Costal community

  1. 1. Coastal Community Resilience Against Disasters Presented by • Cdr M Dagar • Wg Cdr KM Rakesh • Mrs Bharti Katre • Mr M Hussain
  2. 2. COSTAL ZONE • The coastal areas are defined as areas between 50 meters below mean sea level and 50 meters above the high tide level, or extending landward to a distance of 100 kilometers from shore, including coral reefs, intertidal zones, estuaries, coastal aquaculture, and sea grass communities (UN Millennium Ecosystem Assessment, 2003 : 54)
  3. 3. COASTAL FEATURES
  4. 4. COASTAL ZONE PHYSICAL CHARACTERISTICS
  5. 5. COSTAL STATISTICS • According to the UN atlas, 44% of people live within 150 Kms of the sea. • 60 % of the world’s 39 metropolises with a population of over 5 million are located within 100 km of the coast. • 14 of the world’s 17 mega cities with populations greater than 10 million are on coasts. • According to UNEP report , 1/3 coastal regions run a high risk of degradation.

  9. 9. COSTAL RISKS Risk = Hazard x Vulnerability (frequency & severity) (Exposure & Capacity) (UN International Strategy for Disaster Reduction [ISDR] 2004).
  10. 10. RISKS FROM COSTAL HAZARDS • Risk from coastal hazards are defined by the type and severity of the hazard and its frequency of occurrence. (UN International Strategy for Disaster Reduction [ISDR] 2004).
  11. 11. COSTAL HAZARDS – Tsunamis – Earthquakes – Storms – Storm Surge – Flooding – Landslide
  12. 12. – Spills & Pollution – Shoreline Erosion – Sea Level Rise – Climate Variability & Change – Costal Resource Degradation COSTAL HAZARDS
  13. 13. VULNARABLITY TO COSTAL HAZARDS • Vulnerability to coastal hazards is expressed as the degree of exposure of the population and its capacity to prepare for and respond to the hazard. (UN International Strategy for Disaster Reduction [ISDR] 2004).
  14. 14. REASONS OF COSTAL COMMUNITY VULNERABLITY
  15. 15. COSTAL COMMUNITY RESELIANCE (CCR)
  16. 16. DEFINITIONS OF RESILIENCE “Resilience determines the persistence of relationships within a system and is a measure of the ability of these systems to absorb change of state….and still persist.” - (Holling 1973)
  17. 17. DEFINITIONS OF RESILIENCE • “…Resilience for social-ecological systems is often referred to as related to three different characteristics: (a) the magnitude of shock that the system can absorb and remain within a given state; (b) the degree to which the system is capable of self-organization, and (c) the degree to which the system can build capacity for learning and adaptation.” - (Folke et al. 2002)
  18. 18. DEFINITIONS OF RESILIENCE ‘’The capacity of a system to absorb disturbance and re-organize while undergoing change so as to still retain essentially the same function, structure, identity and feedback.” - (Walker et al. 2004)
  19. 19. COSTAL RESILIENCE CYCLE
  20. 20. ROLE OF RESILIENCE IN RESPONSE TO HAZARD
  21. 21. RESILIENCE AS AN INTEGRATING FRAMEWORK
  22. 22. COASTAL RESILIENCE ELEMENTS
  23. 23. ELEMENTS OF CCR • Governance • Society & Economy • Costal Resource Management • Land Use & Structural Design
  24. 24. ELEMENTS OF CCR • Risk Knowledge • Warning & Evacuation • Emergency Response • Disaster Recovery
  25. 25. BENCHMARKS FOR CCR • Policy & Planning Capacity • Physical & Natural Capacity • Social & Cultural Capacity • Technical & Capacity
  26. 26. CONCLUSION
  27. 27. CONCLUSION • P…………..
