Nature-based Solutions for Urban Climate Change Adaption: Barcelona’s Experience

Due to the intensified climate warming trend, adapting to it has become an important challenge for current urban development. In this context, nature-based solutions (NbS) have been proposed and used in urban planning and landscape architecture design. NbS can use nature approaches to enhance urban adaptability and disaster resilience, coordinate social and environment contradiction and promote sustainable development of cities. Nowadays, the research of NbS in foreign countries is focusing on the application, while China is still paying attentions to the theoretical interpretation, especially lacking of systematic experience analysis. Based on the NbS theory, the paper takes Barcelona as an example, summarizes the multiple benefits of NbS application in urban areas and statistics of various nature-based plans such as Barcelona climate plan and green infrastructure plan, and analyzes their implementation methods, system advantages and implementation characteristics. Through summarizing the practical experience of NbS in Barcelona, the papers aims to provide reference for the development of natural-based solutions in our cities in the future.
