Reuters reports that the United Arab Emirates is abandoning agriculture and buying farms in other countries and importing all food. The UAE, which has seven percent of the world's known oil reserves, is among the top per capita consumers of water in the world. Abu Dhabi consumes 550 litres per person per day, compared to a world average of 180-200 litres. "Wars can erupt because of water," said Mohammed Khalfan al-Rumaithi, director general of the UAE's National Emergency and Crisis Management Authority. Saudi Arabia plans to rely entirely on imports by 2016 after trying to be self-sufficient for 3 years. The UAE is investing heavily in farms across the globe.
