Do Farmers and the Environment Benefit from Adopting Integrated Pest Management Practices? Evidence from Kenya
利用肯尼亚芒果种植户数据，估计采用综合虫害管理措施对产量、收入、农药使用及环境健康的影响，发现采用者收益更高且损害更小。
Abstract We estimate the impacts of a bundle of integrated pest management (IPM) practices on mango yield, mango net income, insecticide use, human health and the environment, using recent household survey data of mango growers in Kenya. We employ a multinomial endogenous switching treatment regression model with an ordered probit selection rule to establish counterfactual outcomes. Our results indicate that IPM‐adopting farmers have higher mango yields and mango net income, and also use lower quantities of insecticide and cause less damage to the environment and to human health. In addition, switching from one IPM to multiple IPM practices generates greater economic, environmental and human health benefits. These results suggest intensification of IPM‐adoption efforts and encouragement of the use of multiple IPM practices. These positive outcomes could be achieved through greater provision of technical support and extension services to farmers.
