Dalian

China

Dalian is projected to face significant climate risks due to heavy rainfall events and frequent heavy precipitation. These hazards threaten infrastructure, public health, and ecosystems as flooding becomes a persistent issue. The increasing intensity of rainfall is expected to lead to severe flooding that could impact homes, businesses, and transport networks, alongside enhanced water runoff causing soil erosion and compromising water quality. Agricultural productivity in surrounding areas may also suffer from these dynamics. As climate projections indicate that these extreme weather events will intensify, it is crucial for Dalian to consider adaptive measures for resilience. However, technology-enabled solutions for climate resilience have not yet been documented for this city, which poses additional challenges in effectively addressing and mitigating these vulnerabilities. The situation calls for urgent attention to bolster the city’s capacity to face these climatic challenges.
