The Associació MedCités / MedCities is an association of cities, with its headquarters in Barcelona, dedicated to sustainable urban development in the Mediterranean. It comprises 80 municipalities and unions of municipalities from seventeen different states and runs projects in the fields of strategic urban planning, urban services, the environment and local economic and social development, as well as training activities, technical support and the capitalisation of best practices. The network was created in 1991, since which time it has carried out dozens of projects in Mediterranean cities.

The URWAN project (Urban Regeneration and Water Management) aims to address climate change challenges in urban areas through the implementation and mainstreaming of Nature-Based Solutions (NBS). The project involves several Mediterranean cities working together to develop and implement innovative solutions for sustainable urban development and climate adaptation.

As the WP4 leader, MedCities is responsible for amplifying and mainstreaming the effects of project results and integrating economic, social, and cultural analysis of barriers to facilitate decision-makers in  mainstreaming NBS at the governance level. The objective is to engage policymakers and stakeholders in a multisectoral analysis of barriers to NBS implementation, jointly identifying measures to overcome them with input from final beneficiaries. MedCities will also disseminate the NBS Enabler Pack to amplify impact and ensure result sustainability.
