Who gains from the boom in African fresh vegetable exports?

Fresh vegetables exports from Africa to the European Union have increased rapidly in the past decade. In the UK, what was once a small- scale trade in Asian vegetables such as chillies or okra sold to wholesale markets, is now high volume and dominated by the biggest supermarkets. Their requirements have transformed horticultural export trade in Africa. Production, processing and logistics are far more sophisticated. Skills and employment in Africa have improved but trade barriers have increased. What does this mean for small growers and exporters? How will they benefit from this fast-growing trade?
