Sea-Level Rise Risk Communication: Public Understanding,Risk Perception,and Attitudes about Information

We present the results of a study using a document-based evaluation method to better understand how residents in vulnerable coastal areas respond to risk communications about sea-level rise (SLR) and to determine whether communications localized for specific populations improve reception. Similar to climate change communication, SLR risk communication presents challenges involving complex science, uncertainty, invisibility, and politicization. To be comprehensible and persuasive, risk messages must be appropriately framed and visually compelling and must take into account risk perceptions and diverse viewpoints. Our approach involves assessing people's encounters with actual risk messages to determine their reactions and responses. Participants in this study had difficulty understanding information and expressed attitudes including fear, fatalism, skepticism, and loss. SLR risks were also perceived as both temporally and spatially distant, creating a challenge for communicators trying to convey a sense of urgency. We conclude by considering the implications of audience-focused research for SLR risk communication.     

论环境公共决策中风险沟通的法律实现——以预防型环境群体性事件为视角

当前我国环境群体性事件呈高发态势。根据引发事件事实状态的不同可将其分为事前预防型环境群体性事件和事后救济型环境群体性事件。预防型环境群体性事件中公众所抵制的是有关环境风险的决策结果,实质上是在主张环境公共决策过程中认知风险的权利。着眼于预防型环境群体性事件所针对的环境公共决策过程,主要运用理论分析、规范分析、比较分析的方法,从行政决策权的行使与公众参与权利的实现入手,探究环境公共决策无法取得实质合法性的根源,寻求化解之法治路径。当前环境公共决策在结构和程序上呈现出封闭性,与决策结果具有直接利害关系的公众被排除在外,其认知风险的权利得不到有效实现,风险沟通不畅导致社会可接受的风险共识不能形成,环境公共决策无法取得实质合法性,引发预防型环境群体性事件增多。由于环境风险的不确定性特征,环境公共决策中专家的理性地位被动摇,公众参与环境决策的诉求更为强烈,其对风险的认知直接决定了对最终决策结果的认可和接受程度,政府无法独占风险决策地位。在社会层面形成具体风险认知的共识以便决策结果获得普遍的认同和接受成为环境公共决策取得实质合法性的必要条件。化解预防型环境群体性事件,需要在环境公共决策过程中进行有效的风险沟通。为此,环境法应当将公众作为环境决策的合作者,要求决策者主动、全面公开决策所依据的事实和理由,对公众意见给予及时充分的回应,寻求其理解和支持;实现环境信息公开的风险沟通功能;通过程序性的设计促进风险沟通的实现,保障公众参与的有效性。当前有关立法已反映出对风险沟通的重视,但只是萌芽。     

Climate Services and Communication for Development: The Role of Early Career Researchers in Advancing the Debate

Climate services entail providing timely and tailored climate information to end-users in order to facilitate and improve decision-making processes. Climate services are instrumental in socio-economic development and benefit substantially from interdisciplinary collaborations, particularly when including Early Career Researchers (ECRs). This commentary critically discusses deliberations from an interdisciplinary workshop involving ECRs from the United Kingdom and South Africa in 2017, to discuss issues in climate adaptation and climate services development in water resources, food security and agriculture. Outcomes from the discussions revolved around key issues somewhat marginalized within the broader climate service discourse. This commentary discusses what constitutes “effective” communication, framings (user framings, mental models, narratives, co-production) and ethical dimensions in developing climate services that can best serve end-users. It also reflects on how ECRs can help tackle these important thematic areas and advance the discourse on climate services.     

中国西部生态脆弱区产业结构调整的污染风险分析——以青海省为例

实现产业结构的调整升级是当今世界各国经济发展的普遍趋势,也是提升经济增长速度和水平的有效途径。青海省作为我国西部重要省份之一,不仅经济发展水平相对落后,而且生态环境也十分脆弱。随着西部大开发进程的不断推进,青海省经济加速发展,由此产生的污染风险也日趋提高。因此,研究青海省产业结构调整对提炼西部生态脆弱区协调经济增长与污染排放的关系并实现污染风险的有效监管具有重大意义。本文依据经济增长-环境质量回归模型研究了青海省产业结构升级与污染物排放的关系,发现青海省经济增长与污染物排放之间存在倒U型曲线关系。研究发现,青海省仍然处于污染物排放随经济增长而增长的阶段,且距离拐点仍有一定的距离。此外,本文分析了青海省不同产业随时间的变化趋势,虽然三大产业均有增长的态势,但是各占GDP比例变化却各不相同。其中,第一产业的比例不断下降,第二产业的比例不断增长,而第三产业在增长到一定比例后,有小幅减少的趋势。在此基础上,本文利用青海省不同产业占全国相同产业的比例,分析了青海省产业结构的变化趋势,并利用环境投入-产出模型计算了产业结构调整和升级过程中造成的污染物排放量,评价了产业结构升级可能带来的污染风险。虽然青海省第一产业占该区域GDP比例呈减少态势,但占全国比例并未发生明显变化,这表明了青海省农林牧渔业的发展趋势和速度基本与全国平均水平持平;第二产业占全国比例大部分呈减少的态势,而第三产业却有一定的增长态势,这在一定程度上反映了青海省产业发展正在向加大第三产业的发展并控制污染较严重的第二产业的发展的方向转变。产业结构的提升对不同产业污染物的排放也产生了不同的影响。其中,机械电子设备制造业、住宿餐饮和零售业和房地及租赁产业的提升导致了污染物排放小幅增长,而其他产业尤其是建筑业、金属制品业等的扩张则对污染物排放均有不同程度的抑制作用。因此,虽然其经济发展会在一定程度上加重环境污染风险,并且污染排放量会随经济的进一步发展而不断加大,但2002-2007年青海省产业结构变化对废水、废气等污染的排放产生了一定的控制作用,从而降低了青海省环境污染的风险。研究结论为青海省调整产业结构以抑制环境污染风险并保障区域经济发展和环境保护的协调提供重要的决策参考信息。
