Catalonia has been a member of one of the Urban Agenda Partnerships of the European Union, in the Sustainable Use of Land and Nature based Solutions Partnership. This Partnership has defined its focus as being to: “ensure the efficient and sustainable use of land and natural resources to help create compact, liveable and inclusive European cities for everyone”. This general focus is underpinned by two objectives agreed by the Partnership: 1) to promote a liveable compactness city model and 2) to mainstream and promote Nature-Based Solutions as a tool for building sustainable and liveable urban spaces.
A wide range of topics have been explored in the context of the Partnership, all related to the sustainable use and management of space land and other natural resources in urban development.

Being the leader of an Action, in that case the number 3, called “Identification and management of under used land and buildings”, which gave us the opportunity to join our partnership with the Circular Economy one, and elaborate a Handbook, called ” Sustainable and Circular Re-use of Spaces and Buildings”.

The first key milestones in the life of the Partnership was the production of the Orientation Paper, this process was supported by the production of Scoping Fiches, following a period of Action area scoping, the next main milestone of the Partnership was the production of its Action Plan, following the presentation of the Action Plan, the Partnership embarked upon the implementation phase. The implementation of each Action has been led by an Action Leader, along with a working group of involved Partners. The implementation of Actions progressed between meetings, supported by communication amongst the small working group and the Partnership as a whole
