Natural hazards, unnatural disasters: the economics of effective prevention.

Abstract

This memo introduces a report that you may find useful and interesting. Focusing on preventing death and destruction from “natural” disasters, it concludes that governments can appreciably increase prevention. The good news is that prevention is often cost-effective. It requires many actions, and some important ones are under government control. But they are not always obvious. Improving the public delivery of some services, like reliable public transport, allows people to move from unsafe areas close to work to safer locations. Reducing deforestation prevents heavy rains from washing mud, rock, and debris into populated areas. This report suggests how such measures and related spending could be identifi ed and made effective.
