Some Observations• Recent review of Marine Nature Projects• Marine Works Practice:
– Regional planning: Long-lasting procedures – Design: Reactive with focus on minimising effects– Realization: mitigating measures poorly substantiated
World Wide Water Engineering • Large part of world population lives and works in
coastal, delta and river areas• Autonomous developments such as climate change and
sea level rise • Needed: regional development in a way that allow both
economy and nature to flourish in a sustainable way
Something already changed• More integration and participation to smoothen processes• More system-based approach in design• New developments in eco-engineering, because:
– Processes and projects can go faster– Safer and more natural living environment– Room for entrepreneurship
• Applied innovation programme “Building with Nature”
Programme Building with Nature• Budget over 30 MEUR (4 years programme)• Consortium representing broad range of organisations
and disciplines (public and private)• Network for exchange of knowledge and expertise• Jointly developing knowledge and solutions for concrete
pilots (learning from doing)
Ecodynamic Design Principles• Designing and building with and from nature• Focus on ecological chances (dynamic not static)• Based on sound system knowledge• In short: use nature as “dynamic engine”• Ecologists and hydraulic engineers work together, in all
project phases
Ecodynamic Design Principles (cont.)Knowledge break-through - natural system:• From status quo towards dynamics• From descriptive towards predictive• From species towards systems• From false securities towards living with uncertainties
Ecodynamic Design Principles (cont.)Knowledge break-through - technological system:• From engineering thinking towards integral thinking• From mitigating negative effects towards adaptation to
the natural system• From reactive towards pro-active
Ecodynamic Design Principles (cont.)Knowledge break-through - governance system:• From controlling towards managing• From threats towards chances• From closed government domination towards open
multi-actor processes
