Summary
This meta-analysis compiled direct N₂O emission measurement data from Mediterranean climate cropping systems to establish empirical emission factors for use in greenhouse gas inventories and life-cycle assessments. The work synthesises heterogeneous field measurement data across Mediterranean regions to provide improved estimates of direct nitrous oxide emissions, as suggested by the participation of multiple measurement specialists and regional experts. The derived emission factors contribute to more accurate regional and global agricultural greenhouse gas accounting.
UK applicability
Whilst focused on Mediterranean climate systems, the meta-analytical methodology and emission factor framework may inform UK agricultural greenhouse gas accounting, particularly for arable cereals grown in southern and eastern England under warmer conditions. The data compilation approach offers a template for similar regional meta-analyses under temperate UK climates.
Key measures
Direct nitrous oxide emissions; emission factors; N₂O flux measurements
Outcomes reported
The study synthesised direct nitrous oxide (N₂O) emission measurements from Mediterranean climate cropping systems to derive empirical emission factors. It quantified N₂O emissions across different cropping practices and management conditions in Mediterranean regions.
