Newsletter «Urban soils: critical area for environmental transition» – October 2021

This month, urban soils are the guest of honour in Leonard's newsletter. Institutions and professionals are devising alternatives to the artificialization of the "critical zone", the fragile seat of chemical interactions between air, water and rocks essential to the regulation of the Earth system. More circular urban planning approaches are being developed to reuse the land extracted from building sites, while new ecological engineering activities are giving increasing importance to "brown corridors" in order to promote biodiversity.
