Global management of saline soils to boost crop yields and halve nitrogen losses
Abstract Global soil salinity threatens food security and accelerates environmental degradation. However, the dual impacts of salinization on crop productivity and nitrogen dynamics have not been comprehensively quantified. Here we developed a spatially explicit nitrogen budget for global saline croplands and applied a pairwise comparison framework to assess salinity-induced changes in crop yields and reactive nitrogen (Nr) losses.
Climate change and interprovincial trade move grain production and environmental burdens northwards in China
Abstract Understanding how the grain trade redistributes environmental burdens across regions is critical for designing equitable food security and environmental stewardship policies. Using grain production, trade and environmental data from 1980 to 2020, we quantify environmental spillovers embedded in China’s interprovincial grain trade, identify their socio-economic and climatic drivers, project future scenarios and estimate ecological compensation schemes.
Integrated climate effects on nitrogen cycles in global grasslands
Abstract Grasslands play a crucial role in providing essential ecosystem services through biogeochemical processes. Improving grassland productivity and nitrogen use efficiency, reducing reactive nitrogen losses, and ensuring environmental sustainability represent major challenges, especially under the influence of global climate change.
