Summary: | One of the challenges of disaster science is finding connections between different areas of knowledge –interdisciplinary approach– and to be transdisciplinary, i.e., engaging non-scientists in the formulation and development of research, in the co-production of knowledge. Developing people-centered warning systems is a scientific challenge and one of the recommendations of the United Nations in the Sendai Framework for Disaster Risk Reduction 2015-2030. This article aims to discuss theoretical and interdisciplinary methodologies to support the development of community-based early warning systems to cope with disaster risks. Using bibliographic review and field research with qualitative methods in Nova Friburgo, Rio de Janeiro, Brazil, the article shares preliminary findings of a workshop on CBEWS. There are important shortcomings regarding the concept of CBEWS, the subsystems involved and how to find ways for implementation.
