Author of Mapping the Nation, Susan Schulten explains how western expansion failed to recognize the basic physical geographic reality of the United States--that the west is much drier than the east.  Given that much of the west, especially California, is in the midst of a severe drought, this article serves as a reminder to recognize that localized understandings of human and environmental actions are necessary.  Do you know what watershed you live in?  How does and should that impact us?

We are very proud in France thinking we created the watershed approach with the 1964' water law, present basis for EU's water framework directive. Now, I would say that John W Powell is the true creator of watershed management. It's a blow to French pride...

A useful discussion on limits of the planet

Seth Dixon's curator insight, February 11, 2013 5:23 AM

This is an interesting article discussing the limits that the Earth's physical systems have and the importance not exceeding any tipping point that could destabilize the planet if we "overstrech the springs."

Angus Henderson's curator insight, February 11, 2013 8:49 AM

An interesting counter-balance to the work of the Planetary Boundaries group.

Full Extent of Africa’s Groundwater Resources Visualized for the First Time

Full Extent of Africa’s Groundwater Resources Visualized for the First Time | Human Geography Too | Scoop.it

Until now, there has been a lack of solid, comprehensive spatial data about African groundwater resources.  Researchers have now done so.  For a more academic article on the subject, here are their findings in Environmental Research Letters.
