Special Issue Information
Dear Colleagues,
Atmospheric water harvesting (AWH) has emerged as a promising solution to address global water scarcity, particularly in arid and remote regions where conventional water resources are limited. With increasing population growth, climate change, and rising water demand, alternative and sustainable water generation technologies are becoming critically important. The atmosphere contains a significant amount of water vapor, which can be converted into liquid water through a variety of physical and chemical processes. Recent advances in materials science, thermodynamics, and energy systems have accelerated the development of efficient atmospheric water harvesting technologies.
This Special Issue focuses on recent progress in atmospheric water harvesting technologies, including both passive and active systems. Key approaches include fog and dew harvesting, adsorption- and desiccant-based systems, vapor compression refrigeration cycles, thermoelectric cooling technologies, membrane-based systems, and other innovative AWH technologies. In addition, emerging materials such as metal–organic frameworks (MOFs), hydrogels, hygroscopic salts, and nanostructured sorbents have demonstrated significant potential for improving water capture performance, especially under low relative humidity conditions.
The Special Issue aims to provide a comprehensive platform for researchers to present advances in materials design, system integration, thermodynamic modeling, and renewable-energy-driven AWH systems. Contributions addressing device optimization, energy efficiency, climate adaptability, and real-world applications are particularly encouraged. By bringing together interdisciplinary research in materials science, environmental engineering, and energy systems, this Special Issue seeks to highlight innovative solutions that can enhance the feasibility and scalability of atmospheric water harvesting as a sustainable water supply technology.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
