Hazon has a wonderful program for creating Jewish CSAs [farm share programs] including help with finding a farmer and other logistics. The Hazon program incorporates a significant amount of Jewish learning and programs for the entire family. This program, Tuv Ha’aretz (meaning both "good of the land" and "good for the land"), is now accepting applications for the 2010 season. Details can be found here.
Many synagogues and JCCs around the country are running these programs, but none yet in the Boston area. In some communities multiple synagogues are working together (some across denominational boundaries) to host a CSA.
Please consider this for your community. Pass it along to your JCC director, your Rabbi or other leader.
