Special Issue Information
Dear Colleagues,
The sustainability of irrigated agriculture is threatened by reduced water allocations, increased water demand due to climate change and soil degradation. Optimizing water use in agriculture is critical in water-stressed regions. This requires efficient canal and delivery systems, efficient irrigation systems, and effective irrigation timing and management. Replacing surface irrigation systems with sprinkler and drip irrigation systems can increase water use efficiency by 30%.
Irrigation districts are sustainable if the total allocation to farmers and water losses in the system do not exceed the external water inputs and expected water flow and storage in the watershed. In many regions, surface water has been overallocated, which leads to water shortages. Likewise, uncontrolled groundwater pumping eventually results in aquifer depletion and the partial or total collapse of agriculture in a region.
New tools are helping improve irrigation practices. In situ soil moisture sensors, irrigation and water use models, and satellite and drone remote sensing help optimize irrigation scheduling and water productivity. Remote sensing by satellite platforms such as OpenET can also help regulators quantify water use at the farm and district levels.
With reduced irrigation application rates, there is a danger of soil salinization. As such, application depths and irrigation district allocations must account for salinity control.

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.
