Special Issue Information
Agriculture faces the challenge to produce more food to feed the world’s growing population, and irrigation is increasingly important to cope with the required agricultural production. The pressure on water resources is becoming more severe, leading to imbalances between renewable resources and total demands. This jeopardises irrigated agriculture as a non-preferential water use and gives rise to the demand for non-conventional water resources in irrigated agriculture, especially in arid and semi-arid developed countries.
Large-scale supply with desalinated seawater (DSW) has emerged in the last decade as an alternative water-source for sustaining agricultural production in some Mediterranean coastal regions facing persistent water-scarcity and growing high-return crops, as well as in islands lacking fresh-water resources. It represents a steady water-source that effectively removes climatological and hydrological constraints. Consequently, its adoption is increasingly being considered as an alternative water supply for crop irrigation, and this trend is expected to intensify in the near future. However, some certain limiting factors that could become a barrier to DSW spread for crop irrigation, such as high production and allocation energy-requirements, associated greenhouse-gas emissions, and the impact of the high cost of DSW on the farming economy, must be considered. Moreover, there are other agronomic concerns such as the low nutrient concentration of DSW and the consequent increase in the fertigation cost, the crop toxicity risk due to high boron-concentration and cation and anion imbalances, or the sodicity risk affecting soil’s physical properties. Therefore, a great deal of experience and further research are still required to promote reliable, sustainable, and profitable agricultural DSW use.
In this context, this Special Issue of Water is devoted to the research opportunities that this new agricultural irrigation source affords. It is a call for innovative research papers that present irrigation experiences with DSW and advance challenges and new perspectives on this topic. Research will focus on:
- Demonstrative study cases of DSW regional supply for crop irrigation
- Experimental crop trials analysing productivity, production quality, and other agronomic concerns of DSW use
- Agronomic water quality assessment of DSW supplies
- On-farm water-management strategies for promoting the sustainability of DSW use
- Models and decision-support systems for optimising DSW use together with other water sources
- Innovative management technologies for irrigation with DSW
- Adaptation of fertilization to irrigation with DSW
- The water–energy nexus of DSW and effects on agriculture carbon footprint
- DSW cost, price, and impact on the farming economy of specific irrigation areas
- An assessment of the socio-economic impact of agricultural DSW use
- Studies focused on irrigation with (1) reclaimed water entirely produced from urban DSW supplies or (2) desalinated highly saline water from coastal aquifers with seawater intrusion are also welcome.

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 2200 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.
