Tackling nutrient pollution in the Gulf of Mexico is a big job, requiring coordination between dozens of states whose waters flow into the Mississippi. Although a 2011 U.S. Environmental Protection Agency memo set a framework for each state to reduce its nutrient load, it was up to the states to set their own policies in motion.
More than a decade on, critics have questioned the effectiveness of state nutrient reduction strategies, noting the still-massive hypoxic dead zones in the Gulf. In a new University of Illinois-led study, social scientists looked at the process states took to develop and implement their strategies, identifying key strengths and challenges that can inform other large-scale cooperative efforts.
