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.
