Weather patterns shape both human settlement and mobility. Weather-related disasters, like Hurricane Katrina in the Gulf Coast, can displace millions overnight. Gradual weather changes can trigger migration out of regions dependent on rain-fed agriculture. These weather shifts are expected to intensify with anthropogenic climate change and contribute to large scale human mobility. This panel will consider the impact of sudden or slow-onset environmental changes on human migration and subsequent patterns of inequality. The panel will also include research on mechanisms linking environmental factors to mobility, such as agricultural productivity, food security, and conflict. The goal of the panel is to establish inter-disciplinary dialogue on the question; therefore, we encourage submissions from any discipline using any method (qualitative, quantitative, historical, experimental, etc).
