I joined the Oxford Real Farming Conference online this year, and despite a slightly shambolic experience due to technical issues (the streaming went down, YouTube was there as a backup option but lots of people were in the chat asking where to go), there were some useful sessions.
A playlist of all of the recorded sessions is here. Two highlights for me:
Findings from a citizen engagement project by the Food, Farming and Countryside Commission talking with people around the UK about what they really wanted from food, with a great follow-up panel discussion.
An illuminating talk from Mandy Barber of Incredible Vegetables on the range and diversity of perennial veg. I want to start growing a bunch of this stuff.
