The Mississippi River/Gulf of Mexico Hypoxia Task Force Action Plan calls for the reduction of excessive nutrients to the Gulf of Mexico. As part of this overall effort, states are developing Nutrient Reduction Strategies. The individual state strategies need to outline how states will reduce nutrient impairments within their jurisdiction, improve the quality of life for citizens, and contribute to reducing the size of the hypoxia zone in the Gulf of Mexico. Each state’s Nutrient Reduction Strategy needs to answer four basic questions:
- What nutrient load reductions are achievable?
- How will these reductions be achieved?
- What are the implementation schedule and corresponding milestones for this effort?
- What is the value to each stakeholder of these reduction efforts?
The state strategies are to cover all major sources within the states.
Agriculture has been identified as the largest source of nutrients impacting the Gulf. The diversity of agriculture throughout the Upper Mississippi and Ohio River basins and the range of agricultural intensity between states requires that each state develop a state-specific plan to address agriculture.
These webcasts are an extension of a June 2011 workshop intended to help states in the basins develop the agricultural component for their State Nutrient Reduction Strategies.
