4. 1. Inland shore concept Flexible water storage with new functions
Inland water storage with
significant water level fluctuation
Room for water storage to prevent flooding and water scarcity
“Water is an opportunity”
New sustainable areas for work and living
Innovative combinations: water storage, food, nature, recreation, living, working
Dynamic landscapes, room for
natural processes, CO2 sink
Opportunities for WFD, Natura2000, new habitats

5. 1. Inland shore concept Pilot Koopmanspolder: Fish, Nature, Landscape

6. 1st polder in Lake IJssel (200 km2) Constructed during 1927-1930
2. Wieringermeer
Pilot Wieringermeer:
Agriculture, Aquaculture,
Recreation
1st polder in Lake IJssel (200 km2)
Constructed during
Land surface ~ 4 m below Lake level
Upward seepage, salt load
After WW-II: food production
Mono-functional: agriculture

7. 2. Wieringermeer Urgency for change? Short term:
Up-scaling: more efficiency, but low job creation
Population aging: youth leaves area
Regional economy not strong
Loss in facilities, decrease in livability
Long term:
Autonomous developments: water level rise, salt load
Climate change: more extreme weather events
Globally: water and food becomes more scare

8. 3. Building pilots Bottom up approach
Food production is starting point
Open process, trust
A concept,
not fixed ideas
Small scale experiments
Extend from there

9. 3. Building pilots Dike pioneers Sun farming Aqua-test ribbon
Agro-recreation

10. 3. Building pilots Climate landscape agriculture – living - economy
Water storage & new economic activities
Protected shoreline: econ. activities
Open water

15. 4. Concluding remarks From theory to practice
Link long term vision to short term objectives.
A good idea is nice, but you need strong partners for action.
Building a good consortium takes time.
Storyline must be simple and easy to understand.
Invest in PR and communication.
Think in opportunities, not in problems.
