The Deputy Minister of Natural Resources – Environment, Ministry of Agriculture, Ministry of Construction joined to answer this question at the government press conference on the night of October 30.
An issue raised in the Government’s press conference on the night of October 30 related to the central region struggling to withstand natural disasters, storms and floods is that, in addition to historical disasters, extremes, human impacts. causes (such as the loss of virgin forests, the construction of many hydroelectric plants …) what “angers” nature?
Without hydropower to cut the floods, are the consequences even more unpredictable?
Answering this question, the Deputy Minister of Natural Resources and Environment Le Cong Thanh analyzed and compared the disaster that just occurred, it was more severe than the historical year 1999 of storms and floods that happened in the central region. In 20 days, this area had to face 4 consecutive storms, of which Typhoon 9 was the strongest storm in the last 20 years. During floods and stormy days, it rained for a long time with precipitation above the historical level of 1999.
“With the drastic participation and direction of all levels, the efforts of the localities, the recently recorded damage must be said to be only a small part compared to 1999,” said Mr. Thanh.
Regarding the issue of human activities that cause the increase in natural disasters and catastrophes, especially the great loss of life due to landslides, tube floods, flash floods, said the Deputy Minister of Natural Resources and Environment, experts in the geological evaluation, the main reason leading to this phenomenon is that the central region has a highly differentiated topography, short rivers and streams and steep slopes. Regarding the geological structure, the eroded layers of the mountain are mixed with clay, absorbing the water in mud, with a great weight that generates the risk of falling, sliding down when the rain is very strong.
On the other hand, Mr. Thanh also stated that human impacts such as the felling of mountains, the felling of hills to build houses and works, including hydroelectricity, are also factors that create streaks of fine sand, causing loss of grades. natural slopes, easily lead to landslides.
These are the causes that trigger incidents and disasters, Thanh said.
Regarding the evaluation of increasing floods and landslides due to deforestation, Vice Minister Le Cong Thanh said that it is necessary to evaluate each specific case. Thanh cited, in 2016, Yen Bai witnessed terrifying landslides from primeval forests. From the rotating flycam, you can see the spots like a tiger’s claw scratching the middle of the forest.
Regarding the landslide at the Rao Trang 3 hydroelectric power station in Thua Thien Hue, Mr. Thanh said the incident occurred while cutting the mountainside to build works.
However, on the other hand, the vice minister of Natural Resources and Environment said that this year the rains and floods are higher than the historical level of 1999, but the provinces have implemented a good operation of the inter-reservoir operation, helping to cut a lot volume. downstream country. Without this intervention, the return from floods would be much higher than in 1999. Thanks to flood control and cutting works, the flood rate is lower than the risk.
Regarding the environmental impact assessment with small hydroelectric projects, Vice Minister Thanh stated that specific impact factors such as forests, vegetation cover, minimum flow should be returned to the downstream … important. Furthermore, the Forestry Law has strict regulations on forest land conversion measures for any activity and purpose, not just hydropower. Currently, several hydroelectric power plants have also raised awareness of afforestation and reforestation to ensure a sustainable water resource and limit landslides and disasters.
“The Ministry of Natural Resources has recommended eliminating more than 400 small hydroelectric projects from the plan, more than 200 potential points for the construction of hydroelectric power are also carefully and carefully considered to avoid risks of natural disasters as in the past. “- Vice Minister Le Cong Thanh warned, from now until mid and late November there will be more floods, it is necessary to respond actively.
The 15-day advance disaster warning still cannot be “executed” in time
In response to this content, Vice Minister of Agriculture and Rural Development, Nguyen Hoang Hiep, emphasized that this natural disaster, storm and flood had been identified and warned in advance.
The Government carefully and very clearly evaluates the direction, operation and alert of natural disasters. Since the beginning of January, at the National Conference on Prevention and Control of Natural Disasters, the Ministry of Agriculture and Rural Development and the Ministry of Natural Resources and Environment warned that in 2020 there will be about 5-6 storms in the Central region. including very large storms.
“We also warned 15 days before the historic flooding in Quang Binh, Quang Tri, Thua Thien – Hue,” emphasized Mr. Hiep.
The Vice Minister of Agriculture said that this natural disaster occurred in a very abnormal and abnormal way. There have never been four storms in 20 days, floods, storms, and storms.
“So in an early warning, the damage is still great, there are still scenes where people are sitting on rooftops waiting for rescue because the flood has not yet run. This is because in many places the flood area is so large that the 2-story house cannot cope, many places are flooded on the second floor. Le Thuy district, Quang Binh, has a place where rising water causes flooding at a depth of 6.3 m. The flooded area was so large that people didn’t know where to run, ”Vice Minister Nguyen Hoang Hiep reported.
In response to measures to deal with extreme rains and floods, Vice Minister of Construction Le Quang Hung said that major residential buildings continue to resist; The losses are mainly corrugated iron roofs, glass doors and walls. To cope with the flooding, he said that many localities have built flood-proof houses with a height of 10-15 m, fully capable of overcoming the historical peak of flooding. Households can store food and live safely here for many days.
However, for flash floods and landslides, the deputy construction minister said there are hardly any solutions or works to endure. Mr. Hung said the most important measure is that people do not build new ones in areas prone to flash floods and landslides.
“We have a map of flash floods, tube floods, landslides, but the scale is 1 / 20,000 to 1 / 50,000, each commune is just a small dot. The problem is how to put the 1/500 ratio into practice, ”Hung said.
