Dear Laddaporn Ruangpan and co-authors,

Thank you for the submission of your manuscript “Nature-Based Solutions for hydro-meteorological risk reduction: A state-of-the-art review of the research area”.
As you know, two reviewers have now provided detailed reviews, which you have replied in detail to. Both reviewers recommended major revisions and highlighted serval major issues regarding the design of your research, the chosen methods and evaluation criteria as well as the added-value for the scientific community. In particular, in addition to mentioned issues by the reviewers, I kindly ask you to include in your manuscript more explicit also the terms of hazards and risks because the different communities addressing NBS also define differently the following terms related their research field:
• hydro-meteorological hazard vs hydro-meteorological risk vs hydro-meteorological disaster: It seems throughout the manuscript that you use hazard and risk synonymously (e.g. p5 l10). Furthermore, which hazards types did you include/select in your review considering the brought spectrum of hydro-meteorological hazards (e.g. storms, hail, snow avalanches, flash floods, …). Please provide here further explanations.
• vulnerability
• climate change adaptation
• disaster risk reduction
Moreover, I wonder why you did not include the term ‘risk’ in your second order concept for the literature research even ‘risk reduction’ is mentioned in the title of your manuscript.

I would like to invite you to submit a revised version of your manuscript addressing all these issues. Would you please also provide an ‘author’s reply’ to the reviewers (feel free to use the same words that you used in what you have already uploaded) and include, in the same author reply document, a track changes document between the old manuscript and the new one. Please be aware that the decision ‘major revision’ of this manuscript version does not guarantee it will be accepted in NHESS.
I look forward to seeing the next version of your manuscript and will send it out again to the previous reviewers.

Dear Laddaporn Ruangpan and co-authors,
I received now the two review reports of your re-vised manuscript “Nature-Based Solutions for hydro-meteorological risk reduction: A state-of-the-art review of the research area”.
One reviewer had not further suggestions and the second one addressed several missing papers which should be considered in the review. The main issue are:
• Please consider if it is possible to extend your literature search also for the last months and integrated the newest publication if there are only few publications.
• However, I checked the mentioned special issue (the last mentioned editorial paper) and identified that all papers of the special issue should appear in your search because they were published before December 2018, the journal is included in Scopus and they should meet your search criteria. Therefore, I kindly ask you to clarify this issue.
• Please also address the comment regarding the Sustainable Development Goals as you addressed this also in your introduction.
• Furthermore, I highly recommend to address in the discussion the pro and cons of your systematic search design because two reviewers comments on the drawbacks and missing crucial papers.
I have myself some more technical issues which should be addressed:
• Please find attached the pdf-file with several comments. Please check the format if it is only highlighted in yellow and no further comments are provided
• I kindly ask you (the second time) to apply the guidelines of NHESS for manuscript preparation (e.g. missing: author contribution, competing interests; physical dimensions and units (e.g. table 4 & 5), figure captions, …).
• In the track-change version I could not find the required changes of language editing as requested for the last version. Please provide here further information
I would like to invite you to submit a revised version of your manuscript addressing all these issues.
I look forward to seeing the next version of your manuscript which I will not send out for further review, but rather, will make the decision myself, assuming no major items come up in the revised manuscript for which I need outside reviewers to aid me in my decision.
