New Zealand is, as Geoffrey Palmer once noted, a very pluvial country.
We are blessed with a bountiful supply of water and contrary to the doom merchants who think we don’t have enough, all but 2% of it flows from its source to the sea.
IrrigationNZ used World Water Day, yesterday, to put water use in perspective:

The next biggest user is irrigation. Worldwide irrigation grows 40% of the world’s food on 20% of the world’s agricultural land, and here in New Zealand irrigation also plays an important role in food production.
New Zealand is very fortunate to have plentiful supplies of freshwater when compared with other countries worldwide.
