Exploring the instability in the food security due to nitrogen fertilizer regulatory policy

The nitrogen regulatory policy (NRP) solution is introduced as a mitigation meas- ure against environmental nitrogen losses and keeps food production in the Safe Operating Space of the Nitrogen Planetary Boundary. Meanwhile, scientific re- search shows that steps taken to reduce environmental harm can increase the un- predictability of calorie production from crops. This study sought to investigate the impact of NRP solutions on the level of risk of accessibility to calorie sources from...
