Delta decisions

Delta Decision on Spatial Adaptation

• Issues : pluvial flooding, drought, heat stress
• Netherlands climate proof and water robust in 2050
• In 2020 municipalities, infra managers (etc) have

detailed plans

• By 2050 vital infrastructure and vulnerable functions are

resistant to flooding, heatstress etc

Rijkswaterstaat 4 Lege presentatie

Vital infrastructure: replacement and renovation

• f hydraulic structures as window of opportunity

This task demands:

• End of lif time estimations (technical and functional)

(tipping point analysis for flood risk, shipping, fresh water supply, salinisation etc)

• Looking for new functionality and capturing value:

investment strategies; adaptation pathways and real in options (object and system)

• Construction renewal: flexibility in design,

regimentation, modularisation, new materials, CO2 footprint, energy etc.

The policies right, making infrastructure investment climate resilient?

In the Netherlands delta decision on spatial adaptation; Different levers?

• Flood risk management national scale: national standards & program
• (Pluvial) Flood risk management regional and local scale: spatial

planning retention areas, assurance

• Heats stress, drought will hamper agriculture, shipping, nature

conservation.

• Infrastructure: pressure on business continuity/availibility/reliability
• Asset managers: ‘standard’ to what costs? Risk approach to

performance over time

• Implementation in scopes of (re-)designing, construction, renovation,

replacement, maintenance of infrastructure etc.
