After climatic temperatures in Istanbul were above seasonal norms and months without rain, occupation rates at the dams decreased to the lowest level in the last 10 years. According to data from İSKİ, the occupation rate of dams in Istanbul fell to the level of 20.93 percent.
By saying that the effects of climate change are increasing, meteorological expert Prof. Dr. Orhan Sen, Turkey has 700 thousand cubic meters of water per capita annually, the amount of water per capita is now starting to decrease to less than a thousand meters cubic and 700 cubic meters, he warned that in 2030 it will fall.
In Turkey’s water-scarce countries in 2030, Sen said there would be a minimum 60 percent occupancy rate for dams coming into the summer, adding that the need to reach fullness.
“LET’S GO TOWARDS TWO SEASONAL WEATHER”
Prof. Dr. Orhan Şen spoke as follows:
* Global warming has an effect on the climate. Causes climate change. The effects of climate change have begun to be seen more in the region in which we find ourselves. The increase in natural disasters has also begun to manifest itself. Increasing 1 degree increases natural disasters by 30 percent. The average temperature rise in the world has now exceeded 1 degree. If the temperature rise reaches 4 degrees, that is a very significant increase. Then Turkey will enter the tropics. Even in such a situation, we are now heading towards a semi-arid climate.
* We are now out of 4 seasons. Fall and spring, which are the transitional seasons, were also shortened to one month each. This is because we leave the Mediterranean climate and move on to the semi-arid climate. We are heading towards a two season climate. Summers will be hot and dry, winters will be hot and rainy.
“THE THIRD DROUGHT AWAITS US”
* In 1900, the world population was one billion, now it has grown to 8 billion. The water began to be scarce. Turkey’s annual amount of water per person was 700 thousand cubic meters. Now it has started to drop below 1,000 cubic meters. We weren’t rich in water at the time, but our water was enough for us. Now we have started to become a water poor country. In 2030, it will decrease to 700 cubic meters, then we will be poor in water. Recently, due to climate change, we see a decrease in rainfall in Turkey.
* If it rains a little somewhere in the world, it rains a lot in one place. We divide the drought into three. The first is due to meteorological drought and low rainfall. It began to show its effects since January of last year. After that, we move towards hydrological drought. What this is is that the water is reduced in rivers and lakes. We started to see this type of drought as well. Like the occupation rate of the dams in Istanbul dropping to 20 percent.
* After that, a third drought awaits us. A more insidious drought, which is agricultural drought. Agricultural drought will cause low yields. We will see the effects of this in the spring, during the harvest season. Socio-economic problems are related to agricultural drought.
“THE RISK IS TOO HIGH”
* We have to think about this in agriculture now. We must bet on agricultural products that do not require water. How much rain will it rain in January, February and March. Models do not show that it will rain too much. In this case, we will remain in a position to manage the current situation. We need to get in early in the summer with a 60 percent occupancy rate so we can be comfortable. The decrease in winter rainfall shows the effects of summer. It means that we will install headphones in the summer of that year. That is why we are in a situation where the risk is very high right now. Action had to be taken in midsummer. (İHA)
