Nigeria's recent six-month ban on raw shea nut exports, intended to boost local processing and increase profits for women, has instead backfired. The policy has caused a collapse in shea nut prices and significantly reduced the income of women who depend on the industry.

• Before the ban, women like Hajaratu Isah earned up to 5,000 naira ($3.30; £2.45) daily; now, their income has dropped to less than half.
• The ban, imposed in late August, aimed to increase Nigeria's share of the $6.5 billion (£5 billion) global shea industry, despite Nigeria being the world's biggest producer, accounting for nearly 40% of the world's shea crop.
• The lack of sufficient local processing capacity, with a new factory like Salid Agriculture Nigeria Limited's plant having an annual capacity of 30,000 tonnes, means many traders are left with unsellable stock.
