There is limited quantitative evidence of the effects of socio-economic shocks on biological resource use. Focusing on wild meat hunting, a substantial livelihood and food source in tropical regions, we evaluated the impacts of the shock from Nigeria's coronavirus disease (COVID-19) lockdown on species exploitation around a global biodiversity hotspot. Using a 3-year quantitative dataset collected during and after the lockdown (covering 1008 hunter-months) and matching by time of year, we found that successful hunting trip rates were more frequent during the lockdown, with a corresponding increase in the monthly number, mass, and value of animals caught. Moreover, hunters consumed a larger proportion of wild meat and sold less during lockdown, compared to non-lockdown periods. These results suggest that local communities relied on wild meat to supplement reduced food and income during the lockdown, buffering the COVID-19's socio-economic shock. Our findings also indicate that wild species may be especially vulnerable to increased hunting pressure during socio-economic shocks.

COVID-19 社会经济冲击期间农村社区狩猎和利用野生动物肉的变化


关于社会经济冲击对生物资源利用的影响，定量证据有限。我们专注于野生动物肉狩猎，这是热带地区的重要生计和食物来源，我们评估了尼日利亚冠状病毒病 （COVID-19） 封锁的冲击对全球生物多样性热点周围物种开发的影响。使用在锁定期间和之后（涵盖 1008 个猎人月）收集的 3 年定量数据集并按一年中的时间进行匹配，我们发现在锁定期间，成功的狩猎旅行率更加频繁，每月捕获的动物数量、质量和价值也相应增加。此外，与非封锁时期相比，猎人在封锁期间消费的野生动物肉比例更高，销量也更少。这些结果表明，当地社区在封锁期间依靠野生动物肉来补充减少的食物和收入，从而缓冲了 COVID-19 的社会经济冲击。我们的研究结果还表明，在社会经济冲击期间，野生物种可能特别容易受到增加的狩猎压力的影响。
