3. Oman
Expected Water Stress Level: 4.97
The water problem in Oman that ranks 3rd in our list of countries that will run out of water in 20 years has been around for a while now, but the government has failed to take any concrete steps towards tackling the issue head on. Desalination plants have been in the works since the 1980s, but indecisiveness and inefficiency have hindered their construction. As a result, the problem has intensified, and the citizens face the consequences.
