(Focus on Boao) China launches national natural disaster risk survey and plans to build an integrated air-space-earth disaster monitoring system
China News Service, Boao, April 20 (Reporter Wang Xiaobin) The Boao Forum for Asia 2021 Annual Conference held a sub-forum on "Disaster Management and Sustainable Development" on the 20th.
The reporter learned from the meeting that China has already initiated the investigation of natural disaster risks and plans to establish an integrated air-space-ground disaster monitoring system.
The Asia-Pacific region is the most vulnerable region to natural disasters in the world. According to the results provided by the World Disaster Assessment Report, the frequency of disasters, deaths, and economic losses in this region account for more than 40% of the entire world.
Among them, China has fewer volcanic disasters, and other types of natural disasters have occurred in recent years.
"In 2020, China will not only have severe epidemics, but also serious disasters. The floods are the most serious floods since the 1998 flood." Shang Yong, vice minister of emergency management of China, said that China has gone all out to fight and rescue disasters and protect them to the utmost extent. The safety of people's lives and property.
Last year, the number of deaths due to natural disasters in China was the lowest since the founding of New China, "but the difficulties we face are more worthy of attention than the achievements we have achieved."
Shang Yong revealed that the Ministry of Emergency Management intends to establish an integrated air-space-ground disaster monitoring system. "From the sky, China will develop the Skynet emergency satellite system in the next step, including multiple dedicated monitoring satellites." These satellites can cooperate with the existing high scores. Satellites help disaster prevention and mitigation work in the “Belt and Road” region; various early warning sensors are deployed in cities and villages on the ground to form this system.
Shang Yong believes that technology can play a big role in this. For example, artificial intelligence technology can help study and judge disasters, and technologies such as satellite communication and microwave communication can ensure the normal operation of the rescue command system when power is cut off.
It is generally believed that the essence of risk and disaster is information asymmetry.
To solve this asymmetry, a national natural disaster risk survey led by Shi Peijun, a professor at Beijing Normal University and president of Qinghai Normal University, is underway.
"We want to thoroughly understand the risk of natural disasters on the entire land of China." Shi Peijun said, "We use towns and villages as the basic unit to investigate 20 major natural disaster carriers, including roads and houses. After uploading such a few sets of data surveys We only know where the risks are.” Shi Peijun said, just like China’s epidemic prevention and control work, “knowing disaster-related information early can enable early reporting and early treatment”.
