Our results indicate the following: (1) from 2001 to 2020, China's crop productivity increased by approximately 0.11 kgCm<sup>-2</sup>yr<sup>-1</sup>, which compensated for the decline in crop yields caused by a reduction in cropland area.

To establish a causal relationship between the check dams and C and nutrient variations, we first determined soil deposition depth post-check dam construction in both a natural mangrove and a neighboring check dam-affected mangrove. We then analyzed the C, N, and P content, stoichiometry, and their depth-dependence in soil systems-including bulk soil, microbial biomass, and extracellular enzymes-at depths of 0-100 cm across three vegetation types. Our results indicated that check dam significantly increased the contents of C, N, and P within the soil-microorganism-enzyme system by15.42%-851.15%, and enhanced the stoichiometry of soil C:P and N:P by 79.81%-94.48%. Check dams also enhanced the depth-dependence of soil C, with C varying more slowly than N and P in the natural mangrove but faster in the check dam-affected mangrove. These findings demonstrate that check dams can significantly promote C accumulation in mangroves. Structural equation models revealed that check dam-induced hydrological processes primarily affected C, N, and P content by regulating soil physical properties, while influenced C:N:P stoichiometry through basic chemical properties.

To evaluate this approach, for LU playa, we examined the accumulation of ions, minerals deposition, and salt crust (Cr) formation in LU brine under both natural and laboratory conditions. We then assessed the effect of brines with varying Mg<sup>2+</sup> concentrations (B0 ≈1.97, B5 ≈2.72, and B15 ≈ 3.62 mol/L) on the stabilization of two highly erodible soils (sand sheets and sandy salt crust), comparing them with commercial stabilizers: sodium alginate (Na-A) and sodium silicate (Na-S). The crusts were evaluated based on thickness, compressive strength, and soil loss in wind tunnel experiments. Scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS) was employed to analyze crust morphology and elemental composition. The results indicated that in the pure crusts, halite was the dominant mineral in salt crusts, while bischofite (MgCl₂∙6H₂O) and epsomite (MgSO₄∙7H₂O) formed during different stages of brine evaporation. Bischofite appeared at the pond margins, indicating deposition from less concentrated brines (B<sub>0</sub> and B<sub>5</sub>), while epsomite dominated the center during the final evaporation stages. Brine treatments significantly reduced soil loss to 1.2%, outperforming Na-A (4.88%), Na-S (30.35%), and the control (34.18%).

Few studies have quantified groundwater and surface water quality downgradient from malfunctioning OWSs. Thus, the goal of this study was to quantify nutrients and Escherichia coli in shallow groundwater and adjacent streams downgradient from malfunctioning OWSs.

Sites were sampled 10 times between Feb 2022 and Apr 2023. Samples were analyzed for nutrients, E. coli, and other water quality parameters. Results indicated that groundwater was typically within 30 cm of the trench bottom at 2 sites (Sites 100 and 200), thus these OWSs were malfunctioning for insufficient vertical separation distance. Groundwater beneath the 2 malfunctioning drainfields contained median concentrations of TDN (17.98 mg L<sup>-1</sup>), TDP (0.34 mg L<sup>-1</sup>), and E. coli (2419.6 MPN 100 mL<sup>-1</sup>) that were approximately 19, 34, and 576 times greater than concentrations in background groundwater.
