Life Now • Do we build in vulnerable zones?

• Do we flood?

• Do we destroy natural mangrove habits?

• Do we properly manage our freshwater resources?

• Do we have access to clean and safe water?

• Do we manage runoff properly?

Our Future • Will we have more droughts?

• Will we have more intense rainfall?

• Will our temperatures increase?

• What will be the level of the sea?

our future

Historic sea-level rise:

a. 0 mm/yr (Suriname)

b. 1.3 mm/yr (Venezuela)

c. 1-3 mm/yr (Insular Caribbean)

The Intergovernmental Panel on Climate Change (IPCC)

predictions over the next century:

2 mm/yr – 9 mm/yr

Interconnectedness • How will sea level rise impact coastal aquifers & water

supplies?

• How will sea level rise impact critical industries?

• How will sea level rise impact built infrastructure?

• How will sea level rise impact food?

Impacts on Aquifers

Barbados West Coast aquifers already showing signs of salt water intrusion

Grenada 1.0 SLR will lead to salinisation of wells in South peninsula of Grenada

Guyana Coastal aquifers already experiencing salt water intrusion. Will >> with SLR


IMPACTS ON TOURISM SEA LEVEL RISE(SLR)

• Impacts of SLR significant for all states (average capital costs of up to 48% of GDP in 2080)

• Rebuild costs disproportionately high for smaller island states

• Rebuild costs of tourist resorts very high in many cases (average of up to 28% of GDP in 2080)

• Key infrastructure (ports, airport and power plants) in most countries vulnerable to 1m SLR

• Impacts increase significantly from 2050 to 2080
