The understanding of the geographical variability of biomass energy is an essential requirement for the optimal location of biomass energy conversion plants. This research presents a multicriteria GIS-based assessment of biomass energy potentials and the appropriate siting of biomass plants in Nigeria. The study applies the weighted overlay multicriteria decision analysis method. Crop and forest areas, settlement (energy supply areas), shrub/grasslands, barren land, water bodies, distance from water sources, road accessibility, topography, and aspect are the criteria that were considered for locating a biomass facility in this study. The results suggest that the theoretical, technical, and economical energy potentials of crop residues are highest in the North-East region of Nigeria and estimated at 1,163.32, 399.73, and 110.56 PJ/yr, respectively, and lowest in the South-East at 52.36, 17.99, and 4.98 PJ/yr, respectively. The theoretical, technical, and economical energy potentials of forest residues are highest in the North-West, estimated at 260.18, 156.11, and 43.18 PJ/yr, respectively, and lowest in the South-East at 1.79, 1.08, and 0.30 PJ/yr, respectively. Although most areas were identified to be suitable for siting biomass plants across Nigeria, the most suitable areas are located in the northern part of the country and include Niger, Zamfara, the Federal Capital Territory, Nassarawa, Kano, Kebbi, Kaduna, and Borno State. The study supports the Nigerian bio-energy policy that proposes to effectively utilize Nigeria’s non-fuelwood as a substitute for the felling of trees. This is very important to strengthen its commitment at the COP26 International Climate Conference, which is to conserve and restore its forest. Furthermore, this study will serve as a good reference for policymakers to make well-informed decisions on tackling the energy insecurity in Nigeria.

基于多标准 GIS 的尼日利亚生物质能源潜力评估

了解生物质能源的地理变异性是生物质能源转化工厂最佳选址的基本要求。这项研究提出了基于地理信息系统的多标准生物质能源潜力评估以及尼日利亚生物质工厂的适当选址。本研究采用加权叠加多准则决策分析方法。农作物和森林面积、定居点（能源供应区）、灌木/草地、贫瘠土地、水体、距水源的距离、道路可达性、地形和坡向是本研究中考虑的生物质设施选址标准。结果表明，尼日利亚东北部地区作物秸秆的理论、技术和经济能源潜力最高，估计分别为 1,163.32、399.73 和 110.56 PJ/年，东南部地区最低，为 52.36 PJ/年。 、 17.99 和 4.98 PJ/年，分别。森林剩余物的理论、技术和经济能源潜力在西北地区最高，估计分别为 260.18、156.11 和 43.18 PJ/年，东南部最低，为 1.79、1.08 和 0.30 PJ/年分别为年。尽管尼日利亚大部分地区都适合建设生物质发电厂，但最合适的地区位于该国北部，包括尼日尔、扎姆法拉、联邦首都特区、纳萨拉瓦、卡诺、凯比、卡杜纳和博尔诺州。该研究支持尼日利亚的生物能源政策，该政策提出有效利用尼日利亚的非薪材作为砍伐树木的替代品。这对于加强其在 COP26 国际气候会议上保护和恢复森林的承诺非常重要。此外，这项研究将为政策制定者在解决尼日利亚能源不安全问题上做出明智的决策提供良好的参考。
