Environmental risk management with the aid of city emergency response system in Nanning City

Environmental risk management (ERM) is updated on the city emergency response system (CERC) in Nanning City, China. The technical routine developed better support effective urban ERM in the Nanning CERC. Started from identification of risk sources, programs of sources monitoring, risk prediction and early warning, treatment and disposal, and management with update were discussed. Furthermore, environmental risks posed by the China-ASEAN (Association of Southeast Asian Nations) Expo, an international trade fair were evaluated. The inverse searching technique was used to identify the hazardous sources that can cause risks at the Expo. The paradigm of ERA facilitates investigating the connections between hazard sources and adverse effects for people involved in the Expo. Sensitivity amongst people involved during the Expo was determined according to human oriented characteristics. Temporal and spatial sensitivities of the Expo related to the environmental risks were defined. The developed methodology has successfully safeguarded the China-ASEAN Expo from 2004 to 2008. This work highlights major steps in the procedure for update on the CERC with ERM, which provides a demonstration case for integrating urban emergency response and environmental management with functional enhancement.
