When you visit Mo’ynaq in Uzbekistan, you can see abandoned cities taht have hundred or thousands of years old. The city had a decline in its population since the 80’s. Mo’ynaq was a port. The sea is now 150km (almost a hundred miles) away from the point at which it used to lap up against the city’s harbor. Irrigation projects by the soviets beginning in the 60’s saw the sea decline to only 10% of its original size by the middle of the first decade of the 21st century. The remnants of that are everywhere in the form of the corroded hulks of fishing ships.
