The canton of Geneva is aiming for a tree canopy<\/strong> cover of 30% by 2070. Tree canopy is the area covered by the tops of trees. It helps cool the city during heatwaves. Researchers from the American university Harvard spent two years studying tree planting in Greater Geneva.<\/p>\n The Graduate School of Design<\/strong> of Harvard presented its study on urban forests in Geneva at the Rendez-vous de l\u2019urbanisme. The presentation took place in the new auditorium of Pictet<\/strong>. The project was made possible by the La Gara Foundation, chaired by R\u00e9my Best.<\/p>\n According to L\u00e9man Bleu, the canton\u2019s tree cover stands at about 22 %<\/strong>. But it remains very uneven between neighbourhoods. Between 2013 and 2023, it grew by only one per cent. The researchers propose a \u201cforest mosaic\u201d: a network of forests across the territory. They compare trees to infrastructure, like water or electricity. They also recommend diversifying species, as some maples could suffer from rising temperatures.<\/p>\n The study relies on the \u201c3-30-300\u201d rule. Every resident should see three trees from their home, live in surroundings with 30% tree cover and live less than 300 metres from a park.<\/p>\nThe key points<\/h3>\n
