Chapter 21: Green infrastructure and regeneration of brownfield land
Green infrastructure has become an integral component of land regeneration in many parts of the world. Introducing greenspace into urban design can offer a range of goods and services which are increasingly regarded as essential for modern living. In addition to traditional goods and services, vegetation on brownfield land can stabilise unstable and potentially polluting substrates and demonstrate the sense of regeneration purpose. The technical challenges associated with revegetating brownfield land are now comparatively well understood and worldwide there are many examples of very good practice. However, the ‘greening’ process is complex and the results are often only partially successful. Choice of appropriate vegetation must reflect the substrate and landform on offer – the use of non-native vegetation should be considered alongside native forms. It is important to understand both the dynamic nature of ecosystems and the changing needs for vegetation as regeneration proceeds. Increasingly, the spatial context of greenspace, its connectivity and relationship with buildings and watercourses need to be considered. The human and economic dimensions of greenspace on brownfield land must also be understood in order to establish forms which are sustainable into the future.
