The Buckminster Fuller Challenge (BFC) announced six finalists for the tenth anniversary of its annual international program. The challenge's call-for-proposals was released back in January, welcoming submissions from all fields, and seeking projects with "visionary, comprehensive, anticipatory, ecologically responsible, feasible, verifiable, and replicable" strategies to help overcome humanity's most critical problems. Winning proposals demonstrate "more than a stand-alone idea or innovation," noted the same brief. "[The BFC] looks for visionary, whole-systems solutions that demonstrate both a clear grasp of the 'big picture' and a focus on a well-defined need of critical importance." This year's program received 460 submissions from 102 countries.

According to the institute, the Fuller Challenge Review Committee is in the process of evaluating the six proposals to select a winner, who will receive $100,000. In addition to the grand prize, the finalists, semifinalists, and select entrants will benefit from the institute's Catalyst Program—which according to the BFC, provides additional resources and opportunities including "additional funding, pro-bono legal services, fast-tracked access to accelerator programs, mentorship opportunities, and international press coverage." The winner will formally be announced this October and the competition's anniversary celebration will be held Nov. 10-11 at A/D/O in Brooklyn, N.Y., which will be open to the public.

Last year's winner was the Rainforest Solutions Project, headed by Tides Canada Initiative—a nonprofit focusing on social and environmental issues—in collaboration with environmental advocacy organizations Greenpeace, Sierra Club BC, and Stand.

Below are this year's six finalists:
