In two-thirds of Mediterranean countries, air pollution levels far exceed the standards set by the European Union and the World Health Organization. The consequences are serious: from the rise in respiratory diseases to environmental degradation. But is there a natural solution to address the problem?
The Plan Bleu publication, “Nature-based Solutions in the Mediterranean: How Can Nature Help Tackle the Growing Air Pollution Crisis?”, explores the potential of green roofs, urban trees, and green and blue corridors — the so-called Nature-based Solutions (NbS) — in reducing air pollution. These strategies not only improve air quality but also offer many additional benefits, such as temperature regulation, biodiversity support, and improved public health.
This document, along with other publications and research by Plan Bleu, analyzes the potential and possibilities of applying NbS at multiple levels, from individual buildings to large-scale urban interventions, highlighting the importance of integrated approaches adapted to local contexts.
The findings highlight the need for careful design, long-term maintenance, and adequate economic investment to maximize the effectiveness of these solutions, which can contribute to greater urban resilience and sustainability, as well as to the well-being of residents.
