In recent years, more and more cities have been rediscovering the importance of urban greenery , also driven by the ongoing climate emergency. We are witnessing a true rethinking of urban spaces, transforming them into real ecoystems that generate a positive impact on both the environment and the people who live there.
What does urban reforestation mean?
Urban reforestation is a process in which trees, shrubs, and other forms of greenery are planted and cultivated within cities, often through true integrations with buildings and architectural design.
Why Integrate Greenery into Cities?
It’s not just about aesthetic benefits: a reforested city is certainly more beautiful, but above all it is more livable and sustainable.
This is because trees—and plants in general—play a crucial role in regulating the climate.
First of all, they absorb carbon dioxide (between 10 and 20 kg of CO₂ per year) and fine particulate matter (up to 30 kg of PM10 per hectare), while releasing oxygen —significantly improving air quality.
Trees also slow down rainwater runoff, helping to reduce soil erosion and the risk of flooding. In addition, they release moisture and absorb heat, lowering temperatures by up to 2–3 °C and contributing to thermal comfort .
Recent studies also show that living surrounded by urban greenery has significant positive effects on well-being and health. These are the benefits of biophilia, namely the innate attraction to nature and green spaces, which helps reduce stress, anxiety, and mental fatigue, while improving mood and concentration when we come into contact with plants and other natural elements.
But does reforesting cities mean giving up new buildings?
Absolutely not! Here are two examples:
- The famous Bosco Verticale in Milan hosts the equivalent of two hectares of forest. More than 800 trees, 5.000 shrubs, and 15.000 perennial plants distributed vertically.
- Aura System's breathable green walls System are an engineered system of plants and fans that enhance the natural natural biofiltration of power of plants, improving air quality in indoor spaces. The result? Healthier, fresher, and more revitalizing homes and offices—just like a small urban forest to experience every day.
