本文试图评估坦桑尼亚农作物生产和加工部门是否可以实现可再生能源自给自足，以及是否可以以环境可持续的方式实现。为了回答这些问题，对坦桑尼亚商业化生产的农作物加工残留物的理论能源潜力进行了评估。此外，还应用了一套以环境标准为重点的可持续性指标来识别使用这些残留物进行能源生产的风险和机会。特别是，评估了对土地利用系统（土壤肥力、用水和质量、生物多样性等）的积极和消极影响。结果表明，利用某些农业加工残留物进行能源生产不仅可以改善和保障能源供应，还可以提高当前土地利用实践的可持续性。
This paper attempts to assess whether renewable energy self-sufficiency can be achieved in the crop production and processing sector in Tanzania and if this could be accomplished in an environmentally sustainable manner. In order to answer these questions the theoretical energy potential of process residues from commercially produced agricultural crops in Tanzania is evaluated. Furthermore, a set of sustainability indicators with focus on environmental criteria is applied to identify risks and opportunities of using these residues for energy generation. In particular, the positive and negative effects on the land-use- system (soil fertility, water use and quality, biodiversity, etc.) are evaluated. The results show that energy generation with certain agricultural process residues could not only improve and secure the energy supply but could also improve the sustainability of current land-use practices.
