The global climate change has become a problem worldwide in recent years. What must be done to prevent and reduce its side effects on cities, including Quy Nhon city, is a question that needs answering.

At the seminar on studying effects of global climate change and urban management to deal with and adapt to global climate change in Quy Nhon city, participants all agreed that Quy Nhon city’s climate has extraordinarily changed and its temperature tends to increase.
The average temperature in Quy Nhon has tended to rise gradually since 1957, according to Tran Sy Dung, director of Binh Dinh Hydrometeorology Forecast Center.
In the 1957-1984 period, the temperature reached 0.1 degree Celsius in each decade. It strongly went up from 1985 to 2004 (with 0.4 decrees Celsius in two decades).
The annual lowest temperature was up 0.4 decrees Celsius from 1965 to 1974 and 0.7 decrees Celsius in the 1985-2004 period, showing the winter has become warmer.
Quy Nhon city’s temperature is gradually increasing; meanwhile; the rainy season is changeable. Statistics showed that the difference between maximum annual rainfall and minimum annual rainfall was of 1,895 mm in the 1957-2004 period.
Also, studies proved the rainfall fluctuation in Quy Nhon city. The 1957-1965 period saw an increase, but the annual rainfall went down from 1965 to 1984. It has gone up again since 1984.
Quy Nhon has been much affected by global climate change. Many coastal areas such as Nhon Chau, Nhon Ly, Nhon Hai, and Nhon Hoi are badly affected by rain and floods, said Dam Vinh Loi, representative of Binh Dinh Steering Board for Storm and Flood Prevention and Control, Search and Rescue.
Poor households in the areas must suffer damage caused by annual disasters, but they still have to live there to earn their living, he added.
Speaking at the seminar, Le Dang Tuan, a member of Binh Dinh Construction Department, mentioned the risk of sea level rise in Quy Nhon city. It’s important to organise the living space, urban architecture, and infrastructure to deal with the risk.
He said, however, the urban planning relating to the sea level rise has been ignored so far.
The Institute of Strategy and Policy on Science and Technology studied the climate change in Quy Nhon city. This may help Quy Nhon join the project of strengthening the adaptation to the global climate change.
Vietnamese and Australian scientists came to Quy Nhon to study its adaptation to the global climate change, aiming to share experiences and work out measures to prevent and reduce side effects of global climate change on Quy Nhon city.
We decided to study the global climate change in Quy Nhon because it was a coastal city much affected by global climate change, said Dr. Tran Mai Kien, member of the Institute of Strategy and Policy on Science and Technology.
Some seminars were held in Quy Nhon in the past one month. Quy Nhon city is capable to be accepted to participate in the project of strengthening the adaptation to the global climate change, said Kien.
