In much of the public and policy debate, climate change is portrayed as an inevitable driver of large-scale human displacement. The notion of the “climate refugee” suggests a straightforward causal link: as global warming accelerates, more and more people will be forced to move. This narrative, however, risks oversimplifying a complex reality.
Recent research in migration studies has emphasized that climate change not only generates pressures to move, but also creates conditions of immobility. In other words, those most affected by environmental stress are not necessarily the ones who migrate. Instead, many become trapped in increasingly precarious situations – a phenomenon often described as involuntary immobility (Carling, 2002) or the immobility trap (Zickgraf, 2019).

Migration Requires Resources
Migration is rarely a cost-free survival strategy. Even in contexts of extreme stress, people require financial, social, and human capital to migrate (de Haas, 2010). Environmental degradation, such as prolonged droughts, crop failures, or flooding, often erodes precisely these resources. Families that might have considered internal or international migration in earlier generations may find themselves unable to cover the costs of transportation, visas, or recruitment fees.
This paradox has been highlighted by Black et al. (2011) in their influential framework on environmental change and migration: rather than producing a simple increase in displacement, climate impacts may both enable and constrain movement, depending on the availability of resources and networks.

Trapped Populations and Poverty Entrapment
The concept of trapped populations captures the reality that climate change can exacerbate poverty to the point of immobility. According to Foresight (2011), populations most exposed to environmental stress may paradoxically become the least mobile. This reflects what can be called poverty entrapment: rather than responding to environmental threats with migration, households are immobilized by a lack of options.
Zickgraf (2019) illustrates this in the Sahel, where recurrent droughts not only reduce agricultural yields but also undermine the ability of households to finance migration. Instead of out-migration increasing in response to climate stress, immobility persists – often accompanied by heightened vulnerability and insecurity.

Implications for Policy and Research
The assumption that climate change will lead to vast numbers of “climate refugees” risks obscuring this immobility dimension. International organizations may prepare for migration inflows while overlooking the silent crisis of those left behind. For policy, this suggests two critical implications:
1. Recognition of immobility as a policy concern: Just as displaced populations require support, so too do communities that are effectively trapped in deteriorating conditions.
2. Rethinking adaptation and resilience strategies: Instead of framing migration solely as a failure to adapt, it should be understood in the broader spectrum of mobility and immobility outcomes shaped by climate change.
⸻
Conclusion
Climate change does not mechanically equate to more migration. It produces differentiated outcomes: some people move, while others, often the most vulnerable, become immobilized. To grasp the full human impact of global warming, scholars and policymakers must address not only displacement, but also entrapment. Acknowledging this dual reality is vital to building fair and effective responses to the climate crisis.
