南部非洲的秃鹫每年提供1.8B美元的生态系统效益,但面临严重的人口减少。 Vultures in southern Africa offer $1.8B in annual ecosystem benefits, but face severe population declines.

鸟类生命国际的一份报告估计,南部非洲的秃鹫每年提供18亿美元的生态系统服务,包括卫生和虫害防治。 A report by BirdLife International estimates vultures in southern Africa provide $1.8 billion in annual ecosystem services, including sanitation and pest control. 这项研究的重点是博茨瓦纳、津巴布韦和赞比亚,注意到过去五十年,由于中毒和电击,秃鹫人口减少了80%至97%。 The study focuses on Botswana, Zimbabwe, and Zambia, noting vulture populations have fallen 80-97% in the last five decades due to poisoning and electrocution. 如果没有保护,年度经济损失可能达到4 700万美元,而养护努力每年可产生3 000万美元。 Without protection, annual economic losses could reach $47 million, while conservation efforts could generate $30 million annually.
