  1. World Resources Institute AWAKENING THE DEAD ZONE An Investment for Agriculture, Water Quality and Climate Suzie Greenhalgh & Amanda Sauer

  2. World Resources Institute Hypoxia: What is it? What causes It? The Dead Zone • Seasonally oxygen depleted zone in the Gulf of Mexico • Mobile aquatic species leave the area • Those that can’t leave die or are weakened Primary Cause • Nitrogen from the Mississippi River Basin

  3. World Resources Institute Hypoxia: The Growing Problem Setting the scene

  4. World Resources Institute Sources of Nitrogen? Setting the scene

  5. World Resources Institute Where does the nitrogen come from? Source: USGS, 2000 Setting the scene

  6. World Resources Institute WRI Policy Research • Agricultural Policy Analysis • Fertilizer Tax on Nitrogen • Extension of CRP • Conservation Tillage Subsidy • GHG Trading • Nutrient Trading • Nutrient Trading with GHG Payments

  7. World Resources Institute Nitrogen delivered to the Gulf Setting the scene

  8. World Resources Institute Farm Income Setting the scene

  9. World Resources Institute Greenhouse Gas Emissions Setting the scene

  10. World Resources Institute Nitrogen Lost to Waterways Setting the scene

  11. World Resources Institute Phosphorus Lost to Waterways Setting the scene

  12. World Resources Institute Soil Erosion Setting the scene

  13. World Resources Institute Cost-Effectiveness Setting the scene

  14. World Resources Institute Regional Impacts Setting the scene

  15. World Resources Institute Regional Impacts Setting the scene

  16. World Resources Institute WRI Findings Findings • Considering nitrogen delivery to the Gulf is important • Nutrient trading is the most cost-effective solution • Co-benefits are important

  17. World Resources Institute WRI Recommendations Recommendations • Establish and implement a N cap for Mississippi River Basin • Promote nutrient trading programs • Develop a coordinated and collaborative approach to watershed planning • Establish coordinated monitoring strategies

  18. World Resources Institute WRI Recommendations Recommendations • Farm conservation spending should be targeted • Need to explore other opportunities to reduce GHG emissions • Develop strategy to address a suite of environmental problems NOT individual problems
