HCM CITY — Many large infrastructure projects under construction in HCM City for many years now should be upgraded to meet climate change needs, local officials say.
Climate change impacts were not factored into these projects at their inception because the weather phenomenon was a relatively unknown concept in the country then, they said.
These projects include the Sai Gon River Dyke; the East-West Highway and the Nhieu Loc – Thi Nghe Water and Environmental Hygiene.
All these projects began implementation seven years ago, while the Ministry of Agriculture and Rural Development promulgated a framework for climate change action only in 2008.
If climate change impacts over the next five to 10 years were taken into consideration when establishing the technological parameters for the Sai Gon River Dyke, the dyke would have been designed to be one metre higher than the current plan.
Similarly, the East-West Highway that connects District 1 with Binh Chanh District runs along Tau Hu Canal, has not anticipated higher tides or stronger waves that could erode the canal's banks.
"The only solution for these huge projects is upgrading," said Nguyen Xuan Hoang, deputy director of Irrigation and Flood Prevention Agency under the Department of Agriculture and Rural Development.
The height of the Sai Gon River Dyke should be increased to the level required to tackle climate change impacts, Hoang added.
Mention of the need to upgrade infrastructure project parameters comes in the wake of several recent actions taken by city authorities to prepare for climate change impacts including power-saving initiatives.
A pilot project to replace public lights with energy saving lights has been implemented in Go Vap District, under which 9,000 old light bulbs have been replaced by compact fluorescent lamps.
The fluorescent lights help save energy, money and diminish CO2 emissions, a causal factor in climate change.
The city's Department of Transport has also been planting trees along pavements, medians, and unoccupied land. — VNS
