Abstract

Background

In Ethiopia, highland bamboo has been cultivated in various niches: farmlands, riverbanks, woodlot boundaries, and homesteads, and agroforestry systems. However, the biomass and carbon storage of potential of bamboo forests across niches is not well characterized in Ethiopia. Therefore, this study was conducted to estimate the biomass and carbon storage potential of highland bamboo plantations in northwestern Ethiopia. To this end, a total of 60 circular plots measuring 100 m² with a radius of 5.64 m were randomly established on the homestead, woodlot, and riverbank plantation niches to conduct the inventory. The biomass storage of bamboo was calculated based on previously published allometric equations. Biomass and carbon stock variations among age-classes and niches of bamboo forests were analyzed using analysis of variance (ANOVA) and subsequent pairwise means comparisons of carbon stocks among niches were performed via post hoc Tukey test at p < 0.05.

Results

Results showed that the mean aboveground biomass (AGB) ranged from 150.18 – 191.42 Mg ha⁻¹ in the entire niches. The highest amount of AGB was stored in the homestead niche (191.42 Mg ha⁻¹) followed by the woodlot (180.11 Mg ha⁻¹) and riverbank niche (150.17 Mg ha⁻¹), respectively. The highest carbon stock (111.56 Mg C ha⁻¹) was found in the homestead niche while the smallest amount was recorded in the riverbank niche (87.52 Mg ha⁻¹). The homestead bamboo plantation has the highest biomass storage due to the application of manure and natural fertilizer, regular harvesting and management of culms, and protection from illegal harvesting and grazing.

Conclusion

This study highlights the importance of bamboo plantations in climate change mitigation. Hence, bamboo plantation should be promoted; and natural resource management and forestry departments of the government, Universities, research centers, the International Bamboo and Rattan Organization (INBAR), and other partners should work with local communities to expand bamboo plantation on their homesteads and degraded lands.

埃塞俄比亚西北部高原竹林的碳储量潜力

在埃塞俄比亚，高原竹子被种植在各种生态位:农田、河岸、林地边界、家园和农林业系统。然而，埃塞俄比亚竹林生态位间的生物量和潜在碳储量并没有得到很好的表征。因此，本研究旨在估算埃塞俄比亚西北部高原竹林的生物量和碳储量潜力。为此，在宅基地、林地和河岸人工林生态位上随机建立60个面积为100 m2、半径为5.64 m的圆形地块进行调查。根据已有的异速生长方程计算了竹材的生物量储量。采用方差分析(ANOVA)分析竹林各年龄层和生态位间生物量和碳储量的变化，随后采用事后Tukey检验进行生态位间碳储量的两两均值比较，p < 0.05。结果全生态位的平均地上生物量(AGB)为150.18 ~ 191.42 Mg ha−1。草地生态位的AGB储量最高，为191.42 Mg ha−1，其次是林地生态位(180.11 Mg ha−1)和河岸生态位(150.17 Mg ha−1)。草地生态位碳储量最高(111.56 Mg C ha−1)，河岸生态位碳储量最少(87.52 Mg ha−1)。由于施用有机肥和天然肥料，定期采伐和管理，以及防止非法采伐和放牧，竹林的生物量储量最高。结论竹林在减缓气候变化中的重要作用。因此，应促进竹林种植;政府的自然资源管理和林业部门、大学、研究中心、国际竹藤组织(INBAR)以及其他合作伙伴应与当地社区合作，在他们的家园和退化的土地上扩大竹林种植。

期刊介绍： Carbon Balance and Management is an open access, peer-reviewed online journal that encompasses all aspects of research aimed at developing a comprehensive policy relevant to the understanding of the global carbon cycle. The global carbon cycle involves important couplings between climate, atmospheric CO2 and the terrestrial and oceanic biospheres. The current transformation of the carbon cycle due to changes in climate and atmospheric composition is widely recognized as potentially dangerous for the biosphere and for the well-being of humankind, and therefore monitoring, understanding and predicting the evolution of the carbon cycle in the context of the whole biosphere (both terrestrial and marine) is a challenge to the scientific community. This demands interdisciplinary research and new approaches for studying geographical and temporal distributions of carbon pools and fluxes, control and feedback mechanisms of the carbon-climate system, points of intervention and windows of opportunity for managing the carbon-climate-human system. Carbon Balance and Management is a medium for researchers in the field to convey the results of their research across disciplinary boundaries. Through this dissemination of research, the journal aims to support the work of the Intergovernmental Panel for Climate Change (IPCC) and to provide governmental and non-governmental organizations with instantaneous access to continually emerging knowledge, including paradigm shifts and consensual views.
