Summary
This paper synthesises long-term data on agricultural production and greenhouse gas emissions across world regions, examining how production growth has been coupled with (or decoupled from) emission trajectories over four decades. The analysis reveals major regional and sectoral trends, identifying where agricultural intensification has driven emission increases and where efficiency or structural changes may have modulated emissions relative to output. The work contributes to understanding the scale and geography of agriculture's climate footprint and the policy implications for emissions mitigation in different contexts.
UK applicability
The findings provide contextual benchmarking for UK agricultural emissions and production trends within a global framework, potentially informing UK climate policy targets for the agricultural sector and identifying comparative efficiency opportunities across regions and commodities.
Key measures
Agricultural production volumes by crop and livestock type; greenhouse gas emissions (CO₂, CH₄, N₂O) by region and agricultural subsector; temporal trends over 40-year period
Outcomes reported
The study analysed long-term trends (approximately 1961–2001) in agricultural production and associated greenhouse gas emissions across major world regions. It quantified relationships between production growth and GHG emission changes, identifying regional patterns and sectoral contributions.
