The countries of the Middle East and north Africa are parched

IN THE NEIGHBOURHOOD of Algiers where the presidential palace and foreign embassies are located, some think the water pressure has increased of late. But don’t tell those living in the suburbs of Algeria’s capital, where the taps have been dry for days, as temperatures and tempers rise. Protesters have blocked main roads and railways. “If the water stops flowing, so will everything else,” says a local journalist, conveying the protesters’ mindset.Algeria is not alone. In the past few months protests over water shortages have erupted in Iran, Iraq, Sudan and Yemen. Two protesters were shot dead in Iran on July 16th. And a lack of water is contributing to unrest elsewhere in the Middle East and north Africa.
