This is TBS. I'm the World. I'm John Batchel with Professor Beth Tellman, University of Arizona Geography Department.

Also the chief science officer and co-founder of Cloud District, publishing in Nature magazine, the premier peer-reviewed magazine for science in Europe, matching science here,

about a database compiled using satellites, NASA satellites, to point to where the flooding has been,

the early years of the 21st century, where the people are, the movement of people,

growth of people in the floodplains. And what all that adds up to is, for example, I

learn in the summary of the article, this is a very useful item for financial speculation about municipal bonds, what is and what is not desirable for insurance, for areas that have experienced floods or might experience floods again.

A hundred-year flood means you have 1% every year.

And as we note recently, there are a whole lot of one percenters coming in. So, Professor,

if I go to the summary correctly, Asia dominates the story. Three hundred and ninety-eight of the

913, 52 in China, 85 in India. The ones in China seem especially damaging.

Did you pick that up with your satellite images?

Yes.

There are a lot of floods that were mapping in Asia, generally, southern Asia and Southeast

Asia specifically, and some of the largest growth we've seen in people building and moving into floodplains has been in these regions.

So you can see, for example, if you are in the paper on figure four, a lot of these countries on figure four A that you'll see

lighting up in orange and red. Those are the countries where we've seen a lot of growth in flood

planes in about the past 20 years. But what's even more concerning is figure 4B. These are

climate change projections for 2030. You see even more countries in Asia

start to light up in these yellow and orange colors. And that indicates that climate change

will significantly increase flood exposure in this region. However, Asia is not the only suspect

for having to make adjustments, financial adjustments, insurance,

population. Really, if you live in a floodplain, bad things are going to happen eventually.
