Field data (interviews and workshop results) Clean Shipping project

Data from field visits in Spain, Colombia, and Namibia (interview transcripts and workshop results) for the Clean Shipping project. The project aimed to design and develop inclusive and sustainable value chains for marine biofuels. We conducted field research in three locations with potential for new bio-based value chains. The cases included olive oil residues in Jaen, Spain, coffee and cocoa residues in the coffee axis in Colombia, and encroacher bush in Namibia. Fieldwork consisted of semi-structured interviews with stakeholders that could play a potential role in the new value chain, to understand the current system, their challenges, their possible roles, as well as opportunities and hurdles for establishing a new value chain. Moreover, more in-depth interviews were conducted with small-scale farmers about their challenges, needs, capabilities, and desires. In addition, multi-stakeholder workshops were organized to discuss ideal scenarios and a roadmap to achieve those scenarios, together with different local stakeholders. Data was collected between 2021 and 2023, the researchers stayed 6 weeks in the field in each location. The data set consists of anonymized English transcripts of the interviews and summaries of the workshop conclusions.本数据集源自清洁航运（Clean Shipping）项目在西班牙、哥伦比亚及纳米比亚开展的实地调研数据，涵盖访谈转录稿与研讨会成果。该项目旨在设计并开发面向海洋生物燃料（marine biofuels）的包容性可持续价值链。研究团队在三处具备发展新型生物基价值链潜力的地点开展了实地研究，具体案例包括西班牙哈恩（Jaen）地区的橄榄油残渣、哥伦比亚咖啡带的咖啡与可可残渣，以及纳米比亚的入侵灌丛（encroacher bush）。实地调研包含与潜在参与新型价值链构建的利益相关者开展的半结构化访谈，旨在了解当前产业体系、各方面临的挑战、可承担的角色，以及构建新型价值链的机遇与阻碍。此外，研究团队还针对小规模农户开展了更深入的访谈，以了解其面临的挑战、需求、能力与发展意愿。另外，研究团队联合当地各类利益相关者组织了多利益相关方研讨会，共同探讨理想发展场景及实现该场景的路线图。数据采集工作于2021年至2023年间开展，研究人员在每个调研地点驻场调研6周。本数据集包含经匿名化处理的英文访谈转录稿，以及研讨会结论摘要。
