Leonardo E. Figueroa Helland (PhD) is an Associate Professor of Environmental Policy and Sustainability Management at The New School. He leads the Indigeneity, Decolonization and Just Sustainabilities section of the Tishman Environment and Design Center. He is a mixed-blood scholar (Indigenous Mesoamerican and Euro-America) whose work underlines how Indigenous resurgence, decolonization and the revitalization of biocultural diversity, alongside social, environmental and climate justice movements, are vital to overcome planetary crises. Building and extending beyond his doctoral work on Indigenous Philosophy and World Politics, his latest writings appear in the Journal of World Systems Research, the journal Perspectives on Global Development and Technology, the volume on Social Movements and World-System Transformation, and the volumes on Anarchist Political Ecology and on Contesting Extinctions: Decolonial and Regenerative Futures. He is currently working on a manuscript titled Indigenous Resurgence beyond “Anthropocene” Collapse: From Planetary Crises to Decolonization.
