Tamir Nir, a second-year rabbinical student at HUC-JIR/Jerusalem, recently introduced compost to the Jerusalem campus. Nir is involved in sustainability and ecological issues in Jerusalem in general and in particular with the community that he founded in Beit Hakerem. The community, "Achva Ba'kerem," is a chavurah of Beit Hakerem residents committed to improving the quality of life for families living in urban settings. They have created a community garden for growing vegetables and greens of all sorts. In addition, they have ongoing Torah study, cultural events, and social action projects. Nir is emerging as a leader in the Independent Communities and Chavurot Movement in Israel. Next week, the Minister of the Environment in the Israeli Government will be visiting their community garden as a model for community building and ecology.
