GreenInCities Barcelona: Nature-based solutions for urban renewal

Climate shelters, biodiversity and community empowerment at the Besòs river mouth. 

  • Five

    leading cities and six replicating

  • 2024-2027

    Implementation timeline

Replicability

Replicable approaches including transferable ​wildlife viewpoints, bioswales and climate shelters via inclusive co-design​, for urban green transition. 

Best suited for

The solutions put forward in Barcelona are best suited for being replicated in river mouth zones facing similar environmental and social challenges, particularly areas with high deprivation, social segregation, severe climate conditions, and limited biodiversity habitat, as these mirror the Besòs River Mouth context where interventions are designed to address both human and non-human needs simultaneously. 

Stakeholders' role

To replicate this project elsewhere, the co-design protocols for similar interventions recommend involving a multidisciplinary coalition including the local community of all ages, urban planners, architects, designers, botanists, ecologists and local decision-makers. Horizontal governance frameworks further emphasise the necessity of engaging residents, visitors, business owners and other interested populations to ensure inclusive planning and social justice​. The non-human voice should also be represented.​ 

Built-in scalable tools

The Barcelona pilot incorporates three core built-in elements that can be replicated in other urban contexts: ​wildlife viewpoints​​     ​ for wildlife and ecosystem monitoring, ​bioswales for water management and creation of new habitats​ and a naturalised climate shelter providing thermal relief and habitat during extreme weather events. These elements are designed to be modular and scalable, adaptable to various site sizes and conditions, and are directly transferable to other urban waterfronts, river mouths or degraded public spaces facing similar challenges.

Funding pathways

The GreenInCities project is funded through Horizon EU grant agreement number 101139730.
