The theme of the 2021 Conference is “Smart Surveyors for Land and Water Management“. How to build and manage a densely populated coastal country with a land area of which nearly half is below sea level? We, the Dutch know how to do just that and have done so for centuries. The role of surveyors in this endeavour has been crucial. And their role is even more crucial today when we have to protect our country against the impact of climate change causing sea level rise.
