Managed Retreat is a coastal management strategy that involves relocating people, infrastructure, and ecosystems away from the coast to higher ground, typically in response to environmental challenges such as sea-level rise, erosion, and storm surges. The effectiveness of Managed Retreat as a strategy for coastal urbanization in the face of environmental challenges and sea-level rise can be evaluated from several perspectives.
Benefits:
- Reduced risk: Managed Retreat can significantly reduce the risk of loss of life and property damage from natural disasters, such as hurricanes, tsunamis, and flooding.
- Preservation of ecosystem services: By relocating habitats and ecosystems to higher ground, Managed Retreat can help preserve biodiversity and maintain ecosystem services, such as coastal protection, water filtration, and carbon sequestration.
- Cost savings: Relocating infrastructure and development can be more cost-effective than attempting to protect them in place through costly flood defenses or other hard engineering measures.
- Enhanced resilience: Managed Retreat can promote community resilience by providing a safe and stable environment for future generations.
Challenges:
- Complexity: Managed Retreat involves complex decision-making processes, requiring coordination among multiple stakeholders, including government agencies, local communities, and private developers.
- Cost: Relocating people and infrastructure can be expensive, especially when considering the costs of acquiring land, relocating businesses and services, and providing new infrastructure.
- Social impacts: Managed Retreat can lead to social displacement, loss of community identity, and disruption to cultural heritage.
- Land availability: Finding suitable replacement land for relocation can be challenging, especially in areas with limited land availability or competing demands for space.
- Implementation: Managed Retreat requires significant changes to existing land-use plans, zoning regulations, and building codes, which can be slow and contentious.
Case studies:
- The Netherlands: The Netherlands has successfully implemented Managed Retreat in several locations, including the Zuidplaspolder area, where a large-scale dike was constructed to protect the surrounding areas.
- New Orleans: After Hurricane Katrina devastated the city in 2005, the U.S. Army Corps of Engineers implemented a managed retreat strategy for the Lower Ninth Ward, relocating residents to higher ground and restoring wetlands.
- Mangroves: In some mangrove-rich coastal regions, managed retreat has been used to restore natural habitats while protecting communities from storm surges and sea-level rise.
