UNEMPLOYED COAL MINERS BEING HIRED
TO ECOLOGICALLY RESTORE MINED LAND!
Since 2010, over 8.1 million square miles have been added to the world’s network of national parks and conservation areas, an area greater than the land mass of Russia.
The next global biodiversity framework is due to agree at the UN Biodiversity Conference in Kunming, China, in October 2021 and is anticipated to include the ambition to scale up coverage and effectiveness of protected and conserved areas.
How Great, IF those Red Dots on the Inactive-mine map were on the Conserved Land map.
Vetiver can do it!
What is Vetiver?
A clumping grass, 2 meters tall and 0.5 meters wide at the ground level, most often used specifically in an unbroken hedgerow system for erosion control.
The extremely deep vertical roots and stiff stems can increase shear strength of soil, slow flowing water and force silt to accumulate out behind it, backing up soil/organic matter and growing from higher nodes over time.
Some hedges are at least 100 years old and have created 2m high terraces behind them.
Fast-growing, very drought-tolerant, frost-tolerant, salt-tolerant, inundation-tolerant, pH range-tolerant, heavy metal-tolerant, will regenerate from the crown after a fire, and can be cut 2-4 times a year for bulk sterile mulch.
The roots are aromatic and used for essential oil.
Leaves are used for fodder, handicrafts, and roof thatching.
Will allow native plants to establish and when the Vetiver is shaded out it will weaken and die, therefore not crowding out native species in the long term. Vetiver planted within 50cm-1m of crops will not compete due to the downward nature of the roots.
Perfect for landslips, cuts, gullies, overflows, dam walls, or silt capture.
It’s possible to repel cane toads from water sources when planted effectively.
Used to phyto-remediate and bio-accumulate nitrogen, phosphorous, metals, antibiotics from grey and black water, either in reedbed or bunded systems or floated on pontoons and grown hydroponically.
Erosion QLD is a one-person organic TVNI-certified operation, in Australia, that supplies Vetiver propagation ‘slips’ plus the advice you need to start your own Vetiver nursery or small project so you can apply the ‘Vetiver System’ on your property and other works.
The United States could use the Vetiver System much more,
and here is an illustrative Story:
From: Vetiver Grass: A Thin Green Line Against Erosion (1993)
In 1989 Fort Polk, an army base in Louisiana, which is located at the headwaters of three scenic streams, were filling with silt as tanks on training maneuvers ripped up the land.
The desecration of these waters eventually brought in the army engineers who laid check dams across the streams. That, however, did not solve the problem: the waters sluiced right over the top and muddied the streams as much as before. Then Mike Materne, the local U.S. Soil Conservation Service agent, was brought in. By coincidence, he had just heard about vetiver. With little hope that it would do much good, he obtained some plants.
His pessimism was all the more justified because the sites to be protected seemed hostile to any vegetation: the soil was down to almost bedrock (“C horizon”), the little that remained was very acidic (pH 4.0–4.2), and it contained virtually no fertility. In the spring of 1990 , Mr. Materne planted the vetiver side by side on the bare slopes, immediately above each check dam. [At a cost that was about 60% of what additional terrace excavation would have been.]
Some of the vetivers had to be planted into waterlogged soil. Others had to be planted into pure sand, described by Materne as “drier than popcorn.” Most of the plants in each of the four sites, from the wettest to the driest, survived. Moreover, a few of them withstood yet another adversity when a freak fire swept through one of the plantings. It scorched and even killed surrounding pine trees, but the vetivers all survived.
In fact they did more than survive—they thrived. In 8 weeks some were almost 2 m tall. In 10 weeks they had grown together into hedges. And on one site, more than 20 cm of sediment had built up behind the thin green line of grass. The hedges were so effectively filtering the runoff that the old flow of mud and silt down the streams was largely cut off. The check dams were receiving mostly clear water.
When first hearing of Materne’s proposal to plant vetiver, the local county agent disapproved. But he was overjoyed—when native grasses, wildflowers, shrubs, trees, and vines came crowding in behind the hedges and grew to revegetate the site. He even declared that nothing like it had been seen in the area before.
By that time it was clear that vetiver was acting as much more than an erosion trap; it was a “nurse plant” that was protecting other native species and thereby giving these devastated watersheds a chance to heal themselves.
Any Forester or Conservationist, grounds maintenance person, public parks service, construction and landscaping supervisor, Landscape architect, Gardener, etc., who has ever been confronted with a Land Erosion problem or an Abandoned Dried-out Desertified piece of land, should know about Vetiver. Vetiver has turned into a business for people worldwide.
Come on everyone!
The verdict has been in for years, Vetiver really is a Miracle Plant when it comes to Repairing destroyed Land!
Let’s “Heal the Scars”!

2019 – Our study is the first report of using biomass harvested from vetiver grass grown in Copper (Cu)
contaminated soil for bioethanol production. Planting vetiver grass on stamp sand had a positive impact on reducing soil erosion. The harvested biomass showed significant and favorable changes in lignocellulosic composition and downstream bioethanol yield. The hydrolysates and residual biomass
waste had low levels of Cu, which would eliminate any additional cost of disposal. Further scaled-up studies and life cycle analysis are required to assess the feasibility of using metal contaminated biomass for second-generation biofuel production.

Although Vetiver has relatively high tolerance to salinity as compared with some common crops and pasture species, its effectiveness in phytoremediation is sometimes affected under highly saline conditions. However, this limitation can sometimes be overcome by manipulating the planting conditions during establishment phase, as shown in this presentation. EFFECT OF SOIL SALINITY ON VETIVER GROWTH

Aside from being hostile to plant growth, the slimes dams present severe dust, acsthetic, and acid mine drainage environmental problems. These dams are also located in harsh climatic conditions including low rainfall and temperatures which range from -5 o C in winter to plus 30 o C in the summer. Trial survival planting has shown that Vetiver represents an ideal plant material for stabilisation of gold mine and slimes dams. Vetiver has survived successfully for nearly 4 years on slimes dams. Its use as a stabilisation medium is now accepted by the Gold Mining Industry, and applications are being widely considered in the new South Africa. Vetiver in a Southern African context

Water quality was monitored by chemical analysis of samples every 28 days and at the end of the experiment (364 days). There was higher net removal of Fe (81%) and Pb (81%) with lower removal of Ni (38%), Zn (35%), SO42− (28%), Mn (27%), Cr (21%), Al (11%) and Cu (8.0%). Metals were mainly localized on the root surface as Fe plaques, whereas Mn and Zn showed greater translocation from root to shoot. Furthermore, toxicity characteristic leaching procedure showed that vetiver biomass was not hazardous waste as a result of metal accumulation.

The Verdict is in!
Vetiver is the best thing
to heal the land!
If I have not pointed to a problem that you are concerned about in my list below, let me know! So that I can add it to Positive Healing Results from Planting Vetiver
|Mine/Land Damage||Positive Results from Planting Vetiver:|
|Air – wind|| 2000 – In a trial comparing the effectiveness of |
vetiver hedges and wind barriers in controlling dust
storms and promoting the establishment of ground
cover on a 300ha gold tailings dam, vetiver has proved to be far superior and much cheaper than the wind barrier and equally effective in promoting native grass establishment. Vetiver growth after the first year was 1.5m tall and has survived several windstorms, which flattened several sections of the wind barrier in the last 12 months. THE GLOBAL IMPACT OF VETIVER GRASS TECHNOLOGY ON THE ENVIRONMENT
|Agriculture||Entomologist Johnnie van den Berg |
(Potchefstroom University, South Africa) found that (corn borer) larvae prefer to lay eggs on vetiver leaves planted around the crop instead of on the maize or rice crop itself. Vetiver leaves are hairy, the larvae that hatch on them cannot move around easily, resulting in about 90% of the eggs are dead. Vetiver also harbors many helpful insects that are predators of pests that attack crops.

samples taken from areas planted with vetiver grass are greater than those without vetiver grass. MICROBIAL BIODIVERSITY IN THE RHIZOSPHERE OF VETIVER GRASS GROWN IN QUANG NAM PROVINCE AND DA NANG CITY
2002 or later – As a pioneer species it enables
native species to establish on degraded sites where under normal circumstances it is impossible for the latter to develop. Vetiver grass provides habitat, shelter and forage to fauna. ECOLOGICAL IMPACT OF VETIVER IN FOREIGN ENVIRONMENTS
|BioFuel / BioChar||2010 – Haiti Reconstruction is promoting TLUD stoves – “Top Lit Up Draft” gasifiers stoves as the best stove design for Haiti. These stoves are relatively cheap and will burn any sort of fuel including grass. Vetiver grass produces very high heat output compared to other species; they burn cleanly and efficiently, no dirty charcoal, smokeless, and produces BIOCHAR that can be returned to the soil. …|
From Gueric Boucard:
1) According to Dr. Massimo Maffei of the University of Turin, Italy, Vetiver is the one plant on the planet with the highest photosynthetic activity. What this means, is that, given x amount of sunshine and sufficient water and nutrients, vetiver produces the most dry biomass per unit of time.
2) …Vetiver Hay is easily sun dried in a few hours, and produces up to 70 or 80 dry-tons per hectare of cellulosic biomass with adequate water and nutrients. Unlike other biomass, vetiver grows above ground and is relatively easy to harvest, by hand or with the right, specially designed Mower. …3) … An established VETIVER plantation is a veritable BIOMASS FUEL FACTORY that only needs to be mowed as needed, any time of the year.
…If bilateral and multilateral development agencies would just stand back and THINK for a moment, they would soon realize that the Vetiver System will not only mitigate against extreme weather conditions, but will conserve soil, moisture and increase crop yields: and the residues can provide fuel for cooking and heat. What more can you ask from one of the cheapest and friendliest green technologies on Planet Earth. In other words the Vetiver System is key for tackling CLIMATE CHANGE issues.

|Not-Invasive|| 2021 – Hi Lesley. The issue of sterility is at the |
heart of why the vetiver species we promote does what it does. There are 11-12 species of vetiver that we know about. Only one, Chrysopogon zizanioides is “sterile”. All the others produce fertile seed and reproduce that way. Chrysopogon zizanioides flowers, but does not produce viable seeds and cannot reproduce by making seeds. It does not have underground lateral stolons or rhizomes (think bamboo) that allow plants to move and spread laterally. This means that the only way to propagate Chrysopogon zizanioides is by splitting up clumps of vetiver into slips and planting out the slips. The implication here is that Chrysopogon zizanioides does not spread out and remains where people plant them. It does make a clump of grass that is well defined (does not get any wider at the ground level than about 12″ in [~30 cm] in diameter) and when planted in a row close together makes a hedge that stops erosion cold. Add to this the fact that this vetiver is a perennial that continues to grow in that clump for decades, you get hedges on the land that can remain for a lifetime. One of our earliest books was called, “The Thin Green Line Against Erosion”, Linkedin and email: Mr. Dale Rachmeler, [email protected]
Almost all Chrysopogon zizanioides vetiver grown worldwide is vegetatively propagated;
bioengineering has shown as essentially the same nonfertile cultigen by DNA profiling. This is a very important distinction, one that TVNI stresses as they do not promote the use of the other 11 fertile vetiver species.

|Slope Protection||2013 – Due to its excellent adaptability and |
resilience (against drought, wet, cold, heat, acid
and alkali), it is widely used in slope greening
projects of existing railway lines. It has strong
resistance, growing rapidly with developed root
system (up to 3 m in depth). It can grow in very
poor or compacted soil, in soil with strong acidity
and alkalinity, even in soil with aluminum toxicity.
According to studies, vetiver root tensile strength
reached up to 75Mpa, the equivalent of 1/6 of
ultimate tensile strength of general steel. Thereby
its penetration ability is intense enough to
penetrate rock cracks and its root system becomes
network deep into the ground, forming large-area
contact with soil, fixing the slope effectively and

|Stablize Land||1997 – Stabilization of special structures wherever |
concrete structures interface with soil a point of
“weakness” is created, particularly if subjected to
high velocity water flows. We saw many sites on
the Bekobai road (see attachment 3 for details) as
well as national highways where river crossings,
bridges and culverts had washed out because of
the interface “weakness”. In every case the
damage could have been averted if a very small
amount of money had been spent on planting
vetiver at and around the interface. In most cases
this expenditure would have been less than $500
per structure, often no more than $10!!
…When planted as a contour hedge it acts as a
continuous filtering system, that slows down
rainfall runoff, reduces rilling and gullying, and
collects soil sediments at the hedge face. Soil
and nutrient loss is reduced, soil moisture and
ground water improves significantly, and natural
terraces and ground levelling develops behind
the hedge. An important feature is that vetiver
grass takes up minimal space and is virtually
non competitive with adjacent crops. The Potential

|Temperature||2021 – Hello, Lesley, Vetiver is a C4 plant and |
thrives under hot temperatures. As you move the
plant into cooler temperatures its growth rate
declines, it may in some cases survive but not
thrive. However if the ground freezes permanently
for a week or more the plant is generally killed off.
Vetiver does not grow well in England or Ireland
where there may not be any permafrost in winter
but the summers are cool. Of course this may
change with climate change. One of the Pioneers!

VETIVER – THE PLANT
|Treat Contaminants||2019 – Conclusion: …The high efficiency of Vetiver |
grass in treating both organic and inorganic
chemicals suggests that the grass could be used
to develop a cost effective and environment

tolerates a wide range of pH (3.5-11.5), salinity
and heavy metals such arsenic, Cadmium, Copper,
Chromium, Lead, Mercury, Nickel, Selenium and Zinc. It could also absorb large amount of Nitrogen,
Phosphorous and Potassium. Its extensive and deep root system could reduce or eliminate deep nitrate leaching to groundwater. Effectiveness of Vetiver Grass versus other Plants for Phytoremediation of Contaminated Water
|Vegetation Destroyed|| 1999 or later- Kimberlite by nature is dark in color, |
easily weathered, high in smectite clays and may

Vetiver have been conducted on both tailings
dumps and slimes dumps at several different sites.
In all instances where plants were successfully
established, vetiver has been found to grow
vigorously on kimberlite spoils and metboth the

|Water Velocity|| 2000 – When planted in rows, vetiver plant will |
form a hedge, a living porous barrier which slows and spreads runoff water and traps sediment. As the water flow is slowed down, its erosive power is reduced and at the same time allows more time for water to infiltrate to the soil, and any eroded material is trapped by the hedges.

Thank you Lesley for connecting with me. I am very interested in both topics that you raise:
*Using vetiver to restore, heal barren lands, deserts, poverty; and
*Vietnamese Farmers planting vetiver grass during the pandemic year.
We are working on both of these issues.
As you know, Vietnam is one of the few countries most affected by Climate Change. Rising sea levels to extreme weather, prolonged droughts, and rising average temperatures have all affected agriculture and farmers. Currently, Vietnam has about 40% of the population ( 36 million people) directly dependent on agriculture, while the forest area in Vietnam is seriously declining in forest quality, tree density in the forest, especially the area of primary forest has been greatly reduced. So far, only 0.25% of the country’s area is primary forest.
On the other hand, Vietnam is a developing country, investment in infrastructure construction, especially irrigation systems and large reservoirs, is very limited.
Therefore, in the current climate change context, Vietnamese farmers desperately need water. They need to change their mindset to accommodate less and less water from irrigation systems pumping groundwater, or water from reservoirs, but in turn, more rainfall may be expected (Rainfall Average in Vietnam is 1,800mm / year). They have to change their mindset to store more rainwater into the ground, to convert rainwater into more groundwater.
The Vetiver System cultivation method is very helpful for drought and maximum conservation of rainwater.
We planted vetiver right next to tree trunks and seedlings. We mulch our trees and seedlings with Vetiver. This helps farmers to be active in the biomass source to cover the soil at the base of the tree, reduce the cost of buying straw or having to store it. When covering the soil with Vetiver leaves, the soil temperature stays cooler during the day and warmer at night, the difference between day and night temperature is more level. This results in cooler soil, less evaporation, better roots and soil microorganisms, and gradually higher densities.
The roots of the grass grow long and deep and, during the rainy season, they absorb more water, convert it into more groundwater, reduce surface runoff, prevent erosion, leaching, and landslides.
In the dry season, the Vetiver grass-root system has a structure similar to a wick, which will absorb water from deep at the bottom and bring it to the surface, making the surface soil moister, crops with a shallow root system can withstand drought and ensure livelihoods for farmers, because their fruit trees and vegetables are not depleted or died by drought.
All our vetiver farmers are doing this.
Since 2017, when I learned about vetiver, I decided to promote it to Vietnamese farmers regarding its many uses. In 3 years, 2018- 2019-2020, vetiver has gained the attention of more Vietnamese farmers and become a grass species sought by many farmers.
>>We are instructing farmers in the driest regions in Vietnam – Ninh Thuan province to use vetiver as a pioneer plant in agriculture.
>>We also instruct many reforestation groups in Dak Lak, Gia Lai, Kontum, Quang Tri, Dien Bien, Son La … to use vetiver and sapling symbioticly (together) to restore forests.
>>Farmers in the South, the Mekong Delta, plant grass to keep the soil bank from landslides, and change the clay structure of the soil to become looser, retaining more water through the increase in the organic ratio in the soil.
>>The grass is used as fodder in the dry season, where the Vetiver decreases salt level during drought. In doing so, farmers will also repair to saline intrusion caused by sea-level rise.
I am also involved with some NGOs in Vietnam to raise awareness about climate change, soil erosion, landslides, drought, and livelihoods. Most of the slopes of Vietnam are experiencing very serious land erosion. Vetiver will solve this problem.
Vietnamese farmers already know how to use the vetiver system as a biological water pump to ensure water for crops.
We call it symbiotic farming.

Vetiver grass is ideally designed to address infrastructure development and protection, due to its soil binding and strengthening properties combined with its capacity to reduce water flow velocity, prevent erosion and accumulate silt, spread and divert water runoff, increase water infiltration, and penetrate dense, difficult, hardpan and rocky layers of soil. The application of Vetiver System solutions ensure the longevity of infrastructure investment, restoration and protection. Veticon Cunsulting
NOTES ON THE VISIT TO SPAIN IN JULY 2016 by Mr. Paul Truong
Anna and Dave became involved with Vetiver soon after they purchased their home at Sayalonga, Spain. They had a severe erosion problem on the newly created terraces. They wanted to find an inexpensive and ecologically friendly solution to their problem. They found Vetiver through the website of TVNI at www.vetiver.org. They bought their first plants from Sardinia, Italy.
After planting Vetiver the erosion stopped within the first few months. After about 3 years they started dividing plants and planting more and more to solve erosion issues on other areas of the property. Then neighbors wanted to buy Vetiver as they had the same problems with erosion. So VetiverSpain was born and it is now the
biggest vetiver plant supplier in Europe, the company supplies high quality bare root slips and potted plants
Vetiver helps other plants grow.
In fact, because it is sterile it will help native plants take hold in a damage area and then if the shade increases enough, it may eventually die out.
Vetiver repels many insects including termites.
