摘要

长期以来,研究人员一直假设气候变化、粮食安全与中低收入国家(LMICs)的移民之间存在联系。其中一个假设是 "农业途径",它假定气候变化对粮食生产的负面影响会损害生计,从而引发农村人口向国内或国外迁移。因此,移民是应对气候变化影响和改善生计的一种适应手段。最近的证据表明,农业途径是解释与气候有关的移民的一个合理机制。但是,从气候对粮食生产的影响到生计损失再到农村人口向外迁移的直接因果关系尚未完全确定。为指导今后有关气候-粮食-移民关系的研究,我们提出了一个概念框架,概述了低收入和中等收入国家农业途径的组成部分和联系。我们以已有的环境-移民概念框架为基础,这些框架为实证研究提供了依据,加深了我们对复杂的人类-环境系统的理解。首先,我们概述了这一概念框架及其与气候流动性文献中的农业路径假设之间的联系。然后,我们概述了概念框架中与低收入和中等收入国家相关的主要组成部分和联系,强调了当前与农业途径相关的研究差距和挑战。最后,我们讨论了气候-粮食-移民关系未来可能的研究方向。通过强调农业途径所包含的复杂、多尺度、相互关联的联系,我们的框架揭示了目前隐藏在农业途径假设中的多种因果联系。

A framework to link climate change, food security, and migration: unpacking the agricultural pathway

A framework to link climate change, food security, and migration: unpacking the agricultural pathway

Researchers have long hypothesized linkages between climate change, food security, and migration in low- and middle-income countries (LMICs). One such hypothesis is the “agricultural pathway,” which postulates that negative climate change impacts on food production harm livelihoods, which triggers rural out-migration, internally or abroad. Migration is thus an adaptation to cope with the impacts of climate change and bolster livelihoods. Recent evidence suggests that the agriculture pathway is a plausible mechanism to explain climate-related migration. But direct causal connections from climate impacts on food production to livelihood loss to rural out-migration have yet to be fully established. To guide future research on the climate-food-migration nexus, we present a conceptual framework that outlines the components and linkages underpinning the agricultural pathway in LMICs. We build on established environmental-migration conceptual frameworks that have informed empirical research and deepened our understanding of complex human-environmental systems. First, we provide an overview of the conceptual framework and its connection to the agricultural pathway hypothesis in the climate mobility literature. We then outline the primary components and linkages of the conceptual framework as they pertain to LMIC contexts, highlighting current research gaps and challenges relating to the agricultural pathway. Last, we discuss possible future research directions for the climate-food-migration nexus. By highlighting the complex, multiscale, interconnected linkages that underpin the agricultural pathway, our framework unpacks the multiple causal connections that currently lie hidden in the agricultural pathway hypothesis.
