Managed Retreat: What is it?

When an area of land is allowed to flood. Usually land considered to be of low value is

sacrificed to protect an area of higher value, such as a tourist hotspot that is important to a local economy, or an urban area where more people would be more severely affected by flooding or landslides.

Managed Retreat: Why is it done?

A defence for more valuable areas further inland or further along the coast.

To create a new wetland habitat for wildlife, such as migrating birds.

ICZM: What is it?

Stands for Integrated Coastal Management Zone.

Includes the built-up areas near the coasts, as well as the shore line.

Produces a plan that dictates how a coastal zone should be effectively managed.

ICZM: Why is it implemented?

To protect coastal areas from over-development and environmental damage.

These are ever increasing threats in our modern world where development rates are more rapid than ever to facilitate the needs and desires of our planet’s escalating population.

Managed Retreat Case Study – The Wallasea Wetlands

Part of a government-funded wetlands scheme to halt the decline of wild and endangered birds caused by the drainage and development of former wetland sites.

Largest man-made marine wetland area in the United Kingdom (115 hectares).

Created by the implication of managed retreat. Construction completed 2006. By 2011 it had evolved

into wetland, mudflats, saline lagoons and seven artificial islands, allowing the wildlife to reside on these areas.

In what ways is it put under pressure? Increasing levels of sea pollution: industrial waste and

untreated sewage are pumped into the sea as treatment plants struggle to facilitate huge increases in demand for their services.

Increased urbanisation of coastal areas as population increases (especially in holiday season).

Growing threat of desertification as increasing amounts of underground water are removed to make way for developments.

Water shortages because of increases in demand and climate change.Introduction:

ICZM Plan Case Study – The Mediterranean Coast

What has the ICZM Plan recommended? Reduce building development along the coast and introduce

protected ‘green areas’ between areas of development. Develop inland tourism to relieve pressure on the immediate

coast. Issue guidelines to ensure that tourist developments is

environmentally considerate. Treat all waste water before it is pumped into the sea to

reduce pollution and harm to marine life. Encourage energy-saving measures and the development of

renewable energy.Introduction:Managed Retreat

ICZM Plan Case Study – The Mediterranean Coast

Summary: Managed Retreat

Advantages Disadvantages More natural than hard

engineering. Has less of a visual and

environmental impact than hard engineering.

Encourages the build-up of naturally defensive beaches.

Cheaper than hard engineering and generally less labour-intensive than beach management.

There is no real control over the movement of the sea inland.

There are costs involved, such as compensating people for lost farmland and properties.

ICZM

Advantages Disadvantages A dedicated plan from a powerful

organisation, such as the EU or UN, ensures long term protection without conflict between local authorities.

ICZM looks at the bigger picture of coastal management: it thinks about the impacts for the whole coastal zone, rather than each local authority implementing strategies for protecting their vicinity without considering the effect on other nearby locations.

ICZM is just a plan that provides recommended solutions to coastal problems – governments may oppose the suggestions made due to lack of funds or conflict of interest.

Not all countries in a coastal zone have to ratify the ICZM Protocol created for that area. In the Mediterranean, for example, not all of the twenty countries in the zone have agreed to implement the suggested strategies.Introduction:
