GM crops and food
As the world population continues to grow and
more people need food, it becomes necessary to
increase food production. This can either be
though the clearing of new land for agriculture,
or by increasing yield of the crops on the same
amount or less land. The first generation of
GMO technology has been directed at reducing
the risks of various threats to crop yields such as
insect attack and virus infection. Scientists have
been adding genes to crop plants to give benefits
to farmers (Viljoen et al, 2006). Four GM
crops are cultivated in South Africa: insectresistant
cotton (since 1997), insect-resistant
maize (since 1998), herbicide-tolerant cotton
(since 2000) and herbicide-tolerant soybeans
(since 2001) (Department of Agriculture, 2005).
(Herbicides are chemical products used to
destroy weeds, but not the crop plants.)
In 2004, it was estimated that GM crops
accounted for 24% of yellow maize, 10% of
white maize, 50% of soybean and 85% of
cotton in South Africa (James, 2004). ). South
Africa now ranks eighth of GM crop producing
countries. Latest statistics from 2007 indicate
that 51% of yellow maize, 62% of white maize,
80% of soybean and 90% of cotton produced
were GM crops (Agri SA newsletter, Feb 2008).
