DESCRIPTION:Peatlands and other organic soils occupy a small fraction of th
 e land surface but store a large share of the global soil carbon. Drainage
  and fire in these systems are major sources of greenhouse gas (GHG) emiss
 ions\, yet remain poorly mapped. Remote sensing enables global monitoring 
 of proxies for peatland disturbance\, but no monitoring system currently l
 inks the extent of organic soils\, disturbance\, and emissions at high spa
 tial resolution. Here we develop a 0.00025° (approximately 30 m) global g
 eospatial framework that overlays organic soils extent with multi-temporal
  land cover and land use data\, drainage infrastructure\, plantations\, pe
 at extraction areas\, coastal wetlands\, and burned area to delineate dist
 urbed organic soils. Using IPCC Wetlands Supplement default (Tier 1) metho
 ds\, we estimate CO2\, CH4\, N2O\, and CO emissions for disturbed organic 
 soils over 2001–2024. Baseline results indicate that disturbed organic s
 oils emitted about 4.9 Gt CO2e yr-1 (4.5–5.1 Gt CO2e yr-1 across five in
 ventory periods)\, with roughly three quarters from drainage and one quart
 er from fires. Emissions and disturbed area are heavily concentrated in a 
 small group of countries and land uses\, dominated by Russia and Indonesia
 \, particularly cropland and settlements in boreal and temperate zones and
  plantations on organic soils in the tropics. Sensitivity experiments that
  vary the extent of organic soils\, the drainage radius around infrastruct
 ure\, and IPCC default (Tier 1) emission factors yield a plausible range o
 f approximately 3–7 Gt CO2e yr-1. These estimates should not be interpre
 ted as a correction to existing peatland-specific emission estimates\, but
  as complementary\, more comprehensive monitoring of disturbed organic soi
 l systems under a harmonized\, globally consistent framework. The resultin
 g 30 m global maps of organic soil state\, disturbance\, and emissions dem
 onstrate how multi-temporal Earth observation can be combined with GHG inv
 entory methods to monitor peatland disturbance drivers\, identify high-emi
 tting hotspots\, and provide an updatable resource for inventories\, natio
 nally determined contributions\, and peatland conservation and restoration
  planning.
