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.     

Estimating the Recreational-Use Value for Hiking in Bellenden Ker National Park, Australia

The recreational-use value of hiking in the Bellenden Ker National Park, Australia has been estimated using a zonal travel cost model. Multiple destination visitors have been accounted for by converting visitors’ own ordinal ranking of the various sites visited to numerical weights, using an expected-value approach. The value of hiking and camping in this national park was found to be $AUS 250,825 per year, or $AUS 144,45 per visitor per year, which is similar to findings from other studies valuing recreational benefits. The management of the park can use these estimates when considering the introduction of a system of user pays fees. In addition, they might be important when decisions need to be made about the allocation of resources for maintenance or upgrade of tracks and facilities.     

Relationship Between Tourism Development and Vegetated Landscapes in Luya Mountain Nature Reserve, Shanxi, China

The relationship between tourism development and vegetated landscapes is analyzed for the Luya Mountain Nature Reserve (LMNR), Shanxi, China, in this study. Indices such as Sensitive Level (SL), Landscape Importance Value (LIV), information index of biodiversity (H’), Shade-tolerant Species Proportion (SSP), and Tourism Influencing Index (TII) are used to characterize vegetated landscapes, the impact of tourism, and their relationship. Their relationship is studied by Two-Way Indicator Species Analysis (TWINSPAN) and Detrended Correspondence Analysis (DCA). TWINSPAN gives correct and rapid partition to the classification, and DCA ordination shows the changing tendency of all vegetation types based on tourism development. These results reflect the ecological relationship between tourism development and vegetated landscapes. In Luya Mountain Nature Reserve, most plant communities are in good or medium condition, which shows that these vegetated landscapes can support more tourism. However, the occurrence of the bad condition shows that there is a severe contradiction between tourism development and vegetated landscapes.     

天山乌鲁木齐河源1号冰川区气溶胶水溶性离子变化特征及来源分析

基于2007年4、8和10月这3个时段不同季节的野外考察取样和实验室分析测试,探讨了天山乌鲁木齐河源1号冰川区气溶胶样品中水溶性离子成分的浓度组成、变化特征及其可能来源.结果表明,气溶胶水溶性离子平均浓度为2.76μg·m-3,化学组成以Ca2+、NO-3和SO2-4为主.Ca2+、SO2-4、NH+4、Na+、Mg2+、Cl-在春、夏、秋这3个季节的变化趋势与总离子浓度的变化趋势一致,均为夏季最高、秋季次之、春季最低,而K+与NO-3却呈现出秋季最高、夏季和春季浓度次之的季节变化特征.分析认为,气溶胶中Ca2+、Na+、Mg2+、K+和Cl-主要可能来自陆源矿物;而NO-3和NH+4则很大程度上以人为源为主.并且发现,SO2-4可能同时受陆地源与人类活动来源的影响.     

扎当冰川雪坑中不同粒径微粒元素和矿物组成特征

为了研究雪冰中不溶性微粒的矿物和元素组成及其来源,2009年5月和7月在念青唐古拉山扎当冰川垭口采集了2个雪坑样品,采用质子激发X荧光分析（PIXE）和X射线衍射定量分析方法（XRD）测定了不同季节粗细微粒（d〉10μm和0.22μm     

江西省陆地生态系统氮平衡的时空分布规律研究

利用系统物质平衡模型,对1995-2005年江西省陆地生态系统的N收支平衡进行了核算,并分析了不同来源N收支量的时间序列特征以及N盈余强度的空间分布特征,探讨了自然灾害和政策实施对N平衡的影响.结果表明:江西省陆地生态系统的N输入量变化范围是(155.5-184.2)×107kg·a-1,平均值为168.5 ×107 ...     

祁连山老虎沟12号冰川积雪中飞灰颗粒物的特征

冰川积雪中的飞灰颗粒物可指示由大气沉降的人类活动污染物.本研究基于2012年6月在青藏高原东北缘的祁连山老虎沟12号冰川夏季野外观测取样、实验室扫描电子显微镜与X射线能谱仪联用系统(SEM-EDX)分析了积雪粉尘中球形颗粒物的特征信息,以弄清冰川区沉降的球形飞灰颗粒物的理化特征及其环境意义.结果表明,在所选取的雪层不同深度的9个积雪样品中,都存在着一定数量的飞灰颗粒,这些颗粒物通常是人类生产活动中的化石燃料高温燃烧所形成的.基于EDX能谱分析了飞灰颗粒物的化学元素成分组成,认为沉积在祁连山冰川积雪中的飞灰主要分为3种类型,分别为"富Si类"、"富Fe类"和"富Ti类"颗粒物.总体上,"富Si类"和"富Fe类"颗粒占了球形飞灰颗粒的绝大部分.这些不同组分的飞灰代表了污染物的不同生产活动来源,其平均粒径要相对大于雪层中自然来源的所有矿物粉尘颗粒物,反映了大气传输远距离中密度对粉尘颗粒的重要性.结合NOAA Hysplit气团后向传输轨迹分析认为,中亚地区和我国新疆地区城市、及研究区周边的工业燃烧物通过大气传输是祁连山老虎沟12号冰川积雪中飞灰颗粒的主要可能来源.

What happened to the Second World? Earthquakes and postsocialism in Kazakhstan

There is an assumption that with the disintegration of the Soviet Union, the Second World ceased to exist. Yet the demise of the Communist bloc as a geopolitical reality did not mean that it stopped exerting a defining influence over how people think and behave. This article examines how the postsocialist state in Kazakhstan deals with potential crises such as earthquakes and the extent to which the Soviet legacy still shapes intellectual debates, state structures, and civil society organisations in in that country. Drawing on fieldwork and interviews, this paper re-examines the Second World in its historical context and re-establishes it as a conceptual framework for considering disaster risk reduction in the former Soviet bloc. It argues that it is essential to pay attention to this legacy in Kazakhstan both in policy and practice if earthquake risk reduction is to be made more effective.
