The metropolitan scale of green infrastructure

Green infrastructure arises as a great source of innovative solutions to tackle many of the challenges our urban society is facing today. From better air and water quality to the control of diseases, green infrastructure has the potential to provide integrated solutions resulting in environmental, economic and social benefits.

Its strategies and approaches may include a broad scope of initiatives, such as green roofs or walls, reed-beds, urban gardens and forests, ecological corridors and others, which can be implemented in combination with zoning, mobility, housing and civic engagement plans, in order to obtain optimal results. At metropolitan scales, green infrastructure can reach the magnitude required to respond to climate change emergencies and to improve the quality of life of vast urban populations, but also face complex challenges.

This session, which is the public activity of the City Managers Days 2020, brings the perspectives of top leaders from local and regional governments on the challenges and opportunities that they face when dealing with the implementation of green infrastructure at the metropolitan scale. It will be moderated by Alexander Heichlinger, Senior Expert and Consultant in city management, who is in charge of the dynamization of all activities of the City Managers Community this year.

The event will take place online on Tuesday, November 17, from 15:00 to 16:00 CET (check your local time). 

Simultaneous interpretation will be provided (available languages: English, French and Spanish).
