Abstract [en]

This study examines the farm-level economic benefits and aggregate welfare impacts of adopting push–pull technology (PPT)—an innovative, integrated pest and soil-fertility management strategy—with a set of household- and plot-level data collected in western Kenya. The evaluation is based on a combination of econometric and economic surplus analysis. Treatment effect estimates are used to assess the technology-induced shift in the maize supply curve, which is then used as an input to the economic surplus analysis. Finally, the aggregate poverty impact is computed using the economic surplus estimates. We observe that the adoption of PPT led to significant increases in maize yield and net maize income. The technology has significant potential benefit in terms of increasing economic surplus and reducing the number of people considered poor in western Kenya. Important factors influencing the decision to adopt PPT included access to information, household education, social capital, and social networks. We conclude that effective policies and development programmes for promoting PPT in Kenya should include information delivery and education mechanisms that are more effective.
