voa英语:Growing Food From Air in Nigeria

A group of farmers in Nigeria is using a technology-based method to grow crops from moisture in the air.

The method, known as aeroponics, does not involve soil. Instead, plant roots hang in the air. The roots take in a nutrient solution from a watery mist.

Aeroponics is not well-known in Nigeria, but farmers there are working to make the technique more popular.

The technique could make a big difference in places like the city of Abeokuta. Violence and desertification -- the process by which fertile land becomes desert -- have made huge amounts of land unfarmable.

Biochemist Samson Ogbole is popularly known as Nigeria's smart farmer. He and his team are growing crops without soil at the technology-based farm they started three years ago in Abeokuta.

Ending food scarcity

Ogbole say they are on a campaign to end seasonal food scarcity in Nigeria.

"Because we are the ones controlling everything that the plant requires, we are not depending on seasons. So it's no longer seasonal farming. It is just farming anytime of the year, meaning you can plant anytime of the year, we can harvest anytime of the year."

But setting up the aeroponic farm was not easy. It required financing of more than $180,000, Ogbole said. And, some people in Abeokuta were very much against this non-traditional method of farming.

"We were called wizards, demons, that we are doing something unnatural."

He added that it took a lot of effort to change people's minds about aeroponics.

Farming difficulties

In Nigeria, about 30 million hectares of farmland is being used, instead of the 78.5 million hectares required for food security.

In the north, communal conflict, militancy and desertification are the top reasons the farmland is being lost. And only 49 percent of the land is fertile, a situation that worries traditional farmers like Abubakar Ibrahim.

"I don't have any other place that I'll go to farm apart from here," he said. "And here, already the land has become weak."

No land needed

Aeroponics, however, does not require traditional farm work or much land. Nutrients for the plants are controlled by a recycling system, greatly increasing productivity.

Philip Ojo is director general of Nigeria's National Agricultural Seeds Council. He says the government welcomes new farming methods.

Ojo noted that with aeroponics, farmers can quickly increase planting materials, especially when using the method on root vegetables such as cassava and yam. So, his group strongly supports the technology.

The agricultural industry represents about 40 percent of Nigeria's economy. The government wants to greatly expand this percentage.

For now, most farmers lack the technical knowledge to increase productivity. They also need access to high-quality seeds to guarantee better harvests.

Technologically skilled farmers like Samson Ogbole are offering a new way forward.
