Abstract Emerging interdisciplinary science efforts are providing new understanding of the interdependence food, energy, and water (FEW) systems. These advances, in turn, provide critical information for coordinated management to improve affordability, reliability, environmental sustainability FEW Here we describe current state nexus approaches managing resource conflicts through reducing demand increasing supplies, storage, transport. Despite significant advances within past decade, there...
Abstract Traditional infrastructure adaptation to extreme weather events (and now climate change) has typically been techno‐centric and heavily grounded in robustness—the capacity prevent or minimize disruptions via a risk‐based approach that emphasizes control, armoring, strengthening (e.g., raising the height of levees). However, nonclimate challenges facing are not purely technological. Ecological social systems also warrant consideration manage issues overconfidence, inflexibility,...
Abstract Persistent overuse of water supplies from the Colorado River during recent decades has substantially depleted large storage reservoirs and triggered mandatory cutbacks in use. The river holds critical importance to more than 40 million people two hectares cropland. Therefore, a full accounting where river’s goes en route its delta is necessary. Detailed knowledge how used can aid design strategies plans for bringing use into balance with available supplies. Here we apply...
Ecohydrological systems may be characterized as nonlinear, complex, open dissipative systems. Such consist of many coupled processes, and the couplings change depending on system state or scale in space time at which is analyzed. The arrangement a complex represented network information flow feedback between variables that measure processes. occurrence such provides sufficient conditions for self‐organized nonlinear behaviors to emerge. We adapt an information‐theoretic statistical method...
Abstract Methane (CH 4 ) exchange in wetlands is complex, involving nonlinear asynchronous processes across diverse time scales. These and scales are poorly characterized at the whole‐ecosystem level, yet crucial for accurate representation of CH process models. We used a combination wavelet analysis information theory to analyze interactions between flux biophysical drivers two restored Northern California from hourly seasonal scales, explicitly questioning assumptions linear, synchronous,...
A multi-method approach estimating summer waste heat emissions from anthropogenic activities (QF) was applied for a major subtropical city (Phoenix, AZ). These included detailed, quality-controlled inventories of city-wide population density and traffic counts to estimate vehicular sources respectively, also simulations derived urban electrical consumption generated by coupled building energy – regional climate model (WRF-BEM + BEP). component QF data were subsequently summed mapped through...
In this study we characterized the relationship between temperature and mortality in central Arizona desert cities that have an extremely hot climate. Relationships daily maximum apparent (ATmax) for eight condition-specific causes all-cause deaths were modeled all residents separately males females ages <65 ≥65 during months May–October years 2000–2008. The most robust was ATmax on day of death from direct exposure to high environmental heat. For cause death, heat thresholds gender age...
Abstract Urban ecosystems are widely hypothesized to be more ecologically homogeneous than natural ecosystems. We argue that urban plant communities assemble from a complex mix of horticultural and regional species pools, evaluate the homogenization hypothesis by comparing cultivated spontaneously occurring vegetation area across seven major U.S. cities. There was limited support for diversity , as spontaneous yard flora had greater numbers areas, phylogenetic also greater. However, yards...
Abstract We propose a conceptual and theoretical foundation for information-based model benchmarking process diagnostics that provides diagnostic insight into performance realism. benchmark against bounded estimate of the information contained in inputs to obtain lost due error, we perform process-level by taking differences between modeled versus observed transfer entropy networks. use this methodology reanalyze recent Protocol Analysis Land Surface Models (PALS) Model Benchmarking...
Abstract Interbasin water transfers (IBTs) can have a significant impact on the environment, availability, and economies within basins importing exporting water, as well downstream of these transfers. The lack comprehensive data identifying describing IBTs inhibits understanding role play in supplying for society, their collective hydrologic impact. We develop three connected datasets inventorying United States Canada, including features, geospatial details, transfer volumes. surveyed...
There is no consensus on how changes in both temperature and precipitation will affect regional vegetation. We investigated controls hydrologic partitioning at the catchment scale across many different ecoregions, compared resulting estimates of wetting vaporization (evapotranspiration) to remotely sensed indices vegetation greenness. The fraction vaporized by plants, known as Horton index, strongly related ratio available energy water Earth's surface, aridity index. Here we show that index...
Observations of local-scale urban surface energy balance (SEB), which include fluxes net all-wave radiation (Q*), and eddy covariance measurements sensible (QH) latent heat (QE) were collected in an arid Phoenix, AZ suburb from January to December 2012. We studied diurnal variations SEB partitioning over four distinct seasons: winter, equinoxes, summer; the latter period is further subdivided into (1) months prior (2) occurring during North American Monsoon. Largest flux densities observed...
Nearly one-sixth of U.S. river basins are unable to consistently meet societal water demands while also providing sufficient for the environment. Water scarcity is expected intensify and spread as populations increase, new emerge, climate changes. Improving productivity by meeting realistic benchmarks all users could allow communities expand economic activity improve environmental flows. Here we utilize a spatially detailed database set over 400 industries products. We assess unrealized...
