文中介绍气候谈判产生的背景、谈判机制设计、影响谈判进程的因素等方面研究现状, 分析贸易政策与环境、资源禀赋、汇率变动等对木材产品国际贸易的影响; 在此基础上, 讨论气候谈判与木材产品国际贸易之间的关系。现有研究文献表明:气候谈判通过关税直接对木材产品国际贸易产生影响, 通过非关税措施包括森林认证、进口产品检验检疫、森林碳汇等对全球木材产品国际贸易产生直接或间接影响。然而, 这些研究主要还是基于简单的逻辑推理, 对于涉林气候谈判影响木材产品国际贸易的机理并没有进行深入剖析, 更没有通过大样本实证检验涉林气候谈判对木材产品国际贸易的影响。 相似文献

The shortfall of timber resource in China constantly keeps about 150 million m3, which mainly relies on import to fill in the gap. However, Russia, the key timber supply state of China, has encouraged the development of its national intensive timber processing and therefore the Russian Far East Region started to gradually restrict log export. To this end, this paper analyzes the situation of forest industry and timber production in Russian Far East and discusses the current status and existing problems in timber trade between Russian Far East and China. At the end, the paper presents policy recommendation for future timber trade between Russian Far East and China and views their forestry cooperation prospect. 相似文献

我国木质林产品贸易与森林生态安全耦合度研究 总被引:1,自引:0,他引:1
“两头在外”是我国林产品贸易的典型特征, 它意味着对国内和国外森林资源的大量消耗。木质林产品贸易和森林生态安全的协调是开放条件下实现我国森林可持续发展的必经之路。文中运用耦合理论研究1961-2010年我国木质林产品贸易和森林生态安全之间的协调问题, 结论认为:1)2004之前森林生态安全指数高于木质林产品贸易指数, 2005-2008年则低于木质林产品贸易指数, 1991年之后木质林产品贸易指数的波动幅度显著大于森林生态安全指数。2)1961-1999年森林生态安全指数与木质林产品贸易指数的协调状态在初级协调和勉强协调之间波动; 2000年之后二者的协调进入稳定阶段, 并在2003年由初级协调进入中级协调阶段。 相似文献

ABSTRACTAs the role of forests in climate change mitigation is explicitly recognized in the Paris Agreement, the need to enhance the adoption of Sustainable Forest Management (SFM) practices is crucial. Therefore, this paper aims at identifying and evaluating barriers in adopting SFM practices in the context of forest carbon emission reductions. A total of 15 barriers in adopting SFM practices are listed through literature and expert inputs. Using Cameroon as a case study, the listed barriers are then evaluated by experts to determine their relative importance using the Analytical Hierarchy Process (AHP) method. According to our findings, the ‘Regulatory and Legislative frameworks’ barrier category was attributed to the highest importance among other categories, in adopting SFM practices in the forestry sector. ‘Inadequate political will and incentive to enforce regulations’ appears to be the major obstacle in adopting SFM practices in Cameroon. As carbon emission reduction initiatives are being developed, there is need to move from broad to concrete suggestions that will overcome these barriers. However, proper diagnosis is necessary in order to target barriers with the right incentives and enabling conditions that will support carbon programs and projects to deliver effective emission reductions. 相似文献

Forestry and forest ecosystem are highly sensitive to climate change.At present,studies about the responses of forests to climate change in China are more focused on physical influences of climate change.This paper firstly divided the key impact factors of climate change on forest and forestry developing into direct factors and indirect factors,and then made an assessment on climate change affecting future forestry development from the aspect of forest products and ecological services.On this basis,the adap... 相似文献

Fossil fuel consumption in recent decades has caused the rise of CO2 concentration in the atmosphere, with negative consequences on the environment and human health. This study develops a methodological framework to quantify carbon credits from carbon-oriented forest management and evaluates the economic sustainability of their sale. Application of the framework to two forest compartments with long-lasting active management in the Western Italian Alps showed the feasibility of the methodology and provided insights on its replication in other contexts. Particularly, the Carbon-oriented scenario led to a reduction of both the extracted wood volume (10% and 6.5% CASE1 and CASE2, respectively) and Net Present Value (32% and 29%), leading to a carbon credit price of 19.6 € MgCO2eq?1? and 44.1 € MgCO2eq?1 to counteract these losses.
This work allows us to highlight the factors needed to design and evaluate alternative forest management options while considering the consequences of climate change. Moreover, the hypothesized scenarios include an economic remuneration of the positive externalities provided by sustainable forest management.
Finally, the proposed workflow entails undeniable environmental benefits while contrasting climate change but still looks undesirable with respect to the traditional timber-oriented management in compartments where high-quality wood products can be obtained. 相似文献

Protected areas in Nigeria are important ecosystems for carbon storage. The aim of this study was to estimate and map tree aboveground biomass (TAGB) and carbon (TAGC) within a tropical forest in Nigeria. Stepwise regression analysis was implemented to develop models for predicting TAGB in the forest stand, by integrating field TAGB data with Landsat 8 OLI data. Spectral variables used in the analysis include spectral bands, vegetation indices, tasseled cap indices and principal components. Model validation was performed using independent sample plots. The results showed that incorporating more than one category of spectral variables improved the prediction of TAGB. The best-fit model was applied to map the spatial distribution of TAGB and TAGC. The TAGC was estimated as 52.3% of TAGB, based on the average carbon content of tree species derived in this study. Average TAGB and TAGC estimates for the forest stand were 373.1 ± 165.4 t ha?1 and 194 ± 82.7 t ha?1, respectively. Reliable estimates of TAGB and TAGC for the forest reserve were obtained. This study provides important information required to manage the forest stand for optimal carbon sequestration. 相似文献

The structure of Japanese timber markets has changed drastically during recent decades. After the introduction of a large
amount of imported softwood products. Japanese timber producers have faced global competition with foreign timber suppliers
such as Canada, the US, and recently Nordic countries. In this paper, we present a forest sector model for lumber markets
with a focus on eight aggregate regions (Tohoku, Kanto, Hokuriku, Chubu, Kinki, Chugoku, Shikoku, and Kyushu) in Japan. The
proposed model is based on the Samuelson-partial equilibrium formulation, which searches for an optimal solution by maximizing
the net social payoff subject to demand and supply constraints. A nonlinear programming solution technique is incorporated
into the proposed model. Three types of lumber are considered,i.e., domestic lumber, the lumber processed in Japan from imported logs, and imported lumber from the US and Canada. Using data
for 1998, our analysis indicates that the derived equilibrium solution has a higher price for the imported lumber supply in
all regions, and a lower price for the other two products in most regions than the actual current price in 1998. The derived
net social payoff gains 1.6% compared with the one derived with the current set of prices and quantities.

In this article, an engineering approach is used to derive the access cost function for roundwood in northern Sweden. This approach can make use of detailed biological, technological and economic information and can give insights that cannot be gained with statistical methods. The engineering approach gives a reliable estimate of the whole cost function, so it avoids the difficulties of the statistical approaches in discriminating between different functional forms. The computations are based on data from the Swedish Forest Survey. Cost distributions are derived both at the roadside and at the mill and also with and without subsidies to forestry. Some applications to forest policy problems are mentioned. The elasticity of the cost curve near the current price level is the same as previously reported price elasticities. 相似文献

This article examines the current state of community forestry in Laos. The rationale for community forestry in the Lao context is presented, followed by a discussion of the development of the Lao version of community forestry, called participatory sustainable forest management (PSFM). The history of a project supported by an international non-government organization that attempted to implement PSFM and that was subsequently discontinued by the Lao government is then presented, followed by an analysis of the reasons for government opposition to the project. Examples of more successful community forestry systems in two countries—Nepal and Mexico—are contrasted with Laos's state-centered PSFM model. Lessons from these countries suggest that fundamental institutional changes are necessary for community forestry to take hold in Laos. 相似文献
