Association of Landscape Architects: "Urban reforestation against the climate crisis"

On the occasion of the National Landscape Day, which was celebrated throughout Italy on March 14, the president of Aiapp - Italian Association of Landscape Architecture Maria Cristina Tullio, stressed how this anniversary opens "a broad reflection on the role of green areas and their design in both urban and suburban areas." Interviewed by the website alternativa she highlighted how "landscape management can enable us to face the climate challenge, starting from cities".

According to the president of Aiapp it is therefore necessary to design the landscape with green areas to resist the climate crisis. "The interventions of urban reforestation can not only have the objective of planting trees - said Maria Cristina Tullio. If properly designed, putting the right trees, in the right place and the right size, the interventions allow to contain air pollution by absorbing CO2 and particulate matter (an adult tree captures up to hundreds of kg per year of CO2), lower the temperature (a single tree can decrease the summer heat from 2 to 7 degrees in the immediate vicinity, including the effect of shade), reduce noise, protect biodiversity, channel the winds, counteract geological instability, manage water. Not to mention the role of soil depollution: the roots of poplars and ash trees restore soil contaminated by heavy metals, those of willows cleanse it of organic pollutants such as hydrocarbons".

The thinking of landscape architects is therefore perfectly in line with the aims of the Veg-Gap project, and the fact that the theme of urban forestation was placed at the center of reflection on the National Landscape Day is a confirmation of its centrality.

During an Aiapp conference on urban forestry, a recent Bocconi study was presented that calculated the value of greenery in terms of food production, carbon sequestration, climate and water cycle regulation, energy savings, noise reduction, ability to attract tourism, and psychological benefits. The sum of all these items shows that a square meter of urban park is worth from 13 to 18 euros per year; a square meter of green roof from 16 to 28 euros per year; a square meter of urban orchard from 11 to 20 euros per year in terms of ecosystem services.
