Summary
This review by Bennetzen, Smith and Porter synthesises 40 years of agricultural production and greenhouse gas emission data across world regions to characterise major trends in farming-related climate impacts. As suggested by the title and journal scope, the analysis likely identifies divergent regional patterns in emissions intensity and production efficiency, with implications for understanding agricultural contribution to global climate change and identifying leverage points for emissions reduction.
UK applicability
UK agricultural emissions data and trends are likely represented within the European or developed-nations cluster, allowing comparison of UK farm systems against global and regional benchmarks. The findings may inform UK Climate Change Committee advice and Farm to Fork policy development regarding sectoral decarbonisation targets.
Key measures
Greenhouse gas emissions (likely CO₂, CH₄, N₂O equivalent); agricultural production output by region; emissions intensity; temporal trends 1975–2015
Outcomes reported
The study tracked agricultural production and associated greenhouse gas emissions across world regions over a 40-year period. It analysed major temporal and geographical trends in GHG emissions intensity and absolute emissions from farming systems.
