The blue and grey water footprints of date production in the saline and hyper-arid deserts of United Arab Emirates

Tomatoes from the desert: Environmental footprints and sustainability potential in a changing world

“…As pointed out in a recent study (Fridman et al, 2021), approaches to calculating WF usually refers to rainfall (green water) and fresh irrigation water (blue water) and tend to ignore the other water sources. As in some rare previous studies in hyperarid climate (e.g., Al-Muaini et al, 2019), the negligible annual precipitation was found to be irrelevant for crop irrigation; therefore, the WF of a studied hyperarid system should focus on blue water (Chapagain and Hoekstra, 2004) and includes brackish water used for irrigation and desalinated water used in the packing houses (Fridman et al, 2021).…”

Water use indicators and economic analysis for on-farm irrigation decision: A case study of a super high density olive tree orchard

“…that flows below root depth, may become green again if the level of the water table increases and reaches the root zone; and on 3assessing the grey fraction, among other things because the grey water footprint depends on the downstream use, being minimal if the downstream use is hydropower or navigation, but substantial if the downstream use involves swimming, fishing or drinking. Al-Muaini et al (2019) quantified the blue and grey (for nitrogen and salt)…”

Groundwater Recharge Estimation Using In-Situ and Grace Observations in the Eastern Region of the United Arab Emirates

“…The major crop grown in the region is palm tree and the irrigation rate per hectare (1 ha = 100 palm trees) varies in the region due to the lack of knowledge of farmers to the required irrigation amount (Alomran et al, 2019). Thus, for simplicity, the irrigation rate used for the irrigation return flow calculation is averaged from multiple papers, which is 13,700 m 3 /ha (Al-Muaini et al, 2019;Alomran et al, 2019;Al Tenaiji et al, 2021).…”
