0

Call for Code founding partner IBM and its creator, David Clark Cause, have announced the winner of the fourth annual Call for Code Global Challenge, which invited innovators across the globe to combat climate change with open source-powered technology. The top prize this year went to Saaf Water, an accessible water quality sensor and analytics platform created, in particular, for people living in rural localities.

Saaf Water will receive $200,000 and support to incubate, test, and deploy their solution from the IBM Service Corps and expert partners in the Call for Code ecosystem. The India-based team will also receive assistance from The Linux Foundation to open source their application so developers around the world can improve, scale, and use the technology.

A panel of some of the most eminent leaders in sustainability, business and technology, including former President Bill Clinton, awarded Saaf Water the grand prize. Four runners-up were also recognized. Each finalist created a solution to problems addressing the climate change competition’s three sub-themes: clean water and sanitation; zero hunger; and responsible production and green consumption.
