The Recreio green corridor project, launched in 2012 by the Municipal Secretariat for the Environment and several city departments, aims to protect and enhance the rich biodiversity and ecosystems of the area, to help with the resilience and adaptation of the west side of the city, an area affected by coastal flooding and erosion. The project mostly focused on preserving, connecting, and expanding the existing local urban nature elements and protecting their ecology. Lastly, the project also aimed to educate the residents about native vegetation and help build social interaction and cohesion between the local communities [Ref 1]. The project was designed to preserve and connect 320.76 ha of protected areas and add 60.73 ha of open public spaces and squares. And in total, the corridor has a linear extension of close to 8 kilometers, passing through very diverse urban areas (Ref. 7), including natural parks, a lagoon system, water canals, and social housing areas.

Focus

Creation of new green areas, Maintenance and management of urban nature, Ecological restoration of ecosystems, Protection of natural ecosystems

Project objectives

-Protect and enhance the local rich biodiversity, maintain the ecosystem services that help with improving the resilience of the region [Ref.1]. -Connect the natural parks of Marapendi, Chico Mendes and Prainha, including the Rangel Hill (an Inepac Designated Cultural Area) [Ref.1]. -Preserve native species of fauna and flora, as well as locally endangered species (e.g. caimans, capybaras, and the beach butterfly) (Ref. 1). -Promoting free circulation between parks[Ref.1, 2], and connect the core areas that present less human use, multifunctional streets, roads with ‘green islands’ in the middle as corridors [Ref.1]. -Expansion of the water supply and sewage collection networks, including water retention and drainage [Ref.5]. -Protect coastal areas from erosion landslides and floods [Ref.1,5]. - Create opportunities for clean mobility, with comfortable and safe bike lanes and walkways, and the enhancement of public transportation with green bus stops (Ref. 1). -The project aims to introduce an environmental education program to involve the local residents by promoting community gardening, and the program is focused on raising awareness about biodiversity and urban ecosystems [Ref.1, 5].

Implementation activities

The Recreio green corridor targeted the protection of many core areas, removed invasive species and introduced native vegetation, with a special focus on caimans and capybara caimans, capybaras, and the beach butterfly populations, at the same time allowing for people to observe these animals (with no physical contact). All core areas are protected by fences to avoid the transit of animals out of the protected areas and to limit the circulation of people in those areas. The project also expanded the quantity of green and blue infrastructures such as green "roofs and walls, multifunctional streets, collector roads with ‘green islands’ the middle as corridors of biodiversity and connectors with the urban tissue.” Additionally, the project developed and implemented educational campaigns to raise environmental awareness to educate the residents [Ref.1,4,6]. The project was multiscale as it was ranging from macro-level to micro-level -from lagoon system water catchments to local interventions (expansion of water supply and sewage collection networks, including water-retention and drainage) [Ref.5]. No new information was found regarding the progress of the project. (as fo August 28, 2021)

Climate-focused activities

Climate change adaptation:

  • Restore wetlands and/or coastal ecosystems to dissipate the effects of flooding and/or storms

  • Undertake specific measures to protect endangered species
  • Means for conservation governance
  • Raise public awareness

Biodiversity restoration:

Participatory approaches/ community involvement

  • Taskforce groups
  • Consultation (e.g. workshop, surveys, community meetings, town halls)

Details on the roles of the organisations involved in the project

The plan of the green corridor was developed by an interdepartmental study done by the City’s Environmental Department with 20 specialists from 8 city departments such as; Coordenação do Proteção Ambiental (CPA), Secretaria Municipal de Meio Ambiente (SMAC), among other municipal institutions. The municipality environmental department was responsible for the project implementation and community engagement [Ref. 1,2,3]. The Mosaico Carioca blog is an open channel of communication between Civil Society, Conservation Units, and Protected Areas located in the metropolitan area of the city of Rio de Janeiro. “The Carioca Mosaic of Protected Areas is part of a program encouraged by the MMA with a legal basis through the National System of Conservation Units (SNUC); and aims to integrate actions between the Protected Areas involved” [Ref.1,2].
