How to increase nitrogen use efficiency
Lead 1: Jørgen Eriksen (Aarhus University, Denmark)
Lead 2: Alberto Sanz-Cobeña (Technical University of Madrid, Spain)
Lead 3: David Kanter (New York University, USA)
Session Chairs: Rasmus Einarsson, Claas Nendel, Guillermo Guardia, Gerline de Deyn, Jørgen Eriksen, Alberto Sanz-Cobena
Contributions to this session deal with measures to improve the amount of nitrogen retained in crops, both for human consumption and feed, as well as for other purposes. A wide range of scales and views are included, from physiological/genetic/molecular studies to farm, regional, national, and global nitrogen budgets.
Reducing nitrogen losses
Lead 1: Søren O. Petersen (Aarhus University, Denmark)
Lead 2: Iris Vogeler (Aarhus University, Denmark)
Lead 3: Mari Luz Cayuela (Consejo Superior de Investigaciones Científicas, Spain)
Session chairs: Sasha Hafner, Ana, Meijide, Reinhard Well, Kirsten Verburg, Shabtai Bittman, Christian Dold, Nick Hutchings, Diego Abalos, Klaus Buttebach-Bahl, Sharon Aarons, Barbara Amon, Søren O. Petersen, Iris Vogeler, Mari Luz Cayuela
From technological and management options to land use changes and landscape structures, contributions to this session tackle the reactive and nonreactive losses of nitrogen across the agri-food and land-use sectors.
Nitrogen recycling
Lead 1: Uffe Jørgensen (Aarhus University, Denmark)
Lead 2: Peter Sørensen (Aarhus University, Denmark)
Lead 3: Lorie Hamelin (National Research Institute for Agriculture, Food and Environment (INRAE), France)
Session chairs: see leads
This session aims to illuminate the role that the recovery and recycling of nitrogen within agriculture, landscapes and society can play for the transition from a fossil-fuel-based economy to a biocircular one.
Incentives for good nitrogen management
Lead 1: Brian Jacobsen (University of Copenhagen, Denmark)
Lead 2: Tommy Dalgaard (Aarhus University, Denmark)
Lead 3: Wilfried Winiwarter (International Institut for Applied Systems Analysis (IIASA), Austria)
Session chairs: see leads
This session will present and discuss different policy- and business-driven initiatives to reduce agricultural nitrogen pollution, and to understand the views from farmers, NGOs, and consumers.
Food systems
Lead 1: Luis Lassaletta (Technical University of Madrid, Spain)
Lead 2: José Mogollón (Leiden University, NL)
Lead 3: Ute Skiba (Centre for Ecology&Hydrology, UK)
Session chairs: Gilles Billen, Luis Lassaletta, José Mogollón, Ute Skiba
This session covers broad and integrated perspectives along the food chain from production to consumption (including dietary changes), encompassing processing, transport, and packaging.
Livestock in agricultural systems from a nitrogen perspective
Lead 2: Christian Friis Børsting (Aarhus University, Denmark)
Lead 3: Johanna Pedersen (Aarhus University, Denmark)
Session chairs: see leads
The livestock sector has altered nitrogen flows at an alarming pace, and therefore this session will explore scenarios and alternatives to understand how this sector may look like over the coming years.
