This document discusses the history and evolution of participation in disaster management and post-disaster reconstruction from the 1970s to present. It begins with an overview of the history of participation and its role in post-disaster reconstruction. It then examines different eras of participation, from the participatory approaches of the 1970s, strategic planning and public-private partnerships of the 1980s, new communication forms of the 1990s, and the integration of communicative strategies in modern case studies. New technologies like GIS, global risk modeling, and disaster photography ontologies are explored as ways to enhance participation.
