SUSTAINABLE & HEALTHY COMMUNITIES RESEARCH PROGRAM

Challenge

• Increases in reactive N have lead to benefits but high costs for ecosystems and human health.

• Need approaches to reduce N inputs in the most economically efficient, socially acceptable, and environmentally sound way. 

• How do we help get there, in response to local, regional and national issues?

SUSTAINABLE & HEALTHY COMMUNITIES RESEARCH PROGRAM

Research

• Air standards and programs– N input and CC impacts on biodiversity and ES

• Water quality – OW and states ‐ Regional– Link nutrient load/source to economic impacts

• Cross‐media ‐ Communities – Application of nutrient loading, management tools, scenarios and dynamic modeling 

– Tools to help determine how and where to reduce N inputs

Results: Interactive effects of climate change and N on ecosystems and services

1. National analysis of N deposition impacts on plant communities.

2. Regional N deposition and climate change effects on forest composition and ecosystem services.

3. Online tool for stakeholders to explore ecosystem vulnerability to nitrogen deposition.

Costs of nitrogen pollution

US values  Compton et al. (2011 EL)

EU low and high values are from EU N Assessment  Van Grinsven et al. (2013 ES&T)

Many gaps exist  e.g. HABs, N and forests

Science directions in SHC‐N 

•Response functions – for terrestrial, aquatic and drinking water impacts on ecosystem services

•Connect N reductions in N loads to benefits•Research at several scales, cooperation from many agencies to address wicked problem
