Attempts to genetically modify food staples, such as crops and cattle, to increase their nutritional value and overall performance have prompted world-wide criticism by environmental, nutritionists and agriculture experts, who say that protecting and fomenting biodiversity is a far better solution to hunger and malnutrition.

Two cases have received world-wide attention: one is a project to genetically modify bananas, the other is an international bull genome project.

In June, the Bill & Melinda Gates Foundation announced that it has allocated some 10 million dollars to finance an Australian research team at the Queensland University of Technology (QUT), working on vitamin A-enriched bananas in Uganda, by genetically modifying the fruit.

On the other hand,  according to its project team, the “1000 bull genomes project” aims “to provide, for the bovine research community, a large database for imputation of genetic variants for genomic prediction and genome wide association studies in all cattle breeds.”“It makes little sense to support genetic engineering at the expense of (traditional, organic) technologies that have proven to substantially increase yields, especially in many developing countries” – ‘Failure to Yield’, a study by the U.S. Union of Concerned Scientists

In both cases, the genetic modification (GM) of bananas and of bovines is an instrument to allegedly increase the nutritional value and improve the overall quality of the food staples, be it the fruit itself, or, in the case of cattle, of meat and milk.

James Dale, professor at QUT, and leader of the GM banana project, claims that “good science can make a massive difference here by enriching staple crops such as Ugandan bananas with pro-vitamin A and providing poor and subsistence-farming populations with nutritionally rewarding food.”

In the ‘1000 bull genomes project’, the scientists involved (from Australia, France, Germany, and other countries) have sequenced – that is, established the order of – the whole genomes of hundreds of cows and bulls. “This sequencing includes data for 129 individuals from the global Holstein-Friesian population, 43 individuals from the Fleckvieh breed and 15 individuals from the Jersey breed,” write the scientists in an article published in Nature Genetics of July 13.

The reactions from environmental activists, nutritionists, and scientists could not be more critical. The banana case has even prompted a specific campaign launched in India – the “No to GMO Bananas Campaign”.

The campaign, launched by Navdanya, a non-governmental organisation founded by the international environmental icon Vandana Shiva, insists that “GMO bananas are … not a solution to” malnutrition and hunger.

The group argues that so-called bio-fortification of bananas – “the genetic manipulation of the fruit, to cut and paste a gene, seeking to make a new or lost micronutrient,” as genetic expert Bob Phelps has put it – is a waste of time and money, and constitutes a risk to biodiversity.

“Bananas are highly nutritional but have only 0.44 mg of iron per 100 grams of edible portion,” a Navdanya spokesperson said. “All the effort to increase iron content of bananas will fall short the (natural) iron content of indigenous biodiversity.”

The rationale supporting bio-fortication suggests that the genetic manipulation can multiply the iron content of bananas by six. This increase would lead to an iron content of 2.6 mg per 100 grams of edible fruit.

“That would be 3,000 percent less than iron content in turmeric, or lotus stem, 2,000 percent less than mango powder,” the spokesperson at Navdanya said. “The safe, biodiverse alternatives to GM bananas are multifold.”

Scientists have indeed demonstrated that the GM agriculture has so far failed to deliver higher yields than organic processes.

In a study carried out in 2009, the U.S. Union of Concerned Scientists demonstrated that the yields of GM soybeans and corn have increased only marginally, if at all. The report, “Failure to Yield“, found out that increases in yields for both crops between 1995 and 2008 were largely due to traditional breeding or improvements in agricultural practices.

“Failure to Yield” also analyses the potential role in increasing food production over the next few decades, and concludes that “it makes little sense to support genetic engineering at the expense of (traditional, organic) technologies that have proven to substantially increase yields, especially in many developing countries.”

Additionally, the authors say, “recent studies have shown that organic and similar farming methods that minimize the use of pesticides and synthetic fertilizers can more than double crop yields at little cost to poor farmers in such developing regions as Sub-Saharan Africa.”

Yet another ground for criticism is the fact that Bill Gates has repeated an often refuted legend about the risk of extinction of the banana variety Cavendish, grown all over the world for the North American market.

In his blog, Gates claims that “a blight has spread among plantations in Asia and Australia in recent years, badly damaging production of … Cavendish. This disease, a fungus, hasn’t spread to Latin America yet, but if it does, bananas could get a lot scarcer and more expensive in North America and elsewhere.”

The risk of extinction, however, is practically inexistent, as the United Nations Food and Agricultural Organisation (FAO), among other institutions, had already shown in 2003.

“What is happening is the inevitable consequence of growing one genotype on a large scale,” said Eric Kueneman, at the time head of FAO’s Crop and Grassland Service. That is, monoculture is the main cause of the fungus.

“The Cavendish banana is a “dessert type” banana that is cultivated mostly by the large-scale banana companies for international trade,” recalled Kueneman, today an independent consultant on agriculture.

On the other hand, as FAO numbers show, the Cavendish banana is important in world trade, but accounts for only 10 percent of bananas produced and consumed globally. Virtually all commercially important plantations grow this single genotype, and by so doing, make the fruit vulnerable to diseases. As FAO said in 2003, “fortunately, small-scale farmers around the world have maintained a broad genetic pool which can be used for future banana crop improvement.”

Actually, the most frequent reasons for malnutrition and starvation can be found in food access, itself a consequence of poverty, inequity and social injustice. Thus, as Bob Phelps, founder of Gene Ethics, says, “the challenge to feed everyone well is much more than adding one or two key nutrients to an impoverished diet dominated by a staple food or two.”

The same goes for the genome sequencing of bulls and cows, says Ottmar Distl, professor at the Institute for Animal Breeding and Genetics at the University of Hannover. “Some years ago, we thought that it would impossible to obtain more than 1,000 kilograms of milk per year per cow,” Distl said. “Today, it is normal to milk 7,000 kilograms, and even as much as 10,000 kilograms per year.”

But such performance has a price – most such “optimised” cows calve only twice in their lives and die quite young.

And yet, the leading researchers of the “1000 bull genomes project” look at further optimising the cows’ and bulls’ performance by genetic manipulation of the cattle in order to, as they say in their report, meet the world-wide forecasted, rising demand for milk and meat.

Distl disagrees. “Whoever increases the milk output hasn’t yet done anything against worldwide malnutrition and hunger.” In addition, he warned, the constant optimisation of some races can lead to the extinction of other lines, thus affecting the populations depending precisely on those seldom older races.

It goes without saying that such an extinction would hardly serve the interests of the world’s consumers.

NEW DELHI, Jun 14 2013 (IPS)

India’s environmental and food security activists who have so far succeeded in stalling attempts to introduce genetically modified (GM) food crops into this largely farming country now find themselves up against a bill in parliament that could criminalise such opposition.

"If the new bill is passed...it will only be a matter of time before India becomes a GM banana republic." -- Devinder Sharma
The Biotechnology Regulatory Authority of India (BRAI) bill, introduced into parliament in April, provides for ‘single window clearance’ for projects by  biotechnology and agribusiness companies including those to bring GM food crops into this country, 70 percent of whose 1.1 billion people are involved in agricultural activities.

“Popular opposition to the introduction of GM crops is the result of a campaign launched by civil society groups to create awareness among consumers,” said Devinder Sharma, food security expert and leader of the Forum for Biotechnology and Food Security. “Right now we are opposing a plan to introduce GM bananas from Australia.”

Sharma told IPS that if the BRAI bill becomes law such awareness campaigns will attract stiff penalties. The bill provides for jail terms and fines for “whoever, without any evidence or scientific record misleads the public about the safety of organisms and products…”

Suman Sahai, who leads ‘Gene Campaign’, an organisation dedicated to the conservation of genetic resources and indigenous knowledge, told IPS that “this draconian bill has been introduced in parliament without taking into account evidence constantly streaming in from around the world about the safety risks posed by GM food crops.”

She said that Indian activists are now studying a new report published in the peer-reviewed Organic Systems Journal by Judy Carmen at Flinders University in Adelaide, Australia, showing evidence that pigs fed on GM corn and soy are likely to develop severe stomach inflammation.

“The new bill is not about regulation, but the promotion of the interests of food giants trying to introduce risky technologies into India, ignoring the rights of farmers and consumers,” Sahai said. “It is alarming because it gives administrators the power to quell opposition to GM technology and criminalise those who speak up against it.”

The past month has seen stiff opposition to plans to introduce GM bananas into India by a group of leading NGOs that includes the Initiative for Health & Equity in Society, Guild of Services, Azadi Bachao Andolan, Save Honey Bees Campaign, Navdanya and Gene Ethics in Australia.

These groups are seeking cancellation of a deal between the Queensland University of Technology (QUT) and India’s biotechnology department to grow GM bananas here.

Vandana Shiva, who leads the biodiversity conservation organisation Navdanya, and is among India’s top campaigners against GM crops, told IPS that such food crop experiments pose a “direct threat to India’s biodiversity, seed sovereignty, indigenous knowledge and public health by gradually replacing diverse crop varieties with a few patented monocultures.”

She fears that an attempt is being made to control the cultivation of bananas in India through patents by “powerful men in distant places, who are totally ignorant of the biodiversity in our fields.”

India produces and consumes 30 million tonnes of bananas annually, followed by Uganda which produces 12 million tonnes and consumes the fruit as a staple.

India’s National Research Centre for Banana (NRCB), which has preserved more than 200 varieties of the fruit, is a partner in the GM banana project. Others include the Indian Institute of Horticulture Research, the Bhabha Atomic Research Centre (BARC) and Tamil Nadu Agricultural University.

With so much official involvement there are fears that GM bananas may eventually find their way into nutrition programmes run by the government. “There is a danger that GM bananas will be introduced into such programmes as the integrated child development scheme and the midday meals for children,” Shiva said.

India’s Integrated Child Development Services (ICDS), the world’s largest integrated early childhood programme, began in 1975 and now covers 4.8 million expectant and nursing mothers and over 23 million children under the age of six. Bananas are included as part of the meals served in many of the 40,000 feeding centres.

QUT’s Prof. James Dale, who leads the project, has, in interviews given to Australian media, justified the GM experiment by saying that it will “save Indian women from childbirth death due to iron deficiency.”

According to studies conducted by the International Institute for Population Sciences in Mumbai, more than 50 percent of Indian women and more than 55 percent of  pregnant women in India are anaemic. It is estimated that 25 percent of maternal deaths are due to complications arising out of anemia.

In a Mar. 9, 2012 interview with the Australian Broadcasting Corporation, Dale said, “One of the major reasons around iron is that a large proportion of the Indian population are vegetarians and it’s very difficult in a vegetarian diet to have intake of sufficient iron, particularly for subsistence farming populations.

“India is the largest producer of bananas in the world but they don’t export any; all of them are consumed locally. So it’s a very good target to be able to increase the amount of iron in bananas that can then be distributed to…the poor and subsistence farmers.”

Dale denied in the interview that there were risks to existing Indian banana strains and said because bananas were sterile there is no danger that the genes being introduced will enter and destroy other varieties.

But experts like Shiva have challenged Dale’s claim. She said Australian scientists are using a virus that infects the banana as a promoter and that this could spread through horizontal gene transfer.

“All genetic modification uses genes from bacteria and viruses and various studies have shown that there are serious health risks associated with GM foods,” she stressed, adding that there are safer, cheaper and more natural ways to add iron to diets.

India is the world’s biggest grower of fruits and vegetables with many varieties naturally rich in iron. “Good sources of dietary iron in India included turmeric, lotus stem, coconut, mango (and) amaranth…there is no need to genetically modify banana, a sacred plant in India,” she said.

Attempts by IPS to contact Dale directly and separately through QUT’s press relations department on the risks from horizontal gene transfer and the possible danger to public health failed to elicit any response.

According to Shiva there is a concerted move by food corporations to control important food crops and staples in their centres of origin. “We have seen GM corn introduced into Mexico and there was a determined attempt to introduce GM brinjal in India.”

In February 2010, the then minister for environment, Jairam Ramesh, ordered a moratorium on the brinjal project and his action was seen as a major blow to the introduction of GM food crops in India.

“If the new bill is passed, we could have a reversed situation and projects like GM bananas will be quickly cleared with the backing of the government – and it will only be a matter of time before India becomes a GM banana republic,” Sharma said.
