When it comes to biomass production from agricultural residues, Africa is playing a vital role due to the reliance of many countries within the continent on agriculture as the main Gross Domestic Product (GDP) contributor. Africa has the opportunity to leverage residues from its high agricultural production to bridge the electricity access deficit. Therefore, the objective of this study is to analyze the trend in crop production, and the contribution of crop residues for clean power generation in Africa from 1990 to 2021, using data from existing literature, as well as Food and Agriculture Organization Statistics (FAOSTAT)| and International Energy Agency (IEA) online database. The analysis showed that yam, plantain, cassava, sorghum, and millet production are concentrated in Africa, accounting for 97 %, 64 %, 63 %, 49 %, and 48 % of global production, respectively. Analyzing the trend in bioelectricity generation indicates that, biopower production in Africa only increased significantly between 1990 and 2006 followed by a steep decrease from 2006 to 2007 due to policy and technical failure. It was found that the highest contribution of bioelectricity in electric energy consumption is related to the year 2006 (0.41 %). This peak contribution dropped to 0.28 % in 2020. With the increasing trend in crop production in Africa and the decrease in bioelectricity generation and consumption, it is concluded that crop residue production alone cannot be a good measure of biomass potential for bioelectricity generation as reported in many studies without looking at other driving factors. Therefore, the study has proposed factors for increasing bioelectricity generation in Africa.

农作物生产和农业生物质发电对非洲清洁能源转型的贡献：1990年至2021年趋势分析


在利用农业废弃物进行生物质生产方面，非洲发挥着至关重要的作用，因为非洲大陆许多国家都依赖农业作为国内生产总值 (GDP) 的主要贡献者。非洲有机会利用其高农业生产的剩余物来弥补电力供应不足。因此，本研究的目的是利用现有文献以及粮食及农业组织统计数据（FAOSTAT）的数据，分析1990年至2021年非洲农作物生产的趋势以及农作物秸秆对清洁发电的贡献|和国际能源署（IEA）在线数据库。分析显示，山药、大蕉、木薯、高粱和小米的产量集中在非洲，分别占全球产量的97%、64%、63%、49%和48%。分析生物发电的趋势表明，非洲生物发电产量仅在1990年至2006年期间大幅增长，随后由于政策和技术失败而在2006年至2007年急剧下降。结果发现，生物电在电能消耗中的贡献最高与2006年有关（0.41%）。这一峰值贡献在 2020 年下降至 0.28%。随着非洲作物产量的增长趋势以及生物发电和消耗的减少，得出的结论是，仅靠作物残余物产量并不能很好地衡量生物发电的生物质潜力，如许多研究没有考虑其他驱动因素。因此，该研究提出了增加非洲生物发电的因素。
