The terrorist attacks of September 11, 2001 (9/11) on the United States prompted a rethinking of how the United States prepares for disasters. Federal policy documents written since 9/11 have stressed that the private and public sectors share equal responsibility for the security of the nation's critical infrastructure and key assets. Private sector entities have a role in the safety, security, and resilience of the communities in which they operate. Incentivizing the private sector to expend resources on community efforts remains challenging. Disasters in the United States since 9/11 (e.g., Hurricane Katrina in 2005) indicate that the nation has not yet been successful in making its communities resilient to disaster. In this book, the National Research Council assesses the current states of the art and practice in private-public sector collaboration dedicated to strengthening community disaster resilience.
