Many of the Earth Stewards are graduates from the UNESCO-IGCP/Earth Project, Young Ambassadors Programme.

During 2022 the Earth Stewards are helping the team at IUGS showcase the Earth Sciences. We especially wish to share knowledge with the IUGS community and the public, about how we can solve some of the biggest environmental challenges faced by the world today. We value our Earth Stewards independent views on topics covered and are keen to learn more from these dynamic and passionate Earth Stewards over the coming months.
