1) Business-As-Usual (BAU) |
1A
2050 PUE at current
level;
P fertilizer to total inputs (fertilizer + manure)
ratio = 100%, and total inputs = projected P inputs
|
1B
2050 PUE at current
level;
P fertilizer to total inputs (fertilizer + manure)
ratio = current level, and total inputs = projected P inputs
|
1C
2050 PUE at current
level;
P fertilizer to total inputs (fertilizer + manure)
ratio = current level, and total inputs = projected P inputs - P
residual accumulated since 1961
|
2) Moderate-Policy-Ambition (MPA) |
2A
2050 PUE linearly improved to median
level;
P fertilizer to total inputs (fertilizer + manure)
ratio = 100%, and total inputs = projected P inputs
|
2B
2050 PUE linearly improved to median
level;
P fertilizer to total inputs (fertilizer + manure)
ratio = current level, and total inputs = projected P inputs
|
2C
2050 PUE linearly improved to median
level;
P fertilizer to total inputs (fertilizer + manure)
ratio = current level, and total inputs = projected P inputs - P
residual accumulated since 1961
|
3) High-Policy-Ambition (HPA) |
3A
2050 PUE linearly improved to
75th percentile level;
P fertilizer to
total inputs (fertilizer + manure) ratio = 100%, and total inputs =
projected P inputs
|
3B
2050 PUE
linearly improved to 75th percentile
level;
P fertilizer to total inputs (fertilizer + manure)
ratio = current level, and total inputs = projected P inputs
|
3C
2050 PUE linearly improved to
75th percentile level;
P fertilizer to
total inputs (fertilizer + manure) ratio = current level, and total
inputs = projected P inputs - P residual accumulated since
1961
