Individual mobility – moving between and within different geographic regions – represents an adaptation strategy of natural resource users worldwide to cope with sudden and gradual changes in resource abundances. This work traces the recent history of Peruvian small-scale fishers’ migration, and particularly analyses the spatial mobility patterns of resource users along the Peruvian coastline in the aftermath of the coastal El Niño 2017. In February-March 2017, this event caused extraordinary heavy rains and a rise in water temperatures along the coast of northern Peru, inducing negative consequences for the small-scale fisheries and scallop (Argopecten purpuratus) aquaculture sectors, both representing important socio-economic activities in the region. Responses of local resource users to these changes were highly diverse, with a great number of people leaving the region in search for work in fishing and non-fishing activities. With a particular emphasis on the province of Sechura, this work attempts to shed light on how and why migration flows differ for fishers and scallop farmers and to explore future pathways in the context of post-disturbance recovery. About one year after the disturbance event, the small-scale fishery operated almost on a regular scale, while the aquaculture sector still struggled towards pre-El Niño conditions, reflected, for example, in a higher percentage of persons engaging in other economic activities within and outside the region. The results of this study demonstrate the importance of human movement and translocal social networks emerging in moments of crisis and should be considered for future development of long-term management strategies incorporating increasing interconnectedness of places on different scales in the face of future disturbance events. Understanding adaptation strategies of resource users in this particular social-ecological setting will further serve to inform other coastal systems prone to (re-occurring) environmental change by highlighting the diversity of socio-economic and natural drivers that can stipulate mobility and affect adaptive capacity of resource users.

个体流动性（在不同地理区域之间和之内移动）代表着全球自然资源使用者的适应策略，以应对资源丰度的突然和逐渐变化。这项工作追溯了秘鲁小规模渔民移徙的最新历史，尤其是分析了2017年厄尔尼诺现象沿海之后秘鲁海岸线上资源使用者的空间流动方式。2017年2月至3月，这一事件造成了沉重的负担降雨和秘鲁北部沿海水温上升，对小型渔业和扇贝产生负面影响（Argopecten purpuratus）水产养殖部门，均代表该地区重要的社会经济活动。当地资源使用者对这些变化的反应高度多样化，有大量人离开该地区寻找捕鱼和非捕鱼活动的工作。这项工作特别着重于Sechura省，试图揭示出移民流向渔民和扇贝农民的方式和原因如何以及为何在干扰后恢复的背景下探索未来的途径。扰乱事件发生后约一年，小型渔业几乎按常规规模经营，而水产养殖部门仍在向厄尔尼诺现象之前挣扎，例如，反映出在该地区从事其他经济活动的人比例较高和该地区以外。这项研究的结果表明了在危机时刻出现的人类运动和跨地区社会网络的重要性，并应考虑将长期管理策略的未来发展纳入考虑范围，以应对未来骚扰事件中不同规模场所之间日益增加的相互联系。理解在这种特定社会生态环境下资源使用者的适应策略，将通过强调社会经济和自然驱动因素的多样性，从而规定流动性并影响其适应能力，从而进一步为其他容易（反复发生）环境变化的沿海系统提供信息。资源用户。
