Agroforestry as a sustainable landuse option in degraded tropical forests: a study from Bangladesh

The tropical deciduous forest in Bangladesh provides a substantial part of country’s forest and where the government has introduced participatory agroforestry landuse. This study examined management issues, financial viability, and environmental as well as social sustainability of this landuse system. The forest department allocated a plot of size 1.0 ha among the selected participants where they were allowed to practice agriculture as well as to plant tree species for 10 years. The financial indicators indicated that the landuse system was profitable and attractive [net present value (NPV) = US$ 17,710 and benefit-cost ratio (BCR) = 4.12]. It was also viable and suitable from the social and environmental stand points. The study concluded that under the present environmental and socio-economic scenario, this production system could be the best management tool that would earn money, stop forest degradation, and finally be a model of sustainable land management in an overpopulated country.     

实现林业可持续发展的财政政策取向

林业的可持续发展，既体现了林业生产力发展水平和生态文明社会，又承载着满足社会日益增长的多样化需求，在人与自然和谐发展以及建设环境友好型社会中居于十分重要地位。分类经营是实现林业可持续发展的重要途径。国家应当制定以公共财政为主全社会多渠道投入支持林业建设的财政政策。     

从政府与农户的动态博弈分析退耕还林工程的可持续性

退耕还林工程的实施取得了一定的成绩，但是也存在一些问题，制约了工程的可持续性。其中一个重要的原因就是补偿问题。通过经济学中的博弈理论构建退耕还林动态模型，从补偿的角度分析了退耕还林工程中存在的问题，并提出工程可持续性建议，即：①对生态林和经济林实行差别补偿；②对不同地区实行差别补偿标准；③延长补偿期限，实行分年度对农户进行不同数量的补偿；④对工程区进行产业结构调整，加强农户技能培训。     

低价林概念商榷

生态系统服务功能已成为生态学及相关领域关注的焦点,人类渴望高效优质的生态系统服务功能。由于种种原因形成了大量的不符合人们经营要求的低价林,它们的生态系统服务功能低下,在很大程度上影响和制约着我国林业乃至社会与经济的可持续发展,低价林问题已引起了人们的普遍关注。目前在学术研究领域和生产实践中,关于低价林方面的称法或概念很多,很不规范,不统一,这也在一定程度上造成了当前低价林的相关研究和实践中较混乱的局面,也严重影响了相关方面的学术交流等活动。针对低价林领域概念比较混乱,不规范,不统一的现状,从森林经营目标的角度定义了低价林概念：把那些由于种种原因引起的没有达到主要经营目标的林分统称为低价林。参照我国林种的划分给出了低价林分类系统;低价林的命名应遵循“（优势）树种－低价－林种”方法。     

论中国林业现状及可持续发展战略

本文对中国林业的现状及其因在林破坏而引发的一系列生态和环境、经济和社会等问题进行了评述，强调指出可持续发展特别是林业可持续发展是解决上述问题的必然选择，并从生态学、经济学、社会学等方面论述了林业可持续发展的目标、准则及对策。     

林业生态安全效率及其影响因素的DEA-Tobit模型分析——基于生态与产业共生关系

林业生态安全的资源投入产出效率及影响因素的研究利于实现林业生态安全建设资源的合理配置,促进林业生态-产业系统的共生发展.运用DEA-SBM模型和Malmquist指数模型对2005～2014年间我国31个省份的林业生态安全效率进行时空分析的基础上,借助PSR模型构建了林业生态安全效率的影响因素体系并利用Tobit模型进行回归分析.结果表明:林业产业发展更依赖于规模的扩张而不是技术水平的提升,这不利于生态安全的可持续发展.林业生态安全效率的动态波动较大且技术进步指数偏低,林业生态与林业产业的协调发展存在较大困难.在林业生态安全效率的影响因素体系中,城市化水平、森林消长比,生态林面积、单位面积森林蓄积,环境保护和生态建设财政支出等对林业生态安全效率的提升作用明显;人均资源总量,科研经费投入强度等对林业生态安全的发展产生较大影响.最后,提出了优化林业产业结构促进林业产业规模集约高效发展、加强创新提升技术效率促进林业生态与产业一体化发展、实现林业资源总量提升和公众生态文化建设的协调发展等对策.     

社会资本测量研究综述

高水平的社会资本是生态、社会与经济职责和谐过程的先决条件,社会资本在可持续发展领域的作用已引起了全社会的广泛关注。社会资本测量作为理解其作用机制的前提与基础,一直是学术界关注的焦点。然而,在实践中,由于缺乏统一的测量工具,对于社会资本结构性成分系统解耦、社会资本在地区间比较、社会资本精确理解等都存在困难。本文从确定社会资本的基本维度出发,分析了社会资本测量中存在的问题,发现当前主要从社会资本的网络、信任及规范三个基本成分、个体与集体两个分析层次出发寻求替代指标对社会资本进行测量,存在测量工具缺乏系统性、替代指标缺乏普适性、分析尺度转换缺乏有效性、社会资本成分与其影响结果的测量混淆等问题。为了更好地理解社会资本及其作用机制,本文提出应从确认社会资本的主要维度开始,建立系统的测量框架、采用多样化的研究方法、选择功能等同的测量工具等入手进行社会资本测量。     

Energy and Sustainable Development at Global Environmental Summits: An Evolving Agenda

This paper presents a framework for understanding energy issues in the context of sustainable development. It posits that there are three important ways in which energy is related to sustainable development: (a) energy as a source of environmental stress, (b) energy as a principal motor of macroeconomic growth and (c) energy as a prerequisite for meeting basic human needs. These three dimensions correspond to the three dimensions of the often-used triangle of sustainable development: environmental, economic, and social. Using this framework, the paper traces how successive environmental summits at Stockholm (1972), Rio de Janeiro (1992) and Johannesburg (2002) have dealt with energy issues. It identifies a slow, surprising and important evolution of how energy issues have been treated at these global discussions. Energy has received increasing prominence at these meetings and become more firmly rooted in the framework of sustainable development. Stockholm was primarily concerned with the environmental dimension, Rio de Janeiro focused on both the environmental and economic dimensions, and the major headway made at Johannesburg was the meaningful addition of the social dimension and the linking of energy issues to the UN's Millennium Development Goals.     

A pattern for partnership between LMDH and Perhutani to enhance local community prosperity and preserve the forest: a case study at RPH Besowo,Kediri Regency,Indonesia

The deforestation in Indonesia is already alarming. One of the strategies used by the government to overcome forest deforestation is social forestry. This program is called PHBM (Pengelolaan Hutan Bersama Masyarakat/Joint Forest Management) which is basically a partnership program. This study aims at describing the partnership program between a local organization (i.e. LMDH) and a government unit (i.e. RPH of Perhutani) within the PHBM program. The objectives of this study are to (a) describe the model of partnerships between LMDH and RPH Besowo for sustainable forest management and local community empowerment; (b) determine the contribution of the forest to the national economy and rural household income; and (c) determine the obstacles commonly found in Besowo forest that have to be faced during the implementation of the partnerships. The study shows that with good partnership between these two units, the prosperity of the local community can be enhanced and the forest preservation can be maintained. The model of the partnerships in this particular area in Indonesia is expected to be applicable as well in other rural areas in Indonesia, as well as in other developing countries.     

Role of remote sensing and community forestry to manage forests for the effective implementation of REDD+ mechanism: a case study on Cambodia

In this study, we have shown the importance of remote sensing applications and community forestry for forest management, discussed as a case study on Cambodian forest management. Curbing deforestation is necessary for the effective implementation of Reducing Emissions from Deforestation and forests Degradation (REDD+) mechanism and management of forest resources to support sustainable forest management plans. The updated information of the forest cover and forest biomass using advanced remote sensing techniques can be useful for selecting the suitable sites for planned thinning, reforestation, community forestry, and concession land, which eventually will help in controlling the deforestation in Cambodia. To overcome the limitations of remote sensing, an integrated approach of remote sensing and community forestry to monitor forests from local to national level has also been discussed.     

三峡库区森林植被恢复与可持续经营研究

系统的野外调查数据和历史资料分析结果表明,三峡库区森林植被在空间上发展不均匀,无明显垂直分带,且分布分散,人为干扰严重。目前,在70多个植被类型中,森林类型占25个,江岸两侧海拔800 m以下地区森林已经很少。森林类型中,马尾松、柏木林的分布面积最大,并在许多疏林中成为主要树种,主要是飞播或人工种植。库区大于25°的坡耕地占耕地面积的17.5％。库区薪炭林仅能满足农村用能总需求量的10.78％。不合理的土地利用方式和对森林的不合理砍伐导致脆弱的土壤系统和森林生态系统的严重退化、生产力下降和严重的水土流失。库区土壤年侵蚀量达到2.9亿t。三峡工程建设和移民安置对库区森林生态系统的压力和影响将是长期的。调查结果同时表明,库区植物生物多样性丰富,植物种类在5 032种以上,而且乡土树种多。分析认为,只要抓住三峡工程建设的契机,紧密结合国家天然林保护和退耕还林工程建设,充分利用良好的生物学基础,科学地封山育林,分带逐步恢复,同时,因地制宜,退耕还林,发展森林能源,建设多目标复合和多种模式并存的林业经营体系,发展经济,就能从根本上改善森林经营环境,实现森林恢复,形成合理布局的水库森林防护系统,促进三峡库区生态环境建设和可持续发展。     

联合国可持续发展行动的回顾与展望

该文以时间先后为顺序,系统总结了1972年人类环境会议以来,联合国为推进全球可持续发展所采取的重要行动,对取得的进展和存在的差距进行了评述。认为,人类环境会议特别是环发大会以来,联合国为实现全球经济社会可持续发展付出了巨大的努力,在许多领域推动形成了重要的共识和多边国际公约,促进了可持续发展伙伴关系的形成与发展,加快了许多国家和地区的可持续发展行动。但是,从目前来看,所取得的进展远低于需要达到的水平,突出地体现在千年发展目标进展缓慢、环发领域谈判举步维艰、国际履约明显不足、可持续发展伙伴关系的效果并不理想等。基于这一现实,本文认为"里约+20"大会应努力在如下四个方面取得进展:一是重振里约精神,加快已有政治承诺的落实;二是在坚持里约原则的前提下,围绕气候变化等重大全球性挑战做出新的政治承诺;三是在坚持里约原则的前提下,勾画出人类绿色发展的未来蓝图;四是促进以南南合作为重点的国家合作。     

湖北“两圈”区域发展可持续性评价与预测

利用可持续发展指数（SDI）对湖北“两圈”各市州发展现状进行了评价，而后利用9年的人均生物资源生态承载量年平均增长率、人口年平均增长率和足迹承载量比值年平均增长率及2006年相关数据对未来44年进行了预测。结果表明，截至2006年底，湖北省有一半以上国土面积的生物资源开采超过当地土地负荷，人均生物资源生态承载量持续下降，资源日益紧张，呈不可持续发展；武汉城市圈2006年生物资源生态足迹超出生物资源生态承载量的32%；鄂西生态文化旅游圈（简称：鄂西生态圈）除襄樊、荆州、荆门因人口多，生物资源生态足迹较大等原因导致SDI值较高外，其他市州的SDI值均较低；神农架的SDI最小；武汉城市圈人均生物资源生态承载量呈负增长，人口控制较好，足迹承载量比值增长较快；鄂西生态圈人均生物资源生态承载量呈负增长，增长速率大于武汉城市圈和湖北省，人口控制较差，足迹承载量比值增长较慢；按照现有发展模式，无论是武汉城市圈还是鄂西生态圈，无论其当前发展是可持续性还是不可持续的，未来他们都将进入不可持续的发展状态。因此，对“两圈”进行规划时要根据各自发展现状制定长期、科学的发展规划.     

Can post-2015 sustainable development goals survive neoliberalism? A critical examination of the sustainable development–neoliberalism nexus in developing countries

The Rio+20 summit of the United Nations in Brazil in 2012 committed governments to formulate a set of sustainable development goals (SDGs) that would be integrated into the Millennium Development Goals (MDGs) following its expiration in 2015. This decision has pushed sustainable development agenda into the limelight of development once again. Meanwhile, we note that the development agenda of many developing countries has been dominated by neoliberal orientation driven by market reforms, social inequality, and a move towards enhancing the economic competitiveness of the supply side of the economy. In this paper, we discuss the relationship between neoliberal economic agenda and sustainable development. We do so by examining how neoliberal policies of privatisation, trade liberalisation and reduction in governments spending stand to affect the attainment of sustainable development ideals and their implications on the post-2015 Sustainable Development Goals. The paper then suggests that relying solely on the mechanisms of the market in governing and allocating environmental resources is necessarily insufficient and problematic and therefore calls for a new approach—one which goes beyond just recognising the interdependency among social, environmental and economic goals and places issues of equity and addressing unfavourable power relations at the centre of interventions aimed at achieving the ideals of sustainable development.     

Corporations,Consumerism and Culpability: Sustainability in the British Press

Sustainability and sustainable development are prominent themes in international policy-making, corporate PR, news-media and academic scholarship. Its definitions are contested, however sustainability is associated with a three-pillar focus on economic development, environmental conservation and social justice, most recently espoused in the adoption of the UN Sustainable Development Goals in 2015. In spite of its common usage, there is little research about how sustainability is represented and refracted in public discourse in different national contexts. We examine British national press coverage of sustainability and sustainable development in 2015 in a cross-market sample of national newspapers. Our findings show that key international policy events and environmental and social justice frames are peripheral, while neoliberalism and neoliberal environmentalism vis-à-vis the promotion of technocratic solutions, corporate social responsibility and “sustainable” consumerism are the predominant frames through which the British news-media reports sustainability. This holds regardless of newspaper quality and ideological orientation.     

Community forestry management and livelihood development in northwest China: integration of governance, project design, and community participation

In projects of community development and natural resource management, local residents collaborate with government and NGOs on decisions about forest management and participate in programs designed to improve livelihoods while sustaining natural resources. This paper uses case studies and survey data in Gansu province of northwest China to explore social, ecological, and economic outcomes of community-based co-management (CBCM). Findings show that CBCM appears to have significantly increased livelihoods for local community residents overall. Forest condition and attitudes about forest conservation were also improved. However, economic benefits were not enjoyed uniformly within the communities because, although CBCM projects are nominally available to all, certain subgroups within communities are less likely to participate. Greater education, being married, and access to information are all strongly correlated with participation and thus the economic benefits of CBCM projects. Women, although they frequently participate in household decisions, are infrequent participants in CBCM projects, perhaps because project design does not meet their needs. Future improvements to CBCM project design should include increased access to information, education, and equitable treatment of diverse stakeholders in the decision-making process. Such improvements would likely lead to improvements in livelihoods as well as more sustainable forest management and conservation.     

The social dimension as a driver of sustainable development: the case of family farms in southeast Spain

The social pillar has often been treated as an ‘add on’ in sustainable development studies, and analyses of its ‘proactivity’ in economic, environmental, and social transformations to sustainability outcomes are scant. The present paper looks at the social dimension as a key driver of sustainable development. Social factors in the farming system in southeast Spain are analyzed to show how family farms and their networks can integrate socio-economic and eco-social goals, promoting the generation of synergies and trade-offs between the dimensions of sustainability. This study contributes to existing debate on the role of family farms in the framework of European rural development.     

林业生产性服务能促进农户林地规模经营吗?--基于林地流入视角的实证分析

厘清林业生产性服务对农户林地规模经营的影响,可为盘活集体林区林地资源、促进家庭林业发展提供决策参考。为考察林业生产性服务对林地规模经营的影响,首先构建了考虑林业生产性服务及林地规模的农户生产模型,通过理论分析后提出假设:林业生产性服务投入增加,将促进农户增加林地要素投入,即林业生产性服务对农户林地规模经营有正向影响。其次,基于福建500份经营商品林农户调查数据,利用Double-Hurdle模型及工具变量处理选择性偏差、遗漏变量及联立因果等引起的内生性问题,实证分析林业生产性服务对农户林地规模经营的影响。结果发现:不同类型的林业生产性服务对农户林地规模经营影响存在差异。其中,林业信贷服务对农户林地规模经营有正向影响,正规信贷与非正规信贷分别使农户林地流入概率提升19.6%、15.9%,使农户林地流入规模分别扩大66.8%、38.5%。林业物资与技术服务仅在是否流入林地阶段对农户林地规模经营有正向影响,使农户林地流入概率提升8.9%。林业劳动力服务仅在林地流入规模阶段对农户林地规模经营有正向影响,使得农户林地流入规模扩大66.9%。林业销售服务由于买方垄断特征对农户林地规模经营有负向影响,使农户林地流入概率降低12.3%,使农户林地流入规模缩减73.2%。因而,政府应有针对地激励和规范各类林业生产性服务发展,以更好地服务于集体林区家庭林业发展。
