Globally, food crops production has been challenged by the impacts of climate change. Climate change scholars have argued that rural dwellers, particularly smallholder farmers who engage in food crops production, suffer the most due to their low capacity to adapt. A growing body of knowledge also suggests that local practices serve as safeguards, that enable smallholder farmers to lessen their vulnerability in food crops productions. However, limited scholarly insight has been advanced about sustainable food production via the use of local practices. Through the mixed research approach, our study contributes to local practices and climate adaptation debates by examining the various local practices of smallholder farmers, the challenges they encounter with the use of such practices and the possibility for sustainable food crops production in the future. Our findings suggest that smallholders encounter multiple drawbacks in attempts to utilize local practices to adapt food crops production to climate change including the advent of modern farming inputs/practices. Even when multiple local practices (the planting of crops varieties, switching between crops and livestock rearing, reducing cultivatable land size) are utilized, only the increment in farm size, the use of income/remittances of rural-urban migrants to support food crops production, and early cultivation offered some possibilities of sustaining improvement in food crops production for the future. Therefore, we conclude that local practices are not necessarily panaceas for sustaining food crops production under climate change. We recommend further studies to pay attention to the sustainability of local practices under climate change.
