In among the many problems caused by the decision not to fly in the ash-cloud, spare a thought for several very poor African countries who earn important foreign exchange by selling fresh fruit, vegetables and flowers to European markets and depend on air cargo to do so.
This evening here in Addis Ababa I bumped into the owner of one of the big flower-exporting businesses. He was looking pensive. Unseasonal rain had damaged part of his crop, and now he is unable to get his roses into European markets. A whole container had had to be destroyed because there was nowhere for them to go. On the back of an envelope, he calculated that the blockage of rose exports is costing Ethiopia about €200k a day. This may not sound very much but it is a big chunk of the export earnings of a poor nation.
