Long-term study shows impact of humans on land

The image on the left is a computer-generated landscape with the colors indicating the meters of soil lost or deposited in different places at the end of a simulation of 300 years of farming and herding. 

The photos on the right are of modern Mediterranean landscapes. Top is wheat farming in Jordan, middle is an olive grove at the edge of an eroded barranco (ravine) in eastern Spain, the bottom is goat herding in Jordan.Computer simulations help researchers see what works and what doesn't work in the Mediterranean and helps explore future impact of humans

Central Appalachia flatter due to mountaintop mining

Years of blowing away mountain ridges in search of coal and depositing the excess rock in nearby valleys have dramatically flattened the landscape in parts of Central Appalachia. This animation shows an elevation map of West Virginia's Mud River watershed before and after mountaintop mining became widespread. To see the impact on other West Virginia watersheds, visit <a target="_blank"href="http://www.minedwatersheds.com/">http://www.minedwatersheds.com/</a>.Forty years of mountaintop coal mining have made parts of Central Appalachia 60 percent flatter than they were before excavation, says new research by Duke University.
