Water Systems
What is the current situation of the greater Hanoi region? What are the problems?1. Infrastructure and industry. Hanoi has historically been connected to surrounding settlements through a system of rivers and roads. This network has changed towards a land based network, starting with the making of bridges over the river, and followed by different impositions during colonization, war, communism and Doi moi Era.
2. Forests ( in the mountains), agriculture (almost monoculture - rice fields) and recreation (national parks and golf courses). The policies of reforestation currently affect the less fertile lands uphill and, at the same time, lead to the collapse of collective agricultural systems.
3. Water household. The Red River has flooding problems. Once connected to the Red River hydraulic system, many secondary rivers have become cut off by dams and gates, reducing their use to solely rainfall drainage. They are ‘dead’ rivers, because the rhythm of rising and receding of the water has disappeared, and due to the elevated pollution levels. Their dams and gates controlling malfunction (they are not being opened during floods).
4. Disappearance of lakes in the city of Hanoi. The city’s remaining lakes are used for different purposes. There are the old, cultural lakes in the city, as well as waste water treatment lakes and lakes as a backbone for residential areas constructed on the edge of urbanization. Lakes outside of the city have recreational purposes (golf courses on the shores).
