The Netherlands. The first island was inaugurated on 24 September 2016.
Work on the first phase, which is mainly focused on the construction of the first island, started in April 2016.
The main aims of the project are to create breeding grounds, islands, and coast line as well as to improve the water ecology of the Markermeer. The project creates a wetland comparable with the Wadden Sea—hence the name of the project—yet without tides. This is because the Markermeer is not connected to the sea and is in a fresh water environment. The new nature reserve will be accessible to tourists.
On 11 May 2016, the first new land was created, which Natuurmonumenten called a "milestone". In March 2017, it was announced that four other islands should be completed before 2020.
