Up to half a million children around the world are going blind every year due to a lack of Vitamin A in their diets. According to the World Health Organization, Vitamin A deficiency, — which afflicts 250 million children worldwide — is the leading cause of preventable blindness in children and increases the risk of disease and death from severe infections. It is a public health problem in more than half the world’s nations, especially in Africa and Southeast Asia, affecting young children and pregnant women in low-income countries the hardest.
In Kenya, scientists are tackling this problem by developing biofortified sorghum, a staple crop that has been genetically modified to contain higher levels of Vitamin A. More than 300 million sub-Saharan Africans depend on sorghum as their primary calorie source. Its drought- and heat-tolerant properties mean it is a vital crop in drought-prone countries, where irrigation is not always accessible or affordable. Improving the nutritional level of staple crops can provide both food and nutritional security. See more
