Will Frankenfood Feed the World?
If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions-and vocal green lobbies-the idea seems against nature.

In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the U.S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U.S. this year. The genetic genie is out of the bottle.

Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from-and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations, the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks?

The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. And by 2050, the U.N. estimates, it will probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the world's available cultivable land per person is declining. Arable land has declined steadily since 1960 and will decrease by half over the next 50 years, according to the International Service for the Acquisition of Agri-Biotech Applications (ISAAA).

The U.N. estimates that nearly 800 million people around the world are undernourished. The effects are devastating. About 400 million women of childbearing age are iron deficient, which means their babies are exposed to various birth defects. As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness. Tens of millions of people suffer from other major ailments and nutritional deficiencies caused by lack of food.

How can biotech help? Biotechnologists have developed genetically modified rice that is fortified with beta-carotene-which the body converts into vitamin A-and additional iron, and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to pests, drought, poor soil and crop viruses, bacteria or fungi.

Damage caused by pests is incredible. The European corn borer, for example, destroys 40 million tons of the world's corn crop annually, about 7% of the total. Incorporating pest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa, yields have increased significantly. So far, fears that genetically modified, pest-resistant crops might kill good insects as well as bad appear unfounded.

Viruses often cause massive failure in staple crops in developing countries. Two years ago, Africa lost more than half its cassava crop-a key source of calories-to the mosaic virus. Genetically modified, virus-resistant crops can reduce that damage, as can drought-tolerant seeds in regions where water shortages limit the amount of land under cultivation. Biotech can also help solve the problem of soil that contains excess aluminum, which can damage roots and cause many staple-crop failures. A gene that helps neutralize aluminum toxicity in rice has been identified.

Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and help prevent the loss of those crops after they are harvested.

Yet for all that promise, biotech is far from being the whole answer. In developing countries, lost crops are only one cause of hunger. Poverty plays the largest role. Today more than 1 billion people around the globe live on less than $1 a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to grow them or if the local population cannot afford to buy the food those farmers produce.

Nor can biotech overcome the challenge of distributing food in developing countries. Taken as a whole, the world produces enough food to feed everyone-but much of it is simply in the wrong place. Especially in countries with undeveloped transport infrastructures, geography restricts food availability as dramatically as genetics promises to improve it.

Biotech has its own "distribution" problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for poor farmers in the developing world, and many of those products won't even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companies are responding to the needs of poor countries. A London-based company, for example, has announced that it will share with developing countries technology needed to produce vitamin-enriched "golden rice."

More and more biotech research is being carried out in developing countries. But to increase the impact of genetic research on the food production of those countries, there is a need for better collaboration between government agencies-both local and in developed countries-and private biotech firms. The ISAAA, for example, is successfully partnering with the U.S. Agency for International Development, local researchers and private biotech companies to find and deliver biotech solutions for farmers in developing countries.

Will "Frankenfoods" feed the world? Biotech is not a panacea, but it does promise to transform agriculture in many developing countries. If that promise is not fulfilled, the real losers will be their people, who could suffer for years to come.
 
Biotechnology Confirmed food solution in Nigeria

The International Food Policy Research Institute (Ifpri) has called on Africa to use the advantages inherent in Biotechnology to bring and end to the endemic problems of Hunger and poverty in the continent.

A statement from the organisation explained that Research into genetically modified (GM) crops is crucial to improving food security and reducing poverty in Africa.

"Food security is of serious concern to the African continent and public sector research into GM foods is of direct importance to the smallholder farmers, who need something both to eat and to sell,"

"Current biotech research has the potential to reduce the use of pesticides, increase drought tolerance and improve the nutritional value of staple foods," Ifpri said in the statement

The statement, which was based on the findings of a study on the development of GM crops by public research institutes in Egypt, Kenya, South Africa and Zimbabwe, stressed that despite the common view that corporations drove the GM food agenda, a few African countries had vibrant public biotech research programmes.

Ifpri said improvements in crops brought about by public biotech research could "benefit the environment, improve health, reduce the cost of food and increase the incomes of poor smallholder farmers throughout Africa". According to the organisation, a 10 percent increase in the level of agricultural productivity was associated with a 7.2 percent reduction in poverty.

Cohen said research into GM crops by African governments often targeted the improvement of indigenous plant varieties relevant to local use by small-scale farmers. Kenya, for example, was engaged in public biotech research into producing drought-resistant maize; Uganda was involved in researching insect-resistant bananas.

He emphasised the importance of GM research in Africa reaching a stage where it could help the farmers, noting that "if the research stays in the lab, there will be no benefit to the farmers". However, the introduction of GM seeds into African soil and GM crops into indigenous markets is an issue that remains extremely contentious; critics have argued that biotechnology is not the solution to Africa's poverty and hunger.

"We have not exploited research into conventional seeds enough," Angela Wauye, officer in charge of food security at Action Aid Kenya, told Irin. "In Kenya, we are not ready to handle GM crops - we do not even have a biosafety bill in place."

Cohen stressed that the agency was interested in "biosafety first", saying all plants produced by the various public biotech research institutes were submitted for review to the relevant national biosafety channels and regulatory bodies.

"We must address the real reasons our agricultural sector is performing so dismally," Wauye said. "Poor farmers must be empowered by the government to be able to access credit, cheaper farm inputs and better infrastructure."

She pointed out that "because of poor roads, transporting crops from Marsabit [northern Kenya] to [the eastern Kenyan port of] Mombasa is more expensive than transporting the goods from Mombasa to Europe."

Wauye also said not enough was known about the effects of GM crops on the environment and on human health. "We may not have seen any effects of GM crops so far, but more research needs to be done into their side effects over prolonged periods."

Although research was a very important component of the struggle to end hunger, Wauye noted that it was important to focus the research on issues that were relevant to Africa. "The research must be driven by national needs - we must be our own agenda-setters," she added.

As the need to ensure sustainable management of world fisheries increases, biotechnology is becoming a useful tool in ensuring the most effective and sustainableuse of fisheries.

A statement from Agbioview explains that a genetically modified plant that produces all the healthy fats found in oily fish has been developed by British scientist therefore ensuring that exploitation of Oily fish is reduced to sustainable levels .

The weedy type of cress was genetically upgraded to make it rich in polyunsaturated fats known as omega-3 and omega-6 fatty acids. The fats are believed to help reduce heart disease and, according to some scientists, improve brain function and mood.

According to the report, Baoxiu Qi and Colin Lazarus, plant biologists at Bristol University, developed it as an alternative source of the fats. Oily fish are especially rich in omega-3; omega-6 is found in certain grains and poultry.

The cress was modified with genes taken from three different microorganisms and its production of the fats raises hopes that plants will one day be a viable alternative source.

"The next step is to add the same set of genes to leafy salad vegetables such as spinach and lettuce," said Mr. Lazarus.

The use of modified plants would take the pressure off severely depleted fish stocks. The potential benefits do not end there, according to the biologists.

Oils made from the plants are also likely to be more pure than many fish oil supplements. People with diets lacking in the fats from fish, such as vegans, may stand to benefit. "The problem is that the people most likely to benefit from eating these plants are the most unlikely to go near them because they are genetically modified," Mr. Lazarus said.

Fish and chicken are among the primary sources of omega-3 and omega-6 fatty acid, but other food contain them, albeit in smaller quantities. Walnuts, flax seed oil and hemp all contain omega-3 while olive oil and other vegetable oils are rich in omega-6 fatty acids.

Liz O'Neil, of the Vegetarian Society, was not convinced that vegetarians would welcome the development. "We're not crying out for it," she said. "If you make sure you eat the right foods, you can already get all the omega-3 and omega-6 oils you need. There are issues with GM and it's certainly not popular among our members."

The Vegan Society was also skeptical. "At the end of the day, this is not about human good, it's about making a profit," a spokesman said.

According to Dr., Lazarus, whose work is published in the journal Nature Biotechnology today, the plants could be turned into animal feed and used in the battle against global warming.

Cows and other ruminants belch out vast quantities of methane, which accelerates warming. "If you feed cattle and sheep these polyunsaturated fats, they expel much less methane," Mr. Lazarus said. The work was funded by the German crop biotechnology company BASF.
