Special Session
The generation and use of reactive nitrogen leads to a suite of both beneficial and adverse effects. Examples of beneficial effects are increased productivity of land for food and fibers, and for sequestration of CO2. Examples of adverse effects are pollution of air and water which impact both biodiversity and human health, and increased emission of greenhouse gasses. In recent decades great progress has been made in quantifying these effects and increasingly nitrogen management and policies are implemented to reduce these negative effects. In view of the multiple sources, forms and impact pathways of nitrogen, such policies need to be integrated and holistic. This to prevent trade-offs and to promote synergies, to ultimately finding a balance between benefits and costs of nitrogen for society. In 2021, both the EU and the UN have set ambitious targets to halve nitrogen waste both to reduce pollution and save nitrogen as a valuable resource.
Economic valuation and cost-benefit analysis (CBA) are increasingly used to design and evaluate integrated nitrogen management and policies.
The aims of this special session are:

Dr. Bonnie Keeler is a McKnight Presidential Fellow and Charles M. Denny Chair in Science, Technology, and Environmental Policy at the University of Minnesota’s Humphrey School of Public Affairs. Keeler has expertise in integrated assessment modeling, benefit cost analysis, water and agriculture policy, non-market valuation, and urban green infrastructure. She integrates quantitative modeling, economic valuation, and spatial analyses with qualitative and participatory approaches to capture multiple perspectives on complex social and environmental problems. Current projects include investigating the effects of climate change on water resources, environmental justice implications of nature-based solutions, governance dimensions of state and tribal groundwater management, and quantification of the social costs of water pollution.
Keeler is the Co-Director of the CREATE Initiative, a community-engaged research project that aims to leverage the resources of the research university in service to the needs and priorities of environmental justice organizations in urban watersheds. Keeler is a Co-Investigator of the Minneapolis-St.Paul Urban Long-Term Ecological Research site where she oversees research on contemporary and historical dynamics of green infrastructure investments and wealth distribution. Keeler also directs the Beyond the Academy network - a coalition of university leaders seeking to reform academic models to promote actionable, engaged scholarship on sustainability.

Hans van Grinsven is Program Manager/Senior Researcher at the Department of Water, Agriculture and Food at Netherlands Environmental Assessment Agency (PBL).
His assessment work at PBL and publications cover current practices in agriculture and effects on the environment and options for more efficient and sustainable agriculture and food production in the Netherlands, the EU and globally. Hans works at the science-policy interface on nutrient policies and management, integrated nitrogen assessments and, since 2010, on cost-benefit assessments. Increasingly options go beyond “good practices” and research moves to design and evaluation of transitions towards more nature-inclusive, climate neutral agro-food-systems.
Hans currently is a coordinator and principal investigator for the Ïnternational Nitrogen Management System project (INMS 2017-2022) funded by the Global Environment Facility (GEF) through the United Nations Environment Programme (UNEP) and was a coordinator and editor of the European Nitrogen Assessment. He is a member of the Scientific Committee on Nutrient Management Policy (CDM) for the Dutch Ministry of Agriculture
Hans holds an MSc (1982; soil chemistry and physics) and PhD (1988; soil acidification) from Wageningen University.

In addition to oral communications and posters presentations
The Organizing Committee aims to minimize the environmental impacts of the workshop and both N and C footprints will be calculated afterwards.
We encourage an "in-person" attendance but facilitating a remote connection to key activities during the workshop. Seeing how volatile are these times, all scenarios should be considered now, even a new delay if the sanitary situation does not allow a minimum in-person attendance.
