Sure I was a little skeptical when I first caught wind of this series (links to the remainder of the series at this link), but it's actually pretty good. Obviously it's not real in depth or tackling hard-hitting issues, but it does give a nice overview of how golf courses are trying to remain in operation during prolonged droughts affecting the southwest and southeast US - areas with major golf infrastructure as part of their economies.
They include discussions of how high tech golf courses are getting in managing their irrigation systems, research on new strains of grass that can be grown with low quality water in poor soils, even a trend toward painting courses green in winter rather than overseeding to keep green grass year round.
There are lots of people who dislike golf courses and their apparently profligate water use. I'm not a big fan myself. But the truth is, golf courses tend to make very efficient use of water because it is one of their most significant costs. They are also a pretty good use of water economically - what they contribute to local economies per unit of water used is pretty high among large water users. Also, they are often under political and regulatory pressure to conserve if they want to remain in business. And they are businesses - and saving water saves money.
Here in Arizona, most golf courses in the larger cities use effluent for irrigation - both because they have no other choice and because the effluent is often subsidized (as an enticement to get them to switch from groundwater). I'm pretty sure the only way to get a new golf course approved within an Active Management Area is by committing to effluent use for irrigation.
Even outside the AMAs, where use of groundwater is subject to very little regulation, the Arizona Corporation Commission has been trying to insist that new development not include golf courses until the development is large enough to provide sufficient effluent to water the course. It didn't work on the recent Pravada development near Kingman, which I previously posted on. But there are several new members on the Commission this year which may breathe some life into that policy.
