The objective is to improve the adaptation capacity of cities and densely built areas in the 2 Seas region by co-creating and implementing innovative climate change adaptation solutions with local stakeholders. This will result in an increased adaptation capacity of densely built area’s in the 2 Seas region by at least 25,000 m3 as well as costs saving of 10 - 50% compared to the use of traditional adaptation investments. SPONGE paves the way for a wide rollout of these innovative participatory adaptation solutions to reduce the risks of and damage from urban flooding across the 2 Seas area at considerably lower costs.

• 7 complementary pilot actions to co-create and implement innovative, place based climate adaptation solutions with local stakeholders. The partners jointly plan, design, implement & evaluate the pilots
• 1 toolbox for stakeholder engagement in climate adaptation
• 1guidance pack for participative climate adaptation in densely built areas
• 1Cross border action plan to introduce participative local climate strategies

Involving local stakeholders in co-creation and implementing innovative climate adaptation measures brings local (water) authorities on new terrain. In our consortium we have partners with experience in alternative adaptation techniques, stakeholder mobilisation and co-creation of public interventions. By putting these capacities together in a cross border cooperation we create the opportunity to develop, pilot and demonstrate participative climate adaptation actions to increase the adaptation capacity of our partner cities and other densely built territories in the 2 Seas area.
