Abstract The increasing global demand for farmland products is placing unprecedented pressure on the agricultural system and its water resources. Many regions of world, that are affected by a chronic scarcity relative to their population, strongly depend import commodities associated embodied (or virtual ) water. globalization through trade (VWT) leading displacement use disconnection between human populations resources they rely on. Despite recognized importance these phenomena in reshaping patterns dependence teleconnections consumers producers, effect regional has just started be quantified. This review investigates spatiotemporal dynamics, drivers, impacts VWT an integrated analysis surface water, groundwater, root-zone soil moisture consumption production; it evaluates how flows compare major ‘physical fluxes’ Earth System; provides new reconceptualization hydrologic cycle account also role redistribution hidden ‘virtual cycle’.

Abstract Much of the world’s data are stored, managed, and distributed by centers. Data centers require a tremendous amount energy to operate, accounting for around 1.8% electricity use in United States. Large amounts water also required operate centers, both directly liquid cooling indirectly produce electricity. For first time, we calculate spatially-detailed carbon footprints operating within States, which is home one-quarter all center servers globally. Our bottom-up approach reveals one-fifth direct footprint comes from moderately highly stressed watersheds, while nearly half fully or partially powered power plants located regions. Approximately 0.5% total US greenhouse gas emissions attributed We investigate tradeoffs synergies between center’s utilization strategically locating areas country that will minimize one more environmental footprints. study quantifies implications behind our creation storage shows path decrease increasing digital footprint.

Understanding the water use of power production is an important step to both a sustainable energy transition and improved understanding conservation measures. However, there are large differences across literature that currently present barriers decision making. Here, compiled inventory blue from existing studies allowed uncover characteristics investigate current uncertainties. The results show photovoltaics, wind power, run-of-the-river hydropower consume relatively little water, whereas reservoir woody herbaceous biomass can have extremely footprint. consumption differ greatly countries due different geographic conditions. Only few provided values for influencing factors use, such as capacity factor. Values reported came mainly assumptions other rather than direct measurement. Omitting life cycle stage may lead significant underestimations. Water scarcity attracting more attention, but not useable regional comparison data gaps inconsistent measurements. In future, clear detailed definition footprint system boundary essential improving comparisons systems modelling.

Abstract Cities have grown rapidly—while they provide opportunities for many, must also confront pervasive and rising inequality, unsustainable consumption, growing vulnerability to the impacts of climate change. Recent research emphasizes need improve urban resilience sustainability in face change, but offers circumscribed approaches that mostly focus on either (1) resource management service provision, (2) social processes capacities transformation, or (3) governance power relations among actors. Here, we embrace emerging approach considers areas as interdependent social-ecological-technological systems (SETS) consider implications sustainable provision; role bottom-up efforts initiating transformations; how may, under certain conditions, coordinate these effect broader

Water is essential for thermal energy and electricity generation. To help clarify water–energy interdependencies in China, a life-cycle water footprint evaluation framework was developed based on the product concept assessment methods to assess coal-fired power generation China. The applied quantitatively analyze virtual provincial consumption by China 2016 its impact quality. results revealed of ∼6.60 m3/MWhel, where blue accounted 24.8% grey 75.2% total. industry main industrial consumer, total 26.03 billion m3. Because coal transportation transmission are driven spatial asynchrony production consumption, flowed from water-scarce Northwest water-rich East annual output Shanxi, Inner Mongolia, 498.2 million m3, representing 33% regional footprint. These findings can be used improve understanding patterns resources inform coordinated development resource management.

Climate change is expected to affect the availability of water for electricity generation, yet propagation climate impacts across a large and diverse power grid remains unexplored. In this study, we evaluate how projected changes in generation at hydroelectric thermal plants coincident propagate locally throughout interconnected western United States. We also whether prospect climate-driven could regional dependencies. Hydrologic simulations derived from three Global Circulation Models (CCSM4, INMCM4, GFDL-CM3), two radiative scenarios (RCP4.5 RCP8.5) VIC hydrology model are used force large-scale, distributed management (MOSART-WM), which translates into constraints hydropower water-dependent thermoelectric plants. Power system dynamics evaluated using production cost PLEXOS. find that interregional connections contemporary Western U.S. infrastructure play an essential role managing variations due hydrological variability.
