Three Key Strategies for Adapting to Sea-Level Rise

Three Key Strategies for Adapting to Sea-Level Rise

Benefits of Taking Action Early to Prepare for Sea-Level Rise (SLR)

  • Planning Ahead Means Adaptation Actions Can Be Strategic and Phased. Early planning can allow coastal communities to adopt a phased approach that undertakes escalating actions when certain predetermined conditions or “triggers” are reached.
  • Undertaking Near-Term Actions Can “Buy Time” Before More Intensive Responses are Needed. Putting certain adaptation projects and strategies in place now can help postpone and extend the period before which subsequent, more difficult-to-implement actions are needed.
  • Early Implementation Provides the Opportunity to Test Approaches and Learn What Works Best. Acting to implement adaptation strategies in the near term will provide the opportunity to monitor, evaluate, and revise them in the coming years before SLR threats become more pressing.
  • Taking Action Earlier May Make Overall Adaptation Efforts More Affordable. Undertaking a multiyear, multistep strategic plan for coastal adaptation can allow local governments to spread costs over a longer period of time.
  • Coming Decade Is Key Window for SLR Preparation. Some adaptation strategies—such as fortifying certain tidal marshes—may not be effective against SLR unless they are implemented before sea levels rise to higher levels.
