Short summary: Understanding the relevance of population dynamics on sustainability is fundamental because human activities are, by now, undoubtedly responsible for anthropogenic climate change. The already visible impact of climate change, meanwhile, can influence demographic behaviour and population dynamics. This session explores the reciprocal relationship between climate change, population dynamics and sustainability by presenting novel empirical findings based on various untapped data sources. The first and second papers focus on the impact of climate change on demographic outcomes, that is fertility and mortality. Based on harmonisation of Demographic and Health Surveys for >60 low- and middle-income countries, the first paper investigates whether and to what extent exposure to extreme climate events affect monthly and quarterly fertility rates measured at a refined spatial scale. Considering exposure to both climatic events and air pollution, the second paper explores to what extent these environmental hazards interact and increase mortality risks of children age under five in India. The third paper considers the outcome related to well-being. Using Twitter data, this paper investigates how experiencing extreme climate events influence underlying positive or negative sentiments with a focus on demographic heterogeneity. Social media data allow real-time measurement of climate-related sentiments which are not possible in a survey setting. All three studies will contribute new insights into the fields of population influence on sustainability and climate impact on population dynamics.
