Alluvial Fans

Alluvial Fans | Lorraine's Environmental Change &  Management | Scoop.it
When streams emerge from mountains, they often spread out and deposit sediment in a distinctive pattern known as an alluvial fan.

Gene Gagne's curator insight, November 18, 2015 3:27 PM

These fans are like a good Delta. People live between the mountains and the desert. Water runs down the mountains making a fan to where now a little distance away farms are produced and good vegetation.

Benjamin Jackson's curator insight, December 14, 2015 11:29 AM

these are the fascinating geographic anomalies. its amazing the civilizations that rise up on earth, but are totally alien to us, even in the age of instant communication.

Nicholas A. Whitmore's curator insight, December 17, 2015 12:02 PM

An interesting little piece of Kazakhstan geography here. I find it fascinating that not only are these unique to deserts due to low vegetation but that they become perfect for agriculture (an irony of sorts I suppose). I also rather enjoy how the agricultural areas are spread out like a fan like the water runoff from the mountain. One key feature I didn't notice until I read it was the railroad that goes right through the fields to reach the town on the outskirts of the Alluvial fan. I am particularly curious to how many areas actually use this to make the desert a hospitable place for habitation (since it is usually a bad idea due to lack of water and food). It would also have been more interesting if the culture of the people who inhabit these places was discussed since it would likely be different in other places since they are only relying on 1 main water source. Geographically and historically I can imagine that places like this would have also been key strategic locations especially when traversing the arid areas.

Coast Lines

Coast Lines | Lorraine's Environmental Change &  Management | Scoop.it
In the next century, sea levels are predicted to rise at unprecedented rates, causing flooding around the world, from the islands of Malaysia and the canals of Venice to the coasts of Florida and California. These rising water levels pose serious challenges to all aspects of coastal existence—chiefly economic, residential, and environmental—as well as to the cartographic definition and mapping of coasts. It is this facet of coastal life that Mark Monmonier tackles in Coast Lines. Setting sail on a journey across shifting landscapes, cartographic technology, and climate change, Monmonier reveals that coastlines are as much a set of ideas, assumptions, and societal beliefs as they are solid black lines on maps.

How Geospatial Analytics Are Changing Habitat Conservation

"The BirdReturns program is an effort to provide 'pop-up habitats' for some of the millions of shorebirds, such as sandpipers and plovers that migrate along the Pacific Flyway, a route that spans from Alaska to South America. Birds flying on this journey seek out the increasingly rare wetlands teeming with tasty insects to fuel their long-distance flights.  Over the last century, California's Central Valley has lost 95% of the wetlands habitat to development, agriculture, and other land use changes. As a solution, scientists use big data, binoculars, and rice paddies."

Seth Dixon's curator insight, June 17, 4:35 PM

This project combines data from satellite imagery to map surface water in California's Central Valley, and individual bird observations to select locations that can be temporarily converted into wetlands to aid the migratory birds (for more information than the video provides about this project, read this article). 

 

This is a great example of using both 'big' geospatial data as represented by the satellite imagery and combining it with field data and actual observations to make the world a better place.  We need more decision makers that can think spatially and use geographic skills.
