Change Factor Potential Impacts on the Coast
Sea Level Rise
1. Flooding and inundation of low lying areas and coastal communities
2. Dislocation of coastal communities
3. Land loss
4. Saltwater intrusion
Hurricanes/Storm Surge
1. Increased coastal erosion and damage to coastal infrastructure and buildings
2. Loss of Tourism Investments and subsequent negative impact on employment
3. Increased likelihood of flooding
4. Increased risk to human life and risk of infectious disease

Integrated Coastal Integrated Coastal Planning and Management Planning and Management
(ICPM)(ICPM)ICPM is dynamic process in which a coordinated strategy is developed and implemented for the allocation of environmental, socio-cultural and institutional resources to achieve the conservation and sustainable use of the coastal zone (Sorensen, 1993).It is an evolutionary and iterative processResponds to changing conditions-effects of climate change
