Climate Hazards, Aspirations to Stay and Climate Immobility in Mozambique

For decades, a simple story has dominated how we think about climate change and human movement: when the weather turns dangerous, people pack up and leave. This view assumes that a severe storm, a rising sea, or a prolonged drought acts as a direct trigger, pushing families to migrate to safer ground. It is a linear way of thinking that treats staying behind as a failure of will or a lack of resources. However, a growing body of research challenges this assumption, suggesting that the reality is far more complex. Many people do not leave because they cannot, not because they do not want to. Others choose to remain, finding deep reasons to stay even as conditions worsen. This field of study, often called climate immobility, looks at why people are trapped, why they choose to stay, and what happens to those who are left behind when the environment becomes hostile. Understanding these reasons is crucial, because if policymakers only prepare for mass migration, they may fail to support the vast number of people who will remain in place, potentially leaving them vulnerable and invisible.

In the coastal city of Beira, Mozambique, researchers set out to test these ideas against the hard reality of daily life. Beira is a place where the threat of climate change is not a distant forecast but a current experience. The city faces a mix of sudden, violent events like tropical cyclones and floods, as well as slow, grinding changes like rising sea levels and saltwater creeping into fresh water sources. To understand how people here respond, a team of researchers from the University Joaquim Chissano and the Centre for Research on Governance and Development conducted a systematic survey. They spoke face-to-face with 416 residents across four different neighborhoods, ranging from informal settlements right on the edge of the bay to areas surrounded by rice fields. The goal was not just to ask who was moving, but to understand who was staying, why they were staying, and whether the climate hazards themselves were the main driver of that decision.

The findings from Beira overturn the conventional wisdom that disaster inevitably leads to departure. When the researchers asked residents about their future plans, a clear picture emerged: the majority are not moving. In fact, 65 percent of those surveyed said they are unable to leave, while 56 percent said they only plan to leave in the distant future. Half of the respondents stated they do not want to leave at all. Perhaps most strikingly, 46 percent said they would never leave their current homes, and 43 percent said they would remain even if the climate impacts continued to get worse. A significant portion of the population simply cannot imagine leaving. This data suggests that for most people in Beira, the idea of migration is not a primary response to climate danger. Instead, immobility is the dominant reality, whether that immobility is a forced trap or a voluntary choice.

To understand why, the researchers looked at the relationship between the climate hazards people faced and their decision to stay. They tested whether experiencing a cyclone, flooding, or rising temperatures made people more likely to move. The results were surprising: the climate hazards themselves had very little effect on whether people stayed or left. The statistical power of these environmental factors was almost negligible, explaining less than one percent of the variation in people's decisions. Instead, the strongest factor was something internal to the people themselves: their aspiration to stay. This is a deep-seated preference to remain in one's home community, driven by non-economic factors like attachment to place, family ties, cultural identity, and a sense of safety within the neighborhood. People who felt a strong commitment to their community, who saw a happy future there, or who felt their family needed them were far more likely to stay, regardless of the climate risks outside their door.

The study then dug deeper to identify what specifically fuels this desire to remain. The researchers tested five different explanations: the ability to stay, basic needs, adaptation strategies, human dignity, and the way different social factors like age and gender intersect. The results showed that the "capability to stay" and the fulfillment of "needs" were the most powerful drivers. Capability refers to having the resources and means to make life work in the current location. Those who felt they had enough money, savings, or family support to weather a crisis were more likely to aspire to stay. Similarly, the fulfillment of basic needs played a massive role. People who felt their homes were strong enough to withstand storms, that they had access to safe water and food, and that their children were protected were much more likely to want to remain. The quality of life and the belief that the future could be better through their own actions also mattered significantly.

Adaptation, or the ability to adjust to the changing climate without leaving, also played a role. People who had access to climate information, emergency warnings, and community support networks were better able to cope with hazards and thus more inclined to stay. However, the study found that the sense of human dignity and the specific vulnerabilities of different groups mattered less in this specific context. While the right to be treated with respect is fundamental, the data suggested that in Beira, the practical ability to survive and the meeting of basic needs were the primary reasons people chose to remain. The study also looked at how different identities combined to affect these choices. For instance, young women were found to be less likely to aspire to stay than other groups, perhaps because they see fewer prospects for their future in a vulnerable, impoverished setting. However, the specific combination of being poor and living in a particular informal settlement did not show a statistically significant effect on the decision to stay, suggesting that the drivers of immobility are complex and not easily reduced to a single demographic label.

The implications of these findings are profound for how we think about climate policy. If the prevailing assumption is that climate change will force everyone to move, then resources are funneled into relocation plans. But if the reality is that most people will stay, often because they are trapped by poverty or because they have a deep, resilient commitment to their home, then the focus must shift. The researchers argue that policymakers need to support "adaptation in place." This means investing in the very things that make staying possible: strengthening homes against floods, ensuring access to clean water and healthcare, and building the economic resources that allow families to survive shocks without having to flee. It also means respecting the right of people to choose to stay, rather than forcing them to move or ignoring them because they are not migrating.

The study also highlighted some unexpected twists in the data that complicate the picture. For example, while one might expect that having the "option" to stay would make people want to stay, the data showed the opposite: those who felt they had the option to stay were sometimes less likely to aspire to do so. This suggests that the mere availability of a choice is not enough; it is the actual capability to make that choice work that matters. Similarly, in a context where local governments sometimes force people out of vulnerable areas, those who are excluded from decision-making processes sometimes develop a stronger resistance to leaving, choosing to stay as a form of defiance or because they feel they have no other support. These nuances show that the decision to stay is not just a calculation of risk, but a complex interplay of hope, necessity, identity, and the specific political and social environment.

Ultimately, the story from Beira is one of resilience and constraint. It reveals that for the majority of people facing intensifying climate shocks, the future is not about packing a bag and leaving. It is about finding a way to endure where they are. The researchers found that while climate hazards are severe, they are not the primary reason people move or stay. Instead, the decision is driven by the capacity to survive, the fulfillment of basic human needs, and the deep, often unspoken bonds that tie people to their homes. By recognizing that immobility is a widespread and often voluntary or forced reality, rather than an anomaly, society can begin to build policies that actually protect the people who will remain on the front lines of a changing climate.
