  1. 1. I S L A M I C R E P U B L I C O F I R A N M I N I S T R Y O F R O A D S A N D U R B A N D E V E L O P M E N T R O A D , H O U S I N G & U R B A N D E V E L O P M E N T R E S E A R C H C E N T E R ( B H R C ) Achievements of BHRC in urban resiliency Ghazal Raheb Head of Architecture and Urban Planning Institute, BHRC Mahta Mirmoghtadaee Head of Theoretical Studies in Architecture and Urban Planning Department, BHRC
  2. 2. Definition As the“city”is considered a dynamic system, the ability of this system to return to stable equilibrium point after disruption is “RESILIENCY”.
  3. 3. Environmental management and risk reduction Two determining factors threatening Contemporary human settlements are:  Deterioration of environment  Natural disasters Deterioration of environment increases the adverse impacts of natural disaster. Current human life style has put more people and structures under risk and more pressure on environment. Reducing natural disaster risks and achieving “livable”, “Sustainable” and “Resilient” urban and rural settlements are dependent on environmental management.
  4. 4. Analytical review of settlements resiliency in disasters (South Khorasan eartquake- 1997) Unsustainable location: Locating on the slopes, Instable soils and , high risk zones
  5. 5. Unsustainable development: Construction on the river bank Destroying forests in highlands was leading to flooding Analytical review of settlements resiliency in disasters (Flood in Neka- 1999)
  6. 6. Unsustainable urban form Compactness of neighborhood in Bam after earthquake Open spaces in urban fabric, Baravat (a town near Bam) after earthquake Analytical review of settlements resiliency in disasters (Bam earthquake- 2003)
  7. 7. Unsustainable location: Establishing villages in valleys and steeps Unsustainable and poor access to some villages Analytical review of settlements resiliency in disasters (Azarbayjan earthquake- 2012)
  8. 8. Planning for increasing Resiliency in settlements 1. Prevention 2. Rescue and Relief 3. Rehabilitation and Reconstruction
  9. 9. First step: Planning for prevention of settlements against disasters Introducing some of the main achievements of BHRC:  providing effective data bases for risk reduction strategies and plans  Providing building codes for risk reduction  Local indicators for risk management and providing codes and regulations for risk reduction in built environment  Research on urban regeneration and low-income housing  Training courses for planners, architects and civil engineers
  10. 10. providing effective data bases for risk reduction strategies and plans (introducing some activities)  Control and Maintenance of Iran Strong Ground Motion Network  Classification of Rural Settlements based on rural housing types  Preparation of seismotectonic map of Iran on scale of 1:2500000  Preparation of seismic zonation hazard map of Iran (Standard 2800 annex)  Information layer project in earthquake disaster management  Microzonation of urban regions
  11. 11. Distribution of Iran Strong Ground Motion Network
  12. 12.  Zone 1: The Oman Sea and the Persian Gulf littoral  Zone 2: Caspian Sea fringes  Zone 3: Mountainous Kurdish settling areas of West  Zone 4: Azari settling areas in North West  Zone 5: Mid Alborz district and eastern Zagros plains  Zone 6: Settled Nomads and permanent residents of the western Zagros foothills  Zone 7: Central and eastern plains of Iran  Zone 8: Central highlands and plains in the central and eastern mountainous fringe areas Basic (or lead) rural housing formation “types” zones in Iran
  13. 13. Seismic microzonation hazard map in Iran
  14. 14. Providing building codes for risk reduction (introducing some activities)  Iranian code for seismic resistant design of buildings (standard No. 2800)  Fire protection building code  Evaluating the strength of buildings and presenting technical comments relevant to retrofitting existing buildings  Passive defense strategy
  15. 15. Research on urban regeneration and low-income housing  Infill development  Evaluation of urban regeneration projects  Comparative studies on urban regeneration projects  Studies on the role of public participation  Introduction of best practices  Design consideration for low-income housing  Documentation of low- income housing projects
  16. 16. Theories and best practices of urban regeneration (Iran and Meddle East , North African countries) Training courses of planners, architects and civil engineers
  17. 17. THE SECRETARIAT OF DOCUMENTING BEST PRACTICES IN DISASTER REDUCTION AND POST-DISASTER RECONSTRUCTION
  18. 18. A best practice is a method or technique that has consistently shown results superior to those achieved with other means, and that is used as a benchmark. A "best" practice can evolve to become better as improvements are discovered. Best practice describes the process of developing and following a standard way of doing things that multiple organizations can use. Definition of best practices
  19. 19. Objectives of the secretariat The secretariat is established with the objective of documenting the best practices in mitigation of disaster risks before and after occurrence in Asian- Pacific countries, which includes two steps:  Measurements taken before a disaster strikes with the objective of increasing built-environment resilience;  Measurements taken in post-disaster construction with developmental approach and with the objective of improving resilience of new physical environment and in fact as an opportunity for pursuing sustainable development.
  20. 20.  Measurements on spatial and physical regeneration of built- environment in urban and rural settlements;  Measurements on improving access network in urban and rural settlements;  Measurements on improving infrastructures of water, waste water and energy supply in rural and urban settlements;  Measurements on strengthening and reinforcement of important structures and residential buildings;  Rules and regulations;  Management, evaluation and control quality systems;  Conducted pilot projects with the objective of dissemination and generalization  Training programs for enhancing general and technical knowledge in the above mentioned fields.
