HARVARD SQUARE- Patrons of the burgeoning worm poop market were able to stock up on supplies at the first annual Urban-Ag Fair in Harvard Square on Sunday afternoon. The fair came of a collaboration between the Harvard Square Business Association, growers, producers and residents who support local, sustainable agriculture.

Winthrop Street was closed to traffic to accommodate tables and tents laden with everything from local cheeseburgers to WormJava, a cocktail of worm poop concentrate that purportedly enhances soil and encourages plant growth. Numerous local organizations were out in force with flyers, giveaways, and free locally grown string beans in an effort to broadcast their support for urban-agriculture and all things “green.”

The Winthrop Street location was chosen as an homage to the areas first market, held in the same spot starting in 1630.

Representatives from nearly all the organizations present expressed a lot of excitement about the event and its specific focus on local food and urban agriculture. Lise Holdorf from Citysprouts, which provides after-school programs about gardening to all K-8 school in Cambridge, voiced the popular sentiment regarding the novelty of the fair.

“Urban-ag is what we’re all about. We want to share it with the community… the fair definitely focuses on people interested in [that],” she said.

That was the general consensus amongst myriad organizations from the Harvest Co-Op- a member owned full service supermarket- to Season to Taste Catering- which serves up “all farm fresh, local, seasonal food” for a 25+ head count. Small business owners reveled in the specialized attention lavished on them by progressive-looking, possibly vegetarian fairgoers who shared a vision of a simpler, greener lifestyle.

Season to Taste attracted the largest crowds with live demonstrations and free samples of some simple, locally grown appetizers. Like a “Top Chef” in an elimination challenge, chef Robert Harris served up a refreshing watermelon and feta cheese salad in a cucumber “shot glass.” All ingredients were seasonal, and locally produced, as per the company’s mission statement. The food was gone almost as quickly as it was made, and reactions were exuberant.

“I was going to have Redbones cater my graduation party, but now I’m thinking I have to have this,” said Brendan Johannsen, 21, a Tufts senior enamored of the hors d’ouevres.

“Sometimes people think that eating locally means making sacrifices, and you can see here that’s not true.,” said Lauren Andler, a representative of the catering company. She stressed the company’s focus on agriculture and a local growing community as well as the importance of getting customers to “really think about eating responsibly.”

Also represented were organizations that targeted not only eco-conscious consumers, but also businesspeople. The Sustainable Business Network (SBN) offered their card to those who might be interested in their Sustainable Business Leadership Program. The network offered six- and nine-month program options to help coach businesses on enacting locally- and environmentally-conscious practices.

SBN was also advertising their monthly “ALLocal Dinner,” which is to be held at Upstairs on the Square in Harvard on Monday October 19.

“It’s a great challenge for the chef, and it really raises awareness that local food can be luscious, available, and delicious using only local and seasonal ingredients… everything right down to the salt,” explained volunteer Natalie Syrion. The dinner will feature a five course meal sourced and processed in New England and as close to Cambridge as possible.

“It’s really about bringing community back to community,” Syrion said.

Other community organizations present included the Somerville Garden Club- advertising for their next monthly meeting to be held on October 14- and Gardens for Good- which held a paneled taste test for “the tastiest, the biggest, the most interesting — and in some cases, the ugliest — fruits, veggies, baked goods, honey, flowers, preserves, pickles and eggs.”

Fairgoers could also stock up on supplies for a hearty urban garden. Aside from the WormJava, which was sold in brewable teabags and bottled concentrates, visitors could purchase home compost bins, aerated dirt, seed packets, and plants.

The wide array of organizations present was an indication of the growing popularity and interest in the “urban-ag” and local food scene. Fair participants and attendants all expressed enthusiasm and optimism regarding the future of local food and the people who grow, harvest and sell it.
