A report by Global Water Resources Group projects that by 2030, annual global fresh water needs will reach 6.9 trillion cubic metres – 64% more than currently existing reliable supply. The implications for further global and domestic conflict are obvious as interest groups vie for influence and control.
In NZ, evidence suggests that variation of rainfall from year to year and not scarcity of water is the real problem. Despite this obvious reality being easily overcome by water storage - nothing is now to be done - by Government decree. The Labour led collective (Government) decided to do away with the ineptly named “irrigation fund” in favour of other expenditure. There will be a massive future cost associated with that decision. Economists call it the opportunity cost – in this case - of fresh water.
