What is Nitrogen?
Reactive nitrogen is all forms of nitrogen except the unreactive N2
in the atmosphere. Reactive nitrogen is
created by natural processes, but its creation is now dominated by anthropogenic activities.
Humans make more reactive nitrogen than nature, largely through the production of synthetic fertilizers
and the combustion of fossil fuels
Reactive nitrogen has important benefits and
many unintended consequences.
Once in the environment, reactive nitrogen contributes to a
cascade of negative impacts to human and ecosystem health.
Understanding and managing sources of
reactive nitrogen will reduce these negative impacts.
What is a “Nitrogen Footprint?”
❖ How is Nitrogen Anthropogenically Produced?
➢ Combustion of fuels for electricity and transportation
➢ Cultivation of legumes w/ biological nitrogen fixation
➢ Production to synthetic fertilizers
Nitrogen Footprint Project ❖ Measuring sectors of a University
➢ Food Consumption and Production
➢ Research Animals
❖ Data input into Nitrogen Tool
❖ Analysis of different sectors impacts
❖ How can we reduce our impact?
➢ Created by University of Virginia
➢ Completed by 7 universities so far
➢ UH Manoa invited to be in the next cohort
Nitrogen and Carbon
Blue w/ white stripes - Carbon
Green shading - Overlap
What makes the UHM N-Footprint Project unique?
❖ Difference from other Universities
➢ Geographical Isolation
➢ Transportation Factor
➢ Food Dependability
❖ Unique data
❖ Hawaiʻi’s perspective
❖ Publishing in scientific journals*
❖ Invited to the N-Footprint conference at
the University of Virginia
*1 paper published and 3 papers just accepted in Sustainability: The Journal of Record, presentations at AASHE
Next steps for the
UH Nitrogen Footprint Project
❖ Contact officials of sectors for data information
❖ Collection and conversion of data, if needed
❖ Input of data into nitrogen tool
❖ Analysis of data
❖ Reduction scenarios
❖ Promotion of existent projects
❖ Implementation of best reduction scenarios
❖ Follow up data collection and analysis
❖ Promotion of project for other UH-system campuses
