Exploring the nexus of climate change, energy use, and maize production in Benin: In-depth analysis of the adequacy and effectiveness of adaptation

To mitigate the impact of climate change, farmers are increasingly opting for more efficient energy allocation in agricultural production. This study aims to evaluate the effectiveness of these methods employed by maize growers in Benin, while identifying the constraints associated with their implementation. A survey was conducted among 230 maize growers in Benin to achieve the objectives of the study. The Data Envelopment Analysis method was utilized to measure farmers' technical efficiency, followed by the application of the Tobit model to identify the factors determining this efficiency. The comparative analysis of efficiency indices reveals that farmers who prioritize increased utilization of agricultural inputs exhibit higher levels of technical efficiency while maintaining constant yields. In terms of technical efficiency at varying yields, farmers who increase their labor input demonstrate the highest level of efficiency. Subsequently, farmers who choose to augment the quantities of agricultural inputs exhibit greater scale efficiency. The Tobit model reveals that age, experience, maize production area, utilization of insecticides and NPK fertilizers are significant determinants influencing the efficiency levels of maize growers. Maize growers encounter challenges in accessing improved maize seeds and agricultural machinery, as well as facing financial constraints.
