Special Issue Information
Dear Colleagues,
Food security is a common objective in many agricultural systems, which is also closely linked to water security, since food production heavily depends on water availability around the world. Water shortage has seriously affected China’s agricultural production over the last 50 years. To mitigate the water shortage problem, it is essential to reduce the irrigation amount. However, simply reducing irrigation water without diligent planning would lead to the agricultural productivity reductions, thus posing a great risk to national food security. Therefore, the balance between alleviating water shortage and maintaining high and stable agricultural production is a very important issue. In addition, it is essential that the water use efficiency and management is improved, striking a balance between, on one hand, increasing economic productivity and, on the other hand, increasing the amount of irrigation water necessary for this increased economic productivity, while decreasing the negative environmental impacts associated with this practice. Therefore, improving water use efficiency is the key to ensure food security and to reduce irrigation water use.
This Special Issue calls for contributions on the following non-exclusive list of topics:
- irrigation strategies and technologies for improving water use efficiency,
- irrigation water management and modeling under climate change scenarios,
- crop physiological response to deficit irrigation,
- irrigation water management for health soil physical and chemical properties.

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. 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.
