The “green capital” scam seems to be getting bigger and bigger as more science is established on the reality of running the city. After the CNRS which ranked Grenoble first in 2022 for the creation of heat islands due to urbanization, now Kermap has just published an indisputable cartography of nature (trees and vegetation) in large cities: Grenoble is … 27th out of the 31 intermediate cities.
Grenoble is 27th out of 31 for the share of nature in the city!
A COMPLETE MAPPINGANDTHE …
Kermap mapped the tree vegetation visible on the photographs acquired by the planes of the National Geographic Institute (IGN). The data takes into account private and public spaces, and allows a complete study of the urban green fabric to be carried out.
… WITH THE HELP OF ARTIFICIAL INTELLIGENCE
The work carried out by Kermap for Our Green Cities consisted in developing an original method of artificial intelligence to contextualize and automatically extract the vegetation from these aerial photographs. Using techniques that allow a computer program to automatically detect a tree or grassy area from a set of samples it has been taught to recognize. A successful job that puts down all the speeches of the municipality.
GRENOBLE IS BEHINDANDRE VILLEURBANNE IN BREATHING SPACES
Indeed appears the percentage of the wooded surface of the municipality, this reported to the inhabitant according to the number and even the percentage of the tree and herbaceous cover. For Grenoble, the result is overwhelming: 19% of tree cover, 21 M2 per inhabitant and 32% of tree and herbaceous surface. This puts the capital of the Alps behind a city like Villeurbanne, which Grenoble has beaten in terms of densification.
Grenoble figures compared to the national average
DAY BANDTONING UP TEMPSANDCROSS-OUTS
The link with concreting is obvious. However, trees in the city can lower the temperature by 8°. In Grenoble, a basin city, particularly sensitive to global warming, they are essential. Not only do Grenoble residents have a very low tree surface figure, but they do not have access to swimming pools as we have seen in recent days where dozens of people were refused Jean Bron, for lack of places after the closure of two swimming pools. by the municipality of Piolle (Vaucanson and Les Iris in Villeneuve). In addition, a tree can absorb up to 150 kg of CO2 per year and this weakness prohibits our city from achieving carbon neutrality in 2050. We doubt that Eric Piolle, guest of BFM this Wednesday morning July 11, will report on this data. !
LA MOITIAND GREEN SPACES ARE PRIVATEANDS: THEY WILL DISAPPEAR
Or even being asked about it. Albane Pommereau ( DL of 9/7/23) who mentioned the rendering of Kermap quoted a lot the municipal response on the planting of trees since 2014. Except that the Kermap mapping is recent and takes it into account. But the journalist notes that half of the city’s green spaces are on private land. Those that the municipality is urbanizing at a forced march and that Alain Carignon and the opposition group are asking to sanctuary in general indifference. Yet their removal would be a dangerous setback in a city so lacking in breathing space.
All the big cities have a much higher tree surface than Grenoble where it is limited to 19% of the city surface
ALL MAJOR CITIES HAVE MORE TREES THAN GRENOBLE
In the comparison of the big cities, it should be noted that all benefit from a raised surface much higher than Grenoble (Nice 33%, Montpellier 32%, Toulouse 25%, Nantes 26%…) In the recent history of our city the last large parks (the 5 hectares added to Bachelard, the 5.5 hectares of the Pompidou park), the parks and gardens (the Alliance, De Marliave, Valérien Perrin, place Lavalette, square Genin…) all have it been by the municipality of Carignon.
THE MUNICIPALITYAND PRIVILEGEANDEIG LE BANDTON
The Piolle municipality has favored concrete and it continues. Just look, after Vigny-Musset and Bonne (1.4 hectares for 1,200 new homes!), the Presqu’ile, Flaubert…
With such a record, one still wonders by what miracle Eric Piolle was able to obtain the “green capital” label from a Théodule committee judging on file. It is true that he had also wanted to compete to be crowned “best mayor in the world” by another confidential committee, before giving up, understanding the ridiculousness of the situation.
The Pompidou Park (5.5 hectares) one of the many parks and gardens created by the municipality of Carignon: it had kept the plane trees of the old barracks, unlike what was done in the barracks of Bonne….
THE DISAPPEARANCE OF EXISTING GARDENS IS PROGRAMMANDE
Whatever the swelling of the words, the elements of language of Gilles Namur, the Assistant (Greens / LFI) to the … freshness, the municipality Piolle delivers a calamitous report of the fight against heat islands, of safeguarding spaces of breathing. She continues everywhere the disappearance of private gardens as we see during the Liberation of which she wants to make a Canyon avenue, lined with high buildings, removing all the gardens. She had started in the Galtier operation by razing the garden villas.
82 and 107 Cours de la Liberation, these gardens must disappear for the municipality: private woodlots nevertheless represent 50% of the very small wooded area left to Grenoble residents to fight against heat islands
THE B STOPANDTONNAGE IS THE KEY TO THE FUTURE
As scientific data accumulates on the situation in Grenoble, it is to be hoped that the people of Grenoble will become aware. The bass drum played by the municipality on these issues has the sole purpose of camouflaging the noise of the city’s intensive concreting.
Its judgment is the key to future living together: ecologically, socially, humanly, quality of life and attractiveness of the city. For the moment only the opposition group proposes a global alternative. All the other elected officials are in the continuity of a policy that fails.
