摘要

可持续捕获野生动物是粮食安全和保护的一个主要问题。在非洲,捕获野生动物主要是为了维持生计,这仍然是一个挑战。在这项研究中,我们以水鸟为自然资源模型,通过菲特里湖(乍得)的副渔获物评估了捕捞的可持续性。我们通过连续四年(2018-2021 年)的空中距离采样估算了 24 个目标分类群的丰度,同时通过采访约 5500 名渔民中的 105 个样本估算了捕获鸟类的数量。通过对其潜在的过度增长进行建模,我们发现包括濒临灭绝的黑冠鹤 Balearica pavonina 在内的四个物种存在过度开发的高风险,这可能是由于逃离博科圣地安全危机的渔民大量涌入菲特里湖所致。综述与应用:这项工作很可能是对非洲鸟类收获可持续性的首次定量研究。它有助于填补《非洲-欧亚水鸟协定》和《拉姆萨尔公约》等多个多边环境协定战略规划中的方法和信息空白。特别是,这项工作有助于在拉姆萨尔遗址管理计划中实施自然资源(包括鸟类)的适应性管理。菲特里湖等非洲湿地在中期内可能无法为武装冲突迫使流离失所的平民进入这些生物多样性据点提供足够的自然资源。
