37% of the UK population (26M)
will be over 60 by 2050 — that’s
you lot!
only 13M will be children . . .
42. local food growing: growingbirmingham.org
why bother?
social & civic: conviviality . . . it’s fun . . . relatively easy . . . kids
love it . . . makes the city look great . . . it’s social glue
meeting obesity & other health issues: ‘magic’ happens when
communities have food growing in their midst . . .
a good day’s work: labour intensive . . . and
horticulture is an inherently optimistic activity,
often highly sociable . . . a lifetime’s activity
where expertise is gifted from one to another
& there are career opportunities at all levels
decarbonisation: city communities using their waste to fuel their
energy . . . & (maybe) growing biomass on contaminated land

very, very very
fresh fruit & veg
tastes absolutely fantastic!

BIRMINGHAM SUSTAINABILITY FORUM: feeding the city
eating as “social glue”
protein shortages
being smarter about using food:
buying less, eating less, wasting less
Will the lights go out? & Birmingham is where diet & health for individuals . . .
distributed energy systems:
potential to supply 10-50% of the
[happy] children eat [well]
the health of the whole
£2.6bn we use now
population . . . and
regeneration or game-changer?
its impact on social & civic

infrastructure
➡ waste-energy nexus?
➡ exportable social and engineering urban agriculture
technologies? urban horticulture . . .

This is land farmed by my in-laws, Mick and Pat - and this image is what their highly fertile, intensely farmed land looks like. They grow wheat, sugar beet, rape seed and spuds, sometime onions, daffodils\n\nWhat if . . . their crops fail? What’s the impact on us?\n\nWhat if . . . they decided to eat locally produced food?\n\nNote: In Grandad’s time, farmers there weren’t wealthy, quite a lot was subsistence farming, plus produce to placess like Leicester and Peterborough. \n\nThe War changed things, including lots of land girls drafted into the area to do the labour.\n\nIt was labour-intensive until combine harvesters. Around 1980, I saw a potato harvester for the first time, doing the rounds of the local farms. One man, a great big machine and large fields of spuds from ground to branded bag in a few hours.\n
