Climate adaptation
Managed Retreat
Definition
Managed retreat is the strategic relocation of people, assets and activities away from areas exposed to unmanageable climate hazards — coastal erosion, sea-level rise, flooding — rather than defending them indefinitely. It typically involves land acquisition or buyouts, compensation, resettlement support and conversion of vacated land to buffers such as wetlands, and may be embedded in setback zones under integrated coastal zone management.

Overview
What it means
Retreat is usually a last resort after protection and accommodation options become technically or economically untenable. Done well it is planned, compensated and participatory; done badly it destroys communities and heritage.
How it is used
Governments run voluntary buyout programmes after floods; coastal strategies designate setback and no-build zones; insurers and planners use retreat scenarios in long-term adaptation pathways.
Why it matters
As hazards intensify, some locations cannot be defended; fair, well-governed retreat is a defining test of just adaptation, raising hard questions of equity, property rights and cultural loss.
