全球农村家庭将移民和自然资源利用作为旨在满足家庭需求的生计战略的组成部分。然而，移民学者最近才开始定期将环境因素纳入实证建模工作中。为了研究南非农村地区的移民与环境之间的关联，我们使用了卫星图像中的植被测量值以及阿金库尔健康和人口监测站点 9000 多个家庭的详细人口数据。结果显示，家庭层面的临时移民与当地较高水平的自然资本相关，但永久移民不存在这种关联。此外，更有利的家庭在移民与环境之间表现出更强的关联，这与“环境资本”假设相符，表明自然资源的可用性可以促进家庭收入多元化。我们认为，在当今气候变化的时代，对移民环境方面的关注尤为及时，自然资本的可用性和可变性代表了实证移民难题的关键部分，特别是在周期性生计移民方面。版权所有 © 2013 约翰·威利父子有限公司
Rural households across the globe engage in both migration and natural resource use as components of livelihood strategies designed to meet household needs. Yet, migration scholars have only recently begun to regularly integrate environmental factors into empirical modelling efforts. To examine the migration‐environment association in rural South Africa, we use vegetation measures derived from satellite imagery combined with detailed demographic data from over 9000 households at the Agincourt Health and Demographic Surveillance Site. Results reveal that household‐level temporary migration is associated with higher levels of local natural capital, although no such association exists for permanent migration. Further, more advantaged households exhibit a stronger association between migration‐environment, in‐line with the ‘environmental capital’ hypothesis, suggesting that natural resource availability can facilitate household income diversification. We argue that a focus on migration's environmental aspects is especially timely in the contemporary era of climate change and that natural capital availability and variability represent critical pieces of the empirical migration puzzle, especially regarding cyclical livelihood migration.
