                          THE WORLD'S WATER CRISIS


For Teachers
Brief Summary of Program
This program looks at the predicament facing the world’s fresh water supply. A rundown is given of
how much fresh water is on the Earth, how much is locked in polar ice caps, and how much is readily
available now, with Australia’s situation placed in context with that of some poorer parts of the world,
whose people face a drastic lack of access to fresh water supplies. The quantity of water needed to
manufacture a selection of everyday products is examined, to provide an appreciation of the total
quantities of fresh water used in our country, outside of the home. The need to conserve water on any
scale in agricultural, industrial and domestic use is emphasised – with case studies including VISY
chairman, Richard Pratt’s vision to pipe all irrigation water; drip irrigation at Tandou Farm in NSW;
and a high-tech water-saving urban housing development in Melbourne.
Finally, a range of water conserving ideas to implement around the home are presented, taking the view
that one person makes a little difference, but everyone together makes a huge difference.
This program features some excerpts from the ABC’s ‘Landline’ and ‘Dimensions’.


Further Points for Consideration
One of the aims of this program is to give students some sort of appreciation of water use in the
national and global contexts, and linking that with the difference an individual can make in saving
water, which ultimately contributes to solving a much bigger problem.
Some of the suggested activities before and after the program focus in on the individual student’s use
of water, and that of his or her household. One also involves contacting the local water authority with a
view to learning a little more about what it does.
The video touches on various points about the use and need to conserve the most precious of all
resources. It is particularly suitable for introducing a water topic.

Some Useful Websites
*At the time of printing these Teacher Notes, these websites were found, after a number of separate
visits, to be both accessible and appropriate for the subject material. Teachers are advised to
thoroughly check any website listed here before passing its details on to students.

www.dlwc.nsw.gov.au website of the NSW Department of Land and Water Conservation. A wide
range of interesting information about resource management. Click on ‘Caring for our Natural
Resources’ on the home page, and then on ‘Water’ from the list down the left hand side. Also click on
‘What’s New’ on the home page, and then on ‘Rural Water Management’, where updates on the quality
of water in regions can be checked.

www.wolfweb.com.au/water/wetlinks well worth a visit – a great range of links to a variety of water-
related authorities, conservation organisations, projects – including those of schools, links to other
related sites, even an animation of the 1998 PNG tsunami.

www.wsaa.asn.au/ratings/ratingsabout information about the water conservation ratings given to
household fittings.

http://www.acfonline.org.au the Australian Conservation Foundation’s website. Click on ‘Rivers and
Water’ under ‘Topics’ on the left hand side of the home page for an extensive list of river and water
quality related issues.

http://www.nccnsw.org.au the Nature Conservation Council of NSW website. Click on ‘Water’ across
the upper part of the home page.

http://www.brisbane.qld.gov.au/home_garden/water_sewerage/water_conservation/more_waterwise/in
dex.shtml
Both are pages on the Brisbane City Council’s website, dealing with sensible water use around the
home.

http://www.waterwiser.org/template2.cfm?page1=intllinks&page2=links_menu worth the time putting
in the address! A page with links to a range of Australian and international water conservation sites.
The Australian ones are mostly Victorian water supply companies. Some interesting international
perspectives from various parts of the world including the Middle East, Britain, Singapore, India, New
Zealand, Canada, and Africa. Also an extensive list of links to related topics.

Suggested Activities After Viewing the Program

1.   Design a poster or series of posters to inform people about the four Dublin Water Principles.

2.   You are responsible for drawing up a list of water restrictions for times of drought in your area.
     List at least five restrictions you would bring into force.

3.   From your list in No. 2 above, identify any restrictions you would consider making permanent. In
     each case, think of a water-saving alternative people could use – ie don’t just tell them what they
     can’t do, suggest what they can do instead.

4.   Contact the authority responsible for your area’s local water supply. Collect any printed
     information they have about managing the water supply, and ways in which people can conserve
     water.

5.   With the help of an atlas, identify countries in the world that experience low rainfall. List at least
     half a dozen, then choose one and find out other information about it – its population; standard of
     living; main industries or products. Do you think the country you have chosen has been able to
     overcome its lack of natural water supply? Explain your answer. Find out anything you can about
     whether a lack of water is an on-going serious problem for the people of this country.
