Infrastructure is necessary to protect and provide the goods and services required by humans. As coastal green infrastructure (CGI) aims to respect and work with natural processes, it is a feasible response to mitigate or avoid the consequences of coastal squeeze. The concept of CGI is receiving increased attention of late due to the challenges facing us, such as climate change, population growth and the overexploitation of natural resources on the coast. Terms which may be applied to encourage the construction of infrastructure, or to minimize the responsibility for poorly made decisions, often induce misunderstanding. In this paper, the concept of CGI and its use in solving coastal problems is reordered. Four categories are proposed, according to the degree of naturalness of the project: Nature reclamation, Engineered ecosystems, Ecologically enhanced engineering, and De-engineering/Relocation. Existing coastal risk evaluation frameworks can be used to design many types of CGI. Key concepts, challenges and good practices for the holistic management of coastal squeeze are presented from the analysis of successful and unsuccessful CGI projects worldwide.

沿海绿色基础设施，以减轻沿海挤压

基础设施对于保护和提供人类所需的商品和服务是必不可少的。由于沿海绿色基础设施（CGI）旨在尊重自然过程并与自然过程一起工作，因此减轻或避免沿海挤压的后果是一种可行的应对措施。由于我们面临的挑战，例如气候变化，人口增长和沿海自然资源的过度开发，CGI的概念近来受到越来越多的关注。可能会被用来鼓励基础设施建设或将错误决策的责任降至最低的术语常常引起误解。本文对CGI的概念及其在解决沿海问题中的应用进行了重新排序。根据项目的自然程度，提出了四个类别：自然填海，工程生态系统，生态增强的工程和去工程/搬迁。现有的沿海风险评估框架可用于设计多种类型的CGI。通过对全球范围内成功和失败的CGI项目的分析，提出了对沿海挤压进行整体管理的关键概念，挑战和良好实践。
