Migration and mobility are major characteristics of societies worldwide. The reasons for and pathways of migrations vary, as do perceptions of migration. Political debates are often organised normatively: the debate on the sustainable development goals presents migration foremost as a development issue resulting from global inequalities. The problems faced by particular migrants, and what a more sustainable approach to migration would look like are, therefore, often lost in political debates. We aim to address those gaps: the article conceptualizes, based on established academic debates, how sustainability in migration can be addressed systematically, which aspects are important for a more sustainable migration process and which trade-offs and injustices exist from several perspectives. We create a conceptual framework of sustainability in migration processes, building on the concepts of inter- and intragenerational justice, commonly accepted as the core of the sustainability concept. We apply this conceptual framework to empirical findings on labour migration and multilocality in Kyrgyzstan. The case enables consideration of the nested system effects of scale and translocality. This research is novel because it bridges the divided literature on migration, justice and sustainability, integrates theoretical and empirical insights and provokes a debate on which kind of migration we want to achieve.

移徙和流动是全球社会的主要特征。迁移的原因和途径以及对迁移的看法也各不相同。政治辩论通常是规范性的：关于可持续发展目标的辩论最主要地将移民问题视为由全球不平等引起的发展问题。因此，在政治辩论中常常忽视了特定移民所面临的问题以及采用什么样的更可持续的移民方式。我们旨在解决这些差距：本文基于既定的学术辩论，对如何系统地解决移民的可持续性进行了概念化，哪些方面对实现更可持续的移民过程至关重要，以及从多个角度来看存在哪些取舍和不公正之处。我们建立了跨代和代际正义概念的移徙过程中可持续性的概念框架，而跨代和代内正义概念通常被视为可持续性概念的核心。我们将此概念框架应用于关于吉尔吉斯斯坦劳务移民和多地区性的实证研究结果。这种情况可以考虑规模和跨位置嵌套系统的影响。这项研究是新颖的，因为它架起了关于移民，正义与可持续发展的各种文献的桥梁，融合了理论和经验方面的见解，并引发了关于我们想要实现哪种移民的辩论。我们将此概念框架应用于关于吉尔吉斯斯坦劳务移民和多地区性的实证研究结果。这种情况可以考虑规模和跨位置嵌套系统的影响。这项研究是新颖的，因为它架起了关于移民，正义与可持续发展的各种文献的桥梁，融合了理论和经验方面的见解，并引发了关于我们想要实现哪种移民的辩论。我们将此概念框架应用于关于吉尔吉斯斯坦劳务移民和多地区性的实证研究结果。这种情况可以考虑规模和跨位置嵌套系统的影响。这项研究是新颖的，因为它架起了关于移民，正义与可持续发展的各种文献的桥梁，融合了理论和经验方面的见解，并引发了关于我们想要实现哪种移民的辩论。
