Editor's note

Locavorism is becoming big business as more Americans across the country embrace local foods. Farmers markets have exploded, local food sales are soaring, and even schools are sourcing more of their cafeteria fare from farms rather than national suppliers. At the heart of this trend are the “locavores,” a type of foodie who defies stereotypes. University of Oregon marketing professors Joshua T. Beck and Brandon Reich studied the ways and rituals of the urban locavore. Here’s what they learned.

Donors like Craig Newmark, the founder of Craigslist, make headlines with their big gifts aimed at shoring up news outlets and journalism schools. But the breadth and depth of philanthropic support for nonprofit media is a much bigger story, explains Charles Lewis, a pioneer of nonprofit media who is now an American University professor.

One of the lesser-noticed elements of the new federal indictments announced yesterday against 12 Russian government agents included allegations that some of them hacked into state and county government election records in at least three states. As the midterm congressional elections approach, along with countless other state and local races, we’ve collected perspectives from various authors for The Conversation about what could help prevent future spying and meddling in U.S. election systems.
