Migrants' Remittances and Climate Change Adaptation among Maize and Cassava Producers in Rural Togo
Using data from 5,806 rural producers in Togo, this study employs an endogenous switching probit model to demonstrate that migrants' remittances significantly enhance climate change adaptation and agricultural productivity, particularly for maize farmers, thereby underscoring the need for policies that facilitate remittance access to bolster rural food security.

In the rural landscapes of West Africa, where the rhythm of life is dictated by the seasons and the soil, farmers face a growing uncertainty. The climate is shifting, bringing hotter days and more erratic rains that threaten the harvests of staple crops like maize and cassava. When a family's livelihood depends on the weather, a single bad season can mean hunger. For decades, economists have understood that when people move away from their villages to find work, they often send money back home. These transfers, known as remittances, are not just extra cash; they are a lifeline that allows families to smooth out the bumps in their financial road. The central question for researchers has long been whether this money does more than just buy food today. Can it also help a family prepare for tomorrow? Specifically, does having access to money from a relative abroad give a farmer the confidence and the means to change how they farm, to adopt new seeds or techniques that can survive a drought or a flood?
This question drove a team of researchers to look closely at the lives of thousands of farming households in Togo. They wanted to see if the money sent by migrants was actually changing the way farmers responded to a warming world. To do this, they gathered detailed information from a massive survey of nearly 5,800 families who grow maize and cassava, the two most important food crops in the country. They combined this with local weather data to see exactly what conditions these farmers were facing. The researchers were careful to account for the fact that families who receive money might already be different from those who do not—perhaps they are more educated or live in different areas. By using a statistical approach that compares what actually happened with what would have happened if the situation were different, they could isolate the true effect of the money itself.
The study focused on two distinct types of farmers: those who grow maize, a cereal that is sensitive to heat and water, and those who grow cassava, a root crop known for its ability to withstand harsh conditions. The researchers found that receiving money from a migrant relative significantly increased the likelihood that a farmer would take steps to adapt to climate change. However, the strength of this effect depended entirely on what the farmer was growing. For maize producers, the impact was dramatic. The data showed that when these farmers received remittances, their probability of adopting adaptation strategies jumped by more than 83 percentage points. In simpler terms, the money acted as a powerful catalyst, allowing maize farmers to invest in the changes they needed to survive.
In contrast, the story for cassava farmers was much more muted. While remittances still had a positive influence, the boost to their adaptation efforts was far smaller, increasing their likelihood of acting by only about 27 percentage points. The researchers also discovered a surprising twist: for cassava farmers who did not receive money, the data suggested that if they had suddenly received it, their likelihood of adapting might have actually gone down. This counterintuitive finding hints that the relationship between money and adaptation is not a simple straight line; it depends heavily on the specific crop, the local soil, and the existing resources of the household. For cassava, which is naturally hardy, the pressure to change farming methods might be lower, or the money might be spent on other immediate needs rather than long-term agricultural adjustments. However, when looking at the overall population, the study confirms that remittances still contribute positively to the probability of adaptation among cassava producers, with an average increase of nearly 15 percentage points.
Beyond the crops, the study revealed the specific factors that help or hinder a farmer's ability to adapt. For maize growers, being part of a local agricultural cooperative made a significant difference, as did having a higher income and living in certain regions. The temperature also played a role; as average temperatures rose, maize farmers were more likely to take action, but only if they had the financial backing to do so. For cassava growers, the quality of the soil was a key driver. If the land was fertile, farmers were more inclined to adapt, regardless of whether they received money. The research also highlighted that the education level of the person sending the money mattered; migrants with more education tended to send funds that were more effectively used for adaptation, while those without formal education sent less.
The researchers concluded that while remittances are a vital tool for helping rural families cope with climate change, they are not a one-size-fits-all solution. The money works best for crops like maize, where the threat is immediate and the need for new technologies is high. For other crops, or in different contexts, the money might be used for different purposes, or the farmers might not feel the same urgency to change their methods. The study suggests that policymakers should not just view remittances as a private family matter but as a public resource that can be leveraged to improve food security. By creating systems that make it easier for rural families to access and use these funds, governments could help farmers build resilience against a changing climate. The findings paint a clear picture: money from abroad can be a shield against the storm, but the strength of that shield depends on the ground it is built upon.
