IENE has a very broad network of highly motivated and committed professionals who work at the interface of traffic infrastructure and the surrounding nature. Traditionally, ecologists in particular have attended the conference. This edition therefore also deliberately draws attention to the infrastructural side of ecological measures. We would like to focus more on the direct relation between ecological value and design, technical construction and use of materials. This is what ‘crossing borders’ is about: by better understanding those two ‘worlds’ and combining the best characteristics we can create much more efficient and effective measures to strengthen nature and biodiversity.

Eventually, more than 500 measures have been implemented in the Netherlands thanks to the MJPO, ranging from the well-known ecoducts to small fauna tunnels. The results and lessons learned from such a large defragmentation program are shared with the rest of Europe and even the world during IENE2018. We want to bring participants with their different backgrounds and roles together so that they can get to know each other's work. As a researcher, contractor or commissioning party, a professional at a road authority you always work from a different perspective. The Organising Committee feels it is important to get to know each other's perspectives, to explore each other's views. This calls for ‘crossing borders’ and will lead to better collaboration and thus to better projects in the field of infra-nature.

The charts not only show the great variety of the participants and their various backgrounds but also show the possibilities in terms of sharing knowledge and market potential. The Organizing Committee is very happy with this broad range of nationalities and backgrounds and hopes upcoming registrations will make the conference even more richer than it already is. So please forward this and invite all professionals in your network to join us in Eindhoven!
