Global warming as a result of increased greenhouse gases (GHGs) concentration in the atmosphere is threating the existence of life on earth. Reducing the concentration of such gases with sequestering mechanism on the surface of the land helps to treat the problem. One of such methods is trapping carbon in the form of soil organic carbon (SOC) together with sediments, by implementing sediment trapping practices. Direct field measurements, calculations and laboratory analysis were used. The result shows that sediment storage dams (SSDs) sequestered/trapped ~ 60.97*103 t of sediment with the SOC content ranged from 14 to 87 g kg− 1 and check dams (CDs) trapped 7.8*103 t of sediment with the SOC content ranged from 20 to 290 g kg− 1. In general, the studied SSDs and CDs sequestered ~ 44.68*105 kg of SOC together with ~ 68.8*106 kg of sediment. In this study, SSDs and CDs were found to be important SOC sequestering practices together with sediments. Thus, it is concluded that soil and water conservation structures can be used as carbon sequestering methods to reduce the concentration of GHGs in the atmosphere in addition to reducing soil erosion.

埃塞俄比亚西北部，检查水库和堤坝，防止沉积物，碳固存，以缓解气候变化

大气中温室气体（GHGs）浓度增加导致全球变暖正在威胁地球上的生命。利用螯合机制降低土地表面此类气体的浓度有助于解决该问题。其中一种方法是通过实施沉积物捕集实践，以土壤有机碳（SOC）的形式捕集碳以及沉积物。使用直接现场测量，计算和实验室分析。结果表明，SOC含量在14〜87 g kg−1范围内的沉积物蓄水坝（SSDs）被隔离/截留了〜60.97 * 103 t，而SOC含量为7.8 * 103 t的止水坝（CDs）被截留/截留了范围从20到290 g kg-1。通常，研究的SSD和CD隔离了〜44.68 * 105 kg SOC和〜68.8 * 106 kg沉积物。在这项研究中，发现SSD和CD与沉积物一起是重要的SOC隔离措施。因此，可以得出结论，水土保持结构可以用作固碳方法，以减少土壤侵蚀，同时减少大气中温室气体的浓度。
