In pictures: Growing khat

The Kenyan farmers who grow the mild stimulant khat, which is banned in some countries, have had a tough year.

Exports dropped by 40% when its consumption was banned in Somalia, their main market, by Islamists during their six-month rule of the south and centre of that country.

But after Somalia's transitional government, backed by Ethiopian soldiers, defeated the Islamists, daily khat flights from Kenya to Somalia have resumed.
