What we will address

What We Will Address

  • What’s the Problem?

  • Hypothesis

  • Relevant Research and Findings

  • Future Concerns

  • Preventative Measures

  • “Take Home Message”


Hypothesis

Hypothesis

If global water scarcity issues are not addressed today, it will greatly limit future sustainability.

Introduction

Introduction

  • Effects of water scarcity not felt everywhere

  • However, one billion people lack access to clean drinking water (1/6 world population)

(www.nadir.org/.../txt/2002/waterscarcity.htm)


Introduction cont d

Introduction Cont’d

  • Water is not being recycled efficiently

  • Water pollution rate is higher than natural purification rate

  • Only 0.009% of earth’s water is readily available for use (Al-Sofi, 1994)


Results and discussion

Results and Discussion

  • Lack of abundant usable water creates tension among countries

  • Many countries are at a geographic, water-deprived disadvantage

  • Treaties that do exist are localized and generally ineffective

Implications cont d

Implications Cont’d

  • Many global implications

    • Health Care

      • 10,000-20,000 children killed by water-related diseases everyday

  • Environmental

    • 20% of all freshwater fish species are now threatened or endangered (Gleick, 2001)

Solutions

Solutions

  • Implement efficient recycling/reclaimation system for irrigation water

    • 3.4 Billion gallons drinking water saved, enough to support 31,000 families

    • Only 2.3% wastewater is currently recycled

    • $26 Million could be saved in Los Angeles County in water transportation costs if efficient recycling implemented (Arrandale, 2002)


Our solutions

Our Solutions

  • Develop and mandate more efficient household water heaters

    • Heated Pipes

    • Better Insulation throughout system

    • Effects: Conservation, lower heating costs

(Shane’s Basement)


Our solutions1

Our Solutions

  • Compose new multinational treaties to address:

    • Water sharing

    • Eliminating unequal distribution

    • Allocate with regard to aridity of region


Conclusion

Conclusion

  • Consumption continues to steadily increase while water remains limited

  • Must be addressed for future sustainability

  • More than one solution is needed to solve problem
