The purpose of this study is to clarify the background and objective of green infrastructure implementation, opportunities and method of green infrastructure installation, implementation system of green infrastructure, funding, and policy context of green infrastructure implementation in selected green infrastructure-related projects that were carried out for the main purpose of adapting climate change, particularly alleviating a flood risk by using ecosystem service in England. And through above study, we preliminarily discussed the things that contribute to green infrastructure introduction into Japan. In particular, we understood the actual conditions of green infrastructure implementation through bibliographic survey and fieldwork on distinguishing examples of green infrastructure installation into each three types of the site (road, river and public park) that were selected by taking specialist’s opinion and the information from authoritative sources into consideration.
This study investigated the Green Infrastructure (GI) planning in the UK’s Queen Elizabeth Olympic Park was implemented, by the assumption that GI can create habitats under the environment strongly influenced by human impact. For example, the river, wetland/marshes within the floodplain, Sustainable Urban Drainage System (SUDS) were combined with GI planning to contribute to climate change adaptation. In the Park, rivers and wetland/marshes were also considered as GI. Habitats were created not only in the area of reedbed and wet woodland, but also in small-scale GI installation like soft swale. Here, it is significant that the habitat creation can be considered as not only the purpose of the Biodiversity Action Plan (BAP) but also the means to make GI function. On the other hand, GI implementation can be understood as a measure to create particular habitats. This study showed the relationship between GI planning and habitat creation. In the future it should be analyzed in detail how walkway, cycleway and greenway were designed as GI.
