Summary
Biofuel production in the United States presents environmental nutrient management challenges. Integrated modeling shows agricultural changes in the Upper Mississippi River Basin may not align with broad stakeholder interests.
Area of Science:
- Environmental Science
- Agricultural Science
- Systems Modeling
Background:
- Biofuel feedstock production is a growing environmental concern in the US.
- Addressing stakeholder interests requires a multi-scale, multimedia systems modeling approach.
Purpose of the Study:
- To explore environmental consequences of increased biofuel production from maize grain and stover.
- To simulate yield and cropland reallocation for 20 crops across the continental US.
Main Methods:
- Integrated energy and agricultural markets models.
- Hybrid process-based agricultural production model.
- 12km grid resolution simulations for the continental US.
Main Results:
- Projections of yield and cropland reallocation for 20 agricultural crops.
- Analysis of agricultural changes within the Upper Mississippi River Basin (UMRB).
- Comparison of UMRB results with previous studies.
Conclusions:
- Agricultural and crop science are crucial for plausible yield increase estimates.
- The UMRB faces significant agricultural changes, but these may not serve all stakeholders.
- A systems modeling approach is vital for understanding biofuel impacts.
