The Nutrient Reduction Decision Support Toolbox is intended for use by state and local agencies and other organizations interested in reducing nutrients (nitrogen and phosphorus) and other pollutants to our waterbodies.  The toolbox originated from the Gulf of Mexico Alliance (GOMA) Nutrient Reduction Priority Issue Team (PIT) and its initiatives to reduce the size of the hypoxic zone in the Gulf of Mexico as well as occurrences of hypoxic events across Gulf of Mexico coastal and estuarine waters.  Nutrient reduction efforts must be made throughout the five Gulf states, as well as the states within the upper and lower Mississippi and Ohio River Basins to be successful at reducing Gulf hypoxia.  

The toolbox is based on a comprehensive and holistic framework for nutrient reduction developed through the collaborative interaction of local, state, and federal agencies; non-governmental organizations; agricultural producers; private businesses; and academic institutions.  

Each of the drawers in the toolbox represents one of the 10 key decision elements that are essential to reducing nutrients and their impacts within our waters.

To get started, use the menu to the left, or jump to the navigable toolbox graphic, and select any drawer to see the information available on that topic.

The toolbox is intended to be an electronic repository for links to information related to each of the decision elements needed for a comprehensive approach to reducing nutrients for aquatic ecosystems.

Toolbox users will use this information to make decisions, either implicitly or explicitly, on each of these elements. The toolbox is intended to provide valuable information to assist in making these decisions.
