Biobased energy, particularly corn starch-based ethanol and other liquid renewable fuels, are a major element of federal and state energy policies in the United States. These policies are motivated by energy security and climate change mitigation objectives, but corn ethanol does not substantially reduce greenhouse gas emissions when compared to petroleum-based fuels. Corn production also imposes substantial negative externalities (e.g., nitrogen leaching, higher food prices, water scarcity…

Corn-based ethanol production compromises goal of reducing nitrogen export by the Mississippi River

Examination of extreme mitigation options shows that expanding corn-based ethanol production would make the already difficult challenges of reducing nitrogen export to the Gulf of Mexico and the extent of hypoxia practically impossible without large shifts in food production and agricultural management.

Evaluating Alternative Options for Managing Nitrogen Losses from Corn Production

Widespread and intensive agricultural activity, particularly corn production, has resulted in large amounts of nitrogen (N) loading to surface and groundwater1,2. Elevated N levels in streams and

Cropland expansion outpaces agricultural and biofuel policies in the United States

Cultivation of corn and soybeans in the United States reached record high levels following the biofuels boom of the late 2000s. Debate exists about whether the expansion of these crops caused

Multi-scale Analysis of Nitrogen Loss Mitigation in the US Corn Belt

Reducing the size of the hypoxic zone in the Gulf of Mexico has proven to be a challenging task. A variety of mitigation options have been proposed, each likely to produce markedly different patterns

Ethanol Can Contribute to Energy and Environmental Goals

It is already clear that large-scale use of ethanol for fuel will almost certainly require cellulosic technology and new metrics that measure specific resource inputs are developed, but further research into environmental metrics is needed.

Fine-Scale Analysis of the Energy−Land−Water Nexus: Nitrate Leaching Implications of Biomass Cofiring in the Midwestern United States

As scientists seek to better understand the linkages between energy, water, and land systems, they confront a critical question of scale for their analysis. Many studies exploring this nexus restrict

Productivity Growth and Convergence in Crop, Ruminant and Non-Ruminant Production: Measurement and Forecasts

There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international

Evaluation of a Process-Based Agro-Ecosystem Model (Agro-IBIS) across the U.S. Corn Belt: Simulations of the Interannual Variability in Maize Yield

Abstract A process-based terrestrial ecosystem model, Agro-IBIS, was used to simulate maize yield in a 13-state region of the U.S. Corn Belt from 1958 to 1994 across a 0.5° terrestrial grid. For
