海南省森林生态补偿机制的社会经济影响分析

建立森林生态补偿机制能够部分或全都地实现森林生态效益的价值，体现出利益相关者之间的平等性，动员全社会参与森林生态系统的保育，更好地加强森林可持续经营的能力。本研究以海南省为案例，从居民问卷分析和机构调查分析入手，分析生态公益林区的生态环境和社会经济影响，讨论建立海南省生态补偿的管理机制。研究表明，大多数农户对生态补偿机制持赞同态度。从总体上看，生态补偿机制的建立对改善生态环境起到了很大的作用，但是农户得到森林生态补偿较低，难以有效地提高农户的生活水平。通过案例研究发现，林业管理机构和居民面临的共同困难是资金不足，由此带来生态公益林保护与周边地区经济发展之间的矛盾，表现为保护与地区经济收入的冲突，耕地面积减少与剩余劳动力的矛盾。在案例研究结果的基础上，探讨海南省森林生态补偿机制的核心问题，提出了海南省森林生态补偿机制的初步设想，包括科学制定地方性生态补偿标准、构建高效的地方管理机构，提高社区能力建设以及扩展生态补偿多元化融资渠道等。     

Quoting “the Environment”: Touchstones on Earth

Media influence public awareness through agenda setting and framing of news by selecting what is published, how frequently and through what frames. This content analysis compares portrayals of climate change based on political ideology of the media. It examines daily coverage of climate change in Santiago, Chile by the conservative, El Mercurio, newspaper, and the liberal, La Nación. Twenty percent of the 1,628 articles published in 2003, 2005, and 2007 which included the words “cambio climático” (climate change) or “calentamiento global” (global warming) were analyzed for frequency, content, images, and frames. The liberal newspaper published twice as many articles that were twice as long, with four times as many illustrations about climate change. They presented more thematic and diverse frames than the conservative newspaper. Government sources and conflict frames dominated both newspapers, reflecting some similar maturation processes of climate change coverage found in Europe, the United States, and elsewhere.     

Socioeconomic Impact of Forest Eco-compensation Mechanism in Hainan Province of China

The establishment of the forest eco-compensation mechanism could realize the value of the forest ecosystem services partly or thoroughly, stress the equality of the stakeholders, encourage public participation in forest ecosystem tendering, and strengthen the capacity of sustainable management. Taking the Hainan province as an example, this study focuses on the analysis of major socioeconomic and ecological impacts of forest eco-compensation in the Qiongzhong County and Lingshui County, and recommends approaches and practices for the establishment of the eco-compensation mechanism in the Hainan Province. Data were collected from a household questionnaire survey. Altogether 120 households have been interviewed, and Statistical Product and Service Solutions (SPSS) was applied for data analysis. Most of the respondents held a positive attitude toward the forest eco-compensation policy which has contributed to the improvement of environmental quality. However, forest protection has limited the opportunities for the income growth of local communities, who have never got sufficient compensation from either the central or local governments. Insufficient financial support to forest institutions and local communities involved in forest management has led to major conflicts in forest management, such as, the conflict between forest protection and local economic development, and decrease in arable land area and increase in surplus labor force. On the basis of case study results, the core issues of forest eco-compensation mechanism in Hainan province are discussed. Finally, suggestions and recommendations that cover forest eco-compensation standards, management institutions, and community capacity building and diversification of financing channels, have been made for the establishment of forest eco-compensation mechanism in Hainan.     

Global-scale quantitative assessment for biodiversity on forest land use: applying the Global No Net Loss approach

Here we propose a method to quantitatively assess and examine Global No Net Loss (GNNL) of forest biodiversity on a global scale. The method produces a GNNL index of existing forest and enables future predictions of forest loss under different assumptions. The method tests the feasibility of the GNNL index and enables discussion of policy for future global scale sustainable forest management up to 2050. The GNNL index was estimated from an equation including forest areas per country per forest type (primary forest, secondary forest and plantation forest), diversity of forest ecosystem, and species density. Estimates derived from historical data revealed an approximate 7% reduction in GNNL index between 1990 and 2005. Predictions of the GNNL index until 2050 emphasize the importance of regenerating large portions of forests felled for agricultural land (or other uses) with secondary forests.     

The Ecological Jeremiad,the American Myth,and the Vivid Force of Color in Dr. Seuss's The Lorax

This essay explores Dr. Seuss's The Lorax through a combination of contextual, visual and narrative-based criticism. Specifically, rhetorical forms of the jeremiad and myth are examined as adaptations to the medium of children's literature. In addition, the force of illustrated images is discussed, including the rhetorical force of color. The essay begins with a discussion of both Dr. Seuss and The Lorax within the contexts of the early environmental movement's rhetoric of alarm and political activism. It then outlines Seuss's attempt at “propaganda with a plot” arguing that a collision of the American myth and ecological jeremiad parallel and divert from the environmentalist norm. A detailed analysis of illustrated imagery and the function of color demonstrate the rhetorical force toward narration and ideology possible in the visual form.     

Climate Variability and Deforestation—Reforestation Dynamics in the Philippines

Changes in the conditions in the 'warm pool' in the Pacific region are reflected in the changes in the local climate system of the Philippines. Both El Niñno and La Niñna episodes in the Pacific Oceans introduce high variability into the local climate pattern, especially rainfall, in the Philippines. Whereas El Niñno appears when annual rainfall is ≥10% lower than normal annual rainfall, La Niñna occurs when annual rainfall is at least equal to the normal. About 15.7 million ha of forest cover had been lost between 1903 and 1998, but only 1.64 million had been reforested in the same period, indicating the presence of unbelievably low ecological stability. Apart from this, the denuded forests freed about 8.24 × 10⁹ Mg C into the atmospheric greenhouse pools. Neither deforestation nor reforestation was undertaken with deliberate regard to the occurrences of El Niñno or La Niñna. Very high rates of deforestation were observed to coincide with or precede strong El Niñno or Niñna episodes, thus confounding further the ecological instability of denuded forest systems, especially those with slope ≥18%. Similarly, the reforestation cycle indicates that saplings are at most 5 years old every time an El Niñno or a La Niñna occurs; in most reforestation schemes, saplings are only 1–2 years old when these events occur. These reforested areas are vulnerable to drought in El Niñno years and to high runoff erosion during La Niñna years. Because they are young, saplings in reforested areas dry easily and pose hazards to forest fires, which were observed to destroy larger tracts of forest cover during El Niñno more so when annual rain ≥10% below the normal. In retrospect, the study indicated that had forests been exploited with conscious regard to the recurrence of El Niñno or La Niñna episodes, ecological impacts could at least be toned down. In the same vein, reforestation should have been more successful it were implemented with due considerations to extreme climate variability. Once trees were planted, the weather elements become more crucial than politicians' meddling and other socio-economic factors to the growth and development of reforested sites.     

Forest protected area governance in Bangladesh:a focus on the legal and policy framework

In the context of renewed interest in collaboration in natural resource management,the collaborative governance approach has lately been introduced to the forest Protected Areas(PAs)in Bangladesh.The adoption of this co-management approach is seen as an attempt to influence the governance process towards a transformation from the conventional custodian system to a more participatory management regime.Recognition of rights and responsibilities,effective participation,and equitable distribution of benefits amongst the key stakeholders working under a facilitative policy and legal framework are believed to address the broader goals of sustainable development Notwithstanding the resurgence of interest in governance of forest PAs through the co-management approach,academic research on the subject remains limited.This article attempts to review selected key information and milestones on the forest PAs governance with special reference to the major policies and legal documents.With a brief introductory section,this article focuses on the genesis and selected major features of the Forest PAs in the country.The discussion then dwells on the policy and legal framework and provides a critique on its relevance for promoting community participation.The existing institutional arrangements for community engagement in protected area governance are also analyzed in light of the national and international commitment and policy obligations on the part of the country.The salient observations and key findings of the study include the following:(1)despite its limitations,comanagement as concept and practice has gradually taken roots in Bangladesh;(2)the degree and level of active community participation remain low and limited,and there is also clear weakness in conscientizing and orientating the local community on the key legal and policy issues related to PA governance in the country;and(3)policy makers,practitioners,and other local stakeholders related to PA governance need to be oriented on international commitment and national de     

The Flood Myth in the Age of Global Climate Change

When released, The Day After Tomorrow was widely described by critics and the movie's creators as a pro-environmentalist film. This essay argues that The Day After Tomorrow articulates a variation of apocalyptic discourse identified as a flood myth. The authors conclude that this version of the flood myth largely undermines contemporary environmental discourse that attempts to generate public activism in addressing ecological problems, by replacing an emphasis on human efficacy with symbolic vindication and exchanging collective effort for individual survivalism. The film thus serves as a cautionary tale about the potential consequences of contemporary mythic discourse presented as supporting environmental activism.     

Culture,Progress and the Media: The Shad as Synecdoche in Environmental News Coverage

This essay examined the use of synecdoche in newspaper coverage of a dispute over water rights between the Mattaponi Indians and the city of Newport News, Virginia. The Mattaponi used the shad as a rhetorical trope to explain the tribe's relationship to the river and their fears about the reservoir's impact. The reservoir proponents, however, treated the shad as a representation of the conflict surrounding the reservoir, and this construction was reflected in articles that appeared in The Daily Press, a local daily newspaper. This essay argued that, ultimately, the treatment of a single species as a synecdoche in environmental disputes undermined the Mattaponi's position. The media which are instrumental in defining environmental issues for the public, misinterpreted a rhetorical trope that was proffered as a representation for a complex set of values and instead focused attention on the species itself rather than the values that it represented.     

Vietnamese Uplands: Environmental and Socio-Economic Perspective of Forest Land Allocation and Deforestation Process

Vietnam, in the ongoing transition to market economies, has to cope with high rural poverty and a dramatic process of forest loss and environment degradation, particularly in the mountainous regions. The government considers rural poverty as the main cause of environment degradation, associated with slash-and-burn cultivation and to an unclear definition of property rights on forest land. In 1993, the government launched a Forest Land Allocation programme aiming to lease forest lands to individual households and, on this basis, to solve food security problems, halt the increasing environment degradation and preserve the remaining forests.To evaluate the results of this land reform policy, two upland pilot communes have been intensively monitored. The environmental and economic impacts of the forest land reform allocation in the two study areas are presented, after providing a background on the Vietnamese situation of mountain zones. On the basis of these findings, it is discussed as to whether the current forest land allocation process may actually promote local development and natural resources conservation, and under what conditions. Deforestation problems must be tackled also with new macroeconomic policies (e.g. credit programmes to support sustainable agriculture practices) and social policy (e.g. reduction of demographic pressure), together with the reform of the State institutions (e.g. State Forest Enterprises) involved in management of the forest areas.     

Prolepsis and the Environmental Rhetoric of Congressional Politics: Defeating the Climate Stewardship Act of 2003

As a device of argumentative anticipation, prolepsis use generally is considered a positive rhetorical strategy. Turning to the Climate Stewardship Act (CSA) of 2003, this article contributes to our understanding of environmental communication, political argumentation, and rhetorical theory by examining how proleptic miscalculation can actually produce devastating consequences against one's cause when used as a source of invention. Proponents of the CSA relied on creating proleptic arguments grounded in a scientific understanding of climate change to such an extent that they mistakenly downplayed the economic arguments against the Act. This orchestrated miscalculation was encouraged and strengthened by key US senators. This article concludes by discussing contributions to scholarly understanding of prolepsis use in public policymaking and offers practical suggestions for improving communication in future considerations of environmental legislation.     

Forest income and dependency in lowland Bolivia

Forests contribute to livelihoods of rural people throughout the tropics. This paper adds to the emerging body of quantitative knowledge on absolute and relative economic importance, through both cash and subsistence income, of moist forests to households. Qualitative contextual information was collected in six villages in lowland Bolivia, followed by a structured survey of randomly selected households (n = 118) that included four quarterly income surveys. We employed a novel data collection approach that allows detailed estimation of total household accounts, including sources of forest income. We estimated the average forest income share of total annual household income (forest dependency) at 20%, ranging from 18 to 24%. Adding environmental income increased the average to 26%, being fairly constant across income quartiles at 24–28%. Absolute levels of forest income increased with total household income, while forest dependency was the highest in the best-off income quartile—the primary harvesters of forest products are better-off households. The pattern of high forest dependency among better-off households has also been reported from other countries, indicating that this pattern may be more common than advocated by conventional wisdom. Using ordinary least squares (OLS) regressions, we found significant determinants of absolute forest income to be household size, sex of household head and area of cultivated land; the significant determinants for forest dependency were level of education, whether household head was born in village and whether household was food self-sufficient. Better-off households were able to realise cash income from forests, while poorer households—in particular if headed by women—were more reliant on subsistence forest income. We argue that the differential patterns of forest income across income quartiles should be considered in future development interventions and that findings indicate a potential for forests to contribute to moving households out of poverty.

A comparative review for understanding elite interest and climate change policy in China

China’s climate change policy has rapidly evolved from one of neglect to necessity with sinologists drawing on a wide range of theories in trying to explain this shift. The rising influence of citizens' movements coupled with international pressure are often cited as significant drivers behind the government’s evolving climate change strategy. But can the influence of public pressure and international lobbying offer a complete explanation for the government’s dramatic policy changes? In this article, we advance theoretical pluralism where three contending schools of thought are made complementary to offer distinct explanations for understanding the mechanisms and rationale for Beijing’s elite-driven climate change policy. In brief, by bridging three separate theoretical streams including rational choice theory, authoritarian environmentalism and advocacy coalition framework, we show that the interests of elites in China’s upper political echelon are the driving force behind the country’s climate change policy.     

森林资源经济利用的政策模拟模型应用研究

林业政策在对森林资源的培育、保护和利用方面起相当大的作用.在市场机制作用的框架下林业政策的作用更多的是通过影响市场机制传递的产品和生产要素的价格信号,进而影响生产经营主体的收益成本预期及其决策行为,最终影响到对森林资源的培育、保护和利用的效果,因此分析和认清林业政策对林业发展的作用机制和影响效果有重要的意义.本文基于市场机制.以林业经济福利为目标,把森林资源培育的第一产业环节和以森林资源为原料的第二产业发展结合一起作为完整的产业链,构建一个林业的政策模拟模型.利用该模型,对木材价格、林业税费、信贷利率和采伐限额等林业经济政策的影响进行了定量分析,着重比较了林业产权制度改革前后政策变化所产生的效应,以及所具有的激励效果,从而认识林业政策的变动和调整如何影响政策目标,为政策的制定和对合理政策进行选择提供参考的依据.     

Scenarios and story lines: drivers of land use change in southern Mexico

The study presents three scenarios of land use and cover change (LUCC), the most important factor for environmental degradation in southern Mexico. We developed story lines and quantitative projections for regional scenarios based on historic LUCC processes, environmental policies, socioeconomic drivers, stakeholder consultations and official planning documents to gain a better understanding of drivers of LUCC, and quantitative scenarios were modeled with DINAMICA-EGO. Regionally specific interactions between social and natural systems are recognized, and detrimental policies and policy options for landscape conservation and management for sustainability are acknowledged in a base line, variant and alternative scenario. Incongruent policies and ineffective ground implementation of conservation actions were identified as the critical underlying drivers of deforestation and forest degradation that could lead to a severe reduction in natural forests, while the local socioeconomic situation stays precarious. The baseline scenario parts from an analysis of historic LUCC processes and shows the consequences of LUCC tendencies: 73% of temperate forests and 50% of tropical forests would get deforested until 2030. In the variant scenario, these tendencies are adjusted to planning goals extracted from official documents and recent changes in public policies. The alternative scenario further addresses policy options for fostering conservation and sustainable development, but because of the time lag of implementation, still 59% of temperate forests and 36% of tropical forest would get lost until 2030. Nevertheless, this represents a reduction of 13% of forest loss and 11% less pastureland due to the proposed measures of conservation, and sustainable management, including strategies for reforming agricultural systems, agricultural and forestry policies and trade, land tenure and livelihood risk management.     

The Role and Effectiveness of Local Institutions in the Management of Forest Biodiversity in New Dabaga-Ulongambi Forest Reserve,Iringa Region-Tanzania

Abstract

This paper examines the role and effectiveness of local institutions in the management of forest biodiversity in New Dabaga-Ulongambi Forest Reserve, Tanzania. Data were obtained through questionnaires, interviews, focus group discussions, participatory rural appraisal and field observations. The study revealed that the most remarkable local institutions connected to forest biodiversity management include: Village Natural Resources Management Committee (92%), tree nursery group (79.4%), beekeeping groups (61.1%), fish farming (43.3%), livestock rearing group (33.9%). Main activities carried out by local institutions which directly contribute to the sustainability of forest reserve include: forest patrols, fire extinguish, preparation of fire breaks, planting of trees along the forest boundaries, creation of awareness, arresting of forest defaulters, participation in income generation activities. For the purpose of realization that local communities are capable of managing forest biodiversity through their traditional institutions, the policy should provide tangible opportunity for local communities to meet their needs as they manage the forests.     

Places and People: Rhetorical Constructions of “Community” in a Canadian Environmental Risk Assessment

This paper addresses the issue of public engagement in environmental risk contexts through a rhetorical analysis of the key term “community” in a risk assessment of mining-caused soil contamination. Drawing on Burke's concept of terministic screens and method of cluster criticism, the analysis shows the divergent constitutions of “community” in the Sudbury Soils Study's official discourse and the citizen-activist rhetoric of the Community Committee on the Sudbury Soils Study. Tracing the verbal and visual clusters within each organization's articulation of “community” as place and people reveals how the official Study's technical-regulatory ideology of environmental risk and citizen participation is countered by the Community Committee's contestatory environmental justice ideology. These competing views of “community” are mutually constitutive in that the official Study's mainstream risk discourse establishes the terms for the Community Committee's reactive counter-discourse, thus limiting citizen participation mainly to questions of “downstream” impacts. Our rhetorical analysis of “community” suggests a generative method for understanding the complex power relations animating specific risk communication contexts as well as for potentially reinventing “community” in terms more conducive to meaningful citizen engagement.     

Species of the Month: Anti-Whaling,Mediated Visibility,and the News

Paul Watson, founder of the Sea Shepherd Conservation Society and captain of anti-whaling ship the Steve Irwin, has emerged as one of the world's most visible environmental protesters. This essay, based in part on a long interview with Watson in Australia in 2009, analyzes his mediated visibility and thus capacity to participate in public debate by isolating various components of his strategic activities under four themes: mediated protest, symbolic power, media practices, and celebrity. It argues that Watson's visibility involves a complex flow of information and meanings across various “old” and “new” media form, but remains reliant on news media. Thus, despite his generally astute media practices and strategies, Watson's visibility is contingent on a set of professional practices and logics unlikely to provide sustained news access or long-term legitimacy to a political “outsider.”     

Forest fires and adaptation options in Europe

This paper presents a quantitative assessment of adaptation options in the context of forest fires in Europe under projected climate change. A standalone fire model (SFM) based on a state-of-the-art large-scale forest fire modelling algorithm is used to explore fuel removal through prescribed burnings and improved fire suppression as adaptation options. The climate change projections are provided by three climate models reflecting the SRES A2 scenario. The SFM’s modelled burned areas for selected test countries in Europe show satisfying agreement with observed data coming from two different sources (European Forest Fire Information System and Global Fire Emissions Database). Our estimation of the potential increase in burned areas in Europe under “no adaptation” scenario is about 200 % by 2090 (compared with 2000–2008). The application of prescribed burnings has the potential to keep that increase below 50 %. Improvements in fire suppression might reduce this impact even further, e.g. boosting the probability of putting out a fire within a day by 10 % would result in about a 30 % decrease in annual burned areas. By taking more adaptation options into consideration, such as using agricultural fields as fire breaks, behavioural changes, and long-term options, burned areas can be potentially reduced further than projected in our analysis.
