Juneteenth, celebrated on June 19th, marks a pivotal moment in American history when the last enslaved African Americans were emancipated in 1865. As we honor this day of freedom and reflection, we reflect on the contributions of Black leaders who have shaped and continue to shape the environmental movement. From pioneering conservationists who have dedicated their lives to protecting natural landscapes to tireless advocates for environmental justice who strive to ensure equitable access to clean air, water, and land, these influential figures remind us that the fight for justice extends beyond social and economic realms into the very fabric of our environment. Join us as we celebrate the achievements and legacies of just a few remarkable individuals who have driven change for a more sustainable future for us all.

Vanessa Nakate
Climate justice activist and Founder of Rise Up Climate Movement
Vanessa Nakate’s conservation leadership began with a small protest on the streets of Kampala to draw attention to the climate emergency and destruction of the Congo Rainforest. As her message spread across Uganda and beyond, she founded the Rise Up Movement, to amplify the voices of activists from across Africa. In 2022, she was appointed UNICEF Goodwill Ambassador and has addressed world leaders at multiple climate summits. At the 2023 UN Climate Change Conference, she urged delegates to put people first instead of profits, to make polluters pay, to cancel debt and direct climate finance toward the most vulnerable countries that did not create the climate crisis, while making sure fossil fuels are not part of their development. Her activism has brought attention to the voices of young activists from the Global South and the need for urgent action on climate change.

Throughout the dialogue, speakers highlighted the importance of recognizing the expertise and human capital that already exist within frontline communities. Frontline communities know what they need and have ideas for solutions to meet their communities’ challenges, but these communities often lack investment. One barrier to investment is the spatial mismatch between community-led projects and environmental markets. Investors typically require larger spatial scales for investment, while most community-led projects operate at much smaller scales. For example, the Blue Carbon projects highlighted at the Symposium struggle to access carbon markets because they are small and not aggregated.
Regenerating healthy biodiversity and building climate resilience is hard. Many of us put enormous amounts of energy, time, and money into creating positive change while experiencing tremendous uncertainty around our impact. We must pause and ask ourselves, ‘
The value of rooting our climate and biodiversity work in relationship-building reverberated powerfully throughout the Symposium. Despite the urgency of the climate and biodiversity crises, speakers encouraged the conservation community to slow down and intentionally build meaningful relationships with partners and leaders from across sectors and organizations, and particularly with the frontline and Indigenous communities who are central to this work. Creating an effective and truly inclusive NBS community necessitates a deeper understanding of and ability to communicate with all those touched by the biodiversity and climate crises to develop shared values and a common language. For North America to reach a nature-positive future, we must lead with community and create solutions built on a foundation of trust.
