In 2020, the artists collective Onkruidenier (Ronald Boer, Jonmar van Vlijmen, and Rosanne van Wijk) researched the landscape around Beetsterzwaag to find out which visible and invisible relations with the sea could be discovered. Their artistic research marks a new chapter in their ongoing project SWEET – SWEAT, in which they investigate the relationship between ‘sweet’ and ‘salty’ in the landscape and in our bodies at various locations in the Netherlands. For Langstme, Onkruidenier presents an installation with tools that allow us to mediate between humans and a retreated sea. Some of the tools were developed in collaboration with Studio Kai Udema.

De Onkruidenier (since 2014) started as a collaboration between Jonmar van Vlijmen and Ronald Boer. Both are trained as landscape architects and visual artists. Their work has previously been shown at various locations in the Netherlands and abroad (including Oerol, New Rotterdam Institute and the Ruimtekoers Festival). In 2019, Rosanne van Wijk joined the team of the Onkruidenier. Rosanne van Wijk (1994, NL) graduated cum laude from the BA Fashion Design of the Arnhem School of the Arts (ArtEZ) in 2016 and completed her residency at the Jan van Eyck Academy in Maastricht in 2018. There she met Ronald Boer and Jonmar van Vlijmen after which they started their collaboration.
