Methane emission is usually converted into equivalent carbon dioxide (CO_2e) in order to compare it with other sectoral emissions. Estimation of methane from ‘agricultural drain surfaces’ is not accounted for in most of the derivation methods. This research paper dealt with the estimation of CO_2e emission from ‘surfaces of the agricultural drains network in Egypt’ and then estimated the projected future CO_2e emission loads trend for the period 2046–2065. CO_2e emission was estimated using general circulation models for climate change under expected temperature variation in the coming decades. Annual average total CO_2e emission loads from the BHD surface and its surrounding areas to the atmosphere were about 3790 t eq. CO_2e yr‾¹ for the period 2046–2065. The ‘additional’ total emission of CO_2e from the agriculture drainage network surface in relation to total emissions from the agricultural sector in Egypt was about 13.8%. It also accounted for about 1.4% of overall CO_2e emission in Egypt. This research paper, furthermore, developed a methane indicative emission map for the Egyptian agricultural drainage network for the period 2046–2065, through which it is possible to estimate CO_2e emission loads at any segment on any agricultural drain in Egypt during the period 2046–2065.

农业排水表面二氧化碳当量排放的分析研究——来自埃及的案例研究*

甲烷排放通常转换为等量的二氧化碳 (CO _2e )，以便与其他部门的排放进行比较。大多数推导方法都没有考虑对来自“农业排水表面”的甲烷的估计。本研究论文涉及对“埃及农业排水管网表面”的 CO _2e排放量的估算，然后估算了2046 年至 2065 年期间预计的未来 CO _2e排放负荷趋势。在未来几十年的预期温度变化下，使用气候变化的大气环流模型估算了CO _2e排放。年平均总 CO _2e从 BHD 表面及其周围区域到大气的排放负荷约为 3790 t eq。2046-2065 年期间的CO _2e yr‾¹。与埃及农业部门的总排放量相比，农业排水网络表面的“额外”CO _2e总排放量约为 13.8%。它还占埃及总 CO _2e排放量的1.4% 左右。此外，该研究论文还为埃及农业排水管网开发了 2046-2065 年期间的甲烷指示性排放图，通过该图可以估算2046-2046 年期间埃及任何农业排水管的任何部分的CO _2e排放负荷。 2065。
