A vast land mass across the globe, both coastal as well as terrestrial, has been marginalized because of excessive salinity and alkalinity. The transgenic plants were found to be tolerant to higher concentrations of salt. A concentration and most national authorities rely on expensive and complicated supplementation programs to address the problem. Such yellow, or golden, rice may be a useful tool to help treat the problem of vitamin A deficiency in young children living in the tropics. Iron fortification is required because cereal grains are deficient in essential micro-nutrients such as iron.
Iron deficiency causes anemia in pregnant women and young children.
About 400 million women of child-bearing age suffer as a result, and they are more prone to stillborn or underweight children and to mortality at childbirth. Reduced Environmental Impact Water availability and efficient usage have become global issues. Low tillage systems have been used for many years in traditional communities. Applications in more developed countries show that GM technology offers a useful tool for the introduction of root disease resistance for conditions of reduced tillage. However, a careful cost-benefit analysis would be needed to ensure that maximum advantage is achieved.
