Migration is increasingly viewed an adaptation strategy. Much of the migration-as-adaptation research applies a climate risk analytical lens, examining to what extent migration is a successful/adaptive response that reduces vulnerability or a failed/maladaptive response that increases vulnerability. However, this body of research has largely failed to examine migration outcomes through the eyes of those who migrate, thereby yielding insights that are potentially disconnected from their realities and desirable futures. To address this gap, this study focuses on the case of drought-in uenced migration from agro-pastoralist northern Kenya to the City of Nairobi. Applying a thematic analysis based on semi-structured interviews with 38 long-term migrants, we examine how migrants perceive 'success' and 'failure' in the context of migration as a response to the impacts of drought.The ndings show that migrants' success perceptions focus on the improvement of their families' economic security, namely ful lling their basic needs and reconstructing households' livelihood sources. Another related objective -supporting children's education -was often perceived as a means to shift the next generation out of agro-pastoralism, a perception that evolved in light of migrants' experiences in Nairobi. A similar failure theme pertains to migrants' inability to support their families. However, another predominant theme emphasizes self-failure, mainly as cultural assimilation in Nairobi. Associated with substance abuse and emotional disconnection from the north, assimilation was perceived as a potential trigger of cascading failures, including migrants' inability to achieve their adaptation-related objectives. As these ndings show, success and failure perceptions, including adaptation-related, are mediated by social-cultural factors and are intertwined with migrants' broader concerns and aspirations. As such concerns and aspirations may shape migrants' and households' vulnerability trajectories, research must shift from framing migration narrowly as a climate risk reduction strategy, to conceptualizing it as a process of navigating a landscape of desired and undesired outcomes.
