Economic impacts of adoption of fall armyworm management practices on household welfare of smallholder maize farmers in Ghana

This study analyzed the factors influencing adoption of fall armyworm management practices (FAW MPs) and the impacts of the adoption of these management practices on maize yield and household maize income. The findings show that relative to non-adoption, the joint adoption of a combination of early planting and pesticide application had greater impacts on both maize yield and household maize income. Our findings indicate that efforts should be geared towards training farmers to practice different combination of the FAW MPs in controlling fall armyworm on their farms while improving their access to support services such as extension and input supply. The dataset is a primary data with most of the variables coded in the binary form and some as dummy variables. The data can be analyzed and interpreted using the multinomial endogenous switching regression model in STATA through the usage of the selmlog command.

本研究分析了草地贪夜蛾防控措施（fall armyworm management practices，FAW MPs）的采纳影响因素，以及此类防控措施的采纳对玉米产量与农户家庭玉米收入的影响。研究结果显示，相较于未采纳防控措施的情况，同时采用早播与农药施用组合策略的农户，其玉米产量与家庭玉米收入的提升效果更为显著。本研究结果表明，相关工作应着力于培训农户掌握多种草地贪夜蛾防控措施的组合应用方法，以在其农田中有效防控草地贪夜蛾，同时改善农户在技术推广与农资供应等支持服务方面的获取渠道。本数据集为一手调研数据，多数变量采用二分类编码形式，部分变量为虚拟变量。可借助STATA软件中的selmlog命令，运用多项内生转换回归模型对该数据进行分析与解读。
