Comprehensive disposal plan design & polymerization disaster risk assessment based on information diffusion...

Area of Science:

• Environmental Science
• Disaster Management
• Risk Assessment

Background:

• Villages and towns along the Fujiang River in Sichuan experienced significant data loss due to combined earthquake and flood disasters.
• These natural disasters severely impacted agricultural production and the livelihoods of local farmers.
• The region faced substantial integrated risk losses, averaging 5.758 million Yuan annually.

Purpose of the Study:

• To evaluate the process and extent of damage to farmers' production and lives caused by natural disasters.
• To assess the effectiveness of intervention strategies in mitigating disaster impacts and enhancing resilience.

Main Methods:

• Utilized intelligence internet data collection to gather information on damaged families.
• Employed information diffusion technology to evaluate the impact of disasters on production and life.
• Implemented comprehensive suppression and blocking interventions, coupled with watershed management and post-disaster reconstruction.

Main Results:

• The integrated risk from floods and earthquakes resulted in substantial annual losses for the affected communities.
• Over the past decades, the implemented strategies have led to a gradual decrease in disaster frequency and severity.
• Infrastructure, including rivers and diversion canals, demonstrated enhanced resilience against integrated disasters.

Conclusions:

• Comprehensive disaster prevention and control strategies, integrating watershed management and reconstruction, are highly effective.
• The applied methods have significantly improved the region's capacity to withstand and recover from natural disasters.
• The study highlights the remarkable success of the designed scheme in mitigating disaster impacts and bolstering community resilience.
