2. Our term topic is ‘Changes’, we have
been investigating flax and bamboo
in more detail. As part of our research
we have looked at how bamboo's root
structure helps to prevent erosion. We
were investigating the effect of water
on sand and so the effect of erosion
on soil if there are no roots to hold the
ground in place.

18. Bamboo is ideal to help control soil erosion
Running bamboo has a net like root system that creates an
effective mechanism for watershed protection. It works to
stitch the soil together along fragile riverbanks, deforested
areas and in places prone to earthquakes and mudslides.
Studies have shown that because of this wide-spreading root
system along with the unique shape of the bamboo leaf
create a stem flow rate of 25% which means that bamboo
greatly reduces rain run-off, prevents massive soil erosion
and keeps up to twice as much water in a watershed. What
makes bamboo even far more ideal for use in soil erosion is
that it's hearty enough to flourish in areas where poor farming
practices and overgrazing have damaged the soil.
