对移徙作为对气候变化的一种反应进行的研究主要集中在农村地区,而没有考虑到城市地区。鉴于城市居民人数众多和持续的高水平城市化,缺乏对城市的关注是令人遗憾的。为了填补这一经验空白,本研究调查了1986-1999年气候变化对墨西哥农村和城市向美国移民的影响。我们采用地统计插值方法来构建两个气候变化指数,捕捉温暖和潮湿的持续时间,根据墨西哥214个气象站的每日温度和降水量读数。结合从墨西哥移民项目获得的详细移民历史,我们模拟了气候变化对68个农村和49个城市的家庭移民的影响。多级事件历史模型的结果表明,研究期间气温变暖和降水过多显着增加了国际移民。然而,气候变化对国际移徙的影响仅在农村地区观察到。相互作用揭示了一个因果路径,其中温度(而不是降水)通过农业部门的就业影响移徙模式。因此,与气候有关的国际移徙可能会随着城市化的持续以及家庭对农村农业的直接依赖的减少而减少。
Studies investigating migration as a response to climate variability have largely focused on rural locations to the exclusion of urban areas. This lack of urban focus is unfortunate given the sheer numbers of urban residents and continuing high levels of urbanization. To beginfilling this empirical gap, this study investigates climate change impacts on US-bound migration from rural and urban Mexico, 1986–1999. We employ geostatistical interpolation methods to construct two climate change indices, capturing warm and wet spell duration, based on daily temperature and precipitation readings for 214 weather stations across Mexico. In combination with detailed migration histories obtained from the Mexican Migration Project, we model the influence of climate change on household-level migration from 68 rural and 49 urban municipalities. Results from multilevel event-history models reveal that a temperature warming and excessive precipitation significantly increased international migration during the study period. However, climate change impacts on international migration is only observed for rural areas. Interactions reveal a causal pathway in which temperature (but not precipitation) influences migration patterns through employment in the agricultural sector. As such, climate-related international migration may decline with continued urbanization and the resulting reductions in direct dependence of households on rural agriculture.
