Climate change will make rice less nutritious

RICE is the primary food source for more than 3 billion people around the world. Many are unable to afford a diverse and nutritious diet that includes complete protein, grains, fruits and vegetables. They rely heavily on more affordable cereal crops, including rice, for most of their calories. My research focuses on health risks associated with climate variability and change. In a recently published study, I worked with scientists from China, Japan, Australia and the United States to assess how the rising carbon dioxide concentrations that are fueling climate change could alter the nutritional value of rice. We conducted field studies in Asia for multiple genetically diverse rice lines, analysing how rising concentrations of carbon dioxide in the atmosphere altered levels of protein, micronutrients and B vitamins.

These findings also support research from other field studies showing rice grown under such conditions contains less protein, iron and zinc, which are important in fetal and early child development. These changes could have a disproportionate impact on maternal and child health in the poorest rice-dependent countries, including Bangladesh and Cambodia.

To simulate higher atmospheric CO2 concentrations, we used Free-Air CO2 Enrichment, which blows CO2 over fields to maintain concentrations that are expected later in the century....
