Pre­cious re­source is world’s is­sue

Weekend Argus (Saturday Edition) - - PROPERTY -

OP­ER­A­TIONAL im­prove­ments have been adopted most widely in the Western Cape. There is an in­cor­rect per­cep­tion that the wa­ter cri­sis is re­stricted to spe­cific re­gions. In re­al­ity, wa­ter se­cu­rity is a na­tional and in­ter­na­tional is­sue.

Ac­cord­ing to the US Ge­o­log­i­cal Sur­vey, more than 99.7% of the earth’s wa­ter is un­us­able by hu­mans and most other liv­ing things, ei­ther be­cause it is saline or trapped in glaciers. This leaves a tiny por­tion of ac­ces­si­ble fresh wa­ter for us to use.

Add to this the fact that the world’s pop­u­la­tion has ex­ploded, and will con­tinue to do so. The World Wa­ter Coun­cil re­ports that the hu­man pop­u­la­tion is on track to grow by 40% to 50% within the next 50 years.

This means that ev­ery year, com­pe­ti­tion for a clean sup­ply of potable wa­ter for sus­tain­ing life in­ten­si­fies – so much so, some ex­perts be­lieve, that the next world war will be fought over wa­ter.
