Vulnerabilities and Small Islands October 24, 2002 COP 8 New Delhi, India
The Maldives
Geography A chain of coral atolls 860 km long, km wide 26 geographical atolls Over 5,000 separate reefs 1,192 islands
Geography - islands average height above mean sea level is 1.5 m over 80% of land area less than 1m above mean sea level size: from 0.5 to 2 sq.km 3 islands greater than 3 sq.km total land area: approximately 300 sq.km
Vulnerabilities to Climate Change 1.Land loss and beach erosion 2.Infrastructure damage and economic impacts 3.Food security 4.Damage to coral reefs 5.Water resources
Sea level rise Most susceptible – least defensible
Land loss and beach erosion 80% land area less than 1 m above MSL
Beach erosion Severe beach erosion in over 50% of islands
Infrastructure damage and economic impacts Airport is extremely vulnerable Ground level of airport does not exceed 1.7m above MSL Runway of airport partly flooded during high wave incidence of 1987
Infrastructure damage and economic impacts Tourism – major source of revenue Marine dive sites at risk Infrastructure damage – investment risks
Fisheries Tuna main source of protein 85kg/yr/capita consumption Main export Tuna affected by seasonal monsoon as well as ENSO events
Food security Agriculture Heavy import dependency Food storage and distribution
Damage to coral reefs Bleaching 80% in shallow water 30-45% at depths of 10-30m
Water resources 25% groundwater 25% desalinated water 50% rainwater
