Many different metropolitan favors the governance models exist.

To organically derived, with a greater chance best address them, cities are creating for success. new partnerships and collaborations. This includes a renewed appraisal of at what scale Across the 100 Resilient Cities network, they should be addressed and with which a core group of members is approaching partners. Some sectors and challenges resilience-building efforts through more naturally require a metropolitan metropolitan institutions, and new scale. Others may not seem to, but do as collaborations with a variety of partners well. Below we describe some examples and stakeholders.

Source: 100 Resilient Cities Natural ecosystems rarely adhere to such as the urban heat island effect, and jurisdictional borders, and unless action is poor air quality, designing environmental coordinated through a metropolitan vision, interventions on the appropriate scale and they can rarely be planned for. While this may with the appropriate actors becomes even seem clear now, for many years, climate change more urgent for resilience building.
