Community Theatre tracked the memory landscapes of local residents affected by tidal flooding, through continuous engagements with them, to explore the region’s historical, cultural, and social landscapes. This journey down memory lane furnished comprehensive data on people’s lives — including their local history, myths, songs, and rituals — and environmental issues. Training in theatre production enabled the local residents to script the drama themselves, and to enact it. This recasting and reinventing of the Community Theatre helped in evolving a theatre language of the marginal and the vulnerable, besides stamping their voice and agency in climate change interventions through the medium of community theatre.
