FAOSTAT data estimates nitrous oxide emissions from agricultural soils globally, computed using IPCC Tier 1 methodology. Estimates are available by country for the period 1961 to 2019, with projections to 2030 and 2050 for some categories. The database is updated annually by the Food and Agriculture Organization.
Use Cases
- Analyze trends in N2O emissions by country over the 1961-2019 period to assess the impact of agricultural practices.
- Model future emissions scenarios using the provided 2030 and 2050 projections for key categories.
- Calculate aggregate CO2 equivalent emissions using the IPCC AR5 global warming potentials applied to the CH4, N2O, and CO2 data.
- Compare emissions from agricultural soils against other emission categories within the FAOSTAT Emissions Totals domain.
Strengths
- Global country-level coverage for a 58-year period (1961-2019).
- Data computed using a standardized IPCC Tier 1 methodology for comparability.
- Includes future projections (2030, 2050) for some emission categories.
Limitations
- Specific row and column counts are unknown, limiting assessment of granularity.
- Methodology is at Tier 1 (simplified), not the more detailed Tier 2 or 3 levels.
- Data for some categories only covers 1990-2019, creating inconsistent time series.
