Small-scale biodiesel production with a high level of community involvement has been associated with a number of benefits. These include relatively low environmental impacts, lack of competition with food production, strong poverty alleviation effects and enhanced access to energy. This Short Communication provides a qualitative analysis of the effects of the cultivation of biodiesel oilseed tree crops (mostly Millettia pinnata, along with Simarouba glauca, Azadirachta indica, Madhuca lungifolia and Jatropha curcas) in such a small-scale project, the Hassan Bio-Fuel Park in Karnataka, India. This extensive ethnographic research and using the ecosystem services approach to synthesize the findings suggests that the changes in both the flows of ecosystem services and different constituents of human wellbeing are marginal. While the ecosystem services approach can be useful to synthesize various forms of knowledge on biofuels to inform policy, this particular case study highlights the importance of being open about the different, often implicit, priorities and values of research projects and the various kinds of actors involved in biofuel production. Finally, it is crucial to understand not just which impacts are generated but especially how those impacts are generated.

社区参与程度很高的小规模生物柴油生产已带来许多好处。其中包括相对较低的环境影响，与粮食生产缺乏竞争，强大的扶贫效果以及增加的能源获取。本简短交流提供了生物柴油油料种子作物（主要是Millettia pinnata以及Simarouba glauca，Azadirachta indica，Madhuca lungifolia和Jatropha curcas）种植效果的定性分析。）是一个小型项目，位于印度卡纳塔克邦的哈桑生物燃料公园。这项广泛的民族志研究并使用生态系统服务方法来综合研究结果，这表明生态系统服务流量和人类福祉的不同组成部分的变化都是微不足道的。尽管生态系统服务方法可用于综合各种形式的生物燃料知识以为政策提供信息，但这一特殊案例研究凸显了对研究项目以及所涉及的各种参与者的不同，通常是隐含的优先事项和价值持开放态度的重要性。在生物燃料生产中。最后，至关重要的是不仅要了解会产生哪些影响，而且尤其要了解这些影响是如何产生的。
