Infrastructural works outside cities, such as harbours, airports, waste dumps and dams, often provide cities with services and resources, and thus are closely linked with cities/urbanization.
Les ouvrages d &apos; infrastructure extérieurs aux villes (ports, aéroports, décharges, barrages, etc.) fournissent souvent des services et des ressources aux villes et sont donc étroitement liés aux villes et à l &apos; urbanisation.
