Dear Colleagues,

Increasing world population is one of the major causes of environmental degradation and water security. Water security issues have been more salient in this century (e.g., water rights, water supply and storage safety, adequacy of quantity and quality of water, effective water use and irrigation, etc.). One needs to know the current status of water resources and the challenges of water security before developing creative and effective solutions to meet current and future water resource challenges.

Protecting the water and wastewater treatment infrastructure is key to maintaining the public health and environmental benefits of safe and clean water. For example, an effective system that can detect and respond, in a timely manner, to drinking water contamination threats needs to be designed. The coordination of the water sector with emergency services sector and an information tool that contains a comprehensive database and analytical methods for dealing with water contaminants are also important for preparedness, response, remediation, and recovery for water contamination events.

In the past few decades, significant changes in precipitation patterns and distribution (caused by climate change) have been identified. These affect the availability of water and increase the frequency of water-related disasters. In response to the impact of climate change, risk assessment methodologies need to be developed, and consequence analysis should be conducted to analyze the potential disaster-related health and economic consequences. Integrated models, such as the Integrated Water Resources Management (IWRM), can be used to assess water security by addressing tradeoffs among water users from agriculture, industry, households, and ecosystems.

Moreover, in the face of water service interruptions (due to natural or manmade disasters), water sectors and communities should work together to enhance the resiliency of drinking water and wastewater utilities. The interaction between water science and water policy will ensure water safety and supply, and the security of water environments can be achieved by tracking nutrient enrichment of water resources, climate change adaptation, flood mitigation, and other adaptive environmental management. Overall, this Special Issue will cover issues on water security and resiliency in terrestrial and freshwater environments, the applications of hydrologic sciences, and new water technologies for sustainability.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Environments is an international peer-reviewed open access monthly 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 1800 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.
