Hundreds of thousands of migrants have left Central America in recent years, and climate extremes have been identified as one of the factors that might be driving this movement, along with elements such as political instability and violence. In this episode, we hear from geographer and climatologist Diego Pons, of Colorado State University, to dissect how changing climate, food insecurity, and migration intersect in this region.

Among the earliest examples of the disruptions that climate change can bring, some low-lying island countries in the Pacific Ocean are facing serious threats from rising sea levels and coastal erosion. Over the long term, atoll nations such as Kiribati, Tuvalu, and the Marshall Islands might eventually need to relocate some or all of their populations. But not everyone wants to migrate, and governments have balanced supporting people who relocate with other ways of adapting to changing conditions. Carol Farbotko, of Australia’s University of the Sunshine Coast and the University of Tasmania, joins the podcast to discuss the policies and dynamics in place in this region.

Confronting environmental change, whole communities sometimes relocate from one area to another. This purposeful, coordinated movement, while currently rare, is referred to as managed retreat. In this episode Architesh Panda, from the London School of Economics’ Grantham Research Institute on Climate Change and the Environment, explains how this climate adaptation strategy works in India.

The relationship between climate change and migration is long and complex. Human civilizations have been affected by environmental conditions for centuries, but we should be wary of arguments that huge numbers of people are inevitably destined to migrate in response to specific climate threats. In this episode, we chat with Alex de Sherbinin of Columbia University’s Center for International Earth Science Information Network about what the research shows – and doesn’t show.

While climate change and migration remain high on political agendas in Europe, the exact link between the two remains uncertain. Without clarity on how different climate events might lead to more human mobility (or conversely, immobility), it is difficult for migration policymakers and development actors to align their efforts and ensure they are spending resources wisely. Investments in climate adaptation, for instance, which aim to build communities’ resilience to cope with environmental stress, have only recently begun to take human mobility into account. And so far, adaptation activities make up only a small part of Europe’s formidable climate spending.

The COVID-19 pandemic only adds to the urgency of finding innovative financing tools for climate adaptation and migration. Many of the adaptation strategies policymakers previously applied to support communities affected by sudden-onset floods or slow-onset desertification are now obsolete, for example as physical distancing requirements have complicated evacuation and relocation. And because the issue cuts across different policy portfolios, it is difficult to assign clear responsibilities. 

This MPI Europe discussion, with MPI Europe's Hanne Beirens, University of Liège's François Gemenne, GIZ's Dorothea Rischewski, and the European Investment Bank's Moa Westman, explored different migration policy options related to climate adaptation and the evolving landscape of climate finance tools. Speakers also examined what funding gaps and opportunities exist for collaboration with partner countries and what funding instruments might address the most pressing needs. The conversation also explored the implications of COVID-19 for migration and climate adaptation funding approaches.

This MPI event, in partnership with the International Organization for Migration (IOM), discusses the critical issue of climate-related displacement in the Asia-Pacific region, explored in depth in the joint MPI and IOM brief Human Rights, Climate Change, Environmental Degradation and Migration: A New Paradigm. Climate change and environmental degradation are predicted to displace millions of people in the coming years, either directly or indirectly. While today’s international legal framework provides a degree of protection to those displaced by environmental factors and climatic events, there is no global consensus on a definition for such a group. In the absence of this, gaps in the legal system, and in implementation, how can recognition of the vulnerability of environmental migrants be facilitated and their protection ensured? This discussion explores how to protect climate change-induced migrants, particularly in the highly vulnerable Asia-Pacific region.
