N2 - Agro-ecosystems for integrated food, fodder, and biomass production can contributeto achieving European Union goals to increase renewable energy sources and reduce greenhousegas emissions. The study objective was to evaluate the productivity and economic returns from acombined food and energy (CFE) system compared to sole winter wheat and sole short rotationwoody crop (SRWC) production. Two excel-based models viz. Yield-SAFE and Farm-SAFE, wereused to simulate agronomic productivity and economic assessment respectively. Yield-SAFE wascalibrated and validated with measured data from CFE from 1996–2016. When compared overtemporal scale of 21 years, CFE systems with 150–200 m alley width had the highest net present value(NPV) followed by 100 m, 50 m, sole winter wheat and sole SRWC, indicating higher profitability ofCFE systems. Sensitivity analysis of NPV with 10% yield fluctuations, and with 0–10% discountrate, demonstrated that CFE systems was more profitable than sole crops, indicating higher resiliencein CFE systems. LER in CFE ranged from 1.14–1.34 indicative of higher productivity of CFE systemscompared to component monocultures. Hence, the study has demonstrated that the productivity andthe economic viability of CFE systems, were higher than sole crops, for informed decision makingby farm managers and policy makers to contribute to renewable energy biomass production and tomitigate the impending adverse climate change effects on agricultural production.
