Busan

South Korea

Busan is projected to face a future where heavy rainfall events significantly impact its climate stability. The frequency and intensity of these events are expected to increase, posing severe risks of flooding and erosion that could disrupt urban life and infrastructure. Urban runoff may worsen as drainage systems struggle to manage the deluge, heightening the likelihood of urban flooding. These climate hazards threaten not only the city’s physical assets but also economic stability and public health. Vulnerabilities associated with increased heavy rainfall necessitate urgent attention and planning, as climate projections highlight substantial risks for the future. Notably, technology-enabled climate resilience solutions for Busan have not yet been documented, illustrating a critical gap in addressing these growing climate challenges. Immediate action and research are vital to safeguard the city's resilience against these projected climate impacts.
