Brian has a nice line above when he states - "If brown is a failure then I guess all those courses in Scotland, England, the Australian Sandbelt and Bandon are failures."
From a UK perspective, regrettably the 'green is great, brown is bad' approach applies over here as well.
Courses watered when they shouldn't necessarily be simply to make them look like the ones on TV. For 20 or so years we in the UK have been able to access full coverage of US tour golf over here via Sky and while it's nice to see it has IMO certainly furthered the 'green is great, brown is bad' approach to course preparation. Yes the so-called Augusta syndrome which has been debated on GCA often.
Obviously different parts of the globe have different needs and requirements if golf is to be played on grass. Water use certainly has it's place, but overwatering ain't good.
There have always fortunately been some enlightened courses, and some once less-enlightened have changed their methodology. Some courses accidentally 'benefit' from having no money for formal irrigation, some accidentally 'benefit' from not being able to extract too much water under their abstraction regulations. Recently 'firm and fast' golf, as highlighted by Fine Golf, has started to become more prominent - some courses even advertise their following of this approach on their websites. It's been mentioned on GCA before, but if you haven't seen it the Fine Golf website is certainly worth a look -
