Two simple Methods for Erosion Control (video)

Here's a quick video I made about stopping soil erosion.  It includes two simple methods and the three key concepts preventing erosion.  

Filmed at Wubu, Model for Rural Development near Livingston, Guatemala.  Starring Pablito, a local worker here.  See a more recent and much larger project at the same site: Wübu Agroforestry - Corn and Contour lines in Tropical Guatemala.
