Fig. 5: Relative changes in total Nr input of food production and consumption in Inner Mongolia, driven by population growth, number of reared livestock and poultry animals changes, dietary changes, and crop cultivation area changes, relative to 2000–2020.
From: Nitrogen flow in food production and consumption system of Inner Mongolia from 2000 to 2020
S1: population size, crop cultivation area, number of reared livestock and poultry animals, and dietary structure are maintained at the 2000 level. S2: changes in the dietary structure based on S1. S3: changes in the number of reared livestock and poultry animals based on S2. S4: changes in the population size based on S3. S5: actual situation: changes in the crop cultivation area based on S4. Error bars represent the standard deviation of the mean.
