Tom Colicchio is one of the slated speakers for this year’s South by Southwest Eco Conference.

South by Southwest Eco, the little sister conference to the big SXSW festivals in March, is coming up in October, and last week, ‘Top Chef’ host and food activist Tom Colicchio was added to the list of speakers.

SXSW Eco always has a number of agriculture and food policy panels, but it has lacked the big name food celebrities that usually come to the March conference.

This fall, Colicchio, whose role as a food advocate has grown as his own celebrity has, will join Raj Patel, Robert F. Kennedy Jr., Bill Nye and Civil Eats’ Naomi Starkman for the conference at the Austin Convention Center October. 10-12.
