Establishing nature-based solutions for coastal resilience
Restoring ecosystems and their functions
Developing climate change adaptation; improving risk management and resilience

The Dutch coastal zone is prone to flooding. The Netherlands has chosen to protect the coast by means of soft adaptive solutions such as (mega) suppletions with the aim of maintaining the coastline (…) Before the construction of the sand engine, some 12 million cubic metres of sand suppletions were dumped along the Dutch coast annually. ...

Sustainable flood risk management: It will provide a higher standard of protection to the area
Creation of compensatory intertidal habitat: Delivering 183ha of intertidal habitat, including mudflat, saltmarsh and transitional grassland.
Involvement of local communities: Creating new access routes and viewpoints

Passive enhanced boulder with water retention feature uppermost.

Ecological enhancement of hard coastal structures. Project aimed to mitigate expected habitat losses associated with improving coastal defences for both the natural substrate & pre-existing defences within Natural 2000 site, & minimise future habitat losses due to sea level rise & coastal squeeze.

1 Restore a more natural hydrological functioning that reconnects the surrounding hydrosystems (including the lagoons located further inland, the Mediterranean Sea and the Rhône River).

2 Restore the natural ecosystems characteristic of coastal lagoons and sandy coastlines, including dunes, salt steppes and saltmarshes.

3 Maintain or increase the carrying capacity for breeding colonial water birds.

4 Implement adaptive management to sea-level rise, creating accommodation space for water spread.

One of the consequences of global warming is the sea level rise. In urban settings along coastlines, rising seas threaten not only houses, but also several types of infrastructures such as industries, roads, power plants, freshwater aquifers, etc. Rising sea-level also pushes destructive storm surges further inland, posing very high risks for coastal populations, as storm surges can push water kilometers inland, causing extreme flooding far from the coast.

The Portuguese ReDuna project aims to restore the natural capacity of the Almada sand dune-beach ecosystem to healthily...

The Medmerry scheme realigned a section of coast to deliver better protection from coastal flooding for local people and to provide intertidal habitat for nature.
