15 CLIMATE ADAPTATION PLAN Towards a Climate Resilient City Bibliotheek

16 CLIMATE ADAPTATION PLAN Towards a Climate Resilient City Cooling infrastructure Greening the city Green blue network Less soil sealing Creating space for water

17 CLIMATE ADAPTATION PLAN Towards a Climate Resilient City Ghent Climate Adaptation Plan The pillars of the Ghent climate adaptation strategy: 1. Political support base and broadening within the city organization 2. Knowledge build-up regarding climate scenarios, impact, and vulnerability of Ghent 3. Knowledge build-up regarding possible measures at the local level 4. Integration into city policy plans, instruments, and processes 5. Implementation by means of example projects 6. Targeted communication and awareness-raising 7. Partnerships and multi-stakeholder approach 8. Monitoring and evaluation Bibliotheek Ghent Climate Adaptation Plan

18 CLIMATE ADAPTATION PLAN Towards a Climate Resilient City Focus on 2 major topics Urban heat Urban water system (water nuissance and drought) Focus on spatial structural measures and awareness

19 ADAPTATION MEASURES Green roofs Building code fornew projects Allflat roofsnotneededforrain water collection and re use Bibliotheek Subsidy programme for existing buildings(31 /m²)

20 ADAPTATION MEASURES Green roofs EUR for a roof stability study - minimum conditions for the substrate: 6 cm thick - higher subsidy for high-quality green roofs: - min. 50 l / m² and more than sedum plats -> 45 / m² - max / building N projects 551 Subsidy amount Surface green roofs m² Movie on Youtube
