My half acre suburban food forest produces a lot of surplus that I would love to trade, but I haven't been able to figure out a way to do trades that doesn't suck up tons of my time (of which I do not have a surplus ) Perhaps something like this could work?
I think there are many ways for a farm to pay it forward, and that if they are not, then they are just not being creative enough.
I know in my own sickness (cancer), and lack of money, Katie and I still manage to do our Rock the Flock event. When asked by the newspaper why we put on a benefit concert for drug addiction recovery, Katie said it best, "we do not have much, but we have room."
And we do. We literally have room, and have a nice vista so that it is scenic.
Not all farms have that, but that is what we have, and what we use to give back to the community. And in our own time of need, the community has stepped in to help.
It would be impossible to list all the ways a farm could give back to the community, but a few might be, sponsoring a child to go to horse camp, or maybe it is giving food to the local food pantry, or maybe it is just giving 10% of the farms profits to charity...it can be much more, or much less than that. But every farm can give back to the community they are in, if they are creative enough in figuring out how.
Just put the cards in their christmas stocking and PRESTO! They get it now! It's like you're the harry potter of permaculture. richsoil.com/cards
