SignificanceUnderstanding the impacts of urbanization and the associated urban land expansion on species is vital for informed urban planning that minimizes biodiversity loss. Predicting habitat that will be lost to urban land expansion for over 30,000 species under three different future scenarios, we find that up to 855 species are directly threatened due to unmitigated urbanization. Our projections pinpoint rapidly urbanizing regions of sub-Saharan Africa, South America, Mesoamerica, and Southeast Asia where, without careful planning, urbanization is expected to cause particularly large biodiversity loss. Our findings highlight the urgent need for an increased focus on urban land in global conservation strategies and identify high-priority areas for this engagement.
意义
了解城市化及其相关的城市土地扩张对物种的影响，对于实现最小化生物多样性损失的明智城市规划至关重要。通过预测在三种不同未来情景下，超过 30000 个物种将因城市土地扩张而丧失的栖息地，我们发现高达 855 个物种因未得到缓解的城市化而直接受到威胁。我们的预测指出了撒哈拉以南非洲、南美洲、中美洲和东南亚这些城市化迅速发展的地区，在这些地区，如果没有谨慎的规划，城市化预计将导致特别大的生物多样性丧失。我们的研究结果强调了在全球保护战略中更加关注城市土地的迫切需要，并确定了需要优先关注的领域。
