Which countries are an example of economic water shortage?

. Brazil The Cantareira water system that supplies water to more than 10 million people in the Sao Paulo metro area is 75% empty. Analysts report the water may run dry in just 45 days. An abnormal high-pressure weather system over southeast Brazil is the main cause. In addition to putting million of citizens at risk, the shortage has prompted many companies to halt or move their production elsewhere.

. South Africa South Africa's government is scrambling to quench the thirst of its population. Analysts warn that the national shortage could rehash apartheid-era operations, where only certain communities had access to basic resources. A former president of the South African Institute of Civil Engineering reports that of the appoximate 230 municipalities in South Africa, 79 have no civil engineers or technicians. Only 45 have civil engineers. Water shortage poses major strains on the country's development projects.  

. Libya Libya constantly ranks as one of the most water-insecure places in the world. Breaking news reveals that the water supply for Benghazi could run dry within 30 days.
