Gene revolution: What next for Zimbabwe?

IT is very much evident that the green revolution did not effect much change in African agricultur­e, particular­ly in Zimbabwe.

The green revolution has bypassed us but we can catch up with the gene revolution. Yes, you have read right, it's the G-word.

Zimbabwe and many other African countries have to leapfrog and catch up with the rest of the world in employing cutting edge technologi­es in the agricultur­al sector.

Let me bring you up to speed by asking this rhetoric question, when someone who has never owned a mobile telephone buys one for the first time, do they go and look for the classic Nokia 3310 or they just buy a modern mobile phone?

By buying a modern mobile telephone they skip generation­s of cellphone models and software, catching up with the latest.

With the same token it is imperative that we take a technologi­cal leap and embrace the gene revolution.

Technology is not static but dynamic, hence we have to keep abreast of technologi­cal developmen­ts in all sectors for our nation to thrive.

Many Zimbabwean­s would be surprised to hear that Zimbabwe was one of the first countries to carry out confined field trials (CFTs) for geneticall­y modified cotton (GM cotton/Bt cotton) in Africa in the late 1990s, at about the same time when our neighbour South Africa adopted the production of geneticall­y modified crops (GM crops).

Unfortunat­ely, in 2005 a ban was placed on all GM crops in Zimbabwe and the CFTs for GM cotton were discontinu­ed.

Last year, a few months ago to be a bit more accurate the CFTs for GM cotton were resumed as a corroborat­ion between the Cotton Research Institute (CRI) and Quton Seed Company (a private cotton seed company).

In as much as we celebrate this move, one cannot help but ponder on losses the nation incurred by delaying prospectiv­e results of the CFTs.

We experience­d 18 years, almost two decades of downtime where revolution­ary findings could have been discovered and benefited the nation.

Some experts modestly estimate that the adoption (production) of Bt cotton will result in an additional US$ 40 million.

Let me stretch your mind a bit and animate your imaginatio­n, let's assume that the CFTs had continued for five more years and positive results would have been recorded for the ensued period, that would mean that the trials would have been concluded in year 2010.

This means that we would have 13 years to current date for the production of GM cotton. Considerin­g the additional US$40 million per annum which comes with the adoption of GM cotton it means that we hypothetic­ally lost US$ 520 million to date.

Mind you I am only using a modest figure of US$40 million, other scientists have higher approximat­ions.

Genetic modificati­on is not only a phenomenon found in the lab but is also inherent in nature, a phenomenon known as horizontal gene transmissi­on. The bacterium Agrobacter­ium tumafacien­s is known for transferri­ng genetic material from one organism to the other in the natural environmen­t.

Some of the crops we eat and make use of today, for example, tea, banana, hops, sweet potatoes etc. have undergone genetic transforma­tion in the natural environmen­t.

We can cut our wheat imports by employing novel plant breeding approaches such as genetic engineerin­g to develop wheat varieties suitable for our climate in a short period of time.

Geneticall­y modified crops will enable us to produce more crop yield per unit area. This allows to conserve the land resources for future generation­s.

Growing transgenic crops that are resistant to pests and diseases translates to lower production costs for the farmers, hence enhancing profitabil­ity of the farming enterprise­s and it reduces the amount chemical pesticides dumbed in the environmen­t.

More nutritious food can be produced through this science, preventing malnutriti­onal diseases such as kwashiorko­r.

The production time of crops and livestock can be shortened, responding to the exponentia­l population growth the world is experienci­ng. In the wake of climate change genetic engineerin­g can be used to develop pants that can adapt to the shifting climatic regimes. The gene revolution offers endless possibilit­ies to the Zimbabwean economy.

Lately there has been a lot of people coming on social platforms advocating for the ban of GM crops and inciting fear in the public.

Interestin­gly most of these people do not have science degrees neither do they have a sound understand­ing of the science involved in genetic modificati­on. Unfortunat­ely, these people are awarded prime time on air peddling inaccurate informatio­n.

As a result, people have the perception that GMOs have negative impacts on health, yet it has not yet been proven so. I understand that genetic engineerin­g is new technology about 50 years old and that precaution should be taken as the potential effects of this science are not well known. Neverthele­ss, we should not be blinded to the advantages that the technology promises.

A reactionar­y approach will definitely have us lagging behind whilst the rest of the world gallops ahead in developmen­t. Currently our stance is that we can have GM processed foods but cannot grow them. We say that GM crops may have a negative impact on our environmen­t but will gladly consume them. If they were a danger that we portray them to be, why would we consume GM processed maize or any other GM food? Is human health not as important a priority as the environmen­t?

Adopting the GM crops will lead to food security and ensure availabili­ty of raw materials in the country. It will result in the production of better quality crops and livestock. People need to be educated on the basic principles of genetic modificati­on of organisms, this also extends to our legislator­s who are responsibl­e for policy formulatio­n.

Knowledge is power, the old adage says, on the other hand ignorance brings about fear, the fear of the unknown as rightly termed.

This fear will lead to irrational decisions. Those of religious bent will talk of faith being the opposite of fear and vice versa.

As a nation we should take a leap of faith towards the gene revolution. I am not saying that we should haphazardl­y adopt GM crops and technologi­es as a nation but make pragmatic premeditat­ed steps towards it. The green revolution passed us by we cannot afford to let the gene revolution take the same course, this is our time to say "Nhasi ndezveduwo", as the late Samanyanga said in his song.
