Visions for the Greater Hanoi 3. Growing a Structure


1. Landscape ecology explains principles of separating green from urbanization (for example in the theories of Richard Forman) – lines, patches, fields- form a mosaic of green. Between different patches (of urban and green tissue for example) exist edge conditions; patches have both positive and negative influences on another.

2. How can ecology and urbanization be combined? Could afforestation and the reinforcement of various patterns of vegetation structure the growth of a Hanoi?

3. Different principles can be implemented, such as growing forests, differentiating agriculture, creating wetlands and swampland vegetation around rivers(ladder structure), adding patches to ecological connection, adding green space to urban tissue.

4. What is the purpose of this vision? – Some benefits that can be mentioned are strong green connecting structure (ecology),. Differentiation, protection against pollutants from industry, prevention of urbanization around infrastructure. Furthermore, qualitative green spaces can be implemented in the existing city, including wetlands (for waste water treatment), a market garden, recreation.

5. Compared to the Delta scale, this proposal is about improvement of the city, preventing urbanization in one place and offering the right conditions for urbanization in another place (south of the city, between the mountains and Con River).
