The Economics of Dead Zones: Linking Externalities from the Land to their Consequences in the Sea, October 2012,

The purpose of this review and analysis is to provide a basic understanding of the issues related to worldwide hypoxic zones and the range of economic questions sorely in need of answers. We begin by describing the causes and extent of hypoxic zones worldwide, followed by a review of the evidence concerning ecological effects of the condition and impacts on ecosystem services. We describe what is known about abatement options and cost effective policy design before turning to an analysis of the large, seasonally recurring hypoxic zone in the Gulf of Mexico. We advance the understanding of this major ecological issue by estimating the relationship between pollutants (nutrients) and the areal extent of the hypoxic zone. This “production function” relationship suggests that both instantaneous and legacy contributions of nutrients contribute to annual predictions of the size of the zone, highlighting concerns that ecologists have raised about lags in the recovery of the system and affirms the importance of multiple nutrients as target pollutants. We conclude with a discussion of critical research needs to provide input to policy formation.

Special Events Planning, 2010

The Iowa Department of Transportation (Iowa DOT) Special Events Planning (SEP) document is a collection of Special Event Management Strategic Plans for individual events throughout the state of Iowa. The development of the SEP document focused on improving travel, safety and efficiency to and from Iowa’s largest traffic generating events through the review of event specific traffic management components. Initially, three events were selected from the state of Iowa for inclusion in the SEP document. As Strategic Plans are developed for additional events, those events will be included in the SEP document. The three initial events that are included in this SEP are: • Iowa State Fair; • Iowa State University Home Football Games; • University of Iowa Home Football Games. The Strategic Plan for each event documents existing transportation conditions for the event based on field observations, highlights positive existing practices and issues for consideration, and provides recommendations, both short and long term, to be considered as potential improvements to event operations. The objective of each Strategic Plan was, at a high-level, to analyze traffic and pedestrian flow at each event and to work with event staff, agencies and others in developing roadway, operations and safety improvements where appropriate. The SEP document is intended to be a “living” document with updates to the Strategic Plans occurring as warranted and additional Strategic Plans being incorporated for other events. The enacting of recommendations contained within each Strategic Plan is not a mandate for the responsible agency for a particular event. The Strategic Plans are intended to provide a basis for discussion between the Iowa DOT and agencies involved in the planning and implementation of transportation operations for large traffic events regarding opportunities to improve the event patron’s experience.
