Cost-effective mitigation of nitrogen pollution from global croplands

B. Gu, X. Zhang, et al.

This groundbreaking research by Baojing Gu and colleagues reveals that innovative measures can reduce nitrogen losses from cropland by 30–70% while boosting crop yields and efficiency. With an estimated societal benefit of 476 billion USD, this study proposes a nitrogen credit system to encourage these vital practices, showcasing the potential for significant environmental and economic impact.

Abstract
Cropland is a major source of global nitrogen pollution. This paper synthesizes 1,521 field observations to identify 11 key measures to reduce nitrogen losses by 30–70%, increase crop yield and nitrogen use efficiency, and generate a global societal benefit of 476 ± 123 billion USD, with net mitigation costs of only 19 ± 5 billion USD. A nitrogen credit system is proposed to incentivize the adoption of these measures.
