Planetary Health Alliance (PHA) and Terran Collective Partner to Create Online Platform Hylo to Advance Planetary Health

January 26, 2021

We live in a world of networks, constellations, communities, and ecosystems. An interconnected and imperiled society that — perhaps now more than ever — requires trustworthy and effective online tools to harness collective values, sensemaking, and action from the local to global scale.

The Planetary Health Alliance (PHA) and Terran Collective are thrilled to announce their purpose-driven partnership to further the development of Hylo: a digital social coordination platform to amplify cooperation among people regenerating communities and the planet. The PHA has used Hylo to organize “who’s doing what where” in the global planetary health community since 2017, and in April 2021, Hylo will be re-launched with features especially designed to improve the connectivity and impact of diverse networks such as the Planetary Health Alliance.

Free to use and accessible by both web and mobile platforms, Hylo users can easily find other changemakers according to geography, skills, and interests; share announcements, discussions, requests, and offers; and start projects and groups to take action for their cause or goals. The PHA expects Hylo to revolutionize the way its members build genuine relationships; brainstorm and problem solve; exchange ideas, stories, resources, and lessons learned; and take concerted action toward a healthier and more equitable future for all.

Based at the Harvard T.H. Chan School of Public Health, the Planetary Health Alliance is a consortium of over 230 organizations and thousands of individuals from around the world committed to understanding and addressing global environmental change and its health impacts. Members of the Alliance envision a world where all people thrive by protecting and regenerating Earth’s natural systems for generations to come, and work towards a mission of promoting, mobilizing, and leading an inclusive, transdisciplinary field of planetary health and its diverse science, stories, solutions, and communities to achieve the Great Transition — in short, a comprehensive shift in how human beings interact with each other and with Nature.

Terran Collective is a California-based non-profit that builds systems and tools for a regenerative future. When Hylo was open sourced in 2020, Terran began stewarding the platform as part of their mission to create technology to foster trust and collaboration. They work with values-aligned partners such as PHA to build and shape Hylo to meet the specific needs of organizations that convene large networks of humans working toward a common goal.

We are honored to be partners in this work together and see this people-driven technology as a vital component of the regenerative movement. We invite you to consider how Hylo can better support and empower your organization, community, or individual goals, and to join the PHA and Terran Collective on Hylo after the 2021 relaunch! Hylo currently hosts 2500+ active users and over 50 active communities.

Hylo will be relaunched in time for Planetary Health Week: April 25–30th, 2021, which will build upon the momentum of Earth Week and feature the 4th Planetary Health Annual Meeting. This free and virtual conference-festival will be co-hosted by the Planetary Health Alliance and University of São Paulo with the theme: Planetary Health for All: Bridging Communities to Achieve the Great Transition. Hylo is the perfect tool to bridge our diverse communities and spark sustainable collaboration in the transdisciplinary field of planetary health.

Those who wish to learn more about the collaborations between the PHA and Terran Collective can attend the Hylo Satellite Session at the 2021 Planetary Health Annual Meeting, subscribe to the PHA’s monthly newsletter and social media, and follow Hylo’s transparent product roadmap here. Additionally, eligible organizations (and soon individuals!) are encouraged to formally join the Alliance, and anyone can donate to the Hylo initiative to become a founding stakeholder and support ongoing efforts to build collaborative pathways towards planetary health.
