“…The farmland received irrigation of 442.7 mm/year per unit, more than three times of the green water stored in the soil. This follows the nature of arid regions that the water is limited for agriculture which requires a lot more water through irrigation (Al-Zu'bi, 2007). The forest also received 171.5 mm/year irrigated water and the irrigation for grassland is only 36.2 mm/year.…”

Abstract. Water resources assessment is crucial for human well-being and ecosystem's health. Assessments by considering both the blue and green water are of great significance as the green water plays a critical but often ignored role in the terrestrial ecosystem, especially in arid and semi-arid regions. Many approaches have been developed for green and blue 10 water valuation, while few of them considers the interrelationship between them. This study proposed a new framework for green and blue water assessment by considering the interactions between them in an arid endorheic river basin where hydrological cycling is dramatically altered by human activities. Results show that even though the green water is the dominant water resources, the blue water is also critical. Most of the blue water are transformed to green water through physically and human induced processes to meet the water demand of ecosystems. Time and spatial variability of water 15 supply and consumption forms totally different blue and green water regimes in different ecosystems. We also found that human use an increasing share of water with the decrease of the water availability. The massive water use by human reduces the water use for natural ecosystems. This indicates that natural ecosystems will take a higher risk of freshwater use when the water use competition increases. This study provides crucial information to better understand the interactions between green and blue water by assessing water resources in an explicit way. It also provides crucial implications for water 20 management aiming to make the balance between humankind and nature.

“…As demonstrated by numerous researchers (e.g., Amé-zketa 1999; Tedeschi and Dell'Aquila 2005;Al-Zu'bi Y 2007;Huang et al 2011;Askri et al 2014), frequent irrigation with saline water can accelerate the soil salinization process, significantly degrading the quality of agricultural soil in various ways. A high concentration of salt, especially sodium salt, in the soil can cause physicochemical deterioration of the soil.…”

“…This can lead to structural damage to the soil due to the dispersion of clay particles, decreased soil hydraulic conductivity, soil instability due to the clogging of soil pores, and the formation of a thin crust at the surface of the soil, which reduces the rate of infiltration of irrigation water into the soil profile. Physicochemical deterioration of the soil also leads to a severe reduction in soil productivity, hence degrading soil fertility (Al-Zu'bi 2007).…”

When saline water is used to irrigate crops in arid environments, appropriate irrigation management should be applied to avoid negatively impacting soil characteristics. In this study, the effects of irrigating date palms with saline water (2.24 g l −1 ) on soil physicochemical characteristics such as the electrical conductivity (EC e ), the pH of the saturated soil paste (pH e ), the concentrations of soluble cations (Ca 2+ , Mg 2+ , Na + ), the sodium adsorption ratio (SAR), the saturated soil hydraulic conductivity (K s ), and the volumetric water content of the soil (θ v ) were evaluated in a Tunisian Saharan cropland, the Dergine Oasis, during a 4-year period (2012)(2013)(2014)(2015). The effects of three different irrigation treatments of date palms on soil properties were investigated: low treatment (90% of the net irrigation requirement (NIR) of date palms was applied); medium treatment (100% of NIR was applied), and high treatment (110% of NIR was applied). The results showed that the application of saline water for irrigation inevitably has a negative impact on the physicochemical properties of the soil. Irrigation with saline water was observed to have severe negative impacts on the soil characteristics, especially EC e , Na + , K s , and θ v . However, among the three irrigation treatments applied, statistical analysis (Duncan's multiple range test) indicated that the high treatment significantly (p < 0.05) minimized the degradation of soil characteristics by the saline water; this treatment decreased EC e , Na + , and SAR and increased the water content, θ v , of the studied soil.

Jordan faces great internal water scarcity and pollution, conflict over trans-boundary waters, and strong dependency on external water resources through trade. This paper analyzes these issues and subsequently reviews options to reduce the risk of extreme water scarcity and dependency. Based on estimates of water footprint, water availability, and virtual water trade, we find that groundwater consumption is nearly double the groundwater availability, water pollution aggravates blue water scarcity, and Jordan's external virtual water import dependency is 86%. The review of response options yields 10 ingredients for a strategy for Jordan to mitigate the risks of extreme water scarcity and dependency. With respect to these ingredients, Jordan's current water policy requires a strong redirection towards water demand management. Actual implementation of the plans in the national water strategy (against existing oppositions) would be a first step. However, more attention should be paid to reducing water demand by changing the consumption pattern of Jordanian consumers. Moreover, unsustainable exploitation of the fossil Disi aquifer should soon be halted and planned desalination projects require careful consideration regarding the sustainability of their energy supply.
