Climate change's direct and indirect effects on marine ecosystems and coastal areas mainly impact small-scale fishers, especially in developing countries, which present extreme poverty and high dependency on marine ecosystems as a source of food and sustenance for households. Understanding the vulnerability of fishing households and considering the associated socio-economic-political complexities is essential for preserving their livelihoods and maintaining their well-being. This study proposes a measure of economic vulnerability based on the capacity of fishing households in Tumaco, located on the southern Pacific coast of Colombia, to diversify their livelihoods. Different statistical procedures have been conducted to identify the most relevant strategies in reducing the economic vulnerability of households. The results indicate that reducing the vulnerability of fishing households depends on adaptation strategies such as occupational mobility, some elements of social capital, and reduced dependence on the fisheries resource. This study could constitute an input for creating public policy that guides efforts to achieve strategies for the generation of other livelihoods and the sustainability of fishing households that continue to choose fishing as their main economic activity.
气候变化对海洋生态系统和沿海地区的直接和间接影响主要冲击小规模渔民，尤其是在发展中国家，这些国家存在极端贫困且高度依赖海洋生态系统作为家庭的食物和生计来源。了解渔业家庭的脆弱性并考虑相关的社会经济政治复杂性对于维护他们的生计和保持他们的福祉至关重要。本研究基于哥伦比亚太平洋沿岸南部图马科渔业家庭的生计多样化能力，提出了一种经济脆弱性衡量方法。已经进行了不同的统计程序，以确定减少家庭经济脆弱性的最相关策略。结果表明，降低渔业家庭的脆弱性取决于适应策略，如职业流动、社会资本的一些要素以及减少对渔业资源的依赖。本研究可为制定公共政策提供参考，该政策指导努力实现创造其他生计的策略以及继续选择捕鱼作为主要经济活动的渔业家庭的可持续性。
