This suggestion was put forward by many of the expert speakers at a recent high-level roundtable workshop on urban development in the city. The workshop was organized by the city’s Climate Change Coordination Office (CCCO) and by ISET, and included presentations on city plans from local government technical agencies, suggestions from international and Vietnamese experts, and review comments from representatives of national Ministries.

The half-day workshop was co-chaired by Dr Phung Tan Viet, Vice-Chair of the Da Nang City People’s Committee, and Dr Marcus Moench, Director of ISET International. The workshop was intended to provide an opportunity for discussion of how urban development plans for Da Nang might have to be adjusted to accommodate climate change.

While Da Nang is already recognized as a leader among Vietnamese cities for its investments in environmental improvement and international cooperation projects on climate change planning, city officials recognize the need to do more. Results of climate downscaling undertaken by ISET International suggested that climate change could lead to more intense extreme rainfall events in future. Da Nang already suffers from flooding, and urban development is expanding into low-lying areas adjacent to the floodplain of the Vu Gia – Thu Bon river system along the major roadways south of the city. Hydrology experts from Arup calculated that the volume of floodwater in the river system’s downstream reaches during recent flood events exceeded the capacity of the river channel by a factor of almost 20 times, so flooding was unavoidable.

Future sea level rise and more intense rainfall mean that extreme events will
