Risk mitigation in the cities using urban natural elements, Case study Tehran Risk mitigation in the cities using urban natural elements, Case study Tehran

  1. 1. Risk Mitigation in Cities Using Urban Natural Elements: A Case Study of Tehran<br />Solmaz Hosseinioon<br /> <br />IIEES, Tehran ,Iran,<br />Solmaz.hosseinioon@gmail.com<br />
  2. 2. Regarding what makes a city safe and liveable, many aspects of the preparedness for cities have yet to be thoroughly discussed.<br /> <br />Factors:<br /><ul><li> characteristics of emergency access</li></ul>ways and centres<br /><ul><li> urban zoning systems
  3. 3. safety of individual buildings
  4. 4. Location of urban functions</li></ul> in relation to hazardous places<br />
  5. 5. Elements of the natural environment, including urban rivers, hills and lakes, are rarely considered as risk mitigation factors<br />
  6. 6. Urban natural <br />environmental <br />elements contribute to :<br /><ul><li> Sustainable livelihood
  7. 7. Increase the quality</li></ul> of life and public realms<br /><ul><li> Important part of the city’s </li></ul> spatial, perceptual and <br /> structural organization.<br />…and:<br />contribute to safety <br />
  8. 8. Disaster management plans should<br />include locating and defining:-<br /><ul><li> functions
  9. 9. emergency access ways
  10. 10. emergency evacuation centres
  11. 11. emergency medical bases</li></ul>... in neighbourhoods and cities.<br />
  12. 12. Prohibition measures to be included in hazard mitigation plans:-<br /><ul><li> zoning restrictions
  13. 13. vulnerable areas (population, </li></ul> construction deficiencies....)<br /><ul><li> placement of hazardous functions.</li></li></ul><li>Risk areas: -<br /><ul><li> danger zones for earthquake faults
  14. 14. high-tension power lines
  15. 15. landslide and liquefaction zones
  16. 16. river banks and seashores
  17. 17. zones that impinge upon lifelines.</li></li></ul><li>The disaster management elements of cities should correspond to natural and perceptual elements of the city to provide prohibitive and preventive measures<br />A multidisciplinary approach to disaster management will help us to mix urban design guidance plans with risk mitigation plans, which will make them more feasible and multifaceted.<br />
  18. 18. Natural elements in the city:-<br /><ul><li>help improve the feeling of security</li></ul> and environmental safety in people<br /><ul><li>strengthen landmarks both formally and perceptually
  19. 19. help people orientate themselves and find the way
  20. 20. when the urban environment is devastated
  21. 21. can contribute to post-disaster</li></ul>restoration in earthquakes.<br />
  22. 22. Urban rivers:-<br /><ul><li> important parts of cities’ cognitive maps: (edges, routes)
  23. 23. they will remain after disasters such as earthquakes
  24. 24. they can have a great role in way-finding (decision plan)
  25. 25. provide for emergency access ways
  26. 26. be used as emergency source of water for aid</li></ul> and fire extinguishing, transportation means.<br />
  27. 27. Tehran is a metropolitan city about 700 sq km <br />population of more than seven million, a disaster prone city to earthquakes,<br />floods…<br />
  28. 28. Ninerivers which run in north-south valleys:-they average 10 kilometers long and provide 200 sq km of greenery and natural ventilation for the city<br />
  29. 29. They were recreational roads <br />and natural ventilation<br />corridors leading to Alborz <br />mountain ranges, by rapid <br />urban growth have become<br />parts of the city.<br />Sincethe Golabdare-Tajrish <br />flood of 1988 they are<br />considered a threat to the city<br />rather than opportunities <br />for mitigation<br />
  30. 30. .<br />
  31. 31.
  32. 32. Transforming or hiding natural elements<br />will cause increase in risk <br />
  33. 33.
  34. 34. Tehran has consumed most of its natural resources beyond its ecological footprint<br />
  35. 35. Urban rivers, hills, landforms or parks and green openings are rarely considered in designing risk mitigation measures.Froman urban design point of view, combining sustainability measures with risk mitigation will aid urban safety and emphasize the importance of safeguarding natural elements in urban areas and fulfill sustainable development goalsas an interdisciplinary challenge.<br />
