Upstream innovation leakage in Uganda’s coffee planting material pipeline
研究了乌干达罗布斯塔咖啡种植材料供应链中，上游创新如何因苗圃生产实践不佳而未能有效传递给下游小农，导致低产和病害问题，对农业政策制定者具有参考价值。
Abstract Policies and institutions shape the incentives that influence innovation, technology adoption and productivity. We characterise the robusta coffee planting material pipeline in Uganda that connects upstream innovation in improved germplasm to downstream coffee producers. A nationally representative survey of coffee nursery operators reveals poor and heterogeneous production practices, potentially reflecting shifting policy priorities. The majority of smallholder coffee farmers consequently get inferior, disease-prone seedlings—thereby locking in decades of continued low productivity. Given Uganda’s ambition to drastically increase coffee production, detecting, understanding and addressing these problems should be a top priority as a prerequisite to effective agricultural policy and enhanced productivity.
