Pacheco-Vega Keynote WaterDop Pacheco-Vega Keynote WaterDop Presentation Transcript

  • New tools for old problems: Water footprint, water stress and virtual water (Canada and worldwide) Presented by Raul Pacheco-Vega, PhD http://www.raulpacheco.org The Global Water Crisis March 21 st , 2009 Trinity Western University Langley, B.C., Canada Organized by WaterDrop http://www.waterdrop.ca Photo courtesy and (c) charity:water
  • Agenda
    • Brief facts about global water issues
    • Canada’s water
    • Water stress, virtual water and water footprint (new tools for old problems)
    • A view to the future
  • A few relevant water statistics
    • Only 0.389% of the world’s water supply is freshwater (i.e. water that can be used for drinking, industrial, agricultural and hygiene purposes).
    • Less than 1% of the water on planet Earth is in lakes, rivers, reservoirs, wetlands and aquifers.
    • 1.1 billion people live without clean drinking water.
    • Nearly 41% of the world’s population (2.3 billion people) live in river basins under water stress (per-capita water supply of less than 1,700 m 3 /year). By the year 2025, it is estimated that nearly 2 out of 3 people worldwide will live in an area under high water stress.
    • Daily per-capita consumption of water in North America is, on average, 350 litres. In sub-Saharan Africa, consumption is 10-20 litres.
    • 3, 900 children die every day from water-borne diseases.
        • Sources: World Water Council 2008, WHO 2004, FAO 2008, Revenga 2005, World Resources Institute 2006, World Water Assessment Report 2005.

  • Who has the most available water, worldwide?
  • Who withdraws the most water, worldwide?
    • Surprisingly (in comparison to other countries), Canada’s primary water use is in energy production (thermal power).

  • Wastewater governance in Canada
  •  
  • Water stress (worldwide/Canada) http://www.cgiar.org/enews/june2007/story_12.html
    • Virtual water is the amount of water that is embedded in food or other products needed for its production. For example, to produce one kilogram of wheat we need about 1,000 litres of water, i.e. the virtual water of this kilogram of wheat is 1,000 litres. For meat, we need about five to ten times more. [World Water Council]

  • Water footprint The ‘water footprint’ of a country is defined as the volume of water needed for the production of goods and services consumed by the inhabitants of the country. ( Water Footprint.org – map also (c) of Water Footprint.org)
  • Closing the hydrological cycle http://maps.grida.no/go/graphic/urban_water_cycle
  • Further reflections
    • Canada lacks a national, coherent and cohesive water policy.
    • The state of Canadian water is at times, uncertain (mapping, inventories).
    • Need to have a holistic, comprehensive view of the hydrological cycle
    • I hope that what you take from this lecture, you will apply in your every day life!
  • Thank you!
