The Horizon 2020 project BINGO: Bringing INnovation to onGOing water management-a better future under climate change aims at providing practical knowledge and tools to end-users, water managers, decision and policy-makers affected by climate change to better cope with all climate projections, including droughts and floods.
Badalona (located along Catalonia’s northeast coast) is one of the 6 case studies of BINGO, where the main objective is to increase the urban resilience of the city towards floods and Combined Sewer Overflows (CSOs) problems in a context of climate change.
Climate change adaptation can be approached at different spatial scales, from national to local. However, as adaptation decisions are context-specific, local and regional stakeholders are particularly relevant when defining optimal and realistic adaptation strategies.
Key elements to construct a solid climate change adaptation strategy include: availability of sound knowledge and information to support decision-making processes; commitment of cities to take climate action; existence of a good governance, competences and authority to regulate climate-relevant issues and availability of economic resources to reach adaptation strategy.
Analysing such elements at Badalona scale we can conclude that:
- BINGO project has provided a solid knowledge basis (and tools to reach) climate change impacts assessment, including an estimation of direct and indirect damages on citizens, buildings, vehicles and bathing waters which has contributed to raise awareness on potential climate change impacts at local scale
- Badalona city has a clear commitment towards climate action due to its accession to the Covenant of Mayors for Climate Change Adaptation
- Regarding governance and competences, several stakeholders are involved in adaptation decisions concerning the urban water cycle, these include: the Badalona city Council, the regional administration of Metropolitan Area of Barcelona (AMB), the water managers (Aigües de Barcelona), the Catalan Water agency, and some others.
- Finally, one of the main constraints to develop such adaptation strategies is clearly the availability of economic resources to put into practice such solutions.
For each one of the case studies of BINGO project, an innovative methodology, the Communities of Practices (CoP) have been created as a tool to exchange information and to involve stakeholders in decision-making processes such as the definition of the adaptation strategies.
One of the results of this CoP in Badalona is the definition of 5 adaptation measures, agreed by all the key stakeholders together with a realistic roadmap to implement them, including the identification of responsibilities, pros and cons, action plan or cost.
