Looks a lot like GIS to me. But what's this? Not using a broad tract system to generate region averages, but instead more detailed and neighborhood specific system? These maps only show racial segregation, but its a promising basis for the improvements for which Davidson advocates in EJ analysis.

Here's Portland's map: http://www.flickr.com/photos/walkingsf/4982015862/in/set-72157624812674967/ This is an important and significant perspective. Compared to other cities, we're not working with a lot when we talk about diversity and segregation in regards to environmental justice. Comparing our EJ mapping to EJ mapping in cities with much more significant segregation would be interesting! (Who wants to do some more GIS mapping for fun over fall break??)

This (http://www.radicalcartography.net/index.html?chicagodots) is Bill Rankin's website, the cartographer who first produced one of these detailed maps in 2009 and inspired Eric Fischer to produce all the others (found here: http://www.flickr.com/photos/walkingsf/sets/72157624812674967/with/4981417821/). Check out the downloadable files on Rankin's website (there's one for race and one for income); he includes includes a traditional GIS map of the same data for comparison. (I recommend saving them to your computer and viewing them at a smaller scale to see the patterns more easily.) This is from his website: "There are indeed areas where changes take place at very precise boundaries... But transitions also take place through gradients and gaps as well, especially in the northwest and southeast. Using graphic conventions which allow these other possibilities to appear takes much more data, and requires more nuance in the way we talk about urban geography, but a cartography without boundaries can also make simplistic policy or urban design more difficult - in a good way."

Students in ENVS 220 recently learned how to georeference historical air photography in ArcMap; well, here are some other ways to do it with maps for eventual input into GoogleEarth!

Map-based interface comparing human quality of life (primarily related to health, education, and income, but including other measures as well) in different parts of the US. Turns out, surprise surprise, that there are some huge differences from place to place, suggesting the necessity of situated research to explain these differences.

Wisconsin is one of two states to have a "State Cartographer," and man does he have some interesting stuff to say. The interview here speaks to GIS software and technology, but also the broader perspectives on exactly what it is a map does, and how it does it. Particularly interesting when he speaks about values - every map has them, he says, they are not neutral parties. Is this true for other tools we have for conveying information?

An example of GIS in real life! Danielson Castillo is using geographic information system (GIS) mapping to layer several sets of data on a computerized map. The depth and breadth of the mapping project, completed last month, is unheard of on a community level in Minnesota. The project was funded with a $20,000 grant from the McKnight Foundation, but Danielson Castillo and Matson believe it's a tool that will become increasingly common and affordable for community organizations. Danielson Castillo already has given demonstrations of his GIS map to a number of community organizers.

"About 80% of the world's population lives in areas where the fresh water supply is not secure, according to a new global analysis." This article addresses a new study published in "Nature" that is looking at patterns of global water stress. It weighs the benefits of the western approach (damns, canals, etc...) against more integrated, "natural" approaches such as preserving wetlands and floodplains. The centerpiece of the study is a great example of GIS mapping on a global scale.

"... researchers were especially surprised to find that wealthy nations were no better at safeguarding their rivers than developing nations." GIS mapping used here too. After the Willamette River cleanup this past Saturday, this topic has been on my mind. I think we really need to address the chemicals we're dumping into our water, and this doesnt just mean the typical concerns around oil and extremely toxic compounds. We have a mentality that water is only here for us to use to get rid of our waste. We emphasize the importance of "clean water" for people's health because we use clean water for cleaning things, but we forget that even though we're clean, the water's not anymore. And the truth is, water does a lot more than function as a human waste disposal. We should know better than to think that we wont have to deal with the effects of the chemicals in our shampoos, toothpastes, and agricultural chemicals once the drain/rain takes them away. It just takes the effects a little longer to cycle back around, but clearly, they have.

Ninety five percent of the corn gene has been successfully mapped out. Scientists claim that with this genetic information, they will be able to "develop new maize varieties that withstand prolonged heat and drought, use nutrients such a nitrogen more efficiently, or pack more nutrition per kernel."

This article highlights a neat project that does two things to some branches of modern macroeconomic study. First, it complicates some basic economic ideas, moving beyond GDP to a range of other valuable metrics for measuring economic success (including, for example, diversity and resilience). Second, it takes those more complex approaches to economic systems and uses neat graphical interfaces and visual media as a means of presenting them effective. The images shown as samples are colorful, visually pleasing, and they convey a lot of information. As one author points out: "Our brains have been processing letters, symbols, and numbers for the last 10,000 years, but as animals, our ancestors have, for millions of years, been developing the eyes and the visual cortex of the brain. The eyes are able to process visualized information much more quickly then they can process symbols. We tried to express very complex information in a way as visual possible, so that we can use the most efficient parts of the brain as opposed to the inefficient. A computer can beat a human at chess, at calculations. But a computer has enormous difficulty recognizing a face. A human can do that without thinking." Couldn't help but think of the posters, maps, graphs, websites, and other forms of sharing data that are used through environmental studies. It ties back to another thought I have that perhaps the messenger (or medium) often matters more than the message, at least in terms of how it is received.
