inventory procedures are of utmost importance to studies of wood volume stocks, and forest structure and diversity, which provide relevant information to public policies, management plans and ecological research. The present work focused on the performance of inventory techniques in the Amazon region to evaluate wood volume stocks with higher levels of accuracy while maintaining sampling intensity fixed. Two sampling processes were assessed: simple random sampling and two-stage cluster sampling. The processes were evaluated through the allocation of sampling units with different dimensions, and the effectiveness of the generated estimators was analyzed as a function of stand density and basal area. Simple random sampling resulted in the...

The objective of this work was to elucidate the growth curve of Eucalyptus camaldulensis Dehn. calli analyzing their anatomical modifications. A sigmoid aspect of the growth curve of the calli fresh matter was observed, with five different phases (lag, exponential, linear, deceleration and decline). In the lag phase, the highest growth percentage 87%, was observed, which reduced during the evaluation period to 17% in the linear phase. As for the anatomical analyses, cellular multiplications was observed during the lag and exponential phases and increase in cell size during the linear phase, promoting the calli volume growth and the establishment of the globular conformation.

Water Erosion Prediction Using the Revised Universal Soil Loss Equation (RUSLE) in a GIS Framework, Central Chile
Provedor de dados: 117
Autores: Bonilla,Carlos A; Reyes,José L; Magri,Antoni.
Soil erosion is a growing problem in Central Chile, particularly in coastal dry lands, where it can significantly decrease the productivity of rainfed agriculture and forestry. In this study, the Revised Universal Soil Loss Equation (RUSLE) was integrated into a Geographic Information System (GIS), and used to evaluate the effects of different combinations of vegetative cover on soil erosion rates for Santo Domingo County in Central Chile. Implementing RUSLE in the GIS required a complete description of the county’s soils, climate, topography and current land use/land cover. This information was compiled in rasters of 25 x 25 m cells. RUSLE parameter values were assigned to each cell and annual soil loss estimates were generated on a cell by cell basis....

Differences between urban and rural population with respect to demand on forestry aspects, in a case study of the Turkish province of Bal kesir
Provedor de dados: 65
Autores: Erol,Seçil Yurdakul.
Inhabitants of urban and rural areas are important participants in the process of developing and implementing forest policy. Thus, it is essential to determine their demands and attitudes towards forestry issues. In this context, the demands and evaluation of forest functions are investigated in a case study of the Turkish province of Bal kesir. The findings of the case study show that differences in terms of demands among inhabitants of rural and urban areas are related to forest fires fighting, crimes fighting, forestry-tourism integration, forestation and regeneration activities, and the enlargement of forest areas. The main differences among their assessments of forest functions are related to fire wood production, and the provision of flood and...
