Urban green spaces in Mediterranean cities are under pressure from rising temperatures and fragmented planning, but a new European project is putting communities in charge of real, lasting solutions.
Urban green spaces in Mediterranean cities are under serious pressure. Climate change is raising city temperatures. Soil is degrading. And too often, parks and green areas are planned without input from the people who use them most. A Euro-Mediterranean project called Real Urban Green is working to change that by adopting a model that puts residents, local authorities, and nature at the center of every decision.
The project defines urban green spaces, or UGS, as parks, community gardens, green corridors, and any planted area within a city. These spaces do far more than look good. They clean the air, cool neighborhoods, absorb floodwater, and support mental and physical health. When they are well-designed and well-managed, they function as living infrastructure.
At the heart of the project is a participatory model, meaning one built on shared input and shared responsibility. It works in three connected phases. The first involves citizen science, where local residents assess their own green spaces. They observe, document, and report on the condition of nearby parks using structured tools. This ground-level data helps create an accurate picture of what each space needs.
The second phase focuses on co-design. Residents, city officials, and technical experts work together to shape solutions that fit the local context. This is where ideas like tiny forests, climate-smart gardens, and nature-based solutions come into play. Nature-based solutions (NBS) are approaches that use natural systems to solve urban problems. Research shows that vegetation-covered surfaces in Mediterranean urban areas exhibit temperatures close to ambient air temperature, highlighting their effective thermal regulation. A pocket forest planted in a heat-prone neighborhood can lower local temperatures, enhance biodiversity, and provide residents with a place to gather.
The third phase moves from planning to action. Communities take part in implementing the improvements themselves. This hands-on involvement creates a stronger connection between people and their green spaces, which makes long-term care more likely.

Real Urban Green is testing this model across eight pilot sites in different countries throughout the Euro-Mediterranean area. Each site has its own climate, its own urban character, and its own community needs. By working across such varied contexts, the project builds an adaptable model rather than a one-size-fits-all.
Nine partner organizations are involved in the project, and the work runs from 2025 to 2027. The model is designed to be transferable. Once tested and refined across the eight pilot areas, it will be made available to other cities and towns in the region and beyond. Improving urban green spaces in Mediterranean cities at this scale requires exactly this kind of cross-border cooperation and shared learning.
The project also invests in policy labs and capacity-building. Policy labs are structured spaces where local decision-makers work through real governance challenges together. Capacity-building equips local authorities and community groups with the knowledge and skills to keep improving their green spaces after the project ends.
One of the project’s most valuable contributions is its approach to local knowledge. Residents often know their neighborhood’s flooding patterns, shaded corners, or underused spaces better than any technical report can capture. In Mediterranean cities, citizen science approaches that involve residents in monitoring park conditions have been shown to reduce management costs and enhance the quality of nature experiences.
What does this mean in practice? A park that floods every rainy season might be redesigned with permeable surfaces and water-absorbing plantings. A bare concrete plaza might become a tiny forest. Temperature sensors at urban micro forest sites show that such interventions can reduce surrounding air temperatures by up to 2°C, creating natural cooling zones in heat-stressed neighborhoods.
Urban green spaces in Mediterranean cities cannot improve through tree planting alone. They require ongoing collaboration, sustained investment, and systems that give communities a real voice in the management of shared spaces. When those conditions are in place, green spaces stop being overlooked corners of the city and start becoming active parts of a community’s health and resilience.
The work happening across eight pilot sites today may well shape how hundreds of Mediterranean cities approach their urban green spaces tomorrow. Ultimately, the future of urban green spaces in Mediterranean cities depends on communities, planners, and policymakers choosing to work together rather than apart. That is the kind of impact that begins locally and reaches far.
