Special Issue Information

Dear Colleagues,

Cropping systems are fundamental to global agroecosystems, providing essential goods such as food and fiber and delivering critical ecosystem services. Integrating cropping and livestock systems holds significant promise in enhancing production efficiency and overall productivity and mitigating economic risks while promoting agricultural sustainability. Despite these benefits, the adoption of integrated crop–livestock systems remains limited in modern agricultural practices. A deeper understanding is needed regarding the impacts of livestock integration on cropping systems, the influence of management practices on productivity and sustainability, and the socio-economic barriers that may impede widespread adoption.

This Special Issue aims to highlight innovative research and best practices in the integrated management of cropping and livestock systems, with an emphasis on economically viable and environmentally sustainable approaches. We welcome original research articles, reviews, and case studies that address a range of topics. These include, but are not limited to, the following:

  • Management strategies for integrated systems;
  • Plant–animal interactions;
  • Soil health;
  • Hydrologic and nutrient cycling processes;
  • Innovative solutions to current integration challenges.

We seek contributions that advance the scientific understanding and practical implementation of integrated cropping–livestock systems in diverse agricultural contexts.

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 250 words) can be sent to the Editorial Office for assessment.

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. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Water scarcity has become a major challenge for agriculture, particularly in arid and semi-arid regions where irrigation is essential for sustaining crop and forage production. As freshwater supplies face growing pressure from climate change, urban growth, and industrial use, there is increasing interest in exploring alternative water sources to support sustainable agriculture. Produced water, a byproduct of oil and gas extraction, may represent an alternative water source in water-limited regions like the southwestern United States and the Middle East. However, raw produced water often contains high levels of salinity, trace metals, hydrocarbons, and naturally occurring radioactive materials, which cause risks to soils, crops, livestock, and food systems. This review synthesizes peer-reviewed studies up to January 2026 and reports on the agricultural application of treated produced water, focusing on its effects on soil properties, crop growth, yield, and forage nutritive quality. Existing research shows that treated produced water could be used for grain as well as forage crops under controlled conditions, but poorly treated and managed applications can lead to increases in soil salinity, structural degradation, reduced nutrient uptake, and hindered crop performance. In forage systems, irrigation with treated produced water has also been associated with changes in nutritive value, increasing concerns for livestock health. Several knowledge gaps remain, including limited long-term field studies, insufficient information on crop-specific contaminant thresholds, incomplete assessment of treatment and remediation strategies under different environmental conditions, and the absence of a consistent framework for classifying the chemistry of treated produced water for agricultural applications. Addressing these gaps through integrated soil, crop, and water research and the development of clear policies and guidelines is essential for determining whether treated produced water can be safely and sustainably used in agriculture under growing water scarcity.
