Sustainable crop and animal production to help mitigate N2O emissions


Article on the way N2O emissions from agriculture can be tackled by reducing demand for, and consumption of, nitrogen inputs via diet modification and waste reduction, and/or through technologies applied at the field level.

Research Coordination Network on Reactive Nitrogen

The National Science Foundation (NSF) has funded a 5-year project, beginning March 2011, to create a network of researchers who specialize in a wide range of disciplines pertaining to excess nitrogen in the environment, including aquatic and terrestrial ecology, agronomy, atmospheric chemistry, groundwater dynamics, engineering, epidemiology, and economics. We propose to partner with Resource Media, which has created Nitrogen News as part of a project supported by the David and Lucile Packard Foundation.


Future Collaboration with Canada

Our Canadian colleagues have been conducting national N assessment activities under the umbrella of Canada’s participation in the UNECE Task Force on Reactive N (TFRN). The US also participates in TFRN. Although we have no joint projects at this moment, we aspire to coordinate US and Canadian N assessment activities and interests within the North American Center for the INI.


A National Nitrogen Assessment for the USA

The Office of Science and Technology Policy (OSTP) is tasked with producing a National Climate Assessment (NCA) in 2013. Due to the multiple interactions of nitrogen with climate change mitigation, adaptation, and impacts, we were invited by OSTP to submit a technical report that assesses nitrogen-interactions in the USA. The report was submitted on March 1, 2012, and is available for download here. Each of the seven chapters of the report has gone through peer review and will soon be available here and on the web site for the journal, Biogeochemistry.


The Nitrogen Footprint calculator (N-Print)

Jim Galloway (Univ. of Virginia) and colleagues have developed this tool to help communicate to the public the role that their actions have on the nitrogen cycle and the environment. Through this tool, we aim to educate people about nitrogen, how their lifestyles impact the nitrogen cycle, and how they can reduce their nitrogen footprint. The tool will be upgraded as our underlying scientific knowledge improves. You can view the N-Calculator at the following website:
