Disasters like earthquakes are known as focusing events—sudden calamities that cause both citizens and policymakers to pay more attention to a public problem and often to press for solutions. This book, the first comprehensive analysis of these dramatic events, explains how and why some public disasters change political agendas and, ultimately, public policies.

Thomas A. Birkland explores important successes and failures in the policy process by analyzing the political outcomes of four types of events: earthquakes, hurricanes, oil spills, and nuclear accidents. Using this empirical data to go beyond an intuitive understanding of focusing events, he presents a theory of where and when these events will gain attention and how they trigger political reactions. Birkland concludes that different types of disasters result in different kinds of agenda politics. Public outrage over the highly visible damage caused by the Exxon Valdez oil spill, for example, ended a fourteen-year logjam holding back Congressional legislation to regulate oil spill cleanups. On the other hand, the intangible effects of Three Mile Island had less concrete results in a political arena that was already highly polarized.

Integrating a variety of theories on the policy process, including agenda setting, policy communities, advocacy coalitions, the political aspects of the news media, and the use of symbols in political debate, Birkland illuminates the dynamics of event-driven policy activity. As the first extensive study of its kind, this book offers new insights into the policy process.

Even before the wreckage of a disaster is cleared, one question is foremost in the minds of the public: "What can be done to prevent this from happening again?" Today, news media and policymakers often invoke the "lessons of September 11" and the "lessons of Hurricane Katrina." Certainly, these unexpected events heightened awareness about problems that might have contributed to or worsened the disasters, particularly about gaps in preparation. Inquiries and investigations are made that claim that "lessons" were "learned" from a disaster, leading us to assume that we will be more ready the next time a similar threat looms, and that our government will put in place measures to protect us.

In Lessons of Disaster, Thomas Birkland takes a critical look at this assumption. We know that disasters play a role in setting policy agendas—in getting policymakers to think about problems—but does our government always take the next step and enact new legislation or regulations? To determine when and how a catastrophic event serves as a catalyst for true policy change, the author examines four categories of disasters: aviation security, homeland security, earthquakes, and hurricanes. He explores lessons learned from each, focusing on three types of policy change: change in the larger social construction of the issues surrounding the disaster; instrumental change, in which laws and regulations are made; and political change, in which alliances are created and shifted. Birkland argues that the type of disaster affects the types of lessons learned from it, and that certain conditions are necessary to translate awareness into new policy, including media attention, salience for a large portion of the public, the existence of advocacy groups for the issue, and the preexistence of policy ideas that can be drawn upon.

This timely study concludes with a discussion of the interplay of multiple disasters, focusing on the initial government response to Hurricane Katrina and the negative effect the September 11 catastrophe seems to have had on reaction to that tragedy.
