The Tagus Estuary Linear Riverside Park is a significant environmental and recreational project in Vila Franca de Xira. As part of a broader urban regeneration initiative, the park aimed to enhance the natural and cultural landscape by promoting ecological regeneration while providing public access to the Tagus River (Ref 1). Created in 2013, the park has won several international awards and since then, the park has undergone several extensions. In 2017, another 700-meter walkway was added towards Santa Iria, and the inhabitants of this urban area of Vila Franca de Xira widely use it (Ref. 6). The park covers over 14 hectares and includes pedestrian and cycling paths, environmental education facilities such as the Bird Observatory, and the Environmental and Landscape Interpretation Centre (Ref 2). Recently announced in 2023, the park's newest expansion is set to extend the riverside trails further, creating a continuous route from Lisbon to Alhandra (Ref 5). With future phases planned, the project is expected to significantly increase public interaction with the riverfront and its biodiversity (Ref 5). In this new project phase, the Vila Franca de Xira Municipal Council begins the requalification and environmental and landscape conservation of another section of the riverfront of the Municipality of Vila Franca de Xira, between Alverca and Sobralinho, covering an extension of approximately 4.9 km and an area of ​​approximately 14.1 hectares (Ref. 7). The extension of the park will be developed similarly to its existing infrastructure. New paths for pedestrians and cyclists will be created using elevated wooden structures (walkways). In total, two new cycle-pedestrian trails will be created – Trilho das Comportas (3.32 kilometres long) and the Trilho dos Salgados (594 metres long) –, and the Trilho do Tejo will be extended by a further 990 metres (Ref. 5).

Overview

Nature-based solution

  • Parks and urban forests
  • Large urban parks or forests

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
  • Habitat and biodiversity restoration
  • Water management (SDG 6)
  • Flood protection
  • Health and well-being (SDG 3)
  • Creation of opportunities for recreation
  • Enabling opportunities for physical activity
  • Social justice, cohesion and equity (SDG 10)
  • Environmental education

Principal problems in Functional Urban Area (FUA)

  • Environmental Degradation
  • Biodiversity loss
  • Land use and Socio-economic change
  • Unequal availability and access to public green spaces

Key priorities

Climate action (adaptation and/or mitigation)

Focus

Maintenance and management of urban nature, Maintenance or upgrade of exisiting green spaces (e.g. parks)

Project objectives

1. Restore and enhance the natural habitats and biodiversity of the Tagus Estuary, addressing environmental degradation (Ref 1, 7). 2. Improve access to the riverfront by creating continuous pedestrian and cycling paths, enhancing public enjoyment of natural spaces (Ref 5). 3. Increase resilience to climate-related issues, such as flooding and heat stress, through green infrastructure and native species planting (Ref 1, Ref 3). 4. Provide spaces for leisure, environmental education, and community engagement through facilities like the Environmental and Landscape Interpretation Centre and Bird Observatory (Ref 1, Ref 2). 5. Promote sustainable urban regeneration by integrating natural and built environments harmoniously (Ref 1). 6. Promote Nature Tourism by boosting the range of activities on offer in the Tagus Estuary (Ref. 7). 7. Implement measures to minimize the impact of rising sea levels as a result of climate change (Ref. 7). 8. Build access infrastructures and promote activities on the river through a diverse range of spaces (Ref. 7).

Implementation activities

1. Ecological Restoration: Planting native species to enhance biodiversity and support habitat restoration (Ref 1, Ref 5). 2. Construction of Pedestrian and Cycle Paths: Creating over 6 km of trails to improve accessibility and connectivity along the riverfront (Ref 1, Ref 5). 3. Development of Educational and Recreational Facilities: Building the Environmental and Landscape Interpretation Centre, Bird Observatory, and multifunctional spaces for public engagement (Ref 1, Ref 3). 4. Expansion of Riverside Acces*: Extending the park by 4.9 km and building new trails, including elevated wooden walkways to enhance public access to nature (Ref 5). 5. Infrastructure for Climate Resilience: Integrating green infrastructure, such as renaturalized areas and flood-resilient design elements (Ref 1, Ref 3). The NBS addresses ecological degradation by restoring natural habitats, improving biodiversity, and enhancing public accessibility through continuous trails. Additionally, it tackles climate resilience by implementing nature-based infrastructure, helping mitigate flooding risks and heat stress, while promoting sustainable interaction between urban spaces and nature (Ref 1, Ref 3, Ref 5).

Climate-focused activities

Climate change adaptation:

  • Increase urban vegetation cover to reduce urban heat island effect
  • Protect and restore coastal ecosystems, to address loss of land and livelihoods, due to rising sea levels

Biodiversity conservation or restoration-focused activities

Biodiversity restoration:

  • Restore species (native, endangered, or unspecified)
  • Restore native species

Main beneficiaries

  • Citizens or community groups

Governance

Management set-up
