Barriers to resilience were found to be overall common among the projects of the 6 cities, although of different weight depending on the city. To their majority, they referred to a lack of understanding of what city resilience under climate extremes means in practice, as well as to a partial knowledge of the practices and tools leading to resilience under climate extremes.
IGNITION developed a Living Lab to act as an experimentation environment, but also as a demonstration and dissemination of innovative new products and services linked to Nature-Based Solutions (green walls, street trees, urban green space, green roofs, sustainable drainage systems). Partners organised multiple activities and tours, inviting various partners such as the highway authority, property developers, mall owners and elected representatives. These tours aimed to challenge their assumptions and convince them that multiple, cost-effective climate adaptation solutions exist.
In RESILIO, two Innovation Labs were developed. These were roofs for experimenting with the innovative smart Blue-Green roof systems, as well as demonstration centers serving as community spaces for educational and interactive events. RESILIO also linked the installation of the Blue-Green roofs with the social housing program, thus demonstrating the capacity of a climate resilience measure to support social cohesion. It pushed the action of the municipality beyond traditional publicly owned spaces. Some of the UIA adaptation projects have been opportunities to open spaces to new usages and to approach spaces differently beyond traditional occupancy. Some of the RESILIO rooftops are now open to the local communities, enabling them to access spaces previously closed. The OASIS schools offer their playgrounds to the local community beyond school hours as neighbourhood parks. This required extensive collaboration between Paris’ city departments to unlock issues arounds responsibilities, safety, maintenance.
OASIS also aligned to the Paris Climate Adaptation Plan to give space to a new model for urban planning, prioritizing green and sustainable development with a strong social dimension. Furthermore, it worked on innovation procurement processes to integrate eco-innovative products into city planning, for doing so, a reshuffle of the city’s technical processes was promoted. These changes to the procurement guidelines can open the way to more green procurements in the longer term in the municipality.
