Table 2 Summary of the pros and cons of adaptation actions in the Seychelles
From: Identifying and Overcoming Barriers to Climate Change Adaptation in the Seychelles
Adaptation actions | Pros | Cons |
|---|---|---|
Hard engineering techniques | ||
Retaining wall and groynes | Protects coastal and critical infrastructure | Very expensive to set up and to maintain |
Rock armoring | Rocks absorb the wave energy and hold beach material | Logistically difficult to organize |
Soft engineering techniques | ||
Timber piling | Physical barrier protecting unprotected dune-land | Timber may get used up over time |
Beach nourishment | Replenishment technique helpful in coastal defense management | Requires constant importing of sand |
Sand dune management | Prevent the loss of sediment on the beach | Requires careful maintenance |
Ecosystem-based adaptation | Use the role of ecosystem services to respond to the adverse impacts of climate change | Needs to be combined with other techniques |
