Soil Degradation - Excellent video for the socio economic impacts. 

I wanted to alert you to an excellent source that would fall directly under the new IB syllabus for Patterns in Env Quality and Sustainability.  When asking for a case study on sustainable management strategies, I'm using China's Loess Plateau.  There is an excellent film (on youtube and on the website) of a watershed rehabilitation project that has been incredibly successful.  This case study connects concepts of soil erosion, watersheds, climate change, and the social/econ and environmental consequences of this World Bank/Chinese gov't project.
