A stepping stone of Hanoi : a tri valent design proposal of urban resilient development of Van Chuong

Sammanfattning: Hanoi, is the capital of the Socialist republic of Vietnam, a developing country in Southeast Asia. Located in the Red river delta, the topography make the city threatened by flooding during the yearly monsoon. Vietnam is close to one of the five typhoon centers in the world and a forecast of climate change in this region, is intensified monsoon precipitation, storms and rising temperatures. After the implementation of the Doi Moi policy in 1986, a market economy was adopted in Vietnam. This enabled people to own land and use it freely. It also invited foreign countries and enterprises to invest in building and infrastructure projects, which made it possible to break the postwar economic isolation. Hanoi started to grow. The economic growth improved the socio-economical standard to people, boosting the urbanization. During these almost 30 years the structure of the city has dramatically changed and become a densified and sprawling city. This development has put a great pressure on infrastructure, water management and air quality. Further it has resulted in an apparent loss of green-, blue- and public space. In the context of increasing threat of climate change hazards, loss of bio diversity, increased risk of flooding and social inequalities make fostering urban resilience in Hanoi to an urgent matter. In order to gain a greater understanding of how to foster resilient urban development by green and blue measures and create public places that correspond to the local context, a design proposal of the development of Van Chuong in Dong Da district in central Hanoi was done. Green-, blue and public structures of Hanoi was analysed by using the Tri valent design theory according to Ian Thomson, as a framework. The questions “What values do green and blue structures add residents of Van Chuong?”, “How can green- and blue structures in Van Chuong be designed in order to foster urban resilience? and “Can green, blue- and public space in Van Chuong be preserved by design? are discussed. The designprocess and the choice of methodology are reflected as well, and last research questions for future interests are introduced.
