Measurement of carbon dioxide (CO2) absorption of Tam Vong bamboo in Tri Ton district, An Giang province
and
Abstract
Bamboo is a popular plant in Vietnam because it is easy to grow, requires little care, is versatile, and has the ability to retain soil and to prevent natural disasters. In particular, the Tầm Vông bamboo plant, with the scientific name Thyrsostachys siamensis, is a native plant, typical of rural and highland areas in the Mekong Delta. Tầm Vông Bamboo is considered a plant with great potential to absorb carbon dioxide (CO2), helping to reduce global warming phenomenon and the impacts of climate change.
This study applied the method of measuring fresh and dry biomass of all parts of Tầm Vông bamboo to calculate the amount of carbon accumulated from Tầm Vông bamboo specialized forests in Tri Ton district, An Giang province. Measurement and calculation results show that bamboo has the ability to absorb 9.844 tons of CO2/ha and 19.279 tons of CO2/ha for 1-year-old and 2-year-old bamboo gardens, respectively. This shows that, in addition to economic and social benefits, Tầm Vông bamboo can be expanded its area, contributing to establishing carbon credits for localities.
Tóm tắt
Tre là loài thực vật phổ biến ở Việt Nam vì đặc điểm dễ trồng, ít chăm sóc, đa dụng và có khả năng giữ đất, phòng chống thiên tai. Tre Tầm Vông là giống tre phổ biến ở vùng đồng bằng sông Cửu Long, được xem là loài cây có nhiều tiềm năng hấp thụ khí Carbon dioxide (CO2), giúp giảm thiểu hiện tượng nóng lên toàn cầu và tác động của biến đổi khí hậu. Cách trắc lượng sinh khối tươi và khô của tất cả bộ phận cây tre tầm vông được áp dụng để tính lượng carbon tích lũy từ các rừng trồng tre Tầm Vông ở huyện Tri Tôn, tỉnh An Giang. Kết quả đo đạc và tính toán cho thấy cây tre Tầm Vông có khả năng hấp thụ 9.844 tấn CO2/ha và 19.279 tấn CO2/ha lần lượt cho vườn tre 1 năm tuổi và 2 năm tuổi. Điều này cho thấy, ngoài lợi ích kinh tế và xã hội, cây tre Tầm Vông có thể mở rộng diện tích, góp phần thiết lập tín chỉ carbon cho các địa phương.
