The Recreio green corridor is an urban planning mechanism launched in 2012 by the Municipal Secretariat for the Environment in Rio de Janeiro, Brazil, alongside several city departments. The green corridor aims to protect, connect, restore and enhance the area's rich biodiversity and ecosystems as a tool to increase the resilience and adaptive capacity of the city's west side, an area affected by coastal flooding and erosion. The corridor also seeks to educate the residents about native vegetation and help build social interaction and cohesion between the local communities. The corridor was designed to preserve and connect 320 ha of existing local urban nature elements and protected areas and add 61 ha of open public spaces and squares. The corridor has a linear extension of close to eight kilometers, passing through diverse urban areas such as natural parks, a lagoon system, water canals, and social housing areas. The green corridor is part of the 'Carioca Mosaic of Protected Areas', whose legal basis is the National System of Protected Areas, and which is one of the objectives of the municipal plan to conserve and restore the Atlantic Forest of the city of Rio de Janeiro, developed by the Municipal Secretariat of the Environment in 2015.
