This paper investigates the documentation produced by 21 Horizon 2020 (H2020) projects for the use of Nature Based Solutions (NBS) for climate change adaptation (NBaS). Accordingly, an updated state-of-the-art on current knowledge and its limits is presented. Findings are then capitalized on for highlighting research needs. The main objective of this study is to inform future orientations on NBaS research. Accordingly, it can be considered as an effort to complement the 2021 European strategy for climate change adaptation, under which NBaS is listed as one of the three cross-cutting priorities. The obtained results reflect actual outcomes from completed projects, while ongoing projects provided a substantial amount of relevant knowledge. From the exhaustive knowledge-research need inventory, one of the most significant identified gaps was the need for developing further the fundamental scientific basis behind these solutions, as the concept favors its practical nature and places less emphasis on its scientific counterpart.

本文调查了 21 个 Horizo​​n 2020 (H2020) 项目为使用基于自然的解决方案 (NBS) 适应气候变化 (NBaS) 生成的文档。因此，提出了有关当前知识及其局限性的最新最新技术。然后利用调查结果突出研究需求。本研究的主要目的是为未来的 NBAS 研究方向提供信息。因此，它可以被视为对 2021 年欧洲气候变化适应战略的补充，根据该战略，NBaS 被列为三个跨领域优先事项之一。获得的结果反映了已完成项目的实际结果，而正在进行的项目提供了大量的相关知识。从详尽的知识研究需求清单中，
