学者和活动家假设环境变化与人口外流之间存在联系。在本文中，我们使用尼泊尔的数据检验了这一假设。我们通过土地覆盖减少、收集有机投入所需时间增加、人口密度增加以及农业生产力感知下降等方面来实施环境变化。一般来说，环境变化与短距离移动的相关性比长距离移动的相关性更强。保持其他社会和经济变量的影响不变，我们发现局部迁移是通过感知的生产力下降、土地覆盖面积减少和收集柴火所需时间增加来预测的。长途流动是通过感知生产力下降来预测的，但其效果弱于短距离流动模型。我们还表明，环境变化的影响因性别和种族而异，女性更容易受到收集饲料所需时间变化的影响，而男性则更容易受到收集柴火时间变化的影响，而高种姓印度教徒通常比其他人受环境变化的影响较小。
Scholars and activists have hypothesized a connection between environmental change and out-migration. In this paper we test this hypothesis using data from Nepal. We operationalize environmental change in terms of declining land cover, rising times required to gather organic inputs, increasing population density, and perceived declines in agricultural productivity. In general, environmental change is more strongly related to short- than long-distance moves. Holding constant the effects of other social and economic variables, we find that local moves are predicted by perceived declines in productivity, declining land cover, and increasing time required to gather firewood. Long-distance moves are predicted by perceived declines in productivity, but the effect is weaker than in the model of short-distance mobility. We also show that effects of environmental change vary by gender and ethnicity, with women being more affected by changes in the time required to gather fodder and men by changes in the time to gather firewood, and high caste Hindus generally being less affect than others by environmental change.
