El cambio climático podría hacer que el arroz sea menos nutritivo

Inglés

Niveles de dióxido de carbono alterarán el contenido de proteína, micronutrientes, y vitaminas de granos de arroz con potenciales consecuencias para los países pobres dependientes de arroz este siglo

600 million people could be affected as climate change decreases the levels of several nutrients in rice, according to a new paper. The paper estimated changes in rice nutrient content using experiments where rice (of several different cultivars) was grown under conditions of enriched CO2. At the higher CO2 levels, the following average decreases in nutrient levels were found compared to rice grown under ambient CO2: 10% for protein; 8% for iron; 5% for zinc; 17% for vitamin B1; 17% for vitamin B2; 13% for vitamin B5; 30% for vitamin B9. In contrast, vitamin E levels were 14% higher under elevated CO2levels.
