Cassava becomes lucrative cash crop

2012-06-07 21:24

Johannesburg - The seeds of prosperity for some rural Africans may lie in a crop that has sustained them with calories for centuries but has generated virtually no wealth for their poor countries.

Cassava - with its starchy root used to make tapioca - thrives in Africa's tropical climates, through drought or deluge, but maize and other crops have had distinct advantages over the hardy tuber. Until now.

Cassava can remain in the soil for a couple of years but its main drawback has been that it has to be processed within 48 hours of harvesting or it spoils.

An unlisted Dutch-based company called DADTCO has developed a processing method for cassava and dispatches a mobile unit with the equipment to rural villages, so farmers don't have to harvest their crop until it arrives.

The implications could be revolutionary on a continent where much economic activity still centres on small-scale farming.

The potential has already been spotted by global brewer SABMiller which has started making beer from cassava in northern Mozambique.

"This creates we believe a fly-wheel for commercial cassava production in Mozambique," Mark Bowman, the brewer's managing director for Africa, told the Reuters Africa Investment Summit in April.

"In the short term 1 400 or 1 500 farmers benefit directly. We expect we can grow that up to 6 000 farmers as the product grows," he said.

DADTCO chief executive Peter Bolt told Reuters that similar projects are being rolled out in Zambia, Ghana and South Sudan with more to follow.

"Our target is to roll out in 26 or 27 sub-Saharan African countries in the next couple of years," he said in a telephone interview from his Netherlands base.

More than beer

And it's not only brewers that are focusing on cassava.

Unilever, the Anglo-Dutch consumer goods giant, is targeting the root to make sorbitol, a key ingredient in toothpaste and other products.

Unilever and some of its business partners are currently in talks about investing in a starch complex to process cassava into starch or sorbitol in Nigeria, which is the world's biggest producer of the root and a big market for Unilever's 3 billion euro a year Africa business.

"We are already in exploratory talks to source 100 000 tons of cassava per year for processing in Africa into sorbitol for use in our oral care products like toothpaste," said Frank Braeken, Unilever's executive vice president for Africa.

It remains to be seen how far the "cassava revolution" can go but it surely raises new hope on the economic and food security fronts for the world's poorest continent.

When it comes to pure sustenance and survival, cassava is hard to beat because of its durability, even if maize and other staples generally have higher starch contents.

According to the International Institute of Tropical Agriculture, 37% of Africa's dietary energy comes from cassava and per capita consumption on the continent is close to 80kgs per year.

But instead of being grown primarily for household consumption, expect more cassava to be stored in the ground for eventual sale.

Almost like money in the bank.

    How do you deal with its cyanide content? I always wondered about that.

      Haven't heard anything about the cyanide problems, but I do know its easy to grow, just break a branch off and plant it, you can eat the leaves as well as the roots, very little of the plant need go to waste. You can boil it and eat it, fry it, makes great chips eat it raw, and you can dry it and powder it, makes either a porridge or bread, crop yield is far higher than mealies or potatoes and isn't as harmful to the soil.

    Sounds good... I'd be keen to try some stuff...
