In order to cope with the climate crisis in urban areas, the city of Paris is seeking to make the city greener by creating "urban forests", an ambitious project that everyone does not believe in fashion.
The strategy promoted by Mayor Anne Hidalgo will create parks and gardens in order to reduce the overall temperature.
Hidalgo plans 30 hectares of green space and creates a plantation of 20,000 new trees by 2020.
The first phase of the urban forest will open at the end of the summer. It will be located on an unused train line to create a green belt in the city, similar to High Line Park, a stretch of greenery with trails in Manhattan, New York. was built in 2009.
Students will have something to look forward to next fall with 28 different clbades on gardening.
According to the Parisian Vice-Urbanist Jean-Louis Missika, four urban forests should open during the year 2020.
Hot in the city
According to a study carried out by the University of Zurich on 520 major cities of the world, by 2050, the urban agglomerations located in temperate regions will experience a climate change equivalent to their displacement to 1000 kilometers in the south. Temperature increases range from 3.5 ° C to over 4.7 ° C.
This summer, the town hall announced that the temperature of the rue du Louvre, in the center of Paris, reached 65 ° C.
The city can create microclimates by reducing soil temperature because it is this reflected heat that amplifies the effect of heat, according to Vincent Viguié, a scientist at the International Center for Research on the Environment and Environment. development, based in Paris.
Concrete ideas include the creation of shelters in the city by planting trees behind the Opera Garnier, as well as grbad on one of the two banks of the Seine.
Although a number of projects are currently in the planning or planning stages, the Mayor's Office has not published a schedule or budget for urban forests.
For the mayor of Paris candidate, Pierre-Yves Bournazel, candidate for the post of prime minister of the city in 2020, urban forests "do not exist". "These are just ads," he added.
But researcher Viguié believes that planting vegetation can lower temperatures. The greenery creates shade and refreshes the air around it when it is watered: the water evaporates, creating a cooler environment.
The idea of replacing paved areas with a more natural surface, such as greenery for example, could reduce heat because the green color of plants and trees absorbs less heat than black asphalt, declared Viguié.
