The geographical features of Vancouver determine its vulnerability: the Fraser River Delta has a low-lying terrain, with most areas being below sea leveltwoRice;two thousand and one hundredExpected sea level rise before the yearoneRice, combined with storm surges, can cause a sudden increase in water levelthreeAbove meters. Traditional“Hard confrontation "The engineering thinking seems inadequate in the face of such complex risks. Based on this, VancouverBreakthrough“Either this or that "The binary thinking,Built a set“natural-Engineering "classificationCollaborative defense system.

Vancouver

The first line of defense: the natural barrier of the ecosystem.Vancouver deeply recognizes that a healthy ecosystem is the most sustainable and powerful first line of defense against disasters. Therefore, the restoration and construction of ecological wetlands and forests are placed at the core——They are not only home to biodiversity, but also natural to cities“sponge”give“Carbon Pool”By implementing both the Urban Forest Strategy and the National Carbon Sequestration Plan, Vancouver aims totwo thousand and fiftyIncrease the urban canopy coverage to22%Realize annual carbon sequestrationtwenty-one thousandTon. By planting local vegetation and constructing ecological revetments, the wetland's ability to absorb floods and purify water quality has been significantly improved,not onlyWe have rebuilt vibrant habitats for wildlife and plants,andSystematically enhancing the resilience and carbon sequestration capacity of ecosystems.

Third Line of Defense: Strategic Space Retreat.Strategic space refers to the transitional space between the central city and the coastline.

This one“Breathable coastline”Not only does it effectively weaken the impact of storm surges, but its flood control capacity is also significantly improved.
