The deployment of products of genetically modified organisms (GMOs) continues to raise concerns and resistance, not only in Nigeria but across the world among consumers, researchers, public health experts, food sovereignty campaigners and others. Nigeria’s National Biosafety Management Agency (NBMA) however, has continued to take on a defensive front on the matter rather than acknowledging and addressing critical concerns that are quite fundamental and evident. This we believe comes from a mindset that assumes science and technology especially such as is approved by some foreign entities cannot be flawed and that Nigeria or Africa cannot make a headway in agriculture without without deploying biotechnology.
A recent article in The Guardian titled Nigeria Is Not Experimenting With GMOs, It Is Regulating Them, presents genetically engineered crops as a fait accompli and the NBMA as adequately defending Nigeria’s biosafety. The article almost reads like an NBMA public relations piece. The fact we must not forget is that the agency is saddled with the mandate to ensure that the practice of, and products from modern biotechnology do not harm human, animals, or plants health or the environment and they have said in the past that they are not set up to stop the deployment of GMOs but to regulate them. This begs for an interrogation of what regulation actually means. Shouldn’t regulation mean that GMOs should be banned altogether if they pose significant risks to humans and the environment? The the Precautionary Principle, a key principle of the Cartagena Protocol to which Nigeria is signatory, specifically advises caution and a halt in adoption of GMOs where there are threats to human and environmental safety.
One of the fundamental questions that the Nigerian government through the NBMA is yet to respond to is “ where are the results of LONG TERM and INDEPENDENT/PEER REVIEWED risk assessment including feeding tests conducted that informs the safety of the four officially approved products for commercial planting in Nigeria and the 10 or more others approved for food, feed and processing? This is unarguably the surest way to build trust in the regulatory architecture, but such information is not on the website of the NBMA as of 6 March 2026. We cannot but say the country is experimenting with GMOs using Nigerians as test subjects with our soils/environment as the laboratory. This is clearly not the way to defend biosafety.
The loudest argument about the need for GMOs in Nigeria is that there is no other way to feed a burgeoning population. The fact that these artificial crops do not have a yield advantage over natural varieties when cultivated under similar conditions is simply overlooked. The overriding impetus for the broadcasting of the GMOs in Nigeria is the economic benefits the speculators and manufacturers of the seeds would reap, riding on their power and control over policy formulation and implementation. Profit at what cost? Or is it true as an official of the All Farmers Association of Nigeria (AFAN) stated at a public hearing organised by the House of Representatives in December 2024 that “it is better to eat and die than not to eat and die”? Meaning that because Nigeria’s population is huge, we should keep deploying GMOs irrespective of the quality of the food and the long-term impacts whether social, health or environmental, as long as food is available.
But we must dig deeper even on the economic front. The cotton farmers who have planted GMOs for the longest time in Nigeria noted in 2024 that the GM Cotton (Bt Cotton) after 3 odd years of planting has not outperformed the conventional variety. They lamented that their soil was instead being degraded. This is possibly a result of the release of the CRY1Ab toxins (from Bacillus thuringiensis) in the Bt Cotton into the soils. Again, what cost are we willing to pay just to be in the league of countries deploying so-called cutting edge modern biotechnology in agriculture?
A second fundamental question that remains unanswered is who controls the GM seed market? This gives rise to several other questions: Who owns the intellectual property rights over the genetically modified seeds? Here’s the catch: GMOs can and will contaminate our local varieties through cross pollination and other processes. What safeguards has the NBMA put in place to prevent gene transfer and contamination of Nigeria’s local seed varieties? Or are we content with depending solely on the intentional seed companies for seeds and for our subsistence in the long run?
A number of other countries have put in place total or partial bans on GMOs based on this risk of genetic contamination. In 2024, Mexico placed an indefinite ban on genetically engineered corn. The courts said from the evidence before it, genetically engineered corn posed “the risk of imminent harm to the environment.” Furthermore, they will “suspend all activities involving the planting of transgenic corn in the country and end the granting of permission for experimental and pilot commercial plantings.” This ruling provided a protection for the 20,000 varieties of corn grown in Mexico and Central America. What are we doing to protect Nigeria’s genetic resources from GMOs contamination? Mexico is the centre of origin of maize and this reality places responsibility on her to protect natural maize varieties from the corruption of transgenic varieties. Nigeria is the centre of origin of beans/cowpea, and yet our farms and markets are open to insecticidal GMO beans.
On this note we encourage the government at all levels to invest in the setting up of seed banks to ensure the preservation of local and high performing indigenous seed varieties.
Nigerians reserve the right to choose their food. GMOs approved for commercial cultivation and sale are not labeled. Although we do not believe labelling will be effective considering our socio-economic context, the absence of labelling signals a disregard for the rights of consumers and an avoidance of responsibility on the part of the producers GMOs. Releasing GMOs into the market without labels is against the spirit and intent of the biosafety law in Nigeria. This explains why the National Biosafety Management Agency (NBMA) Act lacks provision on strict liability.
Many Nigerians are consuming imported processed foods bought from supermarkets without any idea that they are made from the genetically modified organisms (GMOs). The manner in which these items are imported into the country needs to be interrogated. Although the National Biosafety Management Agency (NBMA) has said illegal importation of GMOs into the country is being checked, these products are abundant in our market shelves (over 50 different brands including cereals, vegetable oils, spices, ice-cream, cake mixes etc) as revealed by a survey which Health of Mother Earth Foundation carried out across 10 Nigerian cities in 2018, 2019 and 2023.
We reinforce the call for a ban on GMOs in Nigeria. As recommended by the House of Representatives in 2024, no new GMOs should be approved in Nigeria pending a proper interrogation of the processes of approvals so far. We add that such an interrogation must include long term impacts on human and environmental health. The output of this exercise should be critically reviewed by independent scientists and other food system stakeholders.
Nigeria’s approach to tackling food insecurity should be such that address the root causes of the problem. We cannot overlook the poor budgetary allocation to agriculture or the heightened insecurity that keeps farmers out of farms or the lack of basic infrastructure or the poor extension service etc and claim to be addressing food insecurity.
It is time to transition back to agroecology -which simply means farming in line with nature and in the light of our socio-cultural, economic and ecological context. Farming that ensures that science recognises local knowledge and that it serves the interest of the people. We must promote and protect farming that assures food security but much better food sovereignty by ensuring shorter value chains/better access to food, improved livelihoods for smallholder farmers and a protection of the rights of peoples.
GMOs only attempt to address the symptoms of major underlying food system issues while increasing profit for their proponents. The price to pay in terms of ecological damage, loss of biodiversity, health and economic implications far outweigh any fickle advantages they may seem to have. It is time to decolonize our food systems.
People over profits!
