Welcome to africa l.jpg
Welcome to Africa

  • Current Conditions

    • Decline in water resources

    • Insufficient food

    • Sanitation issues

    • Extreme, unpredictable weather

  • 300 million people affected

  • What are the effects of water scarcity in Africa?

  • http://www.pewfellowships.org/resources/stories/zimbabwe_images/main_zimbabwe.jpg


    Zimbabwe l.jpg
    Zimbabwe

    • Natural Adversity

      • Population density

      • Climatic conditions

      • Landlocked geographic location

    • All lead to water supply problems

    http://www.unido-aaitpc.org/unido-aaitpc/new1/images/map_zimbabwe.gif


    High population density l.jpg
    High Population Density

    • Overcrowding adds to strain on resources

      • Housing

        • Multiple families in close proximity

        • No running water

      • Communal Well

        • Women and children fetch water

      • Communal Facilities

        • Designed for 8 people, now shared by over 50 people

    Sanitation issues l.jpg
    Sanitation Issues

    • Stem from overpopulation and inefficient infrastructure

      • Toilet

        • Same drain as shower

        • Blockages from use of newspaper as toilet paper

      • Pipe system

        • Bursts

        • Slow repair time

      • Contaminated water

        • Sakubva River

        • Children’s infected play area

    Health risks l.jpg
    Health Risks

    • Observed at Zimbabwean Health Clinics

      • Daily patient increase

      • Stem from contact with contaminated water

      • Specific diseases include:

        • Tuberculosis

        • Cholera

    Climate conditions l.jpg
    Climate Conditions

    • 3 distinct seasons

      • Ranging from hot to cool and wet to dry

  • Unpredictable floods and droughts

  • Annual Average rainfall is 685 mm

    • 300-500 mm can come in one month

  • Difficult to plan crop cycle

    Agriculture l.jpg
    Agriculture

    • Agricultural nation

    • Inconsistent harvests

      • Leads to malnourishment

      • Struggle for financial stability

    Possible solutions l.jpg
    Possible Solutions

    • Improved Infrastructure

    • Solar Stills

    • Conservation efforts

    • Spreading awareness

    http://www.villagehealth.org/Dsc00404.jpg


    Infrastructure l.jpg
    Infrastructure

    • International

      • Necessary because they are landlocked

      • Expand current system

    • National

      • Improve and increase existing system

    • Drawbacks

      • Need international cooperation

      • Leakage

      • Expensive – small countries can’t afford
