BACKGROUND INFORMATION
WORLD WATER RESOURCES - FACTS
• Water covers 71% of the earth’s surface. Of this amount: 93% is in the oceans 2.5% lies in underground aquifers 2% is in ice caps 2.5% is available freshwater that we can use. • Global water consumption has risen 6 fold since 1900. • Each Australian household uses around 700L of water a day. • The UN predicts that 1/3 of the world’s population currently lives in countries already experiencing moderate to high water stress. This is measured by each country’s ratio of water consumption to water availability – its use-toresource index which gauges overall pressure on water resources. Moderate to high stress translates to consumption levels that exceed 20% of available supply. UN predicts that this figure could rise to 2/3 in the next 30 years. • Developing nations are particularly vulnerable to water scarcity as in addition to high water stress, they have little money to implement sustainable practices, technologies, or pay high water pricing schemes.

WORLD WATER RESOURCES
SUMMARY
This video provides an overview of the global geographic issue of access to fresh water. It investigates: - the social and ecological dimensions of the issue - different approaches to management of fresh water (at various scales) - conflict within and between communities - implications for social justice and equity The video includes an introductory section that provides facts about global water resources – availability, distribution and consumption. Then the video examines issues surrounding access to fresh water, through three sample studies in the Middle East, China, and Australia. The conclusion
