“…Modelling studies also indicate that groundwaterfed irrigation increases ET by 4% over the continental United States (Ozdogan et al 2010) and increases downwind precipitation by 15-30% in the high plains of the United States in July (De Angelis et al 2010). Similar effects are found in response to anthropogenic groundwater exploitation by Zen et al (2017) and Zou et al (2014), at global and at regional scales, respectively.…”

125°S-60°S) are significantly impacted by the WT, showing a decrease in air temperature (−0.5 K over mid-latitudes and −1 K over tropics) and an increase in precipitation. The latter can be explained by more vigorous updrafts due to an increased meridional temperature gradient between the equator and higher latitudes, which transports more water vapour upward, causing a positive precipitation change in the ascending branch. Over the West African Monsoon and Australian Monsoon regions, the precipitation changes in both intensity (increases) and location (poleward). The more intense convection and the change of the large-scale dynamics are responsible for this change. Transition zones, such as the Mediterranean area and central North America, are also impacted, with strengthened convection resulting from increased ET.

“…In recent decades, through the anthropogenic nitrogen discharge from activities such as fertilizer application, fossil fuel consumption, and leguminous crop production, the amount of biologically available nutrients entering the terrestrial ecosystem has more than doubled in comparison to preindustrial era levels (Galloway et al, ). Humans have also greatly altered global hydrological systems by extracting groundwater and water from major rivers (Haddeland et al, ; Pokhrel, Hanasaki, Wada, & Kim, ; Zeng, Xie, & Zou, ). For example, irrigation can result in an increase in soil nitrogen leaching (Woli, Hoogenboom, & Alva, ), while dams can inadvertently detain considerable nutrients that would otherwise be carried by rivers to oceans (Maavara et al, ; Van Cappellen & Maavara, ).…”

Excess nutrients from fertilizer application, pollution discharge, and water regulations outflow through rivers from lands to oceans, seriously impacting coastal ecosystems. A reasonable representation of these processes in land surface models and River Transport Models (RTMs) is very important for understanding human–environment interactions. In this study, the schemes of riverine dissolved inorganic nitrogen (DIN) transport and human activities including nitrogen discharge and water regulation, were synchronously incorporated into a land surface model coupled with a RTM. The effects of anthropogenic nitrogen discharge on the DIN transport in rivers were studied based on simulations of the period 1991–2010 throughout the entire world, conducted using the developed model, which had a spatial resolution of about 1° for land processes and 0.5° for river transport, and data on fertilizer application, point source pollution, and water use. Our results showed that rivers in western Europe and eastern China were seriously polluted, on average, at a rate of 5,000–15,000 tons per year. In the Yangtze River Basin, the amount of point source pollution in 2010 was about four times more than that in 1991, while the amount of fertilizer used in 2010 doubled, which resulted in the increased riverine DIN levels. Further comparisons suggested that the riverine DIN in the USA was affected primarily by nitrogen fertilizer use, the changes in DIN flow rate in European rivers was dominated by point source pollution, and rivers in China were seriously polluted by both the two pollution sources. The total anthropogenic impact on the DIN exported to the Pacific Ocean has increased from 10% to 30%, more significantly than other oceans. In general, our results indicated that incorporating the schemes of nitrogen transport and human activities into land surface models could be an effective way to monitor global river water quality and diagnose the performance of the land surface modeling.

“…For recycled water, on the one hand, it is good for environmental protection to decrease waste water discharge. On the other hand, recycled water as a new technology will undoubtedly have potential risks for users for various reasons [15][16][17][18]. Therefore, recycled water use is an action that is good for society but harmful to oneself.…”

Abstract:In order to explore the influence mechanism of traditional Chinese culture values on urban residents' acceptance of the reuse of recycled water, this paper selects interdependent self-constructional indicators representing the dependency relation between people as the representative of traditional culture values. In this paper, interdependent self-constructional indicators are introduced based on a technology acceptance model (TAM), in order to establish a hypothesis model. Following this, the writer conducts a study that shows the influence on the acceptance of recycled water through the formation of interdependent self-construction. Finally, the influence mechanism of traditional cultural values on citizens' behavior regarding the reuse of recycled water is determined. To start with, the writer verifies the reliability and validity of data from 584 samples, and then tests the goodness-of-fit between the sample data and the hypothesis model by AMOS21.0 (software). On this basis, the writer analyzes the direct and indirect influence through the hypothesis model and finds that the interdependent self-constructional intensity will accelerate the acceptance process of recycled water technology by positively influencing a change in the residents' attitudes to recycled water. The conclusion shows that traditional Chinese cultural values have a certain influence on urban residents' acceptance of the reuse of recycled water. Meanwhile, the writer clarifies the influence's mechanism.
