CHN-HY03 In south China there has been massive infrastructure development over the past 15 years. As a result 80% of the areas sediment flows are estimated to come from sites like this. Vetiver was introduced for highway stabilization in 1997. Here a very steep fill is being plantewd with vetiver in Jiangxi Province
