Lesson details
Key learning points
- Coastal management aims to protect communities and environments.
- There are three main types of coastal management strategy.
- Different stakeholders may have different views on coastal management.
Keywords
Hard engineering - using artificial structures to protect coastlines from erosion and flooding
Soft engineering - making use of natural processes to reduce erosion and flooding in a way that minimises environmental impact
Managed retreat - when areas of the coast are deliberately allowed to flood or erode naturally
Stakeholder - any groups or individuals involved in or interested in changes being made at the coast
Common misconception
Managed retreat is when the land is allowed to erode without any direction.
Managed retreat allows for certain areas to erode or flood in a controlled manner. This approach is often chosen for low value land, where it can create natural habitats and reduce long term maintenance costs.
