Coastal zones are complex systems where sustainability needs local participative governance, whose absence may result in conflicts between social actors. In its absence, the first step should be a diagnosis of the current situation based on integrative conceptual frameworks such as the DPSIR. However, in conflicting situations, the generated model needs validation from social actors. Chiloé Island is a critical Chilean coastal fishery and aquaculture area, coexisting with subsistence and cultural uses of marine resources. This article analyzes the current ecological state of the Chiloé coastal zone and its main social-ecological impact using a DPSIR model. We validated its results through a household survey and interviews with local experts and social actors. Results show that increased coastal fisheries and aquaculture generate a critical decrease of coastal species, eutrophication, and pollution that, along with harmful algal blooms, generate conflicts. Social validation showed that experts and local social actors have different perceptions of conflicting parties and conflict solutions. Following a post-normal approach, we propose three ideas to start social-ecological governance of Chiloé coastal marine ecosystems.

沿海地区是复杂的系统，其中可持续性需要地方参与式治理，而缺乏这种参与可能会导致社会行为者之间发生冲突。如果没有，第一步应该是基于诸如DPSIR之类的综合概念框架对当前情况进行诊断。但是，在冲突的情况下，生成的模型需要社会参与者的验证。奇洛埃岛是智利重要的沿海渔业和水产养殖区，与海洋资源的生存和文化利用并存。本文使用DPSIR模型分析了Chiloé沿海地区的当前生态状况及其主要的社会生态影响。我们通过家庭调查以及与当地专家和社会行为者的访谈来验证了其结果。结果表明，沿海渔业和水产养殖业的增长导致沿海物种，富营养化和污染的严重减少，这与有害藻华一起引发冲突。社会验证表明，专家和当地社会行为者对冲突方和冲突解决方案的看法不同。遵循正常后的方法，我们提出了三个想法来开始对Chiloé沿海海洋生态系统进行社会生态治理。
