At the regular government press conference tonight (October 30), the issue of natural disasters and harm prevention and reduction is of particular concern to the press.
The Deputy Minister of Natural Resources and Environment (MONRE) Le Cong Thanh evaluated that the last natural disaster was more severe than the historical one in 1999, with 4 consecutive storms from storm No. 6 to No. 9.
Typhoon No. 9 is the strongest storm in the last 20 years, with heavy and long-lasting rains, causing more rainfall in many places than in 1999. The damage is only a small part compared to 1999, “Thanh said.
Whether or not human activities increase natural disasters, the Vice Minister of Natural Resources and Environment has analyzed more points.

According to him, geological experts assessed that the main reason is that the central region is high mountainous, strongly divided, the geology has many types of ancient, broken and cracked rocks, creating a long eroded crust. , rolled clay. This is an unfavorable condition, if it rains for a long time, the water contained in the worn layer will be opaque, creating traction, sliding down.
In civil activities, it is absolutely necessary to open roads and level to have houses and schools, including hydroelectric activities to ensure the energy security of the country. The cut of the slope, the cut of the foot of the slope are possible causes of natural disasters.
Mr. Thanh said that the occurrence of natural disasters has many different causes and further cited: “Whether forest loss is the cause or not, it is necessary to assess each specific case. In 2018, witness horrors in the areas.” The basin is a primitive forest landslide like a scratch on the mountainside ”.

The landslide incident at the Rao Trang 3 Hydroelectric Power Station was due to the construction work on the mountainside being cut off, thus this unfortunate incident occurred.
In fact, the rains and floods were much greater than in 1999, but the central provinces have operated the process between reservoirs, “cutting off” a lot of water. So only a few spots have hit a historic flood recently. Downstream, the area and depth of the flood are significantly less than in 1999.
Regarding the environmental impacts of small hydroelectric plants, experts assess specific impacts on forests, vegetation cover, biodiversity and minimum flow.
The Ministry of Natural Resources and Environment and government advisory units have eliminated 472 plans for small hydroelectric plants, in addition to 213 potential points for the construction of hydroelectric plants also need to be closely and carefully considered to ensure the development of areas. sustainable, especially in mountainous areas, avoiding natural disasters.
Favorable but adaptable
Responding further on preventing natural disasters, Vice Minister of Agriculture and Rural Development Nguyen Hoang Hiep said that the latest natural disaster in the central region was very unusual and unusual.
“Never in 20 days, the Central region has suffered 4 storms, floods, floods and storms. We know and we will warn very soon.
At the national conference on disaster prevention, the Ministry of Agriculture and Rural Development and the Ministry of Natural Resources and Environment warned that this year there will be around 5.6 storms entering the Central region, including very large storms. “We have given 15 days advance warning about the historic flooding in Quang Binh, Quang Tri, Thua Thien-Hue,” Hiep said.
The deputy minister said that he had sent many messages to the people of the central region, the political system got involved very early.
In response, according to the deputy minister, more professional forces and more synchronous teams are needed.
Mr. Hiep said that to ensure a quick and safe rescue, “he very much wishes this force has the right equipment” for all forces in the terrain and weather.
Speaking more about the recent incidents, the deputy minister said that there are 2 ships that they are still unable to contact since October 26. Currently, human damage is mainly caused by landslides.
“The landslides are very complicated and irregular. At Ranger Station 67, the last economic group number 337 in Nam Tra My district, these are long-term stable locations, not on the warning map, ”Mr. Hiep said.

According to Vice Minister Hiep, there should be more application of science and technology on alert, more than 10 provinces with high risk of natural disasters already have maps of landslides. But the erosion map has a scale of 1 / 50,000, in fact it needs a minimum scale of 1 / 10,000, at least 1 / 5,000, and to build specific points, it is necessary to map with a scale of 1/500.
Answering the question of whether or not people have impacts on natural disasters, the Vice Minister of Agriculture and Rural Development affirms that they do.
“All human activities have positive or negative impacts on all problems, including natural disasters. Our point of view is to be favorable, but favoritism for Vietnam is a controlled adaptation, not just letting it be. There must be a favor-favor solution, ”Hiep said.
Regarding disaster prevention housing construction solutions, Vice Minister of Construction Le Quang Hung said that with pipe floods, flash floods and landslides, no structural solution can be achieved. New construction sites should select locations to avoid pipeline flooding, flash flooding, and landslides. Warning maps for pipeline floods, flash floods and landslides already exist, but the scale is high and you need to scale to 1/500 to know the flood-prone location.
With construction sites, you have to select relocation points and guide people to identify geological indications, rainfall … to have relocation plans.
Tran Thuong – Thu Hang
Nghe An, the flood water rose to the roof, 2 people were washed away
Heavy rains accompanied by hydroelectric discharges flooded the districts of Nghi Loc, Thanh Chuong, Do Luong, the city of Vinh (Nghe An) submerged in water. The authorities, the army and the police have worked hard to help people escape the floods.
