1. BAMBOO GROWS FAST - LIKE REALLY FAST
According to Guinness World Records, some species of bamboo can grow up to 2.91 ft/day — or, 1.5 inches/hr! So if you sit long enough with a bamboo culm, it might just grow before your eyes!
How does bamboo grow? As a colony plant, it uses its energy to expand its roots and grow more shoots in the spring. These shoots emerge out of the ground to grow taller and wider for around 60 days. After 60 days, the canes stop growing altogether, and energy is directed back to the roots for the development of further canes. This is where bamboo differs from most other flora, which put their energy into continued growth of the original stem. Once bamboo is established (usually after 3 years), the new shoots that emerge each spring will continue to get bigger and bigger. Pretty cool, right?
2. BAMBOO HAS REGENERATION SUPERPOWERS
No, really! Cutting bamboo actually stimulates growth. How does this work? Well, rather than directing energy towards regaining its lost height, a cut bamboo stalk will simply unfurl new leaves.
These leaves, in turn, create and send energy down to the root system to encourage the growth of new shoots. The more that gets harvested, the faster it grows. That makes bamboo an incredible renewable resource that can be harvested and will regrow naturally.
3. BAMBOO CAN SEQUESTER A LOT OF CARBON
Bamboo’s incredible growth rate is impressive, and some of the reasons are less obvious — including its powerful carbon sequestration potential. When properly managed and intensively harvested, bamboo can sequester up to 1.78 tonnes of CO2 per clump per year. This translates into a CO2 drawdown curve that’s up to 10X faster than that of woody trees. That's HUGE!
4. BAMBOO FILTERS AND SLOWS THE FLOW OF WATER
Dense bamboo roots form a water barrier, and are used by coastal villages to protect their crops from getting washed out by rising water tables. And thanks to this barrier, bamboo can effectively filter organic matter (including soil nitrogen), leading some scientists to explore it as a sustainable wastewater treatment option.
5. BAMBOO IS VIRTUALLY FIRE-PROOF
Because it contains large amounts of silicate acid, bamboo is abnormally flame resistant. This is good news in fire-prone regions of the world, where other tree and grass species are regularly devastated by wildfires. Incorporating clumping bamboo into tropical reforestation efforts, then, can protect the long-term viability of projects.
6. BAMBOO IS REALLY STRONG AND FLEXIBLE
Which makes it an incredible, environmentally friendly building material — especially in earthquake-prone regions. In this regard, bamboo has been prevalent since the beginning of humanity, and has been used in place of wood, bricks, steel, and more. In fact, in some countries, bamboo stalks are used to build scaffolding. If we used bamboo for more construction purposes, we would save many trees and primary forests from deforestation.
7. BAMBOO HELPS TO HOLD THE SOIL TOGETHER
Because bamboo is a grass, it has a very shallow root system — with rhizomes only populating the top 6 inches of the soil. The rest of the roots only spread around 14 inches deeper. But because the roots are so densely clumped, they do a great job at holding the top layer of the soil together, thus preventing soil erosion.
8. BAMBOO HELPS WOMEN ECONOMICS
Seriously! The light weight of bamboo allows women to participate in the bamboo economy, giving them access to a potentially lucrative source of income. This increased economic security and standing can help secure them a place in decision-making in political, economic and public life. Some examples of products they can make with this self-sustaining resource are: bamboo briquettes, bamboo flooring, charcoal, incense sticks, and furniture. Pretty amazing, right?
