Barcelona trees tempering the Mediterranean city climate

A short description of the NBS project

The “Trees for living. Barcelona Tree Master Plan 2017-37” (hereafter “Tree Master Plan”), currently being drafted, will become the strategic document giving Barcelona City Council guidance for future actions in municipal planning, management and conservation of the arboreal city. With the Green Infrastructure and 1 Plan 2020 (BGIBP) - which is the “umbrella” strategic plan for actions related to green infrastructure and 1 - and the Trees Master Plan, the city has the vision to create a well-managed, healthy and biodiverse woodland aiming to: connect to both the urban and natural environment, be resilient and adapted to climate change, provide benefits to urban people and be appreciated for its value. According to the Plan vision trees are considered a fundamental part of the green infrastructure of Barcelona, a natural resource that helps enjoying a healthier life in the city. Trees conserve and increase urban 1, connect people with nature, provide social and environmental services (e.g. related to health, habitability, landscape, etc.) to current population and future generations. The conservation of this green heritage is promoted by the Barcelona City Council with the involvement of everyone, both public and private organizations and citizens.
