This study presents a set of essential parameters specific to geography, climate, soil conditions, and irrigation, which can be used to classify commercially feasible Jatropha farming land, globally. The results are demonstrated considering Nepal as a representative case and including system-level economic feasibility and environmental sustainability analyses for each of the Federal States of Nepal. Probabilistic results describe a distribution of the minimum selling price and greenhouse gas (GHG) emissions of Jatropha-based biodiesel, respectively, with an average of $1.35/L and 46.51 gCO2e/MJ-biodiesel, and the 95% likelihood to be less than $4.57/L and 127.67 gCO2e/MJ-biodiesel. Considering direct, and then both direct and indirect land use changes increase the GHG emissions relative to the baseline by 3.5 and 8 times, respectively. Jatropha oil yield, biodiesel yield and recovery rates, and Jatropha seed production rates were found to be the most influential factors on the selling price of biodiesel and associated GHG emissions. The results imply that at the Jatropha oil yield of 50 wt%, a Jatropha seed yield of at least 3.9 t/ha and 5 t/ha are required to achieve a market-competitive biodiesel selling price of $1/L, and GHG emissions including direct land use change effects below the petroleum baseline of 87.2 gCO2e/MJ. Avoiding the disturbance of forest lands in favor of Jatropha afforestation is one of the identified strategies to minimize the impacts from land use changes. These methods demonstrate a pathway towards addressing current challenges and developing an environmentally and commercially viable Jatropha-based biodiesel industry in many countries including Nepal.

这项研究提出了一组特定于地理，气候，土壤条件和灌溉的基本参数，这些参数可用于对全球商业上可行的麻疯树耕地进行分类。以尼泊尔为代表案例证明了结果，并包括了尼泊尔每个联邦州的系统级经济可行性和环境可持续性分析。概率结果描述了麻风树型生物柴油的最低销售价格和温室气体（GHG）排放的分布，平均为$ 1.35 / L和46.51 gCO2e / MJ-生物柴油，而95％的可能性小于$ 4.57 / L和127.67 gCO2e / MJ-生物柴油。考虑到直接的土地使用变化以及直接和间接的土地使用变化，相对于基准线，GHG排放量分别增加了3.5倍和8倍。麻疯树油的产量，生物柴油的产量和回收率以及麻疯树种子的生产率被认为是对生物柴油售价和相关温室气体排放量的最大影响因素。结果表明，在麻风树油产量为50 wt％的情况下，麻风树种子产量至少为3.9吨/公顷和5吨/公顷才能达到具有市场竞争力的生物柴油售价1美元/升，而温室气体排放量包括低于石油基准87.2 gCO2e / MJ的直接土地利用变化影响。避免林地受到干扰而有利于麻疯树造林是已确定的减少土地使用变化影响的战略之一。这些方法证明了在包括尼泊尔在内的许多国家中，解决当前挑战并发展环境和商业上可行的麻风树生物柴油产业的途径。
