Deadline: 31st July 2021 | Age 18+ | In the Call for Code Global Challenge, you can join the fight against climate change by building and deploying open source solutions in the cloud. By participating, you’ll build critical skills for yourself and your teams and deploy solutions to help communities across the globe.

Built on open source principles, the Call for Code Global Challenge asks developers and problem solvers to form teams and develop solutions that address specific problems in unique, clearly demonstrable ways. The most successful solutions are those scoped to have the greatest community impact with the smallest technological footprint. Last year’s winner Agrolly is a perfect example, with its mobile application to help small farmers better understand what to plant, based on weather patterns and crop characteristics.

Three global focus areas:
– Clean water and sanitation
– Zero hunger
– Responsible consumption and green production


  1. Submissions must use one or more IBM Cloud services or IBM Systems. Use of sponsor or affiliate APIs and open source libraries is also encouraged.
  2. Teams of up to five (5) participants, each at least 18 years old, are allowed.
  3. A participant may not be part of multiple teams.
  4. Teams competing for the University Challenge must ensure that all team members are enrolled in an accredited institution of higher education.
  5. All team members must have accepted the 2021 Participation Agreement at the time they submit their solution to be eligible.(You accept the Participation Agreement when you register for the Global Challenge.)
  6. Applications must be new and built for the 2021 competition, but they may use code that was open sourced and publicly available to all other participants as of March 22, 2021.
  7. Winning teams will be subject to a code review after submissions close.
