Table 4. The annual percentage yield increases needed to produce the HHEP diet for the world population of 2050 without an increase in the amount of arable land.
| Food Groups | 9.8 Billion population by 2050 |
|---|---|
| Whole Grains | No increases needed* |
| Fruits & Vegetables | 8.72%/yr |
| Oils | No increases needed* |
| Protein | 3.27%/yr |
| Milk/dairy | 0.79%/yr |
| Sugar | No increases needed* |
* Since we are currently producing grains, oils & fats and sugars in excess of projected need, these categories can either be less intensively farmed or land could be taken out of production for these crops, thus reducing agriculture’s impact on ecosystem services.
