Barriers Beyond the Partners: Bureaucratic and Political Constraints to Implementing Joint Forest Management in Tamil Nadu,India

Whereas past research has treated co-management of common pool resources as if villagers and project implementing authorities were the only relevant actors, numerous external factors beyond the control of these two partners create barriers to successful co-management. This paper draws on discussions with Forest Department officials to examine the influence of these forces on the outcomes of Joint Forest Management (JFM) in Tamil Nadu, India. An empirical inquiry into the operational aspects of JFM indicates the important roles of political parties, powerful people, and other state institutions and functionaries as well as the flow of foreign funding. Further, the strong demand by local people for socio-economic development interventions as opposed to improvement of degraded forests belittles the role of the Forest Department relative to other departments. Numerous other conditioning factors and relationships are explored. The authors call for reforms in public governance to allow better participation of all the actors involved for this participatory management approach to succeed and sustain.     

Prenatal prediction of childhood-onset spinal muscular atrophy (SMA) in Turkish families

Childhood-onset spinal muscular atrophy (SMA) is one of the most common neurodegenerative genetic disorders. SMN1 is the SMA-determining gene deleted or mutated in the majority of SMA cases. There is no effective cure or treatment for this disease yet. Thus, the availability of prenatal testing is important. Here we report prenatal prediction for 68 fetuses in 63 Turkish SMA families using direct deletion analysis of the SMN1 gene by restriction digestion. The genotype of the index case was known in 40 families (Group A) but unknown in the remaining 23 families (Group B). A total of ten fetuses were predicted to be affected. Eight of these fetuses were derived from Group A and two of these fetuses were from Group B families. Two fetuses from the same family in Group A had the SMNhyb1 gene in addition to homozygous deletion of the NAIP gene. One fetus from Group A was homozygously deleted for only exon 8 of the SMN2 gene, and further analysis showed the presence of both the SMN1 and SMNhyb1 genes but not the SMN2 gene. In addition, one carrier with a homozygous deletion of only exon 8 of the SMN1 gene was detected to have a SMNhyb2 gene, which was also found in the fetus. To our knowledge, these are the first prenatal cases with SMNhyb genes. Follow-up studies demonstrated that the prenatal predictions and the phenotype of the fetuses correlated well in 33 type I pregnancies demonstrating that a careful molecular analysis of the SMN genes is very useful in predicting the phenotype of the fetus in families at risk for SMA.

我国固体废物的管理体制问题分析

随着经济的发展和城市化水平的提高,固体废物的产生量迅速膨胀,其已成为制约社会和经济持续健康发展的瓶颈.以政策过程为主线,主要在责任界定、政策制定、政策执行和效果监督等环节上对城市生活垃圾、工业固体废物、危险废物和进口固体废物这4种重要的固体废物管理中存在的问题进行分析.结果表明,城市生活垃圾和工业固体废物管理中最亟待解决的问题均在于管理责任机制不明确;危险废物管理中最显著的困难在于国内相关法律法规还不健全、存在监管漏洞;进口固体废物管理中关注的重点是电子垃圾非法贸易问题.针对以上问题,给出了相应的政策建议,以促进固体废物管理体制基础的完善.     

省域生态环境质量动态评价及差异研究

以2010~2015年30个省域为研究对象，采用“驱动力-压力-状态-影响-响应”框架构建评价指标体系，运用逐层纵横向拉开档次法确定指标权重，运用“时间度”和“熵值”法确定时间权重，构建TOWA-GA混合算子生态环境质量动态评价模型.结果表明：6a来，30个省域生态环境质量总体均值为0.837，整体呈好转趋势，但省域间差异明显.通过Theil指数分析发现，省域间总体差异下降了15.91%，人口密度和人口自然增长率是省域间差异的主要影响因素.     

Significant developments in sustainable development law and governance: A proposal

This article develops a practical proposal for progress on sustainable development law. It examines the prospects for an international sustainable development law to provide a framework for more effective, coherent governance. Sustainable development law is briefly defined and an analytical framework is provided. Different degrees of integration between economic, social and environmental law are described. Certain principles of international law related to sustainable development are also highlighted. It is argued that these principles may serve to guide law‐makers and jurists where social, economic and environmental law and policy conflict or overlap. Continuing, underlying questions of sustainable development governance are addressed and its global frameworks analysed. The article also focuses on the 2002 World Summit on Sustainable Development, held in Johannesburg in August‐September 2002, and its specific mandate for the United Nations Commission on Sustainable Development (UNCSD) to take related legal developments into account. The article advances a proposal: that governments, economic, social and environmental intergovernmental organizations and other actors establish a ‘network of inquiry’ with members from relevant groups, including legal and academic organizations, and other expert groups, in order to follow, research, analyse and debate legal developments in a balanced way.     

The city as a refuge for insect pollinators

Research on urban insect pollinators is changing views on the biological value and ecological importance of cities. The abundance and diversity of native bee species in urban landscapes that are absent in nearby rural lands evidence the biological value and ecological importance of cities and have implications for biodiversity conservation. Lagging behind this revised image of the city are urban conservation programs that historically have invested in education and outreach rather than programs designed to achieve high‐priority species conservation results. We synthesized research on urban bee species diversity and abundance to determine how urban conservation could be repositioned to better align with new views on the ecological importance of urban landscapes. Due to insect pollinators’ relatively small functional requirements—habitat range, life cycle, and nesting behavior—relative to larger mammals, we argue that pollinators put high‐priority and high‐impact urban conservation within reach. In a rapidly urbanizing world, transforming how environmental managers view the city can improve citizen engagement and contribute to the development of more sustainable urbanization.     

When and how to use Q methodology to understand perspectives in conservation research

Understanding human perspectives is critical in a range of conservation contexts, for example, in overcoming conflicts or developing projects that are acceptable to relevant stakeholders. The Q methodology is a unique semiquantitative technique used to explore human perspectives. It has been applied for decades in other disciplines and recently gained traction in conservation. This paper helps researchers assess when Q is useful for a given conservation question and what its use involves. To do so, we explained the steps necessary to conduct a Q study, from the research design to the interpretation of results. We provided recommendations to minimize biases in conducting a Q study, which can affect mostly when designing the study and collecting the data. We conducted a structured literature review of 52 studies to examine in what empirical conservation contexts Q has been used. Most studies were subnational or national cases, but some also address multinational or global questions. We found that Q has been applied to 4 broad types of conservation goals: addressing conflict, devising management alternatives, understanding policy acceptability, and critically reflecting on the values that implicitly influence research and practice. Through these applications, researchers found hidden views, understood opinions in depth and discovered points of consensus that facilitated unlocking difficult disagreements. The Q methodology has a clear procedure but is also flexible, allowing researchers explore long‐term views, or views about items other than statements, such as landscape images. We also found some inconsistencies in applying and, mainly, in reporting Q studies, whereby it was not possible to fully understand how the research was conducted or why some atypical research decisions had been taken in some studies. Accordingly, we suggest a reporting checklist.     

协同治理理论视角下连云港湾长制试点存在的问题及对策

近岸海域环境综合治理是典型的公共产品和公共服务,需要多个主体协同治理。连云港湾长制已实施两年多,虽取得了一定成效,但从协同治理理论来看,仍存在治理主体相对单一、公众参与不足问题。因此,今后应以协同治理理论为指导,形成多元的治理主体,树立各个治理主体的权威性,加强各治理主体的协同性,充分发挥各治理主体的积极性,共同推进湾长制的实施。

厌氧-准好氧联合型生物反应器填埋场产气规律的研究

通过将厌氧型生物反应器填埋场（ANBL）和准好氧矿化垃圾生物反应床（SAARB）串联,组成新型的厌氧-准好氧联合型生物反应器填埋场（AN-SABL）,研究其产气速率、产气量以及产气组分的变化规律,以期为填埋气体的收集、利用和处理提供理论依据.实验表明,AN-SABL中的厌氧填埋单元的产气受到了抑制,其中ANBL2号单元和ANBL3号单元的产气率分别为49 L.kg-1和39 L.kg-1,仅占ANBL1号的94.2%和75.0%,但提高回灌频率,能促进厌氧填埋单元的产气,其甲烷含量最大值可达到62.67%;ANBL夏季产气速率和产气量明显高于冬季,并以12 h为周期交替出现产气高峰;此外,AN-SABL能够促进其厌氧单元的硝化和反硝化作用,N2O的含量受季节和填埋场类型影响显著,其变化范围在0.001 7%～4.017 9%之间.ANBL的累积产气量在初始调整阶段呈对数增长,过渡酸化阶段呈线性增长,酸化产甲烷阶段呈指数增长.
