To many people around the world, the cassava is an exotic crop that they have never eaten. Or so they think. Yet anybody who has tasted tapioca pudding has profited from this versatile plant: Tapioca is a starch that comes from the cassava, a tropical shrub whose tuber is edible.

I dont eat much cassava either. Farmers dont grow it in my part of Kenya. Yet its a staple crop on my continenta rich source of carbohydrates for millions of Africans. Cassava is to the African peasant farmers what rice is to the Asian farmers, or what wheat and potato are to the European farmers, says Alfred Dixon of the International Institute of Tropical Agriculture.

In Tanzania, researchers have figured out how to improve the cassava through biotechnologya development that everyone ought to celebrate and promote.

This progress comes at a good time because the cassava brown-streak virus has become the leading threat to food security in many parts of East Africa. One study says that the disease can slash a farms productivity by as much as 70 per cent. When it strikes, many smallholder farmers simply abandon their fieldsand each time that happens, Africas dire food problems grow a little bit worse.

Biotechnology offers a potential solution. Scientists have learned how to trigger the cassavas immune-defense system, allowing the plant to fend off the lethal brown-streak virus. These miracle plants are currently in field trials in Tanzania. If the field trials go well, farmers and consumers across the region will benefit. In East Africa, this means many smallholder farmers will experience enhanced cassava production, and hence food security and incomes.

Yet that will happen only if politics doesnt get in the way of science. A l’Àfrica, unfortunately, politics always seems to intrude. Massa sovint, we turn over our public policies to special-interest groups that despise biotechnology for reasons of ideology.

The result is a tragedy for Africa. Our continent routinely fails to feed itself.

In the United States and elsewhere, GM crops have produced an enormous bounty. Aquest any, corn farmers in the Midwest are shattering all-time yield records, in large part because they can grow the best crops science can offer.

From the eyes of this African farmer, encara que, every year is a pretty good year for American growers. I wish we could enjoy similar levels of success.

The difference is technology. Americans have embraced itand now theyre growing more food than ever before. A l’Àfrica, our governments have resisted GM cropsand we continue to suffer from hunger and malnourishment.

Forty-seven countries occupy the continent of Africa, but only fourBurkina Faso, Egypt, Sud-Àfrica, and Sudanhave permitted the commercialization of GM crops. The rest of us must rely on farm technologies from the last century, even as we confront the 21st-century problems of climate change, environmental sustainability, and rapid population growth.

The cassava would be an excellent way to introduce more biotechnology into Africa. Most of its production goes straight into human bellies, feeding people directly. Its also an essential famine-reserve crop. When other staples struggle or fail due to disease or drought, many Africans turn to the cassava for basic sustenance.

So a cassava plant that fends off the deadly brown-streak disease would be a blessingand not just for the people who depend on this particular plant. Its commercial introduction could pave the way for Africa to accept more technology, especially in neighboring countries. Ara mateix, goods and services, including crops, move with relative ease across our borders.

If Tanzania were to permit the cultivation of GM cassava, consumers and farmers in Burundi, Rwanda, and Uganda would see the advantages and benefit in their food security strategies. My own country of Kenya, which shares a long border with Tanzania, might finally put an end to the delays that keep GM crops off our farms and abundant food off our plates.

Kenyan researchers already have tested GM varieties of cassava, blat de moro, cotó, sorghum, and sweet potato. We know theyre safe, both from our own research as well as from the widespread adoption and success of GM crops elsewhere. New research that will focus on Africas orphan crops, food crops like cassava that are not economically important to the global market but important fixtures in back gardens of rural Africa, by groups like the African Orphan Crops Consortium, will shield East African farmers from climate change and ultimately improve the diets of Africas children.

The only thing standing in the way is politics. Africans must allow science to trump fear and accept the technology thats improving food production almost everywhere else.

Lets start with the cassava in Tanzania.
