"Evaluating Alternative Options for Managing Nitrogen Losses from US Corn Production " by Liu, Jing, Laura Bowling, Christopher Kucharik, Sadia Jame, Uris Lantz Baldos, Larissa Jarvis, Navin Ramankutty and Thomas Hertel Abstract Mitigating the Hypoxia problem in the Gulf of Mexico has proven to be a challenging task. A variety of abatement options have been proposed, each likely to produce markedly different patterns of abatement with widely varying consequences for the economy. The general consensus is that no single measure alone is sufficient to achieve EPA Task Force goal for reducing the Gulf hypoxic zone and it appears that a combination of management practices must be combined. However, absent a highly resolved, multi-scale framework for assessing these policy combinations, it has been unclear what pattern of mitigation is likely to emerge from different policies and what the consequences would be for land use, food prices and farm returns. We address this research gap by utilizing a novel, multi-scale framework for evaluating alternative Nitrogen loss management policies in the Mississippi River Basin. This combines fine-scale agro-ecosystem responses with domestic and international market and price linkages. We find that wetland restoration combined with improved nitorgen use efficiency, along with a leaching charge could reduce the Mississippi River nitrogen load by 32\% while only modestly increasing the corn prices. This study underscores the value of fine-resolution analysis and the potential of combined economic and ecological instruments in tackling non point source nitrate pollution. |
