The promise of biotechnology in addressing current nutritional problems in developing countries

To meet the nutritional needs of a rapidly growing world population, which is likely to reach 8 billion by 2030, 50% more food grains with higher and more stable yields must be produced. Biofortification is considered the most effective way to increase micronutrient intakes. It is low cost and sustainable and does not require a change in eating habits or impose recurring costs. A research project to improve the iron and zinc content of rice was initiated at the International Rice Research Institute in 1992. Several experimental lines of rice with increased iron and zinc content have been produced. In another experiment rices with beta-carotene have been produced. Other experimental efforts aim at raising the micronutrient content in wheat, maize, cassava, sweet potatoes, and beans. Maize with improved amino acid balance is being grown in several African countries.
