1. "Environmental concerns over
the use of land for golf courses have grown over the past fifty years.
Specific issues include the amount of water required for irrigation and the
use of chemical pesticides and fertilizers in maintenance, as well as the
destruction of wetlands and other environmentally important areas during
construction. The United Nations estimates that, worldwide, golf courses
consume about 2.5 billion gallons/9.5 billion litres of water per day. Many
golf courses are now irrigated with non-potable water and rainwater."

2. Australia has the third highest
number of golf courses per capita in the world (behind Scotland and New
Zealand). We have 1530 clubs (2015) nationally according to the
Australian Golf Industry
Council.
3. Calculate the number of litres of
water per day consumed by the total of Australian golf courses.

Is this ethical to
use so much water in the driest continent on Earth? Why? Why not?

1. Read the following
article:
The RAGC Stormwater Project brings significant benefit to the community and
great benefit to the golf club.
The Problem.
Achieving a sustainable supply of irrigation water for the golf course.
South Australia is known as the driest State in the driest continent on
earth and golf courses need a large supply of irrigation water to survive.
Royal Adelaide Golf Club has traditionally had access to unlimited free
underground water for its irrigation needs. The course currently
uses in excess of 200 megalitres of bore water from the aquifer (200 metres
below the surface) each year, most of it over the four or five dry months of
summer. [Editor - highlight]
The Government of South Australia is in the process of regulating and
restricting access to this water and will inevitably charge users for its
consumption.
The club wished to secure its future supply of water if at all possible.
The Solution.
With the close cooperation of the Government of South Australia, the club
has developed within its boundaries a wetland to harvest stormwater runoff
from the surrounding suburbs. The stormwater is cleaned by the reedbeds in
the wetland sufficiently to be injected back into the underground aquifer.
The club should be able to put as much water back into the wetlands over
winter as it takes out over summer, becoming a net zero user of aquifer
water.
Funding.
The total cost of this project was some $A2.7 m, which was shared equally
between the club, the Australian, and South Australian Governments. The
total project of some $A8.0 m. included similar wetlands and aquifer
recharge systems at The Grange and Glenelg Golf Clubs nearby.
Benefits to the community.
Adelaide has a problem with the discharge of turbid stormwater into the
ocean which restricts sunlight to the native sea grasses and kills them. The
wetland schemes significantly reduce the flow of stormwater into the ocean.
A further benefit is that a large user of underground water can reduce its
usage to zero and in fact could become a net provider of water. This is
significant as aquifer water levels are dropping and salt levels are rising
over time.
Benefits to the Club.
The aquifer water contains salt at 950 parts per million. Use of this water
causes a salt build up in the bent greens, which can cause bare patches by
the end of summer. The cleaned stormwater contains salt at approximately 100
parts per million, which is lower than AdelaideĀ“s potable water supply. Use
of this water will eliminate the salt build up problem.
The wetland has greatly enhanced the appearance of an area of the course
that grew only scrubby vegetation in salty soil.
The Result.
The Royal Adelaide Golf Club has just begun to inject cleaned stormwater
down into the aquifer. The project brings significant benefit to the
community and great benefit to the golf club."
2. Using the following diagram,
summarise each step:
3. If the cost of water is $0.0872 per
kilolitre (source:
City West Water charges), and
the club uses 200 megalitres/year, how long will it take for this Project to
start saving the club money (after the recovery of the $A2.7M)? 1
megalitre=1000 kilolitres. How much money would the golf club save per year?
4.
Is this a solution you would promote
to other Australian Golf Clubs as an Sustainable Solution? Why? Why not?

1. You are to create an informative online
pamphlet to be given out at a Greenkeepers' conference, informing
Greenkeepers on the lastest information to improve their golf-courses and other areas by ...
a. Get in touch with a local golf club or
using online resources (provided) -
describe the optimum grass lengths of the main areas on a golf
course.
b. What equipment is needed to maintain
golf courses? Why are they needed?
c. What seed/ grass runner is most
commonly used and why?
d. What are the most reputable
fertilisers?
e. What other places require greenkeepers
and how do their requirements, equipment and resources differ from
golf courses?
2. Using the following
article as inspiration:
a. How would you improve the irrigation and
maintenance of your local golf course to make it more eco-friendly?
What costs could you save each year for the club? Which initiatives
would you use: Worm farm? Reduction in chemical fertilisers? An
orchard?
b. Write an article describing your proposal and
success at your current (imaginary) golf course and the possible
implications for other golf courses.
c. Publish your work with password protection
using Jimdo
3. Gather the information that you have found and
collate it in an online poster using
