This week: Thailand’s battle to avoid future flooding in Bangkok, the recovery along the Missouri, the effect of dams, Hickenlooper on the Colorado River, and a compilation of useful mapping and imagery posts from the ArcGIS blog.
For residents of Thailand’s capital, the economic and political center of the country, the timetable for change is shrinking. Scientists worry that Bangkok is slowly sinking and the low-lying city is threatened by global warming that could raise sea levels, causing more frequent flooding.
The World Bank warns that Bangkok’s flood risk will rise four-fold in coming decades, worrying many that the 2011 floods will not likely be the last.

“In some cases we had sand drifts 15 feet deep or more,” said John Wilson, an extension educator for the University of Nebraska-Lincoln, who added that in other fields the problem is massive erosion. “Some of them, they’re just getting abandoned. It costs more than the land is worth to reclaim it.”
While the U.S. government has resisted taking down any major hydroelectric dam along the Columbia system, political pressure is mounting. No doubt all concerned parties will be paying close attention to the ecosystem and salmon recovery on the Elwha as it unfolds over the next few decades.
Denver’s done better than most U.S. cities, with residents reducing use by 20 percent since 2002 to 160 gallons a day, but "we can make dramatic additional efforts," Hickenlooper said.
"Our self-discipline in the amount of water we use is going to be the foundation of everything we will do," he said.
In this blog entry, I point out a number of posts that have been published on the Imagery blog that may be of interest to the Mapping Community. And conversely I note a number of Mapping blog posts that may be useful to the Imagery community. These blog posts will now appear if you search in either the Imagery or the Mapping category.
