Crowdsourcing land cover data

You know how we’ve occasionally wondered out loud here whether it might be possible to crowdsource information on the geographic distribution of a crop (or indeed crop wild relatives), or even of threats to crop diversity. Well, some clever folks have gone out there and are actually doing it, for global land cover. And making it fun to boot. Now we have no excuse.

New Plant Hardiness Zone Map ready for prime time

There’s a USDA media blitz on about the new Plant Hardiness Zone Map for the United States.

The 2012 USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which plants are most likely to thrive at a location. The map is based on the average annual minimum winter temperature, divided into 10-degree F zones.

You can read the paper. You can read the press coverage. And you can watch the video.

The good news for America’s 80 million gardeners is that for the first time the map is available in an online interactive version, and is a lot more accurate. The bad news is that things are getting hotter, and many of those gardeners are going to have to rethink their choices:

The new PHZM is generally one half-zone warmer than the previous PHZM throughout much of the United States, as a result of a more recent averaging period (1974–1986 vs. 1976–2005).

But then we knew that. As far as I can see, you can’t compare the new version with the old online, side by side kind of thing. That would be one powerful climate change advocacy tool, wouldn’t it. Gardeners don’t like to be messed with, in my experience.

Kermit sings the malnutrition blues

When you start really looking out for something, you quickly get to wondering how you could possibly have missed it all before. Case in point: maps of the USA which hint at “a complex association where interactions between a variety of factors could produce reinforcing effects.” That’s in the words of an Annals of Botany Google+ pointer to a recent post of ours here which included maps of obesity and food insecurity and mused vaguely about the coolness of mashups.

After that, of course I started seeing such maps everywhere. Of renewable resources, including biomass. Of landuse. Of poverty. Of, errr, the names of soft drinks.

Some regions jump up at you during the even briefest of looks at the maps of poverty, obesity and food insecurity. Like the Mississippi Valley, for instance. So it is at least somewhat reassuring that other people have noticed that too, and are doing something about it. Even doing multiple things about it, in fact. USDA probably didn’t need fancy maps to identify this particular nexus of deprivation, but maybe there are others that are not so obvious, and which an in-depth perusal of these maps will bring to light. Along with, hopefully, some possible solutions. Even if they are only farmers markets.

But to end on a lighter note, this region is not just known for poverty and malnutrition. The blues came from there, of course, but also, ahem, Kermit the Frog. In fact, there’s a connection between our green friend and agriculture. I am reliably informed that Jim Henson’s father was superintendent of the USDA-ARS research station in Stoneville, MS and worked closely with researchers there. Perhaps Kermit should be asked to spread the nutrition and exercise message around his old hopping grounds? I can’t think of a more suitable role model.
