Towards agro-environmentally sustainable irrigation with treated produced water in hyper-arid environments
Produced water (PW) is the main waste stream generated from oil and gas extraction. Nowadays, half of the global PW volume is managed through environmentally controversial and expensive disposal practices, such as re-injection through deep wells. In dry areas such as in the Arabian Peninsula, PW could be reused to irrigate crops, creating environmental, economic and social value. However, the quality of most PWs remains challenging as their high salinity, sodicity and alkalinity can degrade soil fertility and crop yield.

Influence of irrigation time and frequency on greenhouse gas emissions in a solid-set sprinkler-irrigated maize under Mediterranean conditions
Irrigation management may influence soil greenhouse gas emissions (GHG). Solid-set sprinkler irrigation systems allow to modify the irrigation time and frequency. The objective of this study was to quantify the effect of two irrigation times (daytime, D; nighttime, N)and two irrigation frequencies (low, L; high, H)on soil carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O)emissions in a solid-set sprinkler-irrigated maize (Zea mays L.)field located in NE Spain during 2015 and 2016 growing seasons and the fallow period between growing seasons.
