The head of, National for Remote Sensing and Space Sciences the role of satellites in limiting climate changes in Egypt

Dr. Muhammad Zahran, head of the National Authority for Remote Sensing and Space Sciences, confirmed that the authority, with its scientific capabilities, specialized human cadres, and advanced scientific equipment, contributes to serving sustainable development, alerting to the risks of climate change and its potential effects, or limiting them, and developing proposals and solutions to avoid the consequences of these changes and adapt to them. Zahran revealed, in statements to the Middle East News Agency today, Saturday, the role of the authority’s applications and satellite images in studying the effects of climate change on Egypt in six basic areas: air health, coastal areas, tourism, water resources, agriculture, livestock and food sources, and residential communities.. The head of the authority referred to the climate station that was installed last January in the authority to receive many data from European satellites specialized in monitoring climate changes, which can cover all places in Egypt and the African continent, and provide maps of temperatures in the air and land, humidity rates, wind speed and direction, wave height, and many more.of environmental and climatic factors. Regarding the role of remote sensing techniques in monitoring air pollution rates, the head of the authority explained that by using satellite images, early warning maps are created for the areas most vulnerable to air pollution, as the increase in greenhouse gas concentrations such as CO2 - SO2 - NO2 as a result of burning fossil fuels leads to an increase in the degree of pollution.planet heat. Zahran said that by using the data of the various climatic stations, such as the authority’s station, to monitor air quality, and by processing this data, it is possible to identify the areas most exposed to air pollution and alert decision-makers to take measures that will reduce the deterioration of the environmental situation due to air pollution, which contributes to reducing the chances ofAcid rain and avoid its potential damage. He added that through digital processing of satellite data captured in the thermal infrared range, it is possible to identify the sites most exposed to light, which contributes to identifying suitable areas for the establishment of flats or solar energy production stations. He explained that through climatic data, it is also possible to identify the areas most affected by winds, and then to determine the most suitable sites for establishing wind energy farms. As for the role of remote sensing techniques and satellite images in limiting the impact of climate change on coastal areas, Dr. Mohamed Zahran, Chairman of the Authority, said that by using high-resolution satellite images captured in consecutive time periods, the rates of inundation of some low-lying areas in the northern delta and some coastal areas are monitored.Other factors, as well as increasing the rates of beach erosion and the penetration of salt water into the soil. He added that the rates of beach retreat are also being studied and calculated, and quantitative estimation of eroded areas of beaches, as well as predicting future beach lines and identifying the places most at risk of seawater intrusion therein. He revealed the role of sensor technology and satellites in studying the impact of changes on tourism rates to Egypt, explaining that acid rain, which is produced by the increase in the rates of sulfur dioxide and nitrogen dioxide gases in the atmosphere as a result of the thermal emissions of burning fossil fuels, results from an increase in their concentration and in interaction with water vapor.In the atmosphere, sulfuric and nitric acids are acids that have great corrosive properties. The head of the authority warned that if that rain falls on archaeological sites that are limestone and dolomite as the basis for their formation, this will cause erosion and distortion of those antiquities, which threatens the danger of erasing the history of civilizations. He stressed that high temperatures will also lead to the bleaching of coral reefs and thus negatively affect the beautiful natural colors, which are considered a natural wealth that tourists flock to, and the effects of increasing heat on archaeological areas and increasing suspended dust and humidity will reduce the number of tourists and the duration of their visit, thus decreasing tourism rates and increasing tourism rates.The unemployment. The Chairman of the Authority highlighted the role of remote sensing techniques in studying reducing the impact of climate change on water resources that are affected by high temperatures, as evaporation increases and rains, torrential rains and floods increase in places and decrease in others, in addition to the increase in demand for water as a result of the expansion of agricultural operations.In addition to the increase in population density at a time when the quantities of water flowing to the Nile River may decrease. Zahran explained that the risks of floods and the areas most vulnerable to damage are assessed using remote sensing techniques, geographic information systems and climate data by monitoring the water levels and levels in the Nile River through digital elevation models and topographical data on a regular basis and proposing the most appropriate paths that flood waters can be directed to in order to reduce its risks.Similar to the Toshka spillway linked to the Nile River through Lake Nasser, and to avoid problems such as those that occurred in the new urban development areas such as the Fifth Settlement. He added that solutions and proposals are presented not only to avoid risks, but also to maximize the utilization of this natural resource and the huge quantities of water, by suggesting places to build dams to reserve and store flood water for later use for the goals of sustainable development. He stressed that the authority, through satellite data, contributes to monitoring encroachments on the Nile River, such as building dams, etc., as well as estimating the size of the loss in the water budget and the risks of that, and putting decision makers before the reality of the matter. Dr. Muhammad Zahran, Chairman of the authority, stressed the role played by sensor and satellite technologies in limiting the impact of climate changes on agriculture, livestock and food sources, as agricultural crops are monitored, mapped and contrasts determined.
