The sea level is rising and with it the Halligen and their terps are in danger of sinking. The concept "Growing with the sea" shows how the unique tidal landscape can remain habitable in the future.

In 2012, the state of Schleswig-Holstein launched an ideas competition on the future of the Halligen. The concept "Growing with the Sea", which was awarded first prize, shows a way in which all landscape elements can grow with the rising sea level: the Wadden Sea, the salt marsh Halligen, the terps and the residential buildings on the terps.

Growing Wadden Sea
The Wadden Sea with its Halligen is a natural flood protection buffer for the mainland. Deficient sediment input and sea level rise threaten the amphibious landscape. It must be able to grow with the sea level. Sediment traps can be used to create material depots that increase input.

Growing Hallig
Increasing flood periodicity by controlled flooding of salt marshes via existing sloughs and tideways can increase sediment input. A differentiated management approach of grazing, mowing and fallow management will support emergence and biodiversity.

Rising terps
The terps have been adapted and optimized to sea level rise for centuries. The next increase in the height of the terp is in a crescent shape on the west side. On the east side, the terp remains at the existing level so that flood waters can drain away. The height of the mound can always be adjusted to sea level in a sustainable manner.

Growing Hallighaus
Hallig residents must be able to adapt flexibly and quickly to the realities of sea level rise. The Hallighaus 2050 meets this requirement. It stands on a table on piles that can be raised by means of hydraulic supports.
