Nitrogen is essential for plant growth and plays a critical role in global food production through its use in synthetic fertilizers. However, inefficient or excessive nitrogen application has become a major environmental concern. It contributes to greenhouse gas emissions, particularly nitrous oxide (N₂O), as well as water pollution and soil degradation. Balancing fertilizer use to ensure food security while reducing environmental and climate impacts is vital.
Improving nitrogen use efficiency (NUE) — applying the right amount of fertilizer is key to increasing crop productivity and minimizing greenhouse gas emissions and other ecological risks. Spatially explicit global dataset on nitrogen input, output and NUE helps understand current nitrogen management systems as well as design and development of tailored nitrogen management practices for address food, fertilizer and climate crisis.
The AgroNutrient Explorer is a centralized, data-driven platform designed to integrate global data on nitrogen inputs, outputs, and NUE. It will support:
- Researchers with comprehensive datasets for modeling and analysis.
- Policymakers in designing region-specific fertilizer and climate policies.
- Farmers and advisors in making informed decisions on nutrient management.
This initiative contributes to global goals for food security, sustainable agriculture, and climate resilience, and directly supports several United Nations Sustainable Development Goals including zero hunger, responsible consumption, climate action, and protecting terrestrial ecosystems.
