Coastal tectonics and habitat squeeze

We're pleased to announce publication of a new paper in the international journal Natural Hazards.
This is the first chapter in the 'Resilient Shorelines' Ph.D.

The Canterbury earthquakes provided a rare opportunity to observe the actual effects of a sea-level rise event. This study explores the impacts of hydrological changes resulting from tectonic ground movement in low-lying coastal environments, and draws analogies with future climate change.

The paper describes landscape-scale changes and assess interactions with human land-use patterns and disaster recovery responses that include a large scale managed retreat. The results illustrate mechanisms by which 'coastal squeeze' effects may occur with sea-level rise - and also ways to avoid them through innovative planning and design.  

Principles identifiable from the actual impacts in this case provide useful insights for other situations of sea-level rise.

We highlight the need for an improved focus on whole-system resilience in responding to sea-level changes, and the importance of disaster recovery processes for adaptation to climate change.
