Volcanic ash from Eyjafjallajokull largely prevented air travel around Europe for a few days in mid-April.
Lots of people were stuck abroad, some still are.
Lots of perishable produce which would have been airfreighted was stuck in the country of origin and in some cases wasted.
=1. Diverting perishable produce, new jobsEdit
Reports of the situation in Kenya, where exporting horticultural produce is a major avenue for getting international money. [blog post based on report from Guardian.]
More coverage from BBC, video from a rose factory, where non-exportable flowers are being turned into compost.
Apparently the horticulture industry needs a lot of reorganizing anyway - I hear there is striking drop in water levels in Lake Naivasha as the horticulture industry is taking out much more than nature is feeding in (personal report from a friend/eyewitness). So this is a good challenge for water security folks as well!
=2. Networking stranded travellersEdit
Facebook group: When Volcanoes Erupt: Facebook Group: Guide for stranded travelers
For Rides: Roadsharing
Loding and Rides: Get Me Home
Another web page for the stranded: Volcano Help
Another facebook page for Europeans stranded: Gathering Under the Ash Cloud
Twitter hashtags: #ashtag, #getmehome, #putmeup, #volcano
Crisis Mappers (Not specific to volcano problems but much useful information): Crisis Mappers
Advice from British Foreigh Office: 'Help for British Nationals stranded abroad'.
A creative challenge if you are stranded: "This is an open call to designers, writers, photographers, illustrators, art directors and anyone else who is stranded by the ash cloud, and would like something to do." Andrew Losowsky is proposing to make a magazine and wants contributors, editors, anything - the only criterion is you have to be unintentionally stranded somewhere!
Could people with useful skills be matched up with opportunities to volunteer? For example teachers and doctors? We could start collecting resources networking stranded travellers.
