Summary
This systems dynamics modelling study integrated cropping system, regional climate, and agronomic management variables to assess lifecycle greenhouse gas emissions from biodiesel feedstock production in the United States. The work examined canola production in the inland Pacific Northwest and soybean production in the Midwest under variable nitrogen use efficiency and agroecological conditions, as suggested by the methodology, aiming to provide spatially-resolved estimates of GHG mitigation potential to support climate-informed biofuel crop expansion planning.
UK applicability
Direct applicability to UK conditions is limited, as the study focuses on North American cropping systems (canola and soybeans) and agroecological zones. However, the systems dynamics modelling approach and framework for integrating regional variation, nitrogen management, and lifecycle GHG accounting could inform UK biofuel or oilseed crop sustainability assessments.
Key measures
Lifecycle greenhouse gas emissions (likely CO₂-equivalents) from biodiesel production; nitrogen use efficiency; spatial variation by agroecological zone and cropping system
Outcomes reported
The study modelled lifecycle greenhouse gas emissions from biodiesel feedstock production (canola and soybeans) across different agroecological zones and nitrogen use efficiency scenarios. Spatially-resolved estimates of GHG mitigation potential were generated to inform biofuel crop expansion planning.
