Abstract
Blue-Green Cities manage flood risk by recreating more naturally oriented water cycles in urban areas through the restoration of natural drainage channels, reduction in impervious surfaces and implementation of Blue-Green Infrastructure (BGI - for example, swales, wetlands, green roofs) to enhance infiltration, attenuation and surface storage of water. Blue-Green Cities work synergistically to mimic predevelopment hydrology while generating multiple co-benefits to the environment, society and economy. The chapter expands on the Blue-Green City concept, providing an overview of existing research in this field. International examples show how the barriers hindering progression towards Blue-Green Cities are being overcome. Emerging research into adaptation pathways, natural capital accounting and social practice approaches for understanding community preferences demonstrate how research into Blue-Green Cities is moving beyond hydrodynamic modelling to consider decision-making under future uncertainty, the inclusion of environment and social benefits in business cases and the pivotal role of community preferences in designing blue-green systems.
