VietNamNet Bridge - By 2070, there will be nearly 10,000
hectares, 257,000 people, 1,494 km of roads and many production facilities,
industrial parks being flooded due to high tides and the sea level rise,
according to a workshop assessing the risk of climate change on human health in
HCM City on November 13.
At this workshop, experts said
that climate change has made the appearance of diseases affecting human health.
They also demonstrated that climate change affects flooding, especially in big
cities like Ho Chi Minh City.
In particular, Mr. Bui Chi Nam,
from the Southern Institute of Hydrometeorology and Environment showed a
flooding script in Ho Chi Minh City to 2070 (excluding the impact of rain).
Nam said that flooding in Ho Chi
Minh City is caused by many effects, including rain, high tides plus the rise
of upstream water. Skipping the rain factor, only high tides and the sea level
rise have affected the city's flooding.
He said that by 2070, there will
be nearly 10,000 hectares in the city to be flooded, especially in the
districts of Can Gio, Nha Be, Binh Chanh, Thu Duc and District 12.
Based on research data, Nam
proved that by 2070, flooding caused by high tides and sea level rise under the
impact of climate change will seriously affect land use planning, water
resources, infrastructure, manufacturing facilities, industrial areas and
people in HCM City.
Specifically, if in 2020 when the
sea level rises by 8cm, Can Gio District will have 546 hectares being flooded
but in 2070 when the sea level rises by 37cm, the flooded area in this suburban
district will increase to 1,565 ha (2.1% of the total area of the district). In
particular, according to the calculations of the Institute, Binh Chanh will be
the most flooded district with 17.59% of the total area (about 4,447 ha in
2070), followed by District 12, Thu Duc, District 2 and Binh Tan District.
According to Nam, flooding will
also affect the traffic system. "By 2020, there will be about 949 km of
roads in the city being flooded. By 2070 it will increase to 1,494 km of
roads," Nam added. Currently, HCM City has 3,897 roads with a total length
of 3,534 km.
The city’s industrial and
manufacturing facilities will also be flooded by 2070, such as Le Minh Xuan
Industrial Park with 34.37% of the total area, Phong Phu Industrial Park with
29.11% of the total area and the High-tech Park in District 9 with 1.65% of the
total area.
Nam confirmed that there will be
about 257,000 people affected by flooding, with Binh Chanh District (68,808),
District 12 (62,687), Thu Duc district (34,818 people) and Binh Tan District
are most severely affected.
"To cope with climate
change, Ho Chi Minh City needs to develop a coordination mechanism and a more
effective action plan," Nam suggested.
Earlier, at a meeting of the Ho
Chi Minh City People's Committee, the Department of Natural Resources and
Environment proposed the city to allocate VND26 trillion ($1.24 billion) to
develop plans to respond to climate change by 2015.
Specifically, the money will be
pumped into projects related to urban planning, water resources, energy,
agriculture, waste and raising people’s awareness of climate change.
