Preliminary findings:
The top 3 most Vulnerable provinces were Gansu, Ningxia and Guizhou, which is consistent with the climate capacity discrepancy.
The West regions are more vulnerable than the coastal and East regions in China, since the former ones were more sensitive to climate hazards and socially vulnerable.
CHALLENGES: Geographical unbalance in
climate risks and vulnerability
Increasing wealth and more exposed physical capitals: esp in coastal developed areas
Aging society with more exposure population

Challenges for building resilient cities
Weakness & Strengths of China’s Mega-cities
Financial capacity Technical capacity Engineering infrastructures Institutional capacity Ecological health
Mainstreaming Adaptation and DRR into Urban planning
Challenges: More aging and wealthier cities in future
Disparity in economic and social vulnerability
Consolidating Urbanization with large poverty population

Make city more resilient and low carbon: Integrate adaptation and mitigation into city strategy
Adaptation Reduce the vulnerability: lifeline of city Low carbon adaptation: urban green lands, green power,
environmental infrastructures, etc. Synergy between mitigation and adaptation
Planning • Urban planning: transport, residential settlement• Industry planning: resources dependant sectors• Spatial planning: population and land using
Technology • Green building, smart grid, etc • Adaptive technologies
Management and governance
