The Green and Blue Axis (Eixo Verde e Azul, EVA) is an inter-municipal green corridor project connecting the municipalities of Sintra, Oeiras, and Amadora through a 15-kilometre green ecological axis along the Jamor River (Ref 2). It aims to renaturalize the river, improve water quality, and control flooding while promoting sustainable mobility through pedestrian and cycling routes (Ref 5). The project also enhances public access to green spaces and cultural heritage sites, such as the Queluz National Palace (Ref 6). EVA supports the Lisbon Metropolitan Area’s regional strategy for climate change adaptation, risk prevention, and low-carbon economy (Ref 4). Funded by the European Regional Development Fund and municipal budgets, the project has an overall investment of €11 million (Ref 1). EVA exemplifies inter-municipal cooperation, overcoming policy conflicts to achieve shared environmental, social, and economic goals, making it a model for integrated territorial development (Ref 4). The project’s long-term impact includes reduced carbon footprint and increased territorial cohesion.

Overview

Nature-based solution

  • Blue infrastructure
  • Rivers/streams/canals/estuaries
  • Parks and urban forests
  • Green corridors and green belts

Key challenges

  • Climate action for adaptation, resilience and mitigation (SDG 13)
  • Climate change adaptation
  • Green space, habitats and biodiversity (SDG 15)
  • Green space creation and/or management
  • Regeneration, land-use and urban development
  • Regulation of built environment
  • Promote natural styles of landscape design for urban development
  • Water management (SDG 6)
  • Flood protection
  • Improvements to water quality
  • Health and well-being (SDG 3)
  • Creation of opportunities for recreation

Principal problems in Functional Urban Area (FUA)

  • Climate-Related Hazards
  • River flooding
  • Environmental Degradation
  • Poor water quality
  • Land use and Socio-economic change
  • Unequal availability and access to public green spaces

Key priorities

Climate action (adaptation and/or mitigation), Biodiversity (conservation and/or restoration)

Focus

Management and improved protection of rivers and other blue areas, River rehabilitation/ restoration, Ecological restoration of ecosystems, Ecological restoration of existing green spaces, Protection of natural ecosystems, Habitat restoration

Project objectives

1. Renaturalize the Jamor River to restore its ecological function (Ref 6). 2. Improve water quality and ensure flow control to reduce flood risks (Ref 6). 3. Create green spaces that provide public access to natural environments and cultural heritage sites (Ref 4). 4. Promote sustainable mobility by developing pedestrian and cycling routes (Ref 4). 5. Reduce the metropolitan carbon footprint and support climate change adaptation (Ref 1). 6. Enhance territorial cohesion across the municipalities of Sintra, Oeiras, and Amadora (Ref 4).

Implementation activities

1. Renaturalization of the Jamor River to restore its ecological functions (Ref 5). 2. Flood control measures to prevent seasonal flooding and protect properties (Ref 6). 3. Creation of pedestrian and cycling networks along a 15-kilometre corridor (Ref 2). 4. Development of green spaces for public access and recreation (Ref 6). 5. Establishment of soft mobility infrastructure to reduce car dependency (Ref 5). 6. Cultural heritage restoration around the Queluz National Palace (Ref 3). 7. Planting of native species to enhance landscape and provide shade (Ref 6). 8. Construction of bridges and access paths to improve connectivity (Ref 6). The project mitigates flooding and environmental degradation through river restoration and flow control while promoting sustainable mobility and improving public access to green spaces. This enhances urban resilience and addresses climate adaptation goals (Ref 4).

Climate-focused activities

Climate change adaptation:

  • Restore rivers and other fresh water bodies to reduce flood or drought risk

Main beneficiaries

  • Local government/Municipality
  • Citizens or community groups

Governance

Management set-up

  • Government-led

Type of initiating organisation

  • Regional government
  • Local government/municipality

Participatory approaches/ community involvement

  • Co-planning (e.g. stakeholder workshops, focus groups, participatory mapping)
  • Deliberative decision-making processes (e.g., consensus building, deliberative polling)
  • Dissemination of information and education

Details on the roles of the organisations involved in the project

The governance of the EVA project involves the municipalities of Sintra, Oeiras, and Amadora, responsible for local implementation. Other actors involved include: - Parques de Sintra-Monte da Lua (PSML), which supports project coordination and tourism development; - National entities like the Portuguese Environment Agency and the Institute for Nature Conservation and Forests oversee environmental regulation and conservation efforts. - Other sectoral entities: the Directorate-General for Cultural Heritage, the Ministry of National Defence, the Portuguese Infrastructures, and the Portuguese Waters (Ref 4).

Project implemented in response to ...

... a national policy or strategy? Yes (The project is supported through the Portugal 2020 programme (Ref. 4).)
... a local policy or strategy? Yes ("The project is part of the regional strategy of the Lisbon Metropolitan Area (AML) within the scope of the Europe 2020 strategy objectives, namely: (i) adaptation to climate change; (ii) risk prevention and management; (iii) environmental protection; and (iv) transition to a low-carbon economy." (Ref. 4) "Furthermore, given that it applied for funding through the Portugal 2020 programme , the EVA project was also assessed by the CCDR-LVT, within the scope of the Lisbon Regional Operational Programme ( POR Lisboa 2020 ); and by the AML, within the scope of the Integrated Strategy for Territorial Development of the Lisbon Metropolitan Area ( EIDT-AML )." (Ref. 4) )
