Vetiver hedges, neat and trim(med)!

All of us recognize Vetiver's effectiveness in many applications. It's certainly a workhorse! However, while appreciating Vetiver's subterranean abilities, some customers want their new resource to be smart AND beautiful--all the time! Vetiver in neatly trimmed hedges presents itself as a lovely ornamental, and it can easily be maintained as such.

Posting his review of a particularly sharp hedge trimmer, a law professor in LA reported: "We had a problem. We planted 500 running feet of Vetiver grass for hillside retention. Vetiver is great for bio-engineering, in our case retaining a steep hillside, but when Vetiver is fully established, we found it too tough to cut with a Fiskars hedge shears. So we tried a power hedge trimmer, which broke the grass instead of cutting it cleanly. Then we discovered that the Japanese make hedge shears with really sharp blades. So we ordered this ARS model (ARS 28- to 41-1/2-Inch Hedge Shears HS-K900Z, Ed.). The blades are razor-sharp. The tool is light; the handles are excellent. And best of all, the shears did a great job on our Vetiver hedges."

Saipan uses Vetiver to protect its reefs!

According to our friends at the Saipan Tribune, "fifteen volunteers from three groups, along with staff from the Division of Environmental Quality and Coastal Resources Management Office, spent Saturday morning planting 90 plants within the Laolao Revegetation Project site.

The Volunteer Planting Day was part of a continuing restoration effort, started in 2005, to help reduce soil erosion, which causes sediment to wash into Laolao Bay and damage its coral reefs.

The Laolao Revegetation Project intends to plant over 1,000 saplings and 2,500 linear feet of Vetiver throughout the upland planting area. This volunteer tree planting was a way to show the community how important these projects are for Saipan.

DEQ Field Coordinator Nick Swaim demonstrated proper planting techniques and fertilizer placement. Six native plant species were used, propagated by DLNR Forestry at its nursery in Kagman.

Volunteers from the community included members from Teen Talk, NMC's Phi Theta Kappa, and NMC's Environmental Natural Resources Organization. The volunteers carried plants and tools as they hiked up to the planting site. Along the way they passed rows of Vetiver propagated at CREES Agriculture that had been planted by Tropical Gardens Landscapers. The planting was spread across two of the 16 sites in the project area. Fortunately, the volunteers were able to plant in the sites that boast the best views of the bay.

Volunteer Lorremel Hocog said, 'It was a fun exercise, and I'm doing it for a good cause. So it's worth every effort, and the view is amazing.'"

Vetiver's a beach- and coral-saving green shield!

Thursday, August 12, 2010

This just in from our friends in Bangalore, India.

Alarmed by the rapid degradation of the coastal ecosystem and the potential danger it poses to people living along the coast, the Karnataka forest department has devised a plan to prevent further damage to the beaches.

An increase in population density and economic activities in the coastal zones is pressuring the ecosystem, which can lead to loss of biodiversity, coral reef bleaching, new diseases among organisms, hypoxia, reduced water quality, and a threat to human health due to toxins in fish and algae.

Since about 60 percent of the world’s population lives within 62 miles from an ocean, any catastrophe along coastlines will cause huge loss of life. The forest department wants to prevent such disaster by fortifying the coastal regions. It is planning a "green shield" at all the beaches in the three coastal districts of the state — from Thalapady near Mangalore to Karwar, a stretch of 192 miles.

The "shield" will be a three-tier green cover with different types of coastal vegetation. Said Manjunath Shetty, asistant conservator of forests, Kundapur subdivision, “A green carpet of ipoma biloma, a creeper which grows at beaches and pins sand to the ground, will comprise the first tier. It will provide adequate cover to the beach wildlife, like small amphibian crustaceans, turtles, and snakes.

"The second tier will be made of Vetiver, an aromatic plant known for its thick network of roots and medicinal applications.

“A thick cover of trees like casuarina, calophyllum and honge (pongamia pinnata) will make up the third tier.”

A 109-mile “green shield” will soon come up in the three coastal districts of Udupi (between Karnad and Shiroor), Uttara Kannada (from Bhatkal to Karwar), and Dakshina Kannada (from Thalapady to Karnad).

Another ‘green shield’ had been set up at Kodi Kanyana sea face in Kundapur division, Shetty said. “Chief minister BS Yeddyurappa will inspect it on August 13,” he said.

“Over the centuries, due to human intervention, beaches have lost their natural vegetative cover,"said Ananth Hegde Ashisara, chairman, Karnataka Board of Biodiversity and also Western Ghats Task Force. “No human effort will be able to arrest the advance of the sea under such conditions. But nature can repair some of the damage if we initiate natural re-generation," he said.

“The green shield will protect people from disasters like tsunami, hurricane and metallic corrosion due to saline winds,” Sundar Naik, additional principal conservator of forests, added.

Sugar cane : arsenic :: love : marriage

Whew! Deriving today's title required summoning dusty recollections of analogies from the recesses of my mind. Anyway, many locals know one of Hilo's worst-kept secrets: that Hilo Bay and environs are polluted with arsenic, a by-product of the Canec industry. Canec is a building material, made only in Hawaii, that was popular and cheap, and made from sugar cane stalks treated with arsenic.

From 1932 to 1963 the Hawaiian Cane Products plant in Hilo manufactured Canec from bagasse, the fiber left after sugar cane stalks are crushed for their juices. The process included treating Canec with arsenic to deter insects and minimize mildew. Although Canec hasn't been manufactured in decades, contamination survived. At least one study reported arsenic concentrations in the sediments of Hilo Bay as high as 6370 ppm, approximately 34 times higher than anywhere else in the state.

A few years ago the plan was to cover shoreline soils with three feet of fresh soil. I'm not quite sure what that would--or did--accomplish, since the proposed fix seemed as ineffective as the discredited "solution to pollution is dilution." Nevertheless, as recently as late April, the Hawaii Tribune Herald reported that work was continuing on efforts to cover up contaminated soil on the site of the future Target and Safeway stores in Hilo, where high levels of arsenic, dioxins and petroleum compounds were found.

So, if covering up a heavy metals problem, well, only covers it, what's the alternative? Yup, you guessed it. Vetiver!

Research conducted at least since the mid 1980s confirms that Vetiver tolerates a wide range of soil acidity, alkalinity, salinity, sodicity, and elevated levels of Aluminium, Manganese, and heavy metals such as Arsenic, Cadmium, Chromium, Nickel, Lead, Zinc, Mercury, Selenium and Copper in the soil. (Truong, P., et al).

It also absorbs large quantities of heavy metals from industrial waste and, in the process, protects ground water from contamination, claim a duo of researchers at India's Kerala University.

In a paper presented at the Kerala Environment Congress 2010, concluded on Saturday, researchers D.S. Jaya and G. Dhanya report that the penetrating roots of fast-growing
Vetiver can effectively remove hazardous heavy metals from industrial effluents.

Since industrial waste poses a great threat to the environment, Vetiver will become a great boon, say the researchers, who are the faculty members of the Department of Environment Science of Kerala University. Vetiver planted around industrial firms that flush out metal-rich waste water will remove the metals from the water. "Thus the soil and ground water of the region will be protected without being degraded," Jaya said.

Large numbers of Vetiver plants could be grown in artificial wetlands around factories and industrial units and thus protect the environment, she said, adding that technologies were also available to recover the metals from the plant material.

"Another interesting fact is that the plants have shown different efficiency for absorbing different metals. Good results are shown for zinc, lead and cadmium," Jaya said.

Has Vetiver gone to the dogs? Grrr, not exactly...

From the author of the Smartdogs' Weblog 6/10/10 entry, called Animal Attraction

I like to experiment with essential oils. I love perfume. Good perfume, not cheap drugstore stuff. And essential oils not only give me a way to experiment with different scent combinations, I can also use them make my own scented soaps and cleaning products.

One day as I was playing around with mixtures of different scents while surrounded by a pack of curious dogs, I thought “I wonder what the dogs think of these?”

Anyone who’s spent a bit of time with dogs understands that they don’t make the same kinds of value judgments about smells that we do. Seriously. In case you have not already noticed the obvious, your dog adores smells like shit and week old garbage and rotting flesh and he probably thinks that smells like fabric softener and Glade air freshener are utterly revolting.

It’s easy to find scents where dogs and humans disagree. I wanted to see where the dogs and I agreed. So I collected a dozen or so vials of essential oils and four dogs (the number I had on hand) and conducted an informal experiment. I put a drop of each oil on a small piece of paper then held the sample out toward each dog in turn and let each one decide whether they wanted to explore it more intimately or not.

The results were interesting.

Being courteous beasts, the dogs politely and carefully sniffed each sample offered. They seemed to react neutrally to most of the scents, generally taking a quick, cautious sniff or two then looking at me inquisitively. All four turned up their noses at eucalyptus and avoided it. Three expressed similar distaste for tea tree and two for violet. Wintergreen made one dog sneeze; the other three refused to sniff it. I didn’t force the issue. They showed a somewhat marked interest in sandalwood, patchouli and ylang-ylang, taking a few extra sniffs and pausing thoughtfully between them.

All the dogs were mesmerized by three scents – vetiver, frankincense and oak moss. Vetiver was the clear winner. All four were entranced by it. They didn’t just take a few polite whiff of the sample – they inhaled slowly and deeply, and then paused to process the aroma between each sniff. Charlie even tried to follow the bottle into the cabinet.

While an interesting little experiment, I didn’t intend to follow it up. That is, until last week, as I browsed the beauty products while waiting for my stylist.

A row of fragrances in the Aveda aisle caught my eye. I sniffed each one cautiously. Most were a lot sweeter and more citrusy than the scents I prefer, but one hit the jackpot. Chakra 1 is a blend of vetiver, frankincense (olibanum) and patchouli, strong and woody but not overpowering. Although it wasn’t something I’d ordinarily buy, it was relatively inexpensive and, given the results of my recent experiment, I suspected that the dogs might enjoy it. So I brought a sample home.

I’m glad I did. Chakra 1 has been a big hit with the beasties. When I apply it they sniff me like a freshly decorated hydrant. And if I spritz a little on one of the dog beds, the boys will roll on it in evident ecstasy.

Because the dogs and I seem to share a preference for grassy and woodsy fragrances, I decided to test their reactions to my perfume collection. While distinctly unimpressed by most of the products, Muschio di Quercia was the paws down favorite and young Charlie displays a clear and consistent interest in Privet Bloom (lemon, bergamot and verbena on top; white hyacinth in the middle, and base notes sea grass and cucumber).

It appears that I’m not the only one checking my critters' reaction to fragrance, or even the first. Tuesday’s Wall Street Journal has the details:

Zoos have long spritzed perfumes and colognes on rocks, trees and toys in an effort to keep confined animals curious.

In 2003, Pat Thomas, general curator for the Wildlife Conservation Society’s Bronx Zoo in New York, decided to get scientific about it. Working with 24 fragrances and two cheetahs, he recorded how long it took the big cats to notice the scent and how much time they spent interacting with it.

The results left barely a whiff of a doubt. Estée Lauder’s Beautiful occupied the cheetahs an average of just two seconds. Revlon’s Charlie managed 15.5 seconds. Nina Ricci’s L’Air du Temps took it up to 10.4 minutes. But the musky Obsession for Men triumphed: 11.1 minutes. That’s longer than the cats usually take to savor a meal.

Ann Gottlieb, the “nose” who helped create Obsession, believes that a a number of factors in the fragrance might render it irresistible.

“It’s a combination of this lickable vanilla heart married to this fresh green top note—it creates tension,” she says. The cologne also has synthetic animal notes like civet, a musky substance secreted by the cat of the same name, giving it particular sex appeal, she adds. “It sparks curiosity in humans and, apparently, animals.”

According to Basenotes.com, “Obsession for Men” includes topnotes of mandarin and bergamot; heart notes of lavender, myrrh, sage, clove, nutmeg and coriander and amber, musk, sandalwood, vetiver and patchouli as base notes.

Combining Obsession’s formulation data with the results of my informal research on my dogs, I’ll say that if I was interested in animal attraction I would experiment with scents featuring simple sweet heart notes like vanilla, orange and lemon combined with strong animal and woody basenotes, like topnotes lemon, bergamot, verbena; white hyacinth as a middle note and base notes sea grass and cucumberMuschio di Quercia – a deep, woodsy scent that my dogs adore.

California dreamin'...of help from Vetiver!

California's myriad problems, from tempestuous wildfires to torrential rains, scream for relief. And Vetiver's been tried by the most austere conditions and been found true--in California, in the mid-1990s. Today Wolfram Alderson (Wolfram's World) dug up the history:

Worst case scenario provided for Vetiver grass planting at California State Polytechnic University, Pomona.

Vetiver grass was given an opportunity to demonstrate its tolerance of poor soil and environmental conditions in a "worst case scenario" at Land Lab, an 340-acre environmental study area at California State Polytechnic University, Pomona. During the summer of 1994, 44 Vetiver plants were installed along a cut face slope leading up to the Land Lab Information Center.

Vetiver was among plant materials included in a revegetation project implemented by the Casa Colina Horticulture Therapy and Training Program, a Pomona-based program that provides employment and training for people with disabilities.

The goal of the revegetation project was to restore the ability of the native California Black Walnut trees on the site to seed new generations of tree saplings. Before the project, mostly old growth trees and very few young trees had survived unfavorable conditions that had previously included overgrazing, construction activities, a canopy of invasive exotic weeds, and few surviving native or understory plants. Soil conditions were very poor and heavy erosion and landslides were prevalent.

Only "moondust and shale" soil was left after construction of a road leading to the Land Lab Information Center. Topsoil and more than ten feet of earth were removed, leaving a dry, shale-pocked substance entirely devoid of organic matter. During the summer, wind and sun pummeled lifeless dust and rock that crumbled and cascaded down the slope face onto the asphalt roadway. In winter months, rains turned the material into a gray mud that frequently slipped downhill in mudslides or simply washed down the driveway in a milky flow. As a general reference, temperatures in the Los Angeles area range from 28F to 110F, with a mean of 64.4 F. Normal Los Angeles rainfall is 14.68 inches/year. Vetiver can survive with as little as 12 inches of annual rain, but average rainfall of 27.5 inches is preferable.

When the 4‰ container-sized Vetiver was planted, portable Rainbird sprinklers provided some irrigation during the initial months following planting. However, frequent waterline breaks and other challenges starved the plants for water and attention during the first year. No irrigation has occurred at all since the sporadic watering of the first year. After a three-year revegetation period, project funding was discontinued and site maintenance was abandoned.

Remarkably, as of December 1999, 90% of the Vetiver planted at the site survived the soil, the blazing sun, the afternoon winds, and even a large population of voracious rabbits that get its water and food from the vegetation. Although the Vetiver that remains would clearly look happier if they were to get a little more water, it's amazing that Vetiver survived when other native plantings did not. When Vetiver is stressed, it "hunkers down," growing lower and exhibiting more dry bades. But, as you seen here and in other Southern California Vetiver images, Vetiver has survived here while native sages and plants considered to be more drought tolerant have not. Quite an accomplishment for this simple little clump of tropical grass!

Lyza and Karen say, "Vetiver works!"

In every movement, a time comes when "the word" becomes part of the lexicon, a time that it needs no introduction. We're not there--yet. However, glimmers of hope appear. In Hawaii, we're finally meeting people who can pronounce "Vetiver" and, in some cases, even enthusiastically relate how it can help our environment.

This week two separate bloggers embraced Vetiver--for different reasons. Thank you, Lyza Danger Gardner (lyza.com) and Karen Caplan(whatsonkarensplate.blogspot.com). Their abbreviated narratives follow.

VETIVER: MIRACULOUS GRASS SMELLS FANTASTIC, PROVIDES ENVIRONMENTAL BENEFITS

Vetiver’s present in nearly 90% of Western perfumes and its aroma is a complex weave of smoke, earth, wood, secrets, calm, nuance, and sap. The fragrance has almost no edges; in its distilled form, it’s a viscous, amber syrup that you could almost put on pancakes.

The grass is native to India and related to lemongrass, and seems calibrated to the current needs of our world. It’s grown widely in Haiti, India, and Indonesia for the perfume markets of the world, but its other talents are promoted by organizations like The Vetiver Network International.

Vetiver forms the basis of the “Vetiver System,” an interplay of the plant’s unique characteristics with its environment. It provides excellent erosion control, is easy to grow, doesn’t mind toxins like heavy metals or weird algae or phosporus blooms and, by dint of its way of propagation, is non-invasive and easily controlled.

Aromatic essential oil is distilled from its roots, which grow 12-15 feet nearly straight down and control erosion. Oil from roots 18 to 24 months old is highly prized. Like other complex and wonderful smells in the world, Vetiver oil is made up of 100 or more components. One of its most prominent is Terpinen-4-ol, a terpene shared with tea tree and nutmeg oils.

While the antiseptic effects of tea tree oil have been widely tested and documented, recent research has shown that the anti-inflammatory effect of Terpinen-4-ol may also suppress tumor necrosis factor (TNF), a primary antagonist in Crohn’s Disease.

Mudslides, Fires and Vetiver Grass

Mudslides. Fires. It seems as if Southern California experiences these plagues every year. And this year was no exception. We had terrible fires in the fall and, as our rainy season arrive, many areas in the South experienced flash flood warnings.

My most dramatic memory was after my mother and I drove back from Palm Springs to Orange County. A few days after our trip, the news reported that the very transition road we had traveled, from Highway 60 to Highway 57, was closed due to mudslides caused by heavy rains, saturated soil and fire damage.

All I could think of was, “Why aren't they planting Vetiver grass?”

What is Vetiver, you ask? According to my friends Noel Vietmeyer and Mark Dafforn of the National Research Council, this little-known tropical grass is relatively cheap and effective at preventing soil erosion. When planted in lines along the contours of slopes, Vetiver quickly forms narrow but very dense hedges. Its stiff foliage then blocks the passage of soil and debris, and slows any runoff, giving the rain a better chance of soaking into the soil instead of rushing off the slope.

Remember the horrific 2005 mudslide in La Conchita, California (near Santa Barbara), in which ten people died when an entire mountainside collapsed on top of their homes? Well, that location was also home to the only banana plantation in the western United States – Seaside Banana Gardens. (Before the 2005 disaster, a 1995 mudslide had knocked out most of this plantation.) Fortunately, the grower, Doug Richardson, only lost his bananas – he and his family were spared.

Doug still grows bananas, however, and a few years ago he wrote us about the success of his Vetiver planting (and more exotic bananas).

So, if I had a wish, it would be that someone reading this blog would pass along this information to the Wall Street Journal, the Los Angeles Times, Sunset Magazine and others, and that Vetiver would get great publicity and be planted all around Southern California so we'll NEVER have to worry about mudslides again.

So, please pass along this information…and I’ll keep you informed about how this message spreads!

Conventional v. Creative? The Father of Vetiver weighs in.

John Greenfield, the author of the groundbreaking Green Book, Vetiver: The Thin Green Line Against Erosion, and the "Father of Vetiver," just posted his views about well-intentioned but misguided efforts to help developing countries conserve soil and water.  They're well worth considering:
Misguided Aid to the Third World: the ‘Poverty’ Gap

“The road to hell is paved with good intentions.” It most certainly is.

Eighty percent of Third World poverty occurs among rainfed farmers and their extended families in the tropics. More than 40 years spent on the ground in these countries exposed me to a huge variety of well-intentioned aid agencies, donor countries and myriad alphabet agencies from the United Nations.  Their  researchers, engineers and theoretical economists have battled for decades, and battle today, to develop a workable solution to the poverty and hunger in these areas. I've met many outstanding individuals over the years, but these brilliant minds are no match for the lack of coordination and different demands and agendas of the many and varied donor agencies involved in every developing country.

Donor countries with no experience in the tropics send their "experts" into the field and make multi-million dollar investment in schemes that are doomed to failure right from the start. Government heads and UN departments listen to economists who lack field experience and allocate aid according to textbook assumptions.

A major reason for near universal failure is the myth perpetrated by successions of aid experts from developed countries that the poverty of subsistence farmers resulted from a complex historical process that does not lend itself to simple or quick solutions. Economists are injected to explain the situation, anthropologists to analyse farmers’ needs, and then engineers to construct interventions developed for temperate climes, all without seeming to reach an understanding of the basic problem. However, an interesting historical fact is that very advanced agricultural civilizations developed and flourished in some of the most arid zones of the world – in the Near East, North Africa and Central America – and then disappeared, either because they failed to conserve precious soil, water, and fuel wood, or because they employed irrigation schemes that lacked a drainage component, and ultimately salinized the most fertile alluvial areas.

The world’s population is growing at a rate close to two percent annually, and by as much as four percent in parts of Africa. Typically there are two methods of farming – irrigated and rainfed.  Irrigated land accounts for about 20% of worldwide cultivation and 40% of global crop production. However, the cost of irrigation and drainage in the 1990s averaged around $10,000/hectare but could be as high as $25,000/hectare in the drier parts of Africa. Can developing countries really be expected to establish and maintain irrigated agriculture?

No. 

It's quite obvious that the additional food production needed in future years must come from the 80% of cultivated land that is rainfed.  The only way to address the hunger and poverty situation on a sustainable basis for subsistence farmers in the tropics is through moisture conservation, specifically by controlling runoff and making the best use of the rainfall in an area. Because of increased pressure on the land, the average subsistence rainfed farmer today, loses as much as 60% of his rainfall as runoff to the drainage network, which also causes major flooding in delta areas (Bangladesh, for instance). The runoff also carries off his soil and any remaining nutrients. Annual rainfall of 1000mm is thus reduced to an effective rainfall of only 400mm, which, if it arrives at sporadic intervals, cannot sustain a good crop, and another “drought” is declared.

Over the years, many organizations have recognized the need to control runoff and resulting soil erosion and loss and have invested a lot of effort and money in rainfed regions to address the problem mechanically, employing a battery of engineering "solutions." Contour banks, diversion banks, absorption banks, waterways, retainer walls, gabions, low dams and water harvesting schemes have proven to be unsustainable in the long term. The subsistence farmer lacks the equipment and labour required to maintain such interventions, and also takes issue with the amount of productive land taken out of production by such schemes.

The upshot is that all of this aid into rainfed areas has increased erosion, compromised production which reduces food and water, and increases poverty.  The increased runoff doesn't recharge the underground aquifers that supplied fresh water to village wells or sustained perennial streams, and the resulting floods are becoming horrendous.

Lesotho, a little country in Southern Africa, is a classic example of a well-intentioned but totally inappropriate constructed soil and water conservation system that virtually destroyed it. Diversion banks and waterways have eroded into gullies and canyons, making it impossible for farmers to cross from one side of their fields to the other.  Erosion is unchecked.  Aid agencies have abandoned the country to its fate, never admitting their constructed conservation system was a tragic mistake.

Man’s efforts to intervene in nature have failed miserably. We are too impatient. We demand an immediate fix.  Companies bring in the bulldozers, get paid and get out. The results are worldwide engineering disasters. Levees (stop banks) that are expected to control rivers in a meander plain, end with the river 30 feet above the town. Diversion systems that deprive an area of its natural runoff concentrate it in drainage networks that were never meant to handle it. All of these systems requirie massive construction and maintenance costs before ultimately failing completely and disastrously.  Hurricane Katrina, for example, burst through unprotected levees in Louisiana.

What subsistent rainfed farmers need throughout the tropical world is in situ moisture conservation to produce their crops on a sustainable basis; in situ moisture conservation to produce their fuel wood; in situ moisture conservation to replenish their aquifers and once perennial streams; in situ conservation systems that farmers can install themselves and maintain without assistance.

Decades of field trials and research by dedicated scientists, extension workers and organizations across the globe have proved there is an alternative, cheaper, biological solution to resolve our erosion and pollution problems that doesn't include complicated, expensive engineering and structural designs, and contrived bureaucratic accounting and bidding procedures.  It's a grass – a quite remarkable and astonishing plant known as Vetiver (Chrysopogon zizanioides). 

High intensity rain storms in the tropics that cause runoff severe enough to cause erosion, landslides and mudslides, is a dynamic system that can't be controlled by static measures such as gabions, retainer walls, contour banks or even trees.

Use nature to control nature!

When planted as a single line, Vetiver forms a stiff, dense hedge that prevents erosion, forms natural terraces, increases soil moisture, and doesn't compete with companion crops.  Once established, Vetiver can withstand droughts, fire and floods, and will grow on highly acid or alkaline soils.  It can reclaim mine dumps, stabilize road cuttings, embankments and river banks, is economical to propagate and install, and requires only labor and hand tools.

Vetiver roots can absorb surplus nitrates and phosphates, can tolerate high levels of toxic elements such as arsenic, mercury, aluminium, and manganese,  and can protect dams and harbours from siltation.  This plant increases crop yields through moisture and nutrient conservation, grows only where planted, and is not a weed. Vetiver hedges will grow anywhere on any soil in the tropics (and subtropics), and, once established, will last for more than 100 years.

Over the past 20 years, The Vetiver Network International has had a major impact in the private sector and through worldwide NGOs (Non-Government Organisations), promoting Vetiver contour hedges to subsistence farmers in rainfed areas. Vetiver Systems are breathtakingly simple, and they work.

Vetiver.org provides a wealth of information, evidence, case studies and extensive references from field people who have successfully installed the Vetiver System, for those willing to open their minds and tackle sustainable development in a truly sustainable manner.

Thank you, California!! Come in, please!!

California Cleans Up Waste Water Using the Vetiver System

It is always exciting to see that Vetiver can be applied so successfully to resolve a problem, and its versatility in application. Bio Clean Environmental Services in Oceanside, which specializes in storm water treatment, used just a few Vetiver plants to "scrub" highly contaminated water.   Zack Kent, Storm Water Engineer, reported that the Oceanside project was an interesting opportunity because it's a very dirty site that treats wash down water from a harbor boat wash site, along with many smaller sewer spills coming from recreational vehicles (RVs) on a continuous basis. In the last two years, the system removed more than 4,000 pounds of oil-laden sediment from the pre-treatment chamber, treating 2,000 to 8,000 gallons of water daily.

Kent said that Bio-Clean chose Vetiver because of its ability to grow in saline water and address the high pollutant loads that characterize the installation.  "It was a great choice and a real success story." A power point containing images and data about this project are available for viewing on TVNI's website:    http://www.vetiver.org/USA_oceanside02.pdf


Approximately 18 Vetiver plants were installed in a concrete treatment box containing a special media.  Said Kent, "One of the ways we get the Vetiver to grow so quickly is we don’t use any soil. It’s a soil-less media made consisting of expanded aggregates and a proprietary hydroponics media. This allows for fast growth." Within 15 months the plants developed a massive root system, which collected high uptakes of N, P and a range of heavy metals.  Trimmed periodically, the Vetiver was dug up after 15 months.

The key data includes removal efficiency when comparing effluent inflow to outflow: nitrate 76%, phosphate 70%, TSS <15 microns 82% , copper 53% (undetectable), lead 100%, Zinc 79%, TPH (gasoline) 42%, TPH (diesel) 100%; TPH (motor oil) 100%, fecal coliform 84%,E. coli 79%, and Enterococci 70%

Guyana (yes, Guyana!) takes the lead. Oh, USA, is anyone there?

Guyana leaps to the fore as its agricultural minister allows that Vetiver, the simple, complex plant that we love, just might be the solution to some of his country's coastal woes.  The shocking convergence of international economic meltdown and horrific natural disasters might, just might, pave the way to increased adoption of Vetiver Systems on a scale heretofore unseen!  It's about time, don't you think!?

"The use of Vetiver grass as a form of sea defense protection may be considered by the authorities but planting of the perennial grass will have to be tested first before widespread planting can begin, says Agriculture Minister Robert Persaud, when asked by the Stabroek News last week for a comment on use of the plant as a sea defense protector.

He stated that the authorities are studying the use of the plant, and has identified the Mon Repos Beach area as an excellent site for the test planting.

According to the Agriculture Minister, a mangrove specialist will establish the areas and try different methods of planting. He noted that the perennial grass has “great potential in the area of mud bank stabilization.”

According to Persaud, Vetiver is an effective, low cost bio-engineering technology that strengthens infrastructure protection and marsh replenishment by reliably enhancing control over soil and water management. He stated that using the plant as a form of sea defense involves planting Vetiver in a geometric or natural pattern that reinforces the dynamic processes of flow and deposition.

Vetiver is a uniquely dense, erect, deeply-rooted clump grass that is non-fertile and non-invasive. The grass, whose roots mat together, can grow as high as 1.5 meters and its roots grows downwards between six and 12 feet deep, making it an excellent erosion control plant in the tropical climate. It is also utilized for perfumery, aromatherapy and medicinal purposes in some parts of the world.

For more than a year now, Joe Coxall, a commenter on Stabroek News’ website, has extolled the virtues of Vetiver. In one of his December 2008 posts, he said “This grass can grow anywhere, but it does not spread.  Instead it grows thick root bundles over 12 feet long, straight down into the earth.”

The grass itself is good cow fodder. The roots hold the soil to the land and stop the silting. Oils can be extracted from the roots, which can be twisted into string. This grass will hold together high mud embankments.

When contacted for a comment on the issue, Engineer Charles Sohan expressed reservations, recommending that authorities pursue sea and river defense infrastructure works of a more stable and permanent nature that have stood the test of time. [Perhaps Mr. Sohan should review Fiji's century-long history of Vetiver stabilization.  Ed.]

Minister Persaud, while addressing the vulnerability of Guyana’s coastland to flooding and the high cost to maintain rigid engineered structures during a workshop on mangrove restoration at the Cheddi Jagan Research Centre on March 5, opined that there are other “least cost” techniques which the Mangrove Management Implementation Comewmittee (MMIC) could examine, listing the cultivation of Vetiver as an option.

Meanwhile, the Agriculture Minister outlined several areas that the Mangrove restoration project, for which some $125 million have been allocated in this year’s budget, will adopt in accordance with the Ecological Restoration of Mangroves Protoco, including:

-understanding the normal hydrologic patterns controlling the distribution and successful establishment and growth of the targeted mangrove species,

-determining the modifications and stresses of the previous mangrove environment that are currently preventing natural secondary succession, and,

-designing the restoration program to first establish the appropriate hydrology at an appropriate restoration site, and then utilizing natural volunteer mangrove propagules for plant establishment.

The MMIC, which was formed last month, is spearheading the restoration project. The committee includes ten relevant agencies, including the National Agricultural Research Institute (NARI) which is coordinating the technical aspect of the implementation of the restoration program. NARI has since advertised for a Community Development Specialist to lead the Guyana Mangrove Restoration Project.

Vetiver saves beaches in Lombok...are Oahu and Kauai beaches next?

Our Indonesian friends, specifically the Jakarta Post through its contributors Marcella Segre and Gil Trawangan, report Vetiver's success in stabilizing  beaches and halting the erosion that killed reefs in Gili Trawangan and Gili Air. 

Imagine diving off one of the beautiful shores of the Gili islands in Lombok, West Nusa Tenggara, and finding yourself face to face with fishermen equipped with dynamite, intent on destroying the coral reef.


This was the reality as recently as 2002, before the Gili EcoTrust, a not-for-profit environmental organization, was established and signed an agreement with fishermen a few years later.  Although the bombing has now ended, thanks to the action of local conservation officials, a need remains to continue supporting the action to ensure that fishermen, now limited to fishing in two designated areas, do not return to their old habits.  Fishermen receive a monthly compensation that will be slashed if they are caught fishing outside the designated areas or using destructive cyanide and dynamite. Funded by a fee collected by dive centers, the compensation system is very successful.

“It was hard to convince the fishermen, but now our islands are more beautiful and more and more tourists come to the Gilis. It has helped all of us,” says Hari, a Gili Air resident.

The Gili EcoTrust now engages in a broad range of actions to protect the islands' environment.  Its goal is to raise the awareness among people to reduce their environmental impact on a delicate ecosystem that already has been irreparably damaged.  Information boards provide tips about such eco-friendly behavior as taking a shower and walking on the beach.  A Clean-up Day is held the first Friday of every month, and local students attend ecology classes.

The Gili EcoTrust is actively involved in the success of a Biorock project in the Gilis. Biorock structures are electrified steel structures that encourage mineral accretion to speed up the growth of the pieces of coral attached to them.  “They're not very nice to look at, but they're working,” says dive master Seb.  “You can see them sticking out of the water at low tide. They look like a bunch of steel, cement and building material. But in only ten months, the beach is already back.”  Thanks to 33 Biorock structures, the reefs off the Gili islands are now experiencing rapid regeneration.

The Biorock project is only part of a comprehensive anti-erosion scheme in the islands, where soil erosion is a real problem and beaches are rapidly disappearing.  In Gili Air, futile attempts have been made to counter erosion by growing mangroves or placing rubble on the shores.

The Gili EcoTrust has introduced Vetiver plantings.  Says Gili EcoTrust manager Delphine Robbe, “This is the best and most sustainable way to preserve our beaches.”  Hotels and businesses tend to stack sandbags or build seawalls, short-term solutions that only deflect the waves, which remove more and more sand from the beach. Since Vetiver's roots can reach as deep as five meters (15 feet), it holds the sand much more effectively and also looks more natural, she says.

Vetiver makes the News!

Oh, what fun it is to...be featured by veteran KHON TV news anchor Kirk Matthews on his Go Green2 segment. This week marks the anniversary of the December 11 '08 flood that submerged huge swathes of the Windward and Leeward coasts. That fact was not lost on Kirk, who masterfully added flood footage to our interview. Thank you, Kirk and KHON TV2, for your role in educating the Hawaii community about this remarkable plant!

Holiday wishes to all...in vineyards, in backyards, and everywhere!

Dick Grimshaw, the executive director of The Vetiver Network International (TVNI), shares his wishes for the new year and a note of appreciation for Vetiver-enhanced wine:

"Just thought I would send you all an email of good cheer for 2010. In doing so I add this image of Vetiver and grape growing in Robertson, Western Cape of South Africa. Anelia Marais, who sent it to me, tells us that it is cut four times a year for mulching and has done a terrific job in weed suppression. She says, 'To my (very uneducated) personal taste the Vetiver wines are wonderful, with a subtle flavour. I find that the normal triticale/wheat cover crop's wine has a sharp taste.' Sounds as though Roberston might be a suitable site for a Vetiver conference!!

Dubbed the 'valley of vines and roses', the Robertson district's lime-rich soils make it eminently suitable for racehorse stud farming, and of course, for good wine. The construction of a major dam at the beginning of the century brought reliable and inexpensive irrigation which led to the proliferation of Robertson's many wine estates and cooperatives.

Situated in the Breede River Valley region, the average annual rainfall is around 400 mm. Although summer temperatures can be high, cooling coastal winds - less than 100km away - channel moisture-laden air into the valley. Today, Robertson wine is renowned. While traditionally considered white wine territory and known for its Chardonnays, Robertson is also the source of distinctive fortified dessert wines and some of the Cape's most revered Shiraz.'

If Vetiver does this for grapes, imagine what it can do for other perennial cash crops!

I am really pleased with the progress that the Vetiver System has made in the past year, starting with an exceptionally good visit to Kenya, and Ethiopia where the Vetiver System is strongly moving forward. I'm pleased to report expanded use of Vetiver in India, China, Philippines, and Madagascar, among other countries, and a lot of new interest in Central and South America, USA, Italy and southern Africa. The internet offers many more references to Vetiver Systems and this unique plant.

Although I normally don't select special people for attention, this year I want to recognize the efforts of: Jack Bertel and Warren Sullivan, who are working hard to employ Vetiver in the coastal areas of the southern United States; Alberto Rodriguez for his dissemination of Vetiver information in Puerto Rico and throughout his region; Don Miller in the Pacific, who has captured the imagination of the Coral Reef folks; Fernando Costa Pinto and Paulo Rogerio of Brazil, Carolina Rivas of Chile, Yooleny Cruz of Costa Rica; Shantanoo Bhattacharya in India; Debela Dinka in Ethiopia; Elise Pinners in Kenya, and Liyu Xu in China; and Yoann Coppin in Madagascar.

Of course I thank all the old Vetiver stalwarts - Paul Truong, John Greenfield, Roley Noffke, Mark Dafforn, Criss Juliard, Narong Chomchalow, and Jim Smyle - along with many others who continue to provide feedback and support. Thank you to all of you for your support and for sharing information about Vetiver.

The use of forums and discussion boards has allowed us to share our ideas and feelings with many others, and the feedback on their usefulness has been positive.

The Vetiver System is now accepted by many people looking for appropriate technologies that can address the problems at hand. We are lucky that Vetiver has many applications, is low cost and relatively simple to understand; and meets some of the challenges of the changing and more extreme climatic conditions that we face today.

As our gift, you will, by Christmas day, be able to buy from Amazon.com the Spanish version of the Vetiver System Technical Manual that Oscar Rodriguez - coordinator of the Latin America Vetiver Network - was so kind to translate, or get a free download from Esnips.

On that note I wish you all well."

I join Dick in wishing you a peaceful holiday season, and a prosperous, healthy New Year!

Just cruisin' with....Vetiver??!!

Alarmed that people are diving off cruise ships to meet their demise? Horrified that some are tossing others overboard? Sleepless because of the worry?? It's time for Vetiver to step in!

Although alarm and horror haven't been cited as (prime) motivators, it seems that our Oil of Tranquility is due for subtle introduction into the otherwise stressful avocation of --- you guessed it, luxury lining!

"We've heard of cruise ships that smell like bunker oil and suntan lotion, but figs and almonds--and Vetiver?

These are some of the essences that will comprose a signature fragrance that MSC Cruises plans to infuse into its newest ship, the five-month-old MSC Splendida, according to a report today by industry watcher Seatrade Insider.

The news outlet says the fragrance, which will feature overtones of Vetiver, a perennial grass, was designed to enhance passengers’ sense of well-being and luxury by evoking the Mediterranean.

'Fragranced hotels are becoming a big thing and research proves that holiday memories are composed of a myriad of sensory experiences, with scent playing a key role. Seatrade Insider says the fragrance, dubbed MED by MSC, will be subtly dispersed in select areas aboard the ship via the air conditioning system and infused into cabin toiletries, table linens, bedding and towels.

MSC's fragrance announcement comes two months after luxury line Silversea said its next ship, the Silver Spirit, would have a menu of scents that can be infused through cabins upon request.

Renowned Italian perfumer Laura Tonatto has developed three options for Silversea passengers: Oltre, designed to evoke the boundless sea; Albi, made with lavender and touted as a de-stresser; and the orange-infused Fiori d'Arancio, billed as calming."

Vetiver...sweet (er, savory)!

Always attuned to the use of Vetiver as or in fragrance and food, today I noted Veronique's post concerning "The Best Chocolate in the World." If you can swallow her initial, immodest premise that French chocolate is the best (she's tossing the gauntlet, Hawaii chocolatiers!!), then consider that Christian Constant is using botanicals in his chocolate.
"Christian Constant adds a touch of essential flower oil and spice to enhance the taste. I loved the cinnamon and jasmine green tea chocolate, and the Yemen flavor. If you dare, try Vetiver, neroli, frangipani, ylang-ylang or lemongrass," she writes. Christian Constant 37 rue d’Assas Paris 6e 01 53 63 15 15 www.christianconstant.fr
I love learning the ways that chefs employ Vetiver in their culinary creations. Those of us who delight in its fragrance appreciate Vetiver's addition to a crisp gin and tonic, and ice cream (not necessarily together!). It also makes a lovely, savory martini. Bon appetit!

Vetiver...it's not just for the birds.

This feed by G. Mahadevan of The Hindu just in from Kerala, India, the birthplace of Vetiver. Our favorite plant will take a lead role in stabilizing a lake and creating a forest-like environment for birds:

Polluted and stagnant water, crumbling banks and dwindling fauna may soon be a thing of the past at the lakes inside the Thiruvananthapuram zoo. The old-world charm of the 3.5-acre lake is being recreated as part of a substantial cleaning and beautification project being implemented by the Centre for Science and Technology for Rural Development (COSTFORD).

The de-silting of the small lake at the zoo has already started. The silt from the small lake and the large, 3.5-acre one, will be deposited at the island in the middle of the latter. Clumping bamboo and Vetiver (Raamacham) will be planted along the perimeter to prevent soil erosion. In addition to purifying the air, Vetiver plants also soak up heavy metals present in the lake’s water, COSTFORD director P.B. Sajan told The Hindu.

Varieties of fish endemic to the State, and quickly reproducing, will be introduced in the water body to ensure an adequate supply of food for the large number of birds, including migratory ones, that visit the lake every day. The 1.5-acre patch of land that straddles the lake and the zoo’s boundary wall will be densely planted with trees, creepers and climbers.

The idea is to create a forest-like environment for the birds to rest and nest. Visitors will not be permitted to access this part of the lake.

An observation deck and a tower will allow visitors to see the birds at their natural best. While the deck will jut out into the lake to allow visitors to see the fish, the tower will be tall enough to allow a clear view of the lake’s island. The designs of the deck and the tower will complement the lake’s ambience.

As part of the project, rainwater that now drains from the zoo compound will be directed to a settling pond near the small lake, and then flow to the small lake. Water will enter the city’s drainage system only when the large lake overflows. Intermittent flow of rainwater through the two lakes will keep their waters fresh. A spring that feeds the small lake has temporarily been diverted to facilitate de-silting activities.

Once the lakes are cleaned and beautified a fishpond—with a fountain—encircled by benches and seats, will be created on the lawns near the Museum’s Corporation gate. This will replace the present visitor center, which is the bandstand opposite the Museum compound. March 2010 is the targeted completion deadline, Mr. Sajan adds.

Vetiver: deeply rooted in Happiness

I just knew there was a reason that Vetiver--the plant itself, not even its myriad applications--makes me feel positively giddy with delight. Apparently my pleasure is well grounded, er, founded. This just in from our Indian friends Sathyanarayana Bhat, Ph.D, and Narayana Upadhyaya, from Aditi Organic Certifications Pvt. Ltd., in Bangalore:

Vetiver Systems for Rural livelihood and Prosperity

Usheera Grass

Indians have known Usheera or Lavancha for at least 5,000 years. Although this humble Indian grass travelled abroad just 25 years ago, people from more than 100 countries now teach us how to use it for applications from organic farming to tsunami prevention.

Ramayana stories teach that twins of Lord Rama, raised by sages, were named after two Natural beings. "Lava" is a type of small bird, and "kusha" is a grass. Fragrant-rooted Khus (from Kusha - Sanskrit)is Vetiver grass! Khus means joy and happiness. Thus Vetiver's aromatic root is considered to be not only useful in Vedic rituals but also as grass that brings happiness. As a matter of fact, Vetiver conserves our nature. It's a life-saving drug, and it is a panacea for all problems of Environment and Farming.

Vetiver has leaves that grow up to six feet and roots as deep as 30 feet! People often call it a living nail. Without exaggeration, this is a fact! Imagine the height of one coconut tree under the ground. This is the depth that this clump reaches underneath the ground! The soil binding and water holding capacity of your land is facilitated by planting Vetiver in your village or farming land. Even bulldozers cannot uproot its strong, deep root system. So this plant definitely can work as a “living nail” particularly in coastal areas, not only to prevent erosion during monsoon months, but also protect against dreaded tsunami currents! Many experiments using Vetiver to prevent landslides have confirmed that it keeps soil together without using cement.

Other uses of Vetiver plant:

Well-grown plants yield lot of leaf material, which is very good mulch.
Its tender leaves are wonderful fodder for livestock. It enriches the quality and increases the amount of milk.
The leaves are used for thatching roofs. Eco-friendly sheds and houses minimize the use of cement.
The grass blades are a good source of raw material for handicrafts and hand-made paper. Thus Vetiver is a good resource for rural employment.
The root system effectively rejuvenates soil, improving soil fertility. In the course of time, Vetiver will convert fallow lands to fertile lands.
Grown in contaminated or heavy metal water, Vetiver can definitely purify it. This is helpful when industrial sewage water flows onto fertile land.
The aromatic oil distilled from Vetiver root is very expensive, so it has good market potential.
Vetiver roots are considered very good Ayurvedic medicine. They are used in Human and Livestock medicine, curing hyperacidity, piles, bleeding disorders, skin diseases, and urinary tract problems.
Senegalese farmers have found that yield is increased when Vetiver is intercropped with horticultural crops. Farmer Tony Cisse says that augmenting fruit trees with Vetiver conserves water and facilitates the increased absorption of nutrients.
Vetiver withstands hostile climates and situations, and even grows in mine dumps, where it gradually improves the soil. It even grows in waterlogged and coastal areas.
Even if fire destroys the leaves, its roots can generate the shoot system.
Diluted Vetiver oil is a very good pesticide and termite repellent. It can also prevent many plant pathogens. A leaf concoction is also mildly fungicidal.
Vetiver leaves are very good raw material for vermi-composting.

Maui--and Vetiver--are No Ka Oe!

Earlier this month, Deb and I spent a couple of days in Maui checking on Vetiver installations and enjoying the company of new and old friends. Our first stop was Lahainaluna High School, the oldest high school west of the Rockies, where history and a sense of present purpose converge. As I gazed at the juvenile planting, vivid memories of the lovely March 31st installation washed over me. Under the capable direction of working managers LHS Ag Instructor Keith Ideoka and LHS benefactor Gunars Valkirs, among others, a small group of bright, enthusiastic students nimbly clambered up the bare slope to plant Vetiver slips. As school resumes, and fall relaxes into winter, I trust that these kids--and school leaders--will recognize that the rain has finally met its match. Rushing water will no longer slice topsoil off this slope, leaving its mess on the greenhouses below!

After the school visit, we visited a beautiful Kapalua hillside estate, where a remarkable 10-month old Vetiver installation occupies a prominent place in the landscape design. Kudos to Inoke Taufa and his Friendly Island Landscaping crew, who installed a striking perimeter border and stabilized slopes using plant material from Vetiver Systems Hawaii. In another couple of months, the hedges will be dense and sturdy enough to contain the owners’ four dogs--not that they'd ever want to leave their very special Eden!

It's hot...and Vetiver's cool.

Vetiver Systems Hawaii just completed its first exhibition at Pacific Expos' 32nd Annual Home and Garden Expo at Honolulu's Blaisdell Exhibition Hall this weekend. Largely an educational opportunity, I was struck by the number of people who desperately need effective slope stabilization that won't leave them penniless. Vetiver was warmly received, and I look forward to visiting those who'd like to explore Vetiver's specific application to their sites.

We've barely reached the middle of June and the weather in Honolulu is sizzling. Oahu farmers are not immune to water shortages. Ever helpful, Dick Grimshaw sent along this link to a Thai paper addressing (and quantifying) Vetiver's ability to maintain moisture and recharge groundwater:

A Tale of Two Islands, one w/Vetiver, one w/o: Vanuatu and Molokai

This follows on the heels of 5/31/09 front page articles in Honolulu's two major newspapers, Honolulu Advertiser and Honolulu Star Bulletin, addressing the suffocation of Molokai's reef. Unfortunately, both articles gave solutions short shrift, and cursorily presented fences as a solution. Appallingly absent was mention of the use of vegetative barriers to halt the flow of sediment to the ocean--a low-cost, highly effective, permanent solution to the problem.

How do we know this?

Because we can evaluate the results of a decade-long effort in Vanuatu, whose problems mirrored those of present-day Molokai. From 1995 to 2002, Don Miller, an experienced erosion expert, led a band of dedicated local volunteers armed with sacks of Vetiver slips into Vanuatu's southern gullies, where they systematically installed rows of plants into weathered volcanic tuff and breccia on grades of approximately 35degrees where no plantings had survived. When awash in heavy rains, the bare slopes were dumping high volumes of silt onto nearby coral reefs.

Although the erosion control project was closed down shortly after the installations (the government cited "lack of funds"), the good work had been done. Vetiver slips and indigenous plantings grew into semi-permeable hedges that filtered out sediment before it reached the island's coastal waters and the reef.

Today the Fisheries Department reports dramatically improved conditions on the reefs down current from areas that have been stabilized by established Vetiver hedges for several years. Large volumes of sediment have been retained and some areas now boast a nearly-complete cover of indigenous shrubs on previously infertile, bare, eroding land. Along with the reef, the shellfish industry has recovered, and ni-Vanuatuan fishermen are happy--and grateful.

Could this success story be repeated in Hawaii? Absolutely. Success requires completion of four steps: coordination by stakeholders (landlords and land-users), an installation plan, Vetiver plants, and installers. Whaddya say, eh?! Call me: 808-536-5444. I'll answer.
