FYI came across this going on in the UK:
"We volunteer at radical UK growing projects. Are you interested in
land rights, food sovereignty, low-impact living, permaculture, seed
saving or organic, urban or community growing? If you answered ‘yes’
to any of those, join us at the cutting edge of sustainability in the
UK."

And extremely exciting, a proposed nuclear site has been occupied and
is being turned into a farm, as part of Reclaim the Fields:
"We are determined to create alternatives to capitalism through
cooperative, collective, autonomous, real needs oriented small scale
production and initiatives, putting theory into practice and linking
local practical action with global political struggles."
