Extreme weather events have severe impacts on food systems, especially for smallholders in global food value chains (GFVCs). There is an urgent need to understand (a) how climate shocks manifest in food systems, and (b) what strategies can enhance food system resilience. Integrating satellite, household and trade data, we investigate the cascading impacts after two consecutive hurricanes on smallholder banana farmers in Dominican Republic, and determinants of their recovery. We found that farmers experienced an 'all-or-nothing' pattern of damage, where 75% of flooded farmers lost > 90% of production. Recovery of regional production indicators took ca. 450 days. However, farm-level recovery times were highly variable, with both topographic and human capital factors determining recovery. Utilising this case study, we show that engaging in a GFVC impeded recovery via 'double exposure' of production loss and losing market access. Our results suggest that strategies to enhance resilience, with a particular focus on recovery, in GFVCs should promote trader loyalty, facilitate basin-scale collaboration and expand risk-targeted training.

极端天气事件对粮食系统有严重影响,尤其是对全球粮食价值链(GFVCs)中的小农户。迫切需要了解:(a)气候冲击在粮食系统中如何表现,以及(b)哪些策略可以增强粮食系统的复原力。整合卫星、家庭和贸易数据,我们调查了连续两次飓风对多米尼加共和国小农户香蕉种植户的连锁影响及其恢复的决定因素。我们发现,农民经历了一种“全有或全无”的损害模式,其中75%的受灾农民损失了超过90%的产量。区域生产指标的恢复大约需要450天。然而,农场层面的恢复时间差异很大,地形和人力资本因素都决定着恢复情况。利用这个案例研究,我们表明,参与全球粮食价值链会通过生产损失和失去市场准入的“双重暴露”阻碍恢复。我们的结果表明,增强全球粮食价值链复原力(尤其注重恢复)的策略应促进贸易商忠诚度、推动流域规模的合作并扩大针对风险的培训。
