• Whether schemes put in place or not depends on cost-benefit analysis eg:
- Easington - 25% of UK gas from North Sea arrives here = boulders put in place
-Spurn Head - Very thin and could easily become an island which would destroy salt
marshes however still no scheme in place (groynes further up are reducing its sand-
supply)
• CONCLUSION = Highlights importance of cost-benefit analysis (whether benefit out-
weighs cost depends on where priorities lie eg economic or env. gain)
IMPORTANCE OF MANGROVES IN PROTECTING TROPICAL COASTLINES (JAMAICA):
• Lack of housing and hotels for growing tourism industry
• Loss of 60% of mangroves by 2010 as needed to build Dragon Bay Resort
• Success or failure?
- Tourism now provides 75% of GDP (higher income for locals = improved SoL)
- Increased flood damage (less protection from groves) eg Hurricane Ivan in 2004
damaged 75% of newly-built houses
- Some locals unhappy, tourism = pollution (noise, air etc), ruined aesthetic appeal
- Mangroves provide flood protection, fuelwood source, home for fish and birds,
stabilisation of soil, absorption of inorganic material that would flood into sea

• 180 hectares of new salt marshes built
• Locals involved in every stage
