Final answer:
To overcome the risk of flooding, the cities of Ascona and Locarno implement adaptation strategies such as seawalls, levees, and wetlands preservation.
Step-by-step explanation:
The cities of Ascona and Locarno, built on a delta in the Alps, face the significant constraint of potential flooding from nearby water bodies. To overcome this, these cities, similar to others built in low-lying coastal or flood-prone areas, must adopt various adaptation strategies. These can include the construction of seawalls and levees to prevent flooding from coastal waters, as well as the preservation of wetlands that act as natural barriers against storm surges. While historical approaches in managing water resources have been vital, like the ones employed by Milan using hydrological projects to bind regions together, modern approaches need to take into account the increased risks due to climate change and higher instances of extreme weather events. In areas with complex geography and frequent natural hazards, like earthquakes, building designs have been adapted to suit the unique environmental conditions, ensuring safety and resilience in the face of natural disasters.
