Professional fishing activities are subject to spatial pressures. The cohabitation between a traditional fishing activity and development of the offshore wind energy industry raises questions about space sharing and rules of use. This paper proposes to adapt the vulnerability methodology developed to deal with global threats of climate change to this example of local, non-climatic change using the case study of a floating wind turbine project between Groix and Belle-Île (France). To understand and compare the potential impact of the different artisanal fishing activities, the method aims to conceptualize vulnerability with the identification of social, economic, and environmental key pressures and address them in a composite index. Although the smallest fishing units appear to be the most vulnerable, this effect is associated with a high sensitivity to the area near the coast. This research also highlights the importance of transparency and clarity during the construction of the composite index to avoid misinterpretation. This case study supports the relevance of applying the vulnerability method on a local scale to facilitate dialogue between stakeholders and reduce negotiation costs.

专业捕鱼活动受到空间压力。传统捕鱼活动与海上风能产业发展的共存引发了关于空间共享和使用规则的问题。本文建议使用 Groix 和 Belle-Île（法国）之间的浮动风力涡轮机项目的案例研究，调整为应对全球气候变化威胁而开发的脆弱性方法，以适应当地的非气候变化示例。为了了解和比较不同手工捕鱼活动的潜在影响，该方法旨在通过识别社会、经济和环境关键压力来概念化脆弱性，并在综合指数中解决它们。尽管最小的捕捞单位似乎最脆弱，这种影响与对海岸附近地区的高度敏感有关。本研究还强调了在综合指数构建过程中透明度和清晰度的重要性，以避免误解。该案例研究支持在当地范围内应用脆弱性方法以促进利益相关者之间的对话并降低谈判成本的相关性。
