GLOBAL Water Use


Describe the proportion of water used for agriculture, domestic and industrial purposes in countries at different levels of economic development

Note water challenges and solutions in two columns. Include data and keywords.

 

Solutions

  • Recycling water

  • Micro-drip irrigation for farming reduces consumption by up to 80%

  • Desalination of salty water

  • Sensors to detect leaks in pipe systems


Challenges

  • 97.5% of water globally is salty

  • Only 0.007% water safe for drinking

  • Water consumption increasing (40% by 2060)

  • Water is finite and not evenly distributed

  • Water loss from city pipelines

  • Industry is polluting water supplies

  • Increasing disposable income in emerging economies = more meat consumption

  • Unnecessary domestic use e.g baths

WEB QUEST: COMPETITION FOR WATER IN CALIFORNIA

 

task

  1. Read the article you have been given (1 / 2 / 3 / 4)

  2. What are the causes and effects of water shortages in the article? How is water shortage leading to competition?

  3. Note the source of your information.

  4. In mixed groups, share your findings with the group.

  5. Listen to the other students in your group explaining their news articles and note information on how water shortages lead to competition.

EXTRA: Read the information on Management Strategies at the bottom of the page. Investigate management strategies in California using the links.
