It is well known that trees are a real ally for the health of our environment for a wide range of reasons, ranging from protection of the territory from phenomena such as erosion and landslides to the creation of habitats for fauna, often in danger of survival.
Planting trees has become an even more vital need in this precise historical moment, in which global warming is making its effects increasingly felt. Heat waves they occur in every corner of the planet, causing fires, devastating weather events and droughts. And putting a strain on the populations, forced to live with intolerable temperature peaks that cause health problems especially among the weakest groups, such as infants and the elderly.
Trees: solution to global warming
International studies show that trees could represent one of the most useful tools to effectively combat global warming. In fact, our green guardians possess an extraordinary ability to absorb carbon dioxide, a feature that makes them a powerful weapon against rising temperatures. In order to exploit this property, it is obviously essential to increase their presence on the entire earth's surface.
According to the calculations of the intergovernmental group of experts on climate change (IPCC), to limit the increase in the planet's temperature to 1.5 ° C by 2050, it would be necessary to plant trees for at least one billion hectares. An enormous figure but that could be achieved with a strong political will for change. Several administrations are aware of this, in a foreign land but not only. Italy is also beginning to take the first significant steps in this direction. And Milan, the nerve center par excellence of our country, proves to be ready to accept the challenge, with its project ForestMi.
ForestaMi for a green Milan
The town reforestation project signed by the municipality of Milan and designed by Stefano Boeri aims to achieve a truly ambitious goal: to plant three million new trees by 2030. The first statements on the urban forestry initiative date back to a year ago. Since that time, a team of researchers coordinated by Maria Chiara Shepherd, with the aim of drawing the most suitable guidelines to be able to achieve it. The study became an official document in the first days of August 2019.
We started with a mapping of the entire Milanese territory, counting about half a million plants in the city and another five million in the 133 municipalities of the hinterland. The three million trees that are intended to be planted over the next decade would result in a surge of more than 50 percent. Experts suggest starting with 100,000 new trees already this year. The number is expected to grow to 400,000 by 2022, continuing to 1,200,000 two years later, until the planned path is progressively completed by 2030.
Stefano Boeri, scientific director of ForestaMi, immediately identified the first urban areas from which to start with planting. Focusing on certain plots of land, removing them from any parking areas, would allow for the planting of 150,000 plants. It is also thought to reclaim the former railway yards, thus giving space to another 250 thousand thousand trees.
The main strategy will be to create a large metropolitan park. But the bulk of the planting will take place outside the city limits, in areas such as the Abbiatense, the Grugnotorto park and the land of the Ca 'Granda foundation. To achieve the goal, an important contribution will also come from private sponsorship.
In short, a shared commitment to be able to achieve an efficient metropolitan green lung, in an era when there is more need than ever.
