NEXUS APPROACH TO ADAPTATION OF URBAN AREAS TO CLIMATE CHANGES Blue Green Dream’s paradigm for the future spatial planning

Prof Čedo Maksimović, Imperial College London

About myself

KEY QUESTIONS answered in this lecture

2. Do current management approaches adequately address implications of climate change, e.g. frequency, intensity and duration of floods and droughts?

3. Do we have the tools (e.g. models) to integrate sectors anddisciplines for integrated management approaches?

4. Will new or improved technologies (and which) be required or at least be helpful to foster integrated management approaches?Do we need new (e.g. specific modelling tools)?

6. Overall: is there a need for more research on the nexus?8. What are and where are best practice examples of monitoring

programmes (quantity and quality of water, soil characteristics, land use, waste sites) at local/national/regional level?

To BGD or not to BGD, that is not the question now

Capital cost benefits:- Cheaper water systems- Cheaper renewable energy plant- Cheaper artificial energy plant- ( Often cheaper building)- Better living environment quality

Resulting benefits:- lower building running cost- Lower occupants running costs- Better quality indoor and outdoor - Environment >>Marketing stronger / higher profitspossible
