(19:30 - 21:30 Hs Brasilia)
Keynote: "Sustainability, Land Use & Policy Impact"
This keynote explores the urgent challenges shaping climate-change research today and reflects on the speaker's path from nonprofit work to a career in academic research.
Joyce Brandão, Socio-Environmental Research & Practitioner
Joyce Brandão is a Brazilian socio-environmental researcher and practitioner with over 15 years of experience in sustainable agriculture, forest conservation, and rural development. She is currently a PhD candidate in Geography at the University of Cambridge, studying how political shifts shape the effectiveness and equity of forest-focused supply chain policies (FSPs) in Brazil’s soy and cattle sectors.
Joyce's career spans leadership roles at Solidaridad Brasil, WWF-Brasil, and Fundação Getúlio Vargas, where she managed programs to combat deforestation and promote low-carbon agriculture in the Amazon and Cerrado.
Joyce’s work bridges science and policy, advancing equitable solutions for forest conservation and livelihoods. She is a co-author of multiple international publications on agro-commodity governance and sustainability transitions across tropical landscapes.
Professional Development Panel

Task Force "Climate Change" Panel
Meet the Bridges '25 Scholars, their research and their missions.
Panel Moderator
DS Bridges '25 Scholar
Leticia Ferreira de Sousa, PhD
Leticia explores how microbial co-inoculation can protect soybeans from drought and other abiotic stresses. Her research aims to sustain crop performance under changing climate conditions—supporting farmers, supply chains, and food security.
DS Bridges '25 Scholar
Izaias investigates how extreme rainfall patterns are shifting and what that means for urban drainage in Brazil’s Northeast. By integrating data analysis with practical infrastructure considerations, his work helps cities anticipate risk and plan for resilient water systems.
