WHAT:

The world's leading nitrogen scientists will discuss the launch of the Global Nitrogen Assessment to provide policymakers with neutral, consensus-based science on the consequences of increased global nitrogen use. These experts hope to spur coordinated action across scientific and policy spheres to prevent climate, food security, and public health impacts. The long-term goal is to increase awareness of nitrogen pollution and provide guidance to policymakers, similar to the climate change information the Intergovernmental Panel on Climate Change (IPCC) provides.

WHO:

The Global Nitrogen Assessment is a project of the International Nitrogen Initiative, and supported by the Scientific Council on Problems in the Environment (SCOPE), the International Geosphere-Biosphere Program, and the David and Lucile Packard Foundation.

Teleconference participants include:

• James N. Galloway, Professor of Environmental Sciences, University of Virginia
• Cheryl A. Palm, Senior Research Scientist, Columbia University's Earth Institute
• Phil Robertson, Professor of Ecosystem Science, Michigan State University
• Alan Townsend, Professor of Ecology and Evolutionary Biology, University of Colorado, Boulder
• Dan Morgan, former Washington Post reporter and current German Marshall Fund fellow (moderator)

WHY:

Reactive nitrogen is essential to modern life, from the ability to grow food to the production of energy. Yet its benefits and problems are not evenly distributed.

Nitrogen-starved regions in Africa suffer from poor crop yields and malnutrition, while in the U.S., Europe and Asia, most nitrogen is released through chemical fertilizer use. Other sources of nitrogen pollution include inadequate sewage treatment, animal manure and smokestack and tailpipe emissions.

Reactive nitrogen contributes to ozone layer depletion, smog, acidification of soils and water supplies, climate change, water pollution, coastal “dead zones,” and human health problems. Growing demand for corn for biofuels and other uses continues to accelerate nitrogen pollution.

Experts have identified many policy and technology solutions that can be applied now, from using chemical fertilizer more precisely to increasing fuel efficiency and manure management and improving sewage treatment.
