Socio-economic benefits of remote sensing technology in the study, management and control of natural disasters

Every year, 350 to 500 disasters are recorded in the world. For this reason, the study, evaluation and study of these phenomena is necessary and essential, which can be done well with the help of remote sensing technology. Using the capabilities of satellite imagery and remote sensing software, this technology provides experts with valuable information on areas affected by natural disasters.

According to the recorded reports, it can be said that the most common phenomena and events include storms and floods, which account for about 75% of the total events. Among the events that affect humans, drought, which accounts for about 5% of recorded reports, has the greatest impact (given the extent of this phenomenon and its impact on issues related to agriculture and resource management). Water) is noted.

Asia has the highest rate of such incidents per year. Examples include the droughts of 1987, 2002, and 2015, which affected some 350 million people. Due to climate change, the frequency of various events such as hurricanes as well as forest fires has increased.

Rising temperatures have also caused heat waves and bad weather conditions. Table 1 shows the benefits and applications of Earth observations in this topic. In the case of flagship crops, for example, the Copernicus system financially supports farmers in remote areas. These products can be used for underdeveloped countries where there is no other option or limited insurance options.

Copernicus helps farmers and ranchers improve their business by protecting them. Also, with the activation of the CEMS system in Copernicus, civil protection organizations and rescue teams will have access to important information that can be used for ground intervention, disaster analysis and identification of critical areas used to rescue or alter infrastructure such as bridges and roads.

This example is beyond the basic benefits and in fact in the event of events such as earthquakes, fires, storms, etc. and in order to respond, it has various social, economic and environmental benefits.

Reach the initial state of the lake

In response to the question whether this lake has reached its initial state or not, he said: the highest amount of water level of this lake in recent years is related to the late 70's and now the condition of Lake Urmia is such that it is approaching It is equal to the water level of the 70's.

He stressed: "If we have these rains continuously next year, we can see the revival of this lake.".

Mansourpour, emphasizing that the lake currently has the highest amount of water in the last 10 years, continued: In addition, the water level of the lake has recorded a 10-year record.

 

 

Rainfall status in two wet years

Regarding the rainfall situation in recent years, the Director General of Remote Sensing of the Space Agency explained: The study of satellite images shows that from January to March of last year, most of the rainfall was in the northwest and southeast of the country, but from April this year, most rainfall We had in the southern parts of the country and these rains have caused the water intake of "Jazmourian" and "Hamoon" wetlands..

Mansourpour considered the creation of lakes in the central parts of the country in the "Zavareh" region and the water intake of wetlands in the desert areas of the country as other benefits of recent rains and reminded: In general, we can say that this year was a good year for the southern parts in terms of rainfall..

 

  • The researcher in the field of remote sensing, stating that the amount of rainfall in the north and northwest of the country has been similar to the wet season, continued: In addition, we have the monitoring of dams on the agenda and our studies show that most important dams in the country 80% of their capacity is dehydrated.

He added: "With the continuation of this trend, we hope we will not have water shortages in the summer of this year, but always saving and optimal use of water consumption must be observed.".
