About World Bamboo Day
World Bamboo Day is observed on September 18 under the stewardship of the World Bamboo Organization (WBO).
WBO says it created the initiative in 2009 to raise awareness of bamboo and its environmental, economic, social and cultural uses.
Why World Bamboo Day matters
The observance highlights bamboo as a plant, material and livelihood resource and encourages discussion of responsible cultivation, design, research and community use.
Claims about sustainability depend on species, land management, processing, transport, labor and supply-chain conditions; the observance does not make every bamboo use inherently sustainable.
