Table 1. Mean macronutrient availability in baseline and potential waste and yield scenarios in 2030.
| Scenario | Mean caloric availability; kcalpppd (percentage of population below average requirement) | Mean digestible protein availability; gpppd (percentage of population below average requirement) | Mean fat availability; gpppd (percentage of population below average requirement) |
|---|---|---|---|
| Recommended Daily Intake (RDA) | 2269 | 50 | |
| 2011 Baseline Scenario | 2039 (66%) | 48 (56%) | 49 |
| 2030 Baseline Scenario | 1665 (89%) | 39 (83%) | 40 |
| Scenario 1 (halving food losses) |
1754 (84%) | 42 (75%) | 43 |
| Scenario 2 (achieving 50% AY) |
1675 (88%) | 40 (81%) | 41 |
| Scenario 3 (achieving 75% AY) |
1831 (80%) | 42 (75%) | 46 |
Average macronutrient availability in baseline and projected scenarios to 2030, relative to average population requirements. Scenario 1 is based on the assumption of halving food losses across the supply chain; and scenarios 2 and 3 achieving 50% and 75% of attainable yields across all crops, respectively. The percentage of the population which would fall below average requirements based on dietary distribution data is reported in brackets.
