Despite public
perception about and/or outcry against crop and animal breeding and
manufacturing of medicines through biotechnology also known as genetically
modified organisms (GMOs), some leading Ghanaian scientists still insist the
consumption of products resulting from biotechnology processes are safe and
should be fully adopted.
Like many proponents,
Professor Kenneth Ellis Danso, Director of Biotechnology and Nuclear Agriculture
Research Institute (BNARI) of the Ghana Atomic Energy Commission, said biotechnology applications allow
the creation of new plant varieties and animal breeds with higher yields
thereby ensuring food security.
He posits that,
biotechnology leads to higher economic benefits for resource poor farmers because
unlike conventional agriculture, a farmer who depends on biotechnology need not
farm several acres of land, use so much pesticides, weedicides and fertiliser to
control pests, weeds and enhance crop yields. “Biotechnology or genetic
modification promotes pests and diseases resistance in crops and yields
plentifully”, Prof. Danso intimated.
He also cited cassava
brown streak virus (CSBV), one of the most damaging viral diseases of cassava
in East Africa, saying “There is no known solution to this viral disease since
all varieties are susceptible to the virus. Genetically modified cassava can be
used to overcome the problem of CSBV”, he stated.
At a forum of
scientists, researchers, students, ministers of state and parliamentarians at
the Savanna Agricultural Research Institute (SARI) at Nyankpala in the Northern
Region, Prof. Danso gave solid reasons for Ghana to fully adopt biotechnology.
But other people at the forum also raised serious concerns about the safety of biotechnology
to human health and the environment.
The forum, which
was organised by Program for Biosafety Systems
(PBS) of the International Food
Policy and Research Institute (IFPRI), was intended to dispel the myths
and misconceptions surrounding the use of biotechnology and shed more light on
the benefits producers (farmers) and consumers can derive from it.
The forum, according
to Daniel Osei Ofosu, Country Coordinator, PBS, was also to let many of the
attendees see for the first time, field experiments of two varieties of Bt cotton
which have been cultivated by SARI through biotechnology on a small scale to study
their prospects with regard to pests’ resistance.
According to Prof. Danso, currently a number of crops
have been genetically modified, citing maize (corn), cotton, soya bean, cowpea
and pawpaw, adding that “Currently, Ghana has approved five confined field
trials of GMOs one of which involves stacked genes. Of these are Bt cotton, Bt
cowpea and NEWEST rice which are grown under confined field trials”, he said.
The World Health Organisation (WHO) defines GMOs as
organisms (plants, animals or microorganisms) in which the genetic material
(DNA) has been altered in a way that does not occur naturally by mating and/or
natural recombination.
The technology is also called “modern biotechnology”
or “gene technology”, sometimes also “recombinant DNA technology” or “genetic
engineering”. It allows selected individual genes to be transferred from one
organism into another, also between nonrelated species. Foods produced from or
using GMOs are often referred to as GM foods.
Many academic reports including one by Erica Kannal, a
dietician and certified health/fitness specialist with the America College of
Sports Medicine, suggest that GM foods are relatively new to the food supply,
and people have only been consuming these foods since the mid-1990s when the
first GM tomatoes appeared in grocery stores.
In an article she published in February 2014, Erica said:
“There is no long-term data on how genetically modified foods affect human
health. Clinical trials done on animals that were fed GM crops are of short
duration and show mixed outcomes”.
She said a study published in the "International
Journal of Biological Sciences" in December 2009, notes that rats fed GM
corn had a decline in liver, kidney, heart, adrenal gland and spleen health and
function. “Short-term studies in which animals were fed GM foods for only 4
weeks usually show few negative side effects. No research has been conducted on
the health and safety for people who eat GM foods”, Erica stated.

According to Erica, in addition to one’s health, GM
foods may have negative side effects on the environment, because “crops are
often sprayed with powerful pesticides and herbicides, and are fertilized with
chemical fertilizers. These chemicals then contaminate the environment by
traveling through the air; they leach into the ground, where they end up in
fresh-water sources. Weeds have begun to develop a resistance to some of these
chemicals – which means that in the future, it will be more difficult to
control noxious plants”, she stressed.
Erica further pointed out that, wind also carries the
pollen from GM crops to neighbouring farms where seed stock is then
cross-contaminated with GM pollen. “Over time, this leads to a reduction in the
biodiversity of crop strains. Insect populations may also be harmed by GM crops
that produce pesticides”, she observed.
However, the Country Coordinator of PBS Daniel Osei told
the Nyankpala forum that, “all new products (GM) are carefully tested for
safety related to animal and microbial life” before they are produced for
consumption. “Soil persistence and the likelihood of surface and subsoil water
effects are also considered”, he emphasised.
He dispelled claims by anti-GM campaigners, that Ghanaian
farmers will be forced to buy seeds every year from multinational companies to
sow, stressing that, even before GM applications are fully adopted by the
government of Ghana, many farmers buy improved seeds every season for sowing. “No
one is going to force farmers to plant GM. Those who are practicing
conventional agriculture can continue to practice…….it’s only when you’re
interested in GM you can buy GM seeds to cultivate and follow the lay down regulations
set by regulatory bodies”, he opined.

Daniel Osei also indicated that, “the body of existing
scientific evidence leads to the conclusion that there are no increased adverse
health and environmental effects attributable to the use of recombinant DNA
biotechnology in food production”.
“With the current higher degree of regulatory
oversight for all foods derived from recombinant DNA biotechnology, there is
less likelihood of adverse effects to consumers than with new conventional
foods. The agricultural biotechnology industry would benefit from a regulatory
system that increases consumer confidence in food product safety”, Daniel Osei
claimed.
Meanwhile, on May 24, 2014, millions of people from
around the world participated in a “March Against Monsanto”, calling for the
permanent boycott of GM foods and other harmful agro-chemicals being
manufactured by Monsanto, a U.S.-based multinational reported to have been
spearheading the global campaign for GMOs. Marches occurred on six continents,
in 52 countries, with events in more than 400 cities, including 47 U.S.
states.
GMOs, according to EcoWatch.Com,
have been partially banned by Austria, Bulgaria, Germany, Greece,
Hungary, Ireland, Japan, Luxembourg, Madeira, New Zealand, Peru, South America,
Russia, France, Switzerland and Costa Rico, and are currently labelled in 62
countries. In India, more than 250,000 farmers have committed suicide
after Monsanto’s Bt cotton seeds did not perform as promised. Farmers, left in
desperate poverty, are opting to free their families of debt by drinking
Monsanto pesticide, thereby ending their lives.
