Cost–benefit analysis of beach-cast harvest: Closing land-marine nutrient loops in the Baltic Sea region

Harvesting beach-cast can help mitigate marine eutrophication by closing land-marine nutrient loops and provide a blue biomass raw material for the bioeconomy. Cost–benefit analysis was applied to harvest activities during 2009–2018 on the island of Gotland in the Baltic Sea, highlighting benefits such as nutrient removal from the marine system and improved recreational opportunities as well as costs of using inputs necessary for harvest. The results indicate that the activities entailed a net gain to society, lending substance to continued funding for harvests on Gotland and assessments of upscaling of harvest activities to other areas in Sweden and elsewhere. The lessons learnt from the considerable harvest experience on Gotland should be utilized for developing concrete guidelines for carrying out sustainable harvest practice, paying due attention to local conditions but also to what can be generalized to a wider national and international context.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01641-8.     

上海与东京生活垃圾处理回收体系之比较

进入21世纪，上海提出建设循环经济型国际大都市的战略目标，其中很重要的一个领域就是要构筑高效、实用的生活垃圾处理回收体系。文章分析了上海与东京现行的生活垃圾处理回收体系的特点，并对二者进行了比较。发现上海体系存在着垃圾处理方式的简单化，垃圾分类收集形式化，废品回收无序化，对策视点局限性和管理系统封闭性等诸多缺陷。通过借鉴东京体系的成功经验，建议实施法律和经济的手段。不断改进和完善上海体系。     

北京市发展循环经济的行动策略研究

在世界各国积极发展循环经济的大环境下,中国也将其纳入战略性决策。北京作为中国的首都,凭借其得天独厚的地理和资源优势,各方面发展都处于领先地位,循环经济亦是如此。北京市在循环经济发展过程中成果显著,但也难免存在疏漏和不足之处。本文以循环经济理论为基础,通过分析北京市综合发展状况,建立了北京市消费能源总量与北京市人均GDP之间的模型关系,总结其发展循环经济的得与失,并提出切实可行的政策建议。

生态全息论对发展循环经济的启示

作者根据生态全息的理论，提出了推行工业生态系统和循环经济的具体步骤。发展循环经济是一个大的系统工程，涉及到经济、环境、社会的各个层面，涉及到国民经济的各个行业和企业，必须进行系统的研究和战略部署，理念不能作为目标，没有政府的支持和企业的积极参与是不行的。     

连云港市工业循环经济发展趋势评价

依据工业循环经济发展的基本原则,构建了工业发展水平、资源减量利用、资源再利用和污染物减量排放4类共18项指标在内的工业循环经济发展评价指标体系。运用层次分析法(AHP),测算权重,对连云港市2006~2010年的工业循环经济发展状况进行了评价。结果表明,连云港市整体的工业循环经济发展水平呈先增长,再平稳,后增长的趋势,其中资源减量利用水平和污染物的减量排放水平呈逐年上升的良好势头,但资源再利用水平不高,有逐年下降的发展趋势。     

Putting a circular economy into practice in China

Promoting a circular economy has been identified as China’s basic national policy, according to the recently enacted 11th five-year plan for China’s economic and social development. Because of the importance of the development strategy used for this purpose, an implementation framework is proposed in this paper. First, a program is suggested for practically implementing a circular economy in China to serve as a demonstration, beginning at the level of enterprises, then industrial parks, then expanding to cities and regions, thus enabling accumulation of experience to facilitate reasonable decision-making at each successive step. Legislation is also urgent. Certain issues involving legislation, for example the rules the law requires, maneuverability, public involvement, and referencing of developed countries’ experiences, must be effectively addressed. Finally, a scientific and effective assessment system should be developed to obtain accurate information and improve guidance. Assessment indices should include an economic development index, a green development index, and a human development index.
