Nitrogen Session at Planet under Pressure
The International Nitrogen Initiative (INI), Global Partnership on Nutrient Management (GPNM) and the International Geosphere-Biosphere Programme (IGBP) organized a successful session on Nitrogen: too much of a good thing at the Planet under Pressure conference March 26 in London. About 150 - 200 people visited the session, which covered a scientific and policy context as well as showing the issues from a different regional perspective. The session was followed by a poster session later that day, which was visited by most of the 3000 visitors and included more than 30 posters. The sessions were organized by: Jan Willem Erisman, Louis Bolk Institute; Jim Galloway, University of Virginia; Mercedes Bustamante, Universidade de Brasilia; Eric Davidson, The Woods Hole Research Center; Lex Bouwman, Netherlands Environmental Assessment Institute
