The taskings set out in this Delta Plan pertain to the issues of waterlogging, heat stress, drought, and urban flooding. These issues already have a noticeable impact: extreme heat is already taking a death-toll, and extreme rainfall and drought are already causing major damage. However, the four issues do not pose a threat everywhere, nor are they equally important everywhere.
Urban flooding: insofar as measures concern adaptations in spatial design to reduce the impact of any urban flooding (second layer, multi-layer flood risk management).
The Delta Decision on Spatial Adaptation has introduced the “Analysis, Ambition, Action” method in the purview of a structured approach to the four issues. In order to effectively tackle undesirable effects, we must first map out the challenges in a specific area (“Analysis”). This produces differences between urban and rural areas, between built-up and undeveloped areas, between elevated and low-lying parts of the country, between sandy soils and peaty areas. The next step involves the formulation and embedding of goals (“Ambition”). These goals will subsequently be substantiated through measures (“Action”).
In recent years, government authorities and other parties have already embarked on the “Analysis, Ambition, Action” process. The progress made differs from one theme to the next. The results constitute the point of departure for this Delta Plan.
