Abstract Achieving land degradation neutrality (LDN) was adopted by countries in 2015 as one of the targets of the global Sustainable Development Goals (SDGs). As LDN is a relatively new concept there is an increasing need for evidence on the potential socio-economic and environmental benefits of LDN as well as how an enabling environment for implementing LDN measures can be developed. This paper summarises the results from a global survey of LDN stakeholders, and a review of national progress in target setting that was commissioned by the United Nations Convention to Combat Desertification (UNCCD) in 2018. The study presents the perceptions of relevant stakeholders on the key components of an enabling environment for achieving and maintaining LDN (institutional, financial, policy/regulatory, and science-policy) as well as expectations of multiple benefits from its implementation. We also highlight key challenges and gaps in progress to date that are emerging from ongoing national target setting programs to implement LDN. The study finds that progress in implementing LDN has been widespread across countries. However there remains a lack of awareness of LDN and its key concepts along with high-level political buy-in. This may be impeding the integration of LDN into national development planning and budgeting processes where progress was assessed as limited. National capacities for securing land tenure and governance arrangements and integrated land use planning were perceived as comparatively low, further hampering the implementation of LDN. Despite these gaps, most stakeholders (>90 %) who participated in the global survey expected LDN to deliver a broad range of multiple benefits for human wellbeing, livelihoods and the natural environment. We argue that greater efforts are needed to raise awareness of LDN, educate core stakeholders in its concepts, enablers and benefits, raise its political profile, and provide evidence on national measures that will support implementation of LDN.

为土地退化零增长提供有利环境和多重效益：利益相关者的看法和进展

摘要 实现土地退化零增长 (LDN) 于 2015 年被各国采纳为全球可持续发展目标 (SDG) 的具体目标之一。由于 LDN 是一个相对较新的概念，因此越来越需要关于 LDN 潜在社会经济和环境效益的证据，以及如何开发实施 LDN 措施的有利环境。本文总结了对 LDN 利益相关者进行的全球调查的结果，以及对 2018 年联合国防治荒漠化公约 (UNCCD) 委托进行的国家目标设定进展的审查。该研究介绍了相关利益相关者对关键问题的看法实现和维护 LDN 的有利环境的组成部分（制度、金融、政策/监管、和科学政策）以及对其实施的多重好处的期望。我们还强调了目前正在进行的国家目标设定计划中出现的主要挑战和进展中的差距，以实施 LDN。该研究发现，在实施 LDN 方面取得了广泛的进展。然而，仍然缺乏对 LDN 及其关键概念以及高层政治支持的认识。这可能会阻碍将 LDN 纳入国家发展规划和预算编制过程，因为进展被评估为有限。人们认为确保土地保有权和治理安排以及综合土地使用规划的国家能力相对较低，进一步阻碍了 LDN 的实施。尽管存在这些差距，大多数利益相关者 (> 90 %) 参与全球调查的人期望 LDN 为人类福祉、生计和自然环境带来广泛的多重效益。我们认为需要做出更大的努力来提高对 LDN 的认识，教育核心利益相关者了解其概念、推动因素和好处，提高其政治形象，并提供有关支持 LDN 实施的国家措施的证据。
