Impact/Purpose:
Nitrogen management is a critical issue facing the society today because of its indispensable need along with negative impacts that occur due to nitrogen losses to environment. In this work, product input-output tables are used to inform strategy for nitrogen management that can reduce the external impacts of nitrogen use.
Description:
Here we describe the development of nitrogen PIOTs for the midwestern US state of Illinois with large inputs of nitrogen from agriculture and industry. The PIOTs are used to analyze the relationship between regional economic activities and ecosystem services in order to identify activities that enhance or negatively impact ecosystem services. In addition, the effect of inter-region trade on ecosystem services is enumerated. Ultimately, this model identifies mitigation strategies for nitrogen and their relationship to ecosystem services. Along with informing specific ecosystem services decisions related to nitrogen, this work contributes to the development of more complete physical accounts which can be used together with economic IO data for economy-wide analyses. **This is a short version of the submitted abstract - see the attached file for the full abstract.
