摘要

本研究应用差异（DID）估计程序，量化了2016年孟加拉国爆发的影响超过15000公顷的疾病后，稻瘟病（稻瘟病致病型小麦）导致的小麦产量、小麦销售、消费或储存量以及小麦籽粒价值的损失。据估计，受爆炸影响地区的家庭因爆炸造成的产量损失平均为540 kg ha−1。2016年疫情期间，估计小麦总产量损失约为8205吨，价值210万美元。基于这些见解，我们讨论了在控制小麦瘟病等跨界疾病方面进行长期有保证的投资和协调一致的研究工作的必要性，包括天气预报驱动的预警系统和传播抗药性品种的重要性。

Quantifying Wheat Blast Disease Induced Yield and Production Losses of Wheat: A Quasi-Natural Experiment

Applying the difference-in-difference (DID) estimation procedure, this study quantifies the wheat blast (Magnaporthe oryzae pathotype Triticum) induced losses in wheat yield, quantity of wheat sold, consumed, or stored, as well as wheat grain value in Bangladesh in 2016 following a disease outbreak that affected over 15,000 ha. Estimates show that the blast-induced yield loss was 540 kg ha−1 on average for households in blast-affected districts. Estimated total wheat production loss was approximately 8,205 tons worth USD 2.1 million in during the 2016 outbreak. Based on these insights, we discuss the need for long-term assured investment and concerted research efforts in controlling transboundary diseases such as wheat blast, including the importance of weather forecast driven early warning systems and the dissemination of blast-resistant varieties.
