Beach stabilization and protection

The potential for using vetiver has been demonstrated in various parts of the tropics.  The latest is from:  Luiz Lucena of Deflor Bioengineering – Brazil (+ 55 31 3284-5622 + 55 31 9322-5807  email lucena@deflor.com.br) who wrote:

"I had a recent experience using coconut fiber blankets and Vetiver to protect about 3 kilometers of a beautiful beach in Sao Paulo State, Brazil. We were amazed that the young plants (1 month) had a very fast growth during the high tides in September when they were exposed to the waves. Though, after three months when the plants were about 1 meter high, the tip of the leaves broke and dried. It did not interfere with the continuous growth of plants that reached over 2 meters in January".  The reader should also note that vetiver when grown to protect the interface of beach property will have a few additional benefits: (a) reduce polluting runoff effluent to the beach and sea (b) reduce the amount of rubbish flow from land to sea, and (c) provide for other uses such as thatch, handicraft resource material, and even fuel.  Vetiver could be safely cut at the time of year when storms are not expected.
