Transcript

  • 1. World At Risk<br />GLOBAL HAZARDS<br />
  • 2. There are different types of hazard:<br />Hydro Meteorological Hazards<br />Caused by climate processes, these include droughts, floods, tropical cyclones/storms<br />Geophysical Hazards<br />Caused by land processes, these include earthquakes, volcanic eruptions and landslides.<br />
  • 3. DISASTER<br />- When a hazard actually seriously affects humans<br />RISK<br />- The likelihood that humans will be seriously affected by a hazard <br />VULNERABILITY<br /><ul><li>How susceptible a population</li></ul> is to the damage caused by a hazard<br />
  • 4. THE DISASTER RISK EQUATION<br />Hazard [H] X Vulnerability [V]<br />Risk [R] = <br />Capacity to cope [C]<br />The risk of a disaster increases as the frequency or severity of hazards increases, people’s vulnerability increases and people’s capacity to cope (ability to cope with the consequences) is decreased. <br />
  • 5. Another reason why it may seem that the number of disasters has increased is because of greater media coverage – more disasters are reported than in the past, so it seems as if more are actually happening<br />Hydro meteorological hazards are becoming more frequent <br />Its thought that the increase in hydro meteorological hazards is due to the increasing effects of global warming - which is thought to be largely due to human activity <br />The number of geophysical hazards hasn’t changed much<br />
  • 6. There are a number of factors why disasters are increasing:<br />
  • 7. Deaths are decreasing but economic losses are increasing <br />Deaths from disasters have decreased due to improvements in risk management strategies:<br /><ul><li>prediction - improved technology means some hazards can be predicted e.g. The path of tropical cyclones can be predicted to some extent. Advance warning means people can be evacuated and property secured
  • 8. prevention - natural hazards can’t be stopped, but they can be prevented from becoming disasters, e.g. By using sand bags to protect against the effects of flooding
  • 9. preparedness - educating people on what to do in case of a disaster helps to reduce the number of deaths, e.g. Japan has a ‘disaster preparedness day’ each year when practice earthquake evacuation drills are carried out</li></li></ul><li>Global economic losses due to <br />disasters are increasing rapidly<br />Actual financial cost is the amount of money lost - this greatest in richer countries<br />Relative financial cost is the amount of money lost relative to how much the people have to start with – this is greatest in poorer countries. Less actual money is lost, but the effects of the loss are greater <br />
