Effective nitrogen management requires science-based policy design and implementation. This session examines policy-relevant nitrogen monitoring and inventory systems, as well as integrated policy instruments linking agriculture, industry, and energy. Topics include nitrogen and sustainable development, holistic policy approaches, national action plans, communication challenges, and other relevant efforts aiming to bridge science, governance, and multi-level nitrogen management.
[10] Economic Aspects
Economic activities drive both the benefits and costs of nitrogen use. This session examines economic and behavioral dimensions of nitrogen management, including cost–benefit analyses, life cycle assessments, green finance (“nitro-finance”), labeling and nudging strategies, and the economics of organic and circular agriculture. It aims to clarify trade-offs and synergies between economic growth, environmental protection, and sustainable nitrogen utilization.
[11] Co-Creation, Communication, Culture, and Education
Addressing nitrogen challenges requires collaboration among scientists, policymakers, the private sector, civil society, farmer organizations and the general public. This session focuses on transdisciplinary approaches, stakeholder engagement, environmental education, citizen science, and communication strategies. It explores how culture, values, food traditions, and public awareness can foster sustainable nitrogen use. Innovative educational tools and indicators that encourage behavioral change and co-created solutions will be highlighted.
[12] Special Thematic Sessions
Special Thematic Sessions address cross-cutting and emerging topics beyond the main session categories, aligned with the conference theme “Sustainable Nitrogen Management for Future Generations.”

Can Nitrogen Be Managed Alone? Lessons from Multi-Nutrient Landscapes
Conveners: João Serra, José Mogollón, Luis Lassaletta, Alberto Sanz-Cobeña, Misuzu Asari
Nitrogen cannot be managed in isolation from other nutrient cycles. This session challenges the assumption that improving nitrogen use efficiency alone ensures sustainability, showing how interactions with phosphorus, carbon and hydrology affect environmental performance in agro-food systems. Drawing on empirical evidence, modelling and case studies across scales, we explore when a multi-nutrient perspective becomes necessary, and how more integrated approaches can better address trade-offs and support more grounded policy decisions.
