Agricultural systems are increasingly threatened by the growing risks associated with climate change—notably environmental degradation, natural disasters and water depletion. Local and traditional farming communities are disproportionately vulnerable to these factors due to their reliance on agriculture for subsistence and livelihood. To mitigate the risks from these threats, local communities often depend on practices that have been passed down through generations to guide the food production process.

In Benin, a combination of technological advancements and population shifts from rural areas to urban areas have threatened the retention of these traditional practices and have also created space for new knowledge to be introduced. The intention of this study was to explore how different ethnic groups in Benin produce yam, and how environmental land factors in the Atacora region push yam farmers to migrate to other areas. Areas included in this study with more fertile land and experiencing influx of migrants from Boukoumbé in the Atacora region were Tchaourou and Bemberké  (in the Department of Borgou) and Glazoué and Savé (in the Department Collines).  The research question was: How social networks and internal migration can shape farmers’ knowledge of yam production and how is knowledge transmitted from one generation to the next and between social groups?

Internal migration is a common practice for many ethnic groups living in Sudano-Guinean zone ( and the Sudanian zone). These regular movements indicate that there are constant communication flows between these regions. Each ethnic group may carry their own local knowledge, traditional uses and conservation practices related to natural resources, and is also exposed to new ideas as migration and settlements take place. Social networks and social capital are important aspects when considering internal migration patterns; often migrant villages are dominated by intermediate and extended family members living in different households. Further, having a relative or an acquaintance is often a prerequisite for farmers establishing themselves in a migrant village.

We found that the differences in planting practices such as varieties selected, planting season, and conservation techniques used by the different ethnic groups surveyed were not significant, and more based on phyto-geographical factors and availability of land. Knowledge of yam production was often passed down within the family, with 1-5 scale, a score of 4.87 reported. Only 7 % of farmers interviewed participated in trainings, extension agents, organized cooperatives, radio emissions, etc., as the focus areas of these interventions are concentrated on cash crops such as cotton and rice.

87 percent of migrants stated that « manque de terre » and « la terre est fatigué »  (literal translation is lack of arable land, and land is worn down) were the primary reasons they left the Atacora region, indicating that environmental degradation was a driving cause for many. When arriving to their new home, in order to attain land, farmers would often work on the land of a permanent settler in exchange for having a small area for self-cultivation, negotiate with the king, rent and pay with a portion of harvest or money, or sometimes it was gifted. In some regions such as Tchaourou, access to land was easier to attain than others.

Climate change is predicated to exacerbate the rate and frequency of migration around the world. There is still much to explore in terms of this rural-rural migration pattern happening between the north and central regions of Benin. Efforts to document  how these movements impact blending of cultures and languages as different ethnic groups, once separated by distance, find themselves living in the same areas are critical to understanding these changing dynamics. Further, these studies can have important implications for understanding land-use change, as yam production that was typically spread out in multiple areas may become more concentrated in specific zones.
