Observations
Satellite data +Surface measurements
CO, NOx, PM10, PM2.5, BC

Primary aerosols - Implemented

Secondary aerosols – Under development• Agricultural activities constitute the main NH3 emission sources andArgentina’s economy is based on agro-activities.

Motivation• No NH3 emission inventories in Argentina.
• Global inventories does not reflect the important changes that took placein the agricultural practices.

Results I• Emissions from manure-related activities constituted the main sourceof NH3, accounting for ~60% of the total (including manure
management & manure in pasture), of which almost a halfcorresponds to beef cattle.
• Crop fertilization with urea was the main single source of NH3,
contributing around 30% of total emissions.

ConclusionsFirst bottom-up national inventory of NH3 emissions from agricultural activities
2000–2012



Additional data (non-key categories ) of N2O AD collected for NC is required tobuild NH3 emission inventory.

Trends in temporal-spatial patterns reflect the influence of the tree maindrivers



Climate changeMarket expansion

Technological changes

Relevant differences with EDGARActivity data: use of fertilizers, poultry, other livestock, % of feedlots,cattle farming practices

Allocation: Manure management – Manure in pastureAssignation of fires: land use – land use changes – agricultural wasteburning

Spatial displacement driven by

Increase in soybean area planted that led to the displacement ofcultivation areas of N-fertilized crops.

The intensification of cattle production systems in feedlots.
