Some chemical herbicides used by farmers in Martinique contaminate rivers. Agroecological innovations exist, some of which are known by the stakeholders but are not systematically used at the scale of the watersheds concerned. Our hypothesis is that the sociotechnical agricultural supply chain system built over the last 30 years restricts innovations for herbicide use in weed management systems, blocking the sustainable transition of territories. The sociotechnical system theory was chosen as the analysis framework to identify obstacles in supply chains. As the issue cut across the supply chains at the scale of the territory, this framework was completed, for the first time, by a study of the existing links between supply chain innovation strategies and the territory through its spatial, organisational and conceptual dimensions. Interviews with supply chain actors and a review of the grey literature were analysed using this framework. We show that the development of innovations, their type and the network of actors producing them were defined within each supply chain, according to their own objectives, with few exchanges at all levels of the territory. The efficiency of such development depended on the extent to which the supply chains are structured and, particularly, on their degree of integration and the strength of relationships between stakeholders. Indeed, watershed scale objectives are not taken into consideration in changes of practice. In this way, we identified lock-in constraining innovations design taking into account the objectives of the impact area (watershed) across supply chains for the first time.

供应链中的创新阻碍了地区生态转型：马提尼克岛的一个分水岭

马提尼克岛农民使用的一些化学除草剂污染了河流。存在农业生态创新，其中一些利益相关者知道，但并未在相关流域范围内被系统地使用。我们的假设是，过去30年建立的社会技术农业供应链系统限制了杂草管理系统中除草剂使用的创新，从而阻碍了领土的可持续过渡。选择社会技术系统理论作为分析框架，以确定供应链中的障碍。当问题遍及整个领土的供应链时，该框架首次通过研究其空间，组织和概念维度对供应链创新战略与领土之间的现有联系进行了完善。使用此框架分析了与供应链参与者的访谈和对灰色文献的评论。我们表明，创新的发展，创新的类型和产生创新的参与者的网络是根据其自身的目标在每个供应链中定义的，在该地区的各个层次上很少进行交流。这种发展的效率取决于供应链的结构程度，尤其取决于它们的整合程度和利益相关者之间的关系强度。实际上，在实践变更中并未考虑分水岭规模目标。通过这种方式，我们首次确定了锁定约束创新设计，同时考虑了整个供应链中影响区域（分水岭）的目标。
