Biomass, carbon stock and sequestration potential of Oxytenanthera abyssinica forests in Lower Beles River Basin, Northwestern Ethiopia

Abstract

Background Given the large bamboo resource base with considerable potential to act as an important carbon sink, Ethiopia has included bamboo in the national Reducing Emissions from Deforestation and Forest Degradation and enhancing forest carbon stocks (REDD+) and Clean Development Mechanisms (CDM) programs. However, little is known about the carbon stock and sequestration potential of bamboo forests. As a result, this research was conducted to quantify the carbon sequestration and storage capacity of Oxytenanthera abyssinica forests in the Lower Beles River Basin, northwestern Ethiopia. To this end, a total of 54 circular plots, each measuring 100 m2 with a radius of 5.64 m, were established to conduct the inventory in Assitsa and Eddida bamboo forests, the typical bamboo sites in Lower Beles River Basin. Biomass accumulation of bamboo was estimated using an allometric equation based on diameter at breast height (DBH) and age. Soil samples were taken from two different soil depths (0–15 and 15–30 cm) to determine soil organic carbon. Results Results indicate that the mean biomass of the bamboo forests in the study area accounted for about 177.1 $$\pm$$ ± 3.1 Mg ha−1. The mean biomass carbon and soil organic carbon stock of the bamboo forests were 83.2 $$\pm$$ ± 1.5 Mg C ha−1 and 70 $$\pm$$ ± 1.7 Mg C ha−1, respectively. Therefore, the mean carbon stock of the O. abyssinica bamboo forests was 152.5 $$\pm$$ ± 2.5 Mg C ha−1 to 559.8 $$\pm$$ ± 9.0 ton CO2 ha−1. Conclusion This study highlights the importance of assessing bamboo’s carbon stock and sequestration potential for enhancing its role in climate change mitigation and sustainable resource management. The O. abyssinica bamboo forests of the study area have significant carbon stock and sequestration potential. Therefore, sustainable management of these crucial vegetation resources will enhance their role in providing ecosystem services, including climate change mitigation.

Short-Term Effects of Bamboo Plantation on Soil Carbon Fractions, Carbon and Nitrogen Stocks in Eastern Himalayas, India

“…It was found that after plantation of bamboo, soil BD increased significantly with the age of bamboo, while no significant difference in SOC content was noticed. Our results are in line with findings of similar studies conducted so far worldwide, reporting that increases in BD values under bamboo soils were associated with the decrease in SOC content (Nath et al 2009;Sohel et al 2015;Abebe et al 2021).…”

Dynamics of Organic Carbon and Predictive Management Indices in Contrasting Land Use Types on Weathered Soils of Eastern Tanzania

“…Abebe et al [61] indicated that soil organic carbon was an important ecological indicator of soil quality which is determined also by the landscape. According to Abebe et al [62], soil organic carbon is influenced by different types of land use and topographic inclination. Abebe et al [62] analyzed soil organic carbon in soils with three depths of 0-50 cm, in land use types of grazing land, bushland, plantation, and cropland under topographic positions of upper, middle, and lower altitudes.…”

Furthermore, soil organic carbon was significantly higher in bushland and grazing lands and lowest in cropland [62].…”

Tissue-cultured regeneration and ecological values in major bamboo species

“…It regulates the carbon cycle and metabolism in the system. It sequesters variable carbon concentrations from the surroundings and maintains carbon concentration points through the carbon cycle (Abebe et al 2021). Bamboo conducts the carbon cycle metabolism for stabilizing carbon concentrations and the soil environment through the carbon cycle and biomass (Kang et al 2022).…”
