Exit strategies to sustain climate resilience and prosperity

This evidence review explores how programme exit strategies can contribute to sustaining climate resilience and prosperity outcomes in coastal communities.

How can programmes ensure their impact lasts long after they formally end?

Produced under the UK Government’s Climate and Ocean Adaptation and Sustainable Transition (COAST) programme, this evidence review examines how exit strategies can actively contribute to sustaining outcomes, rather than simply marking the conclusion of programme activities.

It offers a concise synthesis of recent literature on sustainability concepts, academic theory and practical considerations for designing effective exit strategies and sustainability plans.

We explore:

  • The use of exit strategies and sustainability plans in programming
  • How long-term outcomes can be sustained
  • How wider systemic conditions influence sustainability
  • Conclusions and recommendations for stakeholders

Effective programmes do not automatically translate into sustainable ones; exit and sustainability are highly contextual – though complimentary.

This review aims to support more deliberate, informed planning for long-term impact across the COAST programme and beyond.
