Vetiver System and Steep Slope Protection - Disaster Mitigation in Brazil

Wednesday, December 1, 2010


TAKE NOTE: Vetiver System is on the move in Brazil and some very big engineering companies are getting involved. I am hoping that Brazil may be a world leader in applying the Vetiver System.  Be alert for more to come from that part of the world.

RESIDENTIAL PROPERTY SLOPE STABILIZATION - BRAZIL
Images - roughly in chronological order - shows some of Paulo Rogerio's work in Brazil for stabilizing steep slopes.


RECUPERACAO DE AÅLREAS DEGRADADAS
(Brazil - Portuguese) PowerPoint presentation of the rehabilitation of area devastated by major land slip at Itaipava/Petropolis, Rio de Janeiro State.  Interesting combination of engineering, matting, and Vetiver System.  Time Period January 2008 to April 2010. Work by João Henrique Eboli .


BIOINGENIERÍA DE SUELOS  (SOIL BIOENGINEERING)
(Brazil - Portuguese) An excellent PowerPoint presentation by Ing. Civil Luiz Lucena of DEFLOR covering a range of Bio-engineering techniques for slope stabilization


BIOINGENIERA DE SUELOS: HISTORIA Y CONCEPTOS
Soil Bioengineering: history and concepts - short paper in Spanish by Ing. Civil Luiz Lucena of DEFLOR


USO DO CAPIM VETIVER NA ESTABILIZAÇÃO DE TALUDES E ENCOSTAS. (USE OF VETIVER GRASS IN THE STABILIZATION OF SLOPES AND HILLSIDE)
A useful PowerPoint presentation by Aloisio Rodrigues Pereira - Bioengineering Director of Deflor Brazil - addressing the use of the Vetiver System for slope stabilization.

It is interesting that highly professional companies such as DEFLOR do an excellent job in slope stabilization using VS in conjunction with other technologies.  Countries that are subject to extreme rainfall conditions that result in landslides -  particularly in areas close to concentrated population sites should take note of what has been done in Brazil.  Hello Haiwaii, California, Venezuela, India, Thailand and others that have to mitigate against such disasters!!


World Bank and other development agencies should pay more attention too.
