Abstract
Spatially explicit cropland greenhouse gas (GHG) emissions and management data are crucial for developing effective climate change mitigation strategies and promoting sustainable agricultural practices. This study presents high-resolution (5 arc-minute) global maps of carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) emissions from agricultural activities across 46 crops circa 2020, referred to as emissions from croplands. Emission sources include synthetic nitrogen fertilizer use, manure application, crop residue incorporation, in-field residue burning, rice cultivation, and drained peatlands for cropping. Our findings indicate that global GHG emissions from croplands reached 2.7 Gt...
