Rapid soybean expansion in South America has been linked to numerous socio-environmental problems, including deforestation in sensitive biomes. As a major importing region of soybeans, wider public awareness has also put pressure on the European Union. Different governance initiatives involving various groups of stakeholders have sought to address these issues. However, what is identified as a relevant problem, as a region of interest or which actors are mentioned in this context are all matters of claims-making processes between different groups and mediated through various channels of communication. This study uses a text-mining approach to trace the construction of socio-ecological problems related to soybean expansion and the actors and regions linked with these issues in public discourse. The focus lies on print media from the European Union, but several additional sources are included to investigate the similarities and differences between various communication channels and regions. These include newspaper articles from producing countries and international news agencies, scientific abstracts, corporate statements, and reports from advocacy groups gathered from the mid-1990s to 2020. The results show that European mass media have shifted their focus from consumer labeling, health, and concerns over genetically modified organisms towards more distant or abstract phenomena, such as deforestation and climate change. This has been accompanied with a broader view on different stakeholders, but also with a strong regional focus on the Amazon biome. There has also been much less attention on direct concerns for communities in producing regions, such as land conflicts or disputes over intellectual property rights. We conclude that while European public spheres appear to become more receptive to issues related to impacts in sourcing regions, there remains a narrow focus on specific problems and regions, which reflects a fundamental asymmetry in different stakeholders' ability to shape transnational deliberations and resulting governance processes.

南美洲大豆的快速扩张与许多社会环境问题有关，包括敏感生物群落中的森林砍伐。作为大豆的主要进口地区，更广泛的公众意识也给欧盟带来了压力。涉及不同利益相关者群体的不同治理举措试图解决这些问题。然而，什么被确定为相关问题，作为一个感兴趣的区域或在这种情况下提到哪些行为者，都是不同群体之间的声明过程的问题，并通过各种沟通渠道进行调解。本研究使用文本挖掘方法来追踪与大豆扩张相关的社会生态问题的构建，以及在公共话语中与这些问题相关的参与者和地区。重点是来自欧盟的印刷媒体，但还包括几个额外的来源，以调查各种沟通渠道和地区之间的异同。其中包括来自生产国和国际新闻机构的报纸文章、科学摘要、公司声明以及从 1990 年代中期到 2020 年收集的倡导团体的报告。结果表明，欧洲大众媒体已将关注重点从消费者标签、健康和对转基因生物对更遥远或更抽象的现象的担忧，例如森林砍伐和气候变化。这伴随着对不同利益相关者的更广泛的看法，但也有对亚马逊生物群落的强烈区域关注。对产区社区直接关注的关注也少得多，如土地纠纷或知识产权纠纷。我们得出的结论是，虽然欧洲公共领域似乎更容易接受与采购地区影响相关的问题，但对特定问题和地区的关注仍然很窄，这反映了不同利益相关者塑造跨国审议和由此产生的治理过程的能力的根本不对称.
