Climate Threats
Setúbal's climate is becoming hotter and drier, a trend expected to intensify by the end of the century. By that time, Setúbal will face significant climate changes with the annual average temperature expected to rise between 1.6 °C and 3.3 °C accompanied by an increase in the number of extremely hot days (with 35 °C of maximum temperatures or higher). Experts expect an annual reduction between 5 and 17% in rainfall, with less rain throughout the year but greater intensity in short periods, increasing the risk of flash floods. Therefore, cities need to invest in more effective drainage systems and increase soil permeability by implementing nature-based solutions.
The Várzea Urban Park as a solution to Setúbal’s climate threats
Through several EU funding programmes (POSEUR – Operational Programme for Sustainability and Efficiency in the Use of Resources, PORTUGAL 2020 and ERDF – European Regional Development Fund), the City Council has already invested more than €3 million in a project that goes far beyond the initial objective of flood control using retention basins.
Another important aspect of this project is to raise environmental awareness through a tree planting programme, which involves pupils in planting activities. To enhance understanding of retention basins and the significance of the Várzea Urban Park for the local environment, the municipality organised several sessions in public schools. These sessions, conducted by municipal technicians, used a prototype to help students comprehend the hydrological processes involved.
This initiative transformed the urban green space into an environmental education hub focused on climate change adaptation. Future interventions, such as educational trails that inform and engage visitors about climate challenges and their impacts, aim to raise public awareness and highlight the importance of preserving natural resources.
Promoting biodiversity and native vegetation as part of nature-based solutions is essential for building resilient, sustainable urban ecosystems and enhancing vital ecosystem services.
An example of an ecologically based spatial planning policy is the Setúbal Municipal Master Plan, a national reference for its ecological foundation. At its core is the Municipal Ecological Structure which shapes the plan’s revision by integrating ecological values, landscape, and ecosystem services into the territorial framework.
The Várzea Urban Park embodies an ecologically driven spatial planning policy providing Setúbal’s population with an Urban Park encompassing a high-quality leisure and green space.
Project Success
The Várzea Urban Park project in Setúbal has proved innovative and successful, as an exemplary model of sustainable urbanism and climate adaptation. The climate change adaptation activities enhance Setúbal’s resilience towards associated threats and actively involve the community in actions to promote environmental education. The Várzea retention basins have recently proven their effectiveness during heavy rain events across the Lisbon Metropolitan Area, protecting the city centre of Setúbal from flooding.
The Várzea project protects Setúbal’s city centre from annual flooding, reminding that 2008 floods submerged cars in the city centre. With the Várzea intervention, the water accumulates in the retention basins and then progressively flows into the sea preventing downtown flooding.
