生物燃料作物被认为是化石能源的气候友好型替代品。然而，诸如潜在的生物多样性丧失等环境风险并不总是得到充分考虑。这可能是土地利用从自然系统转变为生物燃料种植园的直接结果，但也可能是生物燃料物种的入侵行为，因为它可能分散并建立到邻近的自然系统中。因此，有必要进行事前入侵风险评估，包括在大规模推广和扩展新的生物燃料物种之前对其进行实地试验。这个视角使用麻风树。作为一种典型的生物燃料作物，综述了其生物特性和可能导致其入侵行为的环境因素。curcasa作为一种生物柴油的“神奇作物”最近受到了很多关注，并且在没有对其入侵风险进行科学研究的情况下被大规模种植。我们应用了两种风险评估框架来提供事前侵入性风险评估。Curcasis是一种具有高入侵风险的物种，这与最近的实验证据相矛盾。我们讨论了现有风险评估框架的局限性，这可能导致不可靠的预测。我们对这一理论实践的结果进行了解释，并对j的选择、引种、栽培和加工阶段提出了一些建议。番石榴和其他生物燃料作物，以尽量减少入侵风险。最后，我们指出了投资者和政府的责任，以及对整个生物燃料生产供应链进行综合研究以避免生物入侵的必要性。©2013化学工业协会和约翰威利父子有限公司
Biofuel crops are promoted as a climate friendly alternative to fossil energy. Yet environmental risks such as potential biodiversity loss are not always adequately considered. This might occur directly as a consequence of land‐use change from natural systems to biofuel plantations, but also through invasive behavior of the biofuel species, as it might disperse and establish into adjacent natural systems. Therefore, there is a need to perform ex‐ante invasiveness risk assessments including field trials on new biofuel species before they get promoted and expanded on a large scale. This perspective usesJatropha curcasL. as a model biofuel crop and reviews the biological traits and the circumstantial factors which may contribute to its invasive behavior.J. curcashas recently received much attention as a biodiesel ‘wonder crop’ and is being planted at large scale without scientific study on its invasiveness risk. We applied two risk assessment frameworks to provide an ex‐ante invasiveness risk assessment and obtained thatJ. curcasis a species with a high invasiveness risk, which is in contradiction with recent experimental evidence. We discuss the limitations of the available risk assessment frameworks, which may have led to unreliable prediction. We interpret the outcome of this theoretical exercise with some recommendations for the selection, introduction, cultivation, and processing stages ofJ. curcasand other biofuel crops to minimize invasiveness risk. Finally we point to the responsibilities of investors and governments and the need for integrated research of the whole biofuel production supply chain to avoid bio‐invasions. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd
