当地资源管理中多学科冲突分析和冲突减缓

在瑞典的研究项目"海岸带可持续管理"中,迄今已完成了几项冲突研究.鉴于这些研究的详细结果是分别发表的,本文综述这些冲突研究的重要成果,以及总结和概要讨论海岸带可持续管理资源和冲突研究的方法和主要成果.在关于环境和资源利用冲突的多学科和理论上分析以后,提出了海岸带可持续管理中所使用的方法,即相关利益方和冲突的结合分析.可归纳为以下主要4点:①绘制诸利益相关者及其利益图;②分析所有冲突;③研制减缓冲突和与利益相关者合作的方法;④把这些内容综合到一个系统之下,以便进行自然资源管理.在瑞典东、西海岸已经开展了一些资源利用冲突的范例研究,包括沿岸渔业、贻贝养殖、海岸带规划及具体的冲突,例如种群保护(海豹)和沿岸渔业之间冲突.研究人员既作为专家也作为冲突当事方参与.在冲突研究中,科学家作为利益相关者其作用值得特别注意.冲突管理不仅是为了解决目前的冲突,而且还作为资源综合管理系统的一部分,其中可开展知识转让;建立制度;科学、政治和行政等部门共同学习;以及科学家和资源用户之间合作.

Using chemical process simulation to design industrial ecosystems

Chemical process simulation (CPS) software has been widely used by chemical (process) engineers to design, test, optimise, and integrate process plants. It is expected that industrial ecologists to bring these same problem-solving benefits to the design and operation of industrial ecosystems can use CPS. This paper provides industrial ecology researchers and practitioners with an introduction to CPS and an overview of chemical engineering design principles. The paper highlights recent research showing that CPS can be used to model industrial ecosystems, and discusses the benefits of using CPS to address some of the technical challenges facing companies participating in an industrial ecosystem. CPS can be used to (i) quantitatively evaluate and compare the potential environmental and financial benefits of material and energy linkages; (ii) solve general design, retrofit, or operational problems; (iii) help to identify complex and often counter-intuitive solutions; and (iv) evaluate what-if scenarios. CPS should be a useful addition to the industrial ecology toolbox.
