A Recent and Systematic Review on Water Extraction from the Atmosphere for Arid Zones

Round 1

Reviewer 1 Report

Dear Authors, thank you for the interesting and useful study.

The structure of the article is well verified, contains the sections necessary for the review manuscript, although the section “Results and Discussion” is absent. The introduction is written rather succinctly, little attention is paid to the relevance of research. The list of used literature contains 68 sources, only 23 of which - over the past 5 years. Some figures require quality improvement.

Below are the main comments to the manuscript, the remaining technical comments are given in the text of the Reviewer’s PDF.

1. Comparison of the economic effects of the technologies under consideration is not provided.
2. There is no comparison of the productivity of the technologies under consideration. A detailed comparison of productivity (l / m2 / day or kg / m2 / day) should be given in the Results and Discussion section.
3. There is a very lack of specifics (an example of the application of technology with an indication of the country and city).
4. Table 1 contains a comparison of all considered methods? If so, why is it listed in the “Desiccant Systems” section? I recommend that you pay attention to its detailed consideration in the "Results and Discussion" section.
5. I recommend adding a section "Acknowledgments".
6. The "Conclusions" section should be expanded. I recommend adding to it a comparison of specific indicators of all the technologies considered.

Reviewer 2 Report

The topic is interesting from the point of view of topic concentrated on water extraction from the atmospheric air. There are lack of articles on this topic, therefore information with reference to presented examples on this subject is valuable.

The study has good potential and the manuscript is well written.

Despite this, I have 2 comments regarding redrafting of the manuscript:

1. The introduction lacks information about the novelity and the global significance of the presented research results. I mean, how other authors could benefit from the solutions presented by you.
2. It is necessary to refer to a broader approach to the subject by comparing it to similar research from a global perspective. It is necessary to cite current articles of world famous authors who research this topic.

Reviewer 3 Report

This paper provides a comprehensive review on the extraction of water from atmosphere in arid zones. This paper is valuable and well written and organized.

This paper could be made more valuable by adding a section with name “insights for “policymakers and practitioners”. Please add a section before conclusion. This section should include detailed opinions and recommendations written by authors based on strong evidence.
