Will Turkey Share its Water?
I think not
Over time our country's water needs will decrease with the population fall predicted and then it will increase with the population growth. Syria's water needs will stay close to the same because it's population only increases slightly. Iraq's needs while more than double their original needs.
Water Availibility and Use
These graphs show that Turkey has a lot of renewable water originating inside the country and that they don't use nearly all of it. They only use 17% of their internal water resources.
This shows that Turkey must have a lot of agriculture given that 73.6% of their water withdrawal is for agriculture.
With the amount of of water available I believe we should give the other countries enough water to double their availablie rescources. Then we will still have the majority of the water.
