Optimizing manure use and reducing chemical fertilizers are crucial for achieving the Sustainable Development Goals. However, optimal manure redistribution for cropland yield, nitrogen emissions, and greenhouse gas benefit remains unclear at large spatial scales. Here, we employed genetic algorithms and meta-analysis to obtain an optimal substitution rate for major crops in China. This could reduce synthetic nitrogen use and reactive nitrogen pollution by 13.3 and 2.0 Tg, cut ammonia and nitrous oxide emissions by 15.6% and 16.2%, and lower nitrogen runoff and leaching by 32.9%. The yield of eight major upland crops could be increased by 2.0-19.5%. The strategy involves relocating about 255 million pig equivalents, with 32.3% moved across provinces, mainly from central to northern and northeastern China. An estimated US$6.1 billion investment in livestock relocation could yield US$25.9 billion in benefits.
Abstract
Water quality degradation is a major issue in Mediterranean regions, but identifying the key natural and human drivers remains challenging, requiring large–scale studies for meaningful synthesis and comparison. This study analyzed a vast Mediterranean dataset spanning 89,015 across 15 Iberian river basins along a climate gradient (cooler-wetter north to warmer-drier south), 3 decades, 3441 stations, 19 parameters, and 15 million observations. It is the first study of this scale in the region, utilizing custom scripts for automated data compilation and processing. The study revealed an evident north–to–south water quality decline, with rising electric conductivity, pH, total suspended solids, nitrogen, phosphorus, organic carbon, and sulphate, alongside reduced dissolved oxygen and transparency. This pattern correlated with the latitudinal climate gradient and intensified agriculture in the south (Pearson correlation coefficient: 0.1 to 0.53; Spearman's rank correlation coefficient: 0.17 to 0.56), while increased forest cover had a mitigating effect (Pearson: −0.50 to −0.07; Spearman: −0.51 to −0.10). Multidecadal trend analysis revealed a shift around 2005 with most parameters decreasing, except for nitrate and phosphate, which rose likely due to the 2004/05 drought reducing river dilution and expanded irrigated agriculture, especially in Alentejo with the Alqueva reservoir. These findings are crucial for guiding future national management actions and pollution reduction initiatives in Mediterranean regions, aligning with the European Commission's “European Green Deal” that targets a 50 % reduction in nutrient losses to make agriculture more environmentally sustainable, and also provide a valuable reference to many other regions with similar challenges for water quality management.

Abstract Surface displacement caused by natural and anthropogenic activities poses a significant risk to subsurface pipelines, particularly in areas experiencing subsidence. Stress and strain induced by deformation can lead to pipeline buckling and potential vulnerability. This study applies a multidisciplinary approach integrating interferometric synthetic aperture radar (InSAR) deformation analysis, well data, and geological context to assess the risk to oil and gas pipelines in Iran’s Qazvin plain. The focus is on evaluating the impact of an unconfined aquifer, which has a lower risk of subsidence compared to a confined aquifer, on pipeline infrastructure. We analyzed multitemporal Sentinel-1 data collected between 2014 and 2021. Our findings reveal that 2,400 km 2 of the study area is experiencing subsidence with vertical rates reaching up to 14 cm/year with an average S k {S}_{{\rm{k}}} , or skeletal storage value of 0.04. We explore the reasons for this unexpectedly high subsidence, finding that compressible unconfined aquifers with historically low water levels are also at risk for significant inelastic, or permanent, subsidence. We also evaluate pipeline profiles, which show spatial subsidence, much higher than typically seen in unconfined aquifers, with variations of up to 1 m, indicating long-term risks to the infrastructure. This study demonstrates the potential of InSAR techniques in assessing the risk to critical infrastructure, such as oil and gas pipelines, in regions with land deformation due to groundwater withdrawal. Our approach underscores the importance of continuous monitoring and offers valuable insights for addressing the challenges posed by subsidence on pipeline infrastructure.
