Climate Change Documentary Film Analysis: Before the Flood

Abstract

This paper analyzes Before the Flood (2016) in relation to climate change, population health, and health equity. The documentary film analysis focuses on two interconnected climate-related issues: extreme rainfall and food insecurity in South Asia, and sea-level rise and displacement in Kiribati. Using climate justice, environmental justice, planetary health, and United Nations Sustainable Development Goal frameworks, the paper argues that climate change is not only an environmental crisis but also a public health issue shaped by structural inequities. Drawing on peer-reviewed literature, the analysis demonstrates how climate-driven disruptions threaten agricultural livelihoods in India and Bangladesh, contribute to food insecurity and mental health stress, and pose existential risks to Pacific Island nations through freshwater insecurity, displacement, and cultural loss. The paper concludes with three evidence-informed, equity-centred recommendations: integrated early warning systems combined with climate-smart agriculture and weather-indexed crop insurance for South Asian farming communities; a dignity-centred planned relocation framework for Pacific Island nations; and mangrove ecosystem restoration as a cross-cutting, nature-based solution. Overall, the findings underscore that effective climate action must address ecological, social, and structural determinants of health together, and that health equity cannot be achieved without confronting the systemic inequities that leave vulnerable populations least able to adapt to a changing climate.
