This implies that we had to take into account a great many uncertainties when developing these recommendations. One of the ways to do this is to work with scenarios, whether or not supported by modelling work. This means each of the recommendations on the following pages is substantiated by the insights arising from this scenario work. Furthermore, we involved a diverse group of stakeholders living and/or working in the region in this exploration ... : We would therefore like to expressly thank all the stakeholders and experts who have made us familiar with the Oudland Polder in recent years, in particular the staff at the VLM. We also extend our sincere thanks to everyone who took part in one of the workshops, gave feedback on publications or took the time to work with us on the various scenarios referred to in this publication. ...
