Why is it essential for science to collaborate with Indigenous People and traditional communities? In this video, experts from CIFOR-ICRAF Brazil, Henrique Marques, explore the importance of involving those who have lived on and cared for these lands for generations. Working alongside these communities not only enriches the research process but also brings context-specific insights crucial to addressing today’s environmental challenges in places like the Amazon and Cerrado. Through “research in development,” we co-create sustainable solutions, engage in citizen science, and foster meaningful exchanges across global and local knowledge systems to support the sustainable development goals.
