Coastal ecosystems such as mangroves, saltmarshes, coral reefs barrier islands and sand dunes
• Coastal ecosystem function as a continuum of natural buffer system protecting against hurricanes, storm surges, flooding and coastal hazards:
A combined protection from coral, seagrass beds and sand dunes /coastal wetlands / coastal forests is particularly effective.
• Coastal reefs and coastal wetlands such as mangroves and saltmarshes absorb wave energy. reduce wave heights and reduce erosion from storm and high tides.
• Coastal wetlands buffer against saltwater intrusion and adapt to sea-level rise by trapping sediments and organic matter.
• Non-porous natural barriers such as sand dunes and barriers , islands dissipate wave energy and acts as barrier against waves, currents, storm surges and tsunami.
Drylands
• Natural vegetation management and restoration in drylands contributes to ameliorate the effects of drought and control desertification
• tree, grasses and shrubs conserve soil and retain moisture.
• Shelter belts, green belts and other types of living fences act as barrier against wind erosion and sand storms.
• Maintaining vegetation cover in dry land areas and agricultural practices such as use of shadow crops; nutrient enriching plants and vegetation litter increases resilience to drought
