A realistic map of Louisiana

Walkable, inhabitable land area of Louisiana

Southern Louisiana, like the Netherlands, is inhabitable because of the actions of humankind.  Just as the Dutch live behind their ocean dikes, Louisianans live behind their river levees.

Inadequate maintenance of the levees by the U.S. Army Corps of Engineers made the Hurricane Katrina disaster of 2005 worse than it might have been.

There is a good side to this.  Sinking replaces dry land with swamps and wetlands.  Although swamps and wetlands are not walkable or inhabitable, they provide a buffer against ocean flooding by absorbing the water.

It’s complicated.  Global climate change will generate more floods, and make things even more complicated.

Tragedy and hope in Louisiana floods

During the past week or so, I’ve been reading about the disastrous floods in south Louisiana, which, according to recent estimates, have left tens of thousands of families homeless and destitute.

Middle-class people, living in places that have never been flooded before, have lose everything and depend for food and shelter on the charity of strangers.

But it is a story not only of disaster, but of hope.  Rod Dreher, a writer for the American Conservative, who lives in that region, tells on his blog how everyone in the community—white, black and Asian, middle-class and poor, Republican and Democrat—have come together to help in the face of the disaster.

Almost everybody in that part of the world owns a boat, and a so-called “Cajun Navy” has rescued many stranded elderly and sick people who otherwise would have lost their lives as well as their property.

The local churches, of many denominations, have been the main organizers of rescue and relief—which is not to say that unbelievers haven’t helped out or that the federal and state governments haven’t done their jobs.

Many people, including Dreher and his wife, have taken strangers into their homes.  Also—

My daughter spent the day at Amite Baptist church preparing meals for people who have no home, while volunteer crews tore out the water-logged carpet and pews.

My boys were part of a crew from their school who have been going out to muck houses of school families who were flooded out. They had to boat in to this one elderly woman’s house (her grandchild goes to the boys’ school) to take out drywall, pull up carpet and floorboards, and suchlike — this, in 91 degree heat, in humidity over 90 percent. While they were there, the elderly lady collapsed with a heat stroke inside the house. My older son called 911, and the crew boated across the water to pick up the paramedics and take them to the house while the others used ice from their coolers to try to keep her alive. They boated her and the paramedics back across the water to the ambulance. The lady made it, thank God, but it was a very close call.

All the boys working on the mucking crew who saved her life learned a valuable lesson today. My boys came home in clothes stinking of sewage water, with aching muscles and stories to tell.

And here’s something from the Facebook page of one of Dreher’s friends.
