In
spite of the large tracks of arable land in Ghana and most of Africa, famine is
rife and more continue to die of hunger. Charles
Benoni Okine writes about using new scientific ways to improve food yields
and the caution.
In many developing
countries across the world, food shortage is a major issue.
Apart from the lack of
rain and poor irrigation to grow crops, there is also the serious issue about
the invasion of millions of acres of farmlands by all manner pests which feed
on the agricultural produce.
As a result, famine is
killing millions of people and governments are desperate to find permanent
solutions to problem.
In their quest to do so,
there is the temptation for them to adopt one or more of the new various
scientific methods to either increase yield or control the invasion of pests on
their farmlands.
One of these scientific
techniques in food production which has been under contention for years is the
genetically modified organism foods (GMO foods) which some countries have
adopted.
Others are skeptical because
of the misconceptions or otherwise created around its adoption.
In Ghana much as there
has not made any formal pronouncements on whether to start growing GMO foods,
its adoption could be out of desperation.
For instance, there are
plans underway to use GMO techniques to boost cotton production in the northern
part of Ghana, using the success story of Burkina Faso’s BT Cotton as a test
case.
BT cotton is said to be
fetching that country more foreign exchange as yields have increased from as
little as 40,000 tonnes to about 600,000 tonnes per annum.
A GMO (genetically modified organism) is the result of a
laboratory process of taking genes from one species and inserting them into
another in an attempt to obtain a desired trait or characteristic, hence they
are also known as transgenic organisms.
This process may be called either Genetic Engineering
(GE) or Genetic Modification (GM); they are one and the same.
How is
genetic engineering done?
In
order to breach these natural barriers and make possible the introduction of
DNA from a different species, genetic engineers have to find ways to force the
DNA from one organism into another. These methods include:
- Using viruses or bacteria to "infect" animal or plant cells with the new DNA.
- Coating DNA onto tiny metal pellets, and firing it with a special gun into the cells.
- Injecting the new DNA into fertilized eggs with a very fine needle.
- Using electric shocks to create holes in the membrane covering sperm, and then forcing the new DNA into the sperm through these holes.
What
combinations have been tried?
It is
now possible for plants to be engineered with genes taken from bacteria,
viruses, insects, animals or even humans. Scientists have worked on some
interesting combinations:
- Spider genes were inserted into goat DNA, in hopes that the goat milk would contain spider web protein for use in bulletproof vests.
- Cow genes turned pigskins into cowhides.
- Jellyfish genes lit up pigs' noses in the dark.
- Artic fish genes gave tomatoes and strawberries tolerance to frost.
- Potatoes that glowed in the dark when they needed watering.
- Human genes were inserted into corn to produce spermicide.
Caution
The Executive Secretary
of the African Capacity Building Foundation (ACBF), Dr Frannie Léautier, has said
the adoption GMOs is not in itself a bad practice because of the positivity on
crop and animal yields.
However, she cautioned
that Ghana and other countries in the developed world that intends to adopt
that technique must be able to exercise the greatest caution before adopting
any new ways of increasing agricultural yields using GMO techniques.
For instance, she noted
that the adoption of techniques for genetically modified foods in particular
required the right capacities to be able to realise its fullest impact of
improved yield.
She told a cross section
of the media in Accra that to be able to properly adopt that GM technique, the
analysis must be right.
There is the need for a
country wanting to adopt it to “have the capacity for biosafety, have capacity
to run experiments to test them and capacity to pilot to scale and those that
have these and more can be considered ready for GMOs”.
“So if you do not have
that then there is a serious issue at stake and because once started it could
be a difficult thing to unwind”, she said.
Ms Léautier said “look
at cotton in Burkina Faso, banana in Uganda and cassava in Nigeria. These may
be successful but those countries that have not had the real capacities to
experiment before adopting cannot properly manage the situation and there can
be challenges that will affect food yields, something which is not the
intention.”
“Key issue is to build
the capacity for running these experiments and tests focusing on species that
are naturally around so they do not have negative effect on the ecosystem and
particularly the transmission of diseases”, she warned.
Ms Léautier said it
could be considered in the Sahel regions and where drought resistant varieties
could be very popular in an attempt to see the nutrition fortified for the
people.
Way
Forward
It is obvious that there
are good sides of the GMO foods. But at the same time it can be injurious to a
country’s economy because the needed yields may not be achieved to solve the
shortages.
It is therefore obvious
that the right capacities need to be adopted to ensure that the right things
are done to avert a calamity and to win the confidence of the people (both
farmers and the masses) to use it.
Ghana can but there is
no need for a rush.
