Migration is one of the variety of ways by which human populations adapt to environmental changes. The study of migration in the context of anthropogenic climate change is often approached using the concept of vulnerability and its key functional elements: exposure, system sensitivity, and adaptive capacity. This article explores the interaction of climate change and vulnerability through review of case studies of dry-season migration in the West African Sahel, hurricane-related population displacements in the Caribbean basin, winter migration of 'snowbirds' to the US Sun-belt, and 1930s drought migration on the North American Great Plains. These examples are then used as analogues for identifying general causal, temporal, and spatial dimensions of climate migration, along with potential considerations for policy-making and future research needs.
迁移是人类群体适应环境变化的多种方式之一。在人为气候变化背景下对迁移的研究,通常采用脆弱性概念及其关键功能要素:暴露度、系统敏感性和适应能力。本文通过回顾西非萨赫勒地区旱季迁移、加勒比海盆地与飓风相关的人口流离失所、“雪鸟”向美国阳光地带的冬季迁移以及北美大平原20世纪30年代干旱迁移的案例研究,探讨气候变化与脆弱性之间的相互作用。这些例子随后被用作类比,以确定气候迁移的一般因果、时间和空间维度,以及政策制定的潜在考虑因素和未来研究需求。
