Abstract
Freshwater scarcity in the IJsselmeer Region is intensifying due to the dual pressures of climate change and socio-economic development. Rising temperatures, salinisation, and increased water demand have exposed the limitations of the current water system. This research addresses the urgent need for adaptive spatial planning by developing a Dynamic Spatial Adaptive Pathway (DSAP) methodology to expand freshwater buffer capacity through water circularity. The approach combines regional planning frameworks with design-based spatial strategies and consists of six steps, grouped under four phases: system framing, vision learning, decision supporting, and strategy implementing. The methodology is applied to the Northwest Overijssel region, a key transitional area facing both ecological sensitivity and human water demands. By integrating scenarios based on Delta planning and water policy, the study identifies spatial typologies and sectoral tipping points, enabling phased design
responses across different future trajectories. This adaptive approach bridges policy and design, allowing for the monitoring of system changes and timely responses through spatial interventions. The methodology not only responds to uncertainties in water supply but also enables co-benefits for ecological quality and long-term resilience. Through a combination
of scenario planning, stakeholder engagement, and adaptive design, this research offers a replicable planning framework for other regions within the Dutch Delta context and provides strategic insight for linking high-level water policy with grounded spatial implementation.
