Why bamboo is used for Buy A Share In The Repair
Bamboo minimizes CO2 gases and generates up to 35% more oxygen then equivalent stand of trees.
1 hectar of bamboo sequesters 62 tons of CO2/year
1 hectar of young forest sequesters 15 tons of CO2/year
How it works
Bamboo removes CO2 from the atmosphere through photosynthesis by using carbon as an energy source and converting it into plant tissue which releases oxygen (O2) as a by-product
• helps retain water in the watershed
• can be harvested annually
• needs no replanting after harvesting
• is an effective erosion control plant and natural control barrier due to its widespread root system
and large canopy
• reduces runoff, prevents massive soil erosion
• sustains riverbanks
• protects surrounding environment during typhoons due to its height
regenerates and is resilient even after strong
• helps mitigate water pollution due to its high nitrogen consumption
• requires little attention during its growing/production cycle
• is well suited for agroforestry and healthy ecosystems
• requires only a modest capital investment to generate a steady income
How bamboo grows
The bamboo stems emerge from the ground as buds
with the same diameter as the final stem. All
they do is grow longer in much the same way as
a telescope, extending at a very rapid rate that
can be in excess of a meter a day in a mature
stand. When the culm is around three quarters
to two thirds tall the elongation will tend to
taper. However, they will remain the same diameter
and possibly only grow another 10% taller as they
mature over the next twelve months.
When the culm has reached full height branches will start to appear and depending on species a new shoot can be fully developed within three months.
During the shooting stage the new culm will be at least 85% water and it is imperative that sufficient water is supplied to fill these vertical liquid columns. If timber is to be harvested, there will at least a three year wait for the water content to diminish, thus allowing the tensile strength to increase.
Why grow bamboo?
As a natural and renewable resource bamboo offers an opportunity to turn away from the destruction of native forests towards managed commercial plantations that can be selectively harvested annually without the destruction of the grove or stand. Tree plantations obviously have to be chopped down and their nutrient arrest terminated at harvest. Bamboo keeps on keeping on, with edible shoots capable of extraction after less than five years.
Special characteristics of bamboo
Bamboo is one of the most important nature’s substitute for the endangered rainforest hardwoods. It is a quick-growing, versatile , non-timber forest product whose rate of biomass generation is unsurpassed by any other plants. With a 10-30 % annual increase in biomass versus 2-5 % for trees, bamboo creates greater yields of raw material for use. It is utilized extensively for a wide range of purposes. The strength of the culms, their straightness, smoothness, lightness combined with hardness and greater hollowness; the facility and regularity with which they can be split; the different sizes, various lengths and thickness of their joints make them suitable for numerous end products/purposes. The versatility of bamboo outmatches most tree species. It is known to be a natural and excellent raw material for manufacturing strong and sturdy furniture, handicrafts, and novelty items.
