Rebuilding Haiti must start from the ground up, with agricultural education
Vetiver not only holds moisture it protects plants next to it from many insects, alley farming banana trees next to vetiver makes them grow healthier and faster.
Besides forage for animals or the soil it can be used in composting. Vetiver compost has an amazing bacteria and soil building mulch releasing natural NPK into the soil. Vetiver cuttings can be used green in composting toilets for heating up the pile for faster decompostion, making great fertilizer for gardening. If it could be baled it could contain humanure compost piles. It also can be used loose to line wooden compost piles to contain and cover humanure for the thermophilic heating and keeping flies away.
Vetiver has the highest photosynthetic activity of any plant according to Dr. Massimo Maffei of the University of Turin Italy. Many other plants produce more tons per acre but contain 50% more moisture. Vetiver hay is easily dried in a few hours and can produce 70 to 80 tons per hectare of cellulsic biomass with adequate water and nutrients. Best of all is its easy grow and harvest 2 to 3 times per year.
One pound of dry vetiver grass delivers 7,000 BTU
One pound of high grade coal delivers 14,000 BTU
One pound of peroleum delivers 18,000 BTU
But vetiver grass is 1/3rd the cost per ton of BTU value than petroleum or propane gas!
Buying propane that comes from outside Haiti also drains the economy, using vetiver grass as fuel will also fuel the economy!
Biochar; compacting vetiver into hockey puck sized briquets for cooking fuel
Handicraft material; many Haitians already wear vetiver hats.
Thatch; can be used for homes, chicken coups and sheds
Essential oil from the roots is possible if grown near volcanic granite (mostly found near Les Cayes area) which gives it the distinct fragrances needed for extracting. Ground surrounding vetiver clumps must be protectedfrom the uprooting to save remaining soil for replanting.
We know vetiver's capable of stopping erosion and cholera from spreading by keeping fecal matter behind hedgerows. Terraces created behind the hedgerows compost dirt with microorganisms that kill cholera in matter of hours keeping it from getting into more water supplies.
