Coastal Zones in General (CZ)

Climate Change Impacts and Needs in Asia-Pacific Region
Coastal Areas in General (CZ)
Changes in Climate Factors
  • Sea level rise
  • Increase in extreme events (tropical cyclones, storm surges, etc.)
  • Changes in precipitation
  • Air and water temperature rises
Primary Impacts
  • Inundation of low-lying areas, submergence of swamps and wetlands
  • Coastal erosion of beaches, etc.
  • Salt water intrusion, increased salinity of rivers, bays, and aquifers
  • More severe flooding
  • Ecosystem changes (mangrove destruction, wetland ecosystem deterioration, etc.)
  • Increases in pathogens of water-borne diseases
Natural/Social Factors
  • Low-lying coastal zones
  • Location in area affected by tropical cyclones
Secondary Impacts
  • Loss of human life due to extreme events, worsened health due to increase in disease, etc.
  • Land loss (loss of habitable land, farmland, aquaculture fame, etc.)
  • Loss of areas fit for safe and healthy habitation due to increased flooding
  • Increased risk of infrastructure destruction and damage
  • Decrease in water resources
  • Loss of increased salinity of farmland, reduced productivity of agriculture, loss of livelihood
  • Flagging tourism, fishery
Natural/Social Factors
  • Presence of fisheries, agriculture
  • Developed water transportation system
  • Different levels of coastal protection
  • Different levels of sanitary conditions
Needs and Changes
  • Projection/assessment of impacts/vulnerability
  • Control of erosion/inundation (retreat, defense, drain, etc.)
  • Measures against flooding, storm surges, etc. (avoid/minimize damage)
  • Conservation/securing of water resources
  • Measures to conserve soil/water quality for agriculture/fisheries
  • Sanitation measures (improve water treatment, enhance sanitation practices, etc.)
  • Measures for tourism, fishery, aquaculture industry
