Cameroon police and customs officials say they blocked scores of trucks that attempted to smuggle cash crops in the past two weeks from northern towns and villages into Nigeria.
Police say they seized wheat, corn, rice, cocoa, and cotton since launching a temporary ban on all crop exports to Nigeria on June 13.
Cameroon’s ministry of trade says the ban was needed as it loses $165 million each year from the smuggling of cash crops to its northern neighbor - 60% of the total trade.
The government ordered hundreds of police to the border and to track down at least 12 trucks that fled from authorities.
Cameroon’s farmers say the ban will be hard to enforce along the porous, 2,000-kilometer-long border.
Baba Ahmadou is the spokesperson of the Association of Cereal Farmers on Cameroon's northern border with Nigeria.
Speaking by phone from the border town of Mara, he says many farmers are not able to store their crops for selling in Cameroon.
Ahmadou says Cameroon does not have enough facilities to protect cocoa, wheat, corn, rice and sorghum from moisture, dust, and [insect] swarms that invade and destroy crops after harvest. He says farmers prefer selling their produce to a ready Nigerian market because rice, corn, and raw cotton processing equipment is scare, old, and there are regular power cuts.
Ahmadou says selling to Nigerian merchants is also more profitable, and he cites the example that farmers can get about 20% more for a 50-kilogram bag of unprocessed rice.
Cameroon’s government complains it pays subsidies to farmers to sell their cash crops locally and at agreed prices.
The ban was announced by Cameroon’s trade minister Luc Magloire Mbarga Atangana.
He says they are aware of the challenges for the government and the farmers.
"One of the challenges, of course, is the inadequacies of post-harvest processing and storage facilities," he said. "The government has developed some programs to process 40 percent of our total production, and now with the prohibition of child labor and with the prohibition of deforestation, those people who are destroying forests to create new plantations will not have access to the international market."
Cameroon's Ministry of Agriculture says illegal cocoa exports to Nigeria spiked after anglophone separatists in 2017 launched a rebellion against Yaoundé.
The rebels are seeking to create a breakaway state from Cameroon’s French-speaking majority.
Shivron Arrey, a cocoa exporter in Kumba, an English-speaking Southwestern town, says the rebels stop them from selling the cash crops to French-speaking towns.
"With the separatists’ crisis, enterprises no longer come to buy cocoa," she said. "Fighters destroy vehicles belonging to companies that attempt to buy. Cocoa farmers were abandoned to themselves. The easiest market they could count on was across the border in Nigeria."
Cameroon authorities say the military is protecting farmers from rebels so the domestic trade can resume.
But farmers say smuggling to Nigeria will continue as long as their options are facing separatist violence and lower prices at home or risking illegal exports across the porous border.
