  • impacts of climate change in Africa
    • vulnerability
      • more than 1/4 of population live within a 100om of coast
      • 1/3 live in drought prone areas
      • more than 60% of world population growth between 2008 and 2100 will be in sub-Saharan Africa
      • 14 countries suffering from water scarcity in 2007
      • two million people die of aids each year
      • 75% live in rural areas -agriculture land is poor
      • half of population live on less than $1 a day
      • 2/3 of Africa at LEDC's
      • population dependent on climate sensitive resources
        • water
      • make least contribution to global warming but are more vulnerable to climate change
      • Political turmoil can mean the appropriate responses aren't made
    • Positive
      • tropical areas experience longer growing periods
        • may benefit financially due to better conditions
      • in areas that precipitation does not change fertilisers will receive more CO2
        • could benefit agriculture
      • world tourism organisations predict decline in peak summer visit but stronger winter  tourism
        • creates two potential markets
      • animals attracted to water wells
        • increased tourism
    • negative
      • by 2100 semi arid and arid regions will expand by 5-8%
      • agricultural losses in northern, western, central and southern parts of Africa
        • between 0.4-7% of GDP
      • global warming causing more erratic climate
        • Mozambique suffered drought and widespread crop failure in 1995 + flooding in 2000
          • home + infrastructure destroyed
            • in places  which cannot recover from it
      • desertification in  Sahel Region
        • decrease agriculture production affecting unemployment etc
      • 70% are subsistence farmers
      • 80% of health services rely on wild plants for remedies
      • potential costs for adaptation at least $10 billion
        • more likely to be $30 billion by 2030
      • movement of refugees to coast causes increasing pressure
        • increased shanty towns e.g. Lagos vulnerable to sea level rise
          • flooding in coastal areas could cause $55 billion worth of damage
            • if temperatures rose by 2degrees
      • loss of tourism due to bleaching of coral reefs
      • vector bourne diseases e.g. Malaria could increased
        • overload inadequate health systems and stop people from working
