Research shows that environmental shocks can influence migration. However, studies vary widely in the shocks and type of migration measured, the context, and the strength and direction of environmental effects. In addition, existing theories provide opposing predictions for this relationship. There is a clear need for further theoretical development in the climate-migration literature. This study, in rural Nepal, examines four types of weather shocks, over various time frames, on four types of migration. Results suggest that the most substantial influence of weather shocks is not in a wholesale increase or decrease in migration. Instead, weather shocks are related to changes in the type of migration used, resulting in less long-term and more short-term migrations in the population. We use the ready-willing-and-able perspective to make sense of these patterns.

尼泊尔天气冲击和移民的时空维度

研究表明，环境冲击会影响移民。然而，研究在冲击和测量的迁移类型、背景以及环境影响的强度和方向方面差异很大。此外，现有理论对这种关系提供了相反的预测。气候迁移文献显然需要进一步的理论发展。这项在尼泊尔农村开展的研究调查了四种类型的移民在不同时间范围内的四种天气冲击。结果表明，天气冲击的最大影响不是迁移的整体增加或减少。相反，天气冲击与所使用的迁移类型的变化有关，导致人口中长期迁移减少而短期迁移增加。
