| Summary: | The city of Hanoi was established within the complex hydrographic network of the Red River Delta plain, a web of rivers providing transport routes and natural boundaries. This network became more complex with its domestication: a system of dikes protecting built-up areas from river floods and the creation of many lakes and rivers to delay and evacuate rainfall runoff. These lakes play an important role technically against flood risks and culturally in determining the location of the city as well as that of many religious buildings. In addition to these two functions the lakes started to play a role as public spaces in the beginning of the 20th century with their redevelopment which was planned throughout the city. Some of them were included in the development of city parks and gardens during the colonial period and others were developed after the country’s independence. From 1992, with the intense urbanization of the capital the quality of these lakes deteriorated. If they presented obstacles, they were dried up to make way for new transport infrastructures or to enable the completion of major real estate operations. Only the main lakes in the city centre were preserved. Others smaller lakes were gradually encroached upon. Faced with contemporary challenges, however, these lakes play a remarkable role and have great potential. As ecological corridors for the city and local public spaces within a dense residential area they are essential in sustaining the infiltration of nature within the city and the conservation of uninterrupted green spaces, making it possible to fight more sustainably against the effects of urban micro-climates and heat islands. There is a need to take them into account and better integrate them within local and city-wide urban planning and development projects. |
