“…Most arid land, especially the arid central Asia, is characterized by the typical mountain-oasis-desert ecosystem, in which terminal lakes play a critical role [7]. However, anthropogenic activities related to water resource consumption and land resource excess reclamation have caused a great negative impact on the water balance within tail-end lake basins in the past few decades, leading to the rapid shrinking or drying up of tail-end lakes, such as Ebinur Lake in the western lowest part of the Junggar basin [8], Lop Nor in the Tarim Basin [9], the Aral Sea and Balkhash Lake in central Asia [10][11][12][13], Hamoun Lake [14] and Urmia Lake [15][16][17] in Iran, the Owen Lake and the Salton Sea in USA [18], and Chad Lake in North Africa [19,20]. Salts, heavy metals and other substances that sank to the bottom the lake in the past move to the playa's surface because of the strong evaporation and the capillary effect within the shrinking lake area, forming a salt desert landscape, a unique and distinct landscape in arid central Asia [21,22].…”

A playa usually refers to a salt desert landscape mainly composed of loose and fine lacustrine sediments. Severe wind erosion on a playa causes the playa to become a source of dust and salt dust and poses a threat to vast areas downwind. Currently, little is known about the impact of wind erosion on the particle size distribution of sediments in different landscapes in the playa. In the present study, six dominant different landscapes in a natural state with the same sedimentary environment in the playa of Ebinur Lake were selected to provide insights into the different characteristics of particle size distribution under the effect of long-term wind erosion. The results reveal that the grain-size composition clearly differed among different landscapes. All samples had a common dominant size group consisting of very fine sand and sand. The very fine sand and sand content of Haloxylon ammodendron desert zone (LS5) was the lowest, while the clay and silt content was the highest at both depths among the six landscapes. The lowest clay and silt fraction and highest sand fraction appeared in the herbal desert zone (LS3) at both depths. Almost all of the sediment samples were of a bimodal distribution mode, with significant differences. The cumulative curve showed a similar S-shape, while the probability cumulative curve showed an inverted S-shape with three subpopulations of granularity characteristics. The smallest mean particle diameter appeared in LS5. The majority of the sediments were moderately to poorly sorted. The mean particle size of the sediments from the six landscapes was significantly different (p < 0.05), while no significant difference was observed among the other three parameters. Generally, it can be inferred that LS5 can reduce wind speed effectively, probably due to the smaller leaves and dense branches of Haloxylon ammodendron, which results in a high level of coverage. The results of the present study will have some implications for the grain size characteristics for changes in intensity in regional wind erosion environment and will also have some basis for wind erosion prevention and control in the playa of Ebinur Lake.

“…This may be particularly relevant to the high levels of COVID-19 in Imperial County, California (149). This rural and agriculture-intense inland county has a number of disadvantages as it battles the pandemic including limited access to healthcare, high levels of poverty, obesity, and asthma hospitalizations (209, 211), as well as poor air quality with higher levels of particulate matter exposure than the state or national averages (24,119,212).…”

As countries continue to industrialize, major cities experience diminished air quality, while rural populations also experience poor air quality from sources such as agricultural operations. These exposures to environmental pollution from both rural and populated/industrialized sources have adverse effects on human health. Although respiratory diseases (e.g. asthma and chronic obstructive pulmonary disease) are the most commonly reported following long-term exposure to particulate matter and hazardous chemicals, gastrointestinal complications have also been associated with the increased risk of lung disease from inhalation of polluted air. The interconnectedness of these organ systems has offered valuable insights into the roles of the immune system and the micro/mycobiota as mediators of communication between the lung and the gut during disease states. A topical example of this relationship is provided by reports of multiple gastrointestinal symptoms in patients with coronavirus disease 2019 (COVID-19), while the rapid transmission and increased risk of COVID-19 has been linked to poor air quality and high levels of particulate matter. In this review, we focus on the mechanistic effects of environmental pollution on disease progression with special emphasis on the gut-lung axis.

“…Additionally, constructed ponds have greater eccentricity than natural water bodies and therefore responses to water surface use and transformation (e.g., biogeochemical cycling) may not follow expectations of those observed in natural lakes [80]. Additionally, increasing studies of morphometric properties of natural and constructed water bodies show that changes in shape can result from both anthropogenic and natural drivers of change, including increased withdrawals for human use (e.g., irrigation), climate change, drought, or combinations thereof [81][82][83][84][85]. Any of these factors may impact FPV performance directly by compromising the placement of and connections between FPV panels and/or directly altering generation performance.…”

The Land Sparing, Water Surface Use Efficiency, and Water Surface Transformation of Floating Photovoltaic Solar Energy Installations

Floating photovoltaic solar energy installations (FPVs) represent a new type of water surface use, potentially sparing land needed for agriculture and conservation. However, standardized metrics for the land sparing and resource use efficiencies of FPVs are absent. These metrics are critical to understanding the environmental and ecological impacts that FPVs may potentially exhibit. Here, we compared techno-hydrological and spatial attributes of four FPVs spanning different climatic regimes. Next, we defined and quantified the land sparing and water surface use efficiency (WSUE) of each FPV. Lastly, we coined and calculated the water surface transformation (WST) using generation data at the world’s first FPV (Far Niente Winery, California). The four FPVs spare 59,555 m2 of land and have a mean land sparing ratio of 2.7:1 m2 compared to ground-mounted PVs. Mean direct and total capacity-based WSUE is 94.5 ± 20.1 SD Wm−2 and 35.2 ± 27.4 SD Wm−2, respectively. Direct and total generation-based WST at Far Niente is 9.3 and 13.4 m2 MWh−1 yr−1, respectively; 2.3 times less area than ground-mounted utility-scale PVs. Our results reveal diverse techno-hydrological and spatial attributes of FPVs, the capacity of FPVs to spare land, and the utility of WSUE and WST metrics.
