How nature-based solutions support mobility as an adaptation strategy
This study analyzes 60 interviews in Sub-Saharan Africa to reveal that Nature-based Solutions (NbS) function as a critical climate adaptation strategy not merely by influencing whether people migrate, but by reshaping community aspirations, capabilities, and environmental literacy through nine distinct mobility personas.

When the climate shifts, people move. This is a simple truth, but the story of how and why is far more complex than the headlines often suggest. For decades, the dominant narrative has been one of mass exodus: that rising seas and drying lands force entire populations to flee their homes in a desperate, linear rush toward safety. Yet, in the real world, human movement is rarely so straightforward. It is a tangled web of choices, where staying put can be just as strategic as leaving, and where moving temporarily might be the key to long-term survival. This is the realm of climate mobility, a field that looks at how environmental changes interact with a person's hopes, their resources, and their deep ties to a specific place.
In this context, a new approach has gained attention: Nature-based Solutions. These are actions that work with nature rather than against it, such as restoring mangrove forests to buffer storms, planting trees to hold soil in place, or managing water systems to survive droughts. The idea is that by healing the land, we can heal the communities living on it. But a critical question remains unanswered: does fixing the environment actually change how people decide to move? Does planting a tree make someone stay, or does it give them the confidence to leave and try their luck elsewhere? A recent study set out to answer this by listening to the stories of people living in some of the most climate-vulnerable regions of Africa.
The research, conducted across seven diverse sites in five Sub-Saharan African countries, involved sitting down with sixty community members who were actively engaged in these nature-based projects. Instead of asking them to fill out surveys with checkboxes, the researchers asked them to tell their stories. They wanted to know how these environmental projects influenced the decision to leave, to stay, to return, or to move seasonally. The team listened to sixty distinct narratives, looking for the patterns that emerged when people described their lives, their livelihoods, and their relationship with the land.
What they found challenged the simple idea that nature projects simply keep people in place or force them out. The study revealed that nature-based solutions do not act as a switch that flips a decision from "stay" to "go." Instead, they act more like a lens, reshaping how people see their future possibilities. The researchers identified nine distinct "personas," or recurring types of stories, that showed how these projects changed the lives of the people involved. These stories fell into three broad categories: those where nature projects helped people move successfully, those where they helped people stay safely, and those where the projects were not enough to prevent a difficult outcome.
In one group of stories, nature-based solutions acted as a foundation for new opportunities. People described how restoring ecosystems created new jobs in farming, fishing, or conservation, giving them the skills and income to build a better future. For some, this meant staying in their home villages because the land now offered a viable livelihood. For others, the confidence and resources gained from these projects gave them the freedom to move to a new place to pursue those same opportunities. In these cases, the project didn't dictate the direction of travel; it expanded the range of choices available.
Another set of stories showed how these solutions helped people adapt right where they were. Some communities, facing recurring floods or droughts, used nature-based methods to modify their homes and neighborhoods, making them safer without having to relocate. Others found that seasonal movement—traveling for part of the year to access water or markets and then returning home—became a stable, long-term strategy. In these instances, the projects didn't stop movement; they made a specific kind of movement sustainable. They allowed people to remain rooted in their culture and community while navigating a changing environment.
The study also highlighted the importance of knowledge and hope. Many participants reported that working on these projects increased their understanding of climate change and their ability to teach others. This "climate literacy" changed how they viewed their risks and their future. Even when the economic benefits were slow to arrive, the sense of agency and the belief that they could shape their own destiny kept them engaged. In some difficult cases, however, the projects were not enough to overcome deep-seated poverty or severe environmental damage. Here, the research showed that nature-based solutions could not magically fix every problem, and sometimes the desire to move remained, driven by forces larger than the local project could handle.
The data from these sixty stories painted a clear picture: the decision to move or stay is rarely about a single factor like a flood or a drought. It is about how a person interprets their situation. The researchers found that nature-based solutions influenced this interpretation by strengthening social networks, improving mental well-being, and creating a sense of stewardship over the land. When people felt they had a role in protecting their environment, they often felt more capable of managing their lives, whether that meant staying put or moving on.
Crucially, the study suggests that we should stop judging the success of these projects by whether people leave or stay. A project is not a failure just because someone moves away, nor is it a success just because someone stays. The true measure is whether the project expanded the person's ability to make a choice that leads to a better life. If a nature-based solution gives a family the tools to survive a drought in their village, that is a success. If it gives a young person the skills and confidence to move to a city and find work, that is also a success. The goal is not to freeze populations in place or to push them out, but to ensure they have the freedom and capacity to navigate a changing world.
This approach offers a new way to think about climate adaptation. It moves away from the idea of a single, correct answer and embraces the complexity of human experience. By focusing on the stories of real people, the research shows that nature-based solutions are most powerful when they are integrated into the daily lives and aspirations of communities. They work best when they are not just about planting trees or building barriers, but about building the capacity of people to decide their own futures. In a world where the climate is changing faster than ever, the ability to choose how to live, where to live, and how to adapt is perhaps the most valuable resource of all.
