Special Issue Information
Dear Colleagues,
One of the greatest current challenges to the development of sustainable agriculture is in meeting the food needs of a global growing population while preserving minimum impacts on water shortage, land and environmental degradation. Sustainable agricultural practices using cleaner technologies, such as high-efficient irrigation methods and precisely controlled fertigation, benefit both crop production and environment protection. Moreover, water scarcity has become key obstacle threatening world food security, and sustainable social development around the world. Consequently, the shortages of water resources have accentuated our reliance on low-quality irrigation waters (brackish water, saline water, reclaimed water), which can be effectively utilized to address the irrigation water demands. Drip irrigation system, due to their characteristics of precise water distribution and prevention of aerosol release to plants and the environment, are highly recommended for low-quality water irrigation. Previous research results suggested drip irrigation also resulted in higher crop yield and irrigation water-use efficiency when compared to traditional irrigation methods. However, the presence of huge amounts of scaling ions (Ca2+, Mg2+, HCO3− , SO42− etc.), colloidal particles and natural organic matter in low-quality irrigation waters leads to multi-factor failure in drip irrigation systems. In addition, most synthetic fertilizers are incompatible in low-quality irrigation waters, which will further trigger the risk of failure of the drip irrigation system.
This Special Issue of Water intends to collect some of the latest research advancement and innovations in drip irrigation systems for effective management and sustainable utilization of low-quality irrigation waters in drip irrigation systems in order to alleviate the contradiction between supply and demand of agricultural water resources, ensure agricultural soil protection, crop yield and quality, and enhance the farmers’ enthusiasm for drip irrigation technology.

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.
