International agreements aim to conserve 17% of Earth's land area by 2020 but include no area‐based conservation targets within the working landscapes that support human needs through farming, ranching, and forestry. Through a review of country‐level legislation, we found that just 38% of countries have minimum area requirements for conserving native habitats within working landscapes. We argue for increasing native habitats to at least 20% of working landscape area where it is below this minimum. Such target has benefits for food security, nature's contributions to people, and the connectivity and effectiveness of protected area networks in biomes in which protected areas are underrepresented. We also argue for maintaining native habitat at higher levels where it currently exceeds the 20% minimum, and performed a literature review that shows that even more than 50% native habitat restoration is needed in particular landscapes. The post‐2020 Global Biodiversity Framework is an opportune moment to include a minimum habitat restoration target for working landscapes that contributes to, but does not compete with, initiatives for expanding protected areas, the UN Decade on Ecosystem Restoration (2021–2030) and the UN Sustainable Development Goals.

工作景观至少需要20％的原生栖息地

国际协议旨在到2020年保护地球上17％的土地，但在工作景观中不包括基于区域的保护目标，这些目标通过农业，牧场和林业来满足人类的需求。通过对国家/地区立法的审查，我们发现只有38％的国家/地区在保护工作景观内的自然栖息地方面具有最低面积要求。我们主张将本地栖息地增加到至少低于此最低要求的工作景观面积的20％。该目标有利于粮食安全，自然界对人类的贡献以及保护区代表不足的生物群落中保护区网络的连通性和有效性。我们还主张将本地栖息地维持在更高水平，目前已超过最低要求20％，并进行了文献综述，结果表明在特定景观中甚至需要超过50％的原生栖息地恢复。2020年后的全球生物多样性框架是一个时机合适的时机，其中应包括工作景观的最低栖息地恢复目标，这有助于但不与扩大保护区的举措，联合国生态系统恢复十年（2021-2030年）和联合国可持续发展目标。
