Hansen, L., Hoffman, J., Drews, C., & Mielbrecht, E. (2010). Designing Climate-Smart Conservation: Guidance and Case Studies. Conservation Biology, 24(1), 63-69. Central America / Caribbean SLR will lead to beach losses in the region which in turn will decrease the available habitats for many species. For example, up to 30% of turtle nesting areas would be lost from a 0.5 m rise in sea level. The restoration and protection of native coastal vegetation at nesting sites. Implementation and enforcement of adequate setback regulations creates the potential to maintain the ecological and economic function of beaches in the face of extensive coastal development and sea-level rise.

Burley, J. G., McAllister, R. R., Collins, K. A., & Lovelock, C. E. (2012). Integration, synthesis and climate change adaptation: a narrative based on coastal wetlands at the regional scale. Regional Environmental Change, 12(3), 581-593. Australia Sea level rise will result in landward migration of wetlands as tidal boundaries move upslope. Loss of wetlands on the seaward margin is likely if wetlands cannot accrete as fast as sea level rises. Models of wetland change in South East Queensland indicate that with a 0.64 cm rise in sea level, 50% of the high intertidal and non-saline coastal wetlands may be lost by 2100. 'Hard' adaptation strategies for maintaining coastal wetland areas faced with sea level rise involve technical and engineering solutions, such as infrastructure design, removal and construction of walls/built structures and wetland restoration. 'Soft' adaptation strategies involve knowledge, knowledge generation processes (such as models, regulations, standards of practice) and information systems (models), and changing the institutional, financial and legal infrastructures.

Ocean & coastal management, 37(1), 63-83. Southeast Africa: Mozambique The sea water will inundate the low relief marshes which will openly connect to the sea following erosion of the existing beach ridge beyond the sea wall. The remaining coastal ridges will be overwashed by waves and the low relief plains will be inundated by sea water. The National Environmental Management Programme (NEMP) establishes integrated coastal zone management (ICZM) that will be based on coordination between the relevant stakeholders (institutions and communities) and on a programme which should be designed and accepted by them. The main issues for this programme are (1) fisheries, (2) coastal and marine ecosystems management, (3) coastal and marine protection, (4) marine parks and (5) tourism.
