The combined effects of climate change and increasing urbanization call for a change of paradigm for planning, maintenance and management of new urban developments and retrofitting of existing ones to maximize ecosystem services and increase resilience to the adverse climate change effects. This presentation will discuss synergies of the EU Climate-KIC Innovation Blue Green Dream (BGD) Project in promoting the BGD demonstration and training sites established in participating European countries. The BGD demonstration and training sites show clear benefits when blue and green infrastructures are considered together. These sites present a unique opportunity for community learning and dissemination. Their development and running acts as a hub for engineers, architects, planners and modellers to come together in their design and implementation stage. This process, being captured in a variety of media, creates a corpus of knowledge, anchored in specific examples of different scales, types and dimensions. During the EU Climate-KIC Innovation Blue Green Dream Project, this corpus of knowledge will be used to develop dissemination and training materials whose content will be customised to fit urgent societal needs.
