The document sets out the Netherlands’ second-phase programme (2022–2027) to secure freshwater availability, aiming for nationwide resilience to water shortages by 2050. It prioritises saving, retaining and smarter distribution of water, with a six-point strategy for the main water system (see figure on p.26) and region-specific measures. Investments of around €800 million (including Deltafonds and regional co-financing) target drought, salinity control at key sluices, groundwater buffering, reuse of treated effluent and “Slim Watermanagement”. Governance, knowledge and adaptive planning are embedded, with stress tests (e.g., IJsselmeergebied) informing choices and a route map towards the third phase.
