HCMC: Shaded walkways
The identity of HCMC is based in part on its broad tree-lined boulevards and parks such as Tao Đàn, Lê Văn Tám and Hoàng Văn Thụ, which all contribute by enhancing the quality of life in the city. At present, the city’s streets are lined with over 100,000 trees of various species and each new urban development devotes space to landscaping with trees, shrubs and other plant material.
Lyon: Green space in urban development
In Lyon, all urban development policies encourage the preservation of green spaces for the city, contributing towards a living environment of better quality. The city’s “Tree Charter” encourages greater attention to nature in urban development: protection of the tree heritage, development of a landscaping culture in urban planning and development projects, and education of citizens about the importance of trees. Today, Lyon is said to have some of the most beautiful parks of any French city, including the famous Tête d’Or, Hauteurs and Gerland parks.
