Sustai-N-able
Towards Sustainable Nitrogen Use Connecting Human Society and Nature

Our nitrogen (N) use provides great benefits as fertilizer for food production and materials for industrial production. However, the production and consumption of food, goods, and energy induce a huge amount of reactive N (N compounds other than inert and harmless dinitrogen) loss to the environment that threatens human and ecosystem health through various N pollution. This is the N issue, i.e., a tradeoff between benefits of our N use and threats of N pollution accompanied. The Sustai-N-able project conducts inter- and trans-disciplinary research towards sustainable nitrogen use for future generations.
