Delivering impact

We are constantly challenging ourselves to deliver impact. We push ourselves to create high quality work and to make an impact on society by drawing on the power of our knowledge. For us, this means creating and applying sound knowledge on water and the subsurface, so that we can keep our densely populated deltas habitable, sustainable, and safe - both now and in the future, in the Netherlands and throughout the world. The challenges facing society are huge and complex, and they require an integrated, systemic approach in which we transform in-depth knowledge into comprehensive insights.

We are eager to continue co-creating with others, so that we can make a positive contribution to innovative solutions that improve life in deltas. Collaborating with our partners, other knowledge organisations, and clients. We will also continue our dialogue with you on developing a relevant knowledge base, addressing the right questions, and creating a positive societal impact through an inclusive knowledge uptake.


Delivering on impact also means communicating more explicitly. For instance, on the development of impact pathways to show the concrete steps in working towards impact. We are continuously learning how we can do better and invite you to continue the dialogue and learn with us.


This is our second Impact Report. In it we present 19 stories that illustrate how our activities help us make an impact. We have linked our mission-driven activities to the Sustainable Development Goals and the Dutch national missions, so that we can demonstrate our targeted contribution.
