Abstract |

Biotechnology is the formation of new heritable
materials by insertion of nucleic acid molecules
produced outside a cell by vector systems. The
underlying principles involve dissection of
desirable characters using restriction enzymes that
protect host DNA by introducing methyl groups at
recognition sites. These enzymes produce sticky
ends that allow for ligation using phosphodiester
bonds, and cloning vehicles (replicons) with high
gene dosage allowing for modification in
biotechnology. This second generation biotechnology
premise give speed and precision, yet only
compliments the traditional breeding programs, by
re-invigorating life expectancy, productivity,
growth in food and agricultural sustainability. USA
(68%) Argentina (23%) Canada (7%) China (1%) and
South Africa (1%) are fore runners in commercial GM
–food production. Most modified crops are corn and
soy bean (84%) rap seed (canola) cotton and potatoes
(18%), reasons for modification include herbicide
tolerance (74%), pest and disease resistance (19%)
and biofortification (7%), between 109-120 million
acres of land are used for cultivation of GM foods.
As the world population quadruples, the only
promising tool against global hunger is
biotechnology. Nevertheless, are GM foods safe for
us? Several criticism advanced are classed as
environmental hazards, human health risks,
economical and ethical reasons. Most regulatory
agencies stance are GM foods are substantially safe,
yet insist on mandatory labeling as ‘GRAS’ with 0%
contamination, while importing countries have the
right to accept or reject GM foods. We are
optimistic that modified food aid will deal with the
threatening starvation in sub-Saharan Africa with
rampant civil unrest, political corruption and
failed agricultural programmes. The only challenges
are lack of infrastructures for storage,
transportation, insecurity of aid workers and non
acceptance. It would be unwise to believe that food
insecurity can be eliminated without Agricultural
biotechnology.

insecurity; World Food Aid Programmes.
