Shifting Baselines: Conveying Climate Change in Popular Music

Popular music is a generation-specific zeitgeist, while music affords otherwise unobtainable engagement with environmental themes. Despite being the most widespread form of music there is a paucity of scholarship on climate change vis-à-vis popular music. In turn, this article explores how popular music may provide a soundtrack that narrates the rapidity of contemporary biophysical change. Approaches of conveying versus communicating climate change in music are considered across a spectrum of musical forms, from contemporary and historical popular music to contemporary classical music and sound art. The article applies the framework of shifting baselines to music engaged with environmental change in order to formulate a closer relationship between objective and quantitative intergenerational biophysical change and subjective and qualitative socio-cultural change. To cease losing track of such inexorable degradation, the article speculates on future musical forms that may obviate such intergenerational myopia by conveying and/or communicating the unprecedented rapidity of biophysical change.     

Preserving Wilderness or Protecting Homelands? Intersections and Divergences in Activist Discourses About Mining in Ontario’s Far North

Northern Ontario’s Ring of Fire/Wawangajing controversy constitutes a complex site of debate about the risks and benefits of mining in an area of major ecological significance that is also the ancestral territory of nine First Nation communities. This paper investigates the rhetorical alignments and divergences in public calls by Matawa First Nations tribal council and the Ontario Wildlands League for stronger environmental assessment of mining projects than that favoured by the Canadian government. Tracing the terminologies each group uses to describe the affected region and its inhabitants in its activist rhetoric about EA offers insight into the contingent, shifting ways in which wilderness advocacy and Indigenous justice discourses may speak together yet distinctly within contemporary environmental-natural resource disputes.     

环境监测点位“组合校验码”编码模型及编码管理系统设计

分析了环境监测点位编码管理中存在的问题,提出科学合理的编码应该是具有科学性、唯一性、稳定性、简明性、规范性、可扩展性等特点。设计了一种简单"组合校验码"模型来适应不同环境要素类型的环境监测工作需要。同时,设计了一套覆盖各层级环境监测机构,各种环境要素类型,适应市场化监测服务,满足不同点位管控类别的编码管理系统来支撑"组合校验码"模型的使用,通过该系统可以有效解决环境监测数据集成程度低、共享困难等问题。     

我国污染物总量控制制度改革的思考

污染物总量控制制度是我国环境保护制度的重要组成部分。结合污染物总量控制制度的实施现状,分析实施过程中减排基数、核算体系、责任主体等方面存在的问题。提出,改革现行污染物总量控制制度,将总量控制与改革中的排污许可制相融合,落实企业主体责任,将总量指标与环境质量改善挂钩,建立差异化的减排核算体系,并加强日常监管,达到改善环境质量的目标。     

浅谈县级环境监测质量管理工作现状及对策

当前环保系统垂直改革稳步推进,县级环境监测质量管理工作也迎来新的机遇与挑战。从县级环境监测站质量管理工作现状着手,分析新形势下存在质量管理体系有效性缺乏、现场监测过程质量管理薄弱、质量管理意识尚待提高等问题。提出,应从加强体系建设、提高现场监测水平、强化考核培训力度等方面改进县级环境监测质量管理工作水平。     

Double Green Process: a low environmental impact method for recycling of CdTe,a-Si and CIS/CIGS thin-film photovoltaic modules

On the basis of the method for managing the end of life of CdTe photovoltaic panels previously proposed by the authors, a new method for the recycling of all types of thin-film panels (CdTe, a-Si and CIS/CIGS) has been developed and optimised under a research project founded by Enel Foundation and CRUI Foundation. The DGP process has been developed through a feasibility study carried out from three points of view: technical, environmental and economic. The process is composed by two sub-processes matched to each other, one suitable for CdTe panels (named DGPa) and the other one for a-Si and CIS/CIGS panels (DGPb). The Double Green Panel process is based mainly on mechanical treatments with a minimum use of chemicals and it is characterised by a greater level of automation and a high flexibility in production capacity. The potential environmental impacts of various configurations of the DGP process have been extensively analysed with LCA tool in order to develop an environmentally friendly process. The economic feasibility has been assessed through the Discounted Cash Flow Analysis (DCFA) method. The revenues associated to the recovery of valuable and common materials and the recycling costs have been taken into account.     

环境监测技术服务社会化的政策文本研究

以部分省(市)颁布的29份环境监测技术服务社会化政策为研究样本,将市场准入、监测领域、运行管理和监督制裁作为政策文本的分析框架进行计量分析。部分省(市)相关规定具有一定的创新性,使以往混乱的社会环境监测技术服务市场进一步规范化;但多数省(市)的环境监测技术服务社会化政策存在市场准入条件苛刻、监测领域有待放开、运行管理模式僵化、监督制裁手段单一等难题。最后提出放宽市场准入条件、有序开放监测领域、构建多元管理模式、完善监督制裁体系等4项建议对上述难题予以回应。     

无碴轨列车运行引起的环境振动影响评价

对遂渝高速铁路无碴轨道试验段客车运行引起的环境振动进行了现场实测,根据实验数据分析得知:环境振动强度随距离增大而减小,随车速增大而增大,但车厢数量对环境振动强度影响不明显;环境振动主要频率范围为30～120 Hz,距轨道距离、车速、车厢数量对振动主要频率影响不显著;在轨道两侧31.9 m处,速度超过104.7 km/h列车环境振动强度超过GB 10070-1988要求,须采取措施隔振。     

北京和上海典型复合包装废物处置环境影响比较

采用生命周期评价法研究比较了北京和上海两地纸塑铝复合包装处置阶段的环境影响。通过现场和资料调研的方式获得此阶段的能量物质的输入输出和环境外排数据。结果表明:北京和上海两地纸塑铝复合包装处置阶段的环境影响潜值分别为-0.428 Pt和9.776 Pt,其主要集中在气候变化、土地占用和无机物对健康的损害三方面;每提高10%的回收率,其环境影响潜值北京和上海可分别降低5.446 Pt和5.799 Pt;上海地区纸塑铝复合包装处置阶段对环境的影响在任何同回收率的情况都要高于北京地区,其主要原因是上海地区填埋产生的温室气体释放量过大和再生企业距离打包点较远。
