英文摘要 | When distributed equally, the total amount of food produced worldwide could sufficiently meet current global demand. Still, malnutrition in the form of nutrient deficiencies continues to prevail in both low- and high-income countries. At the same time, natural resource use for agriculture is reaching or exceeding environmental boundaries. By integrating a comprehensive micronutrient scoring method with data on agricultural water demand, this analysis aims to re-evaluate the global water-use efficiency of dietary nutrient production. A stronger reliance on more nutrient-dense foods could lead to higher water-use efficiencies, though dietary water footprints were likely to increase overall. With a more detailed focus on plant and animal foods, we find that most dietary protein sources show comparable water-use efficiencies, and thus can be drivers for agricultural water demand. Animal foods, besides having a unique nutrient profile, often do not compete directly with crops for the same water resources. However, a significant reduction in the demand for utilizable freshwater resources could be achieved by reducing the amount of feed crops in ruminant diets. |
