Vetiver System for Extreme Slope Stabilization - Part 2

Sunday, March 21, 2010

Following part 1 above, here are two images of the Congo Brazzaville work 12 months after planting.  One of the problems is the use of the gully as a rubbish dump, mass dumping will bury the Vetiver!  Community awareness work is needed here!

More information on the technique and on how to further improve the application is available from Alain Ndona

Note that the vetiver that was planted on the gully bottom looks to have been buried in mud.  I believe the soil in the bags was from the site with no additives, and there were no temporary "nails" holding the bags in place, whilst the vetiver grew.  If this were to be a problem it might be resolved by driving bamboo or wooden stakes through the bags.
