The Metropolitan Region of Campinas has engaged with decentralized management, developed policies and actions in order to consolidate a proposal for the Connectivity Area, a buffer zone that prioritizes corridors of integration for the Metropolitan Region and identifies sites providing Ecosystem Services (ES). Supported and facilitated by ICLEI South America through the INTERACT-Bio project and in close collaboration with the RECONECTA-RMC program, the initiative resulted in decisions and alignments, capacity building, articulation of the twenty cities of the region and other stakeholders. The Connectivity Area proposal has been integrated to relevant regional planning policies as a strategic area for metropolitan action. A Local Biodiversity Strategy and Action Plan was developed and will further identify roles and responsibilities for action within five main pillars: urban afforestation; linear parks; ecological corridors; local wild fauna; inspection, compensation and regulation; communication and articulation.
