Water ban in drought-stricken Tunisia adds to growing crisis

Risk of unrest rises amid fourth dry year, poor grain harvest, weak economy and likely food subsidy cuts

Tunisia has introduced water rationing as the country suffers its fourth year of severe drought.

The state water distribution company, Sonede, has already begun cutting mains water supplies every night between 9pm and 4am. The agriculture ministry has now banned the use of water for irrigation, watering green spaces and other public areas, and for washing cars.
