trans4num: Advancing Nature-Based Solutions for Sustainable Nutrient Management

trans4num is a four-year EU-China collaboration funded under the Horizon Europe Zero Pollution call, advancing nature-based solutions (NBS) for sustainable nutrient management in agriculture across Europe and China. The project focuses on bio-based fertilisers, sustainable crop rotation, integrated pest management, and reduced chemical fertiliser use. It targets socio-ecological transformation in intensive farming systems through innovative NBS practices and transformative pathways. The project spans seven sites—four in Europe and three in China—applying a multi-level, multi-actor approach. Key activities include system analysis, NBS inventory, nutrient flow optimization, scenario development, and pathway design. Expected outcomes include a decision support system (DSS) for nutrient budgeting, improved nutrient management scenarios, and stakeholder engagement across all levels. The consortium includes leading institutions from Germany, Denmark, the Netherlands, the UK, Hungary, and China. The project promotes international cooperation, market opportunities for NBS, and long-term sustainability in agriculture. For updates, visit www.trans4num.eu/en.
