Investment in climate-resilient infrastructure: replacement and renovation Maarten van der Vlist Rijkswaterstaat & Next Generation Infrastructures February 24, 2016

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 February 24, 2016 2 Lege presentatie

Vital infrastructure: replacement and renovation of 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. Rijkswaterstaat February 24, 2016 4 Lege presentatie

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. Rijkswaterstaat February 24, 2016 5 Lege presentatie
