Ecohydrological Processes, Environmental Effects, and Integrated Regulation of Wetland Ecosystems, 3rd Edition

Dear Colleagues,

We are grateful to all authors, reviewers, and readers for their responses to the first and second editions of this Special Issue, entitled "Ecohydrological Processes, Environmental Effects, and Integrated Regulation of Wetland Ecosystems". You can access these articles for free via the following link:

Now, we plan to move forward with this topic, to which you are very welcome to contribute to.

Wetlands are among the most important ecosystems on Earth and play important multi-ecological service functions such as providing productivity, regulating climate, purifying water quality, sequestrating carbon, and controlling floods. Wetlands serve as sources, sinks, and transformers of a multitude of chemical, biological, and genetic materials. The conversion of sources and sinks of chemical materials highly depends on ecohydrological processes and microbial degradation. Wetland loss and degradation have occurred on a global scale due to intense human activities, and approximately 50% of wetlands has been lost over the past century. Intense anthropogenic disturbances have greatly degraded wetland functions by draining, dredging, and filling wetlands, modifying the hydrological regime, constructing artificial facilities, and polluting wetland habitats. Wetland habitats have been greatly threatened by the abovementioned human pressures and climate change, which can not only affect primary and secondary productivity, community composition and distribution, and biodiversity but also impact natural ecohydrological and biogeochemical processes. Meanwhile, the ecosystem services of wetlands have also been degraded due to changing wetland hydrology. Therefore, many protection and restoration projects have been conducted to restore degraded habitats, improve water quality, and control flooding. Wetland restoration is driven by policies such as the Ramsar convention on wetlands of international importance, the Clean Water Act of the US, the Water Framework Directive of the European Union, and others. Hopefully, increasing practices of protection and restoration will develop into an intentional activity that initiates or accelerates the recovery of degraded or destroyed wetlands in more countries.

We invite you to contribute your recent research in relation to understanding ecohydrological processes, environmental effects, and integrated regulation in wetland ecosystems to wetland conservation and management. The potential topics for focus in this Special Issue include, but not limited to, the following:

1. Hydrological processes in wetlands;
2. Wetland biogeochemistrical processes;
3. Wetland ecological risks;
4. Wetland structures and functions;
5. Environmental pollution in wetlands;
6. Ecohydrological processes in wetlands;
7. Wetlands conservation and restoration;
8. Effects of climate change on wetlands;
9. Ecological service functions in wetlands;
10. Ecological network analysis of wetlands.

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.
