Exploring International Perspective on Factors Affecting Urban Socio-Ecological Sustainability by Green Space Planning

Urban green space (UGS) is one of the most important components of urban systems to create sustainable cities. This crucial urban element performs many social and ecological functions to facilitate a better quality of life for urban residents. The main aim of this study is to identify the most critical factors contributing to cities' social and ecological sustainability through UGS planning and development. To achieve this aim, an integrated socio-ecological approach was followed to collect and analyse the data, which comprised context analysis and an international experts survey. Therefore, firstly, the main influencing factors for urban social and ecological sustainability that can be achieved by UGS planning were extracted by reviewing the related literature. In the next step, to find the most critical factors, an online international survey of academicians and experts drawn from a number of countries was conducted. Based on the experts' opinions, twenty-two factors out of sixty-five, including twelve social factors and ten ecological factors, achieved the highest scores. According to the results, the key factors of accessibility from the social sustainability category and protection from the ecological sustainability category play the most important roles in maximising the social and ecological benefits of UGS.
