Agricultural pest management faces mounting challenges with increasing pressure to reduce chemical pesticide use while ensuring food security, and environmental sustainability. Ecologically centered approaches, such as integrated pest management (IPM), offer promising sustainable agroecological crop protection alternative solutions to pesticides. This study assesses the investment viability and environmental sustainability of two IPM interventions-mango fruit fly IPM (FF-IPM) and push-pull technology (PPT) in Kenya and Uganda, using project investment and adoption data from 2007 to 2021. The study also evaluates these technologies contribution to food security and poverty reduction. FF-IPM integrates biological control, cultural practices, and targeted bait traps to manage fruit flies in mango production, while PPT employs Desmodium and Brachiaria grass to control pests and striga weed. The findings highlight that these IPM interventions achieved a combined net present value of $500 million, with a benefit-cost ratio of about 8:1, and an internal rate of return of 21%, comparable to returns from improved crop varieties. These technologies also improved food security for 641,000 people, lifted 445,349 people above the poverty line, representing 2% of the poor population in both countries, and generated an average income increase of $5 per capita in Kenya and Uganda annually. Environmentally, they sequestered 2.7 million tons of CO equivalent, valued at $12.2 million, and reduced pesticide use by more than 526,000 L between 2007 and 2021. These results demonstrate the potential of IPM approaches to simultaneously enhance livelihoods, local economies, and generate global environmental public goods, suggesting that addressing adoption barriers could further amplify these positive outcomes.
农业害虫管理面临着越来越大的挑战，需要在确保粮食安全和环境可持续性的同时，减少化学农药的使用。以生态为中心的方法，如综合虫害管理（IPM），为减少农药使用提供了有前途的可持续农业生态作物保护替代方案。本研究评估了 2007 年至 2021 年期间在肯尼亚和乌干达实施的两种 IPM 干预措施（芒果果实蝇 IPM（FF-IPM）和推拉技术（PPT）的投资可行性和环境可持续性，并利用项目投资和采用数据进行了评估。该研究还评估了这些技术对粮食安全和减贫的贡献。FF-IPM 整合了生物防治、文化实践和有针对性的诱饵陷阱，以管理芒果生产中的果实蝇，而 PPT 则利用德斯莫德草和臂形草来控制害虫和 Striga 杂草。研究结果表明，这些 IPM 干预措施实现了 5 亿美元的净现值，效益成本比约为 8:1，内部收益率为 21%，与改良作物品种的回报率相当。这些技术还提高了 641,000 人的粮食安全，使 445,349 人摆脱贫困，占两国贫困人口的 2%，并使肯尼亚和乌干达每年的人均收入平均增加 5 美元。在环境方面，它们封存了 270 万吨二氧化碳当量，价值 1220 万美元，并在 2007 年至 2021 年期间减少了超过 526,000 升的农药使用。这些结果表明，IPM 方法有可能同时提高生计、地方经济，并产生全球环境公益，表明解决采用障碍可能会进一步放大这些积极成果。
