The Nitrogen Reduction Challenge is open to all ventures globally that are developing technical, market-based solutions to combat hypoxia, a deadly deficiency of oxygen in water created by the excessive growth of phytoplankton. This international competition that will award $1 million to the entrepreneur, researcher, or inventor with the best plan to reduce the amount of nutrients entering the world’s lakes, rivers, and oceans through storm water runoff and ultimately reduce the hypoxic zone in the Gulf of Mexico.



Team registration is closed.



Grand Prize $1,000,000



The Problem

Throughout the world, increasingly fragile coastal and inland lake ecosystems face a common and persistent threat; “dead zones” caused by hypoxia continue to challenge the integrity and productivity of environments that are home to a diverse biota and highly valued natural resources. Dead zones result from excess nutrients flowing from rivers to near-shore areas. Though hypoxia is often thought of as a challenge particular to the northern Gulf of Mexico, as the map above shows, dead zones are a problem of global proportions.

Hypoxia occurs when the oxygen required to support life becomes depleted, which can result in severe impairment of near-shore fisheries. Consequently, dead zones can also destabilize the businesses, families and communities that are sustained by fisheries. Further, nutrient enrichment can jeopardize the future of estuaries and coastal wetlands that depend on freshwater and sediment delivery for stability and persistence. In short, clean water is critical to the ecological, cultural and economic well-being of Louisiana, the nation and the world.

Addressing hypoxia is a grand challenge because solutions must meet a suite of simultaneous and sometimes conflicting needs – from protecting water resources and near-shore ecosystems to ensuring the capacity and vitality of agricultural productivity.

The Prize

The $1 million prize will be awarded to the team or individual that creates a testable and scaled operating model that meets the challenge’s goals of creating a significant new way to address hypoxia in an efficient, cost effective and scalable way.

We expect the winning innovation will succeed as a market driven solution and the wining team, as well as all competitors, will reap many benefits above and beyond the grand prize.

Why Tulane?

Tulane University has always been a nationally recognized leader in fostering a culture of public service and civic engagement. After Hurricane Katrina in 2005 Tulane’s mission expanded, making community engagement a central part of all of its education and research activities.

At Tulane we recognized how much the community and our students, faculty and staff could learn from one another if we worked together to create positive change. Through social entrepreneurship and innovation, Tulane and its community partners are creating a new New Orleans and building a better world.


Be a part of the solution. Your donation of any size will support our efforts to combat hypoxia, and improve the ecological, cultural, and economic well-being of Louisiana, the nation, and the world. Help us fuel innovation and achieve our ambitious goal by supporting the competition. Together we can create positive change that improves lives for years to come.
