Mary Seton Corboy looks like an intellectual and a farmer collided, wearing soiled covered clothing, thick-rimmed glasses, and blessed with the gift of a permanent tan. She keeps her agenda and checks her email with a Blackberry, hands out business cards, and makes sure the farm is up to date with social media tools such as Facebook and Twitter. The 51 year-old is charming with a twist of ironic wit and unsuspected strength for a petite, soft-spoken woman. She is a revolutionary, community activist, and an inventor. Mary Seton Corboy is an urban farmer.

Greensgrow Philadelphia Project, a nonprofit organization that promotes social entrepreneurship through the reuse of land once deemed useless, has appointed the following members to its board:

Justin DiBerardinis is legislative director for City Councilwoman Maria Quiñones Sánchez.

Just three miles north of downtown Philadelphia, tucked within a sea of tightly packed row houses, lies Greensgrow Farm. Much is crammed into this one-acre setting. And although there is a full-service garden center, it's the many other things going on there that have made the farm the nationally recognized leader in urban sustainable farming.

The words "urban" and "farming" typically are not used in conjunction with one another, but in one Philadelphia neighborhood, the two have been fused to create an agricultural oasis that provides much more to the local community than its produce and plants.

From 10 a.m. to 3 p.m. on Saturday, Oct. 3, Greensgrow Farm, 2501 E. Cumberland St. in Kensington, will branch out into the community with a Fall Festival, which will introduce visitors to the unique mission of the city farm and provide an outlet for residents to socialize.
