THE RISE OF “WHOLE COMMUNITY RESPONSE” TO DISASTERS: In all-hands-on-deck response to Harvey, lessons learned from earlier storms.

Ahead of the storm, there were questions about whether Texas-style self-reliance or a centralized, civil-defense-era response from the federal government should govern. But as an all-hands-on-deck response to historic floods has unfolded, the all-of-the-above support exemplifies something new, disaster experts say: a template for what the nation’s top emergency managers call “whole-community” response. It’s a dramatic shift since hurricane Katrina in how the United States prepares for natural disasters, encompassing everything from agency leadership in Washington to Mr. Sherrod and his sturdy compatriots from East Texas. . . .

During Katrina, some rescuers literally had to sneak into the city to help. In Houston, the Cajun Navy has been part of a massive volunteer response, encouraged by officials. Twelve thousand National Guardsman also are being deployed, the government announced Monday.

The Cajun Navy represents both literally and figuratively the importance of neighborhood social networks – what researchers call “social capital” – that has become increasingly part of national response to disaster.

Well, I said it was a good idea.
