From Kickstarter.com:

The Urban Farm Collective began in 2009, educating, growing and sharing food in inner NE Portland, Oregon and exchanging produce exclusively via a barter system. The first year we grew on just one lot; by the next year we’d grown to four sites.

This year, we have been accepted as a project of Oregon Sustainable Agriculture Land Trust and have the opportunity to take on five new plots, bringing our total garden space up to more than 1/2 acre.

If we are able to transform these new lots into gardens, this would create something that as far as we know exists nowhere else in the country: a non-profit urban farm, exchanging produce to participants via barter and donating significant amounts of fresh, local produce to the community at large.

Volunteer gardeners and land owners are already on board; all we need is the money to transform the lots. The money will go toward purchasing irrigation systems, tools, greenhouse supplies, path and fence building materials, water catchment systems and harvesting supplies.
