Using synthetic pesticides to manage pests can threaten pollination services, affecting the productivity of pollination-dependent crops such as avocado. The need to mitigate this negative externality has led to the emergence of the concept of integrated pest and pollinator management (IPPM) to achieve both pest and pollinator management, leading to complementary or synergistic benefits for yield and quality of the harvest. This paper aims to evaluate the potential economic and welfare impact of IPPM in avocado production systems in Kenya and Tanzania. We utilize both primary and secondary data and employed the economic surplus model. On average the potential economic gain from the adoption of IPPM is US$ 66 million annually in Kenya, with a benefit-cost ratio (BCR) of 13:1, while in Tanzania US$ 1.4 million per year, with a BCR of 34:1. The potential benefits from IPPM intervention gains are expected to reduce the number of poor people in Kenya and Tanzania by 10,464 and 1,255 people per year respectively. The findings conclude that policies that enhance the adoption of IPPM can fast-track economic development and therefore improve the livelihoods of various actors across the avocado value chain.
使用合成农药来管理害虫可能会威胁授粉服务,从而影响到依赖授粉的作物(如鳄梨)的生产力。为了减轻这种负面的外部性,人们提出了综合病虫害和传粉媒介管理(IPPM)的概念,以实现病虫害和传粉媒介的管理,从而为产量和收获质量带来互补或协同的效益。本文旨在评估肯尼亚和坦桑尼亚鳄梨生产系统中采用 IPPM 的潜在经济和福利影响。我们利用了原始数据和二手数据,并采用了经济盈余模型。平均而言,在肯尼亚,采用 IPPM 的潜在经济效益为每年 6600 万美元,效益成本比(BCR)为 13:1,而在坦桑尼亚,每年为 140 万美元,BCR 为 34:1。预计 IPPM 干预措施的潜在收益将使肯尼亚和坦桑尼亚每年分别减少 10464 人和 1255 名贫困人口。研究结果得出结论,加强采用 IPPM 的政策可以加速经济发展,从而改善鳄梨价值链各环节参与者的生计。
