Do you have an innovative idea that could change the way the world feeds itself? Food + City, formerly the Food Lab at the University of Texas, wants to know about it. The nonprofit is again offering a challenge prize to entrepreneurs, startup groups and students, asking them to uncover lasting ways that we can improve the logistics of feeding cities around the world.

This is the second year for the competition, which in February awarded $30,000 to five startups from Austin, Atlanta and San Francisco.

If your idea for a business, product or process is the best of the bunch, you could win big — Food + City sponsors are increasing cash awards to $50,000 this time. The submission process starts Sept. 1, and the deadline for turning in your project is Oct. 15. To submit a proposal, visit
