Sustainability of a bioenergy project depends on precise assessment of biomass resource, planning of cost-effective logistics and evaluation of possible environmental implications. In this context, this paper reviews the role and applications of geo-spatial tool such as Geographical Information System (GIS) for precise agro-residue resource assessment, biomass logistic and power plant design. Further, application of Life Cycle Assessment (LCA) in understanding the potential impact of agro-residue bioenergy generation on different ecosystem services has also been reviewed and limitations associated with LCA variability and uncertainty were discussed. Usefulness of integration of GIS into LCA (i.e. spatial LCA) to overcome the limitations of conventional LCA and to produce a holistic evaluation of the environmental benefits and concerns of bioenergy is also reviewed. Application of GIS, LCA and spatial LCA can help alleviate the challenges faced by ambitious bioenergy projects by addressing both economics and environmental goals.
生物能源项目的可持续性取决于对生物质资源的精确评估、经济有效的物流规划以及对潜在环境影响的评估。在这方面，本文回顾了地理信息系统（GIS）等地理空间工具在精确农业残留物资源评估、生物质物流和发电厂设计中的作用和应用。此外，还回顾了生命周期评估（LCA）在理解农业残留物生物能源生产对不同生态系统服务的潜在影响方面的应用，并讨论了与 LCA 变异性和不确定性相关的限制。还回顾了将 GIS 集成到 LCA 中（即空间 LCA）的实用性，以克服传统 LCA 的局限性，并对生物能源的环境效益和关注点进行全面评估。GIS、LCA 和空间 LCA 的应用可以通过解决经济和环境目标来帮助缓解雄心勃勃的生物能源项目所面临的挑战。
