The heatwaves of the last few summers have been the trigger for massive tree planting projects and the creation of urban forests, notably on the Miyawaki model, with the urban tree being promoted to the rank of saviour of cities, at least the one without which they will soon be unlivable in view of climate change.
The Conservation, an online media and non-profit association whose objective is to share knowledge by bringing the voice of researchers into the citizen debate, offers several articles on this subject that shed light on current events with reliable expertise based on academic research.
Professor Serge Muller, researcher at the Institute of Systematics, Evolution and Biodiversity of the National Museum of Natural History (MNHN), offers a reasoned analysis of the creation of these "Miyawaki microforests", which complements a previous article by INRAE researchers entitled "Miyawaki method: why are "microforests" not really forests? "
If the debate is not closed on the contributions of this method, these articles clearly raise the question of the place of the tree in the city, which it is not enough to plant but which it is necessary to ensure that it will grow in the best conditions.
We invite you to watch the presentations by Caroline Mollie, author of l'Urbanisme Végétal published by Actes Sud, and Luc Vinai in the "MOOC Nature en ville parcours perfectionnement".
