Urban planners and policymakers face increasing challenges as climate change intensifies the risk of extreme weather events, requiring a dual focus on mitigation and adaptation strategies in urban governance, according to Li Xiaofang, former director of the China Academy of Urban Planning and Design.

In a recent discussion, Li emphasized that climate mitigation efforts aim to reduce greenhouse gas emissions through green and low-carbon initiatives, thereby slowing global warming. However, she noted that even if net-zero carbon emissions are achieved, existing climate disruptions may continue, necessitating robust climate adaptation measures. Unlike mitigation—which provides broad, universal benefits by cutting emissions globally—adaptation is inherently localized, varying significantly depending on the specific vulnerabilities and circumstances of cities and countries.

This localization of climate adaptation presents challenges in establishing standardized indicators or benchmarks, Li explained. The impact of the same extreme weather event may differ widely between regions, making tailored, context-specific solutions critical.

Financially, climate adaptation efforts primarily rely on public funding, though Li highlighted the importance of fostering coordinated innovation in policy areas such as fiscal management, finance, credit, and taxation to encourage social capital participation. Establishing integrated institutional frameworks will be crucial to mobilizing resources and managing risks effectively.

Li also pointed to contrasts between traditional villages and historic districts, which often developed sophisticated, localized disaster prevention systems over centuries by avoiding high-risk locations, and rapidly developed urban areas. The latter, frequently constructed without historical resilience frameworks, tend to be more susceptible to climate hazards.

Additionally, she stressed the significance of watershed-level coordination for urban flood and drainage management. In some cases, disparities in drainage standards between upstream and downstream areas can exacerbate flooding downstream, as rapid water runoff upstream increases pressure on lower-lying regions. Coordinated regulation of drainage rates across entire watersheds, including possible upstream restrictions, is necessary to share risks and reduce disaster exposure throughout the system.

Li’s insights underscore the complex and multi-dimensional nature of urban climate governance, highlighting the need for integrated, locally adapted solutions alongside global mitigation efforts to protect cities from escalating climate threats.
