Erosion is a large factor in maintaining fertile land for crop
and animal alike and has been a large issue in many areas of the
world nepal being no exeption. Developing control systems to handle
erosion is very important to solve these issues.1Nepal
Nepal is situated in south east Asia between China, to the
north, and India, to the south. It is divided into three main
regions, the mountain region the hilly region and the terai region.
2ErosionA large issue in Nepal
Hilly and Mountainous
The Monsoon season
Deforestation
Nepal has many issues associated with agricuture and maintaining
crops due to losss of soil from erosion. The hilly and mountainous
nature of nepal as well as the vast amounts of rain received during
the monsoon season leads to soil running off and subsequently land
loss. Not only does the climate and geographical nature of nepal
lead to erosion but the large amounts of deforestation occuring.
Nepal uses the wood as an energy sourse and for timber but
exxcessiely to the point that only 30% of their natural forest
remain. 3HydromulchCellulose based growing medium
Helps seed adhere to ground
Protects from the elements and animals
Increases germination and growing rate
Plant life counteracts erosion
Hydromulch is a cellulose based growing medium for mainly
grasses. It provides a superior environment to enhanec seed growth
by helping the seed adhere to the ground better, preventing it from
running off or being eaten by animals, increasing germination by
proiding more onsistent water and fertilizer access. The mulch is
prepared by mixing the hydromulch fiber in a tank along with
fertilizer, water and grass seed, and then an be sprayed by a pump
up to a distance of 200 feet. This slurry of mulch, fetilizer and
seed can allow grass to be grown even in steep enironments where
regular planting of seed my fail as it adheres to the ground and
establishes seed quickly. 4Cable ConcreteDeveloped and Patented in
Canada
Uses interconnected steel cables anchored into the ground to
prevent erosion
Concrete cast heads can articulate and conform to steep
environments
70% open area allow for vegetation growth and water flow
Simple on-site assembly
Cable concrete was deeloped and patented by the canadian company
IECS. It employes a series articulating concrete blocks connected
by steel cables to form a mat like product that prevents erosion.
These mats are anchored into the ground and help to hold soil in
place while will moulding themseles to the enironemtn. The spaces
between the heads of concrete can be filled with vegetation and
allow water to run off without the loss of soil. 5International
Erosion Control Systems (IECS)Located in Rodney, Ontario
Factory produces Hydromulch
Employs representatives across Canada and has recently expanded
into Nigeria
Holds a patent on Cable Concrete
Trade with Nepal will bolster already booming business
The internatinal erosion ccontrol systems company is located in
Rodney Ontario. The employ 12 people at the factory that produces
the hydromulch and many more around canada as sales
representatives. The have also recently epanded into Nigeria and as
such have a background in shipping products internationally. IECS
also engineered and produce the cable concrete product and as such
hold a patent on it. The company usually distributes the mould of
cable concrete to customers wanting to install the product however
as it is far more cost effective and therefore do not produce
anything but the mould for cable concrete in the rodney factory.
Trade internationally with Nepal will help to bolster an already
thriving company. Increasing the IECS brand around the world as a
leader in erosion control systems, and allow for expansion here in
Canada as well as the potential for more effective and
revvolutionary ways of combating erosion. 6Benefits to
NepalPrevention of agricultural land loss
Prevention of fatal landslides
Government sponsored initiative with the Soil Conservation and
Watershed Management
Relatively cheap
The benefits to nepal would be immense. A lot of land in nepal
is lost each year to massive amounts of erosion. The land used for
agriultural purposes is no ecception. Using the various products of
the iecs ccan help to ccombat landloss and increase the amount of
farmable land ultimatly helping the argicultural practises of the
nepalese people. Hydromulch allows for the easy application and
inccreased rate of growth for large and small areas of ground
needing ground cover. By developing root systems in the soil the
grass anchors top soil and combats erosion. Cable concrete works
much in the same way as it proides a heavy coat above the soil to
protect it from heavy rains and floods. Anchored into the ground at
many points it creates a protective barrier and increased soil
solidarity. Not only are the agricultural lands of nepal being
devasted by erosion but many landslides during the monsoon season
have been fatal to the nepalese people. Prevention of this erosion
in towns and villages will increse the safety of people living in
areas affected by these issues. The product can be bought by
individuals but would be more effective to be emplyed by Nepals
erosion control teams the Soil Conservation and Watershed
management unit. The SCWM works to prevent land loss due to erosion
in nepal and as they have many units all of over nepal would be
able to address the issue and install systems on a widespread
basis. Hydromulch is also a much more cost effective way to grow
grass as at 18 cents a sq foot it is about half the price as sod.
Cable concrete is more costly as the mould which is sold and
licenced to installers requires cconccrete and steel both not
inexpensive products but is a more effective way at ccombating
erosion.7Thank you for your timeRhys Petersen
